Amazon which promised to offer Elastic File System (EFS) in April last year has kept its promise now. Amazon’s EFS is now officially here and will be live for atleast three of Amazon’s cloud regions. With EFS Amazon customers can now access and store files hosted on the AWS cloud for multiple locations.
It’s official that Amazon’s EFS service will be available in the US West (Oregon), US East (Northern Virginia) and EU (Ireland).
Amazon EFS has the ability to work with multiple instances of EC2 even if the instances are in separate availability zones and this is what distinguishes its use from other cloud storage service offerings. The customers using EFS will only pay for the storage space they are using, as seen in other cloud offerings. Amazon believes that EFS will be handful aid in cases such as content management, media processing, big data and home directories.
Coming to Amazon web service offerings, EFS is not the only offering of Amazon. It already offers several types of data storage, including its flagship Simple Storage Service(S3), which makes any storage accessible from any device or application; Elastic Block Storage(EBS) which assigns storage to a given server and AWS Glacier, a cheaper way to store archival data which doesn’t need a faster access.
Till date AWS lacked IP Storage for workloads running on many servers. That comes in handy for widely distributed web applications that might need a ton of storage one second and not the next instance.
AWS EFS wants to differentiate its new offering from other public clouds with lower pricing and further expansions geographically. Amazon EFS has certain similarities with Microsoft’s Azure file storage and Google’s FUSE which is open source cloud storage. Customers using EFS will have a limit of 10 file systems for a particular AWS region. Also, a file can be opened simultaneously by a maximum of 128 user accounts.
