AWS re:Invent 2023, the biggest event in the annual Amazon Web Services (AWS) calendar, is just around the corner. If you’ll be attending in person, it can be difficult to know which sessions will be valuable. In this blog post I’ve listed the sessions that I’m planning on attending as well as a few tips to get the best from the event.

2022-12-30 6 min read Walkthroughs Adam Divall
At AWS re:Invent this year Account Factory Customisations was released. This post will walk you through how to configure and use the new functionality as in my opinion the documentation isn’t particularly clear as to how things work and there were also issues with the implementation steps when I first implemented it. Use Case For my specific situation that I’m utilising this for I want to deploy a VPC that leverages the Amazon VPC IP Address Manager (IPAM) for obtaining an IP CIDR Range since I don’t want to have to manually enter one each time and run the risk of overlapping address space.
