IaaS – AWS, Google and Microsoft

Choosing a Cloud Storage solution depends on several criteria: cost, accessibility, durability, scalability, flexibility and more. The Cloud Storage has several advantages and benefits over on premises storage, especially when it comes to cost and reliability. The Cloud Storage giants, namely Amazon S3 (Simple Storage Service), Microsoft Azure and Google Cloud Storage are constantly reducing costs, and innovating with more and more functionality.

The table below compares some of the fundamental Cloud Storage features provided by these three Cloud Storage giants.

Amazon S3 Microsoft Azure Google Cloud Storage
Reliability (durability & availability)
Stores data with up to 99.999999999% durability, with 99.99% availability. There can be no single points of failure. All failures must be tolerated or repaired by the system without any downtime Keeps 3 copies of objects within a single region, a geo-redundancy option can create 3 additional copies Delivers 99.9 percent or better uptime through its highly available, geo-redundant data-replication system
Can scale in terms of storage, request rate, and users to support an unlimited number of web-scale applications. It uses scale as an advantage: Adding nodes to the system increases, not decreases, its availability, speed, throughput, capacity, and robustness Up to 500 TB of total storage per account. A single subscription supports up to 50 storage accounts, delivering petabytes of storage for the largest scenarios You can store almost unlimited amounts of data and easily scale up or down
