Amazon Elastic Compute Cloud (EC2) vs. Amazon Elastic File System (EFS)

Suitable for companies that are looking for performance at a competitive price, flexibility to switch instance type even with RI, flexibility to add-on IOPS, option to lower running cost with the regular introduction of new instance type that comes with higher performance but at a lower cost.

While the idea is to utilize it enterprise wide; it sometimes doesn't work well in smaller applications and that causes slowdowns and impacts productivity. Also when evaluating EFS versus EBS - one needs to look at cost as EFS is a lot more expensive to implement and run so you need to weigh cost benefits of both systems and choose the best for you.

• Huge Diverse range of machine shapes are available which cater to our demand.
• Ability to combine the machines and integrate them with any other service in AWS (Ex: RDS, S3)
• Handling performance and scalability using auto-scaling, ELB configuration and high performance machine shapes.

• This is very easy to setup and has a great performance.
• As per the name, Elastic grows as your data grows.
• We can run multiple EC2 instances.

• The choices on AMIs, instance types and additional configuration can be overwhelming for any non-DevOps person.
• The pricing information should be more clear (than only providing the hourly cost) when launching the instance. AWS DynamoDB gives an estimated monthly cost when creating tables, and I would love to see similar cost estimation showing on EC2 instances individually, as not all developers gets access to the actual bills.
• The term for reserving instances are at least 12 months. With instance types changing so fast and better instances coming out every other day, it's really hard to commit to an existing instance type for 1 or more years at a time.

• For early age start it would be costly
• Not necessary for small scale system, but very beneficial for system which have high TPS and huge user base

You an start using EC2 instances immediately, is so easy and intuitive to start using them, EC2 has wizard to create the EC2 instances in the web browser or if you are code savvy you can create them with simple line in the CLI or using an SDK. Once you are comfortable using EC2, you can even automate the process.

AWS's support is good overall. Not outstanding, but better than average. We have had very little reason to engage with AWS support but in our limited experience, the staff has been knowledgeable, timely and helpful. The only negative is actually initiating a service request can be a bit of a pain.

The documentation is sufficient for setting up and it is basic NFS for mounting so not much support is required. I have not had any issues to warrant a request with AWS support.

Amazon EC2 is super flexible compared to the PaaS offerings like Heroku Platform and Google App Engine since with Amazon EC2, we have access to the terminal. In terms of pricing, it's basically just the same as Google Compute Engine. The deciding factor is Amazon EC2's native integration with other AWS services since they're all in the same cloud platform.

EFS is easier to configure, no need for Active Directory.

• It reduced the need for heavy on-premises instances. Also, it completely eliminates maintenance of the machine. Their SLA criteria are also matching business needs. Overall IAAS is the best option when information is not so crucial to post on the cloud.
• It makes both horizontal and vertical scaling really easy. This keeps your infrastructure up and running even while you are increasing the capacity or facing more traffic. This leads to having better customer satisfaction.
• If you do not choose your instance type suitable for your business, it may incur lots of extra costs.

Incentivized

• Cost is always a paramount issue when looking at ROI
• It is fast and if that's what you need for your implementation - you probably will not find a better solution
• Expertise in EFS is sometimes hard to come by so it's best to look at your employee's ability to grasp this technology. Otherwise, it's a pretty steep learning curve.
