Description: An ephemeral disk is a type of temporary storage that is directly associated with a virtual machine instance in cloud computing environments. This type of disk is automatically created when the instance starts and is destroyed when the instance is shut down or deleted. Ephemeral disks are ideal for storing temporary data that does not need to be persistent, such as cache files, intermediate processing data, or any information that does not require long-term storage. Unlike persistent disks, which can be used to store data continuously and can be attached to different instances, ephemeral disks are faster and offer superior performance due to their proximity to the instance’s CPU. However, their volatile nature means that any data stored on them will be lost when the instance is terminated, making them less suitable for applications that require high data availability. In summary, ephemeral disks are an efficient and high-performance solution for temporary storage needs in cloud computing environments.
