Architecture deliverables
What a cloud engagement can produce
The goal is not only an AWS diagram. The useful output is a system that can be deployed, monitored, secured, restored, and explained.
Cloud readiness review
Map current infrastructure, DNS, SSL, access, backup, deployment, and monitoring gaps before changing systems.
AWS deployment blueprint
Create a practical architecture path with network, compute, storage, security, and operations notes.
Migration and cutover support
Plan lower-risk movement of websites, apps, storage, DNS, and supporting services into AWS or hybrid cloud.
Operations handover
Leave runbooks for deployment, rollback, alerts, backup status, restore steps, and common incident checks.
