Round-Robin Load Balancing
WebLogic Server uses the round-robin algorithm as the default load balancing strategy for clustered object stubs when no algorithm is specified. This algorithm is supported for RMI objects and EJBs. It is also the method used by WebLogic proxy plug-ins.
What is load balancer and how it works?
Load balancers improve application availability and responsiveness and prevent server overload. 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 the main purpose of a load balancer?
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.
What is meant by load balancer?
A load balancer manages the flow of information between the server and an endpoint device (PC, laptop, tablet or smartphone). A load balancer is a hardware or software solution that helps to move packets efficiently across multiple servers, optimizes the use of network resources and prevents network overloads.
What is load balancer and its types?
Elastic Load Balancing supports the following types of load balancers: Application Load Balancers, Network Load Balancers, and Classic Load Balancers. Amazon ECS services can use these types of load balancer. Application Load Balancers are used to route HTTP/HTTPS (or Layer 7) traffic.
What is an example of a load balancer?
The following are few examples of software load balancers: HAProxy – A TCP load balancer. NGINX – A http load balancer with SSL termination support. (install Nginx on Linux)
What happens if load balancer goes down?
If your load balancer now loses its internet connection, power, or breaks for any reason, you will now lose connection to all of your backend servers. We call this moving up the single point of failure, as you have moved the single point of failure up from the application servers to the load balancer.
How many load balancers are there?
How many load balancers do I need? As a best practice, you want at least two load balancers in a clustered pair. If you only have a single load balancer and it fails for any reason, then your whole system will fail. This is known as a Single Point of Failure (SPOF).
Layer 4 load balancing manages traffic based on network information such as protocols and application ports without requiring visibility into actual content of messages. This approach is effective for simple load balancing at the packet level.
What layer is a load balancer?
Layer 7 load balancing operates at the high‑level application layer, which deals with the actual content of each message. HTTP is the predominant Layer 7 protocol for website traffic on the Internet.

What are the load balancing methods?
Load balancing methods are algorithms or mechanisms used to efficiently distribute an incoming server request or traffic among servers from the server pool. Efficient load balancing is necessary to ensure the high availability of Web services and the delivery of such services in a fast and reliable manner.
Is a load balancer necessary?
Every application needs a load balancer, so your system for provisioning an app should include a load balancer automatically, whether as software or a configuration within a hardware load balancer.
When should you use a network load balancer?
When to Use Network Load BalancerA demand for seamless support of high-volume or spiky inbound TCP requests.A need to support an elastic or static IP address.To support more than one port on an EC2 instance while using container services.
What is load balancer in cloud computing?
Cloud load balancing is the process of distributing workloads across computing resources in a cloud computing environment and carefully balancing the network traffic accessing those resources.
What problem does adding a load balancer solve?
Load balancers help solve the performance, economy, and availability problems.

The Random load balancing method should be used for distributed environments where multiple load balancers are passing requests to the same set of backends. For environments where the load balancer has a full view of all requests, use other load balancing methods, such as round robin, least connections and least time.

Note: If you created the load balancer in a different network than the Oracle WebLogic Server domain network with nonoverlapping CIDRs, you must create a Local Peering Gateway on both the domain network and load balancer network and add a route table for the subnet for WebLogic domain and the load balancer subnet to use the respective Local Peering Gateway.

WebLogic Server Web Server plug-ins currently support TLS v1.2 communication between Web Servers and WebLogic Server back ends. Customers who want to enable TLS v1.3 support through a load balancer to WebLogic Server back ends should evaluate load balancer alternatives such as hardware load balancers, or software load balancers such as NGINX.
