The next section we will cover is ECS Images. Images are a template of a runtime environment for an ECS Instance. There are 4 main types.
Public System Images: Public images licensed by Alibaba Cloud are highly secure and stable. These public images include most Windows Server and mainstream Linux systems. These images only include standard system environments and you can apply your own customization and configurations based on these images.
Marketplace Images: Alibaba Cloud Marketplace images are classified into the following 2 types. Images provided by Alibaba Cloud and Images provided by Independent Software Vendors and licensed by Alibaba Cloud Marketplace An Alibaba Cloud Marketplace image contains an operating system and pre-installed software. The operating system and pre-installed software are tested and verified by the ISV and Alibaba Cloud to ensure that the images are safe to use. These are suitable for website building, application development, and other personalized use scenarios.
Custom Image: Custom images are created from Instances or system snapshots, or imported from your local device. Only the creator of a custom image can use, share, copy, and delete the image. These custom images can be used to create more instances, saving you the effort of creating a new system from scratch.
Shared Image: A shared image is a custom image that has been shared to other users or accounts. Alibaba Cloud cannot guarantee the security and integrity of the images shared with you. You use them at your own risk and discretion.
