Transcripts

Hi There, Welcome to this new tutorial.

In this tutorial we will learn all about Azure DevOps,

so basically this is going to be a complete tutorial of the Azure DevOps.

and everything we will learn from scratch.

so, If you are completely beginner to Azure DevOps or you are experienced to Azure DevOps.

then you can watch the tutorial and you will learn lots of things

I will say most of the things of the Azure DevOps through this tutorial.

This is the first part of this tutorial

and in this part we will learn- What is DevOps in general?

We will not talk about Azure DevOps.

I will simply talk about- What is DevOps?

Let's start, First of all let's have a look-

What is the agenda of this video?

In this video we will learn- What is DevOps ?

What is the need of DevOps ?

Who should learn DevOps?

What are the benefits of learning DevOps?

These few important questions we are going to cover in this video

before DevOps let's have a look on how software development works?

So basically I will be discussing a basic life

cycle of the software development.

In the starting of everything you have to a make a plan.

once your plan is ready you have to write the code,

once you are done with the code

then you have build your code

so that you can give it to the testing team.

Then the testing team will test the product.

after that it will be deployed on the server .

Once the code is deployed on the server

there are the some operations which needs to be perform.

The last one is monitor.

someone from the team has to monitor.

what exactly is happening on the server?

Does it need the scale up or the scale down

or do need to increase the server capacity etc.

all these things we need to monitor on server.

so, if you are working in startup company.

or you have a very small premises or you have very

few number of peoples in your team.

Then all these things are done by the same team.

The same team will work on the plan,

the development the also on the deployment.

But if you are working in a big organization

or even if you are working in a small organization

and still your organization follows some process.

Then things are little bit differ.

How? all these steps are done by different teams.

So, first he have the plan for the planning

of the any project we have a different team.

We can say this team comes under

business team or the product owner.

The product owner sits with the client

and he work on planning part of the product.

Then we have the development team,

development team includes developers and the testers.

They code build and test the product

and then at the last we have the operations team.

The main work of the operations team is the deployed

the code on the server, monitor it and operate it.

So, right now we can say that we have three teams

working on a particular product development .

Earlier when we were working in the waterfall model

then all these teams were working independently.

When agile came in to picture the gap in between these two teams were filled.

or business team or PO and the development team were working

together on the success of a product.

Now we have one more team it is operations team.

Still there was a gap in between these two teams.

The development team and the operations team.

Now let's understand, what is DevOps?

DevOps is something where the developments

and the operations work together.

So, we have the Dev from the development

and Ops from the operations .

Hence we have a new word which is DevOps.

So, from this slide you will understand that DevOps is something

related to the development team and the operations team.

And there is a plus symbol in between them.it means they will work together.

Basically DevOps fills the gap in between the development and the operations.

Just like Agile did to the business team the PO and the development team.

same thing is done by the DevOps for the development and the operation .

Let's have a look on few points of , What is DevOps?

DevOps is a culture or practice. Okay,

This is very important to understand.

"DevOps is culture or practice".

Which fills the gap between development team and operations team.

If you are thinking DevOps is a tool, a process or methodology.

Or any technique then this is not true. DevOps is basically a culture.

It is a practice. both the team works together in entire software development

life cycle to ensure the quality of the product.

ability of the product to work in different environments.

Let me tell you a very general statement from the development team.

So, what happens when a particular developer develop something.

and he gives it to tester for the testing.

and if something is not working in that environment.

then there is a general excuse or we can say general

statement for the development team.

that this is working fine on my system.

I do not know, what is happening on the other environment ?

It means there is some problem related to the environment.

and this gap is filled by the DevOps.

DevOps environment both the teams work together.

and they focus on the environment.

the quality of the product and there are different

aspects that we will learn in the later part of this video.

or in this tutorial all these points are taken care

by the DevOps. lots of tools are available in market.

to automate this process, to work in the DevOps.

there are multiple tools are available in the market.

you can choose anyone of them.as per your requirement.

all tools have their on configuration ,

their on price , some of them are free, some of them are paid.

but all of them have a feature to automate your process.

ultimately all these things happen in a automatic way.

DevOps help us to run the life cycle on each commit.

or particular interval by using automate process .

What is the meaning of this line?

if you talk about the overview of the software development life cycle.

what happens initial we plan, we develop and we deploy .

but if I say all these process

will happen on each commit you made to your code.

so, whenever you are working on a git repository

or any other code repository and you commit your code

and you simply push it. all the steps happens there automatically.

so whenever you push the code it will build automatically,

it will test automatically, it will deploy automatically

and other operations which are available there

all those operations will happen automatically.

so, basically we are taking care of each commit

of the software development to ensure the quality

and other aspects of the product that was all about the introduction

to DevOps now the question is- Who should learn DevOps?

this is very important question

Who should learn DevOps?

each person who is working in a software development team

Developer, tester, product owner, scrum master etc.

all the members who are working in the development

team needs to learn DevOps

I am not mentioning any technology.

so, if you are working on any technology

then you should learn DevOps

DevOps is irrespective of your technology

if you are working with .net or java

or php or angular or any other technology

which is available in the market

then DevOps is for you

operations team obviously the operations team

all the members from the operations team

who are responsible for the deployment, the management,

the monitoring all those things, all the persons from the operations team

must learn about the DevOps

Individual developers- if you are not working in a team

and you are individual contributor on a particular project.

Still you need to learn about the DevOps.

because it is going to improve your process.

your speed of development,

your speed of deployment,

all these things it is going to improve a lot

Freelancers - so if you are a freelancer

and you need to manage your code

so , sometimes what happens you write your code into your system.

and because of some reasons that system got crash

then what will happen?

you will lose all your code, all your planning

everything will be lost

what will happen if you will manage

all these things on a particular server

then everything will be available to you

every time whenever you will access

that server from any kind of machine

Management- the management team is must also

learn about the DevOps because what is exactly

is the development team is doing

they can get a clear picture by looking at few graphs

and the details of the work which is going on

hence management team should also learn DevOps.

The Client- if you are the client of a product

and some team is working on your product

then you must learn about the DevOps.

because you can get a clear picture

of what is going on in the development

you can see the progress with the help of

multiple type of graphs. with the help of deployment

how many bugs are there? how many stories are there?

etc. these points are taken care by the DevOps.

so, if you are a client, he must learn about the DevOps.

and the last everyone who is related to the development

of something in any way.

if you are developing something and you have any connection

to that development then you must learn about the DevOps

Let see what are the benefits of DevOps?

fast delivery- deploying code from Dev machine to server is very fast

so, basically developer has to commit the code

he has to push into the particular repository

and all the process of deploying in the code

will be automatically. so, it is very fast deploy

on the particular server

Reduce time- lots of things (Like testing, deployment, rollback) are happening automatically.

obviously, in the beginning, you have to make some setups

we have to write some code

but once you are done with all those things

and everything will happen automatically

like the testing , the deployment all you have to

all you have to do is you have to focus

on the development you have to push your code

and rest will be taken care by the DevOps.

Rollback- any release which you think should

not go to end user(because of any reason,)

you can roll it back easily.

so, what happens you have push the code and

which has the feature that you do not

want to expose to the customer

simply you can roll it back very easily

if you talk about the another scenario

sometimes a wrong feature it checked in

and that is deploy on the server

still in this scenario also you can roll back your code very easily

Quality- with lots of automatic tools we can get check

the quality of code before deploying it on server

so, there are several steps you can apply the manual testing

or the automatic testing all these steps can be

taken care by the DevOps and you can

ensure that the quality work is going on the server

if there is some problem then you will

get to know that this is a problem

you can fix it and again

you can push your code and you can again run the

entire process to make the successful deployment

Collaboration- all teams works together to build a great product.

so, whether you are coming from the management

background or you are coming from the development team

or you are coming from the operation team

all the teams work together in order to build a great product.

More Agility- every commit is treated as final delivery.

so, if you talk about the Agile process

in the Agile what happen?

we have to work in the sprints

and at the last of the sprint

you have to gave something valuable product

to the customer and what is meaning of the valuable

it should be well developed , it should be well tested.

well deployed all the things

should be there in that code

now if you break it down into very small

part and we say that all these steps will be taken

care whenever you will make single commit

that's why we say more agility

means it brings more agility to the development

Easy to use - DevOps is very easy to use

you can learn it very fast it is very simple to use

No maintenance- there is no maintenance cost

if you are working with the DevOps

Reliable - you can trust on the DevOps

that you will always get the quality of product

and the quality services from the DevOps.

Secure- security is something which is the main concern

we can say DevOps is completely secure

but it depends on the tools which you are using

for the DevOps . since in this entire tutorial

we will work on the Azure DevOps

we can say that Azure DevOps is 100% secure.

there is a guarantee of the security

there is no doubt in the security of the process

of everything.

and there are lots of benefits of the DevOps

which we will learn whenever we will work on the DevOps.
