Who hates success and growth? In today’s dynamic business world, every application and process has been updated and upgraded in order to survive in the competitive field.
Every business must function in rich agility to cope up with rapid changes in the customers’ demand. Across different functions, the organization considers the time needed to market the product and customer’s high expectations as a motivation.
The number of organizations investing in DevOps training has increased. Many companies ought to jump toward DevOps culture to make their progress faster.
Recently, Great Learning report has astonished many companies and recruiters of India. According to the report, India has been expected to have around a million cloud computing job roles by 2022. The reason behind this increase is due to the shifting operation of companies toward cloud infrastructure.
Currently, the Indian cloud computing market has been at $2.2 billion. It is expected to grow around $4 billion in the year 2020. It also leads to the annual growth rate of more than 30%. Further information helps in elaborating the need and the benefits of DevOps.
Where did DevOps start from?
Let us start from the initial stage. Do you know how DevOps have interrupted in the present organizational culture?
It all started with Patrick Debois, a Belgian Software Development consultant. He wants to achieve Nirvana in the field of IT. Meanwhile, he gets frustrated passage toward learning all IT aspects due to the conflicts arose between the developers and system admin. Hence, in order to solve this, he wished to find a solution to build a collaboration between the two teams. After several attempts, he finally organized a conference, DevOps Days. later, it was shortened to DevOps.
Until 2011, the DevOps movement has been sustained by individuals and other open-source tools. But, sooner the DevOps concept has emerged as the dark house. Many research analysts have turned upon toward DevOps and made their ray of opinions about DevOps. Many big vendors including LEGO, Target, etc have started using DevOps in their enterprise.
Pathway of DevOps and its basic process
In the past five years, organizations have changed their way of developing and delivering the software. It is mainly because of the interference of DevOps.
Doing DevOps effectively means the process of integrating effective ways with entities to boost the project delivery of an organization. DevOps, a concept, helps in boosting the software development functions within the same cycle.
Performing DevOps in an organization is not your cup of coffee. Instead, it needs a higher level of coordination among various stakeholders. The stakeholders may also include various departments including Development, Quality Assurance, and Operations. Many hurdles in meeting the clients’ deadlines have been solved using the DevOps concept.
With the DevOps concept, the organizations are finding an amazing way to perform works in an agile manner. It helps in keeping pace with the frequently changing requirements. The working manner involves four basic processes namely,
- Continuous Integration
- Continuous Delivery
- Continuous Testing
- Continuous Monitoring
Continuous integration also known as CI is the combination of source code from different sources and making it into a single application. On the resulting application, a set of automated test cases are run.
CI requires the developers to integrate code. Once the developing team gets its code done, it is necessary to share it in the repository several times a day. Every check-in will be verified and allow the teams to detect the problems earlier in an easy manner.
Through frequent integration, the developers and the operation team can detect errors easily and rectify it sooner.
Why use CI in DevOps?
By implementing Continuous Integration, it will improve the software delivery process. It helps in boosting the development team, QA team, and others. For the development team, they no longer have to worry about the code. QA team focus gets shifted over to the value add work. Instead of just manually executing the cases, DevOps helps the QA team to move further.
The continuous delivery or CD is the process of testing the application in a manner that helps in keeping the product ready for delivery. In short, it is an extension of the CI process that involves enough testing and production-ready scenario.
CD focuses mainly on the process of building, testing, and releasing to the customers in a faster pace.
In addition, continuous delivery helps in releasing the products more frequently and in short cycles.
Benefits of the CD includes the following ones,
- Improves the number of deliveries
- Reduces the failure in production
- Reduces manual work and increases confidence in the team
- Helps the team to automate everything
- Helps in enabling faster feedback
In the continuous testing process, the application validation is built according to the requirements. The continuous testing process helps in testing and bringing quality at every step. The goal of the CT is to test early and test often. By doing so, the errors can be eliminated easily and at initial stages itself. The process involves stakeholders like Devops including Developer and Operational system.
Compared to test automation, continuous testing is the process that neither uses tools nor software. Instead, it is a methodology that helps in achieving continuous quality and improvement. Moreover, there are tools involved during continuous testing. Here is the enlisted variety of continuous testing tools.
The benefits of Continuous testing involves the following factors.
- Helps in boosting up client delivery
- Improves the quality of the code produced
- Helps in assessing exact business risk coverage
- Integrates into the DevOps process easily
- Helps in creating agile and another reliable process in a lesser time instead of months
- Merges traditional teams into modern enterprise ones.
- Builds the connection between the development, testing, and operation teams.
Continuous monitoring helps in analyzing and ensuring whether the application is working under a specified environment. Using the necessary tools, the application’s performance and issues can be detected.
Automating the performance in the continuous monitoring will bring essential benefits. If you successfully implement DevOps culture in an organization, the performance will be monitored without any hurdles.
In the production process, the operation team manages and makes sure about the environment. Using continuous monitoring, the team can check the stability of the environment with the help of the tools. The continuous monitoring will allow both for practical and useful end-to-end monitoring.
With these key aspects, DevOps have interconnected the world with its rapid changeable zone. Along with its benefits, DevOps finds many easy ways to make the processing pipeline smooth.
What DevOps actually brings for a business and the workplace?
Do businesses need to adopt DevOps culture in their workplace? A rather important question ought to be considered. Present tech companies have almost indulged in implementing the DevOps culture in their workplace.
Recent sites state that over 70% of the companies have witnessed improved customer experiences after implementing DevOps culture in their workplace. Many companies including Amazon, Netflix, and Target has been engaged in the DevOps concept to reduce their delivery time and improve customer satisfaction.
According to DevOps.com, the percent of DevOps adoption has increased from 66% to 74% from the year 2015 to 2016, respectively. There are many reasons behind the sudden urge in the percentage. Few picked up and common reasons are enlisted to make you clear about it.
Reducing deployment cycle: expanding innovation pace
When both the operations team and the development team are in separate silos, we can see the communication lag. It is usually difficult for them to tell whether the application is ready or not. Why make it more hectic? Many companies are moving toward DevOps due to their reduced deployment cycles.
When the time spent on processing a particular app reduces, automatically the operation team and the development team may find extra time to think innovative concepts. Thereby, DevOps helps in expanding the mind cover of the employees at a faster pace.
Kevin Murphy from Red Hat estimated that shorter development cycles boost the application to the market 60% faster when compared to the traditional method.
When deployment time reduces, so are the rollbacks and failures
As a joint savior, when a company is quite attentive in reducing the deployment cycles, the rollbacks and the failures are automatically pinned down.
As the DevOps implements shorter deployment cycles, the codes are released at faster rates. It helps in spotting the defect easily. Similarly in rollback, when rarely few modules are affected, it can be identified and solved through frequent code releases.
As the operation team and the development team work together, the time spent on the failures are merely reduced.
Office morale is on the rise!!
DevOps have become new and the best software development culture. As and when the teams are combined, the level of collaboration increases. Thereby, the conflicts and miscommunication regarding the projects can be eliminated.
Moreover, it greatly eliminates the waiting time for the operations’ team. They can involve in troubleshooting and fixing the errors. It becomes increasingly seamless as all the individuals are aware of the problem and help in recovering it as a faster pace.
In another magnificent look, when the process gets delayed, the amount spent on it is also on the hike. By minimizing the processing time, it diagonally reduces the extra amount.
DevOps helps in improving the efficiency
While an enterprise becomes DevOps-friendly, the speed in the development process is foreseen. It also makes both the surviving and future projects less prone to error. Continuous integration servers help in automating the testing code, and thereby reduces the manual work required.
Acceleration tools are another big point in increasing the efficiency of an organization.
- Scalable infrastructures from the acceleration tool increase the team access toward the hardware resources. Hence, the testing and the deployment operation speed up.
- Acceleration tools help in compiling the code more quickly without any time delay
- In order to avoid delay, the parallel workflow has been embedded in the continuous delivery chain. One team waits for another team until their work in the project is done.
- A single environment track can be used for development, deployment, and testing too.
Many companies have experienced these valuable changes in their workplace. Moreover, enterprises have reduced their project delivery time. Companies also believe that through DevOps culture, they are on the right track toward success.
As of now, we have seen the reasons behind the company’s queue up over DevOps culture. But, the question is, do they really find DevOps useful in their enterprise? Let us wrap out the question by doing in detail.
When DevOps is here at the cliff, where is the traditional waterfall model?
Today, we all are talking about the difference between DevOps and Agile models. But, before the advent of these cultures, 7the traditional waterfall method is on the peak. Every company ought to follow the same waterfall model to complete the project.
What is all about? Let me give you a comparison between the traditional waterfall model and the DevOps culture.
Let us assume a project that has to be completed within two weeks. The coding is 80% done. Consider the app as the fresh launch. Hence, the server purchase for the coding has been started.
|Traditional Waterfall method||DevOps|
|Once the order is placed, the development team works on the testing and the operations team works on extensive paperwork required to deploy the infrastructure||In DevOps culture, once the order is placed, both the operations and the testing team work together on the paper setup. As a result, it improves better visibility of the infrastructure requirement.|
|No inputs will be gained from the developers’ side regarding storage requirements, data center locations, and redundancy||In DevOps, the developer has the responsibility of clearing up the inputs regarding all the factors involved including redundancy, projection about failover, etc.|
|In the traditional concept, the operations team has no clue about what is going on in the development team. Since this is the fact, the operations team bring up a plan as per their understanding level about the project.||Here, the operations team has top to bottom information about what the developing team is engaged about. Jointly, both the team develops a plan that caters IT and the other additional business needs.|
|Before going live, the load testing has the chance to crash the application. Hence then, the release will be postponed.||In the load testing process, there will be a minor error. The application gets a bit slow. But, the development team quickly fix those errors without any time lag. Hence, the application will be released on time.|
After getting a clear picture about how DevOps differs from the traditional model, here is furthermore to consider. Few companies may not know when to adopt DevOps. In particular, they are not aware of when not to adopt DevOps. So, which is the right time to enter the DevOps culture?
Here is the answer…
When your enterprise has indulged in the process of handling multiple e-commerce sites, using DevOps is considerable. It is advisable to indulge DevOps when the enterprise involves the applications hosted on a cloud platform.
At the same time, DevOps cannot be implemented in mission-critical applications. It includes bank, power, and other sensitive data sites.
Because those applications need strict access controls over the production environment and detailed management policy. Over that, it needs access control policy to the data centers.
Lifecycle of the DevOps
Without knowing the DevOps lifecycle, understanding DevOps is quite impossible. Let us have a magnifying look at the lifecycle of DevOps.
In the DevOps stage, software development takes place constantly. The entire process will be split up into small development cycles. It speeds up the software development and delivery process.
Testing usually takes place after the development team finishes off its work. Once the code has been tested, the bugs are fixed in the new piece of code. Usually, tools like Selenium are used to test and identify the bugs.
After the new code is deployed, the integration takes place with the prevailing code. Continuous development is possible only through continuous integration and testing.
In this phase, the deployment process takes place to correct up to the changes made. The fact is that the occurring error in the code must not affect the functioning of the high traffic site. Hence, the deployment takes up continuously.
In the monitoring phase, the team eliminates the inappropriate system behavior and the bugs in the production phase.
Workflow involved in DevOps
In DevOps, the workflow has the capacity of owing the sequence of the input. It also gives details about the actions performed and the output generated. Here is the workflow of the DevOps,
Workflow allows the ability to arrange a job according to the user’s priority. In addition, the user can also mirror down the ideal process in the configuration jobs.
Principles involved in DevOps
After DevOps adoption, the organization ought to follow the six principles illustrated below.
- Customer-centric action
- End to end responsibility
- Continuous Improvement
- Automate everything
- Work as one team
- Monitor and test everything
DevOps Engineer is as important as DevOps
Apart from the principle and workflow of the DevOps, the culture can be handled using a DevOps engineer. DevOps engineer is the person who has close contact with the development team.
He/she fulfills the role by solving aback with the hurdles faced during the project progression. DevOps engineer is the one who must have soft skills and hard skills as well.
Roles and responsibilities of the DevOps engineer
DevOps engineer is the role which undertakes the production and ongoing maintenance of the software application’s platform. According to Glassdoor.co, the average salary of the DevOps engineer is around INR 6,34,062.
Here are the common expected roles of DevOps engineer.
- Able to troubleshoot and solve the bugs across the platform and the application domains
- Managing projects effectively in standard-based platforms
- Increase project visibility
- Involve in reducing development cost along with rich collaboration
- Evaluating automation scripts and systems
- Should be a quick learner
- Provide critical resolution of system issues through security solution services.
Future of DevOps
In the technological world, every technology including DevOps has its own role to take the corporate world in its hand. Here is the predictable future for the companies adopting DevOps.
- DevOps has been becoming a valued skill for IT people.
- Organizations will complete their project to weeks and months instead of years
- DevOps engineers will get more access and control toward the end-user
