Course1 Introduction

Cloud Native Apps

Scalable: Run in scalable, sothat we can have more and more users;
Loosely coupled: Our apps is easy to change;
Resilient: The failure can auto recover;
Manageable, observable: We want our apps transparents and want to wander whether apps running well.
Agility: Be able to make high-impact changes frequently and predictably.

How to define a good Apps

Usability: e.g. Test application from the perspective of convenience to end-user.
Reliability: e.g. Test the application behaves consistently and predictably.
Performance: e.g. Test online response under average and peak loading.
Supportability: e.g. Test the ability to maintain and support application under production use.
Functionality: e.g. Test the accurate workings of each usage scenario.

Steps of Software

1. Requirements Analysis
   Requirements from customer, ask what they want, ask the features and so on.

2. Design
   After get the requirements, maybe we need to draw the flow chart to show the logic of the program and so on, to show how do we structure our program and the behavior of the program.

3. Code
   Coding…

4. Intergration
   A team has many programmers, each of them produce a component, then we intergrate them together.

5. Test
   Test with our customers and users, then maybe we need to recoding and reintergration to fit the requirements.

6. Deploy
   After test, we deploy.
