Viewed as a long-term IT insurance plan, disaster recovery has for years been a focal point for businesses. And, as more enterprise workloads move off-site, organizations are building a disaster recovery architecture with cloud and colocation to meet their specific needs.
But before getting started, evaluate the pros and cons of using cloud vs. colocation for disaster recovery, including geographic distance, business continuity options and overall costs.
Also, given the risks of outages and increased downtime that keeps IT out of the loop, it's important to plan and test your disaster recovery architecture -- whether using cloud, colocation or another model -- before a problem occurs. Learn from the mistakes of others and continuously improve your plan to meet the growing needs of the business.
1Colocation vs. cloud for DR-
Explore cloud and colocation for disaster recovery
Cloud and colocation offer IT teams different options when it comes to building a disaster recovery architecture. In general, both models provide organizations with a more efficient and cost-effective alternative to building another data center for recovery purposes. But there are differences to keep in mind. Weigh the pros and cons of cloud vs. colocation for disaster recovery (DR), ranging from financial and geographic differences, before deciding which option is right for your company.
Disaster recovery as a service (DRaaS) provides IT with a cheaper alternative to traditional DR, but cloud-based backup also poses new challenges, such as the potential for unavailability after a major disaster and the need for increased network bandwidth. Continue Reading
To make the right decision regarding IT business continuity, weigh the arguments for both colocation and cloud. For example, colocation might be more expensive in the long run, but in the cloud, you run the risk of a provider cutting corners. Continue Reading
Traditional methods for DR and IT continuity, such as using a mirrored data center, can quickly drive up costs. Evaluate tools to manage workload transfers, and incorporate cloud or virtualization, to make a more affordable IT service continuity plan for your business. Continue Reading
Server management and quick access to data are two benefits for businesses when shifting disaster recovery to cloud or managed colocation -- but there are distinct differences between the two. Examine both options to make the right call. Continue Reading
Hosted colocation and disaster recovery as a service provide data recovery options for IT. DR testing is different for DRaaS and colocation. Know these differences before signing up. Continue Reading
Before enlisting a colocation provider for disaster recovery, ask questions about availability, accessibility, stability and location to determine if it's the right choice for your business. Continue Reading
Manage disaster recovery policies and costs
Whether you use cloud or colocation for your disaster recovery architecture -- or even a secondary data center -- it's crucial to carefully review and manage DR policies, and to keep DR costs in check. Can costs be reduced with other measures, such as streamlined testing? What are your organization's recovery time objectives and recovery point objectives? Investigate where your DR strategy is working, and which areas can be boosted to create a safer plan in the event of a disaster.
A serious data center emergency, such as a fire, proves how crucial disaster recovery policies are to an organization. To prepare for any nightmare scenario, examine the DR policies your company has in place, including the plan to transfer operations to a backup DR site. Continue Reading
Following a data center disaster, a DR report outlining key failure points can help avoid major problems in the future. Here are six issues discovered, ranging from poor facility design to faulty cooling systems, in one real-world example. Continue Reading
To restart applications as quickly as possible after a node fails in the data center, consider automating a failover system. Eliminate manual intervention and implement automation scripts to accelerate the restart process. Continue Reading
