Lesson Overview
In this lesson, you'll learn how to add an SAP HANA Cloud, data lake instance to an excising SAP HANA database instance already deployed in your SAP BTP account.
Adding an Integrated Data Lake
As a database administrator, you want to deploy an SAP HANA Cloud, data lake instance attached to the SAP HANA Cloud, SAP HANA database that is already used in the SAP BTP as this is the most cost efficient method. Your BI modeling colleagues will use this data lake to learn how they can build their analytic reports.
Caution
The following video shows a business case for adding an integrated Data Lake.
Add an Integrated Data Lake
The demonstration "Adding a Data Lake to an SAP HANA Cloud Instance", shows the all the required steps to add a data lake to an SAP HANA Cloud database instance.
The SAP HANA Cloud Central allows you to add an integrated data lake to an existing SAP HANA Cloud database instance. Select the °°° (more) button of the SAP HANA Cloud database instance to view the possible actions you can perform on the database. Choose the Add Data Lake option to start the provisioning wizard to add a data lake.
In the provisioning wizard, you need to specify the data lake instance name and description in the Basics area. You must also enter and confirm a strong password for the HDLADMIN user.
Note
In the Size area of the input screen, you can specify the number of vCPUs for the Coordinators and Workers nodes. The minimal required number of vCPUs is calculated from the storage size. In the trial account, the storage size is fixed, so you have to accept the given number of vCPUs.
In the Connections area, you specify which IP addresses are allowed to connect to your data lake instance. Depending on your need, you keep the connections local to the SAP BTP, or only specific IP addresses and ranges of your company or all IP addresses.
Caution
In the Backup area, you specify if automatic database backup feature needs to be enabled.
By default the provisioning wizard configures and schedules data lake backups. You can manually disable this feature if no backups are required.
Customer Controlled Key Management
The Encryption Key Management Service is also available for SAP HANA data lake. This allows you to use the customer-controlled encryption key (CCEK) feature for integration with the SAP Data Custodian Key Management Service (KMS).
