Question: Can you explain the difference between EBS and Instance Store volumes?
|
Answer: Amazon EBS (Elastic Block Store) provides persistent block-level storage volumes for use with EC2 instances.
EBS volumes are independent of the EC2 instances they are attached to.
Instance Store volumes, on the other hand, provide temporary block-level storage that is physically attached to the
host computer of an EC2 instance. Instance Store volumes lose their data when the associated instance is stopped or terminated.

|
Answer: A public subnet in a VPC is a subnet with a route to the internet gateway, allowing resources within the
subnet to access the internet.
A private subnet, on the other hand, does not have a route to the internet gateway and is typically used for resources
that should not be directly accessible from the internet, such as database servers or backend systems.

Question: Can you explain the difference between Serverless and Containers in AWS?
|
Answer: Serverless computing (e.g., AWS Lambda) allows you to run code without provisioning or managing servers,
focusing on functions or tasks rather than infrastructure.
Containers (e.g., Amazon ECS, EKS) provide a lightweight, portable, and self-sufficient way to package, deploy,
and run applications, encapsulating everything needed to run the application.
