Enterprise .NET Application Development & Azure Modernization Services
Cut technical debt, accelerate release velocity, and run mission-critical software with SLA-backed confidence.
Cetas is a trusted Microsoft technology partner focused on .NET application development, Azure migration, and application management. We have supported 600+ engagements across 20+ countries over 16+ years, with AMS support models built around measurable SLA response times.
Core Microsoft Engineering Services
From bespoke software builds to cloud infrastructure and round-the-clock maintenance, we provide end-to-end support across three specialized tracks:
Custom Enterprise Application Development
Off-the-shelf software often can’t adapt as an organization grows. We architect applications on modern Microsoft foundations built for throughput, security, and integration with existing systems.
Cloud-native web applications
ASP.NET Core, Blazor, Angular, and React on microservices for independent scaling.
Cross-platform mobile apps
iOS, Android, and Windows from a single .NET MAUI codebase.
High-performance desktop systems
WPF and modern .NET runtimes, built from reusable component libraries.
Legacy Modernization & Azure Cloud Migration
Outdated stacks (VB6, classic ASP, older .NET Framework versions) slow teams down, introduce unpatched vulnerabilities, and run up infrastructure cost. Our migration framework is built for zero-data-loss upgrades with minimal cutover risk.
Framework upgrades
Direct migration to .NET 8 / .NET 9 for faster execution and native container support.
Azure cloud migration
Rehost, refactor, or rearchitect to Azure App Services, AKS, or Azure Functions, with CI/CD built in.
Database modernization
Migrate legacy SQL Server to Azure SQL Managed Instance or Cosmos DB.
Application Management Services (AMS) & 24/7 Support
Unplanned downtime has a direct cost. Our AMS teams provide continuous oversight, proactive patching, and rapid incident response for core business systems.
SLA-guaranteed incident management
Tier 1 to Tier 3 support, response times matched to business criticality.
Proactive performance and security audits
Real-time monitoring, SQL query tuning, and automated dependency patching.
Continuous enhancement and DevOps
Change requests, compliance updates, and release pipeline maintenance, no full internal team required.
Technical Discovery & Scope Request
The CHAMP Delivery Framework
Our five-stage delivery model, used across every engagement to keep risk and timelines predictable:
Consult & Assess
Code audits, infrastructure reviews, architecture planning.
Harmonize & Design
Wireframing, security compliance mapping, database architecture.
Accelerate & Build
Sprint-based engineering using pre-built .NET accelerators and automated QA.
Modernize & Deploy
CI/CD release automation, cloud provisioning, user acceptance testing.
Protect & Optimize
24/7 monitoring, SLA governance, continuous feature enhancement.

Frequently Asked Questions
How do you migrate applications from older .NET Framework versions to modern .NET?
We start with a codebase audit using Microsoft compatibility analyzers to map third-party dependencies, API deprecations, and architectural bottlenecks. From there we run a phased refactoring path to .NET 8 or .NET 9, with unit test coverage at each stage to confirm business logic hasn't changed.
What SLA tiers do you offer for Application Management Services?
We offer flexible support packages ranging from standard business-hours coverage to full 24/7/365 monitoring. Response times and escalation pathways are strictly tiered based on incident criticality (P1 to P4), ensuring your most mission-critical workloads receive immediate, prioritized resolution under customized SLA agreements.
Can your engineers work as an extension of our internal team?
Yes. We offer two models: fully managed project delivery, where Cetas owns the outcome end to end, and staff augmentation, where our certified .NET developers work inside your existing Jira or Azure DevOps workflows alongside your team.
What's the difference between Application Management Services and staff augmentation?
AMS is an outcome-based model: Cetas owns uptime, incident response, and SLA compliance for a defined system. Staff augmentation is a capacity model: our engineers join your team and work under your management and processes. Most clients start with one and add the other as needs shift.
