Based on the [press release](https://www.datadoghq.com/blog/datadog-acquires-quickwit/) it looks like they're hinting towards offering a 'self-hosted' model for customers that can't use pure SaaS solutions due to regulations:

> Organizations in financial services, insurance, healthcare, and other regulated industries must meet stringent data residency, privacy, and regulatory requirements while maintaining full visibility into their systems. This becomes challenging when logs need to remain at rest in customers’ environments or specific regions, hindering teams’ ability to attain seamless observability and insight. To help our customers meet these requirements without sacrificing visibility or introducing multiple logging tools, we are pleased to announce that Quickwit—a popular open source distributed search engine—is joining Datadog.
