Lesson 3: Cloud-Native Architecture

What is Cloud-Native?

Cloud-native architecture is a design methodology that uses cloud services to build and run scalable applications in modern, dynamic environments. These applications are built from the ground up to capitalize on the elasticity and distributed nature of the cloud.

Microservices Architecture

Instead of building a single, monolithic application, a microservices architecture breaks down the application into small, independent services that communicate over well-defined APIs.

• Benefits: Independent deployment, scalable components, flexibility in technology choices.
• Challenges: Complex communication, distributed tracing, and data management.

Containers and Orchestration

Containers offer a logical packaging mechanism in which applications can be abstracted from the environment in which they actually run. Orchestration tools (like Kubernetes) manage the lifecycle of these containers, handling deployment, scaling, and networking.

Serverless Computing

Serverless computing allows you to build and run applications and services without thinking about servers.

• You do not provision, scale, or manage any servers.
• You pay only for the compute time you consume.
• Examples include AWS Lambda, Google Cloud Functions, and Azure Functions.
