Understanding Amazon EC2: Elastic Compute Cloud Fundamentals
Amazon Elastic Compute Cloud (EC2) is a web service provided by Amazon Web Services (AWS) that offers resizable compute capacity in the cloud. EC2 allows users to rent virtual servers known as instances to run applications. Key features include various instance types, Amazon Machine Images (AMIs), security groups, Elastic IPs, auto scaling, load balancers, Amazon EBS, regions and availability zones, instance lifecycle, and purchasing options. EC2 is widely used for web hosting, application hosting, data processing, machine learning, and more, providing scalability, flexibility, and cost-efficiency.

Elastic Compute Cloud (EC2) Amazon Elastic Compute Cloud (Amazon EC2) is a web service offered by Amazon Web Services (AWS) that provides resizable compute capacity in the cloud. EC2 allows users to rent virtual servers, known as instances, on which they can run their applications. These instances can be configured with various operating systems, such as Linux, Windows, and macOS, and are available in a variety of configurations to meet different computing requirements. Key features and concepts of Amazon EC2 include: Instances: These are the virtual servers that you can launch in the AWS cloud. You can choose from a wide range of instance types optimized for various use cases, such as compute-optimized, memory-optimized, storage-optimized, and GPU instances. Amazon Machine Images (AMIs): An AMI is a pre-configured template that includes an operating system and any additional software required to launch an instance. Users can choose from a range of public AMIs or create their own custom AMIs. Instance Types: EC2 offers various instance types optimized for different workloads. For example, the "t2.micro" instance type is suitable for low-traffic web servers or development environments, while the "c5.24xlarge" instance type is designed for high- performance computing. .

Elastic Compute Cloud (EC2) Security Groups: Security groups act as virtual firewalls for instances, controlling inbound and outbound traffic to and from instances. You can define rules to allow or deny specific types of traffic. Elastic IPs: Elastic IP addresses are static public IP addresses that can be associated with EC2 instances. They allow you to maintain a consistent public IP address even if you stop and start your instance. Auto Scaling: With Auto Scaling, you can automatically adjust the number of EC2 instances in a group based on demand. This helps ensure that your application can handle varying levels of traffic. Load Balancers: Elastic Load Balancing (ELB) distributes incoming application traffic across multiple EC2 instances to improve availability and fault tolerance. Amazon EBS: Amazon Elastic Block Store provides block-level storage volumes that can be attached to EC2 instances. EBS volumes are used for data storage and can be easily backed up and resized. Regions and Availability Zones: EC2 instances are available in multiple AWS regions and Availability Zones, allowing you to deploy your applications in data centers around the world for improved redundancy and performance. Instance Lifecycle: You can start, stop, terminate, and reboot EC2 instances as needed. Termination deletes the instance, while stopping and starting preserves the instance but may change its public IP address. . Mathiazhagan P -Assistant Professor - Computer Application Drsnsrcas
Elastic Compute Cloud (EC2) Instance Purchasing Options: You can choose between on-demand instances (pay-as-you- go), reserved instances (commitment-based savings), and spot instances (spare capacity at a lower cost). Amazon EC2 is widely used for various purposes, including web hosting, application hosting, data processing, machine learning, and more. It provides scalability, flexibility, and cost-efficiency, making it a popular choice for businesses and developers looking to run their workloads in the cloud. .
