Current acceleration methods are being delivered through three architectural options;  asymmetrical , symmetrical with hardware , symmetrical with hardware and software. 

However, while each option provides value, they each have their shortcomings:

1.      Asymmetrical solutions only accelerate outbound traffic to the user
2.      Symmetrical hardware based solutions are expensive to deploy, require management of additional hardware, and cannot address the needs of mobile or third-party users 
3.      Symmetrical hardware-software based solutions require software to be installed, and may not be acceptable to third parties or arms-length users 

The answer to all of these shortcomings is Acceleration On-Demand

An ever-expanding list of government and accounting regulations makes compliance more complex than ever before.

Financial and administrative organisations are under increasing pressure to archive and back up mission-critical data from branch offices and data centres to remote disaster recovery sites. With a growing volume of data combined with the current infrastructure, the challenge is to speed up transfers.

Your WAN, however, may be holding you back. Backup and applications perform slow and inconsistent. Data transfers take far too long. That means longer backup and upload times and the potential for financial loss.

Data Centre Virtualisation and the Worldwide Web:

Today’s challenges for big international companies are based on the requirements customers have to their services. No services, no information, no presence thus no income. Services these days begin at the counter of the internet because the distinction between the level off services provided on the web decide if the customers want to do business with a company or brand. Physical presence and location itself has diminished to a minimum because of the will to and the ability of customer mobility. The vast number of consumer goods and services has become a commodity because of companies being able to operate worldwide. With this, customers within the industry, face the challenge of bringing their expertise and services as well as goods to the internet. In example browser based booking to enable customers arranging all travel by means of the browser is a business strategy in itself and a necessity for survival. Competition is fierce. He who gets there first and gets the order in fast is bound to be the winner.

Accelerate Long Distance Transfers of Large Digital Files. When digital files need to be transferred beyond your home office, the wait can be agonizing with files taking too long to transfer even under the best network conditions.

Large files created and edited in today's working environment and production houses can account up to hundreds of megabytes or more. The WAN probably can't keep up with the fast-turnaround production schedules. Workflow gets interrupted. Deadlines can’t be met. Users get frustrated and productivity drops drastically. Studies show that when distances reach hundreds of miles and network latency rises, file transfer can slow to a crawl or even a standstill.

As WANs became more popular, it became apparent that Web applications suffered poor performance over the WAN due to the amount of non-productive protocol traffic, or “chattiness”, created by such applications. Similarly, Microsoft Windows Exchange (MAPI) and file share (SMB/CIFS) protocols proved to create an excess of protocol chat as well. While these protocols performed well on local area networks, the large number of round trips due to protocol chattiness significantly degraded application performance across high latency wide area networks.

Hackers and other malicious third parties are changing their strategy and are directing their attacks to the core of business applications. Unfortunately, applications themselves are often the weakest link in this story.

Security technologies that target lower layers of the Open System Interconnection (OSI) reference model are incapable of effectively protecting Web applications, which run at layer 7 (the application layer) of the OSI model. Layer 7 is the standard for application services such as the Hypertext Transfer Protocol (HTTP) for transmitting Web pages or the File Transfer Protocol (FTP) for moving files across the Internet.

Web application firewall technologies come into play as the only technology available capable of safeguarding the integrity of Web applications
