Serverless .NET with Azure Functions — Simplify, Scale & Save!

Serverless .NET with Azure Functions — Simplify, Scale & Save!

Article by:  Radhakrishnan A

 Tired of managing servers, scaling infrastructure, or worrying about uptime?

Serverless computing is here to change the game — and Azure Functions makes it effortless for .NET developers.


What is Azure Functions?
Azure Functions lets you run small pieces of code — functions — without managing servers.
 Write your logic, deploy, and let Azure handle the rest — scaling automatically based on demand.
Think of it as “code that runs only when needed” — perfect for:
Background jobs
APIs
Webhooks
Integrations

Why It’s Powerful for .NET Developers
✔ Write in C#, F#, or any .NET language
 ✔ Pay only for execution time — no idle costs
 ✔ Seamless integration with Azure services (Storage, Cosmos DB, Event Grid, etc.)
 ✔ Auto-scales with zero configuration
 ✔ Local debugging & deployment via Visual Studio or Azure CLI

Common Use Cases
✔ Send emails or notifications after an event
 ✔ Process background tasks (image resize, queue handling)
 ✔ Trigger workflows via HTTP requests, timers, or service bus messages
 ✔ Build real-time data pipelines or serverless APIs

How It Works (Simplified)
1️⃣ Trigger — Function starts on an event (HTTP request, timer, queue message)
 2️⃣ Function Code — Define your logic (e.g., save data, send email)
 3️⃣ Binding — Input/output bindings connect storage, queues, or databases effortlessly
 4️⃣ Execution — Azure runs your code on demand and scales automatically

✨ Pro Tips for Success
✔ Keep functions small & focused (Single Responsibility Principle)
 ✔ Use Dependency Injection for cleaner architecture
 ✔ Log everything — Application Insights works beautifully
 ✔ Version your functions for safe updates

🔑 Key Takeaway
Serverless .NET isn’t just about saving infrastructure effort — it’s about:
 ✅ Building faster
 ✅ Scaling smarter
 ✅ Focusing on business logic, not servers

Performance Optimization in Sitecore

  Performance Optimization in Sitecore Caching Strategies Implementing caching properly in Sitecore significantly improves performance. The following caching techniques should be used:   HTML Caching Ø   Store rendered HTML output to reduce processing time. Ø   Enable caching on Sitecore renderings (Caching tab in Sitecore Experience Editor). Ø   Configure vary by parameters to cache different versions of content. Data Caching Ø   Use Sitecore’s Data Cache to store frequently accessed database queries. Ø   Implement custom memory caches using .NET MemoryCache for high-frequency data. Ø   Leverage pre-fetch caching to load important content in advance. Output Caching Ø   Store entire page outputs in the cache for quick retrieval. Ø   Configure Sitecore Output Cache settings at the item level. Ø   Set cache expiration rules to balance freshness and performance.   Load Balancing & Database Optimiz...

Strategies for Migrating to Sitecore from legacy or upgrading from older Sitecore

  Migration Migrating to Sitecore from legacy CMS platforms (Adobe AEM, WordPress, Drupal) or upgrading from older Sitecore versions requires a well-planned strategy .   How do you handle Sitecore upgrades and migrations? Assess Current Version – Identify the existing Sitecore version and compatibility requirements. Backup & Staging Setup – Create database and content backups , and deploy to a staging environment for testing. Upgrade in Phases – If migrating from older versions, use incremental upgrades instead of direct major jumps. Resolve Breaking Changes – Address deprecated APIs, custom pipelines, and config updates . Test Extensively – Perform functional testing, regression testing, and performance validation before go-live.   Planning a Sitecore Migration Before migration, organizations must: Assess Existing Content & Workflows – Identify outdated content and a...

Azure Event Grid Sample code

  Event Grid Azure Event Grid is a fully managed event routing service that enables event-driven architectures by: •                Delivering events from sources to subscribers in near real-time. •                Supporting fan-out (sending the same event to multiple subscribers). •                Ensuring high reliability and scalability. How Event Grid Fits in SOA Decoupling Services: SOA often involves tightly coupled services that rely on synchronous communication (e.g., REST or SOAP APIs). Event Grid enables asynchronous communication by routing events between services, reducing coupling and improving scalability. Event-Driven Communication: Instead of services polling for updates or making direct API calls, they can react to events published to Event ...
