MIGRATING APPLICATIONS TO AWS

Suliman Lei : Cloud Infrastructure Architect @Delaware North

MIGRATION CONSIDERATIONS

Migration Approach & Best Practices Understand Application Stack’s (not Servers)

components that make up the application CPU/Ram /Disk average utilization

Security (public facing vs. private facing)

Know the application owner

Asking the right question! How is the application currently configured ?

Is there current documentation

Networking / Storage / Compute capacity.

IDENTIFY APPLICATIONS TO MOVE

Standalone applications easy to move

Applications with loosely coupled integrations are good candidates.

Tightly integrated applications are hard to move (e.g. Active directory is tightly coupled, may be better to build new and start replication).

INVEST IN PROOF OF CONCEPT EARLY

Proof of concept will answer tons of questions quickly

Will identify gaps and touch points

Give you a good estimation of the task ahead.
