Cloud Clustering & Load Balancing Services

Businesses today achieve scalability and high performance with the efficient mechanism of Load Balancing, which ensures uniform distribution of dynamic workload across multiple nodes. A High Performance Computing Cluster is similar to a general client-server computing model, but the similarities end here.

The HPC cluster combines the computational power of both nodes and computers in a single operating system. While the internal workings physically and logically different, the system works as a parallel application. An example could be the HPC Iitd, which is used for nationwide centralized coordination in India, on a network of numerous computers configured identically.

Goognu’s load balancer services not only achieve redundancy and eliminate overloading, but also improve the overall performance in a powerful computing environment. We help you achieve flexibility in handling traffic, reduction in downtime, and an increase in performance.

Cloud Load Balancing

A load balancing cluster for cloud computing works in the method of splitting computing properties and workloads or application demands by distributing the enterprise resources among numerous servers or computer networks. Goognu’s cloud load balancers hold the rapidly growing internet traffic circulation and existing workload demands, thereby preventing overloading of servers.

Enterprises can overcome this problem with either of these two elementary solutions:

• Single-server solution: Upgrading the existing server to a higher performance server, which may need a further upgrade to meet growing demands.
• Multiple-server solution: A cost-effective and scalable server cluster that increases reliability through redundancy. Goognu’s server cluster systems support all types of services, such as HTTP, FTP, SMTP, POP/IMAP, and DNS.

Load Balancer Types

Load balancers come in hardware and software load balancer types. AWS Load Balancer classifications are as follows:

Application Load Balancer

AWS Application Load Balancer makes routing decisions based on the application layer and path. Supporting dynamic host port mapping, you can route multiple requests to more than one ports on each container instance.

Network Load Balancer

Using a default flow hash routing algorithm, the load balancer opens a TCP connection to the selected port. Elastic Load Balancer in AWS can make routing decisions at the TCP/SSL layer and handle millions of requests at a given time.

Classic Load Balancer

Amazon Load Balancer makes routing possible at either TCP/SSL or HTTP/HTTPS layers. A fixed relationship is required to make static mapping between the container instance port and the load balancer port.

Goognu’s Load Balancing In Cloud Computing: Techniques

Load Balancer Server farm or a network of servers from Goognu follow simple to complex methods depending on the current level of requests to ensure uniform distribution. Factors that influence the technique and algorithm chosen at the time of the request are the status of the servers and network, the application being served, and the type of server.

Round Robin

A DNS Load Balancing server returns the requests for the IP Addresses with the same domain name, but a unique IP address, in a rotating sequential manner.

Weighted Round Robin

Built on the simple Round Robin method, here each server gets a static numerical weighting. Higher the rating of a server, the more requests it gets.

Chained Failover

This is a Fixed Weighted method, where predetermined ratings are given to servers, and if the requests are more than acceptable, they go to the subsequent servers.

Least Connection

New requests are distributed to a low-current load server, one with the lowest number of active sessions at a given time.

Weighted Least Connection

If the number of active connections is the same for two servers, then the server with an assigned higher weighting gets the new request.

Weighted Response Time

Servers under heavy load will respond more slowly, and hence, the fastest responding server at a particular time gets the current request.

Layer 7 Content Switching

URL Rewriting or Layer 7 Content Switching uses application layer information to determine the best-suited server to process the datapackets in real-time.

Agent-Based Adaptive Load Balancing

The load balancer uses real-time information about the current load of each server in conjunction with techniques like Weighted Round Robin.

Global Server Load Balancing

In case a primary server is down, the load balancer diverts the traffic to a disaster recovery site and High Availability is achieved.

Software Defined Networking- Adaptive

Goognu’s SDN Adaptive method combines information about upper networking layers and the lower layers, to allocate requests.

Source IP Hash

A unique hash key generated connects the IP addresses of source and destination. Even if the session is broken, the key will be regenerated and the client stays connected to the same server.

Active Directory Traffic Steering

Based on the AD group, the client traffic can be steered to appropriate Real Servers in a Virtual Service. If the selected group Real Servers are not available, the VS uses the assigned scheduling method.

Open Source Load Balancer

For free-flowing and flawless web infrastructure, Goognu uses a combination of open source cloud computing solutions to distribute the traffic across multiple backend servers.
