What is AWS EFS?
EFS(Elastic file system) is a file-level storage service that basically provides a shared elastic file system with virtually unlimited scalability support. EFS is highly available storage that can be utilized by many servers at the same time. AWS EFS is a fully managed service by amazon and it offers scalability on the fly. This means that the user need not worry about their increasing or decreasing workload. If the workload suddenly becomes higher then the storage will automatically scale itself and if the workload decreases then the storage will itself scale down. This scalability feature of EFS also provides cost benefits as you need not pay anything for the part of storage that you don’t use, you only pay for what you use(Utility-based computing).
One most important feature of EFS that makes it different from all other storage is that the IOPS rate in EFS is inversely proportional to the size of data. For example, if the size of data is less, then the performance and IOPS rate might be not much significant but when used more heavily, EFS can offer as much as 10 GB/sec along with 500,000 IOPS.
