Cloud infrastructure monitoring and reliability review

The problem

What usually goes wrong

Environments often grow one resource at a time. After a while it is unclear which alerts matter, whether backups can actually be restored, and what happens when a single component fails.

Approach

How we approach it

1. 1

   Inventory resources, dependencies, and data flows, and produce an up-to-date architecture diagram.

2. 2

   Review metrics, logs, and alert rules against the failure modes that would actually hurt the business.

3. 3

   Check backup configuration and test that a restore produces a usable system.

4. 4

   Review network exposure, private endpoints, DNS, and TLS configuration.

5. 5

   Deliver a prioritised list of findings with effort estimates, starting with the highest-risk items.
