3 Architecture and Deployment Scenarios
Techniques You’ll Master- Understand in-memory technologies and how SAP HANA
uses them - Get to know the internal architecture of SAP HANA
- Describe the SAP HANA persistence layer
- Learn the different ways that SAP HANA can be deployed
- Know when to use different deployment methods
In this chapter, you’ll become familiar with the various deployment scenarios for SAP HANA and evaluate appropriate system configurations, including cloud deployments. We’ll provide an introduction to the new in-memory paradigm and the thinking behind how SAP HANA uses in-memory technologies. By the end, you’ll better understand how SAP HANA functions in all the types of solutions you might require.
Real-World Scenario
You start a new project. The business users describe what they want and expect you to suggest an appropriate architecture for how to deploy SAP HANA. You have to decide between building something new in SAP HANA or migrating the current SAP system to use SAP HANA. You also have to decide if you should use SAP HANA in the cloud and, if so, which type of service you will need.
When you understand the internal architecture of SAP HANA, it can lead to unexpected benefits for the company. You can use the fact that SAP HANA uses compression in memory combined with an understanding of how SAP HANA uses disks and backups to provide a customer with an excellent business case for moving their business solution to SAP HANA; this can lead to dramatically lower operational costs and reduced risk.
Objectives of This Portion of the Test
The objective of this portion of the SAP HANA certification test is to evaluate your basic understanding of the various SAP HANA deployment scenarios and the corresponding system configurations. The certification exam expects SAP HANA modelers to have a good understanding of the following topics:
- How SAP HANA uses in-memory technology, including elements such as columns, tables, and compression
- The persistence layer in SAP HANA
- The various ways that SAP HANA can be deployed
- How SAP HANA can be deployed in the cloud
