[PHPForumParis2022] Internet and Geopolitics – Stéphane Bortzmeyer
Stéphane Bortzmeyer, a seasoned expert in Internet infrastructure, delivered a thought-provoking presentation at PHP Forum Paris 2022, exploring the intricate relationship between the Internet and geopolitics. Dedicated to Mahsa Amini, whose tragic death sparked a revolt in Iran, Stéphane’s talk illuminated how global politics shape the Internet’s architecture and accessibility. With a focus on real-world examples, he challenged developers to consider the geopolitical implications of their work, particularly in the context of PHP-driven applications that rely on global connectivity.
The Myth of the Cloud
Stéphane began by debunking the term “cloud,” criticizing it as a marketing ploy that obscures the Internet’s physical and political realities. Far from being a borderless entity, the Internet is deeply tied to national jurisdictions, data centers, and political decisions. He highlighted how regimes, such as Iran’s, manipulate Internet access to suppress dissent, using censorship and throttling to control information flow. For PHP developers, this underscores the importance of designing applications that account for such restrictions, ensuring accessibility and resilience in diverse geopolitical contexts.
Global Connectivity Challenges
Delving into connectivity, Stéphane explained how historical and economic factors create disparities in Internet access. He cited Colombia, where local content is often hosted abroad due to limited domestic infrastructure, creating a self-reinforcing cycle of dependency on foreign connections. This phenomenon, driven by business interests rather than technical necessity, affects latency and accessibility for PHP applications. Stéphane urged developers to advocate for local interconnection and consider hosting strategies that prioritize user experience in underserved regions.
The Role of Regulation and Advocacy
Addressing regulatory responses, Stéphane contrasted Bolivia’s legal mandates for local interconnection with Europe’s reliance on user and government pressure. He emphasized that developers can influence these dynamics by supporting open Internet standards and advocating for equitable access. For PHP developers, this means building applications that are adaptable to varying network conditions and contributing to discussions on infrastructure policies. Stéphane’s insights highlighted the developer’s role in fostering a more inclusive and resilient Internet.
Empowering Developers to Act
Concluding, Stéphane called on developers to engage with the geopolitical aspects of their work, from choosing hosting providers to supporting open standards. By understanding the Internet’s physical and political constraints, PHP developers can create applications that better serve global audiences. His dedication to Mahsa Amini served as a poignant reminder of the stakes involved, inspiring attendees to approach their craft with a broader perspective on its societal impact.

[DevoxxFR2015] Evolving Infrastructure Without Downtime: CloudBees’ Journey
Nicolas De Loof, an Apache Maven committer and founder of BreizhJUG, delivered an engaging session at Devoxx France 2015, stepping in for his colleague Michael Neale. Representing CloudBees, Nicolas shared the company’s evolution from a fragmented startup to a robust, globally available system, focusing on seamless infrastructure migrations without interrupting service. His narrative, infused with humor and practical insights, highlighted transitions to multi-tenant architectures and Docker-based deployments.
From Startup Chaos to Structured Systems
Nicolas began by outlining CloudBees’ early days, marked by ad-hoc technical decisions that later demanded refinement. Initial choices, such as a custom LXC-based solution, became obsolete as the company scaled. He described the challenge of maintaining zero downtime across a global user base, necessitating careful planning to evolve infrastructure while keeping services operational.
This journey, Nicolas emphasized, required strategic foresight.
Migrating to Multi-Tenant Architecture
The shift to a multi-tenant build-on-demand system was a cornerstone of CloudBees’ transformation. Nicolas detailed how this migration, spanning months, consolidated resources to improve efficiency without impacting users. By gradually phasing in the new architecture, the team ensured continuity, addressing regrets from earlier single-tenant designs that strained scalability.
This transition, he noted, enhanced resource utilization.
Adopting Docker for Containerization
Replacing LXC with Docker marked another pivotal change. Nicolas explained how Docker’s containerization simplified deployment and management, offering greater flexibility than the bespoke LXC setup. The migration, executed incrementally, maintained service uptime, with Docker’s lightweight containers streamlining operations across CloudBees’ infrastructure.
This adoption, Nicolas highlighted, modernized their platform.
Operational Best Practices
Drawing from CloudBees’ experience, Nicolas stressed the importance of health checks, monitoring, and termination strategies to prevent service disruptions. His lighthearted “Salut les Geeks” conclusion, inspired by a YouTube series, underscored practical advice: robust monitoring prevents “blonde” moments where systems fail silently. He urged teams to integrate these practices early to avoid production chaos.
These strategies, he concluded, ensure resilient operations.
