Build a Redundant Infrastructure for High Availability
Equalizer offers multiple levels of redundancy to guarantee the highest levels of availability. Equalizer ensures service availability by supporting redundant application servers and server clusters, automatically detecting and compensating for any server or service failures. Additionally, redundant Equalizers may be deployed to eliminate any single point of failure. Finally, Geographic Server Load Balancing can be enabled to provide redundancy across multiple locations.
Equalizer Delivers:
- Multilevel Guarantee of Application Availability
- Ensures Seamless Disaster Recovery
- Deliver Traffic by Server Availability, Performance and Network Latency
Availability Begins with Reliability
The Coyote Point Equalizer is an appliance purpose built for reliable, high performance load balancing and application delivery. The appliance model has proven again and again to provide the most cost effective and reliable solutions by eliminating much of the administrative overhead associated with building and maintaining systems. Because our appliances are hardware devices designed for a specific task, site administrators can avoid the pitfalls and complication of building platform and OS dependent software based load balancing solutions. Equalizer makes it easy to implement a traffic management strategy that will deliver the highest level of application availability regardless of the application, operating system or protocol.
Multilevel High Availability and Redundancy
Level one: Scalability and application performance is meaningless if your servers aren't available. By going beyond the ability to distribute load across servers in a cluster and automatically monitor application and server health we can intelligently route around failures. We also monitor server load and application response times and route traffic to the fastest responding server available in the cluster. In this way if a server becomes unavailable or responds slowly due to load, end user access and productivity are unaffected because traffic is rerouting seamlessly to the best available server to meet the needs of the end user.
Level two: To guarantee even higher levels of availability the Equalizer appliance can be configured in a fault tolerant configuration with a redundant Equalizer appliance as a backup in hot standby. This allows network administrators to deliver maximum performance for any mission-critical application or service that requires 100% availability and ensures users are never impacted by unavailable network resources including individual server outages, application failures or even the loss of the Equalizer itself.
Level three: Geographic Server Load Balancing (GSLB) brings load balancing across all multiple data centers and completes the redundancy application delivery solution of the Equalizer. As any service or application is scaled, reliable performance is maintained only when you can route users to the server best equipped to process their requests. If there's a network outage, server failure or other disturbance, Envoy ensures availability by engaging surviving sites seamlessly. Geographic Query Protocol allows Equalizer to create fine-grained wide-area redirection for every client request without a drop of connection latency. Traffic is directed to multiple data centers according to business-defined policies matched against performance and availability metrics. Real-time performance and availability metrics are gathered from each data center to choose the best destination for each new request to ensure the highest levels of availability.
Business Continuity for Planned and Unplanned Outages
Outages are inevitable whether they are scheduled or not. In the case of a server or applications outage, Equalizer eliminates the necessity for IT staff to be on hand to replace one server with another working server or scramble to reroute traffic to another site. Whether you are there or not traffic reroutes automatically without administrator intervention. Individual servers can be taken in an out of the clusters without impacting application availability to the user population.
Coyote Point ensures business continuity on the micro and macro level. Equalizer is always vigilant, automatically monitoring application and server health locally or globally to assure network resources are available to serve the user community. Equalizer appliances automatically monitor application and server health along with server load and application response times. Equalizer then uses "application-aware" load balancing to route traffic more intelligently. Even if a server becomes unavailable, an application stops responding, or responds slowly due to load, end user access and application availability are uncompromised because traffic is rerouting seamlessly to the best available server. For business continuity "best" is defined as an available server with the appropriate content delivering the fastest response time.
Predictable, Reliable and Consistent
Multilevel reliability and redundancy mean administrators can breathe easier and users can count on service availability. The result is end users experience "always-on" application availability and administrators no longer need to schedule maintenance and upgrades after hours. Finally, no more maintenance schedules on weekends, and no more calls at midnight from frustrated users.
The bottom line for any business is making sure services offered are predictable, reliable and consistent. To offer that level of quality means having an infrastructure that promises the same. Equalizer offers intelligent application-aware load balancing, redundant configurations and Geographic Server Load Balancing for high availability and business continuity.
When you need reliability, scalability, and performance to deliver superior user experiences and the highest level of service continuity; Equalizer Delivers.
