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.
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)
