• Docker Doubles Down on Microsoft Windows Server [Ed: recall "DockerCon 2015 Infiltrated by Microsoft"]

  Docker for Windows debuts alongside a new commercial support relationship with Microsoft. For the most part, the Docker container phenomenon has been about Linux, with the majority of all deployments on Linux servers. But that could soon be changing as Docker Inc. today is announcing the general availability of Docker Engine on Windows Server 2016, alongside a new commercial support and distribution agreement with Microsoft. Docker containers rely on the host operating system for certain isolation and process elements in order to run. On Linux, those elements have always been present as part of the operating system, but the same was not true for Windows, which has required several years of joint engineering effort between Docker Inc. and Microsoft.

• Hadoop Sandboxes and Trials Spread Out

  We all know that there is a skills gap when it comes to Hadoop in the Big Data market. In fact, Gartner Inc.'s 2015 Hadoop Adoption Study, involving 284 Gartner Research Circle members, found that only 125 respondents who completed the whole survey had already invested in Hadoop or had plans to do so within the next two years. The study found that there are difficulties in implementing Hadoop, including hardship in finding skilled Hadoop professionals.

• Use models to measure cloud performance

  When I was young, I made three plastic models. One was of a car—a '57 Chevy. Another was of a plane—a Spitfire. And a third was of the Darth Vader TIE Fighter. I was so proud of them. Each one was just like the real thing. The wheels turned on the car, and the plane’s propeller moved when you blew on it. And of course, the TIE Fighter had Darth Vader inside. When I went to work on the internet, I had to measure things. As I discussed in my last post, Measure cloud performance like a customer, when you measure on the internet you need to measure in ways that are representative of your customers’ experiences. This affects how you measure in two ways. The first is the perspective you take when measuring, which I talked about last time. The second way is the techniques you use to perform those measurements. And those techniques are, in effect, how you make a model of what you want to know. Those childhood plastic models turn out to offer some solid guidance after all.

• ODPi Adds Apache Hive to Runtime Specification 2.0

  Today, ODPi announced that the ODPi Runtime Specification 2.0 will add Apache Hive and Hadoop Compatible File System support (HCFS). These components join YARN, MapReduce and HDFS from ODPi Runtime Specification 1.0 With the addition of Apache Hive to the Runtime specification, I thought it would be a good time to share why we added Apache Hive and how we are strategically expanding the Runtime specification.

• Ubuntu’s OpenStack on IBM’s Big Iron

  If I were Red Hat I would be looking over my shoulder right now; it appears that Ubuntu might be gaining. In just a few years the Linux distribution has gone from being non-existent in the enterprise to being a powerhouse. This is especially true in the cloud, where it's a dominant force on both sides of the aisle. Not only is it the most deployed operating system on public clouds, its version of OpenStack accounts for over half of OpenStack cloud deployments, used by the likes of Deutsche Telekom, Bloomberg and Time Warner Cable.

• Strategies for Running Stateful Applications in Kubernetes: Volumes

  Mesosphere DC/OS emphasizes running transactional workloads alongside cloud-native applications. Robin Systems, one of the container management companies, is aiming to containerize Oracle and other enterprise databases. The Kubernetes container orchestration engine is gearing up to run stateful workloads through a new concept called Pet Sets, which is a pod of stateful containers. Pet Sets was introduced as an alpha feature in Kubernetes 1.3, released in July. Kubernetes abstracts the underlying infrastructure building blocks into compute, storage and networking. When developers and operations teams get started with Kubernetes, they typically get exposed to objects such as pods, labels, services, deployments and replica sets, which provide a mechanism to deal with compute and networking. When it comes to persistence in Kubernetes, users should get familiar with the concepts of volumes, persistent volumes, persistent volume claims (PVC) and the upcoming Pet Sets. This article will be a first in a series that discusses the strategies and use cases for each of the storage choices available in Kubernetes. In this chapter, we will take a closer look at volumes, that provide the easiest migration path to Kubernetes.

Ubuntu 16.10 Final Beta Officially Released with Linux Kernel 4.8, Download Now

Delayed six days, the Final Beta release of the upcoming Ubuntu 16.10 (Yakkety Yak) operating system launched today, September 28, 2016, as the final development snapshot in the series. Today's Final Beta is in fact the first Beta pre-release version of Ubuntu 16.10, and the only development milestone that you'll be able to test if you want to see what's coming to the next major release of Ubuntu Linux. However, we can tell you that it is powered by Linux kernel 4.8, contains up-to-date applications, and still uses the Unity 7 UI.

Parsix GNU/Linux 8.5 "Atticus" to Reach End of Life on September 30, 2016

The Parsix GNU/Linux developers announced that the end-of-life status is approaching fast for the Parsix GNU/Linux 8.5 "Atticus" operating system, urging users to upgrade to the latest release immediately. Dubbed Atticus and based on the Debian GNU/Linux 8.5 "Jessie" operating system, Parsix GNU/Linux 8.5 was unveiled seven months ago, on February 14, 2016. Running the long-term supported Linux 4.1.17 kernel injected with TuxOnIce 3.3 and BFS patches, it was built around the GNOME 3.18 desktop environment with the GNOME Shell 3.18.3 user interface. The end of life (EOL) will be officially reached on September 30, 2016, which means that users of the Parsix GNU/Linux 8.5 "Atticus" operating system will no longer receive security and software updates. Therefore, they are urged today to upgrade to the latest, most recent version of the Debian-based distribution, Parsix GNU/Linux 8.10 "Erik."
