This post was partially written by and edited using ChatGPT. Last month the Resolver development team had their first official hack week, which was dedicated to checking out the potential to improve our software with the help of OpenAI. What is OpenAI?

Talking robots! Let’s talk about APIs
What is an API? API stands for Application Programming Interface, let’s break that down: Interface – Every device we use has some kind of interface.

VPCs are a way of partitioning infrastructure in AWS to isolate them from communication with other infrastructure. They operate at the network level similar to VLANs and block all external communication by default. However, sometimes it is necessary to allow some inter-VPC communication. For example, if you have multiple AWS accounts that need to access […]
Last time, we looked at building a deployment pipeline using CodePipeline. Given the increasing number of countries that are implementing data residency policies, we now need to be able to deploy a copy of our application in a different region along with its database and connected services at the same time as in the main region […]
