Load Balancing Out-of-the-Box

Get high availability with smart load distribution on infrastructure and application levels


Balancing on the Infrastructure Level

All of the incoming requests to the environments hosted within Jelastic PaaS are processed either by the platform Shared Load Balancer (SLB) or via Public IP (v4 and v6) address attached directly to the node.

The SLB is free of charge option, which is recommended for your dev and test environments. As for the production ones with the requirement of high traffic handling, it is more appropriate to use a Public IP for receiving and processing the requests.

Load Balancing on Application Levels


NGINX, one of the most popular open source servers in the world, which provides customers with great performance, ensuring the efficiency of the balancing. It offers scalability, security, high resource usage rentability, built-in Layer 7 load balancing and content caching for the cost-effective and highly available applications hosting


HAProxy (High Availability Proxy) is a fast and reliable open-source solution, which offers high availability, load balancing, DDoS mitigation, and proxying for applications. A single-process, event-driven model with low (and stable) memory consumption ensures smooth and cost-efficient load-balancing


Apache load balancer is an open source traffic distribution server, which provides high customizability through its modular structure. Apache balancer meets the unique requirements of each given environment and ensures such benefits as security, high availability, speed, reliability, and centralized authentication


Varnish is a web application accelerator also known as a caching HTTP reverse proxy for dynamic websites with high traffic. Within Jelastic, it is delivered in a bundle with the NGINX server, that lets work with the secured data and the Custom SSL option in particular


LiteSpeed Web ADC is high-performing HTTP load balancer application. Feature-rich, secure, and efficient, it offers more flexibility than similarly-priced load balancing software. Web ADC is an excellent choice for small enterprises looking to scale their applications beyond one server

Automated Traffic Distribution

Round Robin allows distributing requests one-by-one among the servers with preconfigured priorities and traffic ratio

Round Robin

Sticky Sessions assigns end users to a specific backend, which receives requests while the corresponding session is live

Sticky Sessions

Failover traffic routing allows redirecting the customers to a backup standby server in case of a production one failure


Perform blue-green deploy, A/B testing and failover protection using built-in add-on that provides
smart traffic routing between environments based on your requirements


Benefits of Load Balancing with Jelastic PaaS

Easy Start Easy Start

The traffic load balancing is a fairly simple process with Jelastic PaaS due to intuitive GUI and out-of-box automation for the most processes

Automatic Scaling Automatic Scaling

Load balancer instances are automatically scaled vertically based on the current load and can be scaled horizontally to provide redundancy

Traffic Management Tools Traffic Management Tools

Multiple built-in tools to help with the traffic management: traffic distributor, endpoints, container firewall, environment isolation, custom domains, etc

Efficiency and Fair Price Efficiency and Fair Price

The low RAM/CPU consumption footprint of the managed load balancers and platform pay-as-you-use pricing model ensure the low hosting cost

Managed Certified Stacks Managed Certified Stacks

Multiple load balancer stacks (NGINX, HAProxy, Varnish, and Apache) are maintained by Jelastic, ensuring the best optimization and regular updates

 Public IP and SSL Public IP and SSL

Traffic routing can be securely performed via Public IPv4 and IPv6 for production environments, as well as complemented with Let’s Encrypt or custom SSL certificate
