Gartner Explains Why Digital Business Means Going Web-Scale

In the era of Digital Business successful companies are defined by their ability to respond quickly and effectively to transient business moments, and Gartner said that established approaches to IT infrastructure, operations and software development, still well suited to more traditional back-office applications of IT, simply do not offer the speed, flexibility and scalability needed to enable value creation from business moments.

Cameron Haight, research vice president at Gartner, while explaining why businesses that employ Web-scale IT are better positioned to thrive in the new digital world, said, “At the level of IT, Web-scale architectures found in companies like Facebook are highly scalable, because the performance levels are achieved by large numbers of efficient non-specialized nodes, and commodity x86 servers, rather than the kind of specialized systems that are often found running today’s corporate applications”.

He explained the concept as, “a term coined by Gartner to describe the new approaches to computing pioneered by cloud services firms such as Google, Amazon, Rackspace, Netflix, Facebook and so on”.

These approaches potentially enable orders of magnitude of improved service delivery when compared to many of their enterprise counterparts. Gartner has identified six elements to Web-scale IT: industrially-designed data centers, Web-oriented (or microservices) architectures, programmable management, velocity-focused processes, a collaborative organization style and an innovation-centric and learning culture.

Haigh added that “The combined resources of these many nodes are then pooled to create a computing fabric for allocation according to demand. Web-scale hardware is relatively inexpensive and readily available, and so are the blueprints for a Web-scale data center, through open-source projects. When more computing power or storage is needed, there’s no need to re-architect the entire system, just add more nodes. If a node breaks, just replace it with another because applications have usually been designed to accommodate infrastructure failure.

“Controlling the network of nodes is integrated software which – as opposed to hardware controls – can “re-program” the system to meet changing dynamics. The system is inherently resilient as data, metadata and operations are distributed across large numbers of small replaceable nodes, and possibly even across multiple data centers.

“The increased scalability and efficiency of this form of IT can be used to rapidly enable new digital business models in almost any industry, while lowering costs – essentially it is bringing economies of scale (and speed) to computing power”.

He added that each business will have different needs, strategies and priorities that can be served by this revolution, but bringing the principles of Web-scale IT into the organization is a step towards being able to rapidly enable digital products and services faster than the competition, and in tune with market demand.

Thus, “the flexibility and agility enshrined in the IT infrastructure enables a DevOps approach that can in turn make IT the driver of innovation and profit”.

In addition, through a mixture of cloud services and in house equipment that is right for their organization, a Web-scale approach can turn IT into a tangible competitive advantage for smaller companies in the way it has for internet giants, he said.

Haigh maintained that web-scale techniques are applicable to organizations of many sizes, and can be adapted to support a wide range of business outcomes.
