Does CAP replace HANA XSA ?

[dvankempen]

Hi,

Cloud application programming model (CAP) allows you (among other things) to create hana db artifacts using CDS.

So, Does this replace HANA XS Advanced for developing hana native applications in the cloud ?

It seems that CAP is the model that SAP is fostering also for this hana developments in the cloud, So will hana xs advance be deprecated ? I guess HANA XSA is still an option for on-pre.

Can anyone advise, please ? Is there some kind of roadmap depicting the strategy for these developments.

Thank you !

Good question, Andrew

CAP started off as the Application Programming Model for SAP Cloud Platform-Cloud Foundry applications. The focus is on CF apps but is not specific to SAP HANA. Any development tool can be used to work with the model but SAP Business Application Studio provides built-in support. CAP was introduced in 2018, The GA release of BAS was in 2020. After CDS for HANA and CDS for ABAP, you could see this as CDS for SCP CF.

The focus of XS Advanced programming model is SAP HANA platform either with a local runtime (XSA) or cloud-based (SAP Cloud Platform, Cloud Foundry). Any tool can be used to work with the model but SAP Web IDE provides built-in support. XSA and Web IDE were introduced in 2015/16. Implements CDS for HANA.

The MTA concept (2017) is supported by both tools and both programming models.

Unlike previous SAP HANA DBaaS editions, SAP HANA Cloud does not include XS Classic nor the XSA runtime environment. From an architecture point of view this makes sense as the Cloud Platform already provides these runtime environments.

If your objective is to build cloud applications, using CAP is recommended. The model is well documented and there is an abundance of training material.

When you want to develop native applications for the SAP HANA platform (potentially but not necessarily to be deployed on the Cloud Foundry runtime of the SAP Cloud Platform as well), you could continue to work with the older XSA model.
