These rules make it easier to test your code\, as well as being a good fit for incorporating Domain- Driven Design. In this talk\, we'll look at how Hexagonal Architecture dif fers from typical architectures. We'll then dive into how Hexagonal Archit ecture leverages the idea of Separation of Concerns to make testing easier . We'll see how the architecture uses Ports &\; Adapters (another name for this architecture) to improve the design by clearly defining how exter nal resources connect to the core of our application's logic. \n\n \n\n Te d M. Young \n\n Ted M. Young (known as JitterTed on social media) is a Jav a trainer\, coding coach\, speaker\, and author. He's been in software dev elopment for over 30 years\, doing eXtreme Programming since 2000. Ted has worked for eBay\, Google\, Apple\, and Guidewire Software. He is now an i ndependent educator\, helping those new to the industry and experienced fo lks increase their joy in coding by making code more testable. Ted's favor ite techniques are test-driven development\, refactoring\, domain-driven d esign\, and Hexagonal Architecture. \n\n \n https://twitter.com/jitterted \n https://www.subscribepage.com/maketestable \n \n\n \n\n Event Sourcing and CQRS on Azure Functions \n\n In this talk I outline a system built usi ng Azure serverless functions and event grid\, the CQRS architecture and w ith the underlying entity storage being by event sourcing. The prototype s hows how this allows you to assemble a highly performant\, geographically distributed system which scales up and down rapidly for an extremely small cost. \n\n CQRS is an application design pattern (or architecture) that d iffers from single model architectures (like MVC or MVVM) in that the part s of the system responsible for changing the state of the system (the Comm and side) is entirely separate to the parts of the system responsible for getting the state of the system (the Query side). \n\n Event Sourcing is a data architecture that flips the way we store data on its head. Instead o f storing the state of any given object as it currently is and updating th at state\, we instead store the complete history of every change that has occurred to the object and allow us to derive the state of the object by r unning code known as a projection over that event history. \n\n Azure Even t Grid is a set of connected technologies provided by Microsoft as part of their Azure cloud which are designed to facilitate an event-driven archit ecture. It consists of event triggers that can be set up to either fire on a state change event and these triggers are linked by the Event Grid to r oute the events from their trigger to a destination - and azure serverless function. \n\n Merrion-Duncan Jones \n\n A .NET developer with a backgrou nd in the financial services industry. He has a personal interest in highl y scalable systems\, which has lead to Event Sourcing (by way of CQRS)\, a nd has developed a Visual Studio plug-in to for creating CQRS and Event So urcing based systems via a visual interface. \n\n \n https://twitter.com/M errion \n \n LAST-MODIFIED:20220811T095903 LOCATION:Microsoft Teams Meeting ORGANIZER:mailto:noreply-calendar@tito.io SUMMARY:June 16 2022 NE Bytes - More Testable Code with the Hexagonal Archi tecture + Event Sourcing and CQRS on Azure Functions URL;VALUE=URI:https://ti.to/ne-bytes/june-2022-hexagons-and-event-sources URL;VALUE=URI:https://ti.to/ne-bytes/june-2022-hexagons-and-event-sources END:VEVENT BEGIN:VEVENT DTSTAMP:20260619T091851Z UID:XEEGEQ1046270 DTSTART;TZID=Europe/London:20220616T183000 DTEND;TZID=Europe/London:20220616T210000 CLASS:PUBLIC CREATED:20220506T110541 DESCRIPTION:## NE Bytes June 16 2022\n### 18:30 - 21:00 BST\n\nJoin us for our next event of 2022 with two awesome talks and two awesome speakers.
