Seamless collaboration during the entire software development lifecycle helps teams complete projects successfully and achieve higher customer satisfaction. Not only does it result in faster deployment and delivery, but it also reduces friction among team members. DevOps tools tick off all these aspects, which is why DevOps is witnessing surplus adoption in recent years.

A report published in November 2019 by DZone says that the DevOps market generated $2.9 billion in 2017, and this number is projected to reach around $6.6 billion by 2022. Despite its continuous adoption in organizations of different scales, many are confused about the real meaning of DevOps.

One of the many misconceptions about DevOps is thinking of it as just a tool, while others are confused about its approach, philosophy, culture, and aims. There is no single DevOps tool but rather a set of DevOps tools or toolchains essential for DevOps engineers, developers, operators, and others in the team.

This article introduces you to DevOps, its practices, culture, benefits, and more. Furthermore, we’ve also hand-picked the 30 best DevOps tools for various stages in the software development lifecycle.

Let’s begin!

What Is DevOps?

DevOps is the amalgamation of practices, cultural philosophies, and tools to increase the ability of an organization to deliver IT services and applications faster than traditional development processes.

By adopting DevOps, organizations can improve their products, serve the customers well with quick feedback and fixes, get a competitive edge in the market, and achieve their business objectives faster.

DevOps = Development + Operations

Simply put, DevOps is a mindset that helps remove roadblocks in traditional development processes and operations and shortens the software development life cycle.

This model enables development teams and operations teams to work together effectively during the entire software lifecycle, from the development phase and testing to deployment and operations.

The use of technology in DevOps implementation is also one of the critical aspects. Numerous DevOps tools leverage dynamic and programmable infrastructure and are available for automation, testing, configuration, integration, delivery, and other processes.

The Origin of DevOps

Patrick Debois coined the term “DevOps” in 2009. He is a Belgian consultant, agile practitioner, and project manager, who became one of the early DevOps leaders and formed this word by combining “Dev” as in development, and “Ops” as in operations.

Here, “Dev” doesn’t only mean developers, but everyone involved in developing a software product from disciplines like Q&A, development, testing, planning, etc.

Similarly, “Ops” is an umbrella term for everyone involved in the operations team, including system engineers, database administrators, system administrators, security experts, network engineers, release engineers, operations staff, and others.

As explained in the previous section, DevOps is a mindset or culture. And this mindset is not something that was carved out of a single rock.

Instead, it originated in the best minds years ago and was nurtured and conceptualized by forward-thinking experts from various IT disciplines.

Many fundamental DevOps ideas are inspired by practices like Lean, Agile, enterprise system management, The Toyota Way, and Deming’s Plan-Do-Check-Act method.

In 1993, the Telecommunications Information Networking Architecture Consortium defined a Model of Service Lifecycle. This model combined telecom operations with software development.

Some professionals say DevOps emerged slowly as a method opposing the “top-down” ITIL prescriptive approach. Instead, DevOps favored a “bottom-up” approach and gained traction, providing a flexible software development practice instead of a rigid framework.

In 2009, “Devopsdays,” the first-ever conference based on DevOps, was held in Belgium. Patrick Debois laid the foundation of this conference, which spread as a movement to other parts of the world.

Let’s discuss the two main antecedent methods of DevOps:

1. Enterprise Systems Management (ESM)

ESM rose in the 2000s, whose approach of running various systems was still in a primitive state. This is why efforts were initiated to evolve it. This phase saw the development of ITIL Lite and Visible Ops methodology. Additionally, more minor, open source solutions for end-to-end system management started surfacing, including Zenoss, Hyperic, Spiceworks, etc.

Amongst people involved initially in DevOps development, many were system admins who introduced the main best practices of ESM to DevOps. These practices include configuration management, automated provisioning, toolchain approach, and system monitoring.

More conferences were held in 2008 and 2009, focusing on operations and web performance and sharing best practices around these processes. Slowly, provisioning tools such as Chef and Puppet were released, and it made people think more about these new practices and how to implement them.

2. Agile Development

Parallelly, agile development was growing in the software development world. It enables close collaboration between developers, product managers, QA, and even customers to fill the gaps and accelerate delivering a better product.

The primary focuses of this movement were processes and analogies, including lean manufacturing, kanban processes, and system administrators.

Many organizations and companies have started including DevOps in their software development cycle to expedite the process and achieve faster and better results.

Why Was DevOps Created?

System administrators and developers could disagree on various grounds, but they agree that both must meet the demands of growing customers’ needs.

This demand includes the need for new features, revenue streams, services, and better products in addition to a system that’s more secure, stable, high performing, and devoid of interruptions and outages.

All these needs require the involvement of both system admins and developers to present a better service or product before the customers.

Now, the problem is companies may get overwhelmed with these frequently changing and ever-evolving customer demands. They may feel the need to choose one option between:

Unarguably, both options seem unacceptable because they won’t help an enterprise provide the best possible solutions to their customers.

It created the dire need for a system or practice that could balance both sides of the production environment, development, and operations.

And the solution to this problem is DevOps!

It was created to strike a balance on either side, so even if the developers craft a faster product, operations can find ways to stabilize the system.

DevOps is a way that can integrate all the people associated with software development to its deployment that includes business users, security engineers, developers, system admins, test engineers, QA, and others.

All of them will be integrated into a highly automated, single workflow sharing a common goal: to deliver high-quality software rapidly that can meet user demands while ensuring the stability and integrity of the system.

And this is how DevOps came into being.

Next, you may think about why you should use DevOps in the first place when you have other options around.

Don’t worry. The answer is right ahead!

What Are the Benefits of DevOps?

Benefits of DevOps, illustration.

Benefits of DevOps

Teams adopting DevOps culture, tools, and practices collaborate effectively, become more productive, deliver better products faster, and achieve higher customer satisfaction to fulfill business goals.

DevOps helps enhance business agility by offering a productive environment that nurtures mutual collaboration, fruitful communication, and seamless integration across teams in an organization, no matter where the team members are present on the globe.

According to an UpGuard report, 63% of organizations implementing DevOps experienced improved software deployments and released products more frequently.

Let’s get better clarity on how DevOps can help you and benefit your team.

1. High Development Speed

DevOps model helps developers and operational teams automate everything to innovate faster, produce high-quality software with high velocity, adapt to changes quickly, and grow their business efficiently.

2. Rapid Delivery

You can increase the speed and frequency of your releases, adapt short release cycles, and reduce time to market with the help of DevOps. When you release the product and its features quickly, you can quickly perform quick bug fixes, respond to customer needs faster, and get a competitive edge in the market with improved quality products.

3. System Stability & Reliability

DevOps practices and tools ensure software quality and stability along with all the infrastructure changes introduced. Practices like CI/CD and real-time monitoring come in handy to maintain system stability. This, in turn, increases the reliability of your software in the users’ eyes.

4. Scalability

Managing and operating development processes and infrastructure at scale is better with DevOps. Automation with consistency allows you to manage changing and complex systems efficiently with lower risks.

5. Security

DevSecOps was introduced in the pipeline, so everyone in the team is responsible for maintaining security, not just your security team. It helps you track security issues, detect them, and resolve them before they could cause any harm.

Hence, you can stay compliant and better control security using configuration management methods, automated compliance policies, and granular control.

6. Higher Customer Satisfaction

Due to accelerated software delivery, you will have enough time to collect customer feedback, track the software progress at different stages, and bring about suggested changes.

Hence, when you work on the flaws and improve software functionality based on user demands, it increases their satisfaction level. They trust your products more and become loyal customers.

7. Competitive Edge in the Market

Adapting quickly to changing market demands is the key.

DevOps implementation helps you in quick software releases, rapid delivery, high-end functionalities, tighter security, and improved customer satisfaction. You get a powerful competitive edge over others doing it the traditional way.

Plus, it also helps reduce the cost involved in the entire software cycle and maximize ROI and profitability.

How Does DevOps Work?

As we highlighted, the development team and operations work together under the DevOps ecosystem during the entire software lifecycle, developing wide-ranging skills.

Sometimes, security and QA teams also integrate tightly with DevOps, and when security is the main focus, it’s known as DevSecOps.

They use practices to automate slow and manual processes. For this, they leverage technology stack and tooling to evolve and operate applications faster and with reliability.

Let’s see how DevOps works throughout the software lifecycle.

1. Planning

DevOps teams define and ideate the software they will build while finding the customer pain points and how to solve them through the product. They describe the capabilities and features of the software.

They also plan which tools to use to ensure the team knows the tasks at hand, how many are completed, whether they can meet deadlines or not, etc.

2. Development

In the development phase, the DevOps teams perform coding, reviewing, integration, and deploying into different environments. The teams are dedicated to innovating quality products rapidly while maintaining productivity and stability.

They use DevOps tools like Chef, Terraform, Ansible, Kubernetes, etc., and automate manual and repetitive tasks. They iterate the tasks in smaller increments through continuous integration.

3. Testing

Testing is done for each code to check whether it contains any bugs or errors that could reduce the effectiveness and performance of the final product. It also helps elevate the customer experience.

For this, the DevOps tools used are Selenium, Sentry, etc.

4. Deployment

Next, DevOps teams deploy the software into a production environment reliably and consistently. This phase also involves configuring and deploying the fully controlled foundational infrastructure of the environments used.

Additionally, the DevOps teams need to define a well-crafted release process and establish automated gates to move software between stages before they are available to the end-users. This way, automation helps them produce a product with greater confidence and ease.

DevOps tools for deployment are CircleCI, Bamboo, etc.

5. Operation

The operation phase includes monitoring, maintaining, logging, and troubleshooting software in production environments.

DevOps teams aim to ensure system stability, reliability, and high availability in addition to zero software downtime while strengthening governance and security.

For this, they need complete visibility into the software and the core systems in addition to rich performance measurement, actionable altering, collecting user feedback, and more.

DevOps tools used in this phase are Prometheus, Nagios, New Relic, etc.

What Is DevOps Culture?

DevOps culture plays an important role in shaping how DevOps is implemented. It comprises a set of values that people embody while working and collaborating. Committing to a DevOps culture creates a highly productive environment for everyone included in the team.

DevOps culture involves:

1. Shorter Product Release Cycle

DevOps teams need to remain agile throughout the software lifecycle to release it in a shorter time frame. By maintaining shorter production release cycles, risk management and planning become easier and faster since each process is incremental and helps reduce the impact on system stability.

It also allows you to react quickly and adapt to changing customer needs while being competent.

2. Visibility, Collaboration, and Alignment

Visibility is the first thing that is required in the DevOps teams. Each team must always share their priorities, concerns, processes, and development among themselves so that everyone could remain on the same page.

After they have complete visibility on the work progress, development and operation teams must work together effectively with no communication gaps for rapid delivery.

While collaborating, DevOps teams must also align with the business goals, keeping in mind the timeline, quality, and ethics.

3. Accountability

When teams align, each member is accountable for their work, project completion, and successful delivery. Developers are accountable for quality and innovation during the development phase, and for the stability and performance their codes can bring about during the operation phase.

Similarly, IT operators must include security, compliance, and governance in the software during the development phase while maintaining high monitoring standards, quality checks, performance measurement, testing, and troubleshooting.

4. Growth Mindset

DevOps culture fosters a growth mindset among each member of the team and the team as a whole. Even if they fail, they examine the reasons behind their failure and implement the learnings, so they don’t commit the same mistakes again while improving continuously.

As a result, they accelerate towards innovation, take feedback seriously, increase customer satisfaction, and evolve based on market changes.

7 Essential DevOps Practices

While adopting a DevOps culture, you need to implement certain practices during the entire software lifecycle to bring DevOps’ real concept to life.

These practices help automate, improve, and accelerate various phases of the software lifecycle, from development to operation and deployment.

1. Agile Software Development

Agile is one of the software development approaches that focuses on team collaboration, higher adaptability to changing demands, user feedback, and shorter release cycles.

It’s different from other traditional frameworks like Waterfall that involve longer release cycles with sequential phases.

Agile incorporates two widely famous frameworks, Scrum and Kanban.

2. Continuous Integration (CI) & Continuous Delivery (CD)

Continuous integration is a software development practice where developers merge or integrate code changes into the primary code branch frequently. It includes automated testing that runs each time a new code is introduced to keep the primary code branch stable.

Next, continuous delivery involves automated deployment of software versions into the chosen production environment. DevOps teams can enable updates more frequently using automated deployment and reduce the number of issues occurring on deployment.

These two practices are together called continuous integration and continuous delivery (CI/CD). It includes complete automation of all the processes from coding to deployment and allows teams to remove operational overheads, human errors, and repetitive steps.

Hence, DevOps teams can emphasize building codes and deploying them quickly with lesser risks. Additionally, you can deploy more rapidly in small increments, become agile, and more confident and productive in running your codes.

3. Infrastructure as Code (IaC)

IaC defines system topologies and resources to allow your team to manage the resources during the coding phase reliably in a controlled manner. You can store and version those definitions in a version control system, so your team can review and revert quickly. It also helps reduce human errors in complex production environments.

4. Version Control

Version control involves managing codes in multiple versions with revisions and modification history, so it becomes easy to review the codes and recover them.

It’s an essential DevOps practice like CI/CD and IaC that helps your development teams to collaborate more effectively, store codes safely, divide tasks between your team members, merge changes, handle conflicts easily, and roll back code changes if needed.

Version control can be implemented using systems like Git.

5. Configuration Management

Managing system resources, including servers, databases, and virtual machines, is configuration management. You can use different DevOps tools available for this, such as Chef, Ansible, etc.

These tools help you roll out modifications systematically, and in a controlled way, so there remains no risk of changing the system configuration. DevOps tools also track your system state in addition to preventing configuration drifts that may lead to instability.

DevOps teams usually practice configuration management with IaC so that both configuration and system definition are effortless to automate, enabling teams to operate complex production environments with scalability.

6. Continuous Monitoring

Continuous monitoring is useful to get complete visibility into the health and performance of your overall application stack in real-time, from the infrastructure to high-end software components.

Monitoring includes metadata, telemetry (event logs and data), and alerts for a set of predefined conditions. DevOps teams draw meaningful insights that can help them mitigate issues faster. They can find ways to improve software quality in the next development cycles by using the information collected.

7. Microservices

Microservices is an effective design approach or architecture to build an application in several small services. These services have separate processes, and they interact with other services via a specific interface, such as an HTTP-based API.

Microservices are designed based on business capabilities, and each of them has a single purpose. They are built using different programming languages or web frameworks, and you can deploy them separately as individual services or as a cluster of services.

Who Uses DevOps and for What Purpose?

From enterprises to early-stage start-ups, DevOps is being adopted into IT companies across the globe. Here are some of the organizations that have implemented DevOps:

Apart from businesses, DevOps is a great approach for individuals like:

What Are DevOps Tools?

DevOps works in the cross-functional mode, involving various tools of various kinds and purposes, instead of just a single tool. These tools are also known as DevOps toolchains, as discussed above.

The tools help throughout the software production lifecycle, including development, management, and delivery.

The organization that uses DevOps practice coordinates these tools and fits each one of them into one or more production activities like planning, creation, verification, packaging, releasing, configuring, monitoring, and version control.

We have segmented various DevOps tools based on the production activities that they can fit into.
