Three years passed from the last AWS exam I took, and my AWS certifications were due for renewal.
The first thing I checked was the exam code, which I had taken three years ago.
It turns out that last time I took the SAA-C03, and this time I would also have taken the same exam.
This time around, I considered doing the SAP-C02 instead, but, given the very limited time, I decided on the SAA-C03.

For years, I hosted this blog and several other services on AWS. AWS is powerful, but it is also expensive and deeply entropic. It often feels like every problem on AWS has three different services as possible solutions. Each service has its own setup, and keeping track of everything just gets harder over time. For personal infrastructure, the financial and cognitive cost simply stopped being worth it.
That’s why I decided to close my AWS account and move everything somewhere else.

Although the definitions of Open Source are related to specific software characteristics (i.e., the license), the reality is much more complex. Open-source is way more related to a social contract that the software’s creator and its users morally sign than the definition might lead you to believe. This social contract’s key aspect concerns the software’s current license and the licenses of future versions. This is because although users of open-source software usually do not pay to use it, they incur high costs to do so. Examples of those costs are training costs and potential costs to replace a certain technology should it become unavailable in the future.

I often talk with people about Service Level Agreements (SLAs) in public cloud contexts, and I discover that their idea of what those SLAs are is often distorted.
I believe SLAs need to be approached with a healthy dose of skepticism. In reality, they often provide little meaningful recourse when things go awry. There are two big issues, in my opinion, with the SLA provided by many companies, including the hyperscalers:

Recently, I heard a pitch from a public cloud company. Among other characteristics, a key aspect they stressed is that they are the cheapest cloud. This aspect struck me. Not because I believe it is or is not, but because I’ve heard many companies pitch themselves as the cheapest cloud over the years. I asked the CTO if they were foreseeing consistent and planned cuts in the pricing every year or so. The CTO’s answer was very sensible but negative on the specific point. Later the same day, I was thinking more about my interaction with that CTO, and it became clear to me why pitching to be the cheapest cloud is not a good idea.

This website is hosted on AWS S3 and uses AWS CloudFront as CDN. I use a couple of AWS Lambda@Edge functions to make AWS CloudFront a little brighter. When I decided to self-host a Fediverse instance, it became immediately evident that I would have to set up WebFinger on my domain to be able to use my root domain as the account domain. There is documentation on the web on how to set up WebFinger, but it is aimed at different setups, so I had to configure it myself.

Three years passed from the last AWS exam I took, and my AWS certifications were due a renewal.
The first thing I checked was what was the exam code and which one I had taken three years ago.
It turns out that the last time I took SAA-C01, this time, the only available version for the AWS Solutions Architect Associate exam was SAA-C03.
SAA-C03 is still very new since it got released last month, so not much third-party material is available.

We have seen a massive increase in the “real world” dependency on digital services in the last few years. This process will probably continue in the future, and we are not ready for it. In the same few years, we have seen a lot of cases where digital services went offline or got hacked. In a society that relies more and more on digital services, we can not afford such services not to be available or secure. Although security is essential, I want to focus on availability for now.
