Naming Convention

  • m5.2xlarge

    • m: instance class

    • 5: generation (AWS improves them over time)

    • 2xlarge: size within the instance class

General Purpose

  • Greate for diverse workloads, webservers, code repos etc

  • Balance between

    • Compute

    • Memory

    • Networking

  • Instance class 'T' and 'M'

Compute Optimised

  • Great for compute-intensive tasks that need high performance processors

  • Use cases:

    • Batch processing workloads

    • Media transcoding

    • High performance web servers

    • High performance computing (HPC)

    • Scientific modeling & machine learning

    • Dedicated gaming servers

  • Instance class 'C'

Memory Optimised

  • 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 for BI

    • Applications performing real-time processing of big unstructured data

  • Instance class 'R', 'X', and 'Z'

Storage Optimised

  • 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 and NoSQL databases

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

    • Data warehousing applications

    • Distributed file systems

  • Instance class 'I', 'D', 'H'
