Complete code: cross-region RDS recovery

28 December 2017 · Paulina Budzoń

After posting the previous post on this topic (Copying RDS snapshot to another region for cross-region recovery) , I noticed a lot of people being interested in using the code I provided as an example. Many were not sure how to make use of it, and after a couple of pull requests it became obvious that a complete, fully-working code and CloudFormation template would be a good idea. So, yesterday, I pushed an update to aws-maintenance repository with a fully working code, which you can easily customize via CloudFormation parameters to match your needs.

How I passed Red Hat Certificate of Expertise in Ansible Automation exam (EX407)

I have recently passed Red Hat’s EX407 (Red Hat Certificate of Expertise in Ansible Automation exam) and I wanted to share my experience for anyone else who might be looking into getting that certificate. At the time of my exam, I was only a second (publicly visible) person in the UK who had that certificate. Probably because it was only made available in summer this year.

Deployment pipeline, part 3: deployment onto an environment

7 October 2016 · Paulina Budzoń

The purpose of every deployment pipeline is… a deployment. So this final part of the series, will focus on just that. If you missed the intro, check out the video where I describe a typical pipeline here. The other parts of this series are part 1: test phase and part 2: build phase.

Once we create an AMI that we’d like to deploy, performing a rolling update on existing instances is fairly easy. Usage of Auto scaling groups and CloudFormation makes it even easier - since AWS Auto scaling groups support the rolling updates out of the box.

Or, if your applications requires blue-green deployments, using CloudFormation is almost essential.
