Welcome to your Node.js project on Cloud9 IDE!

This chat example showcases how to use socket.io with a static express server.

Running the server

1. Open server.js and start the app by clicking on the "Run" button in the top menu.

2. Alternatively you can launch the app from the Terminal:

   $ node server.js

Once the server is running, open the project in the shape of 'https://projectname-username.c9.io/'. As you enter your name, watch the Users list (on the left) update. Once you press Enter or Send, the message is shared with all connected clients.

Developing

ARCHITECTURE:

We are developing a Multitenant SaaS Application which will feature the three SaaS Applications. This is a multitenant model where the user has the option of selecting and working with any of the three SaaS applications: Waterfall, Scrum and Kanban. The UI designed in AngularJS captures the features of these systems. This application has a primitive login/Registration page where the user can login or can register as a new user and then gets a Preference page to choose or edit any of the three Waterfall, Scrum or Kanban. After setting the preference he can later view the project status. Project status again comes as relative to the tenant’s selection of the SDLC method. Our’s is a multiple page approach, there’s a Project Page that displays a list of Activities (i.e Task ,Story, Card etc.). There’s also Activity Page from where the Activities can be approached and edited. Same code base renders all the three tenant types. Waterfall models are design processes used for developing software models. It renders a linear sequential life-cycle. It undergoes a number of phase conversions systematically in a downward fashion catering to the shape of a waterfall. The important phases involved: Requirements, Design, Implementation, Verification and Maintenance. Scrum is an agile methodology used for project management. It’s a process adopted by the teams to coordinate and work collectively to deliver a product . The development process occurs in small pieces and the current level pieces are constructed depending on the previous work. This makes testing and modifications easier because it’s conducted on modular pieces. It simplifies the process of creating projects with rapidly changing requirements. Kanban is a systematic approach used for maintaining and improving the level of production. It manages the software development process in an efficient fashion by providing faster outputs, flexible planning options and transparency through the lifecycle process. Now coming to our project the UI page provides the user with an option to sign up for the application. After he signs up for the application he gets a preference page where he will be able to set up his choice for either of the Saas applications. The design is such that it will automatically render the data elements and schemas based on the user’s selection.

###Technology Stack:

1. Node.js: The javascript server side technology which is highly efficient for highly resource intensive web applications is chosen for coding the business tier.

2. Angular.js: A powerful javascript binding framework based on MVC, works well with server side components working with JSON (Node.js in this case).

3. Mongo DB: A No-Sql storage stores data in the BSON format, also faster for consistency and transaction.

4. Redis Cache: A fast in-memory database will be used for object caching in EC2 instance, can also work in distributed mode.
