To unlock innovation potential and implement agile processes, organizations have been migrating workloads to the cloud. Amazon EC2 is a popular service offered by the cloud leader. It is used by developers to plan application migrations to AWS. Amazon Elastic Cloud Compute, or EC2, allows your cloud team to quickly launch virtual servers to run workloads. EC2 changes the economics of how your company purchases IT infrastructure. It transforms from an ownership-based model into a pay-as you-use model. Customers can enjoy many benefits from EC2 and its supporting tools.
This article will provide information about Amazon EC2 and the types of instances that can be launched from EC2, Regions, Availability Zones, and other tools related to EC2. This article will explain how EC2 works, and the AWS training required to use the service to optimize performance and cost.
The free AWS eLearning training is available to developers, solutions architects, and cloud professionals who wish to learn more about Amazon EC2. Professionals can access more than 250 AWS eLearning video courses.
What is Amazon EC2 exactly?
EC2 is an AWS service that allows your cloud team to launch instances or virtual server within minutes. Your cloud team has many options to choose from depending on your workloads. Your team can create security and networking features for the instances, and manage storage by attaching them Elastic Block Store or to other data storage services.
EC2 has the following features:
You can create virtual environments through EC2 that you can use to deploy apps and workloads.

AWS offers several types of instance. They differ in their storage, memory, and CPU. It can help you select the right instance for your workload.

To launch an instance, you can use the Amazon Machine Image (AMI). AMI provides information about the configuration of the instance

AWS offers the key pairs feature that allows you to manage login access to instances

To increase failure tolerance, you can spread the instances over multiple Regions or Availability Zones.

Types of Amazon EC2 Instances
Amazon EC2 instances can be grouped into families based upon their computing capacity, storage, and memory. The type of workload you are planning to run can help your cloud team choose the right instance. Instance families have a lower minimum and a higher maximum for the shared resources within the instance group.
The EC2 instances can be divided into three types based on their characteristics and the types of workloads they can support.
Compute-optimized instances can be used for high-performance applications such as scientific modeling, media transcription, batch processing, high performance servers, dedicated gaming servers, or even machine learning projects.

These instances can be used for large data sets that need to processed quickly. These instances are used in projects that involve relational and NoSQL database, in-memory databases supporting business intelligence, apps for processing real-time unstructured information, and EDA applications.

When large amounts of data are required, storage-optimized instances will be preferred. When large databases are involved, the cloud teams prefer storage optimized instances. Processing should be fast. Storage optimized EC2 instances include MPP data warehouse, Hadoop workloads and data-intensive workloads.

What is Amazon Machine Image?
AMI is a virtual appliance, a template that can be used to launch EC2 instances. An AMI can be used to launch multiple instances. Developers may need to register different AMIs if they have different configurations.
There are many types of AMIs. They can be classified according to the Region, operating systems, architecture, launch permissions and storage for root device. AMIs speed up software development because you can quickly configure multiple instances.

Greater availability with Zones and Regions
Multiple Regions can be used to distribute EC2 instances, increasing fault tolerance and workloads. The EC2 Regions can be isolated from each other. AWS manages the datacenters to minimize the chance of failure. The workloads are not affected by a failure at any of the datacenters.
Each Region is divided into Availability zones. Architects and developers can plan the infrastructure so that if an instance in one Zone fails, requests can be handled by instances from other Zones. AWS offers an Elastic IP Address feature that allows the cloud team to hide the failure of an ins.
