So everyone’s harping on about cloud disaster recovery and how it offers flexibility and scalability whilst being a cost beneficial way of protecting your IT systems from downtime. However, large enterprises are still largely carrying out disaster recovery in-house so what drives these decisions and what are the benefits of keeping your DR in-house?
1. Data Control. With Cybercrime rising by 48% in Europe from 2013 to 2014, financial losses are at stake if organisations don’t remain vigilant and agile. By retaining all data in-house within your control, and avoiding the use of a cloud, issues like security and compliance can be managed to a company’s requirements, and compliance and risk teams can be more easily appeased. Ultimately it’s about obtaining the resilience your stakeholders require which often means building a solution that meets your specific requirements is advantageous and gets the solution in place faster.
2. Bespoke tailoring. If you manage your disaster recovery in-house it is within your control to have flexible RTO and RPO objectives and build the correct solutions to meet the needs of your business. Increasingly organisations have RTO’s between 0 minutes and a few days, depending on the criticality of your system. Whilst cloud providers are now starting to be able to offer a mix and match approach, this normally comes with contractual tie-ins and an in-house approach gives you the ability to change your requirements with little notice as the business develops.
3. Performance. Match your resources properly, and you will have the optimal disaster recovery solution for your business. With instant failover for all your critical services and zero data loss, you can feel comfortable that your business won’t miss a keystroke or transaction and customers will never know you’ve experienced an issue with your live system.
4. Speed of scale. When new servers are being added, provided the hardware is not at capacity, new applications can be added to the disaster recovery site instantly. This means disaster recovery protection can be a simple and quick solution, with additional cost being minimal.
It can take a while for enterprises to adopt new approaches, not least because of the investment that has already been made in hardware. Adding to an in-house solution that has already been invested in, and that enables optimal performance is an obvious choice. It is only when cloud disaster recovery can bring advantages both in performance and cost that a business will choose to adopt this strategy. Of course, some enterprises are starting to take an approach of private cloud disaster recovery which may be the first step to handing over control to external suppliers.
