Due to interest from that, here is a larger selection of cloud instance types from the leading public clouds of Amazon Elastic Compute Cloud, Microsoft Azure, and Google Compute Engine.

  • IBM's Phil Estes on the Turbulent Waters of Container History

    Phil Estes painted a different picture of container history at Open Source 101 in Raleigh last weekend, speaking from the perspective of someone who had a front row seat. To hear him tell it, this rise and success is a story filled with intrigue, and enough drama to keep a daytime soap opera going for a season or two.

  • Red Hat CSA Mike Bursell on 'managed degradation' and open data

    As part of Red Hat's CTO office chief security architect Mike Bursell has to be informed of security threats past, present and yet to come – as many as 10 years into the future.

    The open source company has access to a wealth of customers in verticals including health, finance, defence, the public sector and more. So how do these insights inform the company's understanding of the future threat landscape?

Why open source could be IBM's key to future success in the cloud

Do those same developers need IBM? Developers certainly benefit from IBM's investments in open source, but it's not as clear that those same developers have much to gain from IBM's cloud. Google, for example, has done a stellar job open sourcing code like TensorFlow and Kubernetes that feeds naturally into running related workloads on Google Cloud Platform. Aside from touting its Java bonafides, however, IBM has yet to demonstrate that developers get significant benefits for modern workloads on its cloud.

That's IBM's big challenge: Translating its open source expertise into real, differentiated value for developers on its cloud.

Amazon Linux 2 - Who nicked my cheese?

Filed under

Linux

So far, it's a relatively benign, easy introduction to a new operating system that blends the familiar and new in a timid package. Perhaps that's the goal, because a radical offering would right away scare everyone. Amazon Linux 2 is an appealing concept, as it gives users what Red Hat never quite did (yet) - A Fedora-like bleeding-edge tech with the stability and long-term support of the mainstay enterprise offering. But then, it also pulls a Debian/Ubuntu stunt by breaking ABI, so it will be cubicle to those who enjoying living la vida loco (in their cubicle or open-space prison).

Having lived and breathed the large-scale HPC world for many years, I am quite piqued to see how this will evolve. Performance, stability and ease of use will be my primary concerns. Then, is it possible to hook up a remote virtual machine into the EC2 hive? That's another experiment, and I'd like to see if scaling and deployment works well over distributed networks. Either way, even if nothing comes out of it, Amazon Linux 2 is a nice start to a possibly great adventure. Or yet another offspring in the fragmented family we call Linux. Time will tell. Off you go. Cloud away.

  • iRODS Consortium Carries Open Source Data Management Software Forward

    Integrated Rule-Oriented Data System (iRODS) is used across the globe in industries ranging from the life and physical sciences to media and entertainment, but the software’s origins can be traced back over two decades to a team at the San Diego Supercomputer Center (SDSC) and a project known as the Storage Resource Broker (SRB).

  • ArangoDB Publishes Industry-Wide Open Source NoSQL Performance Benchmark

    ArangoDB, a leading provider of native multi-model NoSQL database solutions, today announced the latest findings of its open source NoSQL performance benchmark series. To enable vendors to respond to the results and contribute improvements, ArangoDB has published the necessary scripts required to repeat the benchmark. The goal of the benchmark is to measure the performance of each database system when there is no cache used. The benchmark is completely open source and therefore driven by community input.

  • Altibase goes open source, says it ‘directly challenges’ Microsoft, IBM and Oracle

    Following the recent announcement that the global software firm is open source, Altibase says it “directly challenges” the other companies by providing equal functionality at a much lower cost. Customers will save money by not having to buy in-memory and disk-resident databases separately, says Altibase. It can easily replace or supplement Oracle as well.

  • Kubernetes Monitoring with Prometheus

    Kubernetes makes management of complex environments easy, but to ensure availability it's crucial to have operational insight into the Kubernetes components and all applications running on the cluster. I believe monitoring is the backbone of a good production environment.

    Applications running in containers and orchestrated by Kubernetes are highly automated and dynamic, and so, when it comes to monitoring applications in these environments, traditional server-based monitoring tools designed for static services are not sufficient.

  • CNCF’s Vitess Scales MySQL with the Help of Kubernetes

    A technology developed by YouTube to shard large MySQL databases across multiple servers, Vitess, has become the 16th hosted project of the Cloud Native Computing Foundation.

    Vitess was created for “people who love MySQL for its functionality, but have chosen not to use it because it does not scale well,” said Sugu Sougoumarane, one of the creators of Vitess who is now co-founder and chief technology officer at PlanetScale Data, a still-stealth startup centered around Vitess, in an interview with The New Stack.

  • Deepfence Emerges from Stealth with Container Security Platform

    Sandeep Lahane has been been quietly building his container security startup Deepfence since 2016. On Feb. 13, Deepfence emerged from its stealth mode, announcing the company's Security as a Microservice technology for container security.

    The Deepfence approach uses what the company refers to a a lightweight sidecar container, which runs alongside an organization's existing Docker and Kubernetes container deployments. Deepfence's technology makes use of artificial intelligence (AI) as well as policy driven rules, to help detect potential threats and enforce workload isolation.

  • What is Software Defined Storage?

    Software defined storage (SDS) decouples storage software from the underlying storage devices. It does this by creating a virtualized software management layer that operates above the storage hardware.

    While that definition may reasonably straight forward, many players in the data storage industry debate the specifics and details of what, exactly, is the true definition of SDS.

  • Your DevOps attempt will fail without these 7 departments buying in

    When DevOps was coined by Andrew Shafer and Patrick Debois, the goal was to bring developers and operators closer to achieve customer value together. DevOps is a culture of continuous learning and improvement. While automation and tools can garner some improvements, having the right culture drives larger impacts. The sharing of knowledge and ideas resulting in cultural growth is the value creator in DevOps.

  • Kubernetes The Smart Way

    Kelsey Hightower, Developer Advocate at Google, kicked off the KubeCon + CloudNativeCon event in Austin with an opening keynote in which he demonstrated Kubernetes' ease of use with the help of his smartphone. Apart from commending the audience for making Kubernetes the boring-in-a-good-way framework it is today, Hightower also warned about how Kubernetes should not be considered the end game, but a means to an end.

    In his talk, Hightower first addressed the misconception that Kubernetes is difficult to install. He did so by installing an eight-node Kubernetes cluster in less than two minutes just by giving verbal instructions to the Kubernetes Engine assistant through his smartphone, thus proving tha Kubernetes generally gets out of the way quickly.

  • Apache CloudStack 4.11 Boosts Open-Source Cloud Features

    Apache CloudStack v4.11 was officially released by the open-source Apache Software Foundation (ASF) on Feb. 12, after eight months of development.

    "This release has been driven by the people operating CloudStack clouds," Rohit Yadav, Apache CloudStack v4.11 Release Manager stated. "Along with great new features, v4.11 brings several important structural changes such as better support for systemd and Java 8, migration to embedded Jetty, and a new and optimized Debian 9 based systemvm template."

    CloudStack has been part of the ASF since April 2012, when Citrix donated the technology to the open-source foundation. Citrix had originally acquired from cloud.com in July 2011. The first official Apache CloudStack release was version 4.0 which debuted in November 2012.

  • The full-time job of keeping up with Kubernetes

    TL;DR - Unabated 1.xx major “minor” releases of “vanilla” upstream Kubernetes every three months could continue forever. You have to keep up, while also paying close attention to Kubernetes API object versioning. This relentless pace is the key ingredient in Kubernetes’ domination of the distributed infrastructure world.

  • Correctly integrating containers

    Kubernetes supports different ways of making containers and microservices contact each other, from connections with the hardware in the data center to the configuration of load balancers. To ensure communication, the Kubernetes network model does not use Network Address Translation (NAT). All containers receive an IP address for communication with nodes and with each other, without the use of NAT.

    Therefore, you cannot simply set up two Docker hosts with Kubernetes: The network is a distinct layer that you need to configure for Kubernetes. Several solutions currently undergoing rapid development, like Kubernetes itself, are candidates for this job. In addition to bandwidth and latency, integration with existing solutions and security also play a central role. Kubernetes pulls out all stops with the protocols and solutions implemented in Linux.

GNOME Shell vs. KDE Plasma Graphics Tests On Wayland vs. X.Org Server

A premium member this week had requested some benchmarks of openSUSE Tumbleweed when looking at the performance of KDE Plasma vs. GNOME Shell in some open-source graphics/gaming tests while also looking at the Wayland vs. X.Org Server performance. With KDE Plasma 5.12 that openSUSE Tumbleweed has picked up, there is much better Wayland session support compared to previous releases. While KDE developers aren't yet ready to declare their Wayland session the default, in my experience so far it's been working out very well but still routinely will find application crashes in Kate and the like when testing under the KWin's Wayland compositor.
