Why Does Salmon Swim Upstream

The value of commercially supported open source software.

Past: Jonathan Gershater

Why do salmon swim upstream? The fish swim upstream to spawn and their offspring return to the body of water to feed. Merely what if some of the fish, en road to the sea, took a tributary at a fork in the river? They might get lost, fail to achieve the sea and perhaps starve or frazzle themselves trying to find the original route. Developing software using open source principles follows a similar theory.

When software is developed using open up source philosophies, an upstream repository of the code is accessible to all members of the project. Project members contribute to the code, test it, write documentation and tin create a solution from that code to use or distribute under license. If an organisation follows the main stream or branch of the upstream code their solution will receive all the changes and updates created in the upstream repository. Those changes simply "flow down" to the member'southward solution.

However, if a member organisation forks the code — if they create a solution that strays from the chief stream — their solution no longer receives updates, fixes and changes from the upstream repository. This organization is now solely responsible for maintaining their solution without the benefit of the upstream customs, much similar the salmon that took a tributary and then take to fend for themselves rather than remain in the main stream and receive the benefit and guidance of the other salmon making their fashion to the bounding main.

Cerise Hat has a 100% upstream commencement philosophy. Red Hat software is not forked from the upstream.

Cerise Chapeau OpenShift is non a fork of upstream Kubernetes, rather it is a merger of key open source projects required to deliver an Enterprise ready solution.

Below is an illustration of contributions to some of the key open source projects, comprising OpenShift, that Red Hat contributes to:

Linux Kernel

Cherry-red Chapeau is the 2d largest contributor to the Linux kernel. This means Crimson Hat engineers and support staff are well versed and able to resolve customer bug involving the Linux kernel. Every application container includes office of the Linux distribution and relies on the Linux kernel, which is the centre of the Linux Operating System.

Contributions to Kubernetes

Kubernetes, every bit divers by the project, is an open-source system for automating deployment, scaling, and management of containerized applications. Red Hat is ranked about the top for Kubernetes contributions

Contributions to Deject Native Computing Foundation

The Cloud Native Calculating Foundation, as divers by the foundation, builds sustainable ecosystems and fosters a community around a constellation of high-quality projects that orchestrate containers as function of a microservices architecture. CNCF serves equally the vendor-neutral home for many of the fastest-growing projects on GitHub, including Kubernetes, Prometheus and Envoy, fostering collaboration between the manufacture's peak developers, cease users, and vendors. Cerise Hat ranks near the top for contributions.

Conclusion

The loftier level of contributions by Red Hat to Kubernetes and associated projects demonstrates that Crimson Chapeau is:

Committed to the projects.
Investing time and money.
Engineering Ruby-red Lid solutions to be 100% upstream compliant.

Different salmon that might take a fork in the river and jeopardize their journey to the ocean to feed and grow, Red Chapeau never forks upstream software. Thus users of Cherry Hat software can exist confident that they volition become software that has been debated and vetted in the public forum, letting it mature through a cycle long before it reaches their networks and information centers.
