Oracle has announced it has joined the Cloud Native Computing Foundation (CNCF) at the platinum level, boosting its push for Kubernetes with new open source product releases.

The foundation, whose role is to help sustain containers and microservices architectures, said Oracle’s ‘key role will help define the future of enterprise cloud.’

“CNCF technologies such as Kubernetes, Prometheus, gRPC and OpenTracing are critical parts of both our own and our customers’ development toolchains,” said Mark Cavage, vice president of software development at Oracle. “Together with the CNCF, Oracle is cultivating an open container ecosystem built for cloud interoperability, enterprise workloads and performance.”

Oracle becomes the third such vendor to sign up to the CNCF in a matter of weeks, after Amazon Web Services (AWS) confirmed its participation earlier this month and Microsoft did so in July. The cast list of the CNCF now reads like a who’s who of cloud computing, with Oracle the last holdout among the first and second tier players.

Alongside this, Oracle is releasing Kubernetes on Oracle Linux, as well as open sourcing a Kubernetes installer for its cloud infrastructure. “Developers gain unparalleled simplicity for running their cloud native workloads on Oracle,” as the company put it.

This is one of various initiatives Oracle has recently been putting into place regarding open source. The company announced in June it was making investments into Kubernetes, with a blog post from the developer team saying at the time: “Oracle is investing in Kubernetes first and foremost as a way to deploy and operate our new cloud services. We think our understanding of operating Kubernetes will translate into value for the community as we turn our real-world experience into action.” In the same month, Oracle also announced three new open source container utilities.

The company’s most recent financial results, in June, saw total cloud revenues hit $1.36 billion (£1.06bn), or 13% of overall revenue, with Larry Ellison predicting its platform as a service (PaaS) and infrastructure as a service (IaaS) businesses will outperform the software arm in due course.

With Q118 earnings set to be announced later today, Wallace Witkowski, writing for MarketWatch, said the company is “expected to mark a major milestone in its transition from traditional software sales to the cloud.”
