Operational Support and Performance

Keep your technology operation stable, fast and available

This service transforms legacy applications with obsolete technologies toward modern platforms (cloud-native, microservices, APIs) without needing to completely rewrite the system. Through architectural analysis, use of generative AI to accelerate refactoring, incremental modernization strategies (strangler pattern, feature flags) and preservation of validated business logic, the service reduces technical debt, improves maintainability, scalability and security while maintaining operational continuity. Ideal for companies with critical systems in obsolete technologies that need to modernize without the risk and cost of greenfield projects.

Operational Support and Performance - BITE servicios especializados

The Challenge

Companies operate legacy systems (COBOL, Visual Basic, ASP.NET Framework, monolithic applications) that work but are difficult to maintain, don't scale, have security vulnerabilities and slow innovation because any change is costly and risky. Rebuilding from scratch (greenfield) is prohibitively expensive, risky and takes years, while maintaining the status quo accumulates unsustainable technical debt and puts the business at competitive disadvantage. Without intelligent modernization strategies, companies are trapped between the cost of replacing and the risk of maintaining obsolete systems.

Our Value

Modernization Without Complete Rebuild

Incremental modernization strategies that update critical systems without big-bang rewrites, reducing risks and allowing continuous value delivery.

Technical Debt Reduction

Legacy code refactoring, obsolete dependency elimination, framework updates and modern pattern application that facilitate future maintenance.

Generative AI Acceleration

Use of AI (Azure OpenAI, GitHub Copilot) to accelerate code analysis, test generation, automated refactoring and code migration between languages/frameworks.

Validated Business Logic Preservation

Migration of complex business rules and logic validated by years of use, avoiding risk of implicit knowledge loss that occurs in complete rewrites.

How We Work

1

Phase 1: Legacy Code Assessment and Analysis

We analyze legacy source code identifying dependencies, cyclomatic complexity, technical debt, security vulnerabilities and coupling. We use static analysis tools (SonarQube, NDepend) and generative AI to map critical business logic. We prioritize modules according to criticality, complexity and business value.

2

Phase 2: Modernization Strategy Design

We define modernization strategy (strangler pattern, lift-and-shift, replatform, refactor, replace) per module. We design target architecture (microservices, cloud-native, APIs), establish incremental migration phases and define success criteria, quality metrics and rollback plan.

3

Phase 3: Incremental Modernization with AI

We execute code refactoring using generative AI to accelerate (method extraction, logic simplification, dead code elimination). We migrate modules incrementally, implement APIs to decouple components, create automated regression test suite and validate equivalent functionality between legacy and modernized versions.

4

Phase 4: Deployment, Validation and Stabilization

We deploy modernized versions using safe rollout strategies (canary, blue-green), monitor production behavior comparing with legacy baseline, validate performance and stability, and gradually redirect traffic from legacy to modernized version. We maintain rollback capability until confirming total stability.

Use Cases

.NET Framework to .NET Core Modernization

Scenario

Company with monolithic ASP.NET Framework (4.8) application on Windows IIS that cannot run in containers or scale horizontally, limiting growth capacity.

Outcome

Incremental migration to .NET 8 with modular architecture in Azure App Service, improving deployment time from 2 hours to 5 minutes and reducing hosting costs by 50%.

Monolithic System Refactoring to Microservices

Scenario

Java monolithic application with 500,000 lines of code where any minor change requires complete application deployment, generating risks and weeks of delays.

Outcome

Extraction of 5 critical microservices (billing, inventory, users) using strangler pattern, allowing independent deployments and reducing feature time-to-market by 60%.

Visual Basic 6 to .NET Migration with AI

Scenario

Custom ERP system in Visual Basic 6 that the company cannot maintain (scarce developers, no Microsoft support, critical vulnerabilities).

Outcome

AI-assisted migration accelerating code analysis and .NET equivalent code generation, completing modernization in 8 months vs 18-24 months estimated manually.

Deliverables

1

Legacy Code Assessment

Report with complexity analysis, technical debt, obsolete dependencies, security vulnerabilities and estimated modernization effort per module.

2

Modernization Strategy

Detailed plan with modernization strategy (strangler, replatform, refactor), target architecture, incremental phases, risks and mitigation plan.

3

Modernized Architecture Design

Target architecture diagrams (microservices, cloud-native, APIs), selected technology stack, applied design patterns and decision justifications.

4

Modernized and Refactored Code

Modules or components migrated to modern technologies (.NET Core, Node.js, Python, microservices) with clean code, automated tests and updated documentation.

5

6

Configured CI/CD Pipelines

Build, test and deployment automation (Azure DevOps, GitHub Actions) with safe rollout strategies (blue-green, canary) and post-deployment monitoring.

7

Updated Technical Documentation

Architecture, technical decisions, development guides, deployment runbooks and troubleshooting guides updated reflecting modernized system state.
