EC2 Instance

EC2 인스턴스 타입 (https://aws.amazon.com/ec2/instance-types/)

- General Purpose

- Compute Optimized

- Memory Optimized

- Accelerated Computing

- Storage Optimized

- Instance Features

- Measuring Instance Performance

 

m5.2xlarge

▶ m : instance class

▶ 5 : Generation (AWS improves them over time)

▶ 2xLarge : size within the instance class

 

● General Purpose

- Great for a diversity of workloads such as web servers or code repositories

- Balance between :

   - Compute

   - Memory

   - Networking

- T2.micro is a General Purpose EC2 Instance

 

● Compute Optimized

- Great for compute-intensive tasks that require high performance processors:

   - Batch processing workloads

   - Media transcoding

   - High performance web servers

   - High performance computing (HPC)

   - Scientific modeling & machine learning

   - Dedicated gaming servers

 

● Memroy Optimized

- Fast performance for workloads that process large data sets in memory

- Use cases:

    - High performance, relational/non-relational databases

    - Distributed web sacle cache stores

    - In-memory databases optimized for BI (Business Intelligence)

    - Applications performing real-time processing of big unstructured data

 

● Storage Optimized

- Great for storage-intensive tasks that require high, sequential read and write access to large data sets on local storage

- Use cases:

    - High frequency online transaction processing (OLTP) systems

    - Relational & NoSQL databases

    - Cache for in-memory databases (for example, Redis)

    - Data warehousing applications

    - Distrubuted file systems
