Don't get stuck in the networking jam 

Not surprisingly, portals, which are inherently web-based, featured at the top of the list of applications that businesses have web-enabled.

But businesses are also directly web-enabling certain key business applications, specifically to allow direct access to them from the outside. These include customer relationship management, supply chain management and enterprise resource planning. These applications are the most widely accessed by external organisations, those in which business management take the most interest and those that cause the most concern should access become unavailable.

And herein lies the problem. Opening up business applications to suppliers, customers and trading partners is a great idea if businesses want to automate and speed up certain processes. But, if to do this they are relying on an overused public network, these benefits are at risk if the network becomes too slow or fails.

Businesses that rely on web-enabled applications are aware of this conundrum; they have high expectations of internet performance and availability, but real concerns about the internet being able to deliver. However, most are proactive in trying to improve and guarantee performance.

The first thing many businesses do is throw more hardware at the problem, which will make no difference if the network is failing. They are also likely to place limitations on what their employees can do on the internet - this will reduce traffic over the parts they own (such as broadband connections in branches) and is likely to have a positive impact on productivity. But it will not do much to ensure web-enabled applications perform well over the internet.

To do this requires more subtle techniques. A minority have turned to hardware appliances from vendors such as Riverbed, Expand and Packeteer, which are designed to reduce, compress and accelerate traffic between branches and data centres. However, such products do little to help remote users on laptops or external users, unless there is also a PC-based software client for communicating with a data centre-based appliance. Some vendors are now starting to offer this capability.

Another way of guaranteeing a better and more reliable experience is to subscribe to a managed service, offered by vendors such as Akamai. Such services keep the internet connection between a user and the application under constant review and optimise the route and performance.
Appliances and managed services are not direct alternatives but are often complementary. In Quocirca's survey, about 25 per cent of respondents were using one or the other and of these about one-third were using both.

While the internet is becoming more essential for the delivery of inter-company business processes, ensuring optimum and consistent performance will become increasingly problematic as the internet's users compete for resources. Those businesses that achieve the most from web-enabling applications will be those who find the best ways of guaranteeing performance levels.
