            •       service operation centre: The management of processes and functions of data centres should be
                    controlled  by  a  dedicated  service  operation  centre,  which  will  mainly  take  in  charge  the
                    management  of  access,  events,  requests,  incidents,  service  desk  24x7,  technical  components,
                    applications and IT operations.

            As adoption increases, cloud services will continue to drive the evolution of several aspects of data centres
            in developing countries, from architecture to software and control processes.

            8.3.1   Data centres – Case studies


            Case study 1: National data Centres in Zambia
            Zambia  has  established  a  government  owned  cloud  service  provider,  the  Zambia  National  Data  Centre
            Limited (ZNDC). This is a company limited by guarantee through the ICT regulator, Zambia Information and
            Communications Technology Authority (ZICTA). The establishment of the ZNDC with three geo-located data
            centres will provide a platform for both government and private sector to consume secure, highly reliable
            and available cloud Services from the Tier III Uptime certified data centre.
            The data centres are not just traditional data centres offering reliable power and cooling services only. They
            are modular  data  centres built  on  cloud  architecture  with virtualization  as  the  bedrock.  The  three  data
            centres provide on demand cloud services such as e-mail as a service, infrastructure as a service (IaaS), back-
            up as a service (BaaS), disaster recovery as a service (DraaS) and platform as a service (PaaS).

            The high level topology of the data centres is shown in Figure 8-1:

            The national data centre has three sites that are located in geographically spread areas with a combined floor
            space of 1,600 square metres. The sites were chosen based on the country spread so that one site in the
            northern part of the country can serve the northern region of the country while the other two will serve the
            central and southern part of the country.

            The data centres are designed for an average power usage effectiveness (PUE) of 1.3. The facility has a
            combined rack count of 206 with 24/7 network operation centre technicians and mechanical and electrical
            (M&E) staff.
