What is CAP Operator, what are its main features, and how does it function?

In this episode, host Karsten Hohage speaks with Sathyajith Krishnan (SAP) and Pavan Nayak (SAP) about CAP Operator – which deploys and manages the lifecycle of multi-tenant SAP Cloud Application Programming Model applications and related components, based on SAP BTP golden path, within a Kubernetes cluster.

Sathyajith and Pavan explain the main features of CAP Operator and share an overview of the major automation steps handled by CAP Operator during the deployment of the application. The conversation also covers the operator’s evolution from an internal solution to an open-source resource, the foundational knowledge needed for users, and future enhancements planned for better integration and community engagement.

Sathyajith Krishnan is a Development Architect focused on building platform components which enable ease of consumption as well as access to the latest technologies for developers building business applications. For the past 16 years he has worked as part of product development teams as well as Customer specific implementation projects at SAP which has helped him gain unique perspectives on how to develop platform capabilities for both internal development teams as well as the external ecosystem.

What is Open Resource Discovery (ORD) and how can it be used and implemented inside SAP and beyond?

In this episode, host Karsten Hohage speaks with Simon Heimler (SAP) about Open Resource Discovery (ORD) – a protocol that allows applications and services to self-describe their exposed resources and capabilities. Simon explains in more detail what ORD is, how it’s used and where at SAP we already use ORD or plan to use it in the future. As the platform is an open standard by SAP geared towards the SAP ecosystem, how do we ensure a correct adoption of ORD at SAP? And how can it be helpful for individuals outside of SAP?
