Question: What is Elastic IP addresses in aws?
An Elastic IP address is a static IPv4 address designed for dynamic cloud computing.
An Elastic IP address is associated with your AWS account.
With an Elastic IP address, you can mask the failure of an instance by rapidly remapping the address to another instance in your account.

Question: What is IPv4?
Internet Protocol Version 4 (IPv4) is the fourth revision of the Internet Protocol and a widely used protocol in data communication over different kinds of networks.

Question: What is difference between IPv4 and IPv6?

Question: What is EC2 instance in aws?
An EC2 instance is a virtual server in Amazon's Elastic Compute Cloud (EC2) for running applications on the Amazon Web Services (AWS) infrastructure.

Question: What is volume in aws?
An Amazon EBS volume is a durable, block-level storage device that you can attach to a single EC2 instance.
You can use EBS volumes as primary storage for data that requires frequent updates, such as the system drive for an instance or storage for a database application.

Question: What is Amazon EC2 Dedicated Hosts?
An Amazon EC2 Dedicated Host is a physical server with EC2 instance capacity fully dedicated to your use.
Dedicated Hosts can help you address compliance requirements and reduce costs by allowing you to use your existing server-bound software licenses.

Question: What is EBS Snapshots?
We back up the data on Amazon EBS volumes to Amazon S3 by taking point-in-time snapshots.
Snapshots are incremental backups, which means that only the blocks on the device that have changed after your most recent snapshot are saved.

Question: What is Elastic Load Balancing?
Elastic Load Balancing distributes incoming application traffic across multiple EC2 instances, in multiple Availability Zones.
The load balancer serves as a single point of contact for clients(like browser), which increases the availability of your application.
You can add and remove instances from your load balancer as your needs change, without disrupting the overall flow of requests to your application

Question: What Is Amazon VPC?
