Amazon Web Service EC2 (Amazon Elastic Compute Cloud), one of Amazon Web Services' most well-known services, offers businesses the ability to run applications on the public cloud. An EC2 instance is simply a virtual server in Amazon Web Services terminology. With an EC2 instance, AWS subscribers can request and provision a computer server within the AWS cloud.
Amazon has several product offerings. Here we'll quickly describe the differences between EC2 and other AWS products like S3 and ECS.
EC2 and S3: Where EC2 is like a remote computer running Windows or Linux, S3 is simply a storage service for storing large binary files.
EC2 and Amazon EBS: Amazon Elastic Block Store (Amazon EBS) provides block-level storage volumes for an EC2 instance.
EC2 and AWS Lambda: AWS Lambda can be considered an EC2 Container Service (ECS) framework that uses containers to run a piece of code representing your application.
EC2 and Amazon RDS: Amazon Relational Database Service (Amazon RDS) database instances are similar to Amazon EC2 instances because there are different families to suit different workloads. RDS automatically manages time-consuming tasks, such as configuration, backups, and patches, and the Amazon EC2 cloud computing platform lets you create as many virtual servers as you need.
EC2 and Amazon CloudWatch: The CloudWatch agent collects metrics and logs from Amazon EC2 instances and on-premises servers.
EC2 and Amazon Linux AMI: The Amazon Linux AMI is a supported and maintained Linux image provided by Amazon Web Services for use on Amazon Elastic Compute Cloud (Amazon EC2).
Developers can create virtual machine instances and easily configure models' capacity scaling using the EC2 web interface. An Amazon EC2 instance also allows users to build apps to automate scaling according to changing needs and peak periods. It makes deploying virtual servers and managing storage simple, requiring less hardware and helping streamline development processes
EC2 pricing depends on the hours and size of an instance, region, and operating system
EC2 setup involves creating an Amazon Machine Image (AMI), which includes an operating system, apps, and configurations. That AMI is loaded to the Amazon Simple Storage Service (S3) and registered with EC2. Users can then launch virtual machines as needed.
Amazon offers different instance types of EC2 for varying requirements and budgets in the AWS Marketplace, including hourly, reserved, and spot rates.
AWS has a limit of 20 instances per region.
Stopped EC2 instances do not incur any charges. However, you will be charged for Elastic IP addresses, EBS volume, or used S3 storage. You'll want to pause or delete these services to mitigate extra charges.
Connecting to your AWS EC2 console is very straightforward. You'll want to:
Begin by opening your Amazon EC2 console
Choose the instance that you want to connect to
Adding EBS volume to your EC2 instance is done in 4 steps.
In EC2, select Volumes
Choose your preferred size and type
Select your newly created volume, and right-click to attach the volume

You can resize instances in Amazon EC2 if the new instance types are compatible by:
Virtualization-type Linux AMIs are paravirtual (PV) or hardware virtual machines (HVM). You cannot resize an instance launched as a PV to an instance of HVM.
Architecture New instance types can only launch to the same processor architecture. For example, 32-bit AMIs can only resize to other 32-bit instances.
Network You cannot resize to an EC2-Classic from newer instance types. More unique instance types must launch in a VPC.
Enhanced networking requires necessary drivers, and you cannot resize to an instance that does not support them.
NVMe To resize to instances that use NVMe, you must first install the NVMe drivers on your existing instance.
Several benefits and features draw developers to EC2 for cloud computing. Chief among these are:
Responsiveness to changing capacity requirements: The easy scaling of EC2 eliminates development obstacles when applications require more resources.
Flexibility in configurations: Users can choose memory size, CPU, and boot partition size optimized for their OS.
Integration: EC2 can integrate with other AWS services, such as RDS, SimpleDB, and SQS.
Precise control: Users get administrative access to their instances, can stop and start instances while retaining boot partition data, and can access console output for the instance.
Security: Users can control which instances remain private and have internet exposure. EC2 leverages Amazon Virtual Private Cloud (VPC) for security, and businesses can connect their secure IT infrastructure to resources in VPC.
Cost: Among several pricing options, EC2 offers affordable hourly rates.
AWS provides an auto-scaling group service designed to provide automatic scalability for its various services, including EC2. Autoscaling ensures that you have enough EC2 instances to run applications, and before running a service, you designate autoscaling groups. These groups can have a minimum or a maximum number of EC2 instances that kick in automatically if an instance has an error or failure.
CPU credits are a form of currency that allows T2 instances to expand CPU performance beyond the standard baseline of EC2. T2 instances earn CPU credits every hour, equaling one full minute of the full CPU core. Once your T2 instance runs out of CPU credits, its performance reduces to the limited baseline.
EC2 has several benefits. One of the main benefits of AWS EC2 is its elastic load balancing, which automatically distributes incoming application traffic across several instances while identifying unhealthy instances, and reroutes traffic to the healthy versions until restored.
Additional benefits include:

The EC2 Container Service (ECS) uses EC2 instances for a quick and easy way to set up and scale a container cluster. Doing this removes the headaches involved with managing an internal cluster management infrastructure and makes it simple to establish containers as the foundation of an application. Explore the Sumo Logic app for real-time analysis of ECS data, which provides metrics collection from the instances of your choice.
Like EC2, the ECS service is easy to scale, so it can readily adapt to an application's changing capacity needs. It allows for scheduling ongoing batch processes, services and applications and offers integration through its API with other AWS products and external programs.
