What’s new in the Elastic Stack 8

A presentation at Elastic Meetup by Alexander Reelsen

What’s new in the Elastic Stack? 8.x edition & AMA Philipp Krenn | @xeraa Alexander Reelsen | @spinscale

Late 7.x Observability: Google Cloud Logs Integration, User Experience & Synthetic Monitoring Enterprise Search: Kibana Integration, Crawler Security: Osquery integration Stack: Runtime fields & Searchable Snapshots

8.x Observability: CI/CD, AWS Lambda visibility Enterprise Search: SharePoint Connector Stack: Security on by default, ANN & NLP, Field usage & Disk usage APIs, Lucene 9 Geo: Hex tiles, Vector tiles ARM support

Observability CI/CD

Security-on-by-default Whole stack! TLS Authorization + Authentication Running with Testcontainers

The Elastic Stack release for 8.0 happened a few weeks ago, and we’re already moving with big steps towards 8.2 already. We will cover interesting new features like vector search, NLP integration, performance improvements for queries and aggregations, along with the many new integrations in Observability and Enterprise Search.
