What is the software part of EC2 instance ?
AMI is the software part’it includes OS , Software Configuration , Application Server & Applications
What is the hardware part of EC2 instance
Instance type ,is the hardware part of EC2 instance
What are the storage types EC2 instance
We have multiple options of Storage for EC2 instance , one of them is gp2General Purpose Root Volume
What is t2.micro ?
Instance type f EC2

In aws Which service track metrices
Cloud Watch
What Firewall are in AWS ?
We have Security Group in aws , which are Virtual Firewall
Explain AMI
What operating system and what software do you want on the instance
What are the different instance sizes
- t2.nano*
t2.micro*
t2.small*
t2.medium
What do you mean by instance type ?
instance type is an template of cpu + ram.like t3.micro gives one vcpu &1 gb of ram
Autoscaling
Increasing & Reducing the instances based on the load.
Availability
High AvailbilitySometimes in autoscaling some instances are crashed , we want to be able to detect and replace it with an healthy instance , to ensure proper availability of application.
How do you simplify creation and management of multiple VMs?
We have to use Auto Scaling Groups .Allow you to create and manage a group of EC2 instances
How do you distribute traffic across multipleEC2 instances?
ELB - Elastic Load Balancing
How do you distribute traff ic across multipleEC2 instances?
ELB - Elastic Load Balancing
What is the minimum and maximum instances are in auto scaling group
Minimum instances in group is one & maximum is 10
What is the easiest way to set up easy to instances with auto scaling groups and elastic load balancing
You may use Elastic Beanstalk
I want to onl deploy an python app on cloud , which service I have to provision .
We have to use AWS Elastic Beanstalk , offering as PaaS
What can be done by Elastic Beanstalk ?
- We can deploy our app2. Create multiple EC2 instances using auto scaling group3. And Loadbalance them using Elastic Load Balance
How to focused Search in AWS Dashboard
use forward slash /EC2 Instances
What is AWS CDK

What is Kubernetes
Open Source Container orchestration
What is Docker and Kubernetes
