• Notifications and Alerts: Keep users updated with important information and events through timely notifications and alerts.
• Scalability: Design the application to handle workloads, regardless of the user base size efficiently.

Step 4: Organize the Cloud Application’s Architecture

Various ways to structure components in a cloud-based application depend on the project requirements. Below are the four most common types of cloud application architecture:

• Monolithic Architecture
  Monolithic architecture designs the application as a cohesive unit where all components are tightly connected and interdependent. This method is simple to develop but can be hard to scale and update.
• Microservices Architecture
  Microservices architecture divides the application into small, independent services, each with its own specific functionality, and they communicate through APIs. This model offers great flexibility and scalability but can be complex to manage and may have performance issues.
• Serverless Architecture (Function as a Service—FaaS)
  This architecture constructs the application using small, event-triggered functions in serverless environments. Serverless applications are cost-effective and adaptable but are not ideal for tasks that require extensive resources.
• Hybrid Cloud Architecture
  A hybrid cloud architecture merges on-premises infrastructure with public or private cloud resources. This setup provides high flexibility but can also face integration and security challenges.
