The goal of Mattermost Playbooks is to help teams consistently orchestrate any and all recurring workflows. A Playbook is a prescribed, repeatable process that a team has agreed on and formalized as a collaborative checklist saved on their Mattermost server. We at Mattermost use Playbooks for incident collaboration, customer onboarding, and product releases, along with many other complex processes.

One of the most important phrases of DevOps practices is “Test early, test often.” It’s crucial to perform functional testing early with unit tests and integration tests. But it’s equally important to perform non-functional testing. That means you should have performance tests. As markets become more saturated with each passing day, you no longer have the luxury to postpone performance testing until all features are developed.

Dell EMC Isilon is a petabyte-scale network attached storage (NAS) system that allows you to archive unstructured data. Isilon operates in a cluster to provide high availability, and you can scale up its throughput, IOPS, and storage space by adding nodes to your cluster. Isilon automatically replicates your data throughout the cluster to ensure durability and provides caching to minimize data retrieval latency.

More than anything else, Kubernetes troubleshooting relies on the ability to quickly contextualize the problem with what’s happening in the rest of the cluster. As complicated as this may sound, SPEED is really the name of the game. After all, more often than not, you will be conducting your investigation under the glow of fires burning bright in production. Getting relevant context quickly and seeing things holistically is exactly what Komodor was created for.

So you finally are ready to try out some of Azure’s most common and loved technologies.Well the cheap storage they provide is definitely one of them that we do. Whether you want to store your own personal files and photos, or you have a requirement from your business to quickly expand some storage, with Azure its quick and easy to setup, access and use. In this quick tutorial I will run you through just how easy it is to setup an Azure Storage Account.

Many development teams start their CI/CD journey with a local build box (or six) that run their tests. In several mobile teams I worked on, for example, we had a few Mac Mini boxes with physical devices plugged in that we used for running local UI and unit tests. Eventually we migrated to a cloud-based solution, which brought us much greater stability and many new features. But moving to the cloud also meant our local hardware was obsolete.

The lockc project provides mandatory access controls (MAC) for container workloads. Its goal is to improve the current state of container/host isolation. The lockc team believes that container engines and runtimes do not provide enough isolation from the host, which I describe later in the “Why do we need it?” Section. In this blog post, I’ll provide an introduction to lockc, discuss why you need it and show you how to try it out for yourself.

For most SaaS companies, COGS (which stands for cost of goods sold) is used to calculate gross margin and profit. COGS is an accepted term with a specific definition under U.S. Generally Accepted Accounting Principles (GAAP) — and is widely used as part of calculations to gauge the health and valuation of a company. Like many accounting practices, COGS stems from the industrial era, when most businesses were concerned with the creation of physical goods.

As a software engineer, leveraging GitHub is one of those tools that transcend your personal and professional development activities. Bringing open source to the masses, GitHub is a familiar platform for many. A newer addition to the GitHub Platform is GitHub Actions which was originally a workflow engine, now expanding into CI/CD.

The CIS benchmark has hundreds of configuration recommendations, so hardening and auditing a Linux system manually can be very tedious. Every administrator of systems that need to comply with that benchmark would wish that this process is easily usable and automatable. Why is that? Manual configuration of such a large number of rules leads to mistakes – mistakes that cause not only functional problems, but may also cause security breaches.
