Docker has been a part of our development environments for long as of now. But its usage in production had not followed the same adoption curve, and it's instead rising only in the last years, mainly due to Kubernetes. But Kubernetes is not only a simple tool to port your containers into production, it goes beyond that! It lets (and forces) us developer embrace the twelve-factor approach, creating real cloud-native applications, where everything is parametrized and properly isolated. In this talk we'll see how a Symfony application can be easily packaged, parametrized and deployed using Docker, Kubernetes and Helm, up to the point of having one-click deployments of per-branch environments, a tool that makes review/QA of a feature really fast & easy.

Nowadays offering a REST API has become a must for most of the businesses. Offering a good documentation, validating properly the requests, having descriptive error messages, supporting multiple versions, retrieving data, persisting data, handling rate limitations and many other things can be not an easy task. This talk is a walk-through on how to build a rich, RESTful (Level 3 including HATEOAS) API for web applications using Symfony-related components and bundles. The result will be a standard, documented, validated and easy to maintain API, that users will enjoy and developers love to build.

Symfony Cache has been around for a few releases. But what is happening behind the scenes? Talk focuses on how is it working, down to detail level on Redis for things like datatypes, Redis Cluster sharding logic, how it differs from Memcached and more.

Even though you hear all these talks about scaling and infinite possibilities, the examples that truly match your use case are few and far between. So when we set out to make Nuvola (our greenfield Symfony application) use both sharding and a master slave approach at the same time, we faced a variety of issues and none of the solutions out there were a perfect match. We dealt with having Doctrine handle both features at the same time, possible delays in propagation from master to slave, and a whole class of bugs we may or may not have introduced with this change. Is this issue surfacing just now because of this change? Was it there all along and we just never noticed? This is not a story about how things look in a perfect world, this is about what we had, what we set out to do, and how we made it work.

Having to import a bunch of data is a common task and doing it efficiently is a difficult thing to do. In this talk I will go through an example and show you common limiting factors, how to identify issues and how to make bulk imports memory efficient and fast.

Why is API platform a way to go and the new standard in developing apps? In this talk, I want to show you some real examples that we built using API platform including a ticketing system for the world’s biggest bicycle marathon and a social network that is a mixture of both Tinder and Facebook Messenger. We had to tackle problems regarding the implementation of tax laws in 18 different countries, dozens of translations (including Arabic), multiple role systems, different timezones, overall struggle with a complicated logic with an infinite number of branches, and more.

Serverless services, like AWS Lambda, have been proven useful to solve a wide range of problems, and its use is growing rapidly. Recently, the possibility to use the PHP runtime in Lambda was added, so why not trying to use our favourite framework? How can we make the most from a serverless approach? What are pros and cons? In this session we will analyze the necessary steps to set up a Symfony4 project in Lambda and deploy it.
