One of the basic challenges in dealing with multiple instances in Windows Azure is managing concurrency. For example, consider a scenario where you need to keep an accurate count at scale. With many simultaneous requests coming to many role instances all updating the same number, the difficulty arises in making sure that number is correct and that the writers don’t spend a lot of time retrying after concurrency failures.
Join Wade Wegner, CTO at Aditi Technologies and former Director of Windows Azure Technical Evangelism at Microsoft, as he talks through this problem and provides a solution for managing concurrency across multiple role instances in Windows Azure.
Wade is currently the CTO at Aditi Technologies, where he is responsible for driving Aditi’s technical strategy and ensuring continuous innovation on behalf of its customers. Prior to joining Aditi, Wade held several roles in Microsoft, most recently leading Technical Evangelism for Windows Azure.
