Introducing various common application architecture components and their evolution.

Hybrid cloud integrates a company’s internal IT resources with third-party cloud providers’ infrastructure and services.
AWS hybrid cloud services offer a consistent AWS experience from the cloud to on-premises to the edge, allowing you to store data and run applications across multiple environments.

In cloud services, enterprises use a large number of accounts, which causes fragmentation in architecture and security, increasing management difficulty.

Uploading the program to the Lambda service enables quick activation when network packets are sent in for request access, achieving a pay-as-you-go model.

As the “front door” for applications to access data, business logic, or functionality from backend services.
When using API Gateway, you can create RESTful APIs and WebSocket APIs to enable real-time bidirectional communication applications.
API Gateway supports containerized, serverless workloads, and web applications.

Point-in-Time Recovery (PITR) is a crucial data recovery feature for AWS DynamoDB and other database services.
It allows you to restore data to a previous state in case of accidental loss or corruption, ensuring business continuity.
PITR also enables regular data backups and retention of multiple versions, aiding in error tracking and resolution.
It’s flexibility in restoring data on demand without affecting other operations enhances system reliability and stability.
