FOSS Singapore X Grafana & Friends Year end Meetup

We are pleased to organize our year-end meetup in collaboration with Free and Open Source Singapore on December 11, 2024.

AGENDA:

1. Welcome by Organizers and Venue Host
2. Presentation by Thijs Feryn from Varnish
Synopsis: We use caching proxies like Varnish to accelerate our web content and to make our platforms more scalable.
However, ensuring the right content is removed from the cache at the right time is equally important. Some may argue that the impact of caching too long is way bigger than not caching long enough.
Imagine a new website that cannot show a breaking news story on its website, because the cache still contains the old version.
In this presentation, we’ll take a closer look at how cache invalidation, cache revalidation and cache purging works.
Here are some of the main topics we’ll cover:
- How to identify and categorize content in the cache
- How to identify outdated content
- How to remove one or more objects from the cache
- How to control the blast radius of cache purges
- How to mitigate the performance impact of purged objects from the cache
- The difference between purging, invalidation & revalidation
- How to implement a cache invalidation strategy in your application
- How to secure access to your cache invalidation endpoint
3. Presentation by Joe Blubaugh from Grafana
Don’t Get Out of Bed for Anything less than an SLO
Service level objectives are a powerful monitoring and alerting philosophy that can reduce stress for on-call engineers and keep teams focused on delivering value to customers.
We’ll cover:

• The concept of “service level.”
• Measuring service levels effectively
• “Error budget” and realistic objectives
• Multi-window, multi-burn rate alerting rules.
• OSS tools that can help you get started with SLOs

4. Networking
We look forward to seeing you all and welcome you to join us at this event.

We are also looking for a host for the Grafana & Friends Singapore community, so reach out to us if you wish to participate.

See you at the event :)
