DevOps Automation

Introduction

DevOps is the most emerging field in today’s market. DevOps in simple language is a set of processes that unitedly bring software development through a collaboration of development and operations. The reason why DevOps is popular as it allows to create product much faster than it was by the traditional approach.  The main part of DevOps includes understanding the lifecycle of product development. Also, it helps to create better quality software, making sure that it will be deployed more quickly and reliably. This is achieved by collaboration between teams. Here teams refer to the Development team & IT Operations team. It is not just the collaboration between these two teams which allow delivering better software, but also the integrity between Development & Operation teams which results in improved software, delivered at a greater speed.

Software Development Evolution

The reason for the evolution of the DevOps is existing software development strategies/ methodologies over the years in response to business needs. Now let us briefly look at how these models evolved and in which condition they would work better.

We all aware of SDLC phrases that are used in software development processes. And also we know the Waterfall model which is very slow so it was evolved into Agile which saw development teams working on the software in short sprints lasting not more than two weeks.

Because of such a short release and development cycle of the product helped the development teamwork on client feedback and incorporate it along with bug fixes in the next release. While this Agile SCRUM approach provides speed with agility to development, it was lost on Operations which did not come up to speed with Agile practices. Traditional software development methods are not able to achieve collaboration between Developers and Operations Engineers still slowed down the development process and releases. Because of these drawbacks, we have a new advanced method i.e. DevOps methodology. It was born out of this need for better collaboration, integration and faster delivery. DevOps enables continuous software delivery with a faster resolution problem to fix and solve more complex problems.

Before DevOps, the IT business was going gaga regarding Agile Methodology wherever it absolutely was considered one thing higher and improved than waterfall Methodology. This really has businesses invest in Agile Development and revamp their operations for agile flow of development methods. But somewhere it was falling on its face because it couldn’t push the product or solution release. It was failing to deliver solutions in time. So many software Development teams and IT companies were left defeated when adopting this technique.

But now, DevOps came to the rescue. This doesn’t mean that Agile Development is gone permanently. There area unit several areas wherever Agile Development still proves to be terribly efficient and delivers results that have already allowed a number of the simplest code solutions. Agile is very close to the waterfall Methodology however it was a lot of up to date in nature and easier to adapt.

Now we are well understood about how DevOps is evolved, let us look at what is DevOps in detail.

What is DevOps?

The reason for the evolution of the DevOps is existing software development strategies/ methodologies over the years in response to business needs. Now let us briefly look at how these models evolved and in which condition they would work better.

DevOps is a software development technique that involves Continuous Development, Continuous Testing, Continuous Integration, Continuous Deployment and Continuous Monitoring of the software throughout its software development life cycle. Only in a DevOps Methodology, these activities are possible, This is not possible in the Agile or waterfall model, and that’s why Facebook and other top companies have chosen DevOps as the way forward for their future business goals. DevOps is preferred for high-quality software in very short development cycles which results in greater user satisfaction.

Now I think you understand the concept of DevOps but after understanding the life cycle all your concept will clear. Let us now discuss the DevOps lifecycle and explore how they are related to the software development stages depicted in the diagram below.

DevOps is a deep integration between development and operations. Understanding DevOps is difficult without knowing the DevOps lifecycle.

Here is temporary information about the continuous DevOps life-cycle:

1. Development

In this DevOps stage, the development of code takes place constantly. during this section, the complete development method is separated into small development cycles. This will benefit the DevOps team to speed up software development and delivery method with continuous monitoring.

2. Integration

In this stage, new functionality is integrated with the known code, and testing takes place. Continuous development is simply possible due to continuous integration and testing.

3. Testing

QA team use tools like selenium to identify and fix bugs within the new piece of code.

4. Deployment

In this section, the deployment method takes place continuously. it’s performed in such a way that any changes made any time within the code, shouldn’t affect the functioning of high traffic websites.

5. Monitoring

In this section, the operation team can lookout of the inappropriate system behavior or bugs that are found in production.

DevOps Tools with SDLC Phases

Now we all are aware of SDLC phases and how it’s useful in DevOps Life cycle. Now it’s time to understand Tools which is used under DevOps Methodology. And exact use and location of these tools in SDLC Phases.

As of now, you understood the DevOps Methodology. So we know the different Software Development phases are used for achieving DevOps Automation. But how is it possible? It’s possible using different tools in different SDLC phases. DevOps automation is started from the Coding phase so we can use GIT, JIRA tools for storing your source code at a central location that is accessible to other developers. And using JIRA we easily manage your project and track your bugs inside the projects.

The second phase is the build phase in which we are creating a build of your application source code and generate deployable artifact means output. Like war, jar or ear files. Using Ant, Maven, Gradle, etc. we can easily create a final build. After deploying this build into Testing Environment tester will test your product using different testing tools and techniques like Automation Testing using Selenium. We are able to configure your production environment on cloud premises and on-premises as well. AWS, GCC, and Azzure are most famous cloud providers are available in the market.

Now it’s time to configure numbers of devices simultaneously using scripts. Ansible, Puppet, and Chef are the most popular configuration management tools are available. Using these we can easily manage numbers of devices using simple commands and scripts like an Infrastructure as a code. Docker is a more advanced virtualization tool that provides a containerization platform for deploying artifacts. Nowadays most of the mobile and pc games and cloud applications are running on containers. Because of this heavy load, containers are increasing rapidly and it’s complexity as well. So managing container is a really tough task. But we have one more solution for that i.e. Kubernetes. It is used to manage numbers of containers clusters and maintaining docker nodes as well. The last Phase in DevOps lifecycle is Monitoring and most of the operational or support engineers work with this phase. For taking backups and continuous monitoring we can configure Nagios and Splunk tool.

Why is DevOps used?

DevOps allows Agile Development Teams to implement Continuous Development, Continuous Testing, Continuous Integration, Continuous Deployment and Continuous Monitoring of the software. This helps them to launch products faster with quality into the market.

Other Important reasons are:

1. Predictability: DevOps offers a significantly lower failure rate of new releases as compared to traditional software development methodology.

2. Reproducibility: In the Software development process Version is everything so that the earlier version can be restored anytime as per your interest.

3. Maintainability: Fault tolerance is very less so fewer efforts are required for recovery in the event of a new release crashing or disabling the current system.

4. Time to market: You know The DevOps methodology is faster than any other traditional methodology. DevOps increase the speed to market up to 50% through streamlined software delivery.

5. Greater Quality: DevOps is an integration of Developer and IT Operation team so it helps the team to provide improved quality of application development as it incorporates infrastructure issues.

6. Reduced Risk: It performs automation and also maintains security aspects through the software delivery lifecycle. It helps in the reduction of defects across the lifecycle.

7. Resiliency: The Operational state of the software system is more stable as compared to other methods, secure, and changes are auditable.

8. Cost Efficiency: Most of the DevOps tools are open source and it is easily available on the internet. because of this cost efficiency in the software development process which is always an aspiration of IT companies’ management.

9. Breaks large code base into small pieces: DevOps is based on the agile programming method. Therefore, it allows for breaking larger codebases into smaller and manageable chunks.

DevOps Principles

Here, are six principles that are essential when adopting DevOps:

1. Customer-Centric Action: It should take customer-centric action for that they must constantly invest in products and services.

2. End-To-End Responsibility: The DevOps team got to offer performance support until they become end-of-life. This enhances the amount of responsibility and also the quality of the product built.

3. Continuous Improvement: DevOps culture focuses on continuous improvement to reduce waste. It incessantly hurries up the development of products or services offered.

4. Automatize everything: Automation is a life principle of DevOps method. This is not just for the software system development but additionally for the whole infrastructure landscape.

5. Work together with a team: In the DevOps culture role of the designer, developer, and tester are already defined. All they required to try and do is work together with the team with complete collaboration.

6. Monitor and check everything: the DevOps team needs to possess a strong observation and testing procedures.
