Hello everyone, let's delve into how to set up your first EC2 instance.
Amazon Elastic Compute Cloud (Amazon EC2) provides on-demand, scalable computing capacity in the AWS Cloud.
Using Amazon EC2 helps reduce hardware costs, allowing you to develop and deploy applications faster and more easily. With EC2, you can launch as many or as few virtual servers as you need, configure security and networking settings, and manage storage.
You can scale up capacity to handle compute-heavy tasks—like monthly or yearly processes, or spikes in website traffic—and when demand decreases, you can scale down accordingly.
An EC2 instance is essentially a virtual server in the AWS Cloud. When launching an EC2 instance, the instance type you select determines the hardware configuration available. Each instance type provides a unique balance of compute, memory, network, and storage resources, tailored to various workloads.
Features of Amazon EC2
Amazon EC2 offers several key features:
Instances: Virtual servers.
Amazon Machine Images (AMIs): Preconfigured templates that package everything you need for your server, including the operating system and additional software.
Instance types: Configurations of CPU, memory, storage, networking, and graphics hardware to meet different requirements.
Amazon EBS volumes: Persistent storage volumes via Amazon Elastic Block Store (Amazon EBS).
Instance store volumes: Temporary storage for data, deleted when you stop, hibernate, or terminate the instance.
Key pairs: Secure login information; AWS stores the public key, and you keep the private key.
Security groups: Virtual firewalls that control traffic to and from your instances, based on defined protocols, ports, and IP ranges.
Amazon EC2 also supports the processing, storage, and transmission of credit card data, validated for Payment Card Industry Data Security Standard (PCI DSS) compliance.
Related Services
Amazon EC2 works seamlessly with other AWS services to enhance functionality:
Amazon EC2 Auto Scaling: Automatically adjust the number of instances based on demand.
AWS Backup: Automate backups for EC2 instances and attached EBS volumes.
Amazon CloudWatch: Monitor your instances and EBS volumes.
Elastic Load Balancing: Distribute incoming traffic across multiple instances.

Additional Compute Services
If EC2 doesn’t suit your needs, AWS offers alternative compute services:
Amazon Lightsail: Ideal for quickly building websites or web applications, with a predictable monthly cost.
Amazon ECS (Elastic Container Service): Deploy and manage containerized applications.
Amazon EKS (Elastic Kubernetes Service): Run Kubernetes applications on AWS.
Accessing Amazon EC2
You can create and manage EC2 instances through several interfaces:
Amazon EC2 Console: A user-friendly web interface accessible via the AWS Management Console.
AWS Command Line Interface (CLI): Manage AWS services through your command-line shell (Windows, Mac, Linux).
AWS CloudFormation: Automate the provisioning of AWS resources using reusable templates in JSON or YAML.
AWS SDKs: Integrate EC2 functionality into your applications with language-specific APIs.
AWS Tools for PowerShell: Script operations on AWS resources using PowerShell.
Query API: Interact with EC2 through HTTP/HTTPS requests using the Query API.
Pricing for Amazon EC2
Amazon EC2 offers several pricing options:
Free Tier: Get started for free with limited resources.
On-Demand Instances: Pay by the second (with a 60-second minimum), no long-term commitments.
Savings Plans: Commit to a consistent usage level to reduce costs over 1 or 3 years.
Reserved Instances: Prepay for a specific instance configuration to save on costs.
Spot Instances: Purchase unused EC2 instances at reduced prices.
Dedicated Hosts: Use a physical EC2 server dedicated to you, available On-Demand or through a Savings Plan.
On-Demand Capacity Reservations: Reserve compute capacity in specific Availability Zones.
Per-second Billing: Only pay for the time your instance is active.
