Red Hat Virtualization 4.4 brings new features for managing virtual machines
Red Hat today introduced a new version of its virtualization platform, Red Hat Virtualization 4.4, that will help customers more easily manage their applications and give its hybrid cloud strategy a boost in the process.
Red Hat Virtualization is an alternative to VMware Inc.’s vSphere. The platform runs on the IBM Corp. subsidiary’s widely used enterprise Linux distribution, RHEL, and provides features for managing large fleets of virtualized applications.
Red Hat Virtualization 4.4 has been updated with support for the latest release of RHEL that Red Hat launched in April. That release, officially RHEL 8.2, introduced performance improvements as well as monitoring features that make it easier to identify security and reliability issues. Red Hat Virtualization customers can now take advantage of those enhancements by upgrading the operating system installations in their deployments.

Critical API security risks: 10 best practices [Ed: By Security Evangelist and Strategist, Red Hat]
With the meteoric rise of microservices and the rush to build more applications more quickly, APIs are being used more than ever to connect services and transfer data. But with a growing number of smaller application "pieces" trying to communicate with each other, APIs (your own and those from third parties) are becoming increasingly challenging to secure.

Kubernetes is the future: But what does this future look like?
When industry influencers and CIOs talk about the future of computing, they typically aren’t only discussing hardware advancements or cloud-based software. Increasingly, these conversations center on transformation through application innovation, providing new predictive services to customers that are driven by an integrated user experience. This could be something like inspecting customer data patterns to promote new banking services, analyzing health indicators to proactively recommend treatment or an immersive interface for personalized interactions.
Whatever the end product, it’s about gaining a competitive advantage in an ever-evolving, highly-competitive marketplace through technological advancement. Enter containers. Containers enable these applications to evolve faster, increase developer velocity and bring a greater level of portability and consistency regardless of underlying infrastructure.
Gartner predicts that, by 2022, more than 75% of global organizations will be running containerized applications in production, which is a significant increase from fewer than 30% in 2019.1

Fedora 33 To Offer Stratis 2.1 For Per-Pool Encryption
While Fedora 33 is slated to default to the Btrfs file-system for desktop spins, for those on Fedora Server 33 or otherwise not using the defaults will have Stratis Storage 2.1 as another option.
Red Hat's Stratis Storage has been their effort to improve the Linux storage stack while building upon LVM, Device Mapper, and XFS for offering ZFS/Btrfs-like features. Stratis continues making great progress and is ultimately committed to by Red Hat as part of their Linux storage play, potentially with it being used by default come Red Hat Enterprise Linux 9. Meanwhile the Fedora community has been dabbling with Btrfs on the desktop side for Fedora 33 and thankfully both technologies continue to be fostered by Fedora.

Document APIs with open source OpenAPI Comment Parser
Whether you’re building an application or website, great documentation is crucial to the success of your service. Developers need instructions on how to use your API and they need a way to try it out. Good documentation handles both.
The OpenAPI Specification is an open standard for defining and documenting your API. The OpenAPI Specification enables the generation of great documentation, but creating an OpenAPI spec takes a lot of time and effort to create and keep up-to-date. Often, the OpenAPI spec ends up a large, forgotten, thousandl-ine file.
To help make it as easy as possible to document an API, today we are launching the OpenAPI Comment Parser. The goal of OpenAPI Comment Parser is to give developers a way to generate this OpenAPI spec from comments inline with their code. When the OpenAPI spec lives inside the code, developers are much more likely to keep it up-to-date as their code changes.
