Operational Continuity

Esker offers several technologies to make sure your business is always online. Esker solutions are designed for dependable data processing easily scalable to meet the changing needs of any organisation with features such as load balancing, Microsoft® clustering support and Fax and Mail on Demand. And with 24/7 technical support, worldwide service and continuous availability, you can rest assured that your organisation will always be in good hands with Esker.


Load balancing

Load balancing improves processing efficiency by distributing workloads among servers. When loads are balanced, no single server can overload. For example, when sending and receiving faxes, load balancing improves overall conversion speed and fax transmission rate to ensure that the highest priority faxes transmit first. Load balancing balances loads for any multiserver system — single site or globally dispersed.

Microsoft clustering

By organising two or more servers to work together as one, Esker provides higher availability, reliability and scalability than can be obtained by using a single system.

  • High availability with continual access to critical delivery services while greatly reducing unscheduled outages. Esker meets scheduled uptime goals while reducing unplanned downtime and maximising total hours of service operation.
  • High reliability to reduce the frequency of system failure, while providing fault tolerance in case of failure. This minimises the number of single points of failure and reduces the risk that a single component/system failure will result in the outage of the entire delivery service.
  • High scalability as delivery needs change and grow. Esker solutions can be scaled to increase throughput capacity and performance by adding servers to clustered server farms.

Within a Microsoft cluster, the various servers — or nodes — are joined together so they appear as a single environment (a virtual server). Clustering Esker servers ensures that if one node fails, operations can be automatically assumed by another node in the cluster. This reduces unplanned downtime, improves total hours of service operation, and provides fault tolerance.

Continuous system monitoring (WatchDog)

Esker provides pro-active diagnostic tools looking out for any malfunction in the system. These tools are consolidated within a unique module called Esker WatchDog, which actively monitors the system 24/7 to ensure that your Esker server stays up and running. Esker WatchDog is always on alert, verifying that your Esker server is up and running. 

If any service fails, or any application freezes, the WatchDog will detect the error, reset the appropriate component and notify you if the problem cannot be resolved automatically.

The WatchDog will ensure minimal downtime and user inconveniences as well as prevent any loss within your business document processing.

Failover to on-demand

Mail and Fax on-demand give your company an extra layer of protection in times of unplanned maintenance or outage. Esker solutions offer an automatic and transparent failover to Fax or Mail on-demand services when local infrastructures are not responding, ensuring operational continuity.
