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.

For archiving old data that is infrequently accessed it is perfect. You can choose to let it go into cold/glacier storage which saves even further costs but at the expense of accessibility. I like that you can set access rules to automatically move it to the next storage tier after a certain amount of time that it has not been accessed. I also use it a lot with PHP via the API. We have some custom in-house applications that have a fair amount of data uploaded into them. S3 has been a perfect solution to store these files, taking the load off web servers and never having issues with running out of storage.

Pros
  • A great variety of choices in Amazon Machine Image (AMI) types. Users can select a more basic type to run generic workloads, but also have the choice to pick an AMI pre-installed with specific services in the AWS Marketplace.
  • The range of instance types can support the usage from a student's exploration (inexpensive general-purpose nano instances) to an enterprise's most intense workloads (memory or storage-optimized instances with terabytes of memory and ultra-fast network connection).
  • The pricing options, from regular instances, reserved instances to spot instances allow users to get the job done and make smart choices about how much they want to pay and when they want to pay.

  • Reliable and secure way to store objects in cloud: Storing any type of file(text, pdf, doc, csv, etc) is very easy with S3. Fetching this stored content as and when you require is also pretty easy and can be done using both the console and AWS CLI. Appropriate permissions can be set up for buckets using IAM roles/policies.
  • Versioning in buckets: S3 gives you a very handy feature to store multiple versions of objects stored in a bucket.
  • Lifecycle policies: You can set up lifecycle policies in S3 that can move your older objects to IA or Glacier. This setup is very easy and can be done within minutes for a bucket.
  • Replication: The cross-region replication that S3 provides is wonderful. Beware of the inter-regional data transfer costs though.

Cons
  • This service is a bit difficult to consume. New users need a big learning curve to use this service effectively.
  • UI for EC2 service is a little complex and at many places, it misses detailed explanation.
  • Sometimes it takes too long to create images of EC2 instances. This keeps your EC2 up for that extra time. When instances are heavy, it penalizes a lot of money.
Read full review
  • The biggest problem is to rename the bucket. There is no direct way to do it. One need to copy entire content to the different bucket with intended bucket name and then remove the old bucket. Sometimes it creates issues.
  • There is no direct way to upload .zip file and extract it to inside the bucket.
  • While uploading large files, sometimes you will find a drop of upload speed. I observe it so many times and while checking my internet speed, I find it absolutely perfect. So there must have something wrong on the AWS side.

Usability
It's easy and straightforward for a technical person to use it via SSH, but when working in cross-functional teams, using Amazon's web console is difficult for this particular service. Most modern cloud providers provide a more seamless user interface to interact with their cloud machines, and the same should have been the case with EC2.
Read full review
The UI could have some improvements (better filters) and there is a lack of some useful functionality, such as renaming an existing bucket: the latter is much needed in the context of rapidly evolving companies. Overall though, Amazon S3 (Simple Storage Service) is easy to use and to onboard people and tools to, thanks to its various APIs and flexibility.

Support Rating
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.
Read full review
It depends on your tier within Amazon on how great of support you get. For us we have a dedicated Point of Contact that is great in taking in what we need and discussing it with the S3 team. The best thing is features we need or suggest have a good chance of landing on their roadmap.

Azure VM Builder offers good service, but the options are quite limited (Too much inclined to Windows as it is prepared by Microsoft).

S3 is the most mature simple storage service on the web. It has direct competitors from Google and Azure, as well as a bunch of other competitors that focus on different aspects. For example, Backblaze specializes on file backups, and while s3 can also be used for that, Backblaze provides a better price point in exchange for more focused functionality. S3 really shines in that it performs simple things astonishingly well, while also being flexible enough to stretch itself to other situations (data lakes, file mounts, backup/restores systems, web hosting, etc.).

Return on Investment
  • With EC2 you pay only when is Running, so you can save up to 75% on Dev environments which are running only on office hours
  • You have several ways to pay for EC2, with EC2 Reserved Instances you pay with a discount of up to 72% if you make a commitment of using them from 1 or 3 years
  • With EC2 spot you can use spare AWS EC2 capacity with a discount of up to 90%, your workload must be interrupt tolerant as your EC2 could be reclaim by AWS and the EC2 terminated
