Grace is a Developer Advocate at IBM, working with Open Liberty, MicroProfile and Cloud Technologies. She has been with IBM since graduating from Exeter University with a Degree in Biology. Grace enjoys bringing a varied perspective to her projects and using her knowledge of biological systems to simplify complex software patterns and architectures. As a developer advocate, Grace builds POC’s, demos and sample applications, and writes guides and tutorials. She is a regular presenter at international technology conferences and has recently authored a book on reactive systems. Grace also has a keen passion for encouraging more women into STEM and especially Technology careers.
Mother Nature has had millennia to build up its defences to the many potential hazards and attacks it may face. So, given its wisdom and expertise on this subject, what can we as software developers learn from it and bring back to the evolution of our own application’s security? In this session we’ll explore where software and biology overlap when it comes to security and lessons we can learn from nature to improve our own application security.
How does one choose to architect a system that has a Microservice / REST API endpoints? There are many solutions out there. Some are better than others. Should state be held in a server side component, or externally? Generally we are told this is not a good practice for a Cloud Native system, when the 12-factor guidelines seem to be all about stateless containers, but is it? It’s unclear and this confusion may lead to poor technology stack choices that are impossible or extremely hard to change later on as your system evolves in terms of demand and performance.
While stateless systems are easier to work with, the reality is that we live in a stateful world, so we have to handle the state of data accordingly to ensure data integrity beyond securing it.
We will examine and demonstrate the fundamentals of a Cloud Native system with Stateful Microservices that’s built with Open Liberty and MicroProfile in Kubernetes
