Understand Tiered Applications Is Important

"The data center strategy and architecture define the facilities that host IT services and the strategy for the placement of those services," Scott told about 2,500 attendees in a morning presentation. "It also defines the resiliency strategy (for example, for service outages, site outages, data corruption and so forth).

"The strategy and architecture is dependent on an understanding of the tiers of IT service criticality and associated service-level agreements. Most organizations have between three and five criticality tiers, with the highest tiers for their most mission-critical services with the most stringent service levels and the lowest tiers for the less-critical services with lower service levels."

When developing the strategy and architecture, an "end-state-type" architecture may be created, Scott said. However, execution of that strategy typically takes place over many years, because building and consolidating data centers and migrating services takes many years to implement.

"An integral part of any strategy-building exercise is understanding key market, business and technology trends, assessing their implications for your enterprise, and using them to build an intelligent plan that aligns with the business strategy, growth and risk profile," McGuckin said.

A strategic imperative, McGuckin said, is to assess and tier IT services according to mission criticality, identifying availability and recovery SLAs and strategies for achieving them.
