IT needs are complex. No single solution will suffice. Different organizations demand and get different types of solutions to their needs. The scenario is not different with Cloud backup technologies. Organizations have a choice of implementing Private, Public or hybrid Clouds in accordance with their needs. The choice of the right type of Cloud will be made when the customer demands mature, and they understand the potential of the Cloud or learn to exploit its nuances.
Customers can determine the kind of Cloud that is best fit for their organization by addressing strategic questions that define the gap between available capacities and future direction of growth of their business. For instance, if the organizational data is highly confidential, as in the case of health records of patients or records of clients of a legal firm, the entity / customer should ideally opt for the deployment of a private Cloud. If certain types of data should be accessible to the customer and the data is not so confidential, the enterprise may choose to host the information in a public Cloud. If the organization would like to keep certain types of data confidential and share others with its stakeholders, it can choose to implement a hybrid Cloud. Cloud backup service providers may create specialty Clouds for a group of industries or the Government. Multi-national companies may build “internal Clouds” for maintaining a consistent quality of service to its stakeholders.
Not all applications and data types can be migrated to the Cloud. For instance, legacy data bases may not adapt easily to Cloud backup constructs. The original hardware / software configurations that were part of the legacy system may not integrate with the Internet driven, Cloud backup software. An entire redesign may be called for. As a result, the Cloud backup decision should be followed by a detailed and careful evaluation of all the applications that exist in the current system and whether these applications are in a state of “readiness to move”. If not, a massive redesign of the applications or a discard of the applications may be required to set up the Cloud backup system for the organization.
The selection of the ‘best fit’ will impact the way the organization is run, the way work is executed. Organizations will have to make a number of decisions on related issues such as the use of BYOD, mobile workforce policies, telecommuting policies, security policies and a host of other policies that suddenly become significant. These decision points were never considered major strategic business decisions in the world that did not know Cloud backup technology.
