What is an environment?

26. Stanford Graduate School of Business
What is an environment?
=> The system in which an application is executed

27. Stanford Graduate School of Business
3 Types of Environments
Development Staging Production

28. Stanford Graduate School of Business
3 Types of Environments
Development Staging Production
- Live version of your
application
- What your customers
interact with
- Replica of production
environment
- Used for testing bugs
- Also known as “local”
or “dev”
- Unique to a computer

NOTE: Each environment may have different versions
of an application and its database!

30. Stanford Graduate School of Business
What is version control?

31. Stanford Graduate School of Business
What is version control?
=> A system that records changes made
to your application over time

32. Stanford Graduate School of Business
Version Control
- Git generates a snapshot in time of your entire application
- Saves the history of changes made & who made the change
- Used for all environments (dev, staging, production)

33. Stanford Graduate School of Business
Version Control
Apps
MySQL DB
local
“git push”
repository (cloud)
