Migrating from monolithic rails

Mar 13, 2015Download as pptx, pdf1 like321 views

This document discusses migrating a monolithic Rails application to a more modular architecture by extracting the API into a separate Grape micro-framework. It notes that while Rails is nice for many things like routing, models, and persistence, extracting the API can improve performance, scalability, and make it easier to add other services over time. It encourages taking small, incremental steps towards this evolution by first moving the API into Grape and then potentially extracting other components.

Migrating from Monolithic Rails
by Danielius Visockas
Twitter: @DVisockas
v1

Desktop only
Extractions of patterns
History of Rails

Why Rails is nice:
● Routing
● Models (!)
● Persistence (migrations, schema)
● Sessions, cookies management
● Mailers
● Other stuff (rake tasks, assets pipeline, etc)

We had 2 apps
Main Rails app and Sinatra for the API

In the main app we used plain Rails
views and jQuery for the magic

Frontend magic
548 view files 84 javascript files
some files that would make sense

Late extraction costs more than early abstraction
Especially in frontend

Next thing: build an API
That’s where Ruby is the best tool

An opinionated micro-framework for creating REST-like APIs in Ruby.
http://intridea.github.io/grape
● Specifically for building API’s
● Minimal
● Fast (Grape: 2227 req/sec vs RailsAPI: 1111.42 req/sec) on 1.9.3

Other cool features of moving to
Grape
● Support from the community
● You already have models
● Documentation
● Easy integration into Rails

From evolution to revolution
● Small steps
● Reduced server load
● Easier to add other (micro-)services
● Easier scaling
● You can concentrate on one side of the app

Going mobile with RichFacesLukáš Fryč

The rise of portable devices last year shows how important is making applications compatible with mobiles. When it comes to web applications, JSF offers the same strong background for mobile development as it does for desktop applications: an extensible framework with a widely-accepted development model, allowing reuse of JSF programming skills and technologies on the mobile platform. RichFaces 4.1 goes behind concepts brought by JSF and provides developer with framework which makes your applications ready for mobile devices and offers you as rich component suite as for desktop environments. Lukas is going to show you how the RichFaces Showcase was turned into an application for portable devices, how a light-weight javascript framework was designed for making RichFaces applications mobile ready, the principles of an one-page application design and what are the necessary optimizations for making RichFaces applications run on mobile devices properly.

GraphQL over RESTBongwon Lee

The document discusses the evolution of API design from early standards like XML-RPC and SOAP to modern standards like REST and GraphQL. It outlines some limitations of REST APIs like underfetching and overfetching data through multiple requests. GraphQL is presented as a new API standard that was developed by Facebook to address these issues by allowing clients to fetch data from multiple resources through a single endpoint and request. Key features of GraphQL like declarative data fetching and a strong type system are also summarized.

RichFaces CDK: Rapid JSF Component DevelopmentLukáš Fryč

JSF component libraries provide you with a solid basis for building enterprise UIs as they are covering most common use cases. But what can you do in a case that no existing component fits your project requirements? There are many JavaScript component projects which offer together nearly infinite possibilities. But it might not be evident that leveraging these JavaScript frameworks is as easy as writing plain old HTML code, separating component and page development efforts. But how to wrap these components to fit into JSF eco-system? That’s exactly where RichFaces CDK comes into play.

Weighted Student Funding OverviewSharonne Navas

The document provides historical context on Washington state's weighted student funding formula prior to 1977, including additional funds allocated for specific student groups. It also describes how the current state salary schedule and staffing ratios were established in 1977 based on districts that regularly passed levies. The effects of the current funding system are that highest need schools tend to be taught by more junior teachers due to how allocation amounts are determined by teacher experience and education levels. Weighted student funding is proposed as an alternative to allocate dollars based on student needs rather than staffing characteristics, with the goal of closing achievement gaps. Seattle's early experience with weighted student funding showed disparities between high and low need schools but the system became too complex to sustain.

AI-proof your career by Olivier Vroom and David WIlliamsonUXPA Boston

This talk explores the evolving role of AI in UX design and the ongoing debate about whether AI might replace UX professionals. The discussion will explore how AI is shaping workflows, where human skills remain essential, and how designers can adapt. Attendees will gain insights into the ways AI can enhance creativity, streamline processes, and create new challenges for UX professionals. AI’s influence on UX is growing, from automating research analysis to generating design prototypes. While some believe AI could make most workers (including designers) obsolete, AI can also be seen as an enhancement rather than a replacement. This session, featuring two speakers, will examine both perspectives and provide practical ideas for integrating AI into design workflows, developing AI literacy, and staying adaptable as the field continues to change. The session will include a relatively long guided Q&A and discussion section, encouraging attendees to philosophize, share reflections, and explore open-ended questions about AI’s long-term impact on the UX profession.

Distributionally Robust Statistical Verification with Imprecise Neural NetworksIvan Ruchkin

Presented by Ivan Ruchkin at the International Conference on Hybrid Systems: Computation and Control, Irvine, CA, May 9, 2025. Paper: https://arxiv.org/abs/2308.14815 Abstract: A particularly challenging problem in AI safety is providing guarantees on the behavior of high-dimensional autonomous systems. Verification approaches centered around reachability analysis fail to scale, and purely statistical approaches are constrained by the distributional assumptions about the sampling process. Instead, we pose a distributionally robust version of the statistical verification problem for black-box systems, where our performance guarantees hold over a large family of distributions. This paper proposes a novel approach based on uncertainty quantification using concepts from imprecise probabilities. A central piece of our approach is an ensemble technique called Imprecise Neural Networks, which provides the uncertainty quantification. Additionally, we solve the allied problem of exploring the input set using active learning. The active learning uses an exhaustive neural-network verification tool Sherlock to collect samples. An evaluation on multiple physical simulators in the openAI gym Mujoco environments with reinforcement-learned controllers demonstrates that our approach can provide useful and scalable guarantees for high-dimensional systems.

Harmonizing Multi-Agent Intelligence | Open Data Science Conference | Gary Ar...Gary Arora

This deck from my talk at the Open Data Science Conference explores how multi-agent AI systems can be used to solve practical, everyday problems — and how those same patterns scale to enterprise-grade workflows. I cover the evolution of AI agents, when (and when not) to use multi-agent architectures, and how to design, orchestrate, and operationalize agentic systems for real impact. The presentation includes two live demos: one that books flights by checking my calendar, and another showcasing a tiny local visual language model for efficient multimodal tasks. Key themes include: ✅ When to use single-agent vs. multi-agent setups ✅ How to define agent roles, memory, and coordination ✅ Using small/local models for performance and cost control ✅ Building scalable, reusable agent architectures ✅ Why personal use cases are the best way to learn before deploying to the enterprise

Migrating from monolithic rails

1. Migrating from Monolithic Rails by Danielius Visockas Twitter: @DVisockas v1

2. Let’s look at Rails

4. Desktop only Extractions of patterns History of Rails

5. Let’s fast forward 10 years

6. Why Rails is nice: ● Routing ● Models (!) ● Persistence (migrations, schema) ● Sessions, cookies management ● Mailers ● Other stuff (rake tasks, assets pipeline, etc)

8. Story actually starts here

9. We had 2 apps Main Rails app and Sinatra for the API

10. In the main app we used plain Rails views and jQuery for the magic

11. Frontend magic 548 view files 84 javascript files some files that would make sense

12. Late extraction costs more than early abstraction Especially in frontend

13. && Your friends

14. Next thing: build an API That’s where Ruby is the best tool

15. Ruby API building tools

17. An opinionated micro-framework for creating REST-like APIs in Ruby. http://intridea.github.io/grape ● Specifically for building API’s ● Minimal ● Fast (Grape: 2227 req/sec vs RailsAPI: 1111.42 req/sec) on 1.9.3

18. Other cool features of moving to Grape ● Support from the community ● You already have models ● Documentation ● Easy integration into Rails

19. From evolution to revolution ● Small steps ● Reduced server load ● Easier to add other (micro-)services ● Easier scaling ● You can concentrate on one side of the app

20. Try it after 2 days
