Load balancing ensures high system availability through the distribution of workload across multiple components. Compared to the single instance usage, such an approach ensures greater reliability through redundancy. Jelastic uses two types of load balancing: TCP and HTTP.
HTTP load balancing dominates in Jelastic. As a reverse proxy server for HTTP protocol the NGINX, Apache, HAProxy or Varnish load balancers can be used.
NGINX is the second-most popular open source web server in the world, which gives customers great performance and efficiency for their applications. Using NGINX requires no extra deployment steps or pre-configuration. NGINX offers built-in Layer 7 load balancing and content caching to provide a cost-effective and highly available platform for applications hosting. NGINX with its scalability, security and high efficiency in memory and CPU became the fastest web server in the world.
