Your legacy applications won't scale on their own.

We analyze your current systems and define the most suitable modernization strategy—without losing business continuity along the way.

Modernization

Most organizations don't have a migration problem: they have a problem with accumulated technical debt. Monolithic applications, undocumented dependencies, unsupported technologies. Modernization in Nublit is the process of transforming those systems into platforms cloud native — scalable, maintainable, and ready for what's next.

What is included?

Technical Debt and Dependency Analysis

Application portfolio survey: technologies, integrations, criticality, and support status.
Identification of candidates for modernization.
Prioritization by impact and effort.

Modernization Strategy

Re-host: move without changing (quick start point)
Replatform: optimize for the cloud with minimal changes.
Re-architect: Redesign to take full advantage of cloud-native capabilities.

Migration to containers and microservices

Containerizing applications with Docker.
Decomposition of monoliths into microservices where appropriate.
Orchestration with Kubernetes.

Adoption of managed and serverless services

Replacing self-managed components with AWS native services.
Operational reduction and resilience improvement.
Use of services such as RDS, Lambda, SQS, EventBridge, among others.

Integration with DevOps pipelines and observability

The modernized application integrates with CI/CD practices.
Infrastructure as Code (IaC).
Monitoring from day one.

Operational continuity during the process

Planning each stage to keep production systems running during transformation.
The business doesn't stop during the process.

Value proposition

Greater agility

Faster iterations, more frequent deploys, less risk per change.

Operating cost reduction

Less administrative overhead when adopting managed services.

Real scalability

Architecture grows with demand, without over-provisioning.

Lower technical debt

More maintainable systems, with teams that can iterate with confidence.

End-to-end support

From diagnosis to operation of the modernized system.

Who is this service for?

Organizations with legacy applications that limit their ability to grow or generate increasing operational costs.

Companies that have already migrated to the cloud but are still operating with an architecture designed for on-premise.

Development teams that want to adopt modern architectures—microservices, containers, serverless—but don't know where to start.

Organizations that need to modernize their applications to incorporate data and artificial intelligence capabilities.
