Users of Red Hat Satellite will see changes coming out with regard to how Satellite interacts with Puppet. Satellite has long bundled Puppet in the distribution, using Puppet both as the Satellite installer and for configuration management. Users also had the option to leverage Satellite as an External Node Classifier (ENC) for their Puppet estates. Red Hat acquired Ansible, an imperative configuration management tool, in late 2015.

In the first part of this series, we explored the fastest way to get started with Mattermost Apps. In the second installment, we looked under the hood of a Mattermost App and examined how it works and how its components interact with each other. In this piece, we’ll outline the various authentication methods available using the Mattermost Apps framework.

The high demand to deliver software that is both highly available and able to meet customer requests has, in part, led to the adoption of microservice architecture, a software architecture pattern that makes it easier to deploy applications as self-contained entities called containers. These containers are nothing but processes that run as long as the application in them is running.

Fairwinds Insights is Kubernetes governance and security software that enables DevOps teams to monitor and prevent configuration problems in their infrastructure and applications. Not only does Fairwinds simplify Kubernetes complexity, but it also reduces risk by surfacing security and reliability issues in your Kubernetes clusters.

Being a system administrator has become a much sought-after role over the past decade, predominantly because every business relies on its IT infrastructure to run seamlessly and glitch-free. The world needs system administrators now more than ever, which is why there are a lot of opportunities going around with great earning potential.

Every year, the PHP foundation releases a new version of PHP that includes updated features for users. These new releases offer a sweet way to kick off every holiday season for developers and application makers (like me). Just days after its official release, we made PHP 8.1 available for all projects on our Grid plans. Now, you can take advantage of the long-awaited PHP 8.1 features on Upsun.

In our recent webinar, Log4j Log4Shell Vulnerability Explained: All You Need To Know, our Senior Director Security Research expert Shachar Menashe shared information on the security issue and how to detect and remediate it. We are happy to share additional information in the following Q&A, based on the questions raised during the webinar.

We've found a pattern to mock external client libraries while keeping code simple, reducing the number of injection spots and ensuring all the code down a callstack uses the same mock client. Establishing patterns like these is what makes test suites great, and improves developer productivity when writing tests. Here's how it works.

Cloud platforms are not new — they have been around for a few years. And containers have been around even longer. Together, they have changed the way we think about software. Since the creation of these technologies, we have focused on platforms and apps. And who could blame anyone? Containers and Kubernetes let us do things that were unheard of only a few years ago.

This post originally appeared on The New Stack and is re-published here with permission. In our technology-driven business climate, most companies have at least some, if not all, workloads on the cloud. And unlike on-premises networks, these cloud environments lack secure outer perimeters and specific off times. Cloud networks are always on and always available. While convenient, this also means hackers can access them at any time.
