From 0 to 100 - On prem Monolith to Distributed Function as a Service
Jack Liddiard, Resilient PLC

Cloud native, distributed systems, function as a service and machine learning have become the norm around the office in recent years.

With access to a variety of knowledge around micro-services in the cloud - the task has become almost instinctive. However few speak about the difficult journey from migrating an on premise monolith to a cloud native solution while sustaining full service.

In this talk I'll explain how Resilient sustained 1.3 billion minutes a year, 240 million calls a year and 60% emergency service traffic routing through us without losing a single minute of call time.

We will look at:
- The practicalities of moving from on prem to cloud
- Breaking out existing services to individual services and vertical teams
- Placing new and legacy services into the cloud while sustaining full service
- Monitoring and tracing in the cloud and on prem
- Hooks into existing system
- How the engineering team helped move a business from on prem to the cloud

All to detect fraud in sub 200 milliseconds.

Jack is a highly skilled, passionate senior software engineer specialising in Scala/Java. His core skills lie in distributed Scala/Java systems leveraging the bleeding edge of technology including Akka, Serverless & deep learning techniques to sustain and build a fraud detection at Resilient PLC.

Challenging the principles of Microservices
