Application Modernization

The Challenge

Business fit

The application no longer meets current business requirements.


The application constrains the business from leveraging new business opportunities or addressing disruptions.


The application and its supporting ecosystems are not able to keep up with the pace of change, or those changes may come with an unacceptable level of cost and risk.


The total cost of operating, maintaining and changing the application is too high in relation to its business value.


The high complexity of the application creates various problems and is a major factor in maintainability as it impacts time, cost and risk of implementing changes.


The application poses security, compliance, supportability and scalability risks. In older application platforms and languages, the risk of a skills shortage is often a major concern.

The Solution

Application modernization patterns:

Incremental Modernization – Adopting an incremental approach to modernization can mitigate risks and manage costs. This strategy involves gradually upgrading components of the system rather than undertaking a complete overhaul. Techniques such as refactoring, rehosting, re-platforming and containerization allow for phased improvements.

From monolith to microservices – The most common pattern of application modernization involves refactoring and breaking down a monolithic application into a collection of small, loosely coupled microservices.

Leveraging Cloud Technologies – Migrating to cloud platforms offers scalable, flexible, and cost-effective solutions. Cloud providers offer a range of services that support modern architectures, such as microservices, serverless computing, and DevOps tools. The cloud also provides robust security and compliance features that can enhance the overall reliability of applications.

Automation and DevOps Practices – Automation tools and DevOps practices can streamline the modernization process. Automated testing, continuous integration, and continuous deployment (CI/CD) pipelines accelerate development cycles and improve code quality. Infrastructure as Code and configuration management tools ensure consistent and efficient deployment environments.

The Business Impact

Improve quality of service – Transforming legacy applications to leverage the cloud can improve your quality of service by enhancing your ability to seamlessly scale to accommodate increasing levels of usage.

Realize cost savings – Modernizing your applications enables you to reduce the costs of on-premises IT infrastructure and IT administration, plus you can reduce licensing costs by migrating to open source databases.

Create new revenue streams – Application modernization gives your organization the chance to develop new processes or services that provide added value to your customers, resulting in new streams of revenue.

Increase customer satisfaction – Modernizing an application can improve the customer experience with changes like enhancing the user interface, adding new features or services, or automating processes that were manual prior.
