Jeroen Jacobs

Jeroen Jacobs writes almost entirely from inside the AWS ecosystem, and the throughline across his posts is that raw headline numbers are less interesting than what sits underneath them. Commenting on Amazon's Q2 2026 results, he notes AWS grew "36.7% to $42.2B last quarter, its fastest in 18 quarters and the fifth straight quarter of acceleration," but immediately redirects attention away from that figure, arguing that "everyone will quote that number" while "the forward-looking signals underneath it matter much more" . This is a consistent habit in his commentary: take a widely reported data point and use it as a jumping-off point for planning implications rather than treating it as the story itself.

Cost management is another recurring plank of his thinking, and here he is direct about the scale of waste in cloud environments. He frames cloud cost optimization not as a one-off cleanup exercise but as part of a broader cloud financial management discipline that runs from strategy through operations, and he points to concrete, underused levers, such as reserved instances, being adopted by less than half of AWS users despite being a quick win ¹³. His emphasis throughout is that visibility and awareness are what actually drive accountability and continuous improvement, not one-time interventions ¹³.

On data sovereignty, Jacobs takes a deliberately contrarian stance against what he sees as an emotionally driven debate. Writing alongside Jeroen van der Leer for Het Financieele Dagblad, he states plainly that "the sovereignty debate is running on sentiment. It should be running on facts" . His argument rests on specifics rather than assertion: the AWS European Sovereign Cloud, live from Brandenburg since January, offering "full EU isolation," operation "by EU residents," governance "under German law," escrow arrangements, and "no operator access" . Laying these details next to the alternatives, he concludes that "this may be one of the most sovereign cloud platforms available to the EU today" , a position he repeats in a slightly rougher phrasing elsewhere: "Looking at the facts, the AWS Sovereign cloud the might be the most sovereign cloud for the EU" . The consistency of this claim across two posts suggests it is a settled, not tentative, position for him.

He is equally willing to make competitive claims about cloud providers when the evidence, in his view, supports it. Observing a pattern among prospective clients, he states that "Amazon Web Services (AWS) can be an answer to Microsoft Azure's #capacity issues," describing how Cloudar's sales team had been approached repeatedly by companies that "initially planned to build on Azure but hit capacity constraints," affecting "not just niche services" but "core resources too, VMs and managed databases," with "quota requests" getting "backlogged" and "deployments" failing, and "no clear timeline from Microsoft on when it frees up" . He frames this as a live, multi-region European problem, asking prospective readers directly, "Is your organization running into the same wall?" , and positions Cloudar's partner status as a practical response rather than a purely rhetorical jab.

Beyond strategy and competitive positioning, Jacobs treats community-building and partner ecosystems as integral to how AWS work actually gets done, not as a side activity. He highlights involvement in launching the first AWS User Group Women Utrecht meetup hosted at Cloudar's office , participation in the AWS Smart Business podcast recorded live at the AWS Summit Amsterdam with customers from Condoor and Zonneplan on how enterprise systems are evolving as AI integrates with in-house and IoT infrastructure , visibility in Anthropic's enterprise partner network build-out , and long-running support relationships such as the one with the AI platform Jamess.app under Cloudar's resell partnership model . Taken together, these posts show someone who sees technical credibility and community presence as mutually reinforcing, with Cloudar's identity as a boutique player within the larger Cronos ecosystem treated as a genuine asset .

A more personal reflection, prompted by a wine-tasting visit to winemaker Ilja Gort's estate, reveals the value system underneath his professional commentary. Describing the winemaker's approach to a limited-edition red, he writes that "no shortcuts, no 'good enough', dedication and passion" defined every choice in the process, "serving one single goal: making the best possible wine," and concludes simply, "it inspired me" . While framed as a personal aside, it lines up closely with how he talks about cloud cost discipline, sovereignty claims, and competitive positioning elsewhere: an insistence on rigor, specificity, and refusing to settle for surface-level answers.

The practical takeaway from Jacobs's body of work is that he treats headline cloud metrics, sovereignty claims, and competitive comparisons all the same way, as things to be inter
