Apache Pinot
Real-time distributed OLAP datastore for user-facing analytics at high concurrency and low latency. Apache-governed. A heavy multi-node cluster to run; managed ops and anomaly detection are the commercial StarTree.
Apache Druid
Real-time analytics database for sub-second queries on streaming and batch data, Apache-governed. A heavy distributed cluster to operate; managed ops and the Pivot BI console are the commercial Imply.
StarRocks
Real-time MPP OLAP database that queries open lakehouse tables directly. Apache-licensed, Linux Foundation-governed. A distributed cluster to run; masking and managed ops are the commercial cloud.
Apache Doris
Real-time MPP data warehouse, MySQL-compatible and Apache-governed, built to leave cloud warehouses like Snowflake. A distributed cluster to run; SSO and managed ops sit with the commercial VeloDB.
Zot
OCI-native container registry in a single static binary with RBAC, scanning and replication built in, no external database. Apache-licensed, no paid tier. A younger CNCF Sandbox project than Harbor.
Quay
Red Hat's Apache-licensed container registry with integrated Clair scanning, geo-replication and RBAC in the free core. Multi-service stack; roadmap steered by Red Hat and tied to OpenShift.
Distribution
Minimal Apache-licensed OCI registry, formerly Docker Registry: stores and serves container images with pluggable S3 or filesystem storage. No built-in auth, RBAC or UI; you wrap it or run Harbor on top.
Harbor
CNCF-graduated container registry that stores, scans and signs OCI images. RBAC, replication and audit logging ship in the free Apache core with no paid tier. Runs as a multi-service stack, so weigh the operational weight.
Resources
Essential frameworks for the modern decision-maker. Deep dives on licensing, deployment standards, and security to secure your digital stack.

Open Source is free until it isn't.
Open source is not the opposite of paying for software. Four business models hide behind one label: foundation-run, open core, source-available, and support-funded. Buy a stack and you inherit all of them. What breaks on day two, and the four questions to ask before you sign.

Europe had a Sovereign Cloud. Customers left it.
Microsoft built a sovereign German cloud and locked itself out of it. Customers left anyway. The real premium was never just the money, it was capability, and Europe is now writing its cloud sovereignty law around a gap it never closed.

You can run it. You cannot use it.
A frontier open model now runs on a desktop. It writes five words a minute. I tested a smaller one on my own machine and it ran slower than someone reading aloud. Running these models yourself is real. It is a fire escape, not a workplace, and there is no third state between working and gone.
