Descriptions

Amazon S3

World’s biggest Cloud Storage Provider. Amazon, traditionally an online book store, has put a target on the cloud compute space when it shifted its focus to Amazon Web Services (AWS) in 2006. E-Commerce competition was tough, but public cloud companies back then were scarce, and usability and user friendly products were a long way from being invented.

Amazon’s reign on cloud computing has left its mark in public cloud-land. Competitors have trouble keeping up, if they even get to a point of feature-parity at all. With Amazon’s S3 storage being one of the first, it has basically dictated a standard for the public cloud’s blob storage protocol.

Needless to say, Amazon invented the S3 (Simple Storage Service) standard.

Azure Storage

Microsoft Azure Cloud Storage Microsoft’s answer to their cloud competitor Amazon is finally here. Microsoft has a wide range of storage solutions, providing SaaS (software as a service), PaaS (platform as a service ) and IaaS (infrastructure as a service). Azure supports a great variety of programming languages, tools, and frameworks, ranging from Microsoft-specific to Linux, or other third-party software and systems.

In the table below we’ll look at the Hot Access Tier, as this is the most commonly used storage tier for online usage.
