Load Balancing

In a nutshell

Load balancing is a technique to distribute workload
across two or more computers, data centres or other IT resources. This enables optimal resource utilisation, maximise throughput, minimise response time, avoid overload, deliver high availability and business continuity.

Load Balancers have evolved into Application
Delivery Controllers (ADC), which improve application delivery and performance with features such as caching, compression and acceleration.

Organisations have become heavily reliant on ecommerce/ebusiness and the use of the Internet to provide services and generate revenue.

Traffic volumes have risen dramatically, often creating contention for constrained resources (e.g. network bandwidth, system capacity). Applications have become more complex. Support for real-time interaction and multimedia content has placed even greater demands on computing infrastructure.
What these changes and trends expose, in particular, is the need for enterprises to step up from a simple load balancing solution to a more comprehensive application delivery solution — a solution that addresses not just scalability and availability of the application environment, but application performance and security as well.

Promoting Green Computing

CIO’s are under constant pressure to deliver high quality enterprise applications more quickly at lower cost while reducing their businesses carbon footprint.

ADC provide lower power operation by providing multiple features from a single solution, reducing server farms in excess of 50-80% and optimising bandwidth usage.

With the Cloud computing initiative and increasingly trend to virtualise infrastructures, ADC’s are available as a virtual appliances which run on hypervisors, whi

Key benefits of Load Balancing

Application Delivery Controllers and Optimisation

Load Balancing enables enterprises to:

• Delivers high performance load balancing and Layer 7 content switching to ensure fast, reliable application delivery
  
• Wide range of Physical and Virtual appliances available for SMB and Enterprise customers
• Proven technology adopted by leading web service providers such as Google, MSN, Ebay and Yahoo
  
• Accelerates applications for any user up to 5x
• All-in-One Solution / Centralised Management
• Reduce server infrastructure costs by preventing server sprawl

Ensure Application and Network Security

Ensure web application security with native
Intelligence to protect against application threats and DoS attacks, integrated XML security to protect all Web 2.0 applications and strong authorisation controls to permit only sanctioned access to sensitive information. ADC can prevent loss of valuable
corporate and customer data, allows remote access while blocking unauthorised users, aids in compliance with regulations such as PCI-DSS and reduces the number of point products deployed. Defend against buffer overflow exploits, SQL injection attempts, cross site scripting attacks and more.

Business Continuity & DR

Load balancing ensures application uptime and no single point of failure by directing users only to the right application resource. GSLB load balancing ensures that applications are always available to all users worldwide, overcoming downtime common during outages and disasters. Fully redundant deployments also ensure high availability.

Lower total cost of ownership

ADC delivers up to 80 percent savings in training, power, space and overall costs. It delivers more applications to more users while reducing server costs by up to 60 percent. ADC offloads intensive and repetitive tasks off servers, holds dynamic content generated by servers in in-memory cache and shields servers from unwanted traffic. This reduces the number of servers and network devices, and allows you to deploy new Web 2.0 applications without extensive infrastructure changes.

Improved operational efficiency

As enterprises grow, IT need to rapidly increase bandwidth and computing capacity – often in the form of increased Internet capacity, IT services support and server resources. The resulting expenditures are costly in terms of capital and people needed to operate and manage delivery
infrastructures.

Intelligent Load Balancing and Content Switching

ADC’s provides comprehensive layer 4-7 traffic
management. Deployed in front of application servers, they deliver fine-grained load balancing of client requests to ensure optimal distribution of traffic. Intelligent traffic management and extensive server health checks provide greater business continuity and eliminate the application server as a single point of failure. It is easy to define traffic management policies based on layer 4 traffic information (protocol and port number), as well as application-layer information such as URLs, application data type or cookie.

Guard against Denial of Service Attacks

Denial of Service (DoS) and Distributed Denial of Service (DDoS) attacks are assaults on a network that flood it with so many additional requests that regular traffic is either slowed or completely interrupted

ADC solutions provide intelligent Layer 4 / Layer 7 DoS and surge protection to ensure your web services are robust and available
