Databases, storage and more.
WHAT THEY ARE
Components the provider operates for you: databases, storage, queues, caches, mail sending.
WHY THEY EXIST
Running these well is specialised work.
WHAT THEY REMOVE
Installation Patching Backup configuration, in many cases Scaling
WHAT THEY COST
More per unit than running it yourself Less in total, once administration time is counted
WHAT THEY CONSTRAIN
Versions and configuration options
WHAT TO CHECK
Whether the managed version supports what you need How backups work and whether you can restore yourself How you would export data
THAT LAST POINT
Establish the exit before adopting.
WHAT TO BE CAREFUL WITH
Provider-specific services with no equivalent elsewhere.
Those are the hardest dependencies to unwind.
WHAT TO PREFER WHERE PRACTICAL
Managed versions of standard technologies rather than proprietary equivalents.
WHY
They can be moved.
