Instance Types

Question 1

General Purpose

Answer 1

For diversity of workloads, such as web servers or code repositories

Balance between compute, memory and networking

Question 2

Compute Optimised

Answer 2

For compute intensive tasks, e.g.

• high performance computing (HPC)
• scientific modelling and machine learning
• dedicated gaming servers
• high performance web servers
• media transcoding
• batch processing workloads

Question 3

Memory Optimised

Answer 3

Fast performance for workloads that process large data sets in memory

• high performance relational and non-relational databases (in memory dbs)
• distributed web scale cache stores (elasticache)
• in-memory databases optimised for business intelligence (BI)
• Applications performing real-time processing of big unstructured data

Question 4

Storage Optimised

Answer 4

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

• High frequency online transaction processing (OLTP) systems
• Relational & NoSQL databases
• Cache for in memory databases (e.g. Redis)
• Data warehousing applications
• Distributed file systems
