📌Overview of service:
Amazon EC2 (Elastic Compute Cloud) provides virtual servers, called instances, that allow users to run applications in the cloud without owning physical hardware. With EC2, developers can quickly launch servers, configure them as needed, and scale them up or down based on demand.
EC2 removes the need for upfront hardware investment and gives full control over computing resources.
⭐Key Features of Amazon EC2:
Some important features of Amazon EC2 are:
● Scalable compute capacity – increase or decrease instances anytime
● Multiple instance types – optimized for compute, memory, or storage
● Flexible operating systems – supports Linux, Windows, and more
● High availability – deploy instances across multiple Availability Zones
● Security – integrated with IAM, security groups, and key pairs
🗂️AWS Category / Cloud Domain:
* Amazon EC2 belongs to the Compute category in AWS.
* Cloud Domain: Virtual Servers / Compute Infrastructure
🔄Where Amazon EC2 Fits in the Cloud / DevOps Lifecycle:
Amazon EC2 is used throughout the application lifecycle:
● Development – test and build applications
● Deployment – host web servers and backend services
● Scaling – handle increased traffic using auto scaling
● Operations – monitor and maintain running applications
● Disaster Recovery – launch instances from backups when needed
💻Programming Languages & Access Methods:
Amazon EC2 can be accessed using:
● AWS Management Console
● AWS CLI
● AWS SDKs, such as:
● Python (Boto3)
● Java
● JavaScript (Node.js)
● C#
● REST APIs
These options allow easy automation and integration with DevOps tools.
💰Pricing Model:
Amazon EC2 follows a pay-as-you-go pricing model. Pricing depends on:
● Instance type (CPU, memory, storage)
● Running time (per second or per hour)
● Pricing option, such as:
● On-Demand
● Reserved Instances
● Spot Instances
There is no long-term commitment for on-demand usage.
✅Conclusion:
Amazon EC2 is the foundation of many cloud applications and services. Its flexibility, scalability, and wide range of configuration options make it ideal for hosting everything from small websites to large enterprise systems. Learning EC2 is a key step in understanding AWS and cloud computing.
