This document discusses REST technology and how to implement it in Python. It introduces REST and compares it to SOAP. It then outlines the 6 steps to create a RESTful web service: 1) separate client and server responsibilities, 2) make the server stateless, 3) allow caching, 4) use a layered system with intermediaries, 5) implement a uniform interface using URIs, representations, status codes and headers, and hypermedia, and 6) optionally allow code on demand. The document concludes by mentioning JSONSchema and stating that examples of implementing REST in Python will follow.

Using React.js to extend your CMS - Nicola Richardson
The range of CMSs available gives us a huge amount of variety with the possible ways to architect and build content-driven websites. However, even though most platforms support custom templating and theming, they aren't necessarily the best tools for delivering a modern front-end experience. Sometimes we want the front-end of our websites to do things that CMSs aren’t designed to do.
So what if, instead, we used the best technologies for the task: taking the data-store backend of the CMS, and plugging it into a flexible, decoupled frontend? This talk will focus on how JS frameworks or libraries, such as React.js, can be bolted onto headless CMSs to provide the immersive experience that we want our apps and websites to have, without needing to compromise on the complexity of the data structure on the backend. Using React.js and Drupal 8 as an example, we’ll take a look at a project currently in development where both technologies have been combined, and explore how it works, why it works and what you need to think about when trying this for yourself.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

The Art of the Pitch: WordPress Relationships and SalesLaura Byrne
Clients don’t know what they don’t know. What web solutions are right for them? How does WordPress come into the picture? How do you make sure you understand scope and timeline? What do you do if sometime changes?
All these questions and more will be explored as we talk about matching clients’ needs with what your agency offers without pulling teeth or pulling your hair out. Practical tips, and strategies for successful relationship building that leads to closing the deal.
Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

23. Client-Server
The client requests data for consumption or updates features that are on the server.
1
Why?
● Responsibilities division;
● Scalability; and
● Independent evolution.
24. Stateless
The Server must not keep state sessions. All necessary info for processing must be in
client's request.
2
Why?
● Scalability; and
● Reliability.
28. Layered System
The service must be layered, not allowing communication between client and the end
service. The system must be Intermediaries to respond requests instead of the end
server.

Tecnologia REST em Python - por Allex Lima
Interação com público: Quem já utilizou com REST? / Será? / Quem aqui nunca utilizou? Ok, sem problemas… é realmente muito comum se confundir sobre o real conceito REST, proposto pelo Roy Fielding, em sua dissertação de doutorado. Isso é algo tão comum que existem até memes na web sobre isso.
REST (Estado Representacional de Transferências) é um modelo arquitetural para sistemas com suporte à rede que foi proposto por Roy Fielding em 2000, em sua dissertação de Doutoramento.
Além disso, o modelo REST foi desenhado para trabalhar sobre o protocolo HTTP. Daí a liberdade de escolher o formato de representação do pacote de informação: json, xml, bytes, text etc
É bastante comum encontrar aplicações REST que estão relacionadas a Serviços Web e APIs, como a do Twitter e Telegram, por exemplo.
Roy Fielding: Alguém lançou uma nova API REST / Vamos ver!!
Roy Fielding: Hmm… Apenas um outro RPC baseado em HTML
Porém REST não é a única tecnologia existente quanto estamos falando de transferência de dados cliente-servidor. Dito isso, quais são suas principais concorrentes e por que ela se sobressai? Bem...
Nós temos o SOAP que, diferentemente do REST, não é um modelo ou especificação, mas sim, um protocolo. O SOAP possui, apenas, o XML como padrão para troca de dados cliente-servidor, porém pode ser implementado com RPCs (Remote Procedure Calls) ou através do HTTP. Bom, o que pode-se observar aí?! É que o SOAP não te permite estruturar o formato das informações que ele trabalha em outras além do XML, de forma a deixar o programador restrito ao XML. Ok… Mas e daí? Bom, hoje em dia temos o JSON que é, na maioria das vezes, potencialmente mais leve que dados no formato XML. Isso é tão interessante, que se observamos um comparativo de pesquisas no Google entre REST e SOAP..
Iremos observar que, nos últimos 5 anos, a procura pelo termo SOAP (em relação à tecnologia/protocolo), tem caído muito, em relação ao REST. Isso PODE significar que a comunidade de desenvolvimento web está mais interessada em tecnologias mais flexíveis, como REST.
