Generating cloudwatch alarms using 'metric math' via CloudFormation and Terraform.

I spend a lot of time working as a consultant with GlobalLogic UK&I with different client teams to deploy AWS infrastructure, and not surprisingly, I see differing levels of maturity and experience within these teams.

While we work with teams with a lot of knowledge, often they concentrate on deploying the applications and infrastructure, but they won’t think about how they can understand how well an application is working. This is an important aspect of working within the Cloud, usually termed monitoring or observability.
