Download as pptx, pdf2 likes1,872 views
ASP.NET Web API is a framework that allows developers to build web APIs that embrace HTTP and help developers create RESTful services. It provides functionality for basic CRUD operations with HTTP methods, model binding, routing, validation, filtering, formatting responses, dependency injection, authorization, and OData queries. While not strictly REST itself, Web API can be used to build RESTful APIs and services as the web shifts from traditional sites to being powered by APIs.

Deployment taken seriously with Octopus Deploy and TeamCityTomas Jansson Tomas Jansson presented on how to implement continuous deployment using Octopus Deploy, TeamCity, and PowerShell. The goal is to have an automated deployment process that builds, tests, and deploys code changes from version control to environments multiple times a day. TeamCity is used for continuous integration to build and run tests on code changes. Octopus Deploy provides a dashboard to manage deployments to environments like QA and production. It supports promotion of deployments between environments using a NuGet package. PowerShell scripts are run during the deployment process for tasks like configuration transformations. A demo showed how these tools can be configured to achieve continuous deployment.
State or intent
State or intentTomas Jansson 1) Event sourcing stores the history of an application as a sequence of events, rather than storing the current application state. This allows testing by replaying events and integrating systems by subscribing to the stream of events.
2) In event sourcing, an event represents something that happened in the past, such as a customer moving or an order being placed. Applications can be tested by replaying events to ensure the correct outcome occurs.
3) Event sourcing avoids the impedance mismatch between objects and databases since events are part of the domain model. Applications can be rebuilt by replaying all events to reconstruct the state.
NServiceBus workshop presentation
NServiceBus workshop presentationTomas Jansson The document discusses NServiceBus, a service bus framework for .NET, emphasizing messaging, queues, and service-oriented architecture (SOA). It outlines key concepts such as the fallacies of distributed computing, the differences between a bus and a broker, and provides guidelines for messaging patterns, message handling, and unit testing including sagas. Practical exercises are included to reinforce the learning of these concepts.

High Availability On-Premises FME Flow.pdf
High Availability On-Premises FME Flow.pdfSafe Software FME Flow is a highly robust tool for transforming data both automatically and by user-initiated workflows. At the Finnish telecommunications company Elisa, FME Flow serves processes and internal stakeholders that require 24/7 availability from underlying systems, while imposing limitations on the use of cloud based systems. In response to these business requirements, Elisa has implemented a high-availability on-premises setup of FME Flow, where all components of the system have been duplicated or clustered. The goal of the presentation is to provide insights into the architecture behind the high-availability functionality. The presentation will show in basic technical terms how the different parts of the system work together. Basic level understanding of IT technologies is required to understand the technical portion of the presentation, namely understanding the purpose of the following components: load balancer, FME Flow host nodes, FME Flow worker nodes, network file storage drives, databases, and external authentication services. The presentation will also outline our lessons learned from the high-availability project, both benefits and challenges to consider.

Editor's Notes
- #3: Hej, jag heter Tomas
- #6: Embracing – har en veldigt enkel programmeringsmodell for å komma åt og sette saker relatert til httpLightweight – inte så mycket statiskt kontext som vi er vana med fra WebFormsHelt enkelt et bra verktøy for å bygge Web APIs, det må ikke vara publika, du kan ha desse i stedet for WCF!!!Det var førr WCF Web API, men det passade bedre in i ASP.NET så nå er det der
- #7: REST er noe som du må sørge for, bare fordi at du bruker et rammeverk som gjør det letter å bygge RESTful services så betyr det ikke at det blir det per automatik
- #8: Level 0: Communication over HTTP, no use of resources. For example SOAPLevel 1: Introducing resources, but still carrying «verbs» in the messages, most of the «rest» services are hereLevel 2: Introducing verbsLevel 3: HATEOS (Hypermedia as the engine of application state), communicating state and possible steps
- #11: Also some kind of reach.Other make money for you, if you have the right model
- #12: Internet skalar, så borde også vi. Gjenom å bruke samme typ av arkitektur så øker vi våra chansar at kunna skalera braMåste koppla isär våra appliaktioner mer når saker hamnar i cloudet
- #16: ASP.NET Web API finns demos og forklaringerDemo project kommer med magisk branching graf
