What does modernization mean?

Modernization is the process of updating organizational processes, systems, and tools to the most current versions or best practices. In the context of enterprise applications, modernization involves transitioning legacy software to newer computing approaches, including modern languages, frameworks, and cloud infrastructure platforms.

The goal of application modernization is to improve an application’s performance, scalability, security and alignment with current business needs, rather than completely replacing it. This extends the lifespan of an organization’s software investments while taking advantage of technological advancements

Benefits of Application Modernization

Application modernization delivers a multitude of benefits – from enhancing performance, security and user experiences to enabling greater agility, cost savings and innovation.

It empowers businesses to optimize their existing investments while transforming to meet current and future demands in an increasingly competitive digital world. Here are the key benefits of application modernization:

Improved scalability and performance

Modernizing applications enhances their ability to handle increased workloads efficiently. It optimizes code, improves system architecture, and leverages the latest technologies to significantly boost application performance and scalability to accommodate business growth.

Enhanced security and reduced risk

Legacy applications are often incompatible with modern security standards, making businesses vulnerable to threats. App modernization addresses vulnerabilities, applies the latest security best practices, enables crucial updates and patches, and safeguards sensitive data.

Increased agility and faster time-to-market

Modernized applications are more flexible, allowing faster development and deployment of new features. This enables businesses to innovate rapidly, respond to changing market conditions and customer needs, and accelerate time-to-market for a competitive edge.

Better user experiences

Modernization improves user-facing elements like interfaces, navigation, and responsive design. Creating an enhanced, user-friendly experience leads to greater customer satisfaction, engagement, and loyalty.

Better user experiences

Reduced costs and increased efficiency

While requiring some upfront investment, application modernization reduces expensive maintenance of legacy systems and enables more cost-effective operations over the long term. It streamlines processes, automates tasks, and optimizes resources for improved efficiency.

Enables innovation and future-proofing

Modernizing applications allows organizations to leverage cutting-edge technologies like cloud, AI, machine learning, and IoT. This positions them to drive innovation, seize new opportunities, and build a flexible foundation for future growth in the evolving digital landscape.

Application Modernization Approaches

The optimal modernization approach depends on factors like an organization’s specific business drivers, application characteristics, complexity, criticality, and available resources.

Many enterprises pursue incremental modernization, starting with rehosting or refactoring before progressing to more advanced approaches like re-architecting or rebuilding. A thorough assessment of the existing application portfolio is crucial for determining the right modernization approach for each application. There are several common approaches to application modernization:

Rehosting (lift-and-shift)

This involves moving an application from one environment to another, such as from on-premises to the cloud, without making significant changes to the application’s architecture or code. It is the least intensive approach but may not be optimal for taking full advantage of cloud capabilities.


Replatforming lies between rehosting and refactoring. It involves making some code changes to the application so it can better utilize cloud technologies, without significantly altering the core architecture.


Evolve Your App Ecosystem

Integrate and orchestrate modern enterprise apps. Enable seamless data flow and process automation.


Refactoring involves restructuring and optimizing an application’s code and architecture without changing its external behavior. This is often done to break a monolithic application into microservices to leverage cloud-native capabilities like containers. Re-architecting takes this a step further by materially altering the application’s architecture and code to modernize it.


Rebuilding or rewriting an application from scratch while preserving its scope and specifications. This is done using cloud-native architectures and technologies for cases where an application requires a complete overhaul to meet current and future needs.


Eliminating a legacy application altogether and replacing it with a new custom application or off-the-shelf software package that better aligns with the organization’s needs.

Technologies and Tools for Enterprise App Modernization

Technologies and Tools for Enterprise App Modernization

The optimal set of application modernization technologies and tools depends on an organization’s specific requirements, existing applications, and target architecture.

A mix of cloud platforms, containers, microservices, APIs, low-code, DevOps, migration, and monitoring tools enables a holistic modernization approach. Here are some of the key technologies and tools used for enterprise application modernization:

Cloud Platforms

Cloud platforms like Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform are foundational for application modernization. They provide the infrastructure, services, and tools to host and run modernized applications in a scalable, flexible, and cost-effective manner.

Containers and Orchestration

Containers, such as Docker, package applications with their dependencies for portability and efficiency. Container orchestration platforms like Kubernetes and OpenShift automate the deployment, scaling, and management of containerized applications. They enable modern microservices architectures.


Microservices architecture breaks down monolithic applications into smaller, loosely coupled services that can be developed, deployed, and scaled independently. This improves agility, flexibility, and maintainability. Tools like service meshes (e.g. Istio) help manage microservices.

APIs and Integration

APIs (Application Programming Interfaces) enable communication and data exchange between different applications and services. API management tools like Apigee and Azure API Management help create, publish, monitor, and secure APIs. Integration platforms (iPaaS) connect applications, data, and processes.

Low-Code/No-Code Platforms

Low-code and no-code development platforms like Mendix, OutSystems, and Microsoft Power Apps allow building applications quickly with minimal coding. They enable citizen development and accelerate application delivery.

DevOps and Automation

DevOps practices and tools streamline application development, testing, and deployment. Continuous Integration/Continuous Deployment (CI/CD) pipelines automate application builds, tests, and releases. Configuration management tools like Ansible and Terraform codify infrastructure.

Cloud Migration

Cloud migration tools assist in assessing, planning, and executing the migration of applications to the cloud. They help in tasks like workload discovery, cost estimation, and data migration. Examples include AWS Migration Hub and Azure Migrate.

Application Performance Monitoring

Application Performance Monitoring (APM) tools monitor the performance, availability, and user experience of applications. They provide visibility into application behavior, identify issues, and aid in optimization. Examples are New Relic, AppDynamics, and Dynatrace.
