| Description |
Most companies are now utterly dependent on their information systems. Critical applications are essential to ongoing operations. What's more, many organizations now require the availability of their essential systems 4/7 to support Internet operations and/or global facilities, suppliers and customers. For these companies, downtime is not an option, regardless of the time of day or week. <p></p> Yet the need for system upgrades and migrations is inevitable. Growth in the business pushes the limits of existing systems. The demand for new functionality intensifies the strain. Even without pushing up against performance constraints, new hardware and operating systems that offer new highly productive or more secure functionality occasionally come along with the promise of an ROI that can't be ignored. <p></p> In the past, any upgrade or migration required system downtime--typically lots of downtime. This no longer has to be the case. HA solutions include inherent capabilities to facilitate migration and allow for parallel old and new operations until the new system is fully tested and ready to assume operations. Then, downtime is limited to the time required to switch users from the old system to the new--a task that the HA software can also help you to perform very quickly. <p></p> Even if you don't yet have an HA solution, software that includes some of the core HA functionality, such as Vision Solutions' Upgrade/Migrate While Active, can help you to accomplish the same objective of minimizing downtime, without the expense of implementing a full HA solution. |
