History Over the last few years AWS has branched out into building their own ARM based processor named Graviton and also to providing instances powered by other x86_64/AMD64 architectures, namely AMD EPYC processors. In late 2019, they also introduced their second generation Graviton2 processor. Though, this isn’t the first time AWS has used AMD processors. If you have been around AWS for a while you may remember in about 2011/2012, you used to be able to order an m1 instance family. Read more

AWS has provided the ability to implement fine-grained access control using attributes (such as ResourceTags) for serveral years now. Recently I had the need to provide access to certain EC2 instances and was really hoping that I didn’t have to list all EC2 instances for attribute access to work. Unfortunately after a lot of trial and error I couldn’t make it work, and ended up with the following policy, deployed via Control Tower/SSO using a permission set against the specific account where the EC2 instances are running.

Introduction Recently AWS announced support for containers in their Lightsail service. Lightsail is a service that acted like a traditional VPS type service. Very opinionated and limited capability, but with very simple pricing constructs and really simple approach to get up and running. With this announcement you can now add containers to Lightsail and it’s really easy to get going. One issue I did run into, not sure what’s going on is is a continual login to Lightsail 400 error, Request Header or Cookie Too Large. Read more

A little history Earlier this year we finally got NBN at our house. When we moved in about 3 years ago, it was supposed to be commissioned (or RFS, ready for service in NBN parlance) in about 6 months. Then it kept moving out and out and out and out. You get the idea. Needless to say this ended up with finding the Telstra Wholesale RFS list (now defunct) and a friend of mine building a site to track the changes. Read more

I’ve been starting to use CDK over the last few months. It’s a really powerful way to describe your infrastructure. I’m specifically been using Python, so much of what I discuss here will be in Python where I need to reference languages. One of the things that I really liked about it, is that creating MVPs or PoCs can be really quick as there are high level constructs available out of the box. Read more
