.NET App Modernization: 6 Week Implementation

Our .NET Centre of Excellence and our esteemed Microsoft Specialisation in Modernizing Enterprise Applications, highlights our dedication to meeting the rigorous requirements of the Microsoft Cloud Adoption Framework - to offer the absolute best possible service and experience to you.

Our Migration & Modernization strategies include:

• Re-host: Migrate to a different platform without changes. No changes to the existing application.
• Re-platform: Move to a new platform with minimal changes. If the application uses older .NET versions, you might consider upgrading to the latest .NET Core or .NET 5+ versions.
• Re-factor: Rework or rewrite parts of the application. Refactor the App for true PaaS compatability e.g. with Container services with minimal changes to code.
• Re-architect: Redesign the application's architecture. For complex applications, especially those originally built as monoliths, breaking them down into microservices can be beneficial for scalability and maintainability.
• Rebuild: Completely rewrite the application. Especially useful if new requirements to cater for changing business needs.
• Replace: Substitute with a modern off-the-shelf solution.

PROCESS OVERVIEW

Stage 1: Modernization Assessment & Design

What We Do: The application modernisation assessment process is a structured 8-step approach that begins with data gathering and inventorying. Intelligent tools are used to catalog and categorise applications, assessing their usage patterns, technology stacks, and relevance to different business units. This is followed by filtering redundant or outdated applications and using AI-powered tools for deep analysis, pinpointing performance bottlenecks and interdependencies. Engaging with stakeholders through interviews, the needs and challenges are captured, which helps in prioritising applications based on various criteria like business criticality, user engagement, and potential for modern improvements. Following this prioritisation, a pilot phase is initiated by selecting a diverse subset of applications to test modernisation strategies, ensuring their effectiveness and refining the approach as needed. The insights, findings, and recommendations are thoroughly documented, culminating in a comprehensive phased roadmap that charts out the journey for modernising the entire application portfolio. The design and planning phase for the selected in-scope applications, addresses architecture, scalability and security and selects the best modernisation approach such as Azure App Service, Container Apps and maps out DevOps practices.

What You Get:

• Assessment Summary
• Modernisation Strategy & Recommendations
• Phased Roadmap for your unique modernisation journey

Stage 2: Modernization PoC

The next step is preparing and implementing the application for Modernization. This includes:

• Setting up of the Environment: A dedicated Azure environment as your production environment, along with deployment checklists, testing and security assessments.
• Modernization Implementation: Configuring the Azure Container architecture & refactor of the application, implementing DevOps and Security. Conducting regression testing and performance testing.
• Validation of Business Benefits: Review cost/benefit (RoI & TCO). Submit the Application for user testing and feedback.

Stage 3: Post Modernization Cloud-Support-Services

The App can be either transitioned back to your IT team, Supported by OpenSky's dedicated support team or a Hybrid scenario.

• Transition to in-house IT: Conduct knowledge transfer to your IT team
• OpenSky Support: OpenSky's .NET Centre of Excellence is a hub of collaborative expertise encompassing a range of professionals - from certified developers who turn concepts into efficient, high-performing applications, to project managers who ensure timely and smooth project execution, achieving a 98% average SLA response rate. Our meticulous QA teams uphold rigorous standards, maintaining our ISO 20000, ISO 27001, and ISO 9001 accreditations, ensuring the highest quality outputs, while our data scientists harness advanced analytics to enhance .NET solutions' efficiency and innovation. Additionally, our business analysts bridge technical and business worlds, ensuring tailored solutions aligned with strategic objectives. This collective synergy drives unparalleled innovation and makes OpenSky a trusted name in .NET development.

Our Modernization PoC is priced at refactoring using Containers and is subject to scoping depending on actual application migration scenario to validate the pricing model.
