Cisco & Azure Stack
Up to this point, we have known that there would be 3 hardware vendors - Dell, HPe & Lenovo - who would be ready to provide customers with solutions to deploy Azure Stack when it becomes GA later this year. It was always likely that other vendors would follow and as we can see from the following blog post - https://blogs.cisco.com/news/cisco-integrated-system-for-microsoft-azure-stack - Cisco will not be that far behind.
They will use their UCS platform as the basis of their offering and more details can be found here - https://www.cisco.com/c/en/us/solutions/data-center/integrated-system-microsoft-azure-stack/index.html
Vijay Tewari, Group Manager for Azure Stack will be present at Cisco Live in Berlin (February 20-24) to discuss in more detail the work that has been undertaken by both companies.
