Dev Ops Essentials Course

 Why I should know/learn DevOps
 What is new in DevOps or DevOps itself is new?
 Is it a tool or an approach of working or combination of only tools?
 Is it really required or just a myth of companies to create extra
pressure?
 Is it necessary to learn this or work with this? Is it easy to learn or
not? Can I get a good package after learning this? Etc.
 Can I learn it easily?
 Did DevOps helped any companies?
 Is it really changing anything or changed that we know but did not
notice?

 Will see all the details one by one

 Some terms we hear regularly during our work in software market
 Software Development Life Cycle(SDLC)
 Deployment
 Development
 Server(Linux/Unix/Windows etc.)
 Error in production
 Client is giving very less down time(cant work like this)
 Coding , Building , Release
 Success at development side , failure at production site
 Blame keeps on going….

 Software Development Life Cycle (SDLC)
 We know it already… (will see which phase we are working or
searching job )

 We all fall into some part of SDLC.
 What we hear or say or do in our offices or planning to do.
 Project requirement planning (Investigation or Feasibility Study and analysis)
 Task assignment (Design)
 Development (Coding with the language as decided during planning phase)
 VCS/SCM tools (Saving our changes to some remote central server)
 Build , Release (Create a runnable package out of code – Development only)
 Test (Test the functionality – Testing )
 Deployment (Installing our code to run in production server -Implementation)
 Maintenance (After deployment see for error and more requirement change)

 Waterfall Model
 V-Shaped Model
 Evolutionary Prototyping Model
 Spiral Method (SDM)
 Iterative and Incremental Method
 Agile development

 Process of working is mostly synchronous.
 Each process will wait for other process to complete if it’s a waterfall approach. Then
next phase will start.
 Time consuming and cost ineffective process.
 Cleary showing -- lot of waiting time for all the people involved in project
 Now we are thinking agile solved this. Because few year back all said same
thing
 Still there are gap between SDLC phases.
 We as Developer/tester will say, no gap is there. Because agile broke gap between Dev
and QA team.
 But operation (implementation/maintenance) are not in that relational chain
 That’s where companies faced measure business setback from their rivals who broke
that gap with operation team.
 The gap was continuously delivering quality and stable features frequently.

 Development/Testing (Combined phase as collaborated by Agile)
 After Development and testing, the code deployment time is huge.
 Pressure of work on old, pending and new code was high because deployment
time was high.
 Operations (Always a separate entity in SDLC)
 It is difficult to maintain ~100% uptime of the production environment.
 Infrastructure Automation tools are not very affective.
 Number of severs to be monitored keeps on increasing with time and hence the
complexity.
 It is very difficult to provide feedback and diagnose issue in the product.

 Off Course yes..
 DevOps is a way of working which collaborated all phases of SDLC in a
common platform where every process started working in
asynchronous continuous fashion.
 Some tools helped to make this work.
 As per theoretical definition
 DevOps is a practice of operations and development engineers participating
together in the entire software lifecycle, from design through the development
process to production support.

 We used some tools but they were not giving us that flavor of
flexibility because of the SDLC approach we followed.

 Common thoughts
 I am happy with my coding/testing/scripting what ever I am doing?
 Some different team should do DevOps or whatever for me.
 I will only stick to my expertize area.
 I will enhance only that skill.
 That is future.
 DevOps is just a myth.
 DevOps anyway is not affecting what I am doing or what I will be doing

 As we have seen we are part of SDLC, So knowing DevOps model is
coming to our bucket.
 Companies are not going to hire new people for this work. (Cost
involved). Why to hire when existing employees can learn and do.
 If I am not doing then someone else will do. My job and career will
be on dilemma.
 Future of Software development will no more be a separated
process of coding/testing/operating.
 All will be merged and term will be Devops engineer.
 What you are doing, you will do that. But yes need to know all will
be managed in continuous fashion.

 I guess we are clear till now whether it is new or its some older way,
nothing new in it.
 Anyway It’s definitely a new way of working which broke the barrier of ways of
working between all the teams involved in a SDLC.
 We achieved DevOps by help of some tools at each stages of SDLC.
 Some tools we have already used. Some are new.
 We will see how tools helped in this DevOps approach.

 Blue color is part SDLC phases before implementation and
maintenance .
 Orange color is part of operations.

 Do I need to know all?
 No
 From each SDLC phase we will learn only one tool that is mostly used every
where.
 If you are not finding same tool in your company, not to worry.
 That will be mostly same what we will learn in our course.
 We will give overview of most of the tools used in DevOps.

 I am happy what I am doing. Tools won’t help me.
 You are thing it’s difficult to learn. We are here to help you.

 Yes
 Most of the companies are already into DevOps. No worry for job change and
good package
 Who are those companies mostly?
 Facebook
 Amazon
 Netflix
 Walmart
 Nordstrom
 Adobe
 Etc.
 Now you can tell are they all backward or forwarded companies? We
know how much they are paying too.

 You may laugh. But it’s true
 Pokémon Go (Best example of DevOps implementation)
 Tools helped Pokémon Go are

 Will it be easy for me to learn all this?
 Yes, our course is designed so simple that you will enjoy each days learning.
 We will teach you in details of DevOps approaches at each phase of SDLC.
 We will teach you most popular tools from each phase of DevOps which will help you
to crack any DevOps interview and work better.
 How can I practice what I am learning?
 Will show you the local system setup. You can practice same. If any doubt, we will
clarify that.
 Is there any help for interview preparation?
 Yes, We will provide you questions/answers for DevOps.
 We will have mock test by end of our DevOps essential course.
 Will help you to create resume with DevOps technologies.
 Will help you to build your LinkedIn job profile..
