Editor's Notes
- I’ve been in development for 20 years Around half of which have been in the integration space I’ve been a senior consultant at Mexia for 3 great years now. Has the professional picture they took of me which I’ll never change because I’ve got so much less grey hair! Mexia concentrate solely on solving Integration problems. We analyze, architect, code, test and operate solutions built on Microsoft technologies those experiences on a recent project are the basis of todays talk
- Context – Business problem we solved with microserevices & also the Technology change we made at the bank we worked with This was a large undertaking for the bank which provided an opportunity to drive change In the way they deliver software Therefore I’ll explain our approach to: Design – Microservices & DevOps as a solution Build – Demonstration of creating a c# micoservice Deploy – Automation & Zero downtime Run – Resilience & Operational monitoring
- So today I’ll be showing Mexias approach to implementing the New Payments Platform (NPP) banking industry initiative There’s several parts to NPP but this diagram describes the inward payment process
- Desires the bank expressed to us during our 6 year relationship with them
- Although familiar to many in the audience the way we built and delivered this project was a little mind blowing for the bank compared to previous projects
- Explaining the architectural patterns used, our development & testing approach, hosting platform and choice of operational tools. The way we built and delivered this project was a little mind blowing for the bank compared to previous projects
- Provisioning via template. 6 mins to create a a Production ready cluster of 5 Windows Server machines We need a micro service hosting platform that can…
- As we do more of this we shall extend to BDD tests, team city, and octopus
- Why is Automation important with Microservices. One of the banks desires is to get to prod quickly. This can only be achieved with consistent automation Develop – Vanilla code Review – TFS /VSTS Build – Jetbrains Team City Test - Specflow BDD. Execuatble specifications. HTML report from BDD tests Analyse - Security and Code Analysis - best practices. There’s not the time for manual reviews Deploy – Dedicated deployment tool. Stores configuration, shows versions and environments and allows for a repeatable reliable process in every environment Service fabric performs rolling deployments, and will roll them back if there’s any issue

- Highlight the challenges with Microservices via a demo with Simulated Payments Need to aggregate logs and correlate – SEQ Appdynamics - Understand the physical layout, dynamically generated through agents inspecting the deployed components. Monitoring proactively showing errors and reduced performance Flight recorder to make sense of the business data that is flowing through the system – show screen shot
- This approach is changing the way the bank is delving software and business value Consistency from design to logs. Same name for everything. Instantly recognisable Patterns so that code generation can be employed as well as templating builds and deploys, leading to a consistent deployment pipeline Aggregation and correlation are vital to piece together a flexible Event architecture Microservices and good hosting platform removes code complexity Automation speeds time to production and ensures quality
