What Is Serverless?
Serverless is a cloud computing model that runs code without server management. Code executes only when requests come in, and you pay only for what you use.
Advantages of Serverless
Cost Efficiency: Zero cost during idle timeAuto Scaling: Unlimited scaling based on trafficNo Operational Overhead: No server patching or scaling neededFast Deployment: Deploy code without infrastructure setupServerless Services
FaaS (Function as a Service)
AWS Lambda: Event-driven function executionAzure Functions: Supports various triggersGoogle Cloud Functions: GCP ecosystem integrationBaaS (Backend as a Service)
Supabase: PostgreSQL-based backendFirebase: Real-time DB, authentication, storageSuitable Use Cases
API backends (REST, GraphQL)Image/video processingIoT data processingScheduled batch jobsWebhook processingConsiderations
Cold Start: Initial execution delay (resolved with provisioned concurrency)Execution Time Limits: Not suitable for long-running tasksVendor Lock-In: Potential dependency on a specific cloud providerAdoption Benefits
When transitioning to serverless:
Infrastructure costs reduced by 60%Deployment time reduced by 70%Operations staff reduced by 50%Conclusion
Serverless is a cornerstone of cloud-native architecture. POLYGLOTSOFT supports serverless architecture design and migration.
