EDITOR’S QUESTION These data centres typically cater to customers with a core need for external network connectivity. BART VAN DER SLOOT, MANAGING DIRECTOR LEASEWEB NETWORK, LEASEWEB NETWORK GLOBAL eing a provider of hybrid cloud hosting services, open networking solutions that provide connectivity between Leaseweb and other cloud platforms are vitally important for us and our customers. B This is because a hybrid multi-cloud framework provides a business with the flexibility to move workloads between vendors and environments as required, as well as switch out cloud services and vendors for any reason. In our experience, the ability to offer this depends on five key criteria when either selecting or modernising a data centre: 1) availability and stability of power and temperature, 2) security (physical and logical), 3) flexibility (to grow – or shrink), 30 Issue 10 4) accessibility and operational support and 5) network connectivity. With regard to network connectivity, it’s important to differentiate between internal connectivity (this could concern different racks of one customer, or be between a customer and their partners or suppliers) and external connectivity, such as the presence of telecom carriers, network service providers or Internet exchanges to services like Internet access, (virtual) private networks, or public peering. Bearing this in mind, we see a wide variety in approaches to connectivity. At one end of the scale we see data centres that provide space and power, and for those customers who may want to, the ability to install their own cross connects between their racks, as well as to partners. At the other end of the spectrum, we also see data centres that aim to provide all interconnection services themselves – not only cross connects between racks, but also Internet exchange, Internet access or international private network services. The risk with selecting such a one- stop-shop is that it has the potential to drastically limit the flexibility to move elsewhere, as already explained. Additionally, once sufficient customers are present and interconnected, there’s a tendency to raise prices for interconnection services. It’s a trend we’ve observed in many data centres around the world, especially in the US and Asia Pacific where the number of data centre providers were initially very small. For example, whereas the price of a cross connect may be less than £20 per month in some European data centres, it can easily ramp up to over £300 per month in some US data centres. Therefore, when selecting a data centre, our advice would be to think carefully before putting all your ‘rack and connection’ eggs in one basket. Modern data centres that make provision for hybrid frameworks using open networking solutions are in the best position to support flexibility when it comes to both workloads and cost. www.intelligentdatacentres.com
