These facilities are far enough from city centres for disaster recovery purposes, but close enough to deliver application performance that local and international businesses demand. Security ‘Top five things to consider when choosing a colocation partner: Location, security, connectivity, flexibility and Total Cost of Service.’ Security is one of the main reasons that some large organisations have traditionally preferred to build their own data centres. As this is often becoming financially unviable, providers must demonstrate that the security of their customers’ IT infrastructure is one of their highest priorities. Both external and internal security are paramount. Security requirements should be looked at in three key ways: 1. Physical: There should be at least seven layers of physical security that can be tailored for enhanced levels, as required. From perimeter fencing with intruder detection, access control, CCTV – external and internal – restricted pass code access, man and vehicle traps; data centres can guarantee the highest security needs that any industry sector needs. 2. Process: ISO27001:2013 certification should be in place to evidence processes and procedures and show that every aspect of security is tested regularly. 3. Digital: Easy access to a choice of DDoS mitigation services should be available through an ecosystem. Providers that partner with key digital security vendors create a strong defence so businesses can deal with attacks should they materialise. Connectivity Businesses use public clouds for access to huge amounts of data and massive compute capability, for on demand computing when needed, or simply for storage. But they still maintain their own private clouds as a way of processing and adding value to their own sensitive data that they collect and to handle complex computations. This is the hybrid world that is becoming the de facto standard. Connectivity to the right carriers is critical if cloud is to work. This ensures that multiple public clouds can be accessed, which will increase performance. The term for this is ‘on-ramp to cloud’. Companies should be aware that whilst some data centre providers can build the best high performance computing platform, without connectivity provisioning on-ramp to other clouds, businesses won’t be able to adopt a hybrid cloud strategy. Location Businesses today expect low- latency and reliability from colocation providers, with zero tolerance for downtime. However, the data centre does not have to be located in a city, it can be located on the outskirts which eliminates expensive city centre premiums. Smart providers chose optimal locations combining low cost availability of ample space and power for hyper efficient data centres with low cost availability of broad and rich connectivity (fibre that today’s digital businesses September 2017 | 29
