===============================
Q) What is software project ?
===============================

=> Collection of software programs is called as Software Project.

=> To develop software programs we will use programming languages

	Ex: C, C++, JAVA, Python, PHP, C# .Net..........

==========================================
Q) Why to develop software projects ?
==========================================

=> Software projects are used to reduce human efforts and simplify humans life.

	1) IRCTC for train tickets booking
	2) Netbanking for banking operations
	3) Amazon, Flipkart etc for online shopping
	4) Swiggy, Zomoto
	5) BigBasket, Zepto, Blinkit...

================================
Software Project Architecture	
================================

=> Application architecture contains below 3 layers

	1) Presentation Layer (Frontend)

	2) Business Layer (Backend)

	3) Database (storage)

=> Front end contains user interface (presentation layer)

	Frontend Technologies : Angular / React JS/ Vue JS

=> Backend contains business logic of the application.

	Backend Technologies : Java, Python, .Net, Node JS, PHP...

=> Database is used for storage

	Databases : Oracle, MySQL, SQLServer, PostGres SQL, Mongo DB..


========================
Application Tech Stack	
========================

App-1 : Angular + Java + Oracle

App-2 : React JS + Java + Mongo DB

App-3 : Angular + Python + MySQL

App-4 : React JS + Dot Net + SQL Server

App-5 : React JS + Node JS + Mongo DB


======================
Teams in the project
======================

1) Business Analysis Team (Functional)

2) Development Team

3) Testing Team 

4) Operations Team (DevOps Team)


=> Busines Analysis team is responsible to get requirements from the client.

=> Development Team is responsible for coding (develop the project)

=> Testing team is responsible to verify project is working as expected or not.

=> Operations team is responsible for below activites

	1) Infrastructure setup

		ex: machines, database, storage, network, backup, security...

	2) Configuration Management

		ex: s/w installations, copy files, OS patchings...

	3) Source Code Repos management (Git Hub or BitBucket)

	4) Project Build & Deployment

	5) Infrastructure Monitoring

	6) Application Monitoring

=============================================================================

Infrastructure Setup  ===> Terraform  (AWS + AZURE + GCP)

Configuration Management ===> Ansible

Source Code Repos management ===> Git Hub or BitBucket

Build & Deployment ==> Git + Maven + Sonar + Nexus + Docker + K8S + Jenkins

Monitoring ===> Grafana + Promethues + ELK or Splunk (Logs Monitoring)

===========================================
Skills Required To Become DevOps Engineer
===========================================

1) SDLC

2) Linux OS

3) Cloud Computing (Min 2 clouds)

4) DevOps Tools

5) Scripting (Ex : shell scripting / python scripting)

============================
What is DevOps & Why DevOps
============================

DevOps = Development + Operations

=> DevOps is a culture

=> DevOps is a process

=> DevOps means set of best practices.

=> DevOps is used to establish colloboration between dev team & ops team.

=> The main aim of devops process is used to simplify & automate & speed up application build & deployment process with high quality.

=> We can deliver application to client quickly by following devops practices.

==========================================
How to adopt devops culture in project ?
==========================================

=> By using set of tools we can adopt DevOps culture in our project. Those tools are called as DevOps tools.

**** Infrastructure setup

	Ex: Machines, Database, Security, Storage, Network, Backup etc...

=> Using Terraform we can automate infrastructure setup in project.	

**** Configuration Management

	Ex: install softwares, os updates, transfer files, OS Patchings etc...

=> Using Ansible we can automate configuration management

**** Source Code Management

=> All the developers code should be integrated at once place with tracking.

=> We can use GIT Hub or BitBucket or Git Lab as source code repository servers.

**** Code Review

=> To identify developer mistakes in source code we will perform Code Review.

=> We can use SonarQube to perform project code review.

=> SonarQube is used for static code analysis.

**** Project Build Process

=> Convert project source code into executable format

	 java programs =========> jar or war

	.net programs ==========> dll 

=> We can use Maven or Gradle to build java projects

=> We can use MS Build to build Dot Net projects

=> We can use npm to build Angular or React projects

**** Artifactory Servers

=> To store project build artifacts like jars, wars, dlls

=> We can use Nexus or JFrog to store project artifacts.

**** Application Deployment

=> To run application server is required

	Ex: 
		Tomcat server (java)
		IIS (.net)
		Nginx (angular or react)

**** Automate Build & Deployment (CI CD)

=> Continuous Integration & Continuous Deployment

=> We can use Jenkins to implement CI CD in the project.

**** Monitoring

=> Using Promethues & Grafana we can monitor our servers

=> Using splunk or ELK we can monitor application logs.

======
SDLC 
======

=> SDLC means software development life cycle.

=> SDLC represents the process of software project development from starting to ending.

=> SDLC contains several phases/stages

	1) Requirements Gathering

	2) Requirements Analysis

	3) Design

	4) Development (Coding)

	5) Testing

	6) Deployment

	7) Delivery

	8) Support


=> In SDLC we have several methodologies

	a) Waterfall Model (outdated)
		
		....

	b) Agile Model (trending)

================
Waterfall Model	
================

=> It is linear model / Sequential model

=> Work will be completed step by step

=> After one stage completed then only move to next stage

=> It supports only forward direction

=> Requirements fixed & budget fixed & duration fixed.

=> Client involment is very less.

=> Client will see project only at the end.

=> If client is not happy with project then money will be wasted and time will be wasted.

##### To overcome challenges of waterfall model, industry is using Agile Model now a days #####

==============
Agile Model
==============

=> Agile is an "iterative approach" to develop and deliver software applications to client.

=> In Agile model ( planning + development + testing + deployment + feedback ) is a continuos process.

=> Project functionalitiy will be divided into multiple sprints/releases.

Ex: Client has given 100 requirements

Sprint-1 : 25 Requirements (plan + develop + test + deliver + take feedback)

Sprint-2 : 25 Requirements (plan + develop + test + deliver + take feedback)

Sprint-3 : 25 Requirements (plan + develop + test + deliver + take feedback)

Sprint-4 : 25 Requirements (plan + develop + test + deliver + take feedback)	


=> Client feedback is very important/critical is Agile model.

=> Client involvement is also high in agile model.

=> Requirements & Budget is not fixed in Agile.
