4. The client facing browser and
mobile applications make requests
to servers that are up in the
internet. The servers upon receiving
such requests do computational
actions required and return data
that is consumer and presented to
the customer in a user-friendly way.

7. PRODUCTION
deploying into
Tutorials and framework documentation aids us to build thing
and get it working, on our local machine. How do build for the
billions?
How do we go live? What is production-ready?

8. DEV,STAGING&PROD
— A comparison on environments
A local developer's machine, where the active
development is happening. No end user connects to this
machine. Developers play, break, develop and tamper
with code and data.
DEVENVIRONMENT
A production like environment set-up to simulate real-
world scenarios. Performance testing, stress testing is
done in this environment. The data in this environment
is used for testing purposes only.
STAGING/PRE-PRODENVIRONMENT
Actual environment that holds real world data. Data
loss, downtime can have serious business implications.
Exposed to outer world, security concerns rise.
