Deployment Modes

Figure 1 shows the deployment scheme of the SAP Business One.

Figure 1 SAP Business One deployment scheme

The concepts involved in the preceding figures are as follows:

VPC network: All nodes in the SAP Business One system are deployed within a VPC network and belong to the same AZ to ensure network security.
Public subnet:
- A NAT ECS allows you to access SAP Business One nodes using SSH.
- An SAP HANA Studio ECS is an ECS running the SAP HANA Studio software. You can use the Remote Desktop Protocol (RDP) or SSH to access the SAP HANA Studio ECS and manage the SAP HANA database.
Private subnet:
An SAP HANA and SAP Business One ECS is used to deploy the SAP HANA database and SAP Business One (SAP HANA version). The ECS has the following disks attached:
- OS disk: provides the directory for installing the OS.
- Data volume: periodically stores the data transmitted from the SAP HANA IMDB (a database running in high-performance memory). The period is 5 minutes by default.
- Log volume: stores the data triggered by an event. When an event, for example, a record or a batch of records are updated, is triggered for the server IMDB, the system will write the latest IMDB data into the log volume.
- Shared volume: stores the SAP HANA installation software and SAP HANA database log files.
- Backup volume: stores SAP HANA database backup files. The backup volume is provided by SFS in this document.
An SAP Business One Client ECS is used to install the SAP Business One (SAP HANA version) client.
