Serverless architectures let you build and deploy applications and services with infrastructure resources that require zero administration. In the past, you had to provision and scale servers to run your application code, install and operate distributed databases, and build and run custom software to handle API requests. Now, AWS provides a stack of scalable, fully-managed services that eliminates these operational complexities.
In this session, you will learn about the benefits of serverless architectures and the basics of the serverless stack AWS provides. We will also walk through how you can use serverless architectures for everything from data processing to mobile and web backends.
Ajax is a type of asynchronous programming that allows web pages to be updated asynchronously by exchanging data with a web server behind the scenes without interfering with the display and behavior of the existing page. It allows parts of a web page to be updated without reloading the entire page by communicating with the server in the background. This creates a more interactive and responsive experience for the user who can continue to interact with the page while waiting for new data to load.

SoapUI is a free and open source tool for testing web services. It allows users to create test suites, test cases, and test steps to test web services. Tests can be data driven using external data sources. SoapUI displays requests and responses in different formats and has reporting capabilities. It also supports mocking web services to test against prior to implementation.
Model View Controller (MVC) is a design pattern commonly used for web development that separates an application into three main components: the model, the view, and the controller. The model manages the behavior and data of the application. The view displays the user interface. The controller interprets user input and performs interactions between the model and view. Some key aspects of MVC include controllers handling requests and loading views, models containing business logic and data access, and views displaying information to the user. MVC promotes separation of concerns and makes applications more modular, reusable, and testable.
This document introduces Ruby on Rails (RoR) as a web development framework. It discusses key RoR concepts like MVC architecture, Active Record for object-relational mapping, and migrations for managing database changes. It provides resources for learning RoR, including downloading Ruby and Rails, using version control systems like Subversion, and recommended books and articles. The document emphasizes that RoR aims to increase productivity through conventions over configuration and generating code through scaffolds and templates.
API proxy auto discovery with MuleSoft API Gateway allows APIs to be automatically discovered and registered on the Anypoint Platform when deployed to an API Gateway paired with an organization. This saves the effort of manually registering APIs through the web interface each time and reduces human error. The auto discovery functionality kicks in when a special XML tag is added to the API proxy configuration in Anypoint Studio before deployment, which then registers the API details on the Anypoint Platform.
This document summarizes an AWS User Group Italy meeting presentation about AWS Lambda.
AWS Lambda allows writing code to automatically run in response to events, allowing building applications from small functions that are triggered by changes to data in AWS services. It provides an easy way to run code without having to manage infrastructure. Lambda functions can be triggered by events in services like S3, DynamoDB, and Kinesis. With Lambda, the focus is on writing business logic rather than managing servers. Lambda automatically scales as needed to handle event loads, and customers pay only for the compute time used rather than having to pay for unused capacity. A preview of Lambda is open for people to try it out with support for S3, Kinesis and Dynam
The document discusses the Model-View-Controller (MVC) pattern and Flux architecture. MVC faces problems as applications grow in size and complexity, with multiple controllers and views potentially manipulating the same model. Flux aims to address this by having a unidirectional data flow where all actions are dispatched through a central dispatcher. While simpler initially, Flux applications can also become confusing as data flows grow more complex. The key difference is that Flux maintains a higher level of predictability through its single-directional data flow approach.
React js is a JavaScript library created by Facebook in 2013 for building user interfaces and rendering UI components. It uses a virtual DOM to efficiently update the real DOM and allow building of reusable UI components. React code can be written directly in HTML or using JSX syntax and by setting up a React app with Node.js and NPM. Components are the building blocks of React and can be class or function based. Props and state allow passing data to components and re-rendering components on state changes.

Mule can run web applications using its embedded Jetty container. This allows a web application deployed in Mule to interact with Mule flows. For example, a web page can collect data from a user and pass it to a Mule flow backend service for processing, like inserting into a database. The Mule service can then return a response back to the web page. This demonstrates how a web application hosted in Mule can seamlessly interact with Mule flows and services.
Flux is an architecture for building JavaScript applications that promotes unidirectional data flow. The key elements of Flux are the Dispatcher, Stores, and Views. The Dispatcher centralizes the flow of data and dispatches actions to the Stores. Stores contain application state and logic. Views are React components that subscribe to Stores and listen for changes to re-render. Actions define activities and are dispatched by action creators through the Dispatcher to the Stores to update state.
This document discusses using Drools, a business rules management system, with Mule to execute business rules in applications. It provides an example of creating a simple Mule application that uses a .drl file to define rules to determine a warehouse destination based on a randomly generated weight variable. The application is deployed to a Mule standalone server and the rules are executed by the Drools component to set the destination variable according to the rules.

This document discusses the limitations of traditional MVC architecture and proposes using entities to address these issues. It notes that models have become too large and complex in MVC, containing business logic and handling of multiple tables and services. This has led to business logic leaking into controllers. The document proposes using entities that represent schemas and act as data transformers, operation handlers, and switches to help decouple and separate concerns. Entities are inspired by the service layer pattern and aim to provide human readable APIs, normalize inputs and outputs, and handle higher level operations.

Divide and Conquer: Easier Continuous Delivery using Micro-ServicesCarlos Sanchez
Docker has revolutionized the way people think about applications and deployments. It provides a simple way to run and distribute Linux containers for a variety of use cases, from lightweight virtual machines to complex distributed micro-services architectures.
Containers allow to run services in isolation with a minimum performance penalty, increased speed, easier configuration and less complexity, making it ideal for continuous integration and continuous delivery based workloads.
But testing a distributed micro-services architecture is no easy task, requiring a shift in mindset and tooling to accommodate the new architecture.
We will provide insight on our experience creating a Jenkins platform based on distributed Docker containers running on Apache Mesos and Marathon, applicable for all types of applications, but specially Java and JVM based ones.

The document compares two approaches to handling business logic in transactional applications: the NoPlsql approach and the SmartDB approach. The NoPlsql approach treats the database as only a persistence layer, putting business logic in application code. The SmartDB approach implements business logic directly in the database using SQL and PL/SQL. An experiment found that for the same task, a SmartDB implementation using stored procedures was over 3 times faster and used half the database CPU resources compared to a NoPlsql implementation using Java and JDBC. This is because every SQL statement incurs networking and database entry costs in NoPlsql, while SmartDB SQL statements leverage existing database sessions.

Divide and Conquer: Easier Continuous Delivery using Micro-ServicesCarlos Sanchez
This document discusses using microservices for easier continuous delivery. Some key points discussed include:
- Microservices involve developing an application as a suite of small services that communicate lightly and deploy independently.
- Benefits include organizing around business capabilities, decentralized governance and data management, and infrastructure automation.
- Continuous deployment requires automation at all stages including monitoring, reacting to problems, and preventing problems.
- Techniques like blue-green and canary deployments allow deploying without downtime. Monitoring is also important for taking proactive actions.
- Designing infrastructure as "cattle" rather than "pets" and embracing failure are discussed as important principles. Stateful services and ensuring resilience and self-healing

UI5con 2024 - Bring Your Own Design SystemPeter Muessig
How do you combine the OpenUI5/SAPUI5 programming model with a design system that makes its controls available as Web Components? Since OpenUI5/SAPUI5 1.120, the framework supports the integration of any Web Components. This makes it possible, for example, to natively embed own Web Components of your design system which are created with Stencil. The integration embeds the Web Components in a way that they can be used naturally in XMLViews, like with standard UI5 controls, and can be bound with data binding. Learn how you can also make use of the Web Components base class in OpenUI5/SAPUI5 to also integrate your Web Components and get inspired by the solution to generate a custom UI5 library providing the Web Components control wrappers for the native ones.
UI5con 2024 - Boost Your Development Experience with UI5 Tooling ExtensionsPeter Muessig
The UI5 tooling is the development and build tooling of UI5. It is built in a modular and extensible way so that it can be easily extended by your needs. This session will showcase various tooling extensions which can boost your development experience by far so that you can really work offline, transpile your code in your project to use even newer versions of EcmaScript (than 2022 which is supported right now by the UI5 tooling), consume any npm package of your choice in your project, using different kind of proxies, and even stitching UI5 projects during development together to mimic your target environment.
Consistent toolbox talks are critical for maintaining workplace safety, as they provide regular opportunities to address specific hazards and reinforce safe practices.
These brief, focused sessions ensure that safety is a continual conversation rather than a one-time event, which helps keep safety protocols fresh in employees' minds. Studies have shown that shorter, more frequent training sessions are more effective for retention and behavior change compared to longer, infrequent sessions.
Engaging workers regularly, toolbox talks promote a culture of safety, empower employees to voice concerns, and ultimately reduce the likelihood of accidents and injuries on site.
The traditional method of conducting safety talks with paper documents and lengthy meetings is not only time-consuming but also less effective. Manual tracking of attendance and compliance is prone to errors and inconsistencies, leading to gaps in safety communication and potential non-compliance with OSHA regulations. Switching to a digital solution like Safelyio offers significant advantages.
Safelyio automates the delivery and documentation of safety talks, ensuring consistency and accessibility. The microlearning approach breaks down complex safety protocols into manageable, bite-sized pieces, making it easier for employees to absorb and retain information.
This method minimizes disruptions to work schedules, eliminates the hassle of paperwork, and ensures that all safety communications are tracked and recorded accurately. Ultimately, using a digital platform like Safelyio enhances engagement, compliance, and overall safety performance on site. https://safelyio.com/

Hand Rolled Applicative User ValidationCode KataPhilip Schwarz
Could you use a simple piece of Scala validation code (granted, a very simplistic one too!) that you can rewrite, now and again, to refresh your basic understanding of Applicative operators <*>, <*, *>?
The goal is not to write perfect code showcasing validation, but rather, to provide a small, rough-and ready exercise to reinforce your muscle-memory.
Despite its grandiose-sounding title, this deck consists of just three slides showing the Scala 3 code to be rewritten whenever the details of the operators begin to fade away.
The code is my rough and ready translation of a Haskell user-validation program found in a book called Finding Success (and Failure) in Haskell - Fall in love with applicative functors.

- Code Complexity
- Code Duplication (breaking DRY principle)
- Code changes becomes difficult
- Scary unit test (Bloated unit test)
8. So, Again, why :
“Thin”
