Protect Your Users' Experiences & Site Performance

Memcached produces dramatic increases in web site performance, so it has quickly become mission-critical to operators of most large web sites. Even the temporary loss of Memcached services can cause serious disruption to users, not to mention lingering performance impacts as new cache resources are brought online and are loaded with cache data. Gear6 Web Cache introduces a number of technologies to address these issues:

• Continuous service availability is provided by a clustered architecture with fail-over capabilities, so that cache services are not interrupted when failures occur. In typical Memcached deployments, the failure of a cache hardware module often causes its IP address to vanish, and a ripple effect of delays and failures can easily occur. By distributing cache services across multiple modules with fail-over, Gear6 Web Cache eliminates this problem.
• Continuous data availability is provided for cases where cache data rebuild time might be unacceptably long. Gear6 Web Cache data replication ensures that all cache data is always available in an alternate location, and continues to be served to users without interruption or delay. Spikes in database and application load are avoided.
• No client-side code modifications enables fast deployment. If you use Memcached today, you’re ready for Gear6 Web Cache. Because it is 100% Memcached protocol-compliant, the calls you already make to Memcached will seamlessly provide the density, high availability and the other benefits of Gear6 Web Cache.
• Disruption-free software upgrades are easy with Gear6 Web Cache. Software upgrades are easily scheduled, initiated, tracked and completed without taking down cache resources.
