This document provides an introduction to service oriented architecture (SOA). It discusses the evolution from procedural programming to object oriented programming to service oriented programming. In service oriented programming, services are well-defined, self-contained functions that communicate with each other via standard message formats. SOA is an architecture style that builds applications using services. The basic principles of SOA include being technology neutral, stateless, standardized, loosely coupled, reusable, consumable, abstracted, published, and having a formal contract.

Soa 6 service architecture components
The document discusses the key components of Service Oriented Architecture (SOA). SOA is based on coarse-grained services that expose their capabilities through standardized interfaces and messages. The core SOA components are:
1) Services which implement discrete pieces of application logic and are autonomous, reusable modules accessible via messages.
2) Service contracts which define the messages and interfaces that a service supports.
3) Endpoints which are addresses where services can be accessed.
4) Messages which are the units of communication between services in the form of requests and responses.
5) Policies which govern a service's behavior and are set externally to the service.
6) Service consumers which interact with

EKON20 Conference, November 2016
Monolithic rich Windows applications are not enough for our customers. We are often requested to provide a web front-end, or a REST server to be consumed by mobile or thin clients. Integrating n-Tier architecture to an existing project is challenging. Some good practices, based on industry standards and proven design patterns (like uncoupling or SOLID) can be mind-breaker for RAD developers. In this session, we will define some architectural aspects of SOA, ORM and MVC/MVVM, and what our Open Source mORMot framework offers to ease this transition.

This document proposes a view-based framework to model quality of service (QoS) in service-oriented enterprise systems. It notes that current QoS modeling is too technology-focused and ignores other perspectives like business needs. The research aims to balance viewpoints by constructing multiple views of QoS, modeling each as interacting goals, and using techniques like i* modeling to balance conflicts across views. This holistic approach would provide a more comprehensive QoS model for controlled enterprise systems compared to open internet-based service-oriented architectures.

Encapsulation, inheritance, and polymorphism are described as key principles of OOP. Common programming paradigms like procedural, object-oriented, functional, and declarative are also overviewed.
Service Oriented & Model Driven Architectures
The document discusses a seminar on combining Service-Oriented Architectures (SOA) and Model Driven Architectures (MDA). It first provides an overview of SOA and MDA individually, including their goals and characteristics. It then analyzes the similarities and differences between the two approaches when combining them. Some benefits are improved productivity and lower costs, while challenges include defining models and transformations between levels of abstraction. Overall, the document concludes that combining SOA with MDA's model-driven approach can provide benefits like business agility if key issues like semantics and metadata modeling are adequately addressed.
Arquitectura orientada a servicios
Service-oriented architecture (SOA) is a design paradigm that defines how systems can communicate with each other through services. SOA defines software in terms of services that are made available over a network and used by clients to exchange data with transaction systems, applications, and other services. It provides a standardized way of exposing application functionality for use by third party systems and applications.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

SOA - Service Oriented Architecture ( Basic Concept & Principle )
- 1. Service Oriented Architecture An Introduction Rajeev Tiwari
- 2. Evolution of SOA Procedural Programming Object Orient Programming Service oriented Programming
- 3. Procedural Programming Function is everything Limitation: How to reuse the same code? Difficulties in code Management.
- 4. Object Orient Programming Classes and Object are everything Limitation: how to communicate between applications, especially when they have been written using different languages or technologies Object oriented principles - Abstraction, Encapsulation, Inheritance, and polymorphism OOP increased the reusability and thus improved the code management
- 5. Service oriented Programming Service is everything A service is a function that is well-defined, self-contained, and does not depend on the context or state of other services Services communicate with each other using messages. Messages are standard formats which everyone (every service) can read and understand
- 6. Service oriented Programming • Service Provider • Service Repository • Service Consumer
- 7. Patterns In simple words Pattern is a solution to a problem in a context Architectural Patterns Architectural Pattern is something which solves our problem at sub system level or in short module level. Design Patterns Design pattern talk about problems at class or function level
- 8. What is SOA? SOA or Service oriented architecture is an architecture style for building business applications by means of services
- 9. • Technology neutral • Statelessness • Standardized - WS* • Loose coupling • Reusability • Consumable • Abstracted • Published • Formal Contract Basic Principles of SOA
