Exponential Docker usage shows container popularity

Global Container TradeAdoption of Docker’s containerisation technology has entered a period of explosive growth with its usage numbers nearly doubling in the last three months, according to its latest figures.

A declaration on the company blog reports that Docker has now issued 2 billion ‘pulls’ of images. In November 2015 the usage figure stood at 1.2 bullion pulls and the Docker Hub from which these images are pulled was only launched in March 2013.

Docker’s invention of software defined autonomous complete file system that encapsulates all the elements of a server in microcosm – such as code, runtime, system tools and system libraries – has whetted the appetite of developers in the age of the cloud.

In January 2016, Docker users pulled images nearly 7,000 times per minute, which was four times the run rate a year ago. In that one month Docker enjoyed the equivalent of 15% of its total transaction from the past three years.

The number of ‘pulls’ is significant because each of these transactions indicates that a Docker engine is downloading an image to create containers from it. Development teams use Docker Hub to publish and use containerised software, and automate their delivery. The fact that two billion pulls have now taken place indicates the popularity of the technology and the exponential growth rate in the last three months is an indicator of the growing popularity of this variation of virtualisation.

There are currently over 400,000 registered users on Docker Hub. “Our users span from the largest corporations, to newly-launched startups, to the individual Docker enthusiast and their number is increasing every day,” wrote Docker spokesman and blog author Mario Ponticello.

Around a fifth of Docker’s two billion pulls come from its 93 ‘Official Repos’ – a curated set of images from Docker’s partners, including NGINX, Oracle, Node.js and Cloudbees. Docker’s security-monitoring service Nautilus maintains integrity of the Official Repos over time.

“As our ecosystem grows, we’ll be adding single-click deployment and security scanning to the Docker platform,” said Monticello.

A Rightscale study in January 2016 found that 17% of enterprises now have more than 1,000 virtual machines in the public cloud (up 4% in a year) while private clouds are showing even stronger appetite for virtualisation techniques with 31% of enterprises running more than 1,000 VMs, up from 22% in 2015.

ElasticHosts launches elastic containers – could cut some running costs by 50%

containersCloud server company ElasticHosts has announced its new model of container technology can adapt automatically to fit volatile shifts in demand for resource and bill clients accordingly. The new Linux containers are designed to make management easier for resellers, service providers, web developers and web hosting companies.

ElasticHosts’ new containers are now available with cPanel v11.52, from third party control panel vendor cPanel. ElasticHosts claims it offers the first containers to integrate with cPanel v11.52, which now creates the possibility for much more precise billing according to the usage of server resources such as memory, processing power and storage. It also gives service providers the option to automatically adapt to changing circumstances, so clients only ever have to pay for what they use while there is no risk of hitting a performance barrier in periods of intense activity.

The control panel from cPanel can streamline the process of creating and managing websites, claims its vendor. Prior to the new release cPanel could only run on virtual machine servers with licensing according to the virtual private server (VPS) model. The new ability to ‘autoscale’ and the capacity for exact billing will lower costs for clients, according to ElasticHosts. The usage-based billing offered by containers means website owners no longer have to pay for periods when server capacity is underutilised or the site is idle, typically saving up to 50% on hosting costs, it claims.

“We worked closely with cPanel integrating and testing the product to make this a reality and believe our technologies complement each other well,” said ElasticHosts CEO Richard Davies, “containers are gaining real momentum.”

“Linux containers are an exciting technology and we have recognized the groundswell behind them in the internet community right now,” said Aaron Phillips, Chief Business Officer at cPanel.

AT&T, Ericsson and Apcera demonstrate NFV in a PaaS environment

Voice and video can work in the most complicated clouds, according to an integration breakthrough demonstrated at the OpenStack summit in Tokyo.

AT&T and Ericsson claim they’ve created an improvement to container technology that makes cloud telco platforms far more secure and yet easier to set up. They jointly presented their invention in proof of concept exercise, along with cloud service provider Apcera.

Container technology, previously used for creating secure environments for text based office and enterprise productivity applications, has been tweaked in order to overcome some of its security limitations, when telecoms is handled in the cloud.

Telco AT&T, equipment maker Ericsson and cloud service provider Apcera described how they came together in order to bring their own perspectives of the multiple levels of the OpenStack hierarchy. The joint problem they faced is that the virtualization of telecoms still has some teething problems that need to be resolved, such as the interaction of various web browsers and video and audio services.

The companies demonstrated how they have tweaked container technology to create a containerised policy driven PaaS that can use the telecoms related Virtualized Network Function (VNF). The resulting telecoms-charged ‘advanced container’ was able to house a Web Communication Gateway (vWCG) that fully integrated with OpenStack.

The proof of concept exercise showed audio and video communications actually worked between multiple Web browsers on the virtualized telephony system.

Never mind the complexity of what’s happening across the comms stack and the cloud, the main thing to take home is that this system works with a few clicks of a mouse, said Magnus Arildsson, Head of IaaS and PaaS at Ericsson. “This is an important step toward fast, secure and policy-integrated deployment of Telco VNFs on micro-services-based containers,” he said.

Ericsson and Apcera accelerated the development of the micro-services-based PaaS environment, said Derek Collison, CEO of Apcera. “This exercise paves the way for cost-effective, efficient deployments and further collaboration with telco operators to integrate carrier-grade requirements with our cloud platform.”
