Cloud load balancers help in on-demand, scalable traffic management. They are mostly required during rapid online traffic spikes as these situations challenge even the most efficient websites and applications. These kind of load balancers have become extremely popular among small-to-large businesses because even a brief outage can cost a company thousands of visitors and millions of dollars.

Cloud Load Balancers – How do they really Work?

Online traffic is managed by these balancers by distributing workloads throughout multiple servers as well as resources. Therefore, these balancers maximize performance of workload, thereby preventing overload all the time. This ensures that the user gets seamless experience.

Features of Cloud Load Balancers

There are 3 main features associated with these balancers –

#1 Dedicated IP Address

Every load balancer comes with a specific IP address. The same remains static even when the load balancer is being used.

#2 Supports SSL Termination

Secure online transactions are available because of the public key encryption and decryption offloads, which again provides redirect from HTTP to HTTPS.

#3 High Availability

Cloud load balancers ensure that the users get high availability all the time. In this kind of cases, load balancing takes place in cloud computing and the workloads are distributed among various resources of computing. In fact, these services, in real life, reduce cost to a large extent as they bring down the costs associated with document management systems. Availability of resources is also being maximized here.

Comparison between Cloud and DNS Load Balancers

It needs special mention here that DNS (Domain name System) load balancing is not what we are discussing here. Cloud load balancers are quite different from the DNS load balancers. In the latter case, software or hardware are used for performing function. However, in case of cloud load balancers, the services offered by different computer network companies are used.

Cloud load balancers are more beneficial than DNS load balancers because the load transfer to servers take place on a global scale rather than across local servers. Even when there is any local server outage (due to unforeseen situations), the user faces no interruption. This is because the cloud load balancing feature delivers data from closest regional server.      

In case of DNS load balancing, DNS directives can be enforced only in every TTL cycle. In fact, if there is any scenario of switching between servers, it may take several hours during scenarios such as failure of server or server lag. Uneven performance can be experienced as the internet service providers may be late in reaching the new server before the internet service providers. However, such problems will not be experienced in cloud load balancing. The response time is improved by a significant amount by cloud load balancers through remote session routing to the data centers that are the best performing ones.  

Cloud Load Balancing Benefits

There are three specific advantages of cloud load balancing and they are availability of service users, flexibility, and cost. In fact, these are the main reasons wh6y cloud load balancers are becoming so popular.
