Amazon EC2: An Extensive Guide to Instance Types

Introduction

Amazon EC2 (Elastic Compute Cloud) offers a wide range of instance types tailored to diverse use cases. These instance types vary in combinations of CPU, memory, storage, and networking capabilities. Understanding these options is crucial for optimizing your cloud infrastructure and cost efficiency.

Free Tier and Pricing Options

Amazon EC2 provides a free tier for experimentation and learning. For production use, you can choose from various pricing models, including:

• On-Demand Instances: Pay hourly or per second for compute capacity, with a minimum commitment of 60 seconds.
• Savings Plans: Commit to specific usage volume for up to three years and receive discounts.
• Reserved Instances: Purchase compute capacity for a fixed term (1-3 years) at a discounted rate.
• Amazon EC2 Spot Instances: Bid on spare compute capacity and get significant discounts.

The choice of pricing model depends on your usage patterns, cost constraints, and scalability requirements.

C5 Instances: Cost-Effective Performance

Amazon EC2 C5 instances provide a cost-effective solution for high-performance computing workloads. They offer:

• High compute-to-price ratio
