Application Modernization

Transform Legacy Applications into Cloud-Ready, Future-Proof Systems

We modernize legacy systems to improve agility, performance, and long-term sustainability - without disrupting the business that depends on them today. Structured, phased transformation that keeps the lights on throughout.

Assessment & Roadmap

Know what you have before you decide what to change with rigorous portfolio assessments.

Architecture Modernization

Build systems that change as fast as your business does with cloud-native refactoring.

Experience & Optimization

Modernize what users see and what engineers maintain with UX updates and debt reduction.

Together, these three pillars create a multidisciplinary approach where business strategy, technical feasibility, and user experience converge to produce innovation that works.

No Clear Picture

Application portfolios grown organically over years. What you're running, what it costs, what it depends on - often isn't understood until something breaks.

Monolithic Architectures

Everything connected to everything. Changing anything is risky. Deployments slow, scaling expensive, new features fragile.

Not Built for Cloud

On-premises infrastructure creates cost, capacity, resilience constraints. Migration done wrong introduces more risk than it removes.

Outdated & Accumulating Debt

Legacy UIs frustrate users. Aging technology stacks accumulate debt faster than teams can pay it down—blocking modernization above.

Modernization Benefits:

Evidence-based decisions, not instinct

Build, deploy, scale independently

Minimal business disruption

Risk managed at every stage

Competitive UX + sustainable code

Technical debt quantified & resolved

Why Enterprises Choose Tarento to Modernize

Strategy-first modernization that balances innovation with business continuity — minimizing risk while delivering full-stack transformation.

OUR SOLUTIONS:

Portfolio-First Thinking : We start with honest assessment - what to modernize, retire, re-platform, and in what order. Strategy before execution.
Hybrid & Phased by Design : Big-bang modernization carries big-bang risk. Our approach is incremental -value at each phase, business continuity throughout.
Cloud-Agnostic Expertise : AWS, Azure, GCP - we recommend the right platform for your workloads and compliance requirements, not single-vendor defaults.
Architecture + Experience : We modernize the full stack—architecture, APIs, and user experience. Modernization felt by users, not just engineers.
Technical Debt as Business Risk : We treat technical debt as a business problem with financial cost. Quantify it, prioritize it, systematically resolve it.

Case Study

Application ModernizationMicrosoft Power PlatformRPA & AI

Modernizing Business Applications with Microsoft Power Platform

Challenge:

A leading water technology company operating in 150+ countries needed to modernize its existing SharePoint on-premises solutions and stabilize an unstable application environment. The organization wanted to move toward a more agile Microsoft Power Platform setup, streamline Office 365-based process automation, and use RPA and AI Builder to extract content from invoices and architectural diagrams.

What We Did:

Stabilized the customer’s existing system environment through quality support and architectural services
Optimized the environment with a cost-effective development and operations model
Modernized existing business solutions using low-code Microsoft Power Platform
Transformed workflows, InfoPath applications, and server-side solutions into no-code Power Platform alternatives
Implemented automation for daily repetitive tasks such as ticket creation and content repository search using a bot
Enabled a 24×7 support model based on solution manager alerting

Results:

Streamlined support processes with defined SLAs

Existing workflows, InfoPath applications, and server-side solutions modernized into Power Platform-based alternatives

Repetitive operational tasks automated to improve process efficiency

Tarento became a trusted partner for the customer’s Power Platform activities
