24 DATA CENTRE OF TOMORROW close to the public cloud as possible; using public Internet connections to connect to public cloud can expose users to possible congestion and latency issues, while direct connections do not come cheap. This will lead to highly scalable data centres being able to host and connect all the required public, private and legacy infrastructures, using the various backup solutions available, for data stored in all environments. Apart from reducing costs and latency, it will ensure a far higher level of control for users. Bypass the Internet Data centres bypassing the Internet will become increasingly common practice. While it’s still relied on by many enterprises for their public cloud services, the major service providers have more recently developed secure, predictable access methods to support organisations. By using data centres equipped with cloud gateways, such as Next Generation Data, public, hybrid and legacy users can expect to achieve the same level of seamless experience as those using private cloud only. Data centres equipped with such cloud gateways will allow fast, highly secure private network connections directly into the global public cloud network infrastructures, such as Microsoft’s Azure ExpressRoute. By seamlessly connecting into these subsea cable and terrestrial networks and bypassing the public internet, users will increase security, reduce latency and optimise bandwidth in one fell swoop. Furthermore, with multiple interfaces, private connectivity to multiple cloud locations can be achieved and will ultimately improve resiliency. Cloud gateways will also allow the flexibility for users to separate their connectivity provider from the cloud provider, and therefore have greater control over costs than purchasing all aspects of the solution from a single provider. Beyond the Cloud Just like the cloud, Big Data, The IoT and HPC ultimately require physical elements to sustain them – scalable, powerful processing and storage, high-speed low latency connectivity, security, and abundant power. Older data centres housing IT systems typically doubling in performance every two years in accordance with Moore’s Law, will likely struggle to support the new unprecedented compute demands of our new highly data-intensive age. The way forward is to have a highly flexible infrastructure that can adapt and grow to deliver the increasing power, cooling and connectivity necessary. A typical rack in a data centre used to consume under 2kW of power, and older data centres were built to support this level. However, expecting customers to now use two, three, four or more times the space to support increased power requirements will not be acceptable practice. Ultimately, IoT fuelled Big Data, including that from driverless vehicles, will accelerate the demand for HPC – they’re inextricably linked. But the answer doesn’t have to mean a return to building expensive in-house data centres that will rapidly age and fail to keep pace with the power and cooling demands of such high density environments. Instead, we’ll see HPC-ready colocation data centres emerging with the space, power, cooling and connectivity necessary to support clusters of very high-density server racks. By choosing the right colocation provider, an organisation will be able to grow or shrink its HPC platform as required, with the knowledge that the facility provider will not be a constraint on their needs. This solution must not only offer a future-proofed data centre infrastructure to accommodate rapid expansion, but also provide the essential engineering skills necessary for the design and build of highly bespoke environments. Tomorrow’s data centres must have the flexibility and scalability to offer all of the essential components necessary for ensuring organisations of all shapes and sizes can meet immediate and future requirements. IT has never experienced such dramatic changes as we experience now, and will continue to do so. Flexibility, with the ability to change direction without the significant sunk costs in ‘build your own’ data centres is the way forward for enterprise customers. Physical security, vast space, and plentiful power are all prerequisites, but without fit for purpose and redundant network connectivity, the resilience, predictability and seamless experience users expect will be put at risk. n www.networkseuropemagazine.com
