Sponsored: Three architectures to make your data stack more efficient in 2023
RudderStack details three practical ways to make your data stack more cost-effective and your data team more efficient.
Eliminating integration engineering work.
Using your data warehouse instead of an expensive CDP.
Using APIs, instead of expensive 3rd party services, for data enrichment.
It includes details on an interesting use of a data transformation (written in Python), Webhook, and an internal signup API to streamline app signups from their marketing site. A key highlight of the blog
Their data team leveraged a cost-effective geolocation API to solve the problem. In a RudderStack Transformation, they passed the user’s IP address to the service and appended the returned region to the payload, which was passed into a custom field in the marketing platform.The marketing team was then able to automatically segment users into regional lists and trigger location-based offers in real-time.
