Adoption of SOA and services will not make applications obsolete as services will most likely be packaged into applications and not all applications will adopt SOA.

Services- whether lines of business, departments or at the enterprise level- will at certain adoption stages or maturity levels both adopt and leverage the SOA architectural styles and technologies. Some services will be used at the enterprise levels while others may be limited to particular business units.

Such adoption does not mean the services used only in a business unit cannot easily be expanded to the enterprise level. Does it mean that you are equating SOA with technologies that are used for its implementation?

Is a set of technologies really crucial for defining SOA? We emphasize five differences: standards, extensible markup language, means of accessing databases, contracts versus interfaces and services as business assets, as distinct differences between SOA and prior approaches such as CORBA and DCE.

At the same time when we discussed standards, the bulk of the standards we illustrated are focused on Web services that may have diluted the message that there are five distinct differences.

Should in reality this be SOA vs. You seem to come to the conclusion that resource is equivalent to service. Can you elaborate on this one? Applications are a combination of things that might be resources and services or events. ROA was coined by a single person and we can trace its history, but since SOA has a more fuzzy history, its multiple definitions abound. We are not equating a resource in ROA as services. ROA is largely for read-only data. Yes, SOI exposes existing application functionality as a service interface.

However, SOI could also be described or defined as adoption of an ESB which promotes accessing, routing or transformation for business aligned services. Do we define SOI in terms of patterns? Do we expand the definition to the realization of those patterns? InfoQ : When defining information services you seem to imply that those are the ones providing CRUD interface to the data. How can you bring these two together? The author goes on to describe how to mitigate the risk and issues but the solution still uses CRUD.

NET solution. In Chapter 8, Information, Question 74, we describe how information services can be classified. One of those classifications can be a data service that is largely implementations of CRUD. Of course if it is a service, it must adhere to the attributes of a service that we describe in Chapter 1, SOA Basics, Question 3. This is true regardless of how we classify the service.

So by understanding and implementing a SOA service as described in Chapter 1, one avoids the consequences defined in the referenced article. In addition, in Chapter 8, Information, Question 77, we describe scenarios where it might make sense to create a data services that is CRUDy. InfoQ : In your book you seem to imply that registry and repository are the same thing, although in reality they solve separate sets of problems. Do you consider implementing them as a single entity a best SOA practice?

Kerrie and Ali : In Chapter 9, Infrastructure, Question 83, we identify and define the building blocks of an SOA infrastructure which includes a registry. We specifically don't identify a repository because repositories are used for a wide range of concerns beyond SOA and we don't see a repository as a unique building block of SOA; although repositories may be required to make the SOA infrastructure operational just like integrated development environments IDEs may be necessary to realize services.

So registry and repositories are not the same thing, and we agree they solve separate sets of problems. In answering Question 87, as to how the ESB and registry relate, we provided an illustration showing the life cycle of using a registry where a repository would also be used to facilitate discovery of service endpoints.

Life cycles for governance, security or registries, for example, will need to house metadata to manage the life cycle and a repository is just such a choice. Vendor technologies which have a registry and repository as a single entity can offer advantages in optimizing governance and management. Ali Arsanjani, published Nov.

SOA permits businesses to arrive those pursuits via tightly aligning the company and IT round the enterprise methods, breaking these procedures into reusable company and IT prone, and permitting the underlying enterprise and IT infrastructure to be extra nimble in assisting the company targets.
