Which of these is a part of the Sensing Layer of the IoT Service Oriented Architecture?
a. Service integration
b. Service repository
c. Business logic
d. Data sensing and actuation protocols.
Answers
There are many middleware solutions available for the Internet of Things, which address one or more of the aforementioned issues.
Example, Service-oriented middleware is based on Service Oriented Architectures (SOA), in which we have independent modules that provide services through accessible interfaces.
A service-oriented middleware views resources as service providers.
It abstracts the underlying resources through a set of services that are used by applications.
There is a Service Repository, where services are published by providers.
The consumers can discover services from the repository and then bind with the provider to access the service.
Service-oriented middleware must have runtime support for advertising services by providers and support for discovering and using services by consumers.
Service integration, service repository, and business logic are the parts of the Sensing Layer of the IoT service oriented architecture.
Option: (a)
Explanation:
- In SOA, services are considered to be the basic building blocks. A service can be defined as the self contained software unit which performs the certain task. It comprises of three components namely
- An interface
- A contract
- An implementation
- Service integration services are examples of infrastructure services. Business services include service repository and business logic.
- The data sensing and actuation protocols are not the part of sensing layer in IoT of SOA architecture.
