About

This is a curriculum for learning basic knowledge of AWS services that are frequently used.

In Japanese / 日本語版

README_ja.md is written in Japanese.(The contents are the same.)

Abstraction

Purpose

Purpose of this curriculum is learning AWS basic services for AWS begginers. So, you shouldn't get on next step if you could not master it. Please read AWS official document or ask other skilled person.

How to get on steps

  • Steps are 1 to 9. You should do in order.
  • Please follow these rule about IAM user:
  • When step 1 : You should use IAM user which you already created
  • After step 1: You should use IAM user which you created at step 1
  • Please do at your living region

Services you learn with this curriculum

  • IAM
  • VPC
  • EC2/EBS
  • RDS
  • ELB
  • Route53
  • S3
  • CloudFront
  • CloudWatch

Steps

Step 1: Prepare privilege

1-1: Create IAM policy

  • Create a IAM policy for this curriculum
  • Privilege must be minimum (or simply IAM Full Access)
  • When you have done Step 1, please fix it to Administrator Access

1-2: Create IAM group

  • Create a IAM group for this curriculum
  • Attach IAM policy that you have created to this group

1-3: Create IAM user

  • Create a IAM user for this curriculum using password
  • with Access key, Secret key
  • Attach this user to IAM group that you have created

1-4: Configure MFA

  • Study about MFA
  • Configure MFA to IAM user you have created with Google Authenticator(or Authy)

1-5: Check privilege

  • Install AWS CLI into your local environment with pip
  • Check privilege with following command:
  • aws s3 ls -> Must not do (it will show permission denied)
  • aws iam list-groups -> Must do (it will show iam groups)

Step 2: Prepare network

2-1: Create VPC

  • Study about valid range of IP address for AWS VPC
  • Create VPC with any CIDR

2-2: Create subnet

  • Create 2 subnets into VPC (one is SubnetA, the other is SubnetB)
  • SubnetA and SubnetB must be placed different AZ from each other
  • Each subnet must have only 128 IP addresses

2-3: Create public subnet

  • Study about what Public subnet means in AWS
  • Make SubnetA Public subnet

2-4: Create private subnet

2-4-1: Create NAT gateway

  • Study what NAT is
  • Study what NAT Gateway is
  • Create NAT Gateway into Subnet A

2-4-2: Create private subnet

  • Study what Private subnet means in AWS
  • Make SubnetB Private subnet with NAT gateway

2-5: IP Address of Subnet

  • 5 IP Address per subnet cannot be used. Study why.

2-6: Create security group

  • Create security group into VPC
  • Inbound traffic must be authorized from only your local IP address
  • Outbound traffic must be globally opened

Step 3: Create virtual server

3-1: Create EC2

  • Study about diferrence between EC2 instance types
  • Study what AZ is
  • Create EC2 at SubnetA like this:
  • OS: Ubuntu LTS
  • Storage: 50GB
  • Instance type: t2.small
  • Use tag to name instance
  • Attach security group you have created at step 2-6
  • Use userdata to install nginx (any version is ok)
  • Create key pair

3-2: Login EC2

3-2-1: Check server spec

  • Log in EC2 by SSH
  • Do nginx -v to make sure nginx is installed
  • Do df -h to make sure storage is 50GB
  • Do cat /etc/lsb-release to make sure linux distribution is Ubuntu

3-2-2: Use nginx

  • Create index.html like below and deliver it to internet with nginx

index.html

Hello World! by EC2a
  • Access and see above index.html with your web browser

Step 4: Create database

4-1: Create RDS

  • Study what Multi-AZ is
  • Study what failover is
  • Create RDS at SubnetB like this:
  • Security group: Create new security group and allow traffic only from EC2 you have created
  • MySQL5.6
  • instance type: db.t2.medium
  • Multi-AZ: No
  • master user: root
  • master user password: LzXyDQbYYfTn
  • public access: No
  • name of database: curriculum_db
  • encryption: disables

4-2: Use RDS

  • Login RDS from EC2
  • Create new database user

Step 5: Loadbalancing

5-1: Create EC2

  • Prepare AMI from EC2 already created, and create new EC2 from that AMI (We call this EC2 EC2B, and already created one is EC2A)
  • Create index.html like below and deliver it to internet with nginx of EC2B

index.html

Hello World! by EC2B
  • Access and see above index.html with your web browser

5-2: Create ALB

  • Study about loadbalancing servers
  • Study what ELB is
  • Study about difference from CLB, ALB, NLB
  • Create ALB like this:
  • Scheme: Internet facing
  • IP address type: IPv4
  • Listener: HTTP
  • Target group: EC2A, EC2B
  • Security group: Create new security group and allow traffic only from My-IP

5-3: Use ALB

  • If loadbalancing is configured correctly, both
Hello World! by EC2a

and

Hello World! by EC2b

will be delivered. Make sure this with your browser.

5-4: Enable HTTPS

  • Make this ALB HTTPS-Accessable

Step 6: Use S3

6-1: Upload contents

  • Study why S3 is called Eleven-nine
  • Study about difference from Bucket policy and ACL
  • Study about Eventual Consistency of S3
  • Create curriculum bucket
  • Upload this index.html to curriculum bucket

index.html

Hello World! by S3

6-2: Static Web hosting

  • Enable static web hosting with curriculum bucket
  • Access S3 endpoint from browser and make sure that you can see index.html
  • Study about advantages of static web hosting

Step 7: Use CDN

7-1: Create distribution

  • Study about advantages and mechanism of CDN
  • Create CloudFront distribution like this:
  • Origin: S3 bucket already created
  • Origin path: index.html
  • Restrict Bucket Access: No
  • Cache: 1 hour
  • Don't enable HTTPS

7-2: Use distribution

  • Access distribution and make sure that you can see index.html

Step 8: Use original domain

8-1: Create domain for ELB

  • Study about Route53
  • Study about DNS record
  • Study about ALIAS record
  • Study about TTL
  • Get any domain and set ALIAS record to ELB
  • Study about sinking of DNS
  • Access domain and make sure that you can get response from ELB

8-2: Create domain for CloudFront

  • Get another domain (subdomain is ok) and set ALIAS record to CloudFront distribution
  • Access domain and make sure that you can get response from CloudFront

Step 9: Check metrics

9-1: EC2

  • Check below metrics about EC2 already created from CloudWatch (And, study what they mean)
  • CPUUtilization
  • CPUCreditBalance
  • NetworkIn
  • NetworkOut
  • DiskReadOps
  • DiskWriteOps
  • NetworkPacketsIn
  • NetworkPacketsOut
  • You cannot check memory utilization with CloudWatch. Study how you can check it

9-2: RDS

  • Check below metrics about RDS already created from CloudWatch (And, study what they mean)
  • CPUUtilization
  • FreeableMemory
  • SwapUsage
  • DatabaseConnections
  • BurstBalance

Step 10: Cleaning

  • Check how it costed with resources you have created
  • Clean all resources 😢 ( If you want to do optional lessons, you don't need to do this!! )

Afterword

Well done! You finished all steps of this curriculum. AWS has many services, and it's difficult to understand all of them. But, you know basic knowledge of popular services now.

If you want to do more, do Optional !!

Optional

  • Study about SSL Termination
  • Enable CloudFront distribution HTTPS
  • Study and use spot instance
  • Make RDS Multi-AZ and do force failover
  • Attach EIP to EC2
  • Do weighted round robin with ELB
You can’t perform that action at this time.
