You’ll learn about:
How private and public keys pair to verify your identity
The role of biometrics and device-level security
How companies like Apple and Google are synchronizing passkeys
Current limitations and the future of interoperability
If you’ve wondered what makes passkeys different, how to set them up, and when they’ll finally replace passwords, this episode is for you.

Sonic OS Unlocked: The Future of Open Networking in the Cloud

Ever wondered how hyperscale data centers like Microsoft’s run their networks with unmatched flexibility and control? Meet Sonic (Software for Open Networking in the Cloud)—the open-source network operating system (NOS) that’s revolutionizing modern networking by breaking free from vendor lock-in and monolithic systems.In this deep-dive breakdown, we explore:✅ Why Sonic? – Born from Microsoft’s need to manage global-scale data centers, now an Open Compute Project (OCP) standard.✅ The Architecture – How containerization (Docker) isolates network functions (BGP, LLDP, SNMP) for fault tolerance and modularity.✅ The Brain: Redis DB – The single source of truth synchronizing config, app, and state databases in real-time.✅ Hardware Abstraction (SAI & SyncD) – How Sonic decouples software from hardware, letting you run the same OS on different ASICs without rewriting code.✅ Automation-First Design – Why CLI is for troubleshooting, but JSON/config files rule provisioning at scale.✅ Customizing the ASIC Pipeline – How P4 profiles let you tune hardware resources (L2/L3 tables, VXLAN, MPLS) for leaf/spine roles.Whether you’re a network engineer transitioning from traditional NOS or a cloud architect deploying hyperscale networks, this video gives you the conceptual blueprint of Sonic—without drowning in CLI commands.🔗 Dive into the docs: Open Compute Project – SONiC💡 Next Steps: Explore pipeline resource management and SAI deep dives to master Sonic’s full potential.
