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.

Here, I have used 2 RHEL8 systems and configured one system as a MasterNode or NameNode and another system as a DataNode .
Let me describe how you can provide elasticity to DataNode storage , i.e, increase/decrease the storage capacity on the fly by using the concept of Logical Volume Management (LVM)
Add 2 hard disks to the system you have configured as a datanode
Let’s see the routing table using the command:
We see that there is a rule in the routing table for destination 0.0.0.0 which means that your system can reach any other system

The AWS Command Line Interface (CLI) is a unified tool that manages the AWS services for you.
AWS CLI gives you the ability to automate the entire process of controlling and managing AWS services through scripts. These scripts make it easy for users to fully automate cloud infrastructure.
Let’s perform the following using AWS CLI
aws help command, we can create our customized commands
Cloud computing is the on-demand delivery of IT resources over the Internet with pay-as-you-go pricing. Instead of buying, owning, and maintaining physical data centers and servers, you can access technology services, such as computing power, storage, and databases, on an as-needed basis from a cloud provider like Amazon Web Services (AWS).
Organizations of every type, size, and industry are using the cloud for a wide variety of use cases, such as data backup, disaster recovery, email, virtual desktops, software development and testing, big data analytics, and customer-facing web applications.
You can quickly spin up resources as you need them–from infrastructure…
