Some BOM’ing of Azure Stack:
Azure Stack is made of two basic components, the underlying infrastructure that customers purchase from one of Microsoft’s certified partners (initially Dell EMC, HPE and Lenovo) and software that is licensed from Microsoft.The software includes basic IaaS functions that make up a cloud, such as virtual machines, storage and virtual networking. Azure Stack includes some platform-as-a-service (PaaS) application-development features including the Azure Container Service and Microsoft’s Azure Functions serverless computing software, plus MySQL and SQL Server support. It comes with Azure Active Directory for user authentication.Customers also have access to a wide range of third-party apps from the Azure Marketplace, including OS images from companies like Red Hat and SuSE, and templates that can be installed to run programs like Cloud Foundry, Kubernetes and Mesosphere.On the hardware side, Azure Stack runs on a hyperconverged infrastructure stack that Microsoft and its hardware vendors have certified. The smallest production-level Azure Stack deployment is a four-server rack with three physical switches and a lifecycle management server host. Individual racks can scale up to 12 servers, and eventually, multiple racks can be scaled together. Dell EMC, HPE and Lenovo are initial launch partners. Cisco plans to offer a certified Azure Stack platform based on its UCS hardware line by the end of 2017 and Huawei will roll out Azure Stack support by the end of 2018.IDC Data Center Networking Research Analyst Brad Casemore says he believes customers will need to run at least a 10 Gigabit Ethernet cabling with dual-port mixing. Converged network interface cards, support for BGP and data center bridging are important too. Microsoft estimates that a full-sized, 12-rack server unit of Azure Stack can supply about 400 virtual machines with 2 CPUs and 7 GB of RAM, with resiliency.
And Lydia explains the “people want private cloud ¯_(ツ)_/¯” angle:
“This is definitely a plus in the Microsoft portfolio,” says Gartner VP and Distinguished Analyst Lydia Leong, but she says it’s not right for every customer. “I don’t think this is a fundamental game-changer in the dynamics of the IaaS market,” she notes, but “this is going to be another thing to compel Microsoft-centric organizations to use Azure.”
Leong expects this could be beneficial for customers who want to use Azure but some reason such as regulations, data sensitivity, or location of data prevents them from using the public cloud. If a customer has sensitive data they’re not willing to put in the public cloud, they could deploy Azure Stack behind their firewall to process data, then relatively easily interact with applications and data in the public cloud.
