Amazon EFS (Elastic File System) Review

A fast, stable, and scalable solution with flexible pricing and good elasticity

What is our primary use case?

I'm a consultant, and I architect solutions for customers by using Amazon EFS in other Amazon products. I am using EFS based on NFS version 4.

I have a customer who is using around 20 Linux servers hosting MySQL databases. Their storage is in Amazon EFS. So, around 20 Linux servers are connecting to Amazon EFS.

How has it helped my organization?

Before Amazon EFS, our customer was using EBS volumes in a unique EC2 instance to serve NFS servers. Now, these EC2 instances are not necessary. The productivity of the customer has improved by around 30% by using Amazon EFS instead of a unique EC2 NFS instance.

What is most valuable?

Its elasticity and flexible pricing are the most valuable. For Amazon EFS, you are charged based on the storage. It is also very fast and stable with a very simple and intuitive interface.

What needs improvement?

It could be better in connecting with Windows Server instances.

For how long have I used the solution?

I have been working with Amazon EFS for around two years.

What do I think about the stability of the solution?

Its stability is wonderful. Our customers are very grateful because it has been working successfully in a very much acceptable way.

What do I think about the scalability of the solution?

Its scalability is great. It is very fast. It is almost instantaneous. Our customers are small and medium business companies.

How are customer service and technical support?

For this project, we did not need support. We didn't use professional or paid support. Amazon's documentation is very rich and helped us during this project.

Which solution did I use previously and why did I switch?

Our clients didn't know any other solution like this. We, as IT consultant, offered the solution to the clients.

How was the initial setup?

The initial setup is straightforward. 

What's my experience with pricing, setup cost, and licensing?

It has flexible pricing. You are charged based on your storage.

What other advice do I have?

It a great scalable and stable solution, but just use Unix or Linux servers on-premises or in the Amazon cloud. I won't recommend using a Network File System to connect to Windows Servers.

I would rate Amazon EFS a nine out of ten.
