EC2 STORE OVERVIEW- Difference B/W AWS EBS And Instance Store

Introduction to EC2 Storage-

Amazon EC2 provides you with flexible, cost-effective, and easy-to-use data storage options for your instances. EC2 basically provides two types of block-level storage. Instances can either be launched with Elastic block storage volume (EBS volume) or Instance store-backed volumes as to their root volumes. Each option has a unique combination of performance and durability. But Aws recommends using EBS storage-backed AMIS as they get launched faster and provide persistent storage.

Most of the IT companies are working or are migrating their infrastructure to the cloud environment for cost reduction, high availability, data security, and hassle-free setup. Companies create or use applications/databases on the cloud, where they need to authenticate via secrets (or credentials). These days protection of passwords is one of the challenges, and hard-coding the secrets into the system would be a major security issue. Hence, we can make use of the AWS service named Secret Manager that will be responsible for the management of secrets.

What is a Secret?

A secret is not just a pair of usernames and passwords. It might contain a set of credentials holding key-value pairs or connection details to access the related services. In AWS Secret manager, a secret has metadata:

An Amazon Resource Name, name of the secret, a description, a resource policy, and tags, ARN for an encryption key (an AWS KMS key that Secrets Manager uses to encrypt and decrypt the secret value), Information of rotation of secret.

AWS LAMBDA – Here’s Everything You Need to Know!

What is Serverless?

To understand what AWS Lambda is, we have to first understand all about serverless architecture. The serverless architecture is a way to build and run applications and services without having to manage infrastructure. Your application still runs on servers. When you run a serverless application, you get the benefit of not worrying about OS setup, patching, or scaling of servers that you would have to consider when you run your application on a physical server.

Serverless applications or platforms have four characteristics:

  • No server management
  • Flexible scaling
  • No idle capacity
  • High availability
