Commercial Open Source: History, Licensing Wars, and the Cloud Conflict

Birth of Commercial Open Source

You cannot discuss commercial open source without mentioning Red Hat, the pioneer that went public in 2002 and became the world’s first $1 billion‑valued commercial open‑source company. Red Hat proved that a business could be built on a fundamentally religious‑like belief in open‑source software.

Initially focused on Linux, Red Hat later diversified into a trusted provider of many open‑source infrastructure products. Over the years, Linux and the open‑source stack have added immense value to the world, powering data centers, the New York Stock Exchange, space missions, and the birth of Android.

The rise of Linux and Red Hat created huge benefits for users and propelled the entire software industry, attracting new infrastructure companies that could freely use, modify, and combine open‑source code. This freedom is baked into the licenses and is part of the open‑source spirit.

IBM’s $36 billion acquisition of Red Hat provided market validation that open source has truly arrived.

Since Grafana Labs became a company in 2015, we have watched new commercial open‑source firms such as Elastic NV (creator of Elasticsearch) and MongoDB Inc. grow their communities and businesses, with dozens of other firms now generating over $100 million in annual revenue.

Software Becomes a Service

Red Hat originally sold Linux on CD‑ROMs through physical distributors. The shift from physical media to digital downloads and continuous updates gave rise to the subscription model, where customers pay for the software they consume rather than owning it.

This subscription mindset paved the way for Software‑as‑a‑Service (SaaS) and the broader cloud model, which initially relied on diverse data‑center ecosystems operated by telecoms and hosting providers.

Today, massive public‑cloud players such as Amazon Web Services (AWS), Microsoft Azure, and Google Cloud dominate, with AWS being the apex predator of the public‑cloud market.

While open source won the battle for infrastructure software, the public cloud—especially AWS—won the battle for where that software runs and how customers use it, setting the stage for conflict.

AWS: Friend or Foe?

AWS sells compute capacity and seeks to commodify complementary software, turning popular open‑source projects into managed services without paying the original developers.

Elasticsearch and MongoDB are examples of open‑source projects that AWS offers as services, effectively turning them into high‑margin products for a cloud vendor.

In October 2015, AWS launched Amazon Elasticsearch Service, a move that felt like a dark day for Elastic NV, which later had to acquire a startup to stay competitive.

Open Source Is Not a VC Business Model

Unlike Red Hat, many newer commercial open‑source companies adopt a hybrid “open core” model: they maintain an open‑source project while selling proprietary add‑ons (e.g., X‑Pack for Elasticsearch) to generate revenue.

These companies focus heavily on value creation and capture, often under pressure from venture‑capital expectations, and they build business moats around their commercial extensions.

Elastic NV, for instance, has expanded its Elastic Cloud offering, gone public in 2018, and is now valued at over $6 billion, but the licensing war with AWS continues.

The conflict between public‑cloud providers and commercial open‑source firms is far from over.
