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.


Sia


Decentralized storage service Sia has been around since 2014, originally incorporated as Nebulous Inc.

Sia launched their Cryptocurrency by the end of 2015. Early investors have since seen an incredible increase of the currencies value by over 18.000 times the initial price. Before launching their Cryptocurrency a Whitepaper was published with details on how Nebulous/Sia expected to see the network grow, describing their storage capacity algorithm and more.

Sia uses smart contracts to ensure SLAs on uptime, pricing and more. Sia is open source and written in Golang.
