What do the EC2 instance type naming conventions mean?

EC2 instance names follow the pattern [family][generation][attributes].[size]. For example, m7g.xlarge means general purpose (m), 7th generation, Graviton processor (g), with xlarge sizing (4 vCPUs, 16 GB RAM). Common family prefixes: c=compute, m=general, r=memory, t=burstable, p/g=GPU.

Should I choose Graviton instances?

Graviton (ARM-based) instances like m7g and c7g typically offer 20-40% better price-performance than equivalent x86 instances. They work well for containerized workloads, web servers, and applications compiled for ARM. Check that your software stack supports ARM/aarch64 before migrating.

What is the difference between on-demand and spot pricing?

On-demand instances are billed per second with no commitment and can run indefinitely. Spot instances use spare AWS capacity at up to 90% discount but can be interrupted with two minutes notice. Use spot for fault-tolerant workloads like batch processing, CI/CD, and stateless containers.

About This Tool

The EC2 Instance Match Helper finds the right Amazon EC2 instance type based on your workload requirements. Specify your minimum vCPU count, memory, storage type, network performance, and processor preferences, and the tool filters AWS's extensive instance catalog to show matching options sorted by price. It covers all current-generation instance families including general purpose, compute optimized, memory optimized, storage optimized, and accelerated computing.

When to Use This Tool

•Finding the most cost-effective instance type for a Java application server that needs at least 8 vCPUs and 32 GB of memory.
•Identifying GPU instances suitable for machine learning training workloads with specific CUDA requirements.
•Comparing Graviton (ARM) vs. Intel vs. AMD instances for a containerized microservice to optimize price-performance.
•Selecting an instance family for a memory-intensive Redis or Elasticsearch cluster.
