Serverless Architecture Explained | AWS Lambda & API Gateway | DevOps Class 23

Welcome to FusionPact DevOps Daily Classes – Class 23 🚀 In this session, we explain Serverless Architecture using AWS Lambda, one of the most powerful cloud-native approaches that allows teams to build applications without managing servers. You’ll learn what serverless really means, how AWS Lambda works behind the scenes, how API Gateway triggers Lambda functions, and how real-world applications like user signup systems are built using serverless architecture. This class is ideal for DevOps engineers, cloud engineers, and backend developers who want scalable, cost-effective, and low-maintenance cloud solutions. 📌 What You’ll Learn in DevOps Class 23 What is Serverless Architecture Why serverless does NOT mean “no servers” How AWS Lambda works Event-driven execution model AWS Lambda + API Gateway architecture Pay-per-execution pricing model Real-world serverless example (User Signup Flow) Benefits of serverless over EC2-based systems ☁️ What Is Serverless Architecture? Serverless architecture means developers do not manage servers. The servers still exist, but AWS handles: Server provisioning Scaling Maintenance Availability Developers focus only on writing business logic, not infrastructure. ⚙️ How AWS Lambda Works AWS Lambda executes code only when an event occurs. Events can be: API requests File uploads Database changes Scheduled triggers When the event happens: Lambda starts automatically Code runs Execution stops You pay only for execution time There are no always-running servers, unlike EC2. 🔗 Serverless Architecture Flow (AWS) User sends request API Gateway receives request API Gateway triggers Lambda function Lambda processes data Lambda interacts with database (if needed) Response is sent back to user This happens automatically at scale. 🧪 Real-World Example – User Signup Application User fills signup form API Gateway receives request Lambda function validates user details Data is stored in database Lambda returns success or failure message Even if thousands of users sign up at the same time, AWS Lambda scales automatically without any manual effort. 💰 Cost & Scaling Benefits No server start/stop management Automatic scaling Pay only for execution time Ideal for unpredictable workloads Reduced operational overhead 🎯 Key Benefits of Serverless Architecture Zero server management Automatic scaling Low operational cost Faster development High availability Ideal for microservices & APIs 🧠 Key Takeaways Serverless simplifies cloud application development AWS Lambda runs code only when needed API Gateway connects users to Lambda Cost-effective and scalable by default Perfect for modern DevOps architectures 🔔 Subscribe for Daily DevOps Classes by FusionPact 📘 Learn real-world DevOps & Cloud concepts step-by-step 🌐 Fusionpact Skills • Trust • Impact #serverless #awslambda #devopsengineering #devopsdaily #cloudcomputing #FusionPact #aws
