Platform-as-a-Service (PaaS) is a technology designed to make DevOps easier and allow developers to focus on application development. The PaaS takes care of provisioning, scaling, HA, and other cloud management aspects. Apache Stratos is a PaaS codebase developed in Apache and designed to create a highly productive developer environment while also supporting powerful deployment options.
Integration with the Docker platform, CoreOS Linux distribution, and Kubernetes container management system brings more scalability and flexibility to Apache Stratos PaaS.
In his session at 15th Cloud Expo, Lakmal Warusawithana, Director of Cloud Architecture at WSO2 Inc., will discuss installing and deploying sample applications using Docker, CoreOS and Kubernetes, and walkthrough how it can be extended to support new application containers. He will also demonstrate app deployment, provisioning, auto-scaling, and more.

As IT professionals we have been overwhelmed with different standards for each component of architecture, service delivery, governance, security, and operations. Not only does IT need to ensure technical training and certification, but it is also desired to pursue certifications in ITIL, TOGAF, COBIT, PMP, and a variety of other frameworks – at a high cost in both time and money.

When an enterprise builds a hybrid IaaS cloud connecting its data center to one or more public clouds, security is often a major topic along with the other challenges involved. Security is closely intertwined with the networking choices made for the hybrid cloud.
Traditional networking approaches for building a hybrid cloud try to kludge together the enterprise infrastructure with the public cloud. Consequently this approach requires risky, deep “surgery” including changes to firewalls, subnets and other modifications to the corporate security infrastructure. Connecting a public cloud to the enterprise requires infrastructure changes to limit how deep into the enterprise it can see. For those who have dealt with it, it’s time consuming and risky, requiring a complete InfoSec review of the new structure. More important, even if an enterprise does it once successfully, it has to be repeated for each new project and cloud service provider.

Technology is enabling a new approach to collecting and using data. This approach, commonly referred to as the “Internet of Things” (IoT), enables businesses to use real-time data from all sorts of things including machines, devices and sensors to make better decisions, improve customer service, and lower the risk in the creation of new revenue opportunities.
In his General Session at Internet of @ThingsExpo, Dave Wagstaff, Vice President and Chief Architect at BSQUARE Corporation, discuss the real benefits to focus on, how to understand the requirements of a successful solution, the flow of data, and how to best approach deploying an IoT solution that will drive results.

Cryptography has become one of the most underappreciated, misunderstood components of technology. It’s too easy for salespeople to dismiss concerns with three letters that nobody wants to question. ‘Yes, of course, we use AES.’
But what exactly are you trusting to be the ultimate guardian of your data? Let’s face it – you probably don’t know. An organic, grass-fed Kobe steak is a far cry from a Big Mac, but they’re both beef, right? Not exactly. Crypto is the same way. The US government requires all federally deployed technology to meet minimum standards. For encryption, if it hasn’t been certified to meet the FIPS 140-2 benchmark, it is considered the equivalent of exposing your data in plain text. That’s how crucial it is.

Over the years Function Points have been a most scientific method of measuring the size of business capability. The main reason is that function point is technology agnostic and counts the output directly from the point of view of business user. So at the end of day any gain in the served function point of an application means an increased business capability.

Typically delivering function points comes at cost of certain number of code, typically for example if you deliver one function point this may cost an organization some 70 odd lines of code and the associated cost of development and effort.

Most organization have some level of bench mark of the typical lines of code they produce to delivery one function point.

In the consumer IoT, everything is new, and the IT world of bits and bytes holds sway. But industrial and commercial realms encompass operational technology (OT) that has been around for 25 or 50 years. This grittier, pre-IP, more hands-on world has much to gain from Industrial IoT (IIoT) applications and principles. But adding sensors and wireless connectivity won’t work in environments that demand unwavering reliability and performance.
In his session at @ThingsExpo, Ron Sege, CEO of Echelon, will discuss how as enterprise IT embraces other IoT-related technology trends, enterprises with industrial or commercial facets must also find ways for the disparate worlds of OT and IT to work together harmoniously.

The O’Reilly Software Architecture Conference, March 16–19, 2015, Boston, MA, is a new event designed to provide the in-depth professional training that software architects and aspiring software architects need to succeed. A unique event, it covers the full scope of a software architect’s job, from IT to leadership and business skills. It also provides a forum for networking and hearing what other professionals have learned in real-world experiences.
Software architecture is a massive multidisciplinary subject, covering many roles and responsibilities, which makes it challenging to teach because so much context is required for every subject. It’s also a fast-moving discipline, where entire suites of best practices become obsolete overnight.

2014 was an extremely busy year for cloud computing, as more and more businesses migrate and cloud increasingly becomes the de facto setting for IT. The competition between vendors for infrastructure as a service continued ferociously, with Microsoft and IBM cutting back some of AWS’ market dominance.

Before we look at what might happen in 2015, here’s a quick reminder of the main events and highlights from 2014:

Cloud in 2014

March: IBM rebrands as a cloud-first company, lays out its strategy. 2014 has been a year of turbulence and change for the large legacy tech vendors. IBM announced it was to push $1bn of its resources into cloud and that it was rebranding as a cloud company. Rival companies also gave it the big one this year; SAP, for example, made frequent overtures about its ambition to become ‘THE’ cloud company.

April: Microsoft forced to hand over data stored on overseas server. A court in New York ruled against Redmond, after the tech giant resisted a US government warrant demanding access to emails stored on its Dublin server. Whilst bad news for Microsoft, it also raised alarm bells for any company that employs a US cloud provider – their data could be searched and taken at any given moment.

June/July: Code Spaces ceases trading after DDoS attack, Autotask suffers serious outage. Web-based SVN and Git hosting provider Code Spaces waved the white flag after a devastating denial of service attack, while two weeks later CRM provider Autotask went down after a capacity spike. CloudTech secured an exclusive chat with VP engineering Adam Stewart, who admitted this was the worst outage the company had suffered.

August: 4chan users leak private photos of celebrities from iCloud devices. Personal photos of celebrities including Jennifer Lawrence, Kate Upton and Mary Elizabeth Winstead, many featuring nudity, were leaked after being obtained from iCloud. Apple later reported that the victims’ accounts “were compromised by a very targeted attack on user names, passwords and security questions.”

October: IBM and SAP announce partnership for HANA Enterprise Cloud. IBM and SAP, who have had a fruitful partner relationship for over 40 years, announced a major partnership with SAP HANA Enterprise Cloud being delivered through IBM, allowing users the choice to run SAP’s HANA in-memory database either across SoftLayer or IBM’s cloud managed services.

October: Microsoft announces unlimited cloud storage to Office 365 subscribers, Bitcasa removes its unlimited option. The same week saw two companies arrive at two different strategies, leaving wide ranging consequences in the cloud storage wars. Back in June, Microsoft gave each Office 365 user 1TB of storage, but Bitcasa’s move may be for the best – cloud storage and enterprise file and sync is a hot market, and differentiation may be key.

Analysing the 2014 outlook

CloudTech looked at three areas of focus back in December 2013; hybrid cloud, PaaS, and Amazon Web Services. So what did we get right, and what fell wide of the mark?

Hybrid cloud: Hit. As 2013 was the year when hybrid cloud came of age, 2014 was going to be a continuation on this theme. “Public cloud offers cost and scale benefits, while private cloud provides security and control,” commented Len Padilla, VP product strategy at NTT Europe. “Businesses need them both.”

As 2014 drew to a close, there were a glut of stories which proved this point. Back in October a survey found more than half of attendees at the 2014 Cloud Expo and AWS Summit were adopting hybrid cloud strategies, while recent IDC figures put the global cloud market at $118bn for 2015, fuelled by enterprise interest in the hybrid cloud.

It’s not that simple however. Has hybrid cloud hit the mainstream? Not yet. A recent survey by Avanade found that while companies believe more than half of their applications and services will be deployed on the hybrid cloud within three years on average, many are confused about what hybrid actually is and how they have to shape up to prepare for implementation.

PaaS: Hit. Platform as a service was considered a key area for 2014, with organisations demanding their cloud partners offer it to create solutions to make their customer journey unique.

The majority of headlines last year were with IBM after the company rolled out its dedicated BlueMix developer platform, although there were other launches, notably Heroku launching Performance Dynos in Europe. Increasingly companies are looking at agile application development, and this is borne out in the popularity of Node.js and JSON.

It’s not been a completely smooth ride, however. CloudBees announced it was dropping its PaaS operation to focus exclusively on Jenkins back in September, while there have also been discussions about XaaS (everything as a service) and the dissolution of traditional cloud service models.

AWS’ dominance in IaaS: Miss. CloudTech predicted Amazon Web Services would maintain “huge dominance” in the IaaS space through 2014 after analyst figures showed the company’s revenue growth continued to be greater than its four biggest rivals put together.

Things changed a bit last year, although AWS continues to be the significant market leader. Q214 figures from Synergy Research showed Microsoft take the clear second place in the market, growing 164% year on year. IBM grew 86%, Google grew 49% while AWS, by contrast, grew 49%.

Synergy chief analyst John Dinsdale told CloudTech at the time it was just a blip, saying: “I do not think that Amazon is resting on its laurels – quite the opposite actually.” In October, the firm released figures which continued to back up Microsoft’s position as clear second place.

Cloud in 2015?

So what does 2015 have in store? Here are a few predictions from cloud experts:

Cost will no longer be the biggest determiner for choosing a cloud solution. John Engates, CTO at Rackspace, believes value for customers won’t just be about cost in 2015. “While providers will become more agnostic, the importance of a trusted partner will grow stronger, whether you rely on that partner to manage your public or private cloud, automate your DevOps or keep tabs on your apps,” he says.

“Companies will have to ask themselves if they want to swell their payrolls hiring the resources needed to manage all of their tools and technologies. This will force companies to determine what matters most to them – focusing on IT management or their business.”

Greater emphasis on agile development processes. Allan Leinwand, VP and CTO cloud platform and infrastructure at ServiceNow, sees cloud platforms as an important way for business teams to convert ideas into applications. “By having a common platform to develop on, organisations can let their teams rapidly create and test their ideas – in days or weeks, instead of months,” he explains. “They can fail quickly – investing and risking less money. Think of the cloud platform as enabling the ‘series A’ investor within the enterprise.”

IaaS in transition. Nigel Beighton, VP technology at Rackspace, sees infrastructure as a service becoming subordinated as containers, SaaS, PaaS, and continuous deployment continue to rise. “IaaS has spelled its own irrelevance in the mind of the buyer by its API, and the abstractions on top of that which bring value to the user,” he explains.

Enterprises will design private cloud services – with a hybrid future in mind. Sachin Sony is marketing field development manager at Equinix. He sees more successful private and public cloud implementations taking shape in 2015. “2014 was expected to be a year of explosive growth in cloud service consumption,” he explains. “Major cloud providers have become more aggressive in deploying their services, and enterprise CIOs have largely moved beyond simply deploying selected applications in the cloud.

“Yet the private or public cloud debate continues to bubble under the surface. In 2015, this debate will finally be put to bed.”

What do you think will be the main trends in cloud computing this year?
