This document provides an overview and introduction to using the SAP HANA Cloud Persistence Service. It discusses how applications can access SAP HANA databases in the cloud using JDBC or JPA, and focuses on JPA as the preferred method. It demonstrates how to add persistence to applications using EclipseLink as the JPA implementation and includes steps for configuring applications to work with SAP HANA Cloud. The presentation concludes with reminders of related resources and a question/answer discussion section.

This lecture gives guidance on how you can use the features to build solutions that meet your security requirements. As a flexible and open cloud platform, does SAP HANA Cloud provide the rock-solid security required for your most sensitive data and applications? How do you authenticate and authorize users? How is your data isolated on SAP HANA Cloud and can you securely connect to your On-Premise systems? How do you secure access from mobile clients, and what if you want to have Single Sign-On (SSO) with other SAP Cloud solutions via SAP ID Service or your corporate user directory? At the end of each session, we will give some time for Q&A. Remarks: ■ The Virtual Bootcamp sessions are scheduled for the developers of our HANA Cloud Applications partners and the community interested in our HANA Cloud Applications partner program. ■ The sessions will be recorded and provided to our HANA Cloud Partner community.
- 17. Discussion / Q&A
- 18. © 2012 SAP AG. All rights reserved. 18 Questions & Answers Q: Where is HANA actually hosted - what latency between the Java application and HANA database one can expect? A: The HANA databases are located in the same data center as the applications (as can be seen on slide 13), so there is minimal latency between application and database. Q: Can different applications in the same account use different database types (HANA vs. non-HANA)? A: No, at present the configuration of the database type is on account level. Q: What is the roadmap for supporting that? A: By end of Q2/2013 it will be possible to specify the database type (HANA DB, Sybase ASE, MaxDB) as new parameter of the deployment. With that option it will be possible to assign each application to its own database type independently of the other applications in the same account.
