What is Load Balancing Software? 

Load Balancing Software is an application delivery infrastructure designed to distribute network traffic among multiple servers to optimize the platform's performance. The software acts as a low-latency traffic processor. It can help with application availability, scalability, security performance, etc., and prevent failure.

Types of Load Balancing Algorithms:

Round Robin: Round robin algorithm sequentially distributes incoming traffic requests rotationally through DNS. It is considered as one of the commonly used algorithms in the load balancing market. 

Least Connections: Least connection algorithm sends network traffic to the servers with the least open connections. This algorithm is known for its capacity to handle new requests. 

Weighted Round Robin: Assigns weight to different servers and weighted servers considered to handle more traffic will get slightly more traffic. It is considered as the advanced version of a simple round robin algorithm. 

Least response time: Least response time algorithm directs traffic to the server with the quick response time. It is considered as the modern version of least connection method. 

IP Hash: Unites source and destination IP addresses & uses a mathematical function to perform conversion into a hash and determine specific server.

Network Load Balancer: The network load balancer algorithm technique distributes network traffic requests across multiple servers or instances.

Weighted least connections: Distributes traffic by prioritizing servers with the least active connections but also considers the server capacity(weight).

Application load balancer: Functions at layer 7 of the Open System Interconnection(OSI) model and is designed to intelligently distribute traffic based on application-specific protocols such as HTTP and HTTPs.

Hardware Load Balancer: Physical Appliance that distributes network traffic to various servers and enhances performance, availability, and scalability by stopping a single server from becoming overloaded.

DNS Load Balancer: Uses Domain Name System(DNS) to distribute traffic across multiple servers.

Global Server Load Balancing: Distributing web and application traffic across various servers in different locations.

Software Load Balancing: The application routes network traffic across multiple servers to distribute traffic and prevent overload.

Source IP Hash: Generates a unique hash key through the source and destination IP address of the client, and the key is used to allocate the client a specific server.

Random Load Balancing: Distributes incoming traffic requests randomly to the servers without any metrics or predefined patterns.

Resource-based load balancing: Distributes traffic according to real-time indicators recovered from the backend servers.

Virtual load balancers: Software-based solutions that distribute network traffic across multiple servers.

Trends in Load Balancing Market

Below are the substantial load-balancing market trends

 

Cloud-Based Load Balancing: 

To authorize multiple servers to share the same IP address cloud balancer uses IP anycast network addressing method. If your primary backend becomes unhealthy and fails to manage traffic, it diverts the traffic to other servers.

Hybrid and Multi-Cloud Deployments: 

The modern trend of hybrid and multi-cloud deployment in applications where in hybrid model, you merge public and private cloud and in multi-cloud, you merge cloud services from various cloud service providers. This approach enables smooth server operations for your application and makes it easier to respond to the incoming traffic requests appropriately. 

AI and Automation: 

A sudden network traffic surge makes it quite challenging to perform manual tasks such as resource allocation, predictive maintenance, and traffic optimization. However, the AI and Automation trend eliminates these challenges with a dynamic approach and eliminating extra time and efforts.

Edge Computing: 

Companies allocate edge servers at the edge of the network to increase the response time of the source. Edge computing enables the response time through quick data, storage, and computing process of the server with accurate data transmission from source to destination.

Security Integration: 

ACL configuration and firewall integration in load balancer allows you to manage inbound and outbound network traffic in your network. The load balancer tool acts as a medium of security layer and actively monitors the traffic and blocks malicious content from the network.

Containerization & Microservices: 

Businesses utilizing Kubernetes and Docker are the prime examples of containers and microservices trends in the load balancing market. Using containers as a service platform, businesses can leverage the network traffic deployment effectively and manage network traffic.

Software-defined networking: 

The traditional method of networking drawbacks in network management has introduced software defined networking where network configuration according to security preferences improved the overall performance. Software defined networking approach allows grouping of network and segmentation to enhance performance and security. 

Application performance optimization: 

The load balancing uses appropriate algorithms to distribute traffic efficiently. Monitoring server health and executing caching enhances ideal resource utilization and responsiveness. A load balancer can improve application performance by distributing traffic, reducing latency, optimizing resource utilization, and improving availability. By frequently monitoring the health of the servers, the load balancer dynamically removes unhealthy servers from the pool.
