As data processing requirements of individual client systems A to K change over time, they are allocated service from physical datacentres X, Y, Z according to the existing capabilities of the data centres requirements of the client systems, thus transferring client systems between cells controlled by individual data centres. This avoids the complex process of adapting the individual physical datacentres' capabilities to the changing requirements of the client systems to which they were originally allocated: thus the capabilities, and not the mappings, are maintained and the mappings, not the capabilities, are dynamic, so as to optimise the allocation of client systems to cells. It also minimises the number of clients having to work to more than one datacentre, which leads to delays in processing as the datacentres need to communicate with each other.Configuration of the datacentres X, Y, Z themselves is required to set up the system, but subsequently only if a re-optimization of the existing mappings cannot satisfy the changed demand profiles, for example because the overall balance of services available from the datacentres no longer matches the services required.

Databases that reside on a private network behind a firewall may be difficult to access from a cloud platform on the Internet. Techniques disclosed herein allow an Internet system to communicate with multiple different databases behind multiple different firewalls, however. A client-side private computer system, from behind a firewall, transmits a series of database request status inquires to a server system (not behind the firewall). These status inquiries may be sent as HTTP long poll messages. When the server wishes to query a database on the private network, it responds to one of the database request status inquiries. Because the client-side computer initiated communication, the server response is allowed to pass through the firewall when it might otherwise be blocked. Employing such techniques in parallel allows a server to interact with multiple firewalled databases without the difficulties and inconvenience of attempting a VPN connection.
