What are Compute Optimized EC2 Instances?

Compute-optimized instances are ideal for compute-bound applications that benefit from high-performance processors.

There are 2 types of compute-optimized instances available

• C4

• C5/C5n

1. C4 instances- These instances are optimized for compute-intensive workloads and deliver very cost-effective high performance at a low price-per-compute ratio.

   vCPU-> 2 to 36 Cores

   RAM-> 3.75 to 60 GB

   Storage-> EBS only

   Network Bandwidth-> 10Gbps

   UseCases-> Web Server, Batch Processing, MMO Gaming

2. C5/C5n instances- C5 are optimized for compute-intensive workloads and deliver cost-effective high performance at a low price per compute ratio. It is powered by AWS Nitro System.

   vCPU-> 2 to 72 Cores

   RAM-> 4 to 192 GB

   Storage-> EBS only & NVMe SSD

   Network Bandwidth-> Upto 25Gbps

   Use Cases -> High-Performance Webservers, Gaming, Video Encoding

   • C5 support max 25 EBS Volumes

   • C5 uses Elastic Network Adaptor

   • C5 uses new EC2 Hypervisor

**Note C3 instance is another instance that has been moved to the Previous Generation.
