System Architecture.

From Monoliths to Microservices. Understand how modern systems are designed for scale.

Evolution of Scale

Legacy systems were built as single, massive codebases (Monoliths). Modern cloud-native apps are broken down into small, independent services (Microservices) that communicate via APIs. This enables independent scaling, deployment, and fault isolation.

Decoupled components for agility
Independent scaling of bottlenecks
Fault isolation (blast radius reduction)
Polyglot persistence & programming

Why Containers?

Consistency: Works on my machine = Works in production.
Isolation: Apps don't conflict with each other.
Efficiency: Share the OS kernel, unlike VMs.

Orchestration at Scale.

Manage thousands of containers with Kubernetes. Auto-scaling, self-healing, and zero-downtime deployments.

Serverless Computing.

Focus on code, not servers. Event-driven architecture with AWS Lambda.

Pay Per Invocation

Serverless allows you to run code without provisioning or managing servers. You pay only for the compute time you consume. Ideal for event-driven workloads, REST APIs, and data processing.
