Dedicated Server Cluster Solutions

Load balanced or clustered servers are servers which share the load for incoming web service requests. We chose LiteSpeed Load Balancer (LSLB) which is a high-performance, content-aware, session-aware HTTP application load balancer. It can forward requests based on request content as well as session stickiness preference. LiteSpeed Load Balancer can help scale your application beyond one server deployment, as well as improve the reliability of your service in case of hardware failures.

  • Gzip compression with backend HTTP Server
  • Automatic HTTP protocol upgrade/downgrade to maintain persistent connection with backend servers
  • Massive shared hosting: load balance to millions of websites
  • URL rewrite
  • SSL acceleration
  • Geotargeting support
  • IPv6 support
  • Anti-(D)DoS attacks capability
  • Request filtering (HTTP firewall), filter attacking requests based on request content
  • Chroot for enhanced security

Security

LiteSpeed load balancer is designed to be a secure load balancer. With chroot jail, IP level bandwidth throttling, connection accounting, strict HTTP request checking, and URL context filtering, DoS effects are minimized and backend cluster is properly fenced away from the HTTP request layer reducing vulnerability.

  • High performance Secure HTTP (HTTPS): supports SSLv2, SSLv3 and TLSv1
  • IP level throttling (Bandwidth and Request Rate)
  • Comprehensive IP level connection accounting
  • Hotlink protection
  • Strict HTTP request checking
  • External application firewall for dynamic content
  • Chroot whole server process

Reliability

  • Zero downtime maintanance (include reconfiguration, software upgrade)
  • Watch dog and Instant recovery maximizes up-time
  • Graceful shutdown, all requests in process will be completed.
  • Runs completely in the user space, OS reliability is not affected
