Intelligent, Cost Effective,
Cache-Accelerated HA Clusters

Domain-name aware, cache-intelligent load balancing.

Cross-datacenter high-availability replication and failover.

Load Balancing and Replication

  • tranditional load balancer diagram

    Traditional Load Balancers

    • Employ multiple disjointed hardware and software platforms
    • Require separate configuration and management routines for each platforms
    • Are hardware solutions that require physical space
    • Lack domain-name awareness and cache-replication friendliness
    • Involve multiple layers (protocol offloader, caching reverse proxy) between load balancer and backend server
  • litespeed web adc intelligent load balancer

    LiteSpeed Web ADC

    • Is a single cloud-deployable software-only solution
    • Is easily managed through a single WebAdmin interface
    • May be deployed virtually in the cloud
    • Provides layer 7 domain-name-aware intelligent balancing and cache-aware replication
    • Communicates directly with the backend server and eliminates overhead

Main Features

  • Cutting Edge Technologies

    At the heart of LiteSpeed Web ADC is our Edge Side Caching capability, providing both public and private (per user) flexible cache mechanisms that allow entire (cached) page assembly without backend access. Further enhanced by our HTTP/2 and QUIC functionality, and our SSL/TLS offloading capability, the flexible load balancing algorithm provides optimal performance and is configurable to match virtually every deployment.
  • Advanced Security

    For enhanced security environments, LiteSpeed Web ADC is able to securely communicate with HTTPS backends, as well as to drop to faster HTTP connectivity when Edge Side encryption is sufficient. LiteSpeed Web ADC provides Web Application Firewall Protection (compatible with mod_security), with Layer-7 Anti-DDoS Filtering as well as IP level bandwidth and request rate throttling.
  • Replication

    LiteSpeed Web ADC provides out-of-the box, real-time, asynchronous replication capability supporting deployment of High Availability servers even across data centers.
    Replicating cached objects synchronizes web cache content, reducing cache misses in case of ADC failover. Load balancing session information replication ensures the same backend server mapping across ADC instances, and SSL session/ticket replication enables SSL session resumption via any LiteSpeed Web ADC instance.
  • Best-of-Breed Solutions

    High Scalability, High Availability IP failover, Cross Datacenter Replication, Cache Data Synchronization and out-of-the box acceleration for Magento, Wordpress and other popular packages round out the feature set to make LiteSpeed Web ADC the best-of-breed solution on the market.
  • Simple Management

    The LiteSpeed Web ADC WebAdmin console provides a simple interface for managing configuration, restarting the server, monitoring cluster statistics, and managing High Availability features such as IP fail-over and replication.
  • Cost Efficient

    Our deploy-anywhere, software-only HA solution is dramatically more affordable than traditional deployments, and can be instantly migrated and scaled on demand.

Cluster Management Simplified

Our ZeroConf API makes HA clustering accessible for shared hosts. No longer must configuration changes be manually copied to the ADC. Each time a new site is created or removed, SSL is added, or an account is transferred from one box to another, ZeroConf client forwards the updated configuration to the front end node(s). ZeroConf addresses a shared hosting pain point and reduces complexity in an ever-changing environment.

Elaborate clusters with hundreds of sites can be a challenge to manage, but with ZeroConf, you can add and remove entire servers, mix-and-match cloud platforms, and manage DNS with ease. Sites that suffer from unpredictable traffic bursts can start up backend nodes on the fly, and let ZeroConf send the new configuration to the ADC node for immediate use.

ZeroConf simplifies the tedious aspects of cluster management and frees you to spend time on more interesting things.
