Load balancing distributes load across multiple servers. It enables you to carry out scheduled maintenance work and, should a server fail, there's one ready to take over.
With this increased level of redundancy, having a load balancing solution in place allows your end-users to have a seamless, uninterrupted and unaffected experience in any situation.
Both layer 4 and 7 load balancing options are available , improving the availability, performance and end-user experience of your business critical applications and websites.
Load balancing gives you the ability to removes single points of failure from an infrastructure, whilst facilitating simple horizontal expansion to optimise infrastructure for performance.
Scalability and future proofing are added benefits, allowing you to scale horizontally in a seamless fashion.
Additional extra functionality can be delivered including Encryption offloading, basic DDoS protection and Web Application Firewalling.
The Bunker offers a wide range of solutions tailored to customer requirements and applications. We can offer load balancing solutions based on Open Source technologies or as appliances on physical, virtual and shared platforms.
We provide you with a highly available, scalable and high performance platform to suit your needs.
With the availability of data being ever more critical, the ability to load balance between servers is a must have for many businesses, allowing critical security patching and routine maintenance to be performed with zero impact to the service.
At Layer 4, a load balancer has visibility on network information such as application ports and protocol (TCP/UDP). The load balancer delivers traffic by combining this limited network information with a load balancing algorithm, such as round-robin, and by calculating the best destination server based on least connections or server response times.
At Layer 7, a load balancer has application awareness and can use this additional application information to make more complex and informed load balancing decisions. With a protocol such as HTTP, a load balancer can uniquely identify client sessions based on cookies and use this information to deliver all a client’s requests to the same server. This server persistence using cookies can be based on the server’s cookie or by active cookie injection where a load balancer cookie is inserted into the connection.
