Removing a file from git staging (index) area.

Assume git add sample file => for adding the file to git staging area.

Check the git status command

Use git rm for removing the content from working tree and index of the repository.
Examples are,

git rm --cached sample file

The command given above will remove the file from staging area but still available in working copy.

git rm -f sample file

The above command will remove the file from working copy as well as from staging area.

Note:
Unless the file is added to the staging area, git rm command won’t execute on that file.

In today's DevOps related study, people are focusing more on continuous integration, continuous delivery, continuous deployment, continuous build etc. These are all processes and procedures before releasing the software into production. However, what people tend to forget is that there are devops activities even after the deployment of application in production.

Continuous Monitoring is one such major process. Once the application is deployed into production, then a monitoring has to be set up to have the application monitored under policy based application monitoring. The monitoring setup should be automated. And the monitoring should focus into finding areas of problem within the software proactively. The idea is to find all software bugs before they start affecting the actual operations. The proactive monitoring should help in finding potential bugs before users can start facing problems due to the bugs.

Example wise, you can think of a video chat application being launched. It may happen that during all kinds of testing the application succeeded and proceeded towards launch into production. However after being launched in production it is found that when multiple people join into the video chat there is a significant cpu spike in the server. While it is not impacting immediately, you know that after a while when the utilization peaks, it will start impacting video chat quality. However, you also understand that such situation will only happen only after more than 20 people join in the video chat. Which is not going to happen just now but may happen in future. Now that you have identified the potential issue in prior, you can alert your developers to fix the code which is causing the cpu utilization to spike. 

This continuous monitoring feedback is an important part of today's devops. Whenever a new application is launched, if it is put under monitoring everytime, then that process is called continuous monitoring

1. What is Continuous Integration ?

Continuous Integration (CI) is a development practice that requires developers to integrate code into a shared repository several times a day. Each check-in is then verified by an automated build, allowing teams to detect problems early.

By integrating regularly, you can detect errors quickly, and locate them more easily.

2. What is Continuous Deployment ?

Continuous deployment can be thought of as an extension of continuous integration, aiming at minimizing lead time, the time elapsed between development writing one new line of code and this new code being used by live users, in production.

To achieve continuous deployment, the team relies on infrastructure that automates and instruments the various steps leading up to deployment, so that after each integration successfully meeting these release criteria, the live application is updated with new code.

Instrumentation is needed to ensure that any suggestion of lowered quality results in aborting the deployment process, or rolling back the new features, and triggers human intervention.

Definition of DevOps

DevOps is a new term emerging from the collision of two major related trends. The first was also called “agile system administration” or “agile operations”; it sprang from applying newer Agile and Lean approaches to operations work.  The second is a much expanded understanding of the value of collaboration between development and operations staff throughout all stages of the development lifecycle when creating and operating a service, and how important operations has become in our increasingly service-oriented world.

If you studied maths in 11th and 12th,get into data science/business analytics/data analytics/bigdata analytics.Above mentioned are one and the same.Why am I suggesting above are following reasons. 1)Data science require knowledge mathematics like Matrices/Calculus etc.These are the concepts which you have learned during 11th and 12th.So you have better advantage over others who have not studied maths at 11th and 12th.(It does not mean that others can not learn).2)When you have maths background,you have upper hand on other folks with non-maths.3)Other technologies like hadoop/devops can be learned by anyone irrespective of their qualification.3)The job market and salaries are very high for data scientist .Hence if you want to dofferentiate from others,you can go for data science which is beautiful subject.For any help,you can reach out to us. read less
