EC2 to Raspberry Pi WordPress Migration: Full Guide
How I moved andrewbaker.ninja off AWS, saved hundreds of dollars a year, and ended up with better security in the process. Running a personal site on AWS is completely reasonable when you are starting out. The tooling is mature, the reliability is excellent, and you can spin up a new instance in seconds.

Why Multicloud Is Not a Cloud Resilience Strategy
There is a particular kind of nonsense that circulates in enterprise technology conversations, the kind that sounds like wisdom because it wears the clothes of prudence. Multicloud architecture as a cloud resilience strategy is that nonsense. It has the shape of risk management and the substance of a comfort blanket, and the industry has spent […]

Reverse Engineer AWS to Terraform: CloudToRepo Guide
If you have ever inherited an AWS estate, you know the feeling before you can even describe it. Hundreds of resources spread across regions you did not know were enabled.

Andrew Baker, Chief Information Officer at Capitec Bank There is a class of AWS architecture mistake that is genuinely difficult to see.

CloudScale Free WordPress Backup & Restore Plugin Guide
I’ve been running this blog on WordPress for years, and the backup situation has always quietly bothered me. The popular backup plugins either charge a monthly fee, cap you on storage, phone home to an external service, or do all three.

Aurora Serverless v2 PostgreSQL: Production Scaling Guide
Aurora Serverless v2 promises the dream of a database that automatically scales to meet demand, freeing engineering teams from capacity planning. The reality is considerably more nuanced. After running Serverless v2 PostgreSQL clusters under production workloads, I have encountered enough sharp edges to fill a blog post. This is that post. The topics covered here […]

When WordPress goes down on your AWS instance, waiting for manual intervention means downtime and lost revenue. Here are two robust approaches to automatically detect and recover from WordPress failures.
