Basho and Cisco have integrated Riak and Mesos

Cisco and Basho have successfully demoed the Riak key value store running on Apache Mesos, an open source technology that makes running diverse, complex distributed applications and workloads easier.

Basho helped create and commercialise the Riak NoSQL database and worked with Cisco to pair Mesos with Riak’s own automation and orchestration technology, which the companies said would help support next gen big data and internet of things (IoT) workloads.

“Enabling Riak KV with Mesos on Intercloud, we can seamlessly and efficiently manage the cloud resources required by a globally scalable NoSQL database, allowing us to provide the back-end for large-scale data processing, web, mobile and Internet-of-Things applications,” said Ken Owens, chief technology officer for Cisco Intercloud Services.

“We’re making it easier for customers to develop and deploy highly complex, distributed applications for big data and IoT. This integration will accelerate developers’ ability to create innovative new cloud services for the Intercloud.”

Apache Mesos provides resource scheduling for workloads spread across distributed – and critically, heterogeneous – environments, which is why it’s emerging as a fairly important tool for IoT developers.

So far Cisco and Basho have only integrated Basho’s commercial Riak offering, Riak KV, with Mesos, but Basho is developing an open source integration with Mesos that will also be commercialized around a supported enterprise offering.

“By adding the distributed scheduler from Mesos, we’re effectively taking the infrastructure component away from the equation,” Adam Wray, Basho’s chief executive officer told BCN. “Now you don’t have to worry about the availability of servers – you literally have an on-demand model with Mesos, so people can scale up and down based on the workloads for any number of datacentres.”

“This is what true integration of a distributed data tier with a distributed infrastructure tier looks like, being applied at an enterprise scale.”

Wray added that while the current deal with Cisco isn’t a reselling agree we can expect Basho to be talking about large OEM deals in the future, especially as IoT picks up.

ClearScale, Onstream partner on IoT intelligence cloud service

ClearScale and Onstream are partnering on an IoT cloud service

Device intelligence automation specialist Onstream is partnering with ClearScale to develop a cloud-based IoT service for smart devices.

Onstream offers a connected device framework that aims to bring data processing closer to the smart devices and sensors generating the data, without having to do much re-coding or bespoke integration between those devices and a centralised repository or application.

The aim of the service is to make device intelligence gathering easier in a distributed infrastructure environment, a need that will likely grow as the volume of data IoT services generate continues to increase.

The companies said the cloud-based implementation of Onstream’s service, called ‘Mesosphere’ (not to be confused with Apache Mesos-based Mesosphere), will allow users to more easily extend the framework to their own customers’ devices.

The service is hosted on AWS infrastructure; ClearScale is an AWS Premier Consulting Partner and has worked with companies like Samsung, Aetna and Shinola Detroit to create its cloud integration platform using Docker, open source Samza data stream processing and Amazon EC2 Container Service.

“Onstream is a very innovative company. They wanted to use the best technology to achieve low latency and fast processing for their new framework,” said Pavel Pragin, chief executive of ClearScale. “Amazon EC2 Container Service (ECS) had just been made generally available, and Onstream was an early adopter. ECS has been instrumental in automating the deployment of Docker containers.”

Ericsson strikes global IoT partnership with SK Holdings

Ericsson and SK Holdings are partnering on IoT

Swedish networking company Ericsson has announced the establishment of a collaboration partnership with Korean tech conglomerate SK Holdings to develop a global ICT ecosystem that will support Ericsson’s IoT platform, reports Telecoms.com.

SK Holdings is the owner of one of Korea’s major operators – SK Telecom – but also has interests a number of other areas of ICT. “Drawing from our strength in ICT services and solutions, we will enhance ICT competitiveness and strengthen our presence in global markets by forging partnerships with leading global companies in the areas of IoT, cloud networks and Big Data,” said Park Jung-ho, CEO of SK Holdings. “We will create a strong collaborative ecosystem with global ICT and solution companies for our global target markets and target industries.”

“Our IoT platform has opened up great opportunities for businesses across industries,” said Ericsson CEO Hans Vestberg. “We look forward to working together with SK Holdings C&C to build a strong ICT ecosystem to realize and capture the benefits of the Networked Society.”

The actual announcement concerned the signing of an ‘extensive memorandum of understanding’ on 12 August. It committed the two companies to jointly develop IoT platforms specialized for certain industries, such as healthcare and transportation. In that sense it seems to be an extension of Ericsson’s recently announced strategy to diversify beyond telecoms. The two companies will also collaborate on other new ICT services, as well as security solutions that encompass both networks and data.

In other IoT partnership news Stream Technologies, which provides the IoT-X platform for managing connected devices, has got together with Link Labs, which specialises in developing LoRa networks, to develop a LoRa IoT platform.

“Link Labs are a perfect partner for deploying LoRa carrier grade LPWA networks,” said Tracy Hopkins, SVP of Low Power Networks for Stream Technologies. “Not only do they support the LoRaWAN open ecosystem and like Stream are active members of the LoRa Alliance, they also have Symphony Link which offers a different feature set for private networks… In this complex ’market of markets’, partnerships that make deployment simple and deliver on the business model are the very key to success.”

“We are very excited to be working with Stream’s IoT-X platform to bridge the gap between Link Labs’ LoRa Symphony Link networks and other IoT and M2M technologies,” said Bryan Eagle, VP of Biz Dev and Marketing at Link Labs. “Having simple, ease of management across multiple networks is a huge benefit for our customers. They deploy different technologies for different applications but want a single platform to manage them and Stream can deliver that.”

Jennifer Kent of Parks Associates on IoT and healthcare

BCN spoke to Jennifer Kent, Director of Research Quality and Product Development at Parks Associates, on the anticipated impact IoT will have on healthcare.

BCN: Can you give us a sense of how big an impact the Internet of Things could have on health in the coming years?

Jennifer KentJennifer Kent: Because the healthcare space has been slow to digitize records and processes, the IoT stands to disrupt healthcare to an even greater extent than will be experienced in other industries. Health systems are just now getting to a point where medical record digitization and electronic communication are resulting in organizational efficiencies.

The wave of new data that will result from the mass connection of medical and consumer health devices to the Internet, as part of the IoT, will give care providers real insight for the first time into patients’ behaviour outside of the office. Parks Associates estimates that the average consumer spends less than 1% of their time interacting with health care providers in care facilities. The rest of consumers’ lives are lived at home and on-the-go, engaging with their families, cooking and eating food, consuming entertainment, exercising, and managing their work lives – all of which impact their health status. The IoT can help care providers bridge the gap with their patients, and can potentially provide insight into the sources of motivation and types of care plans that are most effective for specific individuals.

 

Do you see IoT healthcare as an essentially self-enclosed ecosystem, or one that will touch consumer IoT?

IoT healthcare will absolutely touch consumer IoT, at least in healthcare markets where consumers have some responsibility for healthcare costs, or in markets that tie provider payments to patients’ actual health outcomes. In either scenario, the consumer is motivated to take a greater interest in their own self-care, driving up connected health device and application use. While user-generated data from consumer IoT devices will be less clinically accurate or reliable, this great flood of data still has the potential to result in better outcomes, and health industry players will have an interest in integrating that data with data produced via IoT healthcare sources.

 

Medical data is very well protected – and quite rightly – but how big a challenge is this to the development of effective medical IoT, which after all depends on the ability to effectively share information?

All healthcare markets must have clear regulations that govern health data protection, so that all players can ensure that their IoT programs are in compliance with those regulations. Care providers’ liability concerns, along with the investments in infrastructure that are necessary to protect such data, have created the opportunity for vendors to create solutions that take on the burden of regulatory compliance for their clients. Furthermore, application and device developers on the consumer IoT side that border very closely the medical IoT vertical can seek regulatory approval –even if not required – as a means of attaining premium brand status from consumers and differentiation from the may untested consumer-facing applications on market.

Finally, consumers can be motivated to permit their medical data be shared, for the right incentive. Parks Associates data show that no less than 40% of medical device users in the U.S. would share the data from their devices in order to identify and resolve device problems. About a third of medical devices users in the US would share data from their devices for a discount on health insurance premiums. Effective incentives will vary, depending on each market’s healthcare system, but care providers, device manufacturers, app developers, and others who come into contact with medical device data should investigate whether potential obstacles related to data protection could be circumvented by incentivizing device end-users to permit data sharing.

 

You’re going to be at Internet of Things World Europe (5 – 7 October 2015 Maritim proArte, Berlin). What are you looking forward to discussing there and learning about?

While connected devices have been around for decades, the concept of the Internet of Things – in which connected devices communicate in a meaningful way across silos – is at a very early and formative stage. Industry executives can learn much from their peers and from visionary thinkers at this stage, before winners and losers have been decided, business plans hardened, and innovation slowed. The conversations among attendees at events like Internet of Things World Europe can shape the future and practical implementation of the IoT. I look forward to learning how industry leaders are applying lessons learned from early initiatives across markets and solution types.

Intel, Wipro join IoT, M2M trade body to boost deployments

Intel and Wipro are joining the IMC

Intel and Wipro are joining the IMC

Intel and Wipro have this week joined the International M2M Council (IMC), a global trade association set up to represent Internet of Things vendors and service providers and boost volume IoT deployments.

The trade body, which does advocates on behalf of IoT vendors and service providers, claims to have over 10,000 members and is on track to grow by another 5,000 by the year’s end. In addition to Intel and Wipro companies on the IMC board of governors include Aeris, AT&T, Deutsche Telekom, Digi International, Inmarsat, Iridium, KORE, Nighthawk Controls, Numerex, ORBCOMM, Synapse Wireless, Telecom Italia, Telit, Verizon, and Wyless.

“The IMC’s focus on business results suits our role as a provider of end-to-end IoT solutions very well,” said Vijay Anand V.R., practice director, IoT Business, Wipro Digital, who has also joined the IMC Board

“This trade group also has a truly global footprint that fits our business model and aspirations.”

Rose Schooler, vice president of the IoT Strategy Office at Intel, who also sits on the IMC board of governors said: “The IMC is an industry-leading professional organisation that is reaching out to adopters of IoT technology on a broad scale. The organisation is gaining an average of 275 new members per week – members that are developing, buying, and deploying IoT solutions. Clearly, there is a demand in the market to learn more.”

Both Intel and Wipro have accelerated their IoT efforts over the past few months. Earlier this year enterprise vendor Software AG and outsourcing giant Wipro teamed up to offer a platform for streaming analytics generated by Internet of Things sensors and devices.

Intel has also ramped up its collaborations in the space, teaming with Fujitsu in May this year to develop Internet of Things solutions for manufacturing, retail and public sector clients.

Enabling smart cities with IoT

The Internet of Things will help make cities smarter

The Internet of Things will help make cities smarter

The population of London swells by an additional 10,000 a month, a tendency replicated in cities across the world. To an extent such growth reflects the planet’s burgeoning wider population, and there is even an interesting argument that cities are an efficient way of providing large numbers with their necessary resources. What we know as the ‘smart city’ may well prove to be the necessary means to manage this latest shift at scale.

Justin Anderson is sympathetic to this assessment. As the chairman of Flexeye, vice chair of techUK’s Internet of Things Council, and a leader of government-funded tech consortium Hypercat and London regeneration project Old Oak Common, he is uniquely positioned to comment on the technological development of our urban spaces.

“We are in an early stage of this next period of the evolution of the way that cities are designed and managed,” he says. “The funny thing about ‘smart’ of course, is that if you look back 5000 years, and someone suggested running water would be a good idea, that would be pretty smart at the time. ‘Smart’ is something that’s always just over the horizon, and we’re just going through another phase of what’s just over the horizon.”

There’s some irony in the fact that Anderson finds himself so profoundly involved in laying the foundations for smarter cities, since architects have been in his family for 400 years, and he intended to go in that direction himself before falling into the study of mathematics – which then led to a career in technology.

“There are lots of similarities between the two,” he says. “Stitching lots of complex things together and being able to visualise how the whole thing might be before it exists. And of course the smart city is a world comprised of both the physical and virtual aspects of infrastructure, both of which need to be tied together to be able to manage cities in a more efficient way.”

Like many of the great urban developments, the smart city is mostly going to be something invisible, something we quickly take for granted.

“We’re not necessarily all going to be directly feeling the might of processing power all around us. I think we’ll see a lot of investment on the industrial level coming into the city that’s going to be invisible to the citizen, but ultimately they will benefit because it’s a bit more friction taken out of their world. It’ll be a gradual evolution of things just working better – and that will have a knock on effect of not having to queue for so long, and life just being a little bit easier.”

There are, however, other ways connectivity could change urban life in the coming years: by reversing the process of urban alienation, and allowing online communities to come together and effect real world change.

“If you can engage citizens in part of that process as a way that they live, and make sure that they feel fully accountable for what the city might be, then there’s also a lot of additional satisfaction that could come from being a part of that city, rather than just a pawn in a larger environment where you really have no say and just have to do what you’ve got to do. Look at something like air quality – to be able to start to get that united force and be able to then put more pressure upon the city authorities to do something about it. Local planning policy is absolutely core in all of this.”

Anderson sees technology as an operative part of the trend towards devolution, with cities and their citizens gaining more and more control of their destiny. “If you build that sort of nuclear community around issues rather than just around streets or neighbourhoods, you get new levels of engagement.” For such changes to be effected, however, there is plenty that still needs doing on the technical level – a message Anderson will bringing to Internet of Things World Europe event in Berlin this October.

“I think the most important thing right now is that technology companies come together to agree on a common urban platform that is interoperable, allowing for different components to be used appropriately, and that we don’t find ourselves locked into large systems that mean cities can’t evolve in a flexible and fluid way in the future. We have to have that flexibility designed into this next stage of evolution that comes frMakom interoperability. My drive is to make sure everyone is a believer in interoperability.”

Sixth-sensors: The future of the Internet of Things and the connected business

IT departments will soon have to worry about IoT

IT departments will soon have to worry about IoT

An IT admin walks in to his cabin and instantly knows something is wrong. He does not even have to look at his dashboard to identify the problem. Instead, he heads straight to the server room to fix the server which is overheating because of a failed fan.

The IT admin does not have a sixth-sense. He is alerted to the problem by an internet-enabled thermostat in the server room which sensed the rise in temperature and automatically changed the lighting to alert the admin, through an internet-enabled lightbulb and his smart watch.

This is not the plot of a futuristic Sci-Fi movie. It is 2015 and just one example of how the Internet of Things (IoT) is already at work in business.

Smart living

Every few years, IT communities become awash with new buzzwords and trends that early adopters declare as the next big thing and sceptics decry as impractical and over-hyped. Over time, some fizzle out because of low industry acceptance, while others go on to really disrupt the industry.

From smart cars to watches and even homes, connected technologies are already changing consumer lives, fueling growing expectations and apprehensions. Last year, the government demonstrated its belief in the future potential of technology when it pledged to spend £45m to develop the IoT, more than doubling the funds available to the UK technology firms developing everyday devices that can communicate over the internet.

In the consumer market, IoT technology is already being lapped up. Within just a few months of its launch, Apple claimed 75% of the smartwatch market. As yet, self-driving cars are yet to take to Britain’s roadways. However, with prototypes already being pioneered and app developers racing to create everything from connected entertainment to automated piloting using GPS, when the infrastructure required to make smart cities a reality is sanctioned by local councils and city mayors, IoT could literally find itself in the driving seat.

Smart workplaces

Outside of very early prototype projects, currently, IoT does not rank highly on the enterprise agenda, which is typically a few years behind the general technology adoption cycle. However, in the not-too-distant future, smart-devices will be the norm – IDC estimates the market will be worth $8.9 Trillion by 2020, with 212 billion connected devices.

With the promise of enhanced business processes and intelligence, IoT is increasingly being touted as a holy amalgamation of big data, mobility and cloud technology. Despite this, in the short term at least, businesses will be reluctant to flow of sensitive data through such internet-enabled devices due to obvious security concerns. The exception is in the large businesses that have already explored the potential of machine-to-machine connectivity in their industries, such as automotive and insurance.

Where smart devices are catching up in day-to-day business is in an entirely different function of operations – facilities. What if your management decides to get internet-enabled LED bulbs and thermostats which connect to the internet? Will the IoT bring additional responsibilities on to the service desk? A definite yes.

Facilities need to be managed – and a tool to manage them. That’s just the start. For example, each bulb in a smart IoT connected environment must be monitored and checked to confirm they are working.

Assuming there are over 100 such appliances in an office environment, consider all the IP addresses that will need to be allocated. Likewise, a mesh network would also be required to control the IP address allocation, where one connected device would result in an ad-hoc network.

As previously non-IT facilities start to be connected to the internet, it will be the job of the IT team to make sure they’re working well. As the volume of devices connected to the network grows, securing it will be even more challenging.

Of course, organisations can get around the security challenge by having a local network dedicated only for these devices, but the management of this expanded estate would nonetheless require a dedicated management tool.

Where large organisations have already invested in machine-to-machine (M2M) interactions and deployed connected devices in their facilities, the purpose has typically been to achieve automation and gather more intelligence.

As yet, smaller businesses do not have to worry about automation and logistics at such large scales and it’s clear that the IoT is definitely not going transform their business operations overnight. However, before long, IoT will be something all IT departments should learn to manage – especially the new generation of IoT-connected devices which would traditionally have been classed and managed as non-IT assets.

GE reveals Predix-based cloud for industrial Internet of Things applications

GE is launching a cloud service aimed at industrial IoT

GE is launching a cloud service aimed at industrial IoT

GE has launched a cloud service based on its industrial equipment monitoring and analytics platform, Predix, which it is aiming at industrial IoT applications in most of the verticals it already serves – aviation, manufacturing, automotive, energy and healthcare.

The cloud service will hoover up and analyse data generated by IoT sensors embedded in industrial equipment and can use the insights to optimise operations and proactively manage the equipment’s health by suggesting tailored maintenance regimes, whether an energy infrastructure asset or a jet engine.

While GE has offered these kinds of services for years this is the first time it has decided to offer them directly via the cloud to customers. The company is pitching Predix as an on-demand “cloud platform for the industrial internet.”

“Cloud computing has enabled incredible innovation across the consumer world. With Predix Cloud, GE is providing a new level of service and results across the industrial world,” said Jeffrey Immelt, chief executive of GE.

“A more digital hospital means better, faster healthcare. A more digital manufacturing plant means more products are made faster. A more digital oil company means better asset management and more productivity at every well. We look forward to partnering with our customers to develop customized solutions that will help transform their business,” he said.

The service includes a range of tools to help customers manage security, compliance and data governance, and GE claims that it can integrate seamless with other services running in on a broad range of cloud platforms.

“A cloud built exclusively to capture and analyse machine data will make unforeseen problems and missed opportunities increasingly a complication of the past,” said Harel Kodesh, vice president, general manager of Predix at GE Software. “GE’s Predix Cloud will unlock an industrial app economy that delivers more value to machines, fleets and factories – and enable a thriving developer community to collaborate and rapidly deploy industrial applications in a highly protected environment.”

The reveal comes less than a month after what was effectively a softer Predix launch. In July GE announced it is partnering with Pitney Bowes to develop a custom asset performance management (APM) application that analyses the data Pitney Bowes generates from its production mailing and shipping machines to improve the efficiency of its equipment. That partnership saw the companies adapt GE’s Predix software analytics platform to its mail handing and shipping environment.

Both companies have already partnered with one another elsewhere in the IoT ecosystem. Pitney Bowes and GE are members of the Industrial Internet Consortium, a membership group of telcos, research institutes and technology manufacturers formed last year and focused on developing interoperability standards and common architectures to bridge smart devices, machines, mobile devices and the data they create.

Lighting and the Internet of Things

Philips is experimenting with using connected lights to for everything from keeping us abreast of important messages to making video games more interactive and impactful on our senses

Philips is experimenting with using connected lights to for everything from keeping us abreast of important messages to making video games more interactive and impactful on our senses

When was the last time you thought about your lights? Whether you are outside or in, you will probably see 4, 5 or more sources of artificial light within view. There is an estimated 50 billion individual light points in the world today – seven or so per person; of all technology, the light bulb is arguably the most ubiquitous.

It is perhaps because of this ubiquity that light has all but disappeared from our conscious minds. We utilise it with minimal thought, though sometimes its complexities are impossible to ignore. If we were preparing a romantic dinner, for instance, we would tailor the lighting accordingly. We do this because lighting doesn’t merely reflect mood, but dictates it, something connectivity is increasingly enabling us to take advantage of.

“We’ve evolved for the last however many millions of years to expect light from the sun,” says George Yianni, head of technology at Philips Lighting Home Systems. “If there’s a bright, cool white light at midday from the sun, our brain is hardwired to be awake and alert. If there is a very warm dim light such as you get around sunset, our brain is hardwired to start winding down and relaxing.”

Yianni is a technological evangelist. In a very literal way he has seen the light, and he wants to harness this physiological sensitivity to light (among other responses) to help us to relax, to deal with jet lag, to concentrate better and much more. Due to the degree to which we take lighting for granted, however, it’s an area that poses obvious challenges to innovators:  “As a consumer, the only time you think about a light bulb inside your house is when one breaks and you have to try to find one that fits in the same socket and gives the same light output. But actually it is amazing how light can transform how a space looks, how you feel in a space.”

One of the first projects Yianni was involved in was the use of tunable white light in some German schools, giving teachers the ability to modify the lighting by changing the colour temperature, to calm students down, help them wake up, or enhance concentration (Yanni says their test scores improved significantly as a result). It was after working on a succession of such projects – including outdoor street lighting, office lighting, football stadiums, and more – that he accepted the challenge of introducing these kinds of effects and improvements into the home in the form of Philips Hue connected lighting for the home. “I wanted to make this kind of lighting accessible, understandable and impactful for normal people. I wanted people to think about lighting more than just when it’s broken.”

Some of the results and available use cases will be familiar to anyone with an eye open to contemporary commercial IoT. Lighting that knows when you’ve come home, for example, and can ensure that you don’t step into a dark, inhospitable house after a trip or long day at work. By the same token, remotely controllable or programmable lighting that can give people added peace of mind when they’re away – by making it look like they’re not.

Familiar as this latter use case might be, it also points towards another intriguing capacity of lighting. Usually, we turn lighting on and off according to whether we need it: but a house burglar may translate this as whether we are at home or out. Far from being oblivious to lighting, lighting speaks volumes to would-be burglars.

The potential of lighting to communicate in other, less nefarious contexts is something Phillips is encouraging its customers to exploit.

“We’re enabling people to use Philips Hue lights inside their homes and by extension the homes themselves to communicate simple notifications,” says Yianni. “So, in the morning, if the Philips Hue light in your porch is blue you know it’s going to rain that day, if it’s yellow you know it’s not so you can plan whether to bring a umbrella or not. Other customers are using Philips Hue lights to notify them about important email messages. There’s a wide range of way where people are actually using connected lighting in their homes to keep them informed in a less distracting way than an alarm or a buzzer.”

Another popular use case for smarter lighting concerns home entertainment. Whether we’re watching movies or TV, playing video games, or listening to music, Philips Hue is unique in that it can greatly enhance the experience through more than 300 third-party apps. Philips Hue launched the first video game, movies and TV shows with ‘scripted’ lighting programmed by the content creators to sync with their lights delivering a more immersive experience in the home. Yianni provides some examples: “As your health is dropping down in the video game Chariot, the Philips Hue lights turn red in your lounge. As a protagonist enters a dark cave in a movie, the Philips Hue lights will dim down.”

“For the last hundred years, people have been used to expecting nothing more on and off from a light bulb,” says Yianni. “We are changing that.”

In September Yianni will be appearing at Internet of Things World Europe in Berlin, where he’ll be using lighting to really illuminate the potential for IoT to revolutionise some of the most fundamental and taken-for-granted details of our day-to-day lives, as well as the central importance of communicating this to consumers. 

NTT Com sets up IoT practice

NTT Com is setting up an IoT practice

NTT Com is setting up an office to target the development, sales and marketing of Internet of Things solutions.

The ICT-focused subsidiary of NTT Group said it will leverage its expertise in cloud computing, software development and telecoms to design and sell IoT solutions to clients, solutions that make use of the company’s 130 cloud datacentres and global network.

It plans to offer a one-stop application platform that can store, analyse and visualise data generated from IoT sensors.

The company is already working with a number of companies in Japan and Indonesia on a series of IoT trials.

In August this year for instance it announced a partnership with Kanazawa Nishi Hospital in Japan to test sensors deployed in electric appliances to help monitor elderly people living alone. In April it announced a partnership with TOCHU Corporation to test a smart streetlighting network at a complex in Indonesia to help optimise power consumption.
