Network Programmability: What is APIs, REST, automation and programmability

1. APIs (Application Programming Interfaces)
   APIs are sets of protocols, routines, and tools that allow different software applications to communicate with each other. They define the methods and data formats that a software component should use to communicate with other components. APIs enable the integration of different software systems and allow developers to build new applications using existing functionality.

2. REST (Representational State Transfer)
   REST however, is an architectural style for designing networked applications. It is often used for building web services, and it relies on a stateless client-server communication model.

   RESTful APIs use HTTP methods (GET, POST, PUT, DELETE, etc.) to perform or and run CRUD (Create, Read, Update, Delete) operations on resources. RESTful APIs are easy to use, scalable, and widely supported by various programming languages and frameworks.

3. Automation
   Automation refers to the use of software tools and technologies to automate repetitive tasks, processes, or workflows. In the context of network programmability, automation involves using APIs, scripts, and other tools to automate network configuration, management, and monitoring tasks.

   Automation can help reduce human error, improve efficiency, and enable network teams to focus on more strategic tasks.

4. Programmability
   Programmability refers to the ability to control and manage network devices and systems using software. Network programmability involves using APIs, scripts, and other software tools to automate network configuration, management, and monitoring tasks.

   Programmable networks are more flexible, agile, and responsive to changing business needs. They enable network teams to automate routine tasks, accelerate service delivery, and improve network performance and security.

In summary, APIs, REST, automation, and programmability are closely related concepts that are essential for building modern, agile, and programmable networks.

APIs provide a standardized way for software components to communicate with each other, while RESTful APIs enable the creation of scalable and easy-to-use web services.

Automation and programmability enable network teams to automate routine tasks, reduce human error, and improve network performance, security, and agility.
