What is DevOps? Basics of DevOps You Should Know

Change is inevitable. Business trends today are the successful fruits of changes in software development models. DevOps. Yes, DevOps has a significant role in the progress and enhancement of software development and deliveries across various platforms.

With the accelerating buzz of this new culture, it has become mandatory for many professionals to inculcate DevOps skills – DevOps training enables people to learn about the DevOps phenomenon and technologies. However, here is a short note to know what it is and its simple basics.

Earlier, software development and its deployment were carried out independently by developers and operators respectively. There was no interaction between the development, testing, and operating teams. As a result, many issues arose upon deployment and delivery to the production environment. Again, the development and testing teams had to work on it – a waste of resources, time, and intellectual means.

If there had been a healthy cooperative environment between them, then the unnecessary errors and negative feedbacks could be stopped. Traditional waterfall and agile models are effective only to a little extent – but there were certain problems. So, there was a need for the invention of a new software development model that enables faster deliveries without errors and hassles.

Here came up the DevOps.

DevOps – What it is?

DevOps is a new trend of culture, philosophy, practice, and tools intended for businesses to quickly deliver the applications and services. The infrastructure and management processes of the businesses are enhanced with DevOps. So, the enterprises will be able to easily market their services effectively with utmost customer satisfaction.

DevOps is a combination of two words or teams or processes - ‘Development’ and ‘Operations’.

It is a culture where the developers and operators work collaboratively with extensive DevOps principles and workflow. It includes distinctive processes, tools, and technologies that are used at a suitable time with appropriate accuracy and timely phase. It is intended to help businesses a lot.

Let’s know its significance.

Importance of DevOps

DevOps has become prominent for business use because, it –

·         Improves the frequency of deployment

·         Enables faster deliveries to market

·         Reduces the failure rates of the new releases

·         Minimizes the lead time between error fixation

·         Improves the meantime for recoveries

·         Includes effortless processes for recoveries

·         Improves the quality of application development

·         Stabilizes and secures the operational state of the software system

DevOps is the perfect technological state that can be used for larger complicated applications like eCommerce sites. It is also suitable for applications hosted on a cloud platform.

As you got to know about the importance of DevOps in businesses, now, understand what DevOps includes.

DevOps Lifecycle

Lifecycle is a sequence of phases – DevOps lifecycle is the successive phases of activities in the software delivery pipeline. Different processes of software development till delivery are carried out continuously in DevOps. Its lifecycle includes different phases –

1. Continuous Development – Development of software happens in this phase with sorter sprint development cycles. This increases the speed of the development and delivery process. Also, it reduces the stress for developers.

2. Continuous Testing – It continuously focuses on testing the codes and fixes the bugs. Testing or QA teams use specific automated tools like Selenium to test the software over and over.

3. Continuous Integration – In this phase, the new delivery code is integrated into the prevailing one. Appropriate integration and sync are checked simultaneously. If the right integration is not evident, then the development team will work again on it.

4. Continuous Deployment – A continuous deployment phase in DevOps is processed. Sometimes, certain changes are made in the code and these adjustments should not affect the function of the application or service. Also, it should not affect the high traffic website.

5. Continuous Monitoring – During production, sometimes, errors may occur and to bug this, one should monitor them continuously. This ensures better availability of the applications.

The definite flow of these phases ensure efficient faster results. This happens with an appropriate workflow.

DevOps Workflow

The word workflow denotes the flow of work processes. DevOps workflow includes continuous processes of all the phases. They also enable a definite ideal process for job configuration.

In DevOps workflow, the development and testing phases happen in a parallel way. Based on the requirements and situations, the workflow will be varied. However, there is always a collaboration between the developers, testers, and the operators – it is the characteristic of DevOps workflow.

Whatever the process may be, the activities through DevOps are performed with the help of certain software programming codes which are considered DevOps tools.

DevOps Tools

DevOps tools are nothing but simple codes that are used in software development. There are many DevOps tools which are essentially important. They are – GIT, JENKINS, Selenium, Docker, Puppet, Chef, Ansible, Nagios, Splunk, and ELK Stack. They enable configuration management, deployment automation, log management, monitoring.

One who has very good proficiency in thesetools can have an excellent career in the DevOps field. Whether a developer, operator, or a testing professional can learn them and attain very good jobs. There are many professional roles in this field – DevOps Evangelist, Release Manager, Automation Expert, Software Developer, Software Tester, Quality Assurance, DevOps Engineer, and Security Engineer.
