Load Balancing is a technique (usually performed by load balancers) to spread work between many computers, processes, disks or other resources in order to get optimal resource utilization and decrease computing time. A load balancer can be used to increase the capacity of a server farm beyond that of a single server. It can also allow the service to continue even in the face of server down time due to server failure or server maintenance.

A convergence of potentially conflicting trends is creating a perfect storm for IT professionals tasked with providing secure, reliable access to applications and other critical corporate information. So how can IT avoid the strain on corporate networks as more users attempt to access desktop infrastructures - including applications and services- from remote offices or through mobile devices? Learn how boosting application delivery and response time across a global network can improve collaboration and productivity among an increasingly global and mobile workforce.

There are more people on earth than total IPv4 addresses, and they're expected to run out by the end of 2011. Preparing for the transition now can help you maintain business continuity during the changeover while taking advantage of immediate business benefits.
If your organization's servers run applications that are critical to your business, chances are that you'd benefit from an application delivery solution. Today's Web applications can be delivered to users anywhere in the world and the devices used to access Web applications have become quite diverse.
At a projected market of over $4B by 2010 (Goldman Sachs), virtualizationhas firmly established itself as one of the most importanttrends in Information Technology. Virtualization is expectedto have a broad influence on the way IT manages infrastructure.Major areas of impact include capital expenditure and ongoingcosts, application deployment, green computing, and storage.
The idea of load balancing is well defined in the IT world: A network device accepts traffic on behalf ofa group of servers, and distributes that traffic according to load balancing algorithms and the availabilityof the services that the servers provide. From network administrators to server administrators to applicationdevelopers, this is a generally well understood concept.
Application Delivery Controllers understand applications and optimize server performance - offloading compute-intensive tasks that prevent servers from quickly delivering applications. Learn how ADCs have taken over where load balancers left off.
Many products on the market today promise to measure and manage "end user experience" - but how can they if they are only testing from a central location? Download this whitepaper to learn how to see and solve user experience problems from their point of view. We'll show you to measure actual application traffic from the user perspective and other critical points in the network so you can pinpoint and understand where the issue is, either the end points or the path between them.
Abstract: Learn the essential considerations when evaluating network management tools and processes. We'll show you how most network management systems fail to deliver a complete picture of network and application performance.and that puts the organization at risk. Being aware of the potential shortcomings of an incomplete NMS is essential.
In this whitepaper we'll cover three common shortcomings, the possible consequences, and we'll highlight six key capabilities to be aware of when evaluating your network management tools and processes in order to avoid these shortcomings and associated risks.
Internal testing only allows you to see potential issues from within your own controlled environment, and does not test for the countless different scenarios in which a customer could be accessing your site. Find out the benefits of external load testing.
Enterprises and equipment vendors are learning the value of a complete readiness assessment before deploying VoIP across an organization. The assessments are a critical step to a successful VoIP deployment, but many enterprises do not perform an assessment because of cost or because after performing a baseline on network utilization, they assume that their network has enough bandwidth to accommodate the voice traffic. This white paper explains why it is essential to perform a readiness assessment both for initial VoIP deployment and also for expansion projects to avoid unplanned additional costs and deployment delays.
With increasing bandwidth demands, network professionals are constantly looking to optimize network resources, ensure adequate bandwidth, and deliver high performance. Often, buying more bandwidth is not a priority or an option due to limited budgets and pressure to reduce IT costs.
When a business expands an existing facility,
adds a new location, incorporates an influx of
new users, or upgrades an existing infrastructure
- it's vital to ensure network readiness and
validate infrastructure changes to optimize
network performance, minimize user downtime
and reduce problems after implementation. This
white paper describes a methodology to manage
network changes that meets the need for speed
of implementation without sacrificing accuracy.
Network installers have completed a new
local area network segment. New cabling
was installed to the appropriate work areas
from the equipment closets. New switches
and access points were installed, patched into
the cabling plant and configured. How will the
network perform? This newly installed network
needs to be validated to prove the installation
was done correctly, that the LAN will operate
trouble-free, and that users will be satisfied
with the performance.
An Ethernet service provider needs to demonstrate to his customer that the service he is providing is compliant with the service level agreement. A network installer needs to demonstrate the functionality of a newly turned-up Ethernet link. A network troubleshooter needs to resolve complaints about slow networks. Ethernet performance measurement can help. Various metrics can quantify and characterize performance. Test plans can be written to satisfy varying organizational objectives. This white paper will describe advancements in field measurement of end-to-end Ethernet performance.
