What is it?
AWS Systems Manager is one of the 'bigger' AWS services: it covers a whole load of things, from analysing incidents, system data analytics and a ton of other stuff.
Why did we choose it?
Specifically for the Parameter Store part of it, for secure parameter storage.
What do we use it for?
Storing various credentials that Deserted Chateau's webservers need access to, such as the credentials to access Lambda, S3 and so on. Storing them in Parameter Store means we don't have to keep them on the servers themselves, which would be less secure.
