Business Continuity encompasses a variety of different concepts. At the simplest level, there may just be a requirement to meet unexpected peaks in demand for web based services – cloud bursting. There might even be a need to add and remove services as part of an application upgrade – while maintaining the ability to fall back to a previous known-good version if any problems arise. Another example might be the need to absorb and merge infrastructure and services should one company acquire another and need to present a single face to their customers. There is the worst-case scenario, where applications servers might become unavailable.
These in turn can form part of a broader strategy when planning for outages. There are many possible scenarios to consider, and many products and services available to provide disaster recovery. Scenarios can range from simple bursting to the cloud to maintain service levels, to policy-based traffic steering across AWS regions to a comprehensive active-active failover configuration.
KEMP’s Virtual LoadMaster provides some of these capabilities thanks to its built-in load balancing and High Availability (HA) features. It can also form a component of protected application workloads when deployed in conjunction with services protected by AWS Site Recovery.
