① 用户登录instance
使用AMI 创建 instance
连接 instance: 输入Ipv4 Ip + auth (private key file)
命令：aws s3 ls 用来list bucket(但此时缺少credentials) =>
1. 创建用户 IAM -> add user -> add auth -> download .csv
2. 配置用户凭证credentials：aws configure -> access Key ID + region name
aws s3 ls
aws ec2 describe-instance
aws ec2 stop-instance --instance-ids xxx
② cloudformation - template
-> choose WordPress blog -> 最后输出web url: 创建自己的blog网站
③ Dynamo: 复杂，容量大，session_id
④ EFS
1. 创建EFS, 且EFS和EC2安全组要配置成一样
第二个EC2可以通过“操作” - “配置更多类似项” 快速启动
2. 挂载：EFS - disk mounting to EC2 （using commands）
df -h // check disk usage
EFS acts like a shared disk among instances
⑤ ELB routing polity
ELB healthcheck 检查EC2的负载均衡
DomainName healthcheck 检查域名是否正常
不能用IP，要用domain name（ELB的DNS名称）
simple routing policy 1对1
weighted routing policy 设置50; 150; 10 ...
failover routing policy
- create record set -> EC2 选择primary,S3选择secondary(备用)
模拟EC2 stopped，但DomainName health，因为流量到S3
geolocation routing policy
hosted zones -> create record set -> EC2 -> location Asia -> Asia
create record set -> S3 -> location default -> other region
latency Routing policy
⑥ NAT
NAT gateway: 转private address to public addr
create private instance + public instance(自动分配共有IP)
社区AMI: NAT -> create public NAT -> 创建成功 -> 操作 ->
联网 -> 更改源/目标检查 -> 禁用！（意思是目标addr就是这个instance，但这个是NAT，转发流量）
⑦ S3 Transfer Acceleration
S3 -> choose a bucket -> atrribute -> Transfer Acceleration -> start
⑧ cloudFront - CDN
create cloudFront associated with an S3 bucket
⑨ lambda - auto execute code
set trigger(cron command) + (start/stop instance)code
