But new technology is important because much of the world of information technology is based on file systems, but so far has not offered any AWS that are truly scalable storage leader says. EFS is the first of several AWS storage systems to work with multiple instances Elastic Compute Cloud (EC2), Amazon said in a FAQ online, and presentation of a gap in AWS offers.
"This is Amazon took a step closer to the real world, because there are many applications that are written to a file system rather than storing objects," said Jerome Lecat, CEO of storage company based in San Francisco Scality. "The reality of file systems today, and we must be able to ramp in modern storage technologies."
File systems that organize and manage file storage and retrieval, allow file locking and giving different users different permissions. So far, have been difficult to climb over some hundreds of thousands of files, Lecat said. By contrast, object storage can accommodate billions of files, but lacks the ability to monitor and control, and legacy applications must be rewritten to use - a task not trivial, he said.
EFS supports the case based solely on Linux, which disappointed Kevin Felichko, CTO of PropertyRoom.com, an online company the auction in Frederick, Maryland. The company has many instances of EC2 Windows.
"We have waited for EFS, and has now been released, this limitation is a disappointment, because we like to use," Felichko said. He said he expects and assumes Windows support will be forthcoming.
EFS is easy to configure and file storage on a large scale in the AWS cloud, Amazon said in today's announcement. Pointing and clicking AWS Management Console - or the command line or API - customers can use EFS to create file systems that are accessible to more instances Elastic Compute Cloud (EC2) simultaneously through the system network file (NFS) protocol, he said.
As the name suggests, EFS automatically scales storage customers to meet their files. File systems up to petabytes in size can be accommodated. EFS also automatically resizes debit transactions and input / output per second (IOPS) to meet customer performance requirements. Each file system can burst at least 100 MB per second, AWS said, and greater than 1 TB can go at a speed greater than the capacity of the file system grows
No wonder the beta lasted so long, Lecat said. "What has made AWS is very difficult. The creation of a highly scalable file system requires a completely different design."
EFS stores redundantly each file system in multiple availability zones, reducing the odds of failure. It can be used for a variety of workloads heavy flow, including large data, analysis, media processing, content management and Web services
EWS is an alternative to Elastic Block Storage (EBS), which provides low latency access AWS said, but only data from a single instance of EC2. It is also a widely used alternative to service single storage (S3) for storing objects, and Glacier, which is intended for the file.
Amazon announced EFS on top of AWS in San Francisco in April 2015. In June 2015, he said SAI would be available in the US East (Northern Virginia) and E.Ü. (Ireland) regions within two months, according to a report by TechTarget.
EFS is available immediately in the US East (Northern Virginia), US West (Oregon), and E.Ü. (Ireland) regions. AWS said it will expand to other geographical areas "in the coming months", but gave no details. Its price is 30 cents per GB per month, although customers in its first year in AWS receive up to five GB open month.
"Quite expensive, so companies with a large amount of data - for example, a petabyte or more - may choose to stay in place," observed Lecat.
