Production Data Simulation: Record in One Environment, Replay in Another

Have you ever experienced the problem where your code is broken in production, but everything runs correctly in your dev environment? This can be really challenging because you have limited information once something is in production, and you can't easily make changes and try different code. Speedscale production data simulation lets you securely capture the production application traffic, normalize the data, and replay it directly in your dev environment. There are a lot of challenges with trying to replicate the production environment in non-prod.

How to build an EKS kubernetes cluster with Ubuntu 20.04 on FIPS mode

Many clients have specific requirements for running their EKS Kubernetes clusters with Ubuntu: OS alignment across platforms, sysadmin knowledge or specific kernel features such Real Time Kernel or FIPS mode. If your workloads need to run on FIPS mode for compliance, you will not only need to create your containers on FIPS mode (in other words, with FIPS certified crypto libraries) but also, since containers share kernel with host/worker nodes, you need to have also the worker node's kernel running on FIPS mode.

Why is Open Source Important to Enterprise IT Leaders?

A recent global survey demonstrates the importance of open source tools and technologies to IT professionals and their organizations.

The results? Sixty-three percent of those surveyed said it was highly important for their organizations to choose open source tools and technologies.

Kubernetes ErrImagePull and ImagePullBackOff in detail

Pod statuses like ImagePullBackOff or ErrImagePull are common when working with containers. ErrImagePull is an error happening when the image specified for a container can’t be retrieved or pulled. ImagePullBackOff is the waiting grace period while the image pull is fixed. In this article, we will take a look at.
