The pervasiveness of load balancing technology does not mean it is universally understood, nor is it typically discussed other than from a basic, network-centric viewpoint. This White Paper thoroughly explains load balancing and strips away some of the mystery and magic from basic load balancing practices.

One of the unfortunate effects of the continued evolution of the load balancer into today's application delivery controller (ADC) is that it is often too easy to forget the basic problem for which load balancers were originally created-producing highly available, scalable, and predictable application services. This White Paper describes the Evolution of load balancing devices to Application Delivery Controllers.

Information security personnel suffer from information overload on a nearly daily basis, but need to sift through myriad articles, reports, blogs, logs, and scans to do their jobs. Information is vital to successful web application security strategies, whether it be information about a new attack, a new twist on an existing attack, or identifying weak points in web applications. Investments in security solutions have to provide a clear value, which equals additional time spent collecting and documenting proof of this value. The latest version of F5 BIG-IP Application Security Manager(tm) (ASM), v10.1, addresses information overload and the need for agility in implementation.

Many organizations choose to run data traffic and network management traffic over the same network links. This paper will discuss why it is critically important to segregate network management and control data traffic to ensure that problems can be solved even when the network is melting.

By working collaboratively with partners that build some of the most widely deployed network management tools in the industry, F5 provides the bridge between application system and network infrastructure management. Using third-party tools such as HP Network Node Manager i and Microsoft System Center Operations Manager, it has never been easier to manage F5 BIG-IP devices.

The ability to load balance some protocols requires a deep understanding of the way in which the applications that use those protocols behave. Protocols that are both asynchronous and communicate bidirectionally are challenging to scale for most load balancing solutions because they do not have the ability to extract and route requests at a message level and are inherently tied by their architecture to load balancing based on connections. F5 TMOS architecture provides the means by which F5 is able to quickly implement support for message-based protocols such as Diameter, RADIUS, and LDAP. TMOS enables BIG-IP Local Traffic Manager to extract and act upon message-level information, providing turnkey scalability and high availability while maintaining the ability to extend and adapt that functionality through iRules.

By providing a unified Application Delivery Networking platform, F5 BIG-IP offers the ability for organizations to adopt a single platform for all its application delivery needs. Adopting an organizational standard for application delivery can reduce management and administrative costs and improve the ability of the organization to migrate smoothly from traditional to emerging application architectures, and address the unforeseen issues that always arise in the wake of the introduction of new initiatives.

While it is important to understand the numerous benefits F5's BIG-IP application delivery networking products bring to an organization, such as high availability, improving application performance, optimizing infrastructure, and providing unique application security, the goal of this White Paper is to explore a more fundamental business and technical problem plaguing today's organizations and how BIG-IP, specifically version 9.4 and the 8800 platform, solves it.

The F5 universal access approach is based on F5's FirePass product, Secure Sockets Layer Virtual Private Network (SSL VPN), which is integrated with F5's BIG-IP Local Traffic Manager. This integration establishes F5 as the only vendor in the industry that can unify and centralize security and access control for remote, wireless LAN (WLAN), and Local Area Network (LAN) users, while scaling to meet the throughput requirements for unified access.

F5’s dynamic control plane is a real-world embodiment of the dynamic services model. F5 solutions provide IT organizations the ability to grow beyond static data centers, manage movement and migration of their applications and data down the hall or around the world, support demanding and ever-increasing mobile users, offer centralized and consistent security enforcement and global, dynamic measurement of real-time application performance. With this approach, F5 customers are better equipped to mitigate the complexity and costs of the move toward cloud computing, enabling them to unleash the true potential of on-demand IT.

The amount of file data in the enterprise is growing at unprecedented rates. In addition, data is being retained for longer periods of time due to business and regulatory constraints. While not all this data is critical to the day-to-day business operations of the organization, it must all be stored, protected and remain readily accessible should the need arise.

The goal of virtualization in the data center is to help the enterprise achieve a business goal, whether that goal is consolidation, reduced management and head count costs, disaster recovery, or even “going green.” And with this, the pinnacle of virtual solutions is to architect and deploy the complete Virtual Data Center.

The new F5 VIPRION chassis brings not only performance and capabilities beyond today's demands, but also creates cost efficiencies that will appeal to accountants and management everywhere. This White Paper highlights some unexpected savings that the deployment of the VIPRION system brings to the table.

This white paper describes the five different levels of virtual data center maturity progession.

This White Paper focuses on virtualization as it pertains to the data center. Before considering any type of data center virtualization, it's important to define what technology or category of service you're trying to virtualize. This White Paper describes eight different categories of virtualization so readers thoroughly understand the differences (and similarities) between the definitions of virtualization.

VMware Infrastructure products provide the next generation virtual platform for the new data center, but they don't virtualize the network or application delivery. This White Paper details how the F5 BIG-IP LTM works with VMware to provide truly virtualized Application Delivery Networking.

This White Paper discusses new technology developed by WhiteHat Security and F5 Networks that enables organizations to immediately mitigate discovered vulnerabilities using a web application firewall.

This White Paper describes how F5's WANJet device can dramatically accelerate CIFS transactions. Each WANJet appliance has a deep understanding of the CIFS protocol and can therefore act on behalf of a CIFS client and server to make the interaction between the two much more efficient.

The F5 WANJet product uses Transparent Data Reduction (TDR) technology to address bandwidth challenges. This White Paper explains how WANJet, using TDR, delivers LAN-like application performance over the WAN, accelerating file transfer, email, client server applications, data replication, and others while delivering predictable, fast performance for all WAN users.

The demand for (and benefits of) web-based interfaces combined with an increasingly mobile and distributed workforce has exposed inefficiencies inherent in the browser, the network and its protocols, and the data center. These inefficiencies create performance problems for applications that continue to be magnified by emerging technologies like Web 2.0 and SOA. This White Paper details how F5's approach to Application Delivery Networking eliminates the bottlenecks inherent in browsers, in the network, and in the data.

Companies today are moving more and more of their mission-critical applications and data into web browsers.
