Private Cloud

Private Cloud

By definition private cloud is the infrastructure intended for usage by a single organization incorporating multiple customers (for example, departments of that organization), and possibly also by clients and contractors of that organization. Private cloud can be owned, maintained and operated by organization itself as well as by a third party (or a combination of those), while it can physically exist either within owner’s jurisdiction or outside of it.

Preconditions for setting up a private cloud

Some time ago, a platform could be in service for several years in a row, but under conditions of nowadays a system should by upgraded at least every year, which increases maintenance costs progressively.
Constant evolution of new technologies challenges every organization with certain difficulties. Small and medium business enterprises are not ready for continuous investments to IT infrastructure upgrading. Outsourcing is the only acceptable alternative under such conditions

Companies having IT departments with 10-20 year history do believe in the value of owning information systems and having full control over them. Companies, whose IT departments began forming a year or two ago, are not so conservative if the right to own turns out an expensive option. And the question is not about license costs. In order for an organization to host an information system, it should have a dedicated data center and the staff with corresponding qualification for its maintenance. Highly efficient and affordable system suitable for all relevant tasks of a business is not so easy to build. As soon as automation process will start within a company, IT department’s demands will be increasing in geometric progression, with all of them being important, absolutely necessary, justified, having a high ROI and also extremely high-priced.

What a company CEO should do in order to moderate the flow of IT demands?

The answer is not to build own data center.

This approach is quite usual for large businesses. Provided majority of offices are connected to data center not by local network connection but using some other means, why don’t move the data center to a professional operator? Professional operators provide environments where all technical requirements are met, emergency power supply organized, cold and hot corridors provided, a pair of reserve channels set up, security handled etc. Maintenance can also be delegated to third party organizations. As a result, practically all server hardware will operate outside of organization, while IT services, upgrades, adjustments and maintenance of both software and hardware components are carried out by outsourcing companies. Offices will house only workstations and a minimum staff of IT specialists responsible for tech support. But then again, tech support can well be outsourced, too.

If a concept of remote data center on provider’s territory is already acceptable, then it is time to take the next step – private cloud. Cloud services provide users with several collaboration models, when outsourcing depth is determined by the client himself according to assigned tasks.

- IaaS (Infrastructure as a Service) — both physical and virtual cloud infrastructures (networks, hardware, operating systems) are maintained by cloud service provider. At the same time, the customer is given an opportunity to install and run almost any kind of software including operating systems, platform software and applications.

- PaaS (Platform as a Service) — renting IT resources and operating system from provider. Customers get a flexible information encironment, which can be easily scaled according to tasks that need to be carried out.
- SaaS (Software as a Service) — is an opportunity to use any application without necessity to own a platform that runs the needed application. All updates, patches, hardware configuration changes are usually included to the subscription for chosen application.

Along with these types of of aaS, providers offer many other solutions: disk array as a service, business process as a service and so on. Absolutely every IT process can be outsourced. Today you don’t necessarily have to own an IT infrastructure in order to build an efficient IT environment.
