Episode 54: Fusion Snapshots, with Lorenzo Fontana

In this episode, Phil Ewels sits down with Lorenzo Fontana, an engineer at Seqera with deep expertise in Linux kernel internals, eBPF, and systems programming.Full transcript and summary blog post here: https://seqera.io/podcasts/episode-54-fusion-snapshots/Lorenzo is the co-author of the O'Reilly book "Linux Observability with eBPF" and a key developer behind Fusion and Fusion Snapshots.We explore Lorenzo's fascinating journey from Linux security tools to bioinformatics infrastructure, and take a technical deep dive into how Fusion Snapshots actually work under the hood: including CRIU, incremental dumps, and how tasks can be frozen and migrated between cloud instances in under two minutes.🔗 Links mentioned in this episode:Fusion & Seqera:• Fusion Snapshots Blog Post: https://seqera.io/blog/fusion-snapshotting/• Try Fusion Snapshots with Seqera Compute: https://seqera.io/platform/Lorenzo's Background:• Linux Observability with BPF (O'Reilly): https://www.oreilly.com/library/view/linux-observability-with/9781492050193/• Falco Runtime Security: https://falco.org/Open Source Projects:• criu-static: https://github.com/seqeralabs/criu-static• staticreg: https://github.com/seqeralabs/staticreg• CRIU Project: https://criu.org/⏱️ Timestamps:00:00 Nextflow Podcast ep54: Lorenzo Fontana00:04 Welcome and intro01:33 Background in eBPF06:46 Becoming an expert in eBPF11:29 O'Reilly Book13:02 Falco and linux kernel bugs16:07 Move to Seqera20:42 Intro to Fusion26:18 Comparing Fusion to other solutions29:00 Fusion Snapshots31:15 How Fusion Snapshots moves tasks35:58 Contributions back to CRIU39:05 criu-static43:12 staticreg44:36 Fusion Snapshots broken down46:50 Fusion Snapshot spot reclamation50:18 Incremental dumps53:59 Fusion snapshot process timing57:25 Seqera full stack59:20 Call to action01:00:52 pigz01:03:41 How to try Fusion Snapshots01:04:42 AI usage in the future01:11:06 Wrap up📢 Connect with us:• Community forum: https://community.seqera.io• nf-core: https://nf-co.re• Seqera: https://seqera.io#Nextflow #Bioinformatics #CloudComputing #Seqera #FusionSnapshots #SpotInstances #eBPF #Linux
