Automate EKS Node Rotation for AMI Releases

In the daily life of a Site Reliability Engineer, the main goal is to reduce all the work we call toil. But what is toil? Toil is the kind of work tied to running a production service that tends to be manual, repetitive, automatable, tactical, devoid of enduring value, and scales linearly as a service grows. This blog post describes our journey to automate our nodes rotation process when we have a new AMI release and the open source tools we built on this.

AppOps - Defining a new category

Virtualization and cloud have forced the need for automation. In the “old” days, it would take weeks for a new physical server to arrive. There was little pressure to install and configure the operating system on it rapidly. We would insert a disc into the drive and then follow our checklist. A few days later, it would be ready to use. But the ability to spin up new virtual machines (VMs) in minutes required us to get better at automating this process.

Hyperconverged Infrastructure and Harvester

Virtual machines (VMs) have transformed infrastructure deployment and management. VMs are so ubiquitous that I can’t think of a single instance where I deployed production code to a bare metal server in my many years as a professional software engineer. VMs provide secure, isolated environments hosting your choice of operating system while sharing the resources of the underlying server. This allows resources to be allocated more efficiently, reducing the cost of over-provisioned hardware.

How to Maximize the Performance of Your Kubernetes Deployment

With Kubernetes emerging as a strong choice for container orchestration for many organizations, monitoring in Kubernetes environments is essential to application performance. Poor application/infrastructure performance impact in the era of cloud computing, as-a-service delivery models is more significant than ever. How many of us today have more than two rideshare apps or more than three food delivery apps?

Kubernetes 1.22 - What's new?

This release brings 56 enhancements, an increase from 50 in Kubernetes 1.21 and 43 in Kubernetes 1.20. Of those 56 enhancements, 13 are graduating to Stable, a whopping 24 are existing features that keep improving, and 16 are completely new. It’s great to see so many new features focusing on security, like the replacement for the Pod Security Policies, a rootless mode, and enabling Seccomp by default. Also, watch out for all the deprecations and removals in this version!
