  • High availability
  • Fault tolerance
  • Integrated with auto-scaling
  • Ease of management
  • SSL/TLS termination

What is the difference between Scalability and Flexibility in AWS?

  • Scalability – It is the ability to efficiently handle increasing workloads by dynamically adjusting computing resources. It provides scalable solutions that allow us to adjust our computing capacity based on the changing requirements of our system. There are mainly two types of scalability in AWS – Vertical Scalability (Scaling Up) and Horizontal Scalability (Scaling Out).
  • Flexibility – It allows users to customize cloud resources, costs, scalability, and services. Also, We can say that flexibility means that users can adopt and customize their computing environment as per their needs.

What are the major components of AWS?

AWS provides a wide range of services and to meet the requirement it has several components which are used as per the requirement. Some of its key components are as follows

  • Amazon EC2 (Elastic Compute Cloud) – It is a virtual server in the cloud. It allows you to run applications by providing scalable computing power.
  • Amazon S3 (Simple Storage Service) – It is a scalable cloud storage that provides a durable and secure way to store and retrieve any amount of data over the Internet. It is commonly used to archive, backup, and host static web content.
  • Amazon VPC (Virtual Private Cloud) – It is a service that helps you create a private, isolated network and launch AWS resources in the AWS cloud.
