Create High Availability Architecture with AWS CLI

✳️The architecture includes-

⭕ Webserver configured on EC2 Instance

⭕Document Root(/var/www/html) made persistent by mounting on EBS Block Device.

⭕Static objects used in code such as pictures stored in S3

⭕Setting up Content Delivery Network using CloudFront and using the origin domain as S3 bucket.

⭕Finally place the Cloud Front URL on the webapp code for security and low latency.

Step 1:

Create an IAM user to access AWS CLI. Then use the following command to access the AWS service through CLI,

aws configure

Then create a key pair to launch an instance

aws ec2 create-key-pair --key-name <key_name>

Launching an instance.

aws ec2 run-instances --image-id <imageid> --instance-type <instancetype> --key-name <keyname> --security-group-ids <securitygroupid>

Step 2:

Create an EBS volume

aws ec2 create-volume --availability-zone <region_name> --size <size>

Attach an EBS volume to the launched instance,

aws ec2 attach-volume --instance-id <instance id> --volume-id <ebs volumeid> --device <device name>

Step 3:

Install Apache Server On The Instance

yum install httpd

Start the Service,

systemctl start httpd

Step 4:

Create a Partition on the attached EBS volume:

fdisk /dev/xvdf

Format the partition:

mkfs.ext4 /dev/xvdf1

Mount the Partition:

mount /dev/xvdf1 /var/www/html/

lsblk

Step 5:

Create a S3 Bucket,

aws s3api create-bucket --acl public-read-write --bucket <bucket name> --region <region name> --create-bucket-configuration LocationConstraint=<region name>

Upload your picture to the S3 Bucket

aws s3 cp <image name> <url>

Step 6:

Create a Cloud Front Distribution:

aws cloudfront create-distribution --origin-domain-name <s3 domain name>

Step 7:

Go to the path /var/www/html in your instance and create an .html file and add the cloud front URL in your script

Now lets take a look at our Web page

http://<instance ip>/filename.html

webpage is ready with great Security and Low latency
