Competitive differentiation keeps business enterprises agile, trendy, competitive, and user-friendly. Legacy applications do not quite fit into driving modern digital transformation. This is because they do not lend themselves to being adaptable or compatible with the latest systems, frameworks, or platforms. A robust application modernization strategy can help transform a business's legacy applications using modern technologies and architectures. Using cloud-based services like serverless computing, microservices, containers, and other DevOps methodologies may then be made possible by such systems.

In today's fast-paced digital environment, businesses always try to stay ahead of the curve. Modernizing applications is one of the key strategies businesses employ to achieve this. The process involves updating, enhancing, and optimizing existing applications to meet business needs. DevOps plays a pivotal role in this modernization journey, often centered on digital product engineering. It acts as the catalyst that ensures seamless, efficient, and collaborative development and deployment processes. Statistically, the market value of application modernization stood at $15.2 billion in 2022. It is expected to grow at a CAGR of 16.7 percent to reach $32.8 billion by 2027 (source: marketsandmarkets).

DevOps acts as an enabler when taking an application modernization approach. It empowers teams to collaborate efficiently, respond to changing requirements swiftly, and deliver modernized applications that meet the demands of today's users. As businesses evolve, embracing DevOps principles will be the cornerstone of their successful application modernization journey. These will ensure their software remains robust, secure, and user-friendly in the face of technological advancements and market demands. This blog explores the role of DevOps in application modernization. However, let us first understand why application modernization is needed.

The Need for Application Modernization

It is essential for business enterprises to align with market demands, given the pace at which requirements change. A legacy application can stifle the growth of a business enterprise. The business enterprise, on its part, often faces a slew of challenges when it comes to modernizing a legacy application.

■ Legacy applications made of monilithic architecture are difficult to update.

■ Legacy applications demand a lot of investment and effort to upgrade.

■ Legacy applications contain several security risks and vulnerabilities.

■ Legacy applications come in the way of organizational agility.

How DevOps Accelerates the Pace of Application Modernization

DevOps methodology streamlines development and operations processes and helps them collaborate to generate better business outcomes. The various ways it accelerates the pace of application modernization are mentioned below:

1. Agile Development and Collaboration: DevOps practices promote agile development methodologies, breaking down traditional silos between development and operations teams. DevOps ensures that every stage of the application modernization process remains streamlined and efficient by fostering collaboration, communication, and integration among these teams. Developers and operations personnel work hand in hand, leading to faster feedback loops, quicker issue resolution, and accelerated development cycles.

2. Continuous Integration and Continuous Deployment (CI/CD): These pipelines are at the core of DevOps practices. They allow automated code integration, testing, and deployment, ensuring that changes are rapidly implemented, and issues are identified early in development. In application modernization, CI/CD pipelines facilitate the seamless integration of new features, enhancements, and bug fixes into existing applications. This results in a continuous delivery model where updates are rolled out in smaller increments, reducing risks and enhancing the user experience.

3. Infrastructure as Code (IaC): Modern applications rely on complex and dynamic infrastructure. IaC, a core DevOps principle, allows infrastructure provisioning and management through code. This approach ensures consistency across environments, enabling development and operations teams to collaborate effectively. In the context of application modernization, IaC provides the flexibility to create, modify, and scale infrastructure components as needed, aligning the application with evolving business requirements.

4. Monitoring and Feedback Loops: DevOps practices emphasize continuous monitoring and feedback loops, enabling teams to detect issues, gather performance insights, and analyze user behavior. By leveraging product engineering services, businesses can assess the impact of modernization efforts on application performance and user satisfaction. Real-time feedback allows teams to make data-driven decisions, prioritize enhancements, and refine the modernization process iteratively.

5. Security Integration: Security is paramount in modern application development. DevOps practices incorporate security measures throughout the development lifecycle, ensuring that security is not a bottleneck but an integral part of the process. By integrating security checks, vulnerability assessments, and compliance audits into CI/CD pipelines, DevOps teams can identify and address security issues early, safeguarding the modernized applications and the sensitive data they handle.


In the digital transformation era, enterprise application modernization is not just a choice but a necessity for businesses aiming to stay competitive. DevOps practices provide the essential framework and tools to drive successful modernization initiatives. By embracing agile methodologies and a host of other measures, businesses or application modernization services can confidently navigate the complex landscape of application modernization.
