What is the function of elastic public IP?

An Elastic Public IP (EIP) is a static, public IPv4 address that can be dynamically bound to cloud instances. Its main function is to provide a fixed, public network access point for cloud resources, ensuring that these resources can be accessed from the internet.

Function:

• Static Public IP Address: Provides a stable public IP address that does not change even if the associated cloud instance is restarted or replaced.
• Dynamic Binding: Allows the EIP to be dynamically bound to different cloud instances, facilitating high availability and flexibility in managing network resources.
• Remote Access: Enables remote access to cloud instances for management, maintenance, and application access.
• Load Balancing: Can be used in conjunction with load balancers to distribute incoming traffic across multiple instances.

Example:

Imagine you have a web application running on a cloud instance. To ensure that users can access your application consistently, you can assign an EIP to this instance. Even if you need to scale your application by adding more instances or replacing the current one, the EIP remains the same, ensuring uninterrupted access for your users.
