Create High Availability Architecture with AWS CLI

ARTH - Task 6 👨🏻‍💻

🔅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.

The EC2 instance was configured as the webserver . Webserver used is Apache httpd.

To install httpd on webserver use :

yum install httpd

After mounting EBS block we create a S3 bucket.An Amazon S3 bucket is a public cloud storage resource available in Amazon Web Services' (AWS) Simple Storage Service (S3), an object storage offering. Amazon S3 buckets, which are similar to file folders, store objects, which consist of data and its descriptive metadata.

For creating S3 bucket :

But we get error on this command because of unspecified location constraint. This error happens because regions outside of us-east-1 require the appropriate LocationConstraint to be specified in order to create the bucket in the desired region.

So we run this command:

We can see our bucket created in the AWS WebuI.

Uploading a file to the S3 bucket , we run the following command

Similarly we can see the file uploaded in our bucket on the AWS web ui.

For reducing latency and increasing security for delivery of data , we use CDN provided by Amazon Cloudfront.

A content delivery network, or content distribution network, is a geographically distributed network of proxy servers and their data centers. The goal is to provide high availability and performance by distributing the service spatially relative to end users.

For creating distribution run -

At last we can view various stats , such as cache statistics and cloud front viewers

Updating our code to use CloudFront service:
