2025 was a busy year for resilience talks – together with Adrian Bere from my team, we delivered the session Mastering resilience at every layer of the cake, at two events. The first stop was the AWS Summit Poland held on the 6th of May at the International Congress Centre in Katowice. Having spoken in Poland before, it is always a pleasure to come back and connect with the Polish tech community. A few months later, Adrian and I were back on stage at the AWS Cloud Day Prague.
A fun side note – the Poland Summit coincided with the Romanian National elections, so I made a stop at the Romanian Embassy to cast my vote. It was the second time I voted abroad, and it felt great to exercise that right while also being on the road for a conference.
Mastering resilience at every layer of the cake
In our session we used the analogy of a cake to explain how resilience needs to be addressed at every layer of the stack – from the AWS foundation (Availability Zones, Regions, global services) through the infrastructure layer (operating systems, databases) all the way up to the application layer. We covered how cloud resilience differs from the suite of AWS Cloud Resilience services like AWS Resilience Hub, AWS Fault Injection Service (FIS), Amazon Application Recovery Controller, AWS Backup and AWS Elastic Disaster Recovery (DRS).
We explored the difference between zonal, regional and global services, the importance of control planes versus data planes in recovery paths, and included a case study on how AWS Lambda handles resilience under the hood. We wrapped up with the shared responsibility model and the concept of continuous resilience.
I really enjoyed co-presenting with Adrian, it was great to share the stage, we had a lot of fun putting the session together and delivering it at both events.
