What is Backend Development?

  • Definition: Backend developers create server-side software that powers websites/applications.
  • Primary Responsibilities:
    • Server-Side Logic: Writing code that runs on web servers, handling business logic, processing user requests, and managing data flow.
    • Database Management: Designing, implementing, and maintaining databases, ensuring data integrity and security.
    • API Development: Creating APIs for communication between different software applications.
    • Server Management: Configuring and managing servers, including cloud-based resources.
    • Security: Protecting against cyber threats, securing data, and implementing authentication/authorization.
