Assignment Task: It consists of a demo code package and a technical report for the integration plan.
Case Study: easyJet - Technology Strategy
There are 2 parts to this Assignment:
Part 1: Integration Demo:
easyJet have been looking for ways to help passengers to plan their journeys. Your Integration Demo will demonstrate a basic passenger journey planning microservice using service-oriented architecture. You will use a Google Maps Mashup to plot a passenger journey (including a number of 'stop-overs'). Your Google Maps Mashup will capture the endpoint coordinates (along with the name the passenger chooses for their journey) and send them to your microservice for storage. You will also be able to recall a stored passenger journey from your microservice and replot it on your Google Map Mashup. Please follow the instructions carefully. There are two major components in the demo system:
1. Microservice server demo. In this demo, you are required to build a RESTful Web service which supports two services:
'saveJourney' query from the client browser similar to
'/saveJourney?journey=[xml object]'. This server Web Service will accept an XML object with similar format to Figure 1. As part of the python service you are required to:
i. accept the XML object and extract the journey name which will become an xml file name (e.g. 'Journey 1.xml'),
ii. Store the journey information in an .xml file using the Journey name as the file name.
'getJourney' query from the client browser similar to
'/getJourney?jouney=[journey name]' will retrieve the passenger journey information from the server:
i. The journey name will be accepted, and the corresponding xml file will be retrieved and returned as an XML object to the Google Maps Mashup.
The Python Bottle framework is required for this implementation. A Python scrip file with the name 'microservice.py' will contain this RESTful Microservice Demo.
2. Mashup demo. In this demo, you are required to build a html Google Maps Mashup application which accepts a journey name as the input. There three functions (buttons on the html page) are required after the html page is initiated with a raw map:
Function 1: Clicking on the Map will create markers and polylines between markers as you continue selecting locations. These polylines between markers will simulate a passenger journey for which you will input a name, collect the coordinates and their order into an XML object, and send to your microservice via your AJAX web service.
Function 2: You will need to be able to clear the map back to its raw newly initiated state.
Function 3: You will be able to type a journey name into the input and retrieve a passenger journey from your microservice and populate the map with the saved journey:
i. This function will retrieve an XML object from your microservice via another AJAX web service.
ii. Once your AJAX service receives the object it will need to extract the individual latitude and Longitude coordinates from the XML object and push them into the MVCArray.
A HTML file 'plan_journey_map.html' should be implemented. In this file, a text field is provided at the page top to accept passenger's route name input. In addition, three buttons are required to implement the three functions.
Part 2: Integration Report
In addition to the above Demo code (40%) you are required to include a Report (60%) Based on the above case study explaining the key concepts for:
- The demo design and implementation (including instructions on running your code).
- Information Management and Integration.
- Application and Data Storage Infrastructure design, and
- Application and Service Integration.
Please use the following outline in your report:
1. Introduction
2. Information Management and Integration - Discuss and design strategies to integrate the multiple data sources developed and used by different teams for various business units and departments.
3. Application and Data Storage Infrastructure Design - Discuss various cloud options and their suitability. Design a cloud infrastructure strategy.
4. Application and Service Integration - There are many different types of applications and services coexisting in easyJet, including legacy applications, internal Web services, and external Web services. Some external services are provided by business partners and others are from public service providers such as Google Map and Google Search. Discuss and design service and application integration strategies.
5. RESTful Web services - Explain RESTful Web services and how they were applied in your Demo
6. Mashups - Explain Mashup principles and how it was applied in your Demo.
