Application Modernization

Strategic Transformation

The systematic evolution of current applications and infrastructure to facilitate cloud-based services, explore new business opportunities, drive innovation, and minimize technical debt is referred to as application modernization.

Business-Driven Evolution

Numerous organizations project a 50% expansion in their application portfolios over the next two years. This growth is driven by the necessity for businesses to enhance application functionality to deliver superior customer experiences and services.

Modernization Approach

Organizations that modernize their workloads employ a combination of strategies, such as rehosting, replatforming, and refactoring, to transition applications to the cloud.

Why Modernization Now?

Legacy systems were built to last, not to evolve.

Over time, they become:

Costly to maintain, especially with licensed platforms like Windows Server, Oracle WebLogic, or MSSQL/Oracle Databases

Slow Time-to-Market, legacy architectures delay releases and decrease your ability to compete.

Incompatible, lacking support for cloud, mobile, or modern security standards

Risky, performance issues, security gaps, and fragmented data across environments.

In today’s cloud-first world, agility is non-negotiable. Application modernization is the key to remaining relevant, secure, and scalable.

Reducing technical debt, cutting licensing costs, and preparing systems to meet both current and future demands.

Application Modernization Strategy Flyer Learn our proven approach to transforming legacy systems.

Modernization Strategy

By modernizing your application workloads on the cloud, you can achieve license freedom, cost reduction, leverage containers and serverless technologies, and transition to microservices and cloud-native architectures.

Cost-Effective Architecture

When deploying on the cloud, it is typical to achieve a reduction in payback periods to six months and decrease the total cost of ownership (TCO) by up to 64%.

Sustainable Partnership

Kloia forges long-lasting partnerships focused on continuous improvement, aiding in the advancement of your applications through various transformation cycles.

Business-Oriented Approach

Cloud migration and application modernization strategies are determined by your organization's specific business requirements rather than contractual agreements or licensing constraints.

Balanced Automation

Kloia strategically deploys automation, adeptly balancing upfront investments with sustainable long-term operational savings.

Measured Innovation

The modernization methodology ensures that innovation is realized without sacrificing stability, carefully incorporating emerging technologies.

Rewriting

Rebuild legacy applications from the ground up, preserving business logic while adopting modern development stacks, architectural standards, and DevOps practices.

Replatforming

Transition workloads to containerized, cloud-native infrastructure using Docker, Kubernetes (EKS), and AWS-native services for improved scalability and modern delivery pipelines.

Refactoring

Version Upgrades: Update runtime environments, frameworks, and dependencies (.NET Framework → .NET 8+)

Architectural Refactoring: Implement modern patterns including Hexagonal Design, CQRS/Event Sourcing, Microservices, BFF, Reactive Programming, and Microfrontends

With AWS Transform capabilities transformation capabilities for .NET, we were able to reduce the transformation efforts and estimate we can save about 40% of the costs by modernizing the .NET Framework applications into cross-platform .NET and running them on Linux. With AWS Graviton-based processors, this figure may decrease by an additional 10%. I'm excited to see continued innovation as AWS build on this strong foundation to support even more use cases.

Application modernization is the process of updating legacy systems to modern architectures, cloud infrastructure, and development practices. It reduces technical debt, improves scalability, and enables faster time-to-market while maintaining your critical business logic.
Yes. We conduct comprehensive application modernization assessment to evaluate your current systems, identify optimization opportunities, and create a detailed roadmap. Our application modernization assessment template includes technology stack analysis, architectural patterns, cloud readiness, and cost-benefit projections.
Containerizing and orchestrating applications with Kubernetes (especially AWS EKS) provides auto-scaling, high availability, and simplified deployment pipelines. Application modernization with Kubernetes reduces operational overhead, improves resource utilization, and enables seamless cloud-native workflows.
Serverless application modernization refactors legacy systems to use cloud-native, managed services like AWS Lambda, DynamoDB, and SQS. This eliminates infrastructure management, reduces costs through pay-per-use billing, and accelerates scaling without provisioning servers.
Kloia is a global application modernization partner with offices in Dubai, London, Istanbul, Amsterdam, Delaware, and Hyderabad. We offer advanced application modernization solutions in these locations and many other parts of the world.
As an AWS Premier Partner, Kloia is a trusted cloud modernization partner with advanced DevOps capabilities. We provide Infrastructure as Code, continuous delivery pipelines, observability solutions, and automated security practices to ensure your modernized applications run efficiently and securely in the cloud.
QA modernization is a critical component of our approach. We implement modern testing frameworks, continuous integration, automated testing pipelines, and shift-left testing practices. This ensures quality at every stage, reduces defect escape rates, and supports rapid release cycles alongside your application transformation.
Our application modernization review covers code analysis, dependency mapping, performance profiling, security vulnerabilities, cloud readiness, licensing costs, and architectural gaps. We deliver a prioritized roadmap with recommendations on rewriting, replatforming, or refactoring your legacy systems.
Timeline varies based on complexity, system size, and chosen strategy. A small refactoring might take 3–6 months, while a full rewrite could span 12–18 months. We create realistic project schedules during the assessment phase and maintain agile delivery practices to show progress and adapt as needed.
Typical benefits include 30–50% reduction in licensing costs, 2–4x faster deployment cycles, improved system reliability, enhanced security posture, and accelerated feature delivery. Exact ROI depends on your starting point, but most organizations see measurable returns within 12–18 months post-launch.
