Cloud Clustering & Load Balancing Services

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.
