🔰 Create High Availability Architecture with AWS CLI Using CloudFront , S3 and EBS 🔰

💥 EBS:-

Amazon Elastic Block Store (EBS) is an easy to use, high performance block storage service designed for use with Amazon Elastic Compute Cloud (EC2) for both throughput and transaction intensive workloads at any scale. 

💥S3:-

Amazon Simple Storage Service (Amazon S3) is an object storage service that offers industry-leading scalability, data availability, security, and performance. This means customers of all sizes and industries can use it to store and protect any amount of data for a range of use cases, such as data lakes, websites, mobile applications, backup and restore, archive, enterprise applications, IoT devices, and big data analytics. Amazon S3 provides easy-to-use management features so you can organize your data and configure finely-tuned access controls to meet your specific business, organizational, and compliance requirements. Amazon S3 is designed for 99.999999999% (11 9's) of durability, and stores data for millions of applications for companies all around the world.

💥CloudFront:-

Amazon CloudFront is a web service that speeds up distribution of your static and dynamic web content, such as . html, . css, . js, and image files, to your users. CloudFront delivers your content through a worldwide network of data centers called edge locations.

💥Task Description📄

🔅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.

🖥️Create a key

aws ec2 create-key-pair --key-name "key_name"

✍️Step 1 : Launch an EC2 Instance from CLI

aws ec2 run-instances --image-id    "image_id" --instance-type    t2.micro --count 1 --subnet-id subnet-94565ffc --security-group-ids "Security_group_id" --key-name "key_name"

✍️Step 2 : Now we have to create EBS volume

aws ec2 create-volume --volume-type gp2 --size 4 --availability-zone ap-south-1a

 ✍️Step 3 : Attach EBS Volume to EC2 Instance

aws ec2 attach-volume  --instance-id  "instance-id" --volume-id "volume-id"  --device /dev/xvdf

✍️Step 4 : Now we have to configure webserver for this we have to install httpd

ssh "instance_ip -i "key_name" -l ec2-user sudo yum install httpd -y

🖥️Creating partition :

ssh "instance_ip" -i "key_name" -l ec2-user sudo fdisk /dev/xvdf

🖥️Formatting partition :

ssh "instance_ip" -i "key_name" -l ec2-user sudo mkfs.ext4 /dev/xvdf1

🖥️mounting to /var/www/html

ssh "instance_ip" -i "key_name" -l ec2-user sudo mount  /dev/xvdf1  /var/www/html

🖥️Check partition :

✍️Step 5 : Now we have to create S3 Bucket from CLI

aws s3api create-bucket --bucket "bucket_name" --region "region_name --create-bucket-configuration LocationConstraint=ap-south-1

🖥️upload the image in S3 Bucket

aws s3 cp "file name" s3://"bucket_name"/ --acl public-read-write

✍️Step 6 : Create CloudFront Distribution :

aws cloudfront create-distribution --origin-domain-name "origin_domain_name"

✍️Step 7 : Finally now we create html file in EC2 instance and give the image url of CloudFront
