Why Move to AWS — 6 Advantages of Cloud

AWS describes six key advantages of cloud computing:


1. Trade capital expense for variable expense
No upfront hardware costs. Pay only for what you consume.


2. Benefit from massive economies of scale
AWS buys at enormous scale and passes savings to customers.


3. Stop guessing capacity
Scale in minutes instead of weeks. No over-provisioning or under-provisioning.


4. Increase speed and agility
Deploy in minutes; experiment cheaply; fail fast.


5. Stop spending money on data centers
Focus on applications and customers, not infrastructure management.


6. Go global in minutes
Deploy in multiple regions worldwide with just a few clicks.


The 7 Rs of Cloud Migration:

Retire — decommission; no longer needed

Retain — keep on-premises for now

Rehost (Lift & Shift) — move to cloud as-is; fastest

Replatform (Lift & Reshape) — minor optimizations

Repurchase — move to SaaS

Refactor/Re-architect — redesign for cloud-native; most expensive but most benefit

Relocate — move to AWS VMware Cloud
