It is not just the public cloud today, but it is Hybrid Cloud.
Microsoft is working on making our hybrid life less difficult by introducing Azure stack. We all know the pain of getting Microsoft System Center integrated and working on-premises to enable private cloud. Yes, I agree with you SC is not a candidate for comparing it with Azure Stack. However, I believe Azure Stack will be solving these issues and bringing cloud to your data center with ‘Pay as You Use’ Pricing model.
What is Azure stack as per Microsoft?
Microsoft Azure Stack is a hybrid cloud platform that lets you deliver Azure services from your organization’s datacenter. Bring the agility and fast-paced innovation of cloud computing to your on-premises environment with Azure Stack. This extension of Azure allows you to modernize your applications across hybrid cloud environments, balancing flexibility and control. Plus, developers can build applications using a consistent set of Azure services and DevOps processes and tools, then collaborate with operations to deploy to the location that best meets your business, technical and regulatory requirements.
