Using and configuring the Microsoft sync framework 2.1 for a real O.C.A

Standard

Editors note: Today’s article comes from one of my colleagues, Nic Cogotti, describing his experience in deploying the Microsoft Sync framework to synchronise a large customer database enabling an enterprise mobility scenario for one of UI Centric’s customers.

Whilst server-side logic has been a staple of cross platform development for decades, the often trumpeted feature of moving to the cloud is scalability.

In this piece I’ll be taking a look at the different options available in the Azure cloud for scaling services and infrastructure, and where they are most beneficial.
