Unit III

1. What is Service Oriented Architecture?

Service oriented architecture is essentially a collection of services. These services communicate with each other. The communication can involve either simple data passing or it could involve two or more services coordinating some activity.

2. Define Contemporary SOA.

Contemporary SOA represents an architecture that promotes service orientation through the use of web services. Contemporary SOA represents an open, agile, extensible, federated, composable architecture comprised of autonomous, QoS-capable, vendor diverse, interoperable, discoverable, and potentially reusable services, implemented as Web services.

3. List out some characteristics of Contemporary SOA.

Some of the characteristics of contemporary SOA are:-

i. Contemporary SOA is at the core of the service oriented platform.

ii. Contemporary SOA increases quality of service.

iii. Contemporary SOA is fundamentally autonomous.

iv. Contemporary SOA is based on open standards.

v. Contemporary SOA supports vendor diversity.

vi. Contemporary SOA fosters intrinsic interoperability.

vii. Contemporary SOA promotes discovery.

viii. Contemporary SOA promotes federation.

ix. Contemporary SOA promotes architectural composability.

x. Contemporary SOA fosters inherent reusability.

4. What are the benefits of SOA?

The benefits of SOA are:

i. Improved integration and intrinsic interoperability

ii. Inherent reuse

iii. Streamlined architectures and solutions

iv. Leveraging the legacy investment

v. Establishing standardized XML data representation

vi. Focused investment on communications infrastructure

vii. “Best-of-breed” alternatives

viii. Organizational agility

5. What are the common pitfalls of adopting SOA?

The common pitfalls of adopting SOA are:

i. Building service oriented architectures like traditional distributed architectures

ii. Not standardizing SOA

iii. Not creating a transition plan

iv. Not starting with an XML foundation architecture

v. Not understanding SOA performance requirements

vi. Not understanding web services security

vii. Not keeping in touch with product platforms and standards development

6. What are the requirements is needed to fill QoS gaps between contemporary and Primitive SOA?

Contemporary SOA is striving to fill the QoS gaps of the primitive SOA model with the following requirements:

i. Security (contents and access)

ii. Reliability (message guaranteed delivery)

iii. Appropriate performance

iv. Protecting business integrity

v. Executing exception logic in case of failure

7. What is Autonomous Principle?

Autonomous Principle represents the ability of a service to carry out its logic independently of outside influences.

8. List out the different levels of Autonomy.

Different levels of Autonomy are:

i. Runtime autonomy

ii. Design time autonomy

9. What is Runtime Autonomy?

Runtime Autonomy represents the amount of control a service has over its execution environment at runtime.

10. What is Design time autonomy?

Design time autonomy represents the amount of governance control a service owner has over the service design.
