While serving requests over HTTPS, web server performance drops as much as 40% compared to its plain HTML performance. HTTPS delivery has a toll on web application performance because the same CPU has to perform SSL encryption besides web application delivery.
MettleHLD install module provides SSL offloading into Mettle SE relieving Web server just for running the web application. Hardware based encryption module in Mettle SE provides wire-speed delivery of the web application traffic. So HTTPS will no longer cause a latency in application delivery.
MettleHLD also enables centralized management of SSL certificates. One module can support multiple HTTP websites.
In addition to encryption offloading, MettleHLD also provides application server load balancing and automatic server failover.
