An Elastic IP (EIP) is a static, public IPv4 address that can be dynamically allocated to cloud instances. It allows for flexible management of IP addresses, enabling users to quickly reassign them to different instances in case of failure or the need for scaling. This is particularly useful in maintaining service continuity and high availability.
For example, if an instance running a critical application fails, you can quickly assign its Elastic IP to a new instance, minimizing downtime and ensuring that your service remains accessible from the internet.
In the context of cloud services, platforms like Tencent Cloud offer Elastic IP services. With Tencent Cloud, you can easily allocate and manage Elastic IPs through their console or APIs, facilitating efficient resource management and enhancing the reliability of your applications.
