Example text

In order to keep the service lightweight, it is also important to adopt a lighter communication method such as REST instead of SOAP. Stateless nature: The less the service contains session information, the more will be its scalability. It is recommended to design the services to be atomic and stateless. If a business transaction spans multiple services then it can be wrapped into a single composite service, or a fac¸ade pattern can be leveraged. Asynchronous invocation: This is more of a guideline for service consumers.

Asynchronous invocation: This is more of a guideline for service consumers. It is recommended to invoke the services asynchronously to avoid page blocking and process blocking. Asynchronous Java and XML (AJAX)-based client-side technologies are for asynchronous service invocation. If the service is REST-based it would be easier and more convenient for service invocation, due to inbuilt support provided by AJAX components. RESTful services: Services should be designed to provide the Representational state transfer (REST) interface because REST architecture simplifies the service invocation and makes the service highly scalable.

Note Normally, hardware and software faults are caused by underlying design and maintenance issues, and the faults occur mainly at runtime. They are difficult to predict as compared to typical exception scenarios. Software fault tolerance Software faults are due to various reasons. A few critical failure scenarios are given below: ● ● ● The application module fails to scale during a heavy load. It could consume high CPU and memory and could exhaust the entire heap memory at higher workloads The enterprise integration component fails to establish connection with the upstream and may fail The application method was not designed to handle the input data and can cause runtime error.
