Servers: "Docker Not Doomed?" and Some IBM/Red Hat Leftovers

  • Docker Not Doomed?

    Modern application development essentially consists of composing an application from a variety of services. These services aren't just infrastructure components that live on a server any more. They're delivered via an API and could be almost anything underneath as the abstractions start to pile up.

    COBOL code at the other end of a message bus with a lambda-function frontend? Okay. Ephemeral container running a Spring Boot service that connects to an RDBMS on a physical Unix server on the other side of the country? Sure, why not? Modern applications don't really care, because it's all about getting the job done. The name of the game is loosely-coupled modular components.

    This is why Docker has joined forces with Microsoft, Bitnami, HashiCorp, and a few others to create the Cloud Native Application Bundle (CNAB) specification. Docker uses this spec as part of its Docker App tool, which behaves a lot like docker-compose to collect a variety of services together into a single application bundle that can be shared around. It's a lot like a container collection, and brings the same easy portability of containers to composed applications.

    "[Docker App] allows you to describe not just containers, but other services around which the app is dependent," says Johnston. "And it allows you to do things that enterprises care about, such as signing the bundle, verifying that signature, and automatically promoting it based on that signature and things like that."

  • Red Hat OpenShift Service Mesh is now available: What you should know

    As Kubernetes and Linux-based infrastructure take hold in digitally transforming organizations, modern applications frequently run in a microservices architecture and therefore can have complex route requests from one service to another. With Red Hat OpenShift Service Mesh, we’ve gone beyond routing the requests between services and included tracing and visualization components that make deploying a service mesh more robust. The service mesh layer helps us simplify the connection, observability and ongoing management of every application deployed on Red Hat OpenShift, the industry’s most comprehensive enterprise Kubernetes platform.

    Red Hat OpenShift Service Mesh is available through the OpenShift Service Mesh Operator, and we encourage teams to try this out on Red Hat OpenShift 4 here.

  • Catching up with Red Hat at Sibos 2019

    Red Hat is excited to once again be attending Sibos, an annual financial services industry conference exhibition and networking event that is hosted by SWIFT. This year, the event is being held in London, England from September 23rd through 26th. Red Hat will be attending to sponsor a number of activities and discuss how and why enterprise open source technologies offer innovative capabilities that can help firms thrive in their digital journeys.

When Diverse Network ASICs Meet A Unifying Operating System

And it has also been a decade since switch upstart Arista Networks launched its Extensible Operating System, or EOS, which is derived from Linux. [...] The cross-platform nature of ArcOS, coupled with its ability to run in any function on the network, could turn out to be the key differentiator. A lot of these other NOSes were point solutions that could only be deployed in certain parts of the network, and that just creates animosity with the incumbent vendors that dominate the rest of the networking stack. Given the mission-critical nature of networking in the modern datacenter, it costs a great deal to qualify a new network operating system, and it can take a lot of time. If ArcOS can run across more platforms, qualify faster, and do more jobs in the network, then, says Garg, it has a good chance of shaking up switching and routing. “That totally changes the business conversation and the TCO advantages that we can bring to a customer across the entirety of their network.” Read more

  • 9 steps to awesome with Kubernetes/OpenShift presented by Burr Sutter

    Burr Sutter gave a terrific talk in India in July, where he laid out the terms, systems and processes needed to setup Kubernetes for developers. This is an introductory presentation, which may be useful for your larger community of Kubernetes users once you’ve already setup User Provisioned Infrastructure (UPI) in Red Hat OpenShift for them, though it does go into the deeper details of actually running the a cluster. To follow along, Burr created an accompanying GitHub repository, so you too can learn how to setup an awesome Kubernetes cluster in just 9 steps.

  • Weaveworks Named a Top Kubernetes Contributor

    But anyone who knows the history of Weaveworks might not be too surprised by this. Weaveworks has been a major champion of Kubernetes since the very beginning. It might not be too much of a coincidence that Weaveworks was incorporated only a few weeks after Kubernetes was open sourced, five years ago. In addition to this, the very first elected chair of the CNCF’s Technical Oversight Committee, responsible for technical leadership to the Cloud Native Foundation was also headed up by our CEO, Alexis Richardson(@monadic) (soon to be replaced by the awesome Liz Rice (@lizrice) of Aqua Security).

  • Improving trust in the cloud with OpenStack and AMD SEV

    This post contains an exciting announcement, but first I need to provide some context! Ever heard that joke “the cloud is just someone else’s computer”? Of course it’s a gross over-simplification, but there’s more than a grain of truth in it. And that raises the question: if your applications are running in someone else’s data-centre, how can you trust that they’re not being snooped upon, or worse, invasively tampered with?

  • Red Hat OpenStack Platform 15 Enhances Infrastructure Security and Cloud-Native Integration Across the Open Hybrid Cloud

    Red Hat, Inc., the world's leading provider of open source solutions, today announced the general availability of Red Hat OpenStack Platform 15, the latest version of its highly scalable and agile cloud Infrastructure-as-a-Service (IaaS) solution. Based on the OpenStack community’s "Stein" release, Red Hat OpenStack Platform 15 adds performance and cloud security enhancements and expands the platform’s ecosystem of supported hardware, helping IT organizations to more quickly and more securely support demanding production workloads. Given the role of Linux as the foundation for hybrid cloud, customers can also benefit from a more secure, flexible and intelligent Linux operating system underpinning their private cloud deployments with Red Hat Enterprise Linux 8.

  • Red Hat Ansible Automation Accelerates Past Major Adoption Milestone, Now Manages More Than Four Million Customer Systems Worldwide

    Red Hat, Inc., the world's leading provider of open source solutions, today announced that more than four million customer systems worldwide are now automated by Red Hat Ansible Automation. Customers, including Energy Market Company, Microsoft, Reserve Bank of New Zealand and Surescripts all use Red Hat Ansible Automation to automate and orchestrate their IT operations, helping to expand automation across IT stacks.
