For an arguably mature technology, Cloud is a topic that continues to grab headlines and mindshare. While the days of asking “should we or shouldn’t we use cloud?” have long gone, the question has moved on. It’s no longer about whether cloud should be implemented, it’s about how it should be implemented.
The cloud journey for companies continues to evolve. Once companies started to overcome issues around privacy and security, they started to make decisions about whether to use private cloud, hosted private cloud or public cloud. Today, most companies understand that the type of cloud is no longer an “either or” choice.
Most companies had already adopted a hybrid approach where they combined the use of public and private cloud. Increasingly today, companies want to combine that approach with a multi-cloud strategy with “multi” referring to the use of multiple public clouds.
Some argue that only by adopting a true multi-cloud strategy “done right” can companies leverage and harness the true benefits of cloud. A multi-cloud strategy enables companies to get the most competitive pricing, moving cloud services to where they are best priced. It facilitates workload agility and mobility, creating the ability to move applications between clouds for any reason.
Multi-cloud also offers the possibility of enhanced resilience with the potential of moving applications and data from one cloud to another in the event of service of infrastructure downtime. Multi-cloud can even improve network performance, placing geographically spread out consumers of cloud services closer to where the compute occurs and the data resides, leveraging proximity to improve user experience.
Achieving “true” multi-cloud is easier said than done, and companies increasingly realise that having an on-premise hub that integrates with your hybrid and public cloud strategy is a critical component in being able to successfully implement a multi-cloud strategy. To do this, companies need an infrastructure that is not only built like a cloud but also uses the same building blocks of public cloud.
Hyperconverged infrastructure is essentially the technology that has made the hyperscale public clouds possible. Converging the three components of the data centre in easy to manage, easy to scale “appliances” has essentially created the building blocks which enable flexibility, scalability and manageability at hyperscale.
It makes sense then that a multi-cloud strategy should be underpinned with a hybrid architecture built with HCI technology that allows your on-premise cloud to integrate and interoperate with whichever public clouds you choose to consume.
When it comes to HCI, Dell EMC and Intel have been pioneering the technology since it first came to market. VxRail and VxFlex are the worlds leading HCI solutions, offering VMware focused and multi-hypervisor solutions. Recent innovations by Dell Technologies show how these HCI solutions are becoming the building block to unlock multi-cloud strategy. We see this manifest with solutions such as Dell EMC Cloud for Microsoft Azure Stack and also with VMware itself now running on most of the world’s major public clouds.
Companies can now make an investment in HCI which will form the fundamental building block of their ongoing multi-cloud strategy. They retain on-premise capability when they need it, but with the same manageability, they get with public cloud and an ever-converging ability to use one interface such as vCloud Director to manage workloads, applications and infrastructure across their on-premise and public cloud estates.
