Best Open Source Load Balancers To Enhance Performance

There are essentially three different types of open source load balancers.

  • Hardware-base
  • Cloud-base
  • Software-base

A load balancer is a piece of hardware designed to distribute the load across multiple servers. Among the most recognizable brands of LB equipment are:

  • F5
  • TP-Link
  • Barracuda

While expensive, they give you complete freedom of expression.

Load balancers in the cloud are gaining popularity.

With cloud LB, you won’t need to invest in an expensive hardware appliance, saving you a ton of cash. You’ll pay exactly for the resources you consume. We’ve compiled a list of the most widely used cloud LBs.

  • AWS
  • By means of the Google Cloud Platform
  • Cloudflare
  • Incapsula
  • DigitalOcean
  • Azure

The minimum commitment is only $20 each month accordingly.

The third and last option is software-based and calls for individualized LB system installation, operation, and fine-tuning. It might be given out for free or sold to the highest bidder accordingly.

For those on a tight budget or simply interested in learning more about free load balancers, the information provided here is invaluable.

Best Open Source Load Balancers To Enhance Performance

1. Seesaw

To evenly disperse traffic inside the same network, Google uses a trusted virtual load balancer server running Linux.

Seesaw was developed using the Go programming language, and it is compatible with the Ubuntu/Debian distribution. Two Seesaw nodes are required for anycast and direct server return (DSR). There’s a chance they don’t exist anywhere but in cyberspace accordingly.

Those looking for layer seven load balancing will have to look elsewhere, as Seesaw is only compatible with layer four networks.

2. KEMP

KEMP’s powerful application delivery controller is compatible with all of the most common hypervisors, and the software is available for free. Use it on your own servers or upload it to a cloud service like AWS or Azure.

The following features are available to you at no extra charge, and they are all of commercial quality.

  • Using round robin or the least connection approach, Layer 4 TCP/UDP may balance traffic loads.
  • Layer 7 Stability at a Standstill
  • Integrate a Firewall for Websites (WAF)
  • Security from potential intruders within (IPS)
  • With the ability to host many sites and a truly global load balancing mechanism for servers,
  • Storage, compression, and re-routing of content
  • Cookies That Last Forever In Your Web Browser
  • Constructing an IPsec Tunnel
  • Pre-authentication
  • Let’s see if we can decode this.
  • Kubernetes

Many different kinds of businesses use KEMP LB, from Apple and Sony to JP Morgan to Audi and Hyundai. If you require additional functionality not included in the free edition, a paid business license is also available accordingly.

If you or your business are curious in KEMP LB and would benefit from a more in-depth, self-paced education, Mike Walton’s online course is an excellent option.

3.  HAProxy

open source load balancers

High availability, proxy support, and TCP/HTTP load balancing are often used and well-liked features. Here are a few high-profile companies that rely on HAProxy:

  • Airbnb
  • GitHub
  • Imgur
  • Reddit

The following are some key distinctions:

  • It supports UNIX sockets and IPv6.
  • It uses both a deflating method and a gzip compression method.
  • Health-check
  • Keeping sessions alive based on where they came from
  • Analysis and data acquisition in tandem (checkout demo)

Business, physical, and virtual appliance choices are all present and accounted for with HAProxy. It is one of the best open source load balancers accordingly.

Experiment on your own to get the hang of HAProxy. The Community Edition has several useful functions and is reasonably priced.

4. Zevenet

Layers 3, 4, and 7 are all within Zevenet’s capabilities, however Layer 2 is not. The source code, an IOS image, and a docker repository, are all available for download. It is one of the best open source load balancers accordingly.

It enables thorough monitoring of the system’s health, facilitating the fast removal of malfunctioning servers or services. Formerly known by its original name, “Zen,” Zevenet is backwards-compatible with various TCP protocols.

If you require a host for Zevenet, you may want to look into Kamatera.

5. Neutrino

open source load balancers

Neutrino is an eBay-develop system written in Scala and utilizing the Netty web server. It has the following switching properties and is backwards-compatible with least-connection and round-robin routing:

  • To Define Normative Terms
  • Context-base
  • TCP port numbers are use for L4-level communication.

Neutrino has been demonstrate in benchmarks to process over 300 requests per second on a 2-core virtual computer. Neutrino’s L7 switching is very impressive when compare to HAProxy.

Nonetheless, it’s wise to test out both options to discover which one works best for you.

6. Balance

Design in-house, Balance is a round-robin TCP proxy LB that works with IPv6. Certainly, IPv4 and IPv6 can coexist without any problems. It is one of the best open source load balancers accordingly.

This LB had all the hallmarks you’d expect to find in an LB.

7. Pen

Pen has been try on Linux, FreeBSD, HP-UX, Solaris, and Windows, so there’s no reason it wouldn’t work on any other Unix distribution. It is compatible with protocols like HTTP, SNMP, and DNS, which rely on the UDP and TCP transport layers.

In addition to the usual features, the following are some that are include at no extra cost.

  • Geolocation-base screening of incoming IP addresses
  • SSL’s Final Chapter
  • Compatible with IPv4 and IPv6

8. Nginx

I really get what you’re trying to say. Nginx is versatile, serving multiple purposes. Nginx, on the other hand, facilitates some elementary cross-server content switching and request routing.

But Nginx Plus is capable of much more. It is one of the best open source load balancers accordingly.

Nginx Plus is an online application delivery system that features load balancing, content caching, a web server, a web application firewall (WAF), monitoring, and more. It provides a practical alternative to more conventional load balancing methods, allowing applications to process millions of requests per second.

9.  Traefik

open source load balancers

A state-of-the-art, extremely quick, and entirely GO-written HTTP proxy backend. Connecting to several back-end services is possible with Traefik. Resources like the Amazon Elastic Container Service (ECS), Docker, Kubernetes, Rancher, etc.

Support for WebSockets, HTTP/2, and the automatic renewal of SSL certificates using Let’s Encrypt are just a few of the features, and the management and monitoring interface is slick to boot.

10. Gobetween

open source load balancers

The Layer 4 protocols TCP, TLS, and UDP e.g. are what make Gobetween the efficient and lightweight load balancer that it is. It is one of the best open source load balancers accordingly.

Its source code can be compile for use on a variety of platforms, including Windows, Linux, Docker, and Darwin. The balance is execute base on the algorithms that you pick in the configurations.

  • Calculating the hash of an IP address
  • Renown on a global scale, and featuring a round-robin structure
  • Reduce bandwidth to its bare essentials
  • Most likely to break down
  • Weight

When compare to HAProxy and Nginx, Go-between is noticeably slower.

Go-between seems like a decent bet if you require an advance L4 load-balancing solution with auto-discovery for a dynamic environment. Try it out and see if you like it.

Closure:

Basically in closing of the Best Open Source Load Balancers, I hope that the above data pertaining to open-source load balancer software has been helpful to you in reaching a conclusion. Since all of the possibilities are cost-free, you can safely experiment to find the one that suits you best.
