SAP is used as key business application in most of the organization globally. Enterprises are leveraging in-memory computing of SAP HANA for faster decision making for their business. The partnership between AWS and SAP goes back more than a decade. Not only is SAP one of AWS's largest customers, but more than 5,000 customers run SAP on AWS. More than half of those businesses are using SAP HANA-based solutions. SAP is encouraging its customers to adopt SAP HANA on a cloud-native architecture. Also, AWS has worked closely with SAP to test and certify a subset of Amazon EC2 instance types for SAP HANA solutions.
I have a lot of customer conversations about SAP HANA hardware. It’s no wonder, given that there are more than 1000 certified appliances on the Certified SAP HANA Hardware Directory at the time of writing. But for better understanding - let's discuss about the basics first.
SAPS
SAP Application Performance Standard (SAPS) is a hardware-independent unit of measurement that describes the performance of a system configuration in the SAP environment.
In technical terms, this throughput is achieved by processing 6,000 dialog steps (screen changes), 2,000 postings per hour in the SD Benchmark, or 2,400 SAP transactions.In the SD benchmark, fully business processed means the full business process of an order line item: creating the order, creating a delivery note for the order, displaying the order, changing the delivery, posting a goods issue, listing orders, and creating an invoice.
OLTP and OLAP
OLTP and OLAP are general terms used to roughly divide database workloads into two main classes.
A transactional or OLTP (online transaction processing) workload is a workload typically identified by a database receiving both requests for data and multiple changes to this data from a number of users over time where these modifications are called transactions.
OLTP is mainly used for Transactional Applications e.g. SAP ERP.
OLTP Characteristics:
- Many transactions
- Latency sensitive
- Small payloads
- Heavy write or balanced read/write workloads.
OLAP (online analytical processing) is a computing method that enables users to easily and selectively extract and query data in order to analyze it from different points of view.
OLAP is used mainly for Data Mining, Modeling, Analytics, Reporting, etc. e.g. SAP BW.
OLAP Characteristics:
- Relatively few transactions
- Throughput sensitive
- Large payloads
- Heavy read workloads including full table scans, if required.

Standalone, Scale-up and Scale-out
SAP HANA Standalone
SAP HANA can be installed on single independent computer as one system.
There are two ways to scale SAP HANA into large systems – up, or out.
For a standalone system, only scaling up is possible by increasing H/W capacity like memory, storage, etc.
SAP HANA Scale-out
Scale-out means combining multiple independent computers into one system. All the computers should be of same size & configuration. The main reason for distributing a system across multiple hosts (i.e, scaling out) is to overcome the hardware limitations of a single physical server. This allows an SAP HANA system to distribute the load between multiple servers.
SAP HANA Certified Instances on AWS
Here are the list of the Amazon EC2 instance types(current generation instance types only) that are certified and supported for SAP HANA as of August’2021. Instance types comprise varying combinations of CPU, memory, storage, and networking capacity and give you the flexibility to choose the appropriate mix of resources for your applications. Each instance type includes one or more instance sizes, allowing you to scale your resources to the requirements of your target workload.
*OLTP Scale-Out supported **OLAP Scale-Out supported
