Web-Scale IT Architectures and Techniques Grow in Demand
Businesses will also need to make a special effort to acquire and grow the capacity and performance management skills, a Gartner report found.The availability of capacity and performance management skills for horizontally scaled architectures will be a major constraint or risk to growth for 80 percent of major businesses by 2016, according to a report from IT research firm Gartner. Agile infrastructures demand that infrastructure and operations (I&O) managers acquire the performance management skills present only in Web-scale IT, and while major organizations will need to maintain and sustain their conventional capacity-planning skills and tools, they will also need to regularly re-evaluate the tools available. Businesses will also need to make a special effort to acquire and grow the capacity and performance management skills that are rarely evident outside the Web-scale IT community, the report said. Gartner research director Ian Head said to take advantage of Web-scale IT approaches to capacity and performance management, IT architects need to fully embrace stateless application architectures and horizontally scaling infrastructure architectures.
"Organizations managing such services need the ability to rapidly assign and de-assign resources to each service, as well as the ability to scale linearly and continuously as more resources are added or removed," Head said in a statement. "They also need high levels of resiliency that will allow sections of the infrastructure to fail without bringing the services down. Designing the underlying infrastructure for horizontal scalability, high degrees of fault-tolerance and rapid, incremental change is a key prerequisite for effective Web-scale operations."
