Organizations are iterating over multiple decision points to provide the growing IT infrastructure requirements to run their business and it is continually influenced by many different things. Do they already have a large IT investment? Do their IT requirements expand and contract depending on current activities? Do they have a diverse investment and skills on existing service management tools? It's apparent that these same questions can be asked regardless of the size of your IT shop - big or small companies have come to depend on IT services and this dependency continues to grow in this computing revolution. One direction an IT manager might take is a hybrid approach. Such a strategy allows them to utilize their current investment of infrastructure, tools and skills to build out their own Private Cloud while keeping a Public Cloud vendor accessible when their computing needs spike. Companies have options that they can ponder over to figure out what is best for their company's business, their IT environments and their utility usage.
Most companies have already made large investments in both infrastructure and tools, as well as the skills to maintain them. The need to deliver more with what is available, requires technology that can bridge from existing environments to new environments regardless of the influences. By adopting and adhering to computing standards, tooling can utilize data from existing systems while meeting the needs and different delivery methodologies of the business in new ways. This means I can ease the coordination of complex tasks and workflows in my data center while leveraging the existing skills, processes and technology artifacts to deliver services in new, different ways. By employing computing standards in my data center strategy, I can be assured that I can rely on Public Cloud for my processing spikes; I can utilize both my older infrastructure while integrating in new infrastructure; all with the same extensible tooling for deployment and management of compute, storage and networking. As you're defining the next milestones in your cloud strategy/roadmap, I would encourage you to investigate what is in use today in your data center and how you need to evolve/ reuse that investment.
