About this tool
AWS Service Quota Reference
The AWS Service Quota Reference provides default limits, adjustability status, and scaling considerations for commonly encountered AWS service quotas.
• Check Lambda concurrent execution limit before scaling a high-throughput function
• Find EC2 vCPU limits for your instance family before a capacity planning review
• Look up RDS instance limits before deploying a microservices database fleet
• Identify which S3 limits are hard vs adjustable before architecting a multi-tenant system

FAQ
What does this tool tell you?
The AWS Service Quota Reference provides default limits, adjustability status, and scaling considerations for commonly encountered AWS service quotas.
What affects the result most?
EC2 service quotas: vCPU limits per instance family (Running On-Demand Standard instances default 32 vCPU). Lambda concurrent executions: default 1000 per region — most common Lambda scaling failure cause. S3: no bucket count limit per account, 5TB max object size, 100 parts max for multipart.
How should I use the result?
Use this tool to orient quickly to the concepts, field names, or values you are about to look up in a full specification or vendor documentation. It summarizes the common cases; the authoritative source remains whichever standard or vendor doc defines the values themselves.
