1. Cloudflare: The Network Is The Computer
Sun’s old motto, “The network is the computer,” was a visionary statement that arrived decades early. They dreamed of a world where computation and data were distributed, accessible from anywhere. Today, Cloudflare is arguably building the truest version
of that vision. Starting as a service to protect websites from attacks, it has relentlessly expanded into a global supercomputer. It offers serverless computing (Workers), data storage (R2), and a vast array of network services that allow developers to build applications directly on the edge of the internet, bypassing traditional cloud providers. Like Sun, Cloudflare is driven by a deep-seated engineering culture obsessed with performance and infrastructure. The parallel is in the core philosophy: stop thinking about individual servers and start thinking about the power of the distributed network itself. The question for Cloudflare is whether it can avoid Sun’s fate of being the visionary that sets the table for others to feast.
2. HashiCorp: The Open Source Conundrum
Sun Microsystems had a famously complicated relationship with open source. They created Java, one of the most important programming languages ever, but fought fiercely to control its direction. They open-sourced their Solaris operating system and ZFS file system, but only after years of debate and often too late to win the market. This tension is alive and well at HashiCorp. For years, the company was a champion of open-source tools like Terraform and Vault, which became industry standards for managing cloud infrastructure. But in 2023, HashiCorp shifted its core products from a permissive open-source license to a more restrictive Business Source License (BSL). The move, intended to prevent competitors from profiting off their work, was a direct echo of Sun’s struggle to balance community goodwill with commercial necessity. It sparked a community backlash and a project fork—the same playbook that unfolded around Sun’s open-source projects two decades ago.
3. Cerebras Systems: The Big Iron Bet
In a world increasingly dominated by commodity Intel x86 processors, Sun insisted on building its own custom SPARC chips and the high-end servers to run them. It was a bet on integrated, high-performance hardware—a bet they ultimately lost to the cheaper, “good enough” solutions. Today, Cerebras Systems is making a similarly audacious hardware bet in the age of AI. While Nvidia’s GPUs dominate the AI training market, Cerebras is building something far more radical: wafer-scale engines. These are single, dinner-plate-sized chips containing trillions of transistors, designed to train AI models faster than any competitor. Like Sun’s high-end servers, Cerebras’s machines are a feat of engineering, an expensive and highly specialized alternative to the commodity tide. It’s a classic “big iron” play, betting that for the most demanding problems, a bespoke, integrated system will always beat a collection of commodity parts. The risk, just as it was for Sun, is being a brilliant solution for a niche that isn't big enough to sustain the business.
4. Epic Games: The Platform-War Pugilist
One of the defining sagas of Sun’s history was its bitter war with Microsoft over Java. Sun saw Java as a “write once, run anywhere” platform that would break Microsoft’s Windows monopoly; Microsoft saw it as an existential threat and tried to “embrace, extend, and extinguish” it. This clash of titans over platform control is being replayed today in Epic Games’ fight against Apple. Epic, powered by its Unreal Engine and the massive success of Fortnite, has challenged Apple’s 30% App Store fee and its tight control over the iOS ecosystem. Just like Sun vs. Microsoft, this isn’t just a business dispute; it’s a philosophical and legal war over what it means to own a platform, the rights of developers, and the future of distribution. Epic CEO Tim Sweeney’s rhetoric about open platforms mirrors the language Sun’s executives used against Microsoft, making this a fascinating modern parallel of a classic tech showdown.
5. Palantir: The Controversial Visionary
Sun was staffed by brilliant engineers who believed their technology could solve the world’s most complex problems, sometimes displaying a hubris that alienated partners and customers. They sold powerful systems to governments and massive corporations, operating at the highest levels of the tech world. Palantir embodies this same spirit of elite, controversial problem-solving. The data analytics company, known for its secretive work with defense and intelligence agencies, builds powerful software to integrate and analyze vast, disparate datasets. Like Sun, Palantir projects an aura of intellectual superiority and has a reputation for tackling problems others can't. And like Sun, its close ties to government and its belief in a specific technological worldview (in this case, centered on data integration) make it a lightning rod for controversy. Palantir is betting its vision of how organizations should use data is the future, much as Sun bet its vision of networked computing was the future.
