Great cloud storage solution but a little cumbersome to set up for notice users.

Amazon S3 (Simple Storage Service)
2 years of experience
Use Cases and Deployment Scope
We are using Amazon S3 as an online repository for online backups. This addresses the needs of having data stored offsite with multiple layers of redundancy.
Pros
  • Security - S3 is great at encrypting traffic at rest and in transit.
  • Integration - S3 works great with multiple applications which is great for us since we don't have to be married to a partciluar software solution for online backups.
  • Billing - Easy to read and straight forward for clients.
Cons
  • Ease of use - Pretty difficult to setup if you aren't in the industry. Not something a notice user can setup without spending some time with it.
Likelihood to Recommend
S3 is well suited for anyone that wants to store data in the "cloud" and not be so expensive. This is beneficial for individuals that have a lot of data to store.

Storage, yes, but simple. Not for everyone.

Use Cases and Deployment Scope
We use Amazon's Simple Storage Service to store both static and somewhat dynamic assets. It is used in conjunction with Amazon's CloudFront service. It is a simple, cost-effective way to serve assets across our web apps, mobile apps, and websites. It solves the problem of reliable distribution at an affordable price, all wrapped up in a scalable solution. Between our various properties, we distribute over 1TB of data per month across millions of instances.
Pros
  • Scalable
  • Reliable
  • Well documented
Cons
  • Hard to use
  • Not for non-developers
  • Bad online UI
Likelihood to Recommend
S3 is a VERY quick way to get up and running. Very simple for developers to use and have work. With the rest of Amazon's offerings, it can scale to be distributed via CDN, replicated, etc. If you need non-developers to store/update, though, this may not be the solution for you. The UI is far too confusing and easy to make a mistake on, and if you use CloudFront you need to invalidate, etc. with new uploads which is hard to grasp as a non-developer. As well, other companies have far less expensive solutions which scale just as well.

We are happy with AWS S3

Use Cases and Deployment Scope
We use S3 to store files that we offer to subscriber customers.
Pros
  • Scales automatically.
  • Is always available.
  • Is cost effective with different storage tiers.
Cons
  • Slow access.
  • Difficult to manage files on large repositories.
  • Users are locked on it as migration to other services isn't easy or cheap.
Likelihood to Recommend
Very well suited to storing files that have a long "shelf life." Less suited if you need to move then (download or upload) multiple times because you pay for bandwidth.

Use Cases and Deployment Scope
We are currently using S3 for off-site storage of backup data using a variety of backup client software. We utilize multiple Amazon sites for redundancy when needed. Some data is stored in our account using our software for our clients, and some data is stored in the client's account which we manage.
Pros
  • Multiple security access levels ensure that one client cannot access another clients data.
  • Multiple geographic locations allows us to meet certain audit requirements.
  • Simple setup from within many cloud backup clients.
Cons
  • Security configuration can be a little confusing and sometimes requires making completely new accounts.
Likelihood to Recommend
Amazon S3 meets many of the demands for cloud based backup including some audit requirements for various DoD, HIPAA, and PCI restricted businesses. We store data with various levels of encryption and redundancy for our clients as required by their industry. There are also less expensive options, such as Glacier, in cases where audit compliance is not an issue.

Use Cases and Deployment Scope
We are currently using S3 in two different areas of the company, the first is to store backups for our WordPress websites, we have 10 different sites so each site has an automated process where every day they upload critical framework data to the different files I set up on S3. The second area where we use it is for archiving of BLOB's from our escrow software. The software saves documents which are used in the escrow in BLOB format. Using the automated process in the escrow software every sixty days the BLOB's are uploaded into the S3 folder setup for it.
Pros
  • Once set up it is as simple as pointing to it and it works.
  • It is fast for putting data on it and taking it off.
  • It allows a mixture of data types which makes it ideal for how we use it; we don't have to worry that it would store a data type.
Cons
  • If you're not a network type and don't understand terms like DNS or routing then it's going to be hard to get it setup correctly. They need to make this process a little more user-friendly for people that are not IT types.
  • They should make security more friendly currently you have to have a very good understanding of what your setting so that the outside world does not see all of your data, a security preview would be great also to make sure the security setting is performing correctly.
  • Billing is another area which could use some help in making it friendlier, you have to spend a lot of time doing deep dives on your bill to understand why cost just seems to have gone up.
Likelihood to Recommend
Amazon S3 is well suited for any applications which need to store documents, pictures, video either pre/post-processing or BLOB's/CLOB's. The reason for that is once you set everything up it is easy to point to and it is fast to get and store items on it with no worries. Plus with the redundant backup's it is secure. The other great feature is if you're using other AWS it is extremely easy to connect to S3 and the speed is even better since it is on their own network.
