An interesting usecase I have encountered recently is establishing a secure path (bridge) between Traefik as ingress controller and its destination backends.

The post addresses traefik usage within Kubernetes, however it is applicable to other offerings.

When you have working knowledge in the cloud and AWS specifically, it is optimal to seek first the associate level certificates since they’re information oriented with good study and practice, your chances for passing are high. By doing so, you also prepare for the professional and specialty levels afterward.

I have enjoyed reading this piece on stability and reliability by Colm MacCárthaigh. It is part of a concise and valuable series by AWS authors on the art of system operations collected under the name “Amazon Builders’ Library”.

Reuse and module sharing in Ansible can be achieved through two methods: A “Role” which forms conceptually a single component and its related tasks.

Helmfile is an orchestrator tool for collecting, building, and deploying cloud-native apps. Basically it’s the packager for helm chart based applications.

One of the interesting ideas I came along recently, is utilizing it for working in air-gapped environments, where access to the internet is not feasible.
