- To provide a simple example of how to implement
Domain Driven Design
andMessaging Architecture
in PHP. - To show how to implement
CQRS
,Event Sourcing
andHexagonal Architecture
in PHP. - To show how to implement
Resilient
andObservable
Microservices
in PHP.
It does not really matter if we work in E-Commerce
, ERP
or Finance based systems
, we can be sure that system will be resilient, observable and maintainable in long term.
And we can achieve using principles of Message-Driven Systems
combined with Domain Driven Design
using patterns like CQRS
, Event Sourcing
and Service Bus
in PHP.
And to make it happen we will use Ecotone Framework
combined with Symfony
or Laravel
.
Ecotone is Message-Driven Framework for building resilient, business oriented systems in PHP.
Ecotone allows to build Microservices
and Event-Driven
systems in PHP with ease.
Thanks to foundation build around Message Driven Architecture, it allows to build Resilient
and Observable
systems in PHP.
On top of that it provides patterns from DDD like - Aggregates
, Domain Events
, Projections
, Sagas
, and more.
Ecotone integrates with Symfony
and Laravel
and allows you to connect Services seamlessly using Microservice
or Event-Driven
architecture.
In short Ecotone is a powerhouse to build reliable systems in PHP in a way that is maintainable, scalable and most importantly resilient.
Run docker-compose up -d
to start all services.
Go to Customer Service to report issue as a customer.
Whenever issue is reported, confirming email will be sent to the customer, which can be found Mailbox.
First time email is sent it's set up for failing, so you can get feeling of working with system that can recover from error messages using Ecotone Pulse.
From Backoffice Service you may start working on ticket, that was correlated with issue reported by customer.
You may also check Jaeger to get full overview of how communication looks like and how each component behave and what is happening.
- Ecotone - PHP Framework for building resilient, business oriented system in PHP
- Symfony - PHP Framework for building web applications
- Laravel - PHP Framework for building web applications
- RabbitMQ - Message Broker for asynchronous communication
- Ecotone Pulse - Monitor for any processing errors and recover from failed messages.
- OpenTelemetry with Jaeger - Distributed Tracing for monitoring and troubleshooting microservices-based distributed systems
Customer Service
isLaravel+Ecotone application
, where customers can report issues. This happens usingCQRS
combined withEloquent Models
.
- Whenever new issue is reported, email is send to the with confirmation. This happens using
Asynchronous Event Handlers
, which are backed byRabbitMQ
.
Backoffice Service
isSymfony+Ecotone application
, where employees can be registered and work on the tickets.
All issues reported by customers are synchronized toBackoffice Service
and are correlated with tickets.
The synchronization betweenCustomer Service
andBackoffice Service
is done usingEvents
andDistributed Bus
for cross service communication viaRabbitMQ
.
- Employees can work on the tickets provides information about the status. As we want to know full history, Tickets are
Event-Sourced
.
From Event Sourced tickets we build differentRead Model Projections
, which are used to display information about the ticket.
- The whole communication between Services is monitored and traced using OpenTelemetry with
Jaeger
.
