The documentation you selected refers to Dynatrace functionality delivered only as a SaaS (software as a service). To learn more about Dynatrace, see What is Dynatrace.
Some innovations leverage the power of Grail, which is available only in Dynatrace deployed as SaaS.
Grail is the Dynatrace data lakehouse designed explicitly for observability data. It's a unified storage solution for logs, metrics, traces, events, and more. All data stored in Grail is interconnected within a real-time model that reflects the topology and dependencies within a monitored environment.
At a massive scale, the underlying infrastructure attributes need to be consistently implemented, controlled, and balanced, which is not practical in physical data centers.
Grail is generally available to all Dynatrace SaaS customers deployed on AWS or Azure.
Fantastic.
To take full advantage of the cloud with Dynatrace SaaS, start with Upgrade from Managed to SaaS deployment for an overview of the migration process.
Don't worry.
Dynatrace Managed continues to be a market-leading option for customers with mandatory on-premises requirements.
Dynatrace is committed to supporting Managed customers and will continue to provide monthly product updates with many innovations that don't require Grail capabilities. The Managed Dynatrace roadmap doesn't include planned Grail support, as Grail was architected explicitly for SaaS and massively parallel processing.
An important action you can take now is to precisely define your organization's blockers to upgrading your Dynatrace Managed to Dynatrace SaaS.
If you aren't sure whether you're ready to upgrade to SaaS, the Dynatrace Managed to SaaS Readiness Assessment will help you decide.
