Building a Cloud Migration Strategy with Blazor and Azure

Why Cloud, Why Now?

Technology moves fast, but business decisions need to be even faster. Maintaining on-premises infrastructure is costly and can limit business agility. Meanwhile, cloud platforms like Microsoft Azure offer scalability, security, and cost optimization that are difficult to match with traditional IT environments.

But let's get specific. What if your organization has legacy applications that are critical to operations but need modernization?

Enter Azure and Blazor,  a dynamic duo that can modernize your applications while maintaining familiar development patterns. Whether you’re considering migration for cost efficiency, performance, or future-proofing, moving to Microsoft Azure gives you flexibility, scalability, and global reach with minimal operational overhead. And if you’re already leveraging .NET technologies, Blazor provides a seamless way to transition your applications to the web without completely rewriting your codebase.

In this post, we’ll explore how to migrate applications to Azure, why Blazor makes sense for modernization, and what business leaders should consider when planning their cloud transition.

Why Blazor? A Perspective on Modernizing Legacy Apps

Many organizations still rely on desktop applications in their business. These applications may be running critical business functions but are becoming more difficult to maintain, costly to support, and increasingly lack compatibility with modern security and performance expectations.

Blazor offers a compelling solution by allowing organizations to:

• Leverage existing .NET skills – Your development team doesn’t need to learn JavaScript-heavy frameworks. Blazor allows them to build interactive web apps using C# and .NET.
• Extend desktop applications to the web:  Blazor makes it easier to migrate thick-client applications into browser-based apps without losing functionality.
• Future-proof investments: As part of the .NET ecosystem, Blazor benefits from long-term Microsoft support and cloud-native capabilities through Azure.
• Optimize costs with cloud scalability: Unlike traditional desktop apps, Blazor applications deployed to Azure can scale dynamically based on user demand.

For CIOs considering application modernization, Blazor provides a lower-risk, high-reward migration path that balances modernization efforts with operational continuity.

Why Azure?

Migrating applications to Azure is a great approach to align IT strategy with business goals.

1. Scalability & Performance

With global Azure data centers, your app can be deployed closer to users, ensuring low latency and high performance. Need more power? Just scale up or scale out with a few clicks.

2. Security & Compliance

Azure includes built-in DDoS protection, identity management (Azure AD), and compliance certifications (HIPAA, GDPR, etc.)—critical for data-sensitive industries.

3. Cost Optimization

Unlike on-prem environments that require heavy upfront investments, Azure offers pay-as-you-go pricing with auto-scaling to optimize cloud spend.

Cost Control Example: You can set budgets and spending limits in Azure, ensuring you only pay for what you use.

4. Business Agility & Innovation

With Azure, your IT team can focus on building new features instead of maintaining servers. DevOps automation, AI/ML capabilities, and analytics tools help businesses move faster than ever.

Migrating to Azure: A Practical Roadmap

Once you’ve decided to modernize, the next step is planning your migration to Azure. Here’s a strategic approach to ensure a smooth transition.

1. Assess Your Current Application & Infrastructure

Before migrating, evaluate your existing application:

• What’s the architecture? Is it monolithic, client-server, or web-based?
• What are the dependencies? Legacy databases, third-party libraries, or authentication services?
• How will users be affected? Will workflows change? Are there compliance concerns?

2. Choose the Right Azure Services

Microsoft Azure offers multiple ways to deploy and scale your Blazor applications. Some key services include:

Azure App Service (Best for most Blazor apps)

• Fully managed PaaS (Platform-as-a-Service) solution
• Built-in scaling, security, and monitoring
• Supports Windows or Linux hosting

Azure Virtual Machines (VMs)

• More control over the environment (for complex, legacy workloads)
• Requires manual updates and scaling

Azure Kubernetes Service (AKS)

• Best for microservices-based architectures
• Enables containerized deployments

3. Deploying a Blazor Application to Azure

Once your Blazor app is ready, deployment is straightforward. Jeff Fritz, a Microsoft technical influencer, outlines the steps to publish a Blazor app to Azure using Visual Studio:

1. Open your project in Visual Studio
2. Go to Publish settings and choose Azure App Service
3. Select a hosting plan (e.g., B2 instance with 2 CPU cores, 3.5GB RAM)
4. Set up a resource group and region (e.g., East US2 for low latency)
5. Click "Publish": Your Blazor app is live on Azure!

From there, you can scale up or out dynamically based on traffic demands—all without adding new hardware. Watch the video below!
