AWS Certificate Manager (ACM)
---
- to host public ssl certs in aws, you can
- buy own and upload using cli
- have acm provision and renew public ssl certs for you
- free
- acm loads ssl certs on following integrations
- load balancers
- including ones created by EB
- cloudfront distributions
- apis on api gateways
- manually managing ssl certs is a pain so acm is a great service to leverage
- eg. when certs expire need to reload and transfer security

- users connect to our alb
- alb has ssl termination
- when users using public internet talking via https terminate, the request is transformed into http
- ACM provisions and maintain cert on the alb
- when https req made to alb, alb makes priv aws http request (not https) to ec2
- thanks to ssl termination, only alb deals with https not our ec2 instances
- less cpu costs on ec2 from decrypting/encrypting
- also dont have to manage ssl certs on ec2 instances

### Console
- private CA is out of scope for exam



- can click create record in route 53

- wait awhile for cert to be issued

- can config alb listener with the ssl cert in beanstalk

---
