Cloud Native at a 150 year old Retail Institution - the good the bad and the ugly (Simon Perry, Sainsburys)
I'm going to talk about our Cloud Native journey at Sainsbury's. Our evolution through cloud technologies. What works for us. Some trials and tribulations. Some pitfalls.

I've been described as "A rare mix of engineering knowledge and great people skills who's not afraid to roll his sleeves up & get involved". I've had a long and varied career in Tech. I've started my own businesses and done all sorts job in between from development to administration. I've never lost my love for learning new technology. I'm currently a Senior Engineering Manager at Salisbury's who's responsible for our Cloud Engineering function and several teams.
Architectural Caching Patterns for Kubernetes (Rafał Leszko, Hazelcast)
Kubernetes brings new ideas on how to organize the caching layer for your applications. You can still use the old-but-good client-server topology, but now there is much more than that. This session will start with the known distributed caching topologies: embedded, client-server, and cloud. Then, I'll present Kubernetes-only caching strategies, including:
- Sidecar Caching
- Reverse Proxy Caching with Nginx
- Reverse Proxy Sidecar Caching with Hazelcast
- Envoy-level caching with Service Mesh"

Cloud software engineer at Hazelcast, author of the book "Continuous Delivery with Docker and Jenkins", trainer, and conference speaker. Rafał specializes in Java development, Cloud environments, and Continuous Delivery. Former employee in a number of companies and scientific organizations: Google, CERN, AGH University, and more.

Securing DevOps CI/CD Pipelines in the Cloud – 2021 Update (Jesus Escolar, Exelerys)
Through DevSecOps and SecDevops we have attained an new paradigm: Newer Threats on CI/CD environments.
We think, we develop, we build, but do we secure?
What’s the integration between CI/CD and Containers/Microservices?
What are the existing threats?
How do you mitigate them?
(This is an advanced presentation for DevOps where the audience needs to understand the CI/CD framework by heart)
