Create simple application servers

Purchase plans provided in the Chinese mainland

If your business or customers are located in the Chinese mainland, you can purchase plans provided for the regions in Chinese mainland. This ensures high-speed and stable Internet access.

Purchase plans provided for regions outside the Chinese mainland

If your business or customers are located outside the Chinese mainland, you can purchase plans provided for regions outside the Chinese mainland. We do not recommend that you purchase these plans if your business or customers are located in the Chinese mainland to prevent high latency. For example, if your business or customers are located in the Hong Kong or Southeast Asia, you can purchase plans for the China (Hong Kong) or Singapore region.

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 tool.

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 connect to your Linux server because SSH configurations are modified or due to some other reasons, you can use the rescue feature in the Simple Application Server console to temporarily log on to the server and then fix issues.

Manage simple application servers

Manage server lifecycles

The lifecycle of a simple application server spans from creation to release of the server. During the process, the simple application server transits different status.

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 the names of simple application servers to distinguish and manage the servers in a straightforward style.

Release servers

You can manually release simple application servers that expire or are no longer needed. You can also wait for the system to release the 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, you can reset a logon password.

Create and replace key pairs for Linux servers

Alibaba Cloud provides the secure and convenient SSH key pair-based authentication method for logon 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 logon authentication. If you have high requirements on security and convenience, you can create an SSH key pair for your simple application server.

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 domain names

Bind and resolve domain names

Although your customers can access your website built on a simple application server by using the public IP address of the server, we still recommend that you configure a domain name for your website. This ensures the security of your website and facilitates 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 mount 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.

Mount a data disk

You can mount 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 the data disk if the available space of the data disk on your simple application server cannot 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 a custom image to store the data on a simple application server.

Share custom images

You can share custom images from Simple Application Server to Elastic Compute Service (ECS). If the configurations of your simple application server cannot meet your business requirements or you want to use ECS to deploy your business, you can share your custom image with ECS to migrate your business from Simple Application Server to ECS.

Unshare custom images

You can unshare a custom image based on your business requirements. You must unshare a custom image before you can delete it.

Copy custom images

You can copy a custom image from one region to another and use the copy of the custom image to create simple application servers in the destination region. This implements seamless migration of simple application servers across regions. You can also use the custom image sharing feature to share the copy of the custom image to ECS. Then, you can use the shared image to create ECS instances. This way, you can seamlessly migrate your business from simple application servers to ECS instances across regions.

Delete a custom image

You can delete custom images that are no longer needed.

Create servers based on custom images

You can create simple application servers that have the same or higher configurations based on a custom image.

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 operating systems. You must save the copies on ECS to prevent data loss.

Upgrade simple application servers

Upgrade simple application servers

If the specifications of your simple application server do not meet your business requirements, you can upgrade the simple application server.

Reset OSs

Reset OSs

You can install new applications or an OS on a simple application server by resetting the server. This re-initializes the server.

Maintain and monitor servers

View the monitoring information of servers

You can view the monitoring information of a simple application server, such as the data transfers, vCPUs, memory, and system disk. This way, you can understand the resource usage of the server and improve O&M efficiency.

View the operation records of servers

On the Operation Records page of a simple application server, you can view the historical operation records of the server, including starting the server, stopping the server, restarting the server, changing the server password, and resetting the OS of the server. You can use these operation records to analyze and troubleshoot issues.

Enable Command Assistant

Command Assistant is an automated O&M tool for Simple Application Server. You can manage simple application servers by using shell, PowerShell, and batch commands in the Simple Application Server console without logging on to the servers.

• Create commands
• Run a command
• Upload files to simple application servers
