In theearly year of software
development when it was just
coming up, waterfall modelwas
used.
Waterfall model isa verystandard
model usedinmany different fields,
not just software development.
Itwasveryuseful whenthe
requirements were concrete andthe
developmentcycleswere long.

16. Version Control -GIT

17. What is Version Control?

18. These days when softwareisdeveloped,Itis not developed withthemind-set
that there will only be one pieceofcode that will be deployed andthat’sit.
These days smaller snippets of codearedeployed in regularsuccessionswith
regular feedbacks.This leadstomany different versions ofthecode.
Andthat createsaneedtoorganisethecode and all ofitsdifferentversionof
it.This is where Version Controlcomesin.Itisa practiceof managing and
storing differentversionofa sourcecode.
This is especiallythecasewith Larger companies that have multiple projects
and multiple teams working within it.

38. What is Docker?

39. What is Docker ?
Docker is a tool that helps in developing, building, deploying and executing software in
isolation. It does so by creating containers that completely wrap a software.
The Isolation provided by container gives a layer of security to the
containers.
