March 2023: OpenTelemetry Metrics / Kotlin Server Side

This march event you don't want to miss, as we have 2 brilliant talks. Our very own Asaf Mesika (@StreamNative) will give you a primer guide on OpenTelemetry Metrics - the new metrics library aiming to conquer the JVM metrics frameworks space. Yair Galler (@Next Insurance) will give you Next Insurance retrospective on working with Kotlin for a few years.

Thanks to [Logz.io](https://logz.io/) for sponsoring the event!

Scaling Server Side Kotlin
A candid talk about of the experience of working with Kotlin at Next Insurance, scaling from a small startup to hundreds of developers.
I will survey what worked well and why it was worth it, as well as look at the pitfalls and what to avoid when working with the language.

Yair Galler
Yair is a hands-on architect at Next Insurance, helping to translate the complex world of insurance into reliable, elegant code. He also has a passion for developer productivity, constantly working on improving methods and tooling.

He previously led engineering teams at several early and mid-stage startups, tackling technological challenges ranging from Devops & backend systems to front end development.

OpenTelemetry Metrics: observability’s holy grail
OpenTelemetry Metrics is making a revolution both for microservices and libraries. I believe it is the most comprehensive metrics library ever written. This talk will guide us through understanding OTel as a whole, continue with OTel Metrics benefits, concepts, and entities in its API and SDK. Once done, you'll understand why it's so good, how it will benefit you, and why it will be the de facto metrics library. The examples will be in Java, but as you'll see, it's almost the same in any language.

Asaf Mesika
