Question

Charlie has just learned about web services architecture and is convinced that it is the best thing since sliced bread! Even better, he has just found out that Amazon offers a set of its web services for developers to use. He just can't wait to tell Suzanne about this.

Visit : https://aws.amazon.com/

or find a similar web services provider to learn about web services that are provided to developers.

Then, answer the following questions.

• Explain why you would or would not consider developing an application based on these web services.
• Do you agree with Charlie that web services architecture is an amazing technology and should definitely be used in a project? Justify your response.

Answer 1

Positives:

Interoperability between Different Applications: Web Services permits various applications to communicate with each other and share data, services(logic).Ex. Java and .Net applications can communicate with each other using web services.

Common Protocol: No need to define the various methods and interfaces jas they have the common protocol.

communication: Basically web services use the HTTP protocol to transfer data from one system to another decreasing the cost of transferring and overloading of network.

Dependency: Less dependency as they are self-describing and URI(Uniform resource interface) gives the full information of the endpoints leading to less resource utilizing.

Deployability: Can be deployed easily and SSL implementation is easily configured on it.

loose coupling: Helps to design modules independently.

Negatives:

HTTP is a stateless protocol and this is a hindrance in maintaining the long sessions.
