Load balancing – Why important?
Load balancing is a common process popular with many organizations these days. It is a good way to distribute data among several servers so that overloading would not occur, as that can be detrimental to the working processes of apps and websites in an organization. Tech teams know how important it is to usher in severance and robustness in their organization. Basically, it is a good idea if your company makes use of many computers that run on the internet, and you need to serve all of them with your own servers. However, some individuals have also found it helpful to maintain load balancing on the network they use. If you’re wondering whether load balancing is for you, and you need to check what options are available to you, consider the following.

5. SeeSaw
SeeSaw is a product of Google. In 2016, Google made it an open-source technology. It is a Linux-based load balancing system. Today, the code of the project, written in Go language is now available on GitHub under the Apache license. SeeSaw allows clients to increase service availability and reduce management overhead. This load balancer is no longer an official Google product today because it is full an open-source project. In a nutshell, this product provides basic load balancing for servers that are on the same network. It also offers advanced load balancing functionality.
Features of SeeSaw
- Direct Server Return (DSR)
- Offers support for multiple VLANs and centralized configuration
- Designed to be reliable and easy to maintain
For it to work nicely, a SeeSaw v2 load balancing cluster needs two nodes that could be physical machines or virtual instances. Each node should have two network interfaces – one for the host, and the other for the cluster VIP. Because this load balancer is developed in the Go programming language, it is highly compatible with Ubuntu and supports DSR, two nodes, either physical or virtual.
6. HAproxy
HAproxy was created in 2013, and today, it is classed among the leading open-source load balancers out there. The company is based in Waltham, Massachusetts. It is another product that has huge patronage by companies like Instagram, Tumblr, GitHub, Reddit, and others.

The above are just a few of HAproxy load balancing features. Users could usually select server pools on request. If they want, a transparent proxy will allow users to connect to a server directly with a client IP address.
A further advantage of this load balancer is the security it offers to users. Over the years there have been very few vulnerabilities noticed by users. The balancer has a good culture of avoiding attacks even during start-up. Although the HAproxy can be used to monitor a client’s behavior over a period of time, it will block the client if suspicious moves are suspected by the load balancer.

Another option is the Round Robin which is one of the simplest methods for distributing client requests across a group of servers.

10. Gobetween
Gobetween is a bit different from the other load balancers mentioned above, in the sense that it is free for life open-source load balancer for the cloud era that many consider to be modern and minimalist in nature. It comes with layer 4 and a reverse proxy. This balancer works under multi-platforms OS, Linux, Windows, and Darwin. Although it exhibits fast performance, its performance trails those of the others mentioned above. It is also written in the Go programming language.

Its health checks are used to determine the service status of the backend nodes pool and if there is no health check server section defined, backend nodes marked as ‘ok’ can be deleted from the backend.
Conclusion
Your establishment needs load balancers because they help your systems from overloading and reduce response time from servers. Not having a load balancer means that you could be disappointed during peak periods when your servers are overloaded. Depending on what type of business you do, risking downtime during peak hours may be very costly.
To avoid loss, it is recommended that you consider a load balancer. Try one for free at first, then see if you could actually move to a premium edition. All companies that are seeking high availability have found that using a load balancer really helps.
