What is load balancing in database?
Database load balancing improves the distribution of database workloads across multiple computing resources. Load balancing aims to optimize resource use, maximize throughput, minimize response time, and avoid overload of any single resource.
What is load balancing & How does it work?
Load balancing is defined as the methodical and efficient distribution of network or application traffic across multiple servers in a server farm. Each load balancer sits between client devices and backend servers, receiving and then distributing incoming requests to any available server capable of fulfilling them.
What is load balancing and why would you use it?
What is load balancing? Load balancing is the process of distributing workloads across multiple servers, collectively known as a server cluster. The main purpose of load balancing is to prevent any single server from getting overloaded and possibly breaking down.
What is load balancing method?
Load balancing methods are algorithms or mechanisms used to efficiently distribute an incoming server request or traffic among servers from the server pool. … An incoming load or request to a server is shared across such replicated servers, and this process is known as load balancing.
What are the types of load balancing?

What is the use of load balancing?
Load balancers are used to increase capacity (concurrent users) and reliability of applications. They improve the overall performance of applications by decreasing the burden on servers associated with managing and maintaining application and network sessions, as well as by performing application-specific tasks.
How do you test load balancing?
To test network load balancing, connect a browser to the cluster IP address, for example: http://192.168.10.10. Refresh the screen multiple times. If the cluster is operating successfully, web pages from different machines in the cluster appear after each refresh.
How load balancing can be used to control traffic?
Load balancers, also referred to as application delivery controllers (ADCs), are hardware or software tools used for distribution of network traffic across servers. … In mission-critical applications where high availability is a requirement, load balancers can route traffic to failover servers.
How does Network Load Balancing Work?
The Network Load Balancing (NLB) feature distributes traffic across several servers by using the TCP/IP networking protocol. By combining two or more computers that are running applications into a single virtual cluster, NLB provides reliability and performance for web servers and other mission-critical servers.
How is load balancing implemented?
Edit: Load balancing can be implemented by DNS round robin too. Each DNS lookup call returns another IP address for the same domain name. The client choose an IP and connects to this server. Another client can use the next IP.
What happens if load balancer goes down?
If a single server goes down, the load balancer redirects traffic to the remaining online servers. When a new server is added to the server group, the load balancer automatically starts to send requests to it.
