Your SAP on Azure: SAP HANA Express on Azure Kubernetes Cluster (AKS)

Using a docker image to install SAP HANA express edition can shorten the deployment time and ensure the consistency between environments. The easy way to use it is to build a Kubernetes cluster using Microsoft Azure Container Service and deploy containers in the cloud.

A docker container is a package of libraries and system settings required to run an application. It allows to save the time needed to provide a working environment and you can focus on the target database configuration. It’s great especially in environments where you need to provide separated HANA instances for many developers.

S/4HANA – What to do about Planning and Consolidation – The Options

As organisations continue to convert their SAP ERP systems to S/4HANA, one area that pops up as a roadmap item is how to handle requirements for Planning and Financial Consolidation.

In some cases, this provides an opportunity to simplify the landscape and in others prompts a review of what organisations require from a planning solution and what they require from a financial consolidation tool. These discussions are made more confusing for SAP customers, because SAP provide a number of different solutions that cover the topics of planning and consolidation, and at first glance it can be difficult to understand which should be used.

Setting up communication channel between SAP Cloud Platform (Neo) & HANA XSA (On-Premise)

Overview


Recently, I came across a situation where I had to consume an OData service that’s deployed in HANA 2.0 on-premise following XSA paradigm in a SAPUI5 application running in SAP Cloud Platform – Neo environment. In this blog, I’d like to take through the concepts and the various configuration steps that are involved in setting up communication channel between an application deployed in SCP to and HANA XSA on-premise. I’ll also describe in detail the security configuration to allow a user logged in SCP HTML5 application to access a protected resource in HANA XSA, for example an OData service that requires specific scope to access.

Upgrading Web IDE in HANA Express

One of the housekeeping tasks I generally perform in the instances I use to develop actual applications is to upgrade the Web IDE. Not only because some minor bugs are swept away, but also because there’s always some additional functionality that makes development easier.

You would generally need access to the marketplace and a proper license for this. However, the engineering team has made this patch available for download in the download manager in revision 23. If the following rings a bell, you might want to give this a try:

How to free Hana System on Public Cloud from I/O performance issue?

How to free Hana System on Public Cloud from I/O performance issue?


Apart from memory, storage performance plays a major role in safeguarding HANA performance. Storage system used for SAP HANA in TDI environments must full fill a certain set of KPIs for minimum data throughput and maximum latency time for Hana data and log volume. Cloud vendor need to pass the KPI checked using HWCCT (Hardware Configuration Check Tool) for SAP to certify their cloud platform to run SAP HANA. The reason is to safeguard customer HANA system from any possible I/O performance that’ll lead to performance degradation up to system standstill and irresponsive.
