Security & Compliance have been long standing reasons for organizations to delay Cloud adoption. Companies are reluctant to host core business apps outside of their own datacentres. While email, file sharing and other collaborative functions find easy acceptance for Cloud storage, concerns around Cyber-attacks and Legal liability continue to hinder Cloud adoption.
Over the past few years however, cloud services have become a go to option for large and SME (small and medium size enterprise) companies that are looking to improve their businesses by employing IT solutions and services. The obvious advantage here is the scalability and accessibility to new applications, resources and services at a lower cost of ownership.
The Azure Stack helps bridge the gap with a hybrid model that help companies get the best out of Cloud computing, while still maintaining the integrity of their intellectual property. What this means is that with Azure it is possible to stage the implementation of company specific apps both On Premise as well as in the Public Cloud. Those apps that can be shifted to the public Azure cloud, can be easily moved from on Premise to the Azure Public Cloud. This delivers the ability to be in the same environment both on Premise and in the Public Cloud using internal datacentre environments for development and testing.
While the whole idea of Cloud is to offload workloads to a third party and to minimize the IT departments footprint, a hybrid model ensures risk mitigation for concerns around security and compliance.
Virtualization and Cloud
For most organizations, IT scalability has traditionally been linked to big investments in servers. Virtualization with offerings like VMware has greatly simplified scalability without immediate investment in hardware. However, for every new virtual machine, there are additional overheads for things like operating systems, core application etc.
What differentiates the Azure Stack from traditional virtualization is its ability to aggregate different IT components and provide the resources to run applications. While importing VMs is still possible for high availability scenarios, users also have the option of running Infrastructure as a Service (IaaS) with VMs as well as Platform as a Service (PaaS).
The Azure Stack enables rapid scalability to run several IT instances with a large capacity to host on the Public Cloud and at a much lower cost when compared to the large overheads associated with building several virtual machines.
