Question

4. Draw a diagram that shows the architecture of the Travel Booking application after the transition to a microservice approach.

Answer 1

Background

Assumption:-

This is an web application, it is an client server model, a user can book tickets from any where across the world. For the success of this application, there should be two versions of this application,

1. One for desktops, laptops
2. Another for mobile phone, and other pocket/hand held devices.

Difference between accessing a web site by a desktop and by a mobile phone.

1. Screen size

In mobile phones, screen is smaller, it means do not put much more text on web site, important information should be easily visible to the user. Web site should be responsive, so that contents can take their place in small screen easily, and provide better visibility to the mobile user.

2. Processing capacity and speed

In mobile phones, processor in less capable as compare to desktop’s processor.

Hence , considering the mobile phones, use less components which requires huge processing.

3. Communication channel Bandwidth

In case of mobile phone, use less images/animations/graphics and other audio/visual effects,

Because they take more time.

For desktop , developer has less constraints as compare to mobile phones.

Micro service approach means, to divide an entire application into numbers of module.

Possible Modules:

1 For User

2 For Administrator

1.User Modules are

a)user registration Module(New User,(Interactive))

b)User authentication Module(User Login,(Interactive))

c)Booking Module(Hotel, ticket booking and so on)(Interactive)

d)Tourism Information(Static Page)

2. Administrator Module

a)To view number of web site visitors(Hits)

b)To display discounts/Rebate schemes on web site

c)To view revenue generated by bookings

d) To view the tourist’s details.

Note:- Web service is a method(function) stored on web server and can be invoked by a computer using internet.

web service uses XML format, because the biggest advantage of XML is that , the result produced in XML can be understood by any computer.
