Cloud is reliant on the data centre
Following the ITWEB Cloud & Virtualisation Conference held in Joburg in July, it was obvious to me that too little time is spent thinking about the back-end infrastructure when it comes to cloud. Cloud offers the virtual delivery of data centre components: virtual servers and storage and virtual networking. The decision to house your cloud services operation, or actual cloud within a data centre, should involve consideration of connectivity and down time, and the ability to match capacity with the requirement of the cloud.
In many respects, the concept of cloud and that of data centre colocation are alike in their cost-saving benefits to the organisation. Accessing business applications through the Internet reduces IT expenditure and resource costs in the same manner as outsourcing your data centre requirements. The cost of designing and building a data centre is one saving, but the benefits of vendor neutrality in a data centre and having access to numerous connections out of the environment is, in most cases, not possible for most in-house data centres.
Connectivity is the key
The key to cloud offerings is connectivity. Connectivity to international providers like Seacom and WACS, mobile operators; Cell C, Vodacom and MTN, terrestrial networks including Telkom and Broadband Infraco and fibre infrastructure provider, Dark Fibre Africa will ensure cloud providers can reach their clients and that the client, in turn, has choice. In a June 2012 article, the International Working Group on Cloud Computing Resiliency (IWGCR) was quoted saying that a total of 568 hours of downtime at 13 well-known cloud services since 2007 had an economic impact of more than USD71.7 million. Cloud reliability is not covered enough - and specifically not in reference to moving core applications into the cloud.
Outcomes from the ITWEB Cloud & Virtualisation Conference included the fact that cloud is now a mature technology. Reports stated that it is no longer about whether companies need cloud services or not, but rather about what to deploy into the cloud first. I would say that companies need first to ask who will provide the support and infrastructure behind your cloud or cloud services, and what is the connectivity available to such infrastructure to ensure limited down time?
