같이 공부해서 합격해보자구요 !
Section 11 : Classic Solutions Architecture Discussions
124. Instantiating applications quickly
- EC2 instances
- use golden ami - install application, os depdencies beforehand and save them as ami
- bootstrap using user data
- hybrid - mixture of golden ami and user data == elastic beanstalk
- rds db
- restore from a snapshot
- ebs volumes
- restore from a snapshot
125. Beanstalk Overview
- typical architecture = web app 3-tier
- public subnet = elb, route 53
- private subnet = auto scalin group, ec2
- data subnet = elasticache, amazon rds etc
- developer problems on asws
- managing infrastructure
- deploying code
- configuring
- scaling concerns
- most web apps have the basic same architecture (alb + asg)
- elastic beanstalk - a developer centric view of deploying an application on aws
- beanstalk is free but will cost money for inner services
- beanstalk components
- application - environments, version, configuration
- application version - an iteration of your code
- environment - can create multiple env, web env and worker environemtn
- web env - basic web app env
- worker env - message queue env
- elastic beanstalk provdies two development modes
- single instance - great for dev
- high availability with load balancer - great for prod
예상 질문들
1. The software takes over an hour to set up on a linux machine, how do you recommend speed up the installation process when thers a scale out event ?
- bootstrap using ec2 user data = although automatic, is wrong because when scaling out, installation is still required
- use a golden ami = correct answer
같이 파이팅해서 합격해봅시당 ㅎㅎ
