Hello, I'm interest in specific aspects of internal developer platform|portal and related practices and I'm mostly interested in the data. I know couple of folks ran some survey to gather specific information or insights related to the following topics, I would greatly appreciate your help finding these informations (and not ask the same questions again): 1. The decision-making process between 'Buy' and 'Build' for an Internal Developer Platform. 2. Factors influencing the choice between 'Buy' and 'Build' for an Internal Developer Portal. 3. Total Cost of Ownership (TCO) considerations in the 'Buy' vs. 'Build' decision. 4. Primary reasons for choosing to 'Build' rather than 'Buy.' 5. Budget allocation or estimated spending on Internal Developer Platforms and Portals. Metrics, survey, blogs, etc, will help us drive some difficult conversations with stakeholders. Thank you!
