A right mouse click on Servers allows to register a new database server to Database Studio, the context menu on a server name allows to register databases which are installed on this server.
In the list of databases you can select which should be added to the Database Studio.
In the simple installation mode only a few database parameters have to be set. The database is installed with one data and one log volume. In the advanced mode all parameters can be set and any number of volumes can be configured.
To be able to restore a backup during the installation process, the advanced mode is required. In the next step specify on which server the database should be installed and how it is called. If you install the database on the same server on which the Database Studio is running, you don't have to enter a Database Server.
This is the user used to connect with the Database Studio to the database. As this user is essential to administer the database, make sure to remember its password!
These features can also be activated after the database has been installed. The database parameters can either be initialized with default values, can be copied from from another database instance or restored from a data backup.
Whenever you change a parameter value, it is recommended to enter a comment that you can check later on why a specific parameter has been changed e.

To do so simply double-click an entry in the list. If an empty database should be installed, you have to specify the Database System Administrator. This user is the first SQL user and the owner of the system tables. If you want to set up a standby instance, you have to choose the second option — Create database for recovery.
In this case the Database System Administrator is taken from the backup — as well as all other SQL users and all data. You have to know the user name and password specified in the source database for this user!
At the last step, you can either load the tutorial data, active overwrite mode for the log or enable the automatic saving of the log. Both latter options will enable you to avoid a possible logfull situation.
For productive environments, we either recommend to regularly save the log manually, or switch on the automatic saving of the log. Choose Back to correct any settings. While using the system, users can create or delete user accounts as required by the operating system. It is logically isolated from other virtual networks in Alibaba Cloud.
You have full control over your Alibaba Cloud VPC, for example, you can select its IP address range, further segment your VPC into subnets, as well as configure route tables and network gateways. Additionally, you can connect your VPC with your on-premises network using a physical connection or a VPN to form an on-demand customizable network environment. This allows you to smoothly migrate your applications to Alibaba Cloud with little effort.

Security isolation By default, the cloud servers of different users are located in the different VPCs. Different cloud servers in the same subnet use the VSwitch to communicate with each other, while cloud servers in different subnets within a VPC use VRouters to communicate with each other.
Because the IP packets of cloud servers are encapsulated with the tunneling ID, the data link layer two-layer MAC address of the cloud server will not transfer to the physical network.
Therefore, the two-layer network of different cloud servers is isolated. In another word, the two-layer networks between different VPCs are isolated.
This is the third layer isolation.
It is important to note that you cannot connect to a fully internal VM instance directly by using SSH. To connect to such internal machines, you must set up a bastion instance that has an external IP address and then tunnel through it. You can provision VMs in your network to act as trusted relays for inbound connections, called bastion hosts, or network egress, called NAT gateways.
For more transparent connectivity without setting up such connections, you can use a managed VPN gateway resource.
Security Groups A security group is a logical group that groups instances in the same region with the same security requirements and mutual trust. This is the third layer isolation.

Security Groups A security group is a logical group that groups instances in the same region with the same security requirements and mutual trust. Each instance belongs to at least one security group, which must be specified at the time of creation. Instances in the same security group can communicate through the network, but instances in different security groups by default cannot communicate through an intranet.
However, mutual access can be authorized between two security groups. A security group is a virtual firewall that provides stateful packet inspection SPI. Security groups are used to set network access control for one or more ECSs. As an important means of security isolation, security groups are used to divide security domains on the cloud. Create and configure a specific security group, which only allows the required inbound and outbound access to the SAP support network, for the SAProuter instance, along with TCP port Set up the connection with SAP.
Security For an IaaS deployment and SAP MaxDB system implement, Alibaba Cloud maintains security of the infrastructure that supports the cloud, and the customer is responsible for ensuring the security of the cloud resources and applications, which the customer uses. Resource Access Management Alibaba Cloud Resource Access Management RAM is an identity and access control service, which enables you to centrally manage your users including employees, systems or applications and securely control their access to your resources through permission levels.The rundirectory e.

There is nothing left to be done. This means that you are free to choose the platform that suits best: to your business needs and to your budget. One can choose the degree of automation e. The DBAnalyzer to collect and evaluate monitoring data to find bottlenecks is also integrated to Database Studio.
There are many benefits to store backups in Alibaba Cloud OSS compared to tape, such as you can read, write, delete and store unlimited objects in your OSS bucket; OSS stores three copies of your objects in multiple locations to ensure
