What is the memory limit for Lambda functions?
In AWS Lambda, memory allocation determines not only the amount of RAM available to the function but also the proportionate CPU and network throughput. You can configure the memory allocation in 1 MB increments starting from 128 MB up to 10,240 MB (10 GB). Choosing higher memory results in better performance and faster execution times.
Key Details About Lambda Memory Limits
Minimum memory allocation: 128 MB
Maximum memory allocation: 10,240 MB (10 GB)
Configurable in 1 MB increments
CPU power and network throughput increase with memory
Memory impacts cost (more memory = higher price per millisecond)
