Load balancing consist of to distribute the client requests to multiple application servers that run locally on client infrastructure. Cloud load balancing consist of to distribute the client requests to multiple application servers that run in a remote environment. Like other methods of load balancing, the cloud load balancing allows maximizes the application performance and availability; also it provides a reduction in cost and service management to match demand.
More and more companies run all types of applications in the cloud. A company could use a CRM in the cloud, as Salesforce.com to store client information, or using a ERP system cloud to manage product data, or using a web hosting provider like Google to host its website, and others cloud providers to run custom applications. Therefore, when much of the computing infrastructure of the company is hosted in the cloud, it make sense to hire cloud load balancers.
Traditional load balancing solutions are based on proprietary hardware hosted in a data center, and require IT staff to install, adjust and maintain the system. Only large companies with big budgets can take advantage of the benefits that load balancers give, like performance and reliability. In the age of cloud computing, the solutions based on hardware have another serious drawback: they are not compatible with the providers of cloud infrastructure, because the providers of cloud infrastructure don't allow proprietary hardware in its environment.
Fortunately, load balancers based on software offer benefits of performance and reliability offered by solutions based on hardware to a much lower cost. Due to they are running on the hardware of cloud providers is achieved a execution in the cloud like any other software application, and therefore the product software is affordable even for smaller companies.
"Software load balancers offers benefits of performance and reliability over hardware solutions."
Cloud load balancing benefits arising from the global and scalable nature of the cloud.
The ease and speed of expansion of the cloud means that companies can handle workload peaks without degrading performance through the collocation of a cloud load balancer in front of a group of application instances, they can be managed depending on demand.
The ability to host an application in multiple cloud centers around the world can increase reliability. For example, If a power outage hits the data center where the client application is hosted, the cloud load balancer allow manage the traffic and redirect to other server anywhere in the world.
ZVNcloud is significantly much easier to manage than any hardware solution with similar capabilities. Furthermore ZVNcloud can be easily deployed in cloud infrastructure.
Application with fault tolerance could be created with ZVNcloud load balancer, using an automatic balancing to manage the traffic of its servers from internet, and ensure that only the access to services that are in good condition receive traffic. ZVNcloud load balancer can be configured to balance the incoming traffic load in an application. Balancing function can detect the service state and when it detects messed services, ZVNcloud load balancer cease to manage traffic to the affected system, dispersing the load to different points of access to the service that they are in good condition. If all the devices in service are in poor condition, message error and redirects personalized could be configured by the user, once your service is operational again on at least one device, ZVNcloud load balancer will resume load balancing to the devices composing the service.
GSLB profile of ZVNcloud load Balancer, which is balanced by DNS, improves application availability.
GSLB profile of ZVNcloud Load Balancer offers you a low bandwidth consumption due to the client receives through a DNS response, the order to connect to the most appropriate application server at that moment. If the application does not respond, ZVNcloud Load Balancer disables the unavailable server and direct the client connections to an alternative node.
HTTP profile of ZVNcloud Load Balancer can be used for advanced balancing of HTTP services.
HTTP profile of ZVNcloud Load Balancer offers you advanced balancing properties. You can perform session persistence based on localized values in the HTTP service, like cookies, http headers, parameters in the URI or IP source. HTTP profile of ZVNcloud Load Balancer will make connections in their nodes, and you can always know the source IP. If the application does not respond, HTTP profile of ZVNcloud Load Balancer disables the unavailable server and direct the client connections to an alternative node. In addition message error personalized can be configured by the user.
L4xNAT profile of ZVNcloud Load Balancer can be used for any TCP or UDP protocol.
L4xNAT profile of ZVNcloud Load Balncer offers you a very high performance and manages much more concurrent connections. That performance improvement counteracts the advanced content handling that HTTP profile profiles could manage. Use the L4xNAT profile of ZVNcloud Load Balancer for applications that are managing high number of concurrent users.
