- HANA has the most expensive hardware in its category. This brings up important questions regarding the management of development and test environments.
Introduction to HANA Development and Test Environments
Development and testing environments are always critical, but with HANA the issue is of particular importance. The following quotation explains the alterations within HANA.
“Taking into account, that SAP HANA is a central infrastructure component, which faced dozens of Support Packages, Patches & Builds within the last two years, and is expected to receive more updates with the same frequency on a mid-term perspective, there is a strong need to ensure testing of SAP HANA after each change.”
The Complications of So Many Clients and Servers
HANA uses a combination of clients and servers that must work in unison for HANA to work. This brings up complications, i.e., a higher testing overhead when testing any new change to any one component. SAP has a process for processing test cases to account for these servers.
“A key challenge with SAP HANA is the fact, which the SAP HANA Server, user clients and application servers are a complex construct of different engines that work in concert. Therefore, SAP HANA Server, corresponding user clients and applications servers need to be tested after each technical upgrade of any of those entities. To do so in an efficient manner, we propose the steps outlined in the subsequent chapters.”
HANA development environments can be acquired through AWS at reasonable rates. This has the extra advantage that because of AWS’s elastic offering, volume testing can be performed on AWS’s hardware without having to purchase the hardware. Moreover, the HANA AWS instance can be downscaled as soon as the testing is complete. The HANA One offering allows the HANA licenses to be used on demand. This is a significant value-add as sizing HANA has proven to be extremely tricky.
