As you know back in September 2012, Microsoft launched Windows Server 2012. This brought an incredible number of new and an enhanced Hyper-V Capabilities. One year later in October 18th, 2013 Microsoft released Windows Server 2012 R2, which brought new capabilities ranged from enhancements around scalability, new storage and networking features, significant enhancements to the Live Migration capabilities, deeper integration with hardware, and an in-box VM replication capability, to name but a few. These improvements, new features and enhancements can be grouped into 4 key areas:
Scalability, Performance & Density – customers are looking to run bigger, more powerful virtual machines, to handle the demands of their biggest workloads. In addition, as hardware scale grows, customers wish to take advantage of the largest physical systems to drive the highest levels of density, and reduce overall costs.
Security & Multitenancy – Virtualized data centers are becoming more popular and practical every day. IT organizations and hosting providers have begun offering infrastructure as a service (IaaS), which provides more flexible, virtualized infrastructures to customers—“server instances on‑demand.” Because of this trend, IT organizations and hosting providers must offer customers enhanced security and isolation from one another, and in some cases, encrypted to meet compliance demands.
Flexible Infrastructure – In a modern datacenter, customers are looking to be agile, in order to respond to changing business demands quickly, and efficiently. Being able to move workloads flexibly around the infrastructure is of incredible importance, and in addition, customers want to be able to choose where best to deploy their workloads based on the needs of that workload specifically.
High Availability & Resiliency – As customers’ confidence in virtualization grows, and they virtualize their more mission-critical workloads, the importance of keeping those workloads continuously available grows significantly. Having capabilities built into the platform that not only help keep those workloads highly available, but also, in the event of a disaster, quick to restore in another geographical location, is of immense importance when choosing a platform for today’s modern datacenter.
To go deep through these 4 areas and to explore the challenges that customers are facing, and how the capabilities found within Windows Server 2012 R2 can help address those challenges with powerful, yet cost effective solutions are discussed in details in below technical white paper:
