From natural disasters to minor disruptions, every network is vulnerable to risk. While most business continuity and IT disaster recovery plans focus on protecting the data center, your plans should also ensure server availability and access to the business-critical apps, data, and collaboration tools that keep the business running. Remote access and WAN technologies are key, allowing people to work as usual, even during a natural emergency.
Citrix networking solutions work together to form a complete business continuity and IT disaster recovery plan. They ensure service and resource availability, a seamless user experience, undisrupted remote and branch access, and data replication.
In the event of a data center failure, NetScaler ADC automatically redirects user traffic to a secondary site, with no interruptions for users. Load balancing and global server load balancing across several data centers further ensures optimum server health, capacities, and utilization. And NetScaler SD-WAN provides a similar function for the WAN, automatically redirecting traffic across any available connections. In fact, the experience is so seamless, users won’t even realize any change has occurred. Their primary access IP address will remain unchanged, allowing users to access their apps and data using the same methods and devices.
During a business continuity event, data and apps are delivered to users in the same way they’re accustomed to—whether it’s LAN, WAN, broadband, satellite, hotspot, or mobile—with the same inherent security, control, compliance monitoring, and tracking.
NetScaler SD-WAN appliances continuously monitor every MPLS and broadband connection by tagging packets with sequence numbers. Destination appliances can detect path outages after just two or three missing packets, allowing seamless sub-second failover of traffic to the next-best WAN path. Users are never forced to restart, reconnect, or log in to applications again. Appliances also detect immediately when connections come back online, and seamlessly return traffic to the restored paths. Competing solutions can’t match this level of failover performance.
Technology is only one part of a comprehensive business continuity and IT disaster recovery strategy. Best practices also recommend defining a team structure; establishing recovery plans for specific event types; testing your plan; and creating a crisis communications strategy as well as employee safety and awareness programs.
