6 Feature Velocity Essential for Cloud Cloud-scale creates the following requirements on switch firmware: Disaggregate firmware features Minimize the baggage switch firmware loaded with only features needed Operators can select the best building blocks for the job Hitless upgrade so updates don t cause customer impact Fix bugs or apply security patches in hours Rollout features in days Development environment Realistic emulation environment

7 SONiC Containerized

8 SONiC Containerization Container Strength Clean isolation Easy deployment Transactional Run universal SONiC Benefits Serviceability Extensibility Development agility Cross-platform What Would Containerized SONiC Enable?

9 SONiC Containers Peek into Arista ceos

10 SONiC-P4 Software Switch

11 SONiC Container Orchestration with Swarm Joint work with Docker Manage a cluster of SONiC switches with Swarm. Simple architecture with very few components Easy to use single command to create cluster Declarative service model Powerful rolling update and rollback

16 Object Library w/ Redis Backend SONiC Architecture - Switch State Service (SWSS) DB: persist objects App DB: persist App objects DB backend: redis with object library SyncD: sync objects between software and hardware Orchestration Agent: translation between apps and objects, resolution of dependency and conflict Network Applications Orchestration Agent APP DB DB Key Goal: Evolve components independently Enable easy integration of containers Enable large scale debugging SyncD ASIC

17 Other Capabilities in SONiC Diagnose based on Switch State data Steaming data out from Redis DB for monitoring ASIC level diagnostic capability Adding TAM, critical resourcing monitoring, microburst monitoring, INT etc Scenarios driven by cloud scale troubleshooting requirement

18 Docker Orchestration with Swarm Simple Simple architecture. It has very few components running in manager or worker nodes. Easy to use. Create cluster in single command. Almost no need to read manual for Docker users. Declarative service model Extend Docker API to cover service, node, secret primitives. Built-in raft store to persist system state. Secure by default Built-in CA to support cryptographic node identity and key rotation. Encrypted network communication. Powerful Support service rolling update / rollback Built-in routing mesh to implement load balancing Flexible and platform independent. Easy to integrate into existing infrastructure.
