Sōzu 2.0 — turning a reverse proxy into a programmable edge
Sōzu is the reverse proxy that sits in front of every application running on Clever Cloud. After eighteen months of work — first the HTTP/2 multiplexer, built on our existing kawa pivot, then almost every other layer of the proxy, and finally a long run in production on the cleverapps.io load balancers — Sōzu 2.0 is out.
K3s vs K8s: What Are the Differences and Which One Should You Choose in 2026?
Kubernetes has become the standard for container orchestration. But depending on your infrastructure constraints (limited resources, edge computing, IoT, or large-scale enterprise clusters), the distribution you choose can radically change the operational experience. K3s and K8s (upstream Kubernetes) address different needs, even though both share the same CNCF-certified foundation.
How Clever Cloud responds to kernel vulnerabilities
How Clever Cloud reacted to recent kernel vulnerabilities, reduced exposure, and improved its kernel deployment process.
K8S: What Is Kubernetes, How It Works, and Why It Became the Standard
K8S, short for Kubernetes, is an open source container orchestration system originally developed by Google and donated to the Cloud Native Computing Foundation (CNCF) in 2015. It automates the deployment, scaling, resilience, and networking of containerized applications across clusters of servers. In just over a decade, K8S has become the technical foundation on which a majority of modern cloud applications run.
Clever Cloud Takes Control of Its IP Prefix Announcements
Since January 22, 2025, Clever Cloud has been announcing its own IP prefixes on the Internet in our Paris region. We now manage this critical part of our network infrastructure internally, rather than delegating it to a third party.
CKE in public beta: managed, sovereign, and properly integrated Kubernetes
Clever Cloud was founded in 2010. At that point, Docker did not exist, and Kubernetes even less. The problem, however, was already there: running our first customers' applications reliably, in isolation, and predictably.
Cloud modernisation: how to align governance and operations without adding complexity
European organisations are managing increasingly heterogeneous environments: legacy applications, cloud-native services, multi-cloud setups and regulatory constraints are accumulating within information systems rarely designed to handle such diversity.
Clever Cloud launches Clever Kubernetes Engine (CKE) in public beta on April 27, 2026
Previewed at Devoxx starting April 22, CKE is the culmination of two years of R&D built around a complete reimplementation of Kubernetes.
OpenTofu: the open-source Terraform fork — natively supported on Clever Cloud
In August 2023, HashiCorp changed Terraform's license. A few weeks later, OpenTofu
was born under the Linux Foundation. Here's what it means — and how to use it
with the Clever Cloud provider.
When choose a PaaS for a public sector project
Public services are engaged in an ongoing digital transformation, driven by increasing user expectations, service continuity requirements, and growing security needs.
How We Deployed a Vinext Application in Minutes on Clever Cloud with AI
Cloudflare has just announced Vinext, a drop-in replacement for Next.js built on Vite. The project is vibecoded, experimental, but the promise is compelling: builds up to 4x faster, bundles 57% lighter, and 94% coverage of the Next.js API. We wanted to see how easy it would be to deploy it on Clever Cloud.
New IAM feature: what our Managed Keycloak offers today
Since its launch, Keycloak as a Service has evolved significantly to meet the concrete needs of businesses and the requirements of operating IAM at scale.
Elasticsearch Observability: logs, metrics, and traces explained
Modern architectures generate ever-growing volumes of data. Microservices, APIs, cloud workloads, and serverless environments multiply potential failure points. In this context, understanding what is really happening in production has become a central challenge.
ELK Stack: what it is used for and how to use it for observability
Understanding what is really happening inside a modern application has become increasingly complex. Microservices, cloud environments, and the growing number of physical or virtual servers all contribute to an explosion of technical signals. This distribution makes so-called “traditional” log analysis—based on directly connecting to a single machine—hard to sustain at scale.
Identity Access Management: pillar of security and compliance
Identity Access Management (IAM) is now one of the foundations of information system security and governance.…
Deployment variables got more consistent
When deploying your applications to Clever Cloud, you can configure the build and start of your application or secondary services using Environment Variables.
8 open source IAM solutions to structure access management
Identity and Access Management (IAM) defines how an organisation controls access to applications, APIs and data.
Manage your WordPress identities with Keycloak
Managing logins to your website can be a complex task. Fortunately, tools like Keycloak, an open-source Identity and Access Management (IAM) solution, can make it much easier to handle authentication and authorization for your application.
Building Smarter MCP Servers — From Theory to Practice
A few months ago, I published an article introducing MCP servers. Since then, I’ve…
Why we (finally) built our own managed Kubernetes
At Clever Cloud, we held off for a long time before offering a managed Kubernetes service. Not out of technological reluctance, Kubernetes is a great tool… but it was never designed to make developers’ lives easier.
