Amazon EC2 allows businesses to run virtual machines in AWS data centers, providing scalable compute capacity. Developers can launch EC2 instances running various operating systems and application programs. Instances can be increased or decreased on demand or through reserved contracts. EC2 offers multiple instance types optimized for different workloads. Developers pay hourly for on-demand instances or get discounts with 1-3 year reserved contracts. EC2 provides easy scaling but developers must manage resources and security across many instances.

Amazon EC2 (Elastic Compute Cloud) Presented by Subham Mukherjee BWU/BTS/19/037
Introduction Amazon Elastic Compute Cloud (Amazon EC2) is a web-based service that allows businesses to run application programs in the Amazon Web Services. Amazon EC2 allows a developer to spin up virtual machines, which provide compute capacity for IT projects and cloud workloads that run with global AWS data centers. An AWS user can increase or decrease instance capacity as needed within minutes using the Amazon EC2 web interface or an application programming interface (API).
How EC2 works ? To begin using EC2, developers sign up for an account at Amazon's AWS website. They can then use the AWS Management Console, the AWS Command Line Tools (CLI), or AWS Software Developer Kits (SDKs) to manage EC2. A developer then chooses EC2 from the AWS Services dashboard and 'launch instance' in the EC2 console. At this point, they select either an Amazon Machine Image (AMI) template or create an AMI containing an operating system, application programs, and configuration settings. The AMI is then uploaded to the Amazon S3 and registered with Amazon EC2, creating an AMI identifier. Once this has been done, the subscriber can requisition virtual machines on an as-needed basis. Data only remains on an EC2 instance while it is running, but a developer can use an Amazon Elastic Block Store volume for an extra level of durability and Amazon S3 for EC2 data backup. EC2 also offers Amazon CloudWatch which monitors Amazon cloud applications and resources, allowing users to set alarms, view graphs, and get statistics for AWS data; and AWS Marketplace, an online store where users can buy and sell software that runs on AWS.
Amazon EC2 instance types Instances allow developers to expand computing capabilities by 'renting' virtual machines rather than purchasing hardware. An EC2 instance is used to run applications on the Amazon Web Services infrastructure. Amazon EC2 provides different instance types, sizes and pricing structures designed for different computing and budgetary needs. In addition to general purpose instances, Amazon EC2 offers an instance type for compute, memory, accelerated computing, and storage-optimized workloads. AWS limits how many instances a user can run in a region at a time, depending on the type of instance. Each instance type comes with different size options corresponding to the CPU, memory and storage needs of each enterprise.
Cost On-Demand instances allow a developer to create resources as needed and to pay for them by the hour. Reserved instances (RIs) provide a price discount in exchange for one and three- year contract commitments -- a developer can also opt for a convertible RI, which allows for the flexibility to change the instance type, operating system or tenancy. There's also an option to purchase a second-hand RI from the Amazon EC2 reserved instances marketplace. A developer can also submit a bid for spare Amazon EC2 capacity, called Spot instances, for a workload that has a flexible start and end time.
Benefits 6 Getting started with EC2 is easy, and because EC2 is controlled by APIs developers can commission any number of server instances at the same time to quickly increase or decrease capacity. EC2 allows for complete control of instances which makes operation as simple as if the machine were in-house. The flexibility of multiple instance types, operating systems, and software packages and the fact that EC2 is integrated with most AWS Services -- S3, Relational Database Service (RDS), Virtual Private Cloud (VPC) -- makes it a secure solution for computing, query processing, and cloud storage.
Challenges 7 Resource utilization -- developers must manage the number of instances they have to avoid costly large, long-running instances. Security-- developers must make sure that public facing instances are running securely. Deploying at scale -- running a multitude of instances can result in cluttered environments that are difficult to manage. Management of AMI lifecycle -- developers often begin by using default Amazon Machine Images. As computing needs change, custom configurations will likely be required. Ongoing maintenance -- Amazon EC2 instances are virtual machines that run in Amazon's cloud. However, they ultimately run on physical hardware which can fail
