FAQs – Load Balancer Software
1. What is a load balancing application?
Load balancing software facilitates the efficient distribution of network traffic. This app receives traffic from different sources and distributes traffic across data servers. Additionally, the app serves as a reverse proxy, retrieving resources from servers and returning them to clients, appearing as if they had originated from a proxy server.
2. Why is it important to apply load balancing to the cloud?
Load balancing is important to deploy for your cloud environment to ensure efficient traffic management. The application allows you to manage multiple servers that have the same configuration for the efficient distribution of network resources.
3. How does a load balancer work?
Load balancers are Application Delivery Controllers (ADCs) that drive modern web applications. Load balancing is performed on a virtual machine or a standard server. It is traditionally paired with a Hardware Load Balancing Device (HLDs) to distribute traffic among servers, thereby resulting in an efficient and reliable network with maximum uptimes.
4. What are the different types of load balancing apps?
Software load balancing apps can be installed onto a server or used as a load balancer as a service (LBaaS). A cloud service provider manages the LBaaS and is responsible for installing, upgrading, and configuring the application.
5. What are load balancing algorithms?
Load balancing algorithms determine how traffic is sent across different servers.
There are different types of load balancing algorithms that are briefly discussed below:
- Round-robin Algorithm is the simplest method that involves moving the requests in the same order to available servers.
- Least-time Algorithm selects servers based on the least number of active requests and fastest processing speed. The algorithm may integrate weighted algorithms that give preference to servers with higher memory, power, and capacity.
- Least-connections Algorithm sends requests to servers with the least workload. The algorithm sends requests to the least busy servers.
- Hash-based Algorithm assigns a hash key to the client and server IP addresses. The algorithm ensures that the requests from users are sent to the same server that contains data from the previous sessions. This results in an efficient network resource delivery.
Conclusions
We have reviewed the best load-balancing applications that are suitable for different cloud and application environments. You can select a platform that best meets your network traffic management requirements.
jetNEXUS is the best one for enterprises that want advanced traffic load management features.
