1. Introduction to Amazon EC2
Amazon Elastic Compute Cloud (EC2) is a core AWS service that provides resizable, secure, and scalable compute capacity in the cloud. It allows businesses to deploy virtual servers (instances) on demand, reducing the need for physical hardware and offering flexible pricing models.
2. Key Features of Amazon EC2
a. Elasticity & Scalability
- Easily scale instances up or down based on demand.
- Auto Scaling groups ensure high availability and cost efficiency.
b. Multiple Instance Types
- EC2 offers various instance types optimized for compute, memory, storage, and GPU processing, catering to different workloads.
c. Security & Compliance
- Secure networking with Virtual Private Cloud (VPC) integration.
- IAM roles, Security Groups, and encryption options for enhanced data protection.
d. Flexible Pricing Models
- On-Demand: Pay only for the instances you use.
- Reserved Instances: Significant cost savings for long-term commitments.
- Spot Instances: Up to 90% savings for flexible workloads.
e. High Availability & Reliability
- Multi-region and multi-AZ (Availability Zone) deployments ensure uptime.
- Elastic Load Balancing (ELB) distributes traffic across multiple instances.
f. Operating System (OS) Support
- Supports Linux, Windows, macOS, and custom AMIs (Amazon Machine Images).
3. Amazon EC2 Instance Types
AWS provides different EC2 instance families, each designed for specific workloads.
| Instance Family | Use Case |
|---|---|
| General Purpose (T, M series) | Balanced workloads (web servers, microservices) |
| Compute Optimized (C series) | High-performance computing (HPC), gaming servers |
| Memory Optimized (R, X series) | Big data analytics, in-memory databases |
| Storage Optimized (I, D series) | High-speed storage workloads, NoSQL databases |
| GPU Instances (G, P series) | AI/ML training, deep learning, graphics rendering |
4. Amazon EC2 Pricing Models
a. On-Demand Instances
- Pay-as-you-go pricing.
- Ideal for short-term, unpredictable workloads.
b. Reserved Instances (RI)
- 1-year or 3-year commitment with up to 75% discounts.
- Best for steady-state workloads with predictable usage.
c. Spot Instances
- Unused EC2 capacity available at up to 90% discount.
- Suitable for batch processing, big data, and fault-tolerant applications.
d. Dedicated Hosts & Dedicated Instances
- Provides physical servers for compliance-heavy workloads.
