Introduction to EC2 Instance Types ๐Ÿ”๐Ÿ”ง

Diverse Instances for Different Demands:

  • AWS offers a variety of EC2 instances optimized for distinct use cases.

  • Naming Convention: e.g., m5.2xlarge, where 'm' is the instance class, '5' is the generation, and '2xlarge' signifies the size within the class.

EC2 Instance Types - General Purpose ๐ŸŒโš–๏ธ

Ideal for Versatile Workloads:

  • Suited for diverse workloads like web servers or code repositories.

  • Balanced resources: Compute, Memory, and Networking.

  • Example: t2.micro โ€“ a General Purpose EC2 instance used in the course.

EC2 Instance Types - Compute Optimized ๐Ÿ’ก๐Ÿ’ป

Powering Compute-Intensive Tasks:

  • Tailored for tasks demanding high-performance processors.

  • Use Cases:

    • Batch processing workloads.

    • Media transcoding.

    • High-performance web servers.

    • Scientific modeling, machine learning, and dedicated gaming servers.

EC2 Instance Types - Memory Optimized ๐Ÿš€๐Ÿ“Š

Fast Performance for Memory-Intensive Workloads:

  • Designed for tasks processing large datasets in memory.

  • Use Cases:

    • High-performance relational/non-relational databases.

    • Distributed web scale cache stores.

    • In-memory databases optimized for BI (business intelligence).

    • Real-time processing of big unstructured data.

EC2 Instance Types - Storage Optimized ๐Ÿ“ˆ๐Ÿ“š

High-Performance Storage-Intensive Tasks:

  • Suited for tasks requiring high, sequential read and write access to large datasets on local storage.

  • Use Cases:

    • High-frequency online transaction processing (OLTP) systems.

    • Relational & NoSQL databases.

    • Cache for in-memory databases (e.g., Redis).

    • Data warehousing applications.
