01 · WHY SYMFONY

Symfony 7 for systems that live a decade in production.

Decoupled components, clear contracts and hexagonal architecture by default. Symfony 7 sustains B2B platforms, custom ERPs and APIs with rich domain through years of evolution.

01

Decoupled components and bundles.

Symfony is composed piece by piece. HttpFoundation, Routing, Security, Serializer and Validator assembled per case. Autowiring, autoconfiguration and Flex recipes integrate libraries without manual configuration.

02

Doctrine ORM for complex domains.

Rich entities, value objects, inheritance and aggregates on PostgreSQL or MySQL. Versioned migrations, tuned DQL queries and fine-grained mapping for systems with dense business rules.

03

Headless, schema-first API Platform.

REST, GraphQL and JSON-LD from the same entity. OpenAPI generated, Mercure for real-time and built-in JWT. Backends ready for Next.js, Nuxt or mobile frontends.

04

Messenger for CQRS and event bus.

Commands, events and queries with Symfony Messenger on RabbitMQ, Redis or Amazon SQS. Idempotent workers, retries with backoff and dead-letter queues for critical asynchronous integrations.

05

Sylius and product ecosystem.

Sylius as a headless e-commerce base on top of Symfony, EasyAdmin for back-office and proven bundles for multi-tenant, multi-channel and workflow. We move faster without locking the roadmap.

06

LTS, security and code quality.

Official LTS releases, regular security patches and SymfonyInsight as the quality reference. PHPStan at max level, PHPUnit with domain coverage and Rector for safe refactors.

02 · TECHNICAL DECISION

Four scenarios where Symfony fits like nothing else.

Every Symfony project starts from the case, the team and the product horizon. We model the decision and write it down in an ADR before the first line of code.

Full-stack Symfony 7

ENTERPRISE · RICH DOMAIN

Modular monolith with Twig, Doctrine, Security and Forms. Fits B2B platforms, custom ERPs and internal portals where the domain is complex and the horizon goes beyond five years.

Teams of 5+ · 5-10 years in production

Headless API Platform

REST · GRAPHQL · OPENAPI

Symfony backend exposed as REST and GraphQL API from the same entity. Generated OpenAPI, Mercure for real-time and integrated JWT. Fits Next.js, Nuxt or mobile app frontends.

Sylius e-commerce

B2B · B2C · HEADLESS

Sylius on Symfony 7 as a headless e-commerce base. Catalog, cart, checkout and promotions with custom extension. Integration with ERP, PIM and European payment gateways.

Checkout · PIM · Multi-store

Microservices with Messenger

CQRS · EVENT-DRIVEN

Symfony as a bounded service with Messenger on RabbitMQ or Kafka. Commands, events and queries separated, idempotent workers and clear bounded contexts to decompose a monolith in phases.

TECHNOLOGIES

Symfony stack in production.

Symfony 7 as the framework, Doctrine for persistence, API Platform for headless exposure and Sylius as a product base. PostgreSQL, Redis and Messenger for data and messaging. PHPStan, PHPUnit and Composer in every repo.

03 · QUESTIONS

What teams ask before choosing Symfony.

Concrete answers about architecture, scaling, migration and how Symfony compares to other frameworks.

  • Symfony or Laravel?
    Symfony 7 fits systems with complex domain, large teams and a five-to-ten-year horizon: Doctrine, Messenger and decoupled components. Laravel covers MVPs and SaaS where time-to-market leads. We model the case and write the decision down in an ADR.
  • Does Symfony have LTS support for long-running projects?
    Symfony ships an LTS every two years with four years of total support: two of bugfixes and two of security patches. We build on the most recent active version and plan the upgrade to the next LTS within normal operations.
  • How does a Symfony application scale under real load?
    Stateless behind a load balancer, OPcache and preload for low latency, Redis for sessions and cache, Messenger on RabbitMQ or SQS for async, and Postgres read replicas. We operate on Kubernetes or managed services with OpenTelemetry and p95, RPS and error metrics.
  • What does it take to migrate a legacy PHP codebase to modern Symfony?
    We apply strangler fig: isolate modules, put Symfony 7 in front with selective routes and move domain by domain with characterization tests. Doctrine takes over the new model and the legacy retires without stopping the business. The scope is measured in sprints with progressive delivery.
  • Does Symfony fit microservice architectures?
    Symfony composes with MicroKernel and shrinks to the minimum per service. Messenger over RabbitMQ, Kafka or SQS wires the bounded contexts, API Platform exposes the contract and OpenTelemetry gives end-to-end tracing. It works to decompose monoliths in phases.
  • What quality practices apply to every Symfony project?
    PHPStan at max level, PHPUnit with domain coverage, Rector for automatic refactors and PHP CS Fixer in the pipeline. CI/CD with GitHub Actions or GitLab CI, automated deployments and OpenTelemetry observability from the first sprint.
