Iv) Storage optimized: When you need to set up a storage server Iii) GPU optimized: For setting up a gaming system, or something with the requirement of a large graphic Ii) Memory-optimized: For setting up something to do with your in-memory cache I) Compute-optimized: For situations that require a lot of processing power Instance types belong to five main families: These AMIs are also available in the AMI MarketplaceĪn instance type specifies the hardware specifications that are required in the machine from the previous step. Ii) Custom AMIs: The user also creates these, and they can be reused. I) Predefined AMIs: Amazon creates these, and the user can modify them. The AMI will contain information about the software, operating system, volume, and access permissions. If at some point in the future, you wanted to create an application using the resources you’ve stored on S3, you’ll need to create an instance EC2.Ģa) Choosing an AMI (Amazon Machine Image):Īn AMI is a template that is used to create a new instance-or virtual machine-based on user requirements. You’ll be able to notify users every time the company creates a newsletter, for example. With Amazon Simple Notification Service (SNS), EC2, and Simple Storage Service (S3), you should be able to do everything you want with ease. How would you let them know about the other services you offer? Imagine if your user base is enjoying your product. Use Case: Notifying Users about a Newsletter Let’s look at EC2(Elastic Cloud Compute) in action. It greatly eases the process of scaling up or down, can be integrated into several other services, and comes with a plan where you only pay for how much you use it. In practice, EC2 makes life easier for developers by providing secure, and resizable compute capacity in the cloud. Among the vast array of services that Amazon offers, EC2 is the core compute component of the technology stack.
