A technician is configuring a load balancer for the application team to accelerate the network performance of their applications.
The applications are hosted on multiple servers and must be redundant.
Given this scenario, which of the following would be the BEST method of configuring the load balancer?
Click on the arrows to vote for the correct answer
A. B. C. D.D.
Load balancers are used to distribute incoming network traffic across multiple servers to enhance the network performance of applications. The technique used to distribute traffic across multiple servers is referred to as load balancing method. In the given scenario, the application team requires redundancy and acceleration of their applications through a load balancer.
Now, let's explore each of the given load balancing methods and determine which one is the best option in this scenario:
A. Round-robin: In round-robin, the load balancer distributes incoming traffic equally among the servers in a cyclic manner. This method ensures that each server receives an equal amount of traffic, and it is suitable for environments where servers have the same capacity. However, if the server capacities are different, some servers may get overloaded, leading to network congestion and reduced performance.
B. Weighted: In weighted, the load balancer distributes traffic based on the capacity of each server. The more capable servers receive more traffic compared to less capable servers. This method ensures that traffic is efficiently distributed across servers according to their capacity. However, it does not provide redundancy, which is required in this scenario.
C. Least connection: In least connection, the load balancer distributes traffic to the server with the least number of active connections. This method ensures that each server handles an equal number of connections, which reduces the possibility of overloading servers. However, it does not provide redundancy, which is required in this scenario.
D. Locality-based: In locality-based, the load balancer distributes traffic based on the location of the user, which ensures that users are connected to the server nearest to them. This method is suitable for environments where users are located in different geographic locations. However, it does not provide redundancy, which is required in this scenario.
Based on the above discussion, the best method of configuring the load balancer is "Round-robin" as it ensures that each server receives an equal amount of traffic, and it is suitable for environments where servers have the same capacity. Furthermore, round-robin also provides redundancy by distributing traffic across multiple servers. Therefore, it is the most suitable method for the given scenario.
