Symfony to the Cloud: Twelve Factors, Thirteen Services

Sun, 17 May 2026 15:00:00 +0000

An eight-part series following the migration of a Symfony microservices platform from Docker Compose to Kubernetes, through the lens of the twelve-factor methodology. Each article isolates one category of problem — storage, secrets, logs, service dependencies, CI environment parity, distributed cache, readiness probes, schema governance — and reads it against the twelve-factor principles that apply.

Symfony Releases

Mon, 12 Jan 2026 00:00:00 +0000

Symfony releases land on a predictable schedule, but the signal-to-noise ratio in release notes is low. This series distills each version to what actually changed the way you write Symfony applications.

PHP Releases

Sun, 04 Jan 2026 00:00:00 +0000

Each major and minor PHP release brings changes worth understanding beyond the changelog. This series covers what actually matters in each version: the features that stuck, the ones that didn’t, and why they were added in the first place.

API Platform Releases

Thu, 18 Sep 2025 00:00:00 +0000

API Platform 3.0 was not a feature release — it was a rewrite. Each version since has refined the architecture introduced then: state providers and processors, PHP 8 attributes, OpenAPI 3.x, and a cleaner separation between the HTTP layer and the domain. This series covers what actually changed in each release and why it matters for how you build APIs.
