Kicking off our evening was Mikołaj Karebski from VirtusLab with his talk on Overcoming legacy manufacturing challenges with Google Cloud(starting at 8:58). His takeaways mention that:

  • The reality of a startup is developing a rough solution first, then refining it later.
  • Rushing into solutions can lead to wasted time and money.
  • Overcommunication ensures a faster information loop.

Next up we had Subomi Oluwalana from Convoy telling us about Webhooks & Webhook Gateways(starting at 43:26). He talked about how:

  • Webhooks are great and constitute a great API Design.
  • Traditional webhook gateways are often fragile and prone to failure under heavy loads. You’d need to design for resilience and fault tolerance carefully.
  • Traditional webhook gateways often fall short in terms of security measures. You’d need to safeguard against vulnerabilities such as Server-Side Request Forgery (SSRF), Replay Attacks, and DNS Rebinding attacks.

And wrapping up our evening was Richard Tweed discussing Using, and mis-using Kubernetes Dynamic Admission Control(starting at 1:29:54). His takeaways are about:

  • How Kubernetes Dynamic Admission Control can secure clusters.
  • How Kubernetes Dynamic Admission Control can take down a cluster.
  • How the new Validating Admission Policies will work.

Check out his slides - due to a technical issue, they were not available during the event.
