Compute Distance using a Calculation View – XS Advanced Model

We’re going to learn how to create a Graphical Calculation View to calculate the distance between two locations or coordinates represented by a longitude and a latitude. We assume that some of these locations or coordinates are already known and the other is an input from the user.

This is achieved by using the HANA spatial capabilities. HANA support three spatial reference systems (SRS) by default. For this blog we will use the WGS84 – SRID 4326 SRS because HANA supports it and the coordinates used are based off Google Maps.

Installing SAP HANA database using self service on SAP Cloud Platform

A new capability was released on SAP Cloud Platform to allow customers to perform installation of SAP HANA/ASE database instance in a self-service manner. Prior to this, there was a manual process in place. If a customer has an existing SAP Cloud Platform subscription with several subaccounts and decides to subscribe to a HANA DB, they would have to raise a support ticket requesting the assignment of a HANA DB to a particular subaccount. Behind the scene, the SAP Cloud Platform DevOps team would install the HANA DB and assign it to the requested subaccount.

Enterprise applications with optimized costs – SAP HANA-based systems on Hetzner Online

In this article I would like to share my experience  of building our company SAP infrastructure and hardware costs optimization that we  have managed to achieve. Currently we have over 20 internal sap systems in our internal  landscape, including about 15 HANA-based installations. We use a combined approach with Hetzner Online and Amazon web services, and our average monthly expenses  for hardware rental are about EUR 1,000.  In fact, this is not a productive landscape, so most of those tricks  will not work once you have mission-critical systems. However, in many production  scenarios serious costs saving can be achieved, and this is what I am going to describe below.
