It's possible to introduce real-time features to PHP applications without deep modifications of the current codebase.
Using WAMP you can build distributed systems out of application components which are loosely coupled and communicate in (soft) real-time.
There is no need to learn a whole new language, with the implications it has.
It also opens the door to write reactive, event-based, distributed architectures and to achieve easier scalability by distributing messages to multiple systems.
At Tuenti, we do two code pushes per week, sometimes modifying thousands of files and running thousands of automated tests and build operations before, to ensure not only that the code works but also that proper localization is applied, bundles are generated and files get deployed to hundreds of servers as fast and reliable as possible.
We use opensource tools like Mercurial, MySQL, Jenkins, Selenium, PHPUnit and Rsync among our own in-house ones, and have different development, testing, staging and production environments.
We had to fight with problems like statics bundling and versioning, syntax errors and of course the fact that we have +100 engineers working on the codebase, sometimes merging and releasing more than a dozen branches the same day. We also switched from Subversion to Mercurial to obtain more flexibility and faster branching operations.
With this talk we will explain the process of how code changes in ourcode repository end up in live code, detailing some practices and tips that we apply.

Building high performance microservices in finance with Apache ThriftRX-M Enterprises LLC
Apache Roadshow Chicago Talk on May 14, 2019
In this talk we’ll look at the ways Apache Thrift can solve performance problems commonly facing next generation applications deployed in performance sensitive capital markets and banking environments. The talk will include practical examples illustrating the construction, performance and resource utilization benefits of Apache Thrift. Apache Thrift is a high-performance cross platform RPC and serialization framework designed to make it possible for organizations to specify interfaces and application wide data structures suitable for serialization and transport over a wide variety of schemes. Due to the unparalleled set of languages supported by Apache Thrift, these interfaces and structs have similar interoperability to REST type services with an order of magnitude improvement in performance. Apache Thrift services are also a perfect fit for container technology, using considerably fewer resources than traditional application server style deployments. Decomposing applications into microservices, packaging them into containers and orchestrating them on systems like Kubernetes can bring great value to an organization; however, it can also take a very fast monolithic application and turn it into a high latency web of slow, resource hungry services. Apache Thrift is a perfect solution to the performance and resource ills of many microservice based endeavors.

Node.js BFFs - our way to the better/micro frontendsEugene Fidelin
To be able to implement new features in as little time as possible, we migrated our
monolithic Java-based frontends towards smaller Node.js BFFs (backend-for-frontend, BFF
pattern - create separate backend services to be consumed by specific frontend
applications).
Now we are close to the next step in our journey and adopt Micro-frontends architecture to
build our web apps as a composition of even smaller features which are owned by
independent teams

How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.

3. Agenda
• Concepts and foundations
• Real-time communication patterns
• Implementations
• Examples
4. Real-time
A system is said to be real-time if the total
correctness of an operation depends not only upon
its logical correctness, but also upon the time in
which it is performed
7. Criteria for real-time
• Hard – missing a deadline is a total system failure
• Firm – infrequent deadline misses are tolerable, but
may degrade the system's QoS. Results are NOT
usefulness after its deadline
• Soft – the usefulness of a result degrades after its
deadline, thereby degrading the system’s QoS
9. Soft real-time
Typically used to solve issues of concurrent
access and the need to keep a number of
connected systems up-to-date through
changing situations
10. Soft real-time use cases
• Live audio-video systems
• Users collaboration
• Messaging applications, etc…
• Real-time analytics
• Gaming
• Etc…
11. The road to 500 million
Symfony downloads
https://symfony.com/500million
12. Why adding a soft
real-time feature?
• To improve end-user experience
• Due to insufficient scaling capacity
16. WebSockets
• Full-duplex communication channels over a
single TCP connection
• Currently supported in most major
browsers
• Can be used by any client or server
application
17. HTTP/2
• Major revision of the HTTP
• Replacement for how HTTP is expressed
“on the wire”
• Focus on performance, end-user perceived
latency, network and server resource usage
18. The Mobile Internet
• Inestable connections
• HTTP & TCP slow-start are usually not a
good match for constantly dropped
connections
• Network interface kills battery
• Large responses + periodic polling = bad
26. RPC – Example 3
Communication between micro-services
Auth
Server
login(user)
Analytics Payments
track(user) process(order)
27. Publisher/Subscriber
• A peer subscribe to a topic
• Another peer publish a message about this
topic
• All publishers interested in the topic
receives the message
31. Not to be confused with WAMP:
”Windows + Apache + MySQL + PHP"
32. WAMP
• Open standard WebSocket subprotocol
• Provides two application messaging
patterns in one unified protocol
• Remote Procedure Calls
• Publish & Subscribe
33. WAMP Features
• Enables different technologies, processes,
machines, etc… to communicate with each
other, in soft real-time
34. WAMP Features
• Based on modern Web standards:
WebSocket, JSON and URIs
• Designed with first-class support for
different languages in mind (Polyglot)
35. Unified Application Routing
Routing of events (for PUB/SUB) and routing of
calls (for RPC) in one unified protocol
Caller CalleeDealer
Publisher SubscriberBroker
36. Dealer
• Routes calls from the caller to the callee
and routes back results or errors
• Callers and callee don’t know about each
other
• Applications using RPC benefit from these
loose coupling
Caller CalleeDealer
37. Broker
• Keeps a book of subscriptions
• Forward the events (messages) to all
subscribers
• Publisher are subscribers are loosely
coupled
Publisher SubscriberBroker
38. Unified Protocol
• When you combine a Broker and a Dealer
you get what WAMP calls a Router
Router Broker Dealer= +
39. The Big Picture
WAMP Router
(Dealer + Broker)
BrowserBrowserBrowserBrowser
Mobile
Clients
Services
40. Do we really need
another wheel?
How does WAMMP compare to other technologies
41. Criteria
• Pub/Sub
• RPC
• Routed RPC (not only point-to-point)
• Web native: run natively on the Web (without
tunneling or bridging)
• Cross Language
• Open Standard
44. WAMP Routers
• crossbar.io – Advanced, open-source, full
featured, supported by the creators of
WAMP
• Your own… It’s an open protocol
45. WAMP Ecosystem
• Thruway – library built in PHP that provides
both a client and a router
• Turnpike – router implemented in Go
• wamp.rt – router for NodeJS
• Erwa – router implemented in Erlang
56. Trade-off
• Situation that involves losing one
quality or aspect of something in
return for gaining another quality
or aspect
• It often implies a decision to be
made with full comprehension of
both the upside and downside of
a particular choice
57. Is PHP the right tool
for the job?
There is not simple answer
61. • A big ecosystem of thousands of useful
libraries and components easily installable
thanks to Composer
• Very powerful template engines, ORMs,
etc…
62. • We have implemented very powerful design
patters in PHP coming from Java and other
languages
• We have several thousands of high quality code
running on production
• We have invested multiple hours testing,
refactoring and improving the codebase
67. Upsides
• Possibility to introduce real-time features
without deep modifications in the current
codebase
• No need to learn a whole new language/
stack, with the implications it has
• Loosely coupled systems
68. Upsides cont…
• Opens the door to write reactive, event-
based, distributed architectures
• Scalability is easier to achieve by
distributing messages to multiple systems
70. The Stack
• crossbar.io used as the router (dealer+broker)
• PHP client gathers and publish events
• Silex/Symfony backend serve the data and
contains the biz logic
71. crossbar.io
• Networking platform for distributed and
micro-services applications
• Full implementation of the WAMP protocol
• Feature rich, scalable, robust and secure
• It takes care of the hard parts of messaging
so you can focus on your app's features
72.
73. Tips and Tricks
• WSS
• Deadlines
• Timeouts
• Retries with back-off, etc…
• Idempotency
74. Opinionated
Conclusion
• Understand core concepts and patterns,
technology is volatile
• Question everything: Why?, why not?
• Decide based on several factors: user
experience, scalability, feasibility, developer
experience, maintenance costs/debt, etc…
75. Don’t Stop Here
• gRPC – A high performance, open-source
universal RPC framework from Google
http://www.grpc.io/
• IoT, WoT, etc… – real world objects
connected to the wider internet
