--------- The Talks ---------

Denis Jannot - The challenges of exposing and connecting microservices

In this presentation, Denis will cover the common challenges people are facing when they expose and connect micro services.

He will review the different options to expose services running on Kubernetes (Ingress vs API gateway) and to manage service to service communications (API gateway vs Service Mesh).

He will also discuss the additional complexity introduced when services are spread across multiple environments (multiple Kubernetes clusters, Service Meshes, ...).

Finally, Denis will introduce several Open Source projects (Gloo, Service Mesh Hub, Web Assembly, ...) which they are working on at Solo.io to tackle those challenges.


János Pásztor - Custom Autoscaling with Prometheus, Grafana, and a little bit of code

Some cloud providers give you the ability to automatically scale up or down based on simple metrics like CPU or memory usage. What happens if you need a complex logic? What if you need custom factors like combining CPU, RAM, and disk usage? Or application metrics?

Prometheus gives us a wonderful way to gather metrics from a varying number of machines using service discovery, and Grafana an easy to use way to create graphs and alerts. Let's combine these to build a custom, self contained and testable autoscaler for our cloud platform.


Meetup will be streamed on Youtube and Q&A will be done via discord.
