Build & Modernize
Make monolithic apps future-ready.
Legacy apps lead to spaghetti architecture that no one signed up to manage. We’ve got monolith-to-microservices down to a science. Starting with an assessment powered by Presidio AI, we deliver a phased roadmap aligned to business goals, and stay until you have a modern product.
Where clients get stuck.
- Long deployment cycles slow every release
- Debugging depends on one or two key people
- Datacenter limits cause availability problems
- Security gaps and technical debt pile up unaddressed
Application Modernization Case Studies
Where Presidio modernized old custom applications to cloud-native revenue drivers.
EHE Health had an aging patient portal and no access to the source code. The only choice was to boldly go cloud-native. After a modernization assessment, Presidio’s dedicated engineering pod rebuilt the HIPAA-compliant app on microservices and went from concept to MVP in twelve weeks.
Application Modernization Benefits
Agentic, Presidio AI-powered discovery.
Our App Mod Assessment evaluates source code, integrations, data, and security posture; identifying cloud-native and microservices opportunities.
Microservices > monoliths.
We re-architect to cloud-native microservices and APIs, so apps scale on demand, deploy faster, and shed the dependencies that made them fragile.
Secure design from the start.
Security designed in from the first sprint, not patched in after launch. We assess security posture and access controls, then build remediation into the modernization plan.
Dedicated engineers at your service.
Named experts in a self-contained pod with engineering, infrastructure, QA, and UI skills deliver the work, with automated builds and high test coverage.
Modernize at any scale.
Whether it’s a single end-of-life app, a department portfolio, or an org-wide initiative, we scope to the scenario and the decision drivers, from app maintenance cost to board-level KPIs, and sequence accordingly.
Designed for AI traffic.
AI workloads generate traffic patterns that legacy three-tier networks were never designed to carry. We design network fabric for AI throughput from the start.

App Modernization FAQs
What application and product leaders ask before committing to a modernization program.
Application modernization is the work of moving custom applications to modern, cloud-native architectures that are more secure, scalable, and cost-efficient. It typically means re-architecting monoliths to microservices and APIs, and addressing security, technical debt, and datacenter limits along the way.
