Alfredo Muñoz

Vaughn Vernon has a conversation with Alfredo Muñoz regarding the transformation and modernization within banks, why it's so urgently needed, and how efforts can be successful. Their discussion encompasses BIAN, Domain-Driven Design, Data Mesh, and why focusing on business capabilities as business, service, events, and data domains is critical. We address why banks are so resistant&nbsp;to change but why they must learn a new mindset in order to both survive and flourish in the age of cloud and digital&nbsp;banks. For example, a bank transaction that has 1,000 COBOL calls will never work in the cloud, nor will a transaction that makes 100 API calls. How can new technologies and approaches to software development help banks, insurance, airlines, telecom, and other industries that heavily rely on mainframe power successfully switch out of the old status&nbsp;quo? Alfredo is an Enterprise Architect, and Banking Transformation Expert with more than 25 years of experience in large scale banking transformations in Europe, Asia and Latam, always involving first tier banksHe currently works in the Global Center of Excellence for Banking and Financial Market at IBMDuring the past years he has developed the methodology for the modernization of corebanking systems, including the adoption cloud infrastructure in coexistence with legacy systems, the BIAN Industry Standards, the industrialization and standardization of the design and development processes and the use of low code development frameworks with the primary objective to deliver transformation at scale, as required for large Financial Institutions.He has authored leading points of view, methods and assets on core systems transformation to Cloud.&nbsp; <a href="https://www.fintechna.com/authors/alfredo-mu%C3%B1oz-r%C3%ADos/" rel="noopener noreferrer" target="_blank">https://www.fintechna.com/authors/alfredo-muñoz-ríos/</a><a href="https://www.linkedin.com/in/alfredomunoz/" rel="noopener noreferrer" target="_blank">https://www.linkedin.com/in/alfredomunoz/</a>

From Sustainable Architecture to Domain-Driven Transformation

Fran Méndez

Vaughn and Fran meander through the topics AsyncAPI and Event-Driven Architecture using Fran's "thinking out loud" style. They examine the motivation for AsyncAPI, which rescued a startup product team from prolific boilerplate infrastructure code. Every microservice they created suffered from enormous amounts of repeated code, which only got worse with frequent exponential growth of microservices. They discuss other areas such as inter-service shared AsyncAPI documents, versioned schema definitions, topic naming with blended message (e.g. command and event) names,&nbsp;topic versioning pros and cons, YAML vs KDL, add-on tools and templates, and how all these influence productivity. Fran is the founder of the AsyncAPI Initiative and also works as Director of Engineering at Postman. In his spare time, he enjoys practicing different sports and disciplines, especially those related to circus.
