Complexity Creates Costs and Inhibits Innovation
While virtualisation as a technology simplified the running of server workloads some time ago, the complexity of the underlying infrastructure supporting the hypervisor has remained substantial. Leveraging discrete server, storage, backup and replication solutions does have its benefits for many enterprises. Particularly those organisations with low latency application requirements. However this complexity comes at a cost. Both direct and indirect. To compete in todays environment companies must remain agile and continually innovate. Yet such complexity often stifles agility as infrastructure delivery becomes cumbersome and time consuming. Innovation is restricted as an unfortunate result.
The advent of hyperconvergence and the single ‘superbox’ solution has made CIO’s rethink their long term infrastructure strategies. According to Gartner, Hyperconverged Integrated Systems (HCIS) will comprise infrastructures in 25% of all large enterprises by the year 2018.
An evolution of converged infrastructure systems. Hyperconvergence combines the hypervisor, compute, storage, network switching, backup, replication and real-time deduplication into a single box solution. Many also include ancillary services like cloud gateways, caching and WAN optimization - minimising the need for additional software common across enterprises. The hyperconvergence proposition for companies is extremely logical. Replace your disparate infrastructure components from multiple vendors with a single unit ‘turnkey’ solution. One which is fully integrated, commoditised and preconfigured with the hypervisor of your choice.
Enterprise scale is achieved simply by adding enough hyperconverged units to support the requirements of the desired virtual workloads. Complexity is reduced, agility is increased and performance and stability are maintained. At least that’s the theoretical concept at hand.
Public cloud architectures have gained significant attention in recent years. However hyperconvergence is quickly becoming a viable alternative for those seeking the on-demand scalability of a public cloud. Without the tradeoffs associated with moving systems and data offsite. For those looking to replace their traditional, physical desktop estates with a Virtual Desktop Infrastructure (VDI) solution, hyperconvergence also represents a potential high workload density option. Fitting more VDI’s on less hardware than the everpresent blade/san storage option found throught most enterprise data centres these days.
