Achieving Enterprises Database Availability Goals
When enterprises move their applications and data to the cloud, they do it with the aim of saving money and massively increasing the agility of their IT and business systems. However, this comes with its own set of challenges that need to be overcome in order to adhere to the requirements of business-critical applications on the cloud. Many enterprise applications that are hosted on databases will go through periods of spikes in performance and these spikes can more often than not slow applications, or in some cases, bring down the whole network. Enterprises cannot deal with downtimes as they are far too expensive and much more of an inconvenience.
Enterprises can use high-availability strategies for their database environments. An end-to-end high-availability strategy includes architecture, platform governance, operational processes and technical solutions. After enterprises identify the requirements specific to their organizations, they can create the strategy. For it to be successful there has to be an optimal balance between business requirements, IT SLAs, IT support capabilities, technical solutions and infrastructure costs.
Today, the advances in virtualization technology enable enterprises to employ virtual machines whenever needed. These systems will provide the required functionality to enable databases to be Always On while also being flexible and cost-effective. That being said, it is paramount that the virtual machines must handle the capacity and the load of the physical machines they are meant to substitute/ replace.
