Why Use Amazon S3 for Cloud Storage?

Amazon Simple Storage Service, also known as Amazon S3 is an online storage facility. It is inexpensive, fast and easy to setup. Itís a service provided by e-commerce giant Amazon, so you can be rest-assured whatever you stored at S3 is secured. Even large file services like Dropbox use Amazon S3 as their back-end storage.

Inexpensive

In Amazon S3, thereís no initial charges or setup cost. You only pay for what you utilize, how much data you store and how much data you move in and out from the Amazon servers. Plus, upon sign-up, new Amazon customers receive 5 GB of Amazon S3 standard storage, 20,000 Get Requests, 2,000 Put Requests, and 15GB of data transfer out each month for one year. More details on Amazon S3 pricing can be found here.

Secure

Amazon S3 is built to provide infrastructure that allows the customer to maintain full control over who has access to their data. Customers are also able to easily secure their data in transit and at rest.

Reliable
