Traditional infrastructures are too complex, too difficult to manage, too slow to adapt to changes, and too expensive to adequately respond to changing business needs. IT departments everywhere are looking to save money while becoming more efficient in terms of both resource provisioning and reaction time. Moreover, recent global events have accelerated many digital transformation initiatives and enterprises now need, more than ever, an IT infrastructure that can adequately support legacy and modern applications simultaneously while providing a consistent user experience across different on-premises and cloud environments.
A cloud-only IT strategy is not viable for many organizations. Even the most aggressive cloud-only strategies are now refocusing on a more balanced hybrid and multi-cloud approach. Unfortunately, mixing cloud and traditional IT infrastructures heightens the risk of creating silos, heading in exactly the wrong direction and complicating the overall infrastructure even more. Unlike traditional infrastructure patterns, however, hyperconverged infrastructure (HCI) is a step forward in simplicity and flexibility. HCI lets organizations hide IT infrastructure complexity while realizing the benefits of a cloud-like environment. HCI simplifies operations and makes the transport of data and applications between on-premises and cloud easier.
Initially, HCI was chosen mostly by small- and medium-sized enterprises as an alternative to traditional virtualized infrastructures for its simplicity and very limited set of workloads, like VDI. It is now common in larger organizations as well and covers a broad range of workloads, including all types of virtualized workloads, big data analytics, edge computing use cases, and more. In fact, for the most advanced solutions, the trade-offs between efficiency and simplicity are becoming less relevant, mostly thanks to the adoption of all-flash storage, and their feature sets allow them to address a wide range of applications now (see Figure 1). In some circumstances, HCI users can further optimize infrastructure by changing its purpose over time. For example, an HCI-based VDI can be quickly repurposed overnight for big data analytics or AI workloads that can take advantage of GPUs installed in the cluster nodes.
Though choosing the right HCI infrastructure remains challenging, the core technology is consolidated and most of the vendors have mature stacks. As we will see, what really makes the difference now are services and features built on top of this stack.
