EC2 Instance Types Basics

Question 1

Amazon EC2 Instance Types

Answer 1

• General Purpose
• Compute Optimized
• Memory Optimized
• Accelerated Computing
• Storage Optimized
• Instance Features
• Measuring Instance Performance

Question 2

Naming convention

Answer 2

m5.2xlarge

• m: instance class
• 5: generation (AWS improves them over time)
• 2xlarge: size within the instance class

Question 3

General Purpose

Answer 3

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

Balance between:
- Compute
- Memory
- Networking

tw.micro is a General Purpose EC2 instance

Question 4

Compute Optimized

Answer 4

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

C6g, C5, etc

Question 5

Memory Optimized

Answer 5

Fast performance for workloads that process large data sets in memory

Use cases:
- High performance, relational / non-relational databases
- Distributed web scale cache stores
- In-memory databases optimized for BI (business intelligence)
- Applications performing real-time processing of big unstructured data

R6g, R5, etc

Question 6

Storage Optimized

Answer 6

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
- Distributed file systems

I3, D2, H1, etc
