Canonical's recipe for High Performance Computing

In essence, High Performance Computing (HPC) is quite simple. Speed and scale. In practice, the concept is quite complex and hard to achieve. It is not dissimilar to what happens when you go from a regular car to a supercar or a hypercar – the challenges and problems you encounter at 100 km/h are vastly different from those at 300 km/h. A whole new set of constraints emerges.

How to build DevOps automations with Kosli Actions

Kosli allows regulated organizations to scale their continuous delivery so that they can deploy changes to production at maximum speed without the risk of non-compliance. It does this by recording all of the data you need to get through regulatory events like audits. With Kosli you can record everything that happens in your software delivery process from initial requirement all the way through to deployment to production. Events like builds, tests, scans, code reviews, etc.

The need for speed: achieving high data rates from data centre to cloud

Having decided to embrace the opportunities of the cloud, be it a full migration, or developing a hybrid infrastructure, one of the first questions a business faces is how to transfer all its data into the cloud. This question will evolve rapidly, as the business realises that not only must it continually transfer new data to the cloud, but that the amount of data is going to grow massively.

10 Top Kubernetes Alternatives (And Should You Switch?)

Containers and microservices are revolutionizing how distributed applications are built, run, and optimized. They enable apps to be highly scalable. You can also isolate some areas for updates and patches without shutting down the entire application or service. Yet, managing containers and microservices at scale can be tricky. That’s where a container management platform like Kubernetes comes in – or, as you’ll see below, where the top Kubernetes alternatives shine.

How Squadcast Helps With Flapping Alerts

Often we receive a series of alerts that get auto-resolved within a short period of time. Such alerts are called flapping or transient alerts. In this blog, we'll explore Auto Pause transient alert (APTA) feature that detects flapping alerts and temporarily pause incident notifications hence reducing alert fatigue.

Step-by-step Guide for Monitoring Redis Using Telegraf and MetricFire

Monitoring Redis instances is essential for maintaining performance, reliability, and security. It allows you to detect issues early, optimize resources, and provide a seamless experience for both developers and end-users. Monitoring your database allows you to track key performance metrics such as memory usage, CPU usage, and query response times. By analyzing these metrics, you can identify performance bottlenecks, optimize queries, and ensure that Redis is operating efficiently.

Cortex Notifications: Stay up to date while staying in flow

Notifications are designed to be annoying. Think of your phone buzzing in a quiet room: it demands your attention, lighting up your screen and making noise so you look at it. A notification is supposed to pull you away from whatever you’re working on. They can be useful, but they can also be a nuisance.

SysAdmin's guide to migrating from CentOS

CentOS EOL - Are you affected? CentOS used to be community driven. Imagine an OS being tested by a global community of volunteers against a testing team in a company—that gave CentOS unmatched stability. An OS that came with Securuty-Enhanced Linux (SELinux) by default and also included 10-year support meant it was the favorite of both individual developers and enterprises as well (even Facebook, now known as Meta, used CentOS for its data centers).
