Most of the time people think of DNS as a way for internet users to find your website. However, it is also useful for your applications and services to find each other. Let’s say that within your system you have a separate server that provides an AI LLM service via an API. To invoke the […]
Amazon Web Services makes it simple and convenient to provision computer servers in the cloud. However, this ease can quickly lead to expensive monthly bills. AWS Savings Plans offer a discount in exchange for a fixed-term commitment to spend. In this article, I explain that today is the day to purchase a savings plan.
Now that we have a process that automatically builds a container image whenever changes are committed to the git repository, we need a way to get those changes out, either into a development or test environment, or to the production environment. In the gitops world, a deployment is also initiated by a change to the […]
This article is the fourth in the series on how to set up an automated end-to-end workflow for deploying to a Kubernetes cluster. The previous steps accomplished a lot, even if they sound simple. Each involved multiple additional tasks to set up tools and systems, the classic yak shaving scenario. While the first two steps […]
This is the third part of the guide to setting up an automated workflow to deploy code to a Kubernetes cluster following a change in a git repository. The first two parts of this series so far belong in the dev portion of devops. They encompass what most software engineers do to build and test […]
The first article in this series introduced our objective, which is to create an automated workflow that delivers code to a runtime environment once it has been committed to a Git repository. In this part we will look at the next step, which is to package the app so that it can be run in […]

All the service vendors claim to take stringent precautions and implement foolproof processes, but still, vulnerabilities getexploited and errors happen. Therefore, my preference is to use tools […]
