Create simple application servers | Purchase plans provided in the Chinese mainland | If you run your business in the Chinese mainland or your customers locate in the Chinese mainland, you can purchase plans available in Chinese mainland regions. This ensures high-speed and stable user access over the Internet. | |
Purchase plans provided outside the Chinese mainland | If you run your business outside the Chinese mainland or your customers locate outside the Chinese mainland, you can purchase plans available in non-Chinese mainland regions If you run your business in the Chinese mainland or your customers locate in the Chinese mainland, we do not recommend you to purchase plans available in non-Chinese mainland regions. Because these plans result in increased access latency, which brings unfulfilled user experience. For example, if you run your business in Hong Kong or Southeast Asia, you can purchase plans available in regions such as China (Hong Kong) and Singapore. | ||
Connect to simple application servers | Remotely connect to Linux servers | You can connect to a Linux simple application server by using the Simple Application Server console or a third-party client. | |
Remotely connect to Windows servers | You can connect to a Windows simple application server by using the Simple Application Server console or Remote Desktop Connection. | ||
Connect to a Linux server by using the rescue feature | If you cannot remotely connect to your Linux server because Secure Shell (SSH) configurations are modified or due to some other reasons, you can use the rescue feature provided by Simple Application Server to temporarily log on to the server for troubleshooting. | ||
Manage simple application servers | Manage server lifecycles | The lifecycle of a simple application server spans from creation to release of the server. Throughout the course of the process, the simple application server undergoes a variety of states. | |
View server information | After you create a simple application server, you can view its details such as the configurations, expiration time, and resource usage in the Simple Application Server console. | ||
Change server names | You can change server names to distinguish and manage servers in a straightforward style. | ||
Release servers | You can manually release simple application servers that expire or are no longer required. You can also wait for Simple Application Server to release these servers. | ||
Manage passwords and keys | Set or reset server passwords | If you want to use a username and password to connect to a simple application server, you can set a logon password for the server. If you forget the logon password of a simple application server, you can reset a logon password for the server. | |
Create and replace key pairs for Linux servers | Alibaba Cloud provides the secure and convenient SSH key pair-based authentication method for logons to simple application servers. The key pairs are used for authentication and encrypted communication over the SSH protocol. A key pair consists of a public key and a private key. Only Linux simple application servers support SSH key pair-based authentication for logons. If you have high requirements on security and convenience, you can create an SSH key pair for your simple application server. | Create and replace key pairs for Linux simple application servers | |
Manage applications | Manage applications | After you create a simple application server based on an application image, you can view preset applications in the application image and manage the applications based on the usage procedure provided in the Simple Application Server console. | Manage applications on a server that is created based on an application image |
Manage domain names | Resolve and bind domain names | Although your customers can access your website built on a simple application server by using a public IP address, we still recommend that you configure a domain name for your website. This ensures the security of your website and facilitates more effortless user access. | |
Manage firewalls | Manage firewalls | The firewall of a simple application server is a virtual firewall that uses firewall rules to control the inbound traffic of the simple application server. This ensures the security of the server. | |
Manage data disks | View data disks | If you attach a data disk to your simple application server, you can view details of the data disk such as the size, mount path, and status in the Simple Application Server console. | |
Attach a data disk | You can attach a data disk to your simple application server when or after you create the simple application server. | ||
Partition and format a data disk | After you attach a data disk to your simple application server, you must partition and format the data disk before you can use it. | ||
Scale up a data disk | You can scale up a data disk if the available space of the data disk on your simple application server is insufficient to meet your business requirements. | ||
Manage snapshots | Manage snapshots | A snapshot is a point-in-time backup of a disk. Snapshots can be used to back up data, recover data after misoperations on servers, recover data after network attacks, and create custom images. | |
Manage custom images | Create custom images | You can create custom images to store the data on a simple application server. | |
Share custom images | You can share custom images from Simple Application Server to only Elastic Compute Service (ECS). If the configurations of your simple application server cannot meet your business requirements, or you want to deploy your business on ECS instances, you can share your custom images to ECS to transfer your business from Simple Application Server to ECS. | ||
Unshare custom images | You can unshare custom images based on your business requirements. You must unshare custom images before you can delete them. | ||
Copy custom images | You can copy custom images from one region to another region and then use the copies of the custom images to create simple application servers. This way, you can seamlessly migrate data between simple application servers across regions. You can also use the custom image sharing feature to share the copies of the custom images to ECS. Then, you can use the shared image copies to create ECS instances. This way, you can seamlessly migrate data from simple application servers to ECS instances across regions. | ||
Delete custom images | You can delete custom images that are no longer required. | ||
Create servers based on custom images | You can use custom images to create simple application servers that have the same configurations as or higher configurations than the custom images. | Use a custom image to create one or more simple application servers | |
Copy images shared by Simple Application Server in the ECS console | We recommend that you copy custom images shared by Simple Application Server in the ECS console before you use the custom images to create ECS instances or replace OSs. You must save the copies on ECS to prevent data loss. | Copy an image shared by Simple Application Server in the ECS console | |
Manage service interconnection | Enable service interconnection | Simple application servers are automatically assigned to virtual private clouds (VPCs), which isolate the servers from other Alibaba Cloud services. By default, simple application servers are not interconnected with other Alibaba Cloud services such as ECS and ApsaraDB. The service interconnection feature allows simple application servers to interconnect with other Alibaba Cloud services over VPCs. | |
Upgrade simple application servers | Upgrade simple application servers | As your business develops, existing simple application servers may not be able to meet your business requirements. In this case, you can update the simple application servers. | |
Reset OSs | Reset OSs | You can install new applications or OS on a simple application server by resetting the OS of the server. | |
