Cloud

Enterprise Architecture is more important than ever with the increased adoption of Cloud Computing.  Most companies that I work with have a range of systems and initiatives that span the continuum of “must stay in house” to “this is best run in the public cloud.”  There are 3 types of Cloud Models:

  1. Private Cloud (we like cloud, but need to manage it ourselves because of security/cost/agility/etc.. reasons)
  2. Public Cloud (here are the systems we need, we will pay you to run it for us)
  3. Hybrid Cloud (some systems we need to keep in-house but for other stuff it would be cost effective (or cost avoiding)  if we did not have to run/maintain them ourselves)

In all cases, Cloud is an IT operational model (what systems run where) that is driven by business needs and imperatives.  Even if you go 100% Public Cloud, you still need to make sure that the Applications and Information provided by those systems are meeting the ever changing business needs.  The Hybrid Cloud model provides even more complexity because applications, communication, integration, data flow, and security need to be coordinated across the Cloud boundaries. 

Enterprise Architecture is the glue that can help keep all of these things together and is why Cloud Computing does not get rid of the need for EA, in fact, it is this humble author’s opinion that it dramatically increases the need of EA stewardship over Cloud.

Cloud Decisions

• Evolution rather than replacement.

The private cloud can evolve from existing virtualized infrastructure, enabling the transition to cloud computing without a complete and disruptive infrastructure overhaul.

• Security and compliance.

With a private cloud, data is retained within the enterprise, behind the corporate firewall, where IT can exercise full control over security, privacy, and regulatory compliance. With public clouds, enterprise data is housed in external data centers—and may move from location to location, without IT’s knowledge or consent. The dynamic movement of data in a public cloud may also present compliance challenges with local regulations.

• Service level agreements (SLAs).

Keeping applications in-house can help IT continue to meet SLAs deining performance, availability, and other critical business requirements. Some external providers may not be able to furnish the same level of service.

• Cost.

A large enterprise private cloud can provide economies of scale, resulting in total cost of ownership (TCO) that is competitive with or lower than public clouds. Intel IT, for example, found that services can be hosted internally at equal or lower TCO than hosting them externally.

• Building expertise.

Architecting a private cloud enables IT organizations to develop a knowledge base that can be applied to public clouds in the future. When creating the private cloud, IT will need to develop detailed application and data inventories, and gain key skills such as managing cloud SLAs. This experience will help build effective relationships with public cloud providers, enabling IT organizations to assess whether they meet enterprise requirements
