INTERACTING WITH SERVICES PROVIDED BY AWS

For interaction services provided by AWS we have various ways :

1. Web UI
2. CLI
3. API
4. Cloud Formation

First 3 approaches are Monotonous and harder in terms of Management .

For Example , in CLI we have scripted or Imperative approach where we have to tell

1. What to do
2. How to do

but Approach 4 is Declarative Approach where we only have to tell

1. What to do

AWS has its own tool service called as CLOUD FORMATION that help us with Automation and is declarative.
