Keynotes - CNCF Project Update
Cloud Native Computing Foundation15
Rook: Sandbox -> Incubation
CN Orchestrator for distributed storage systems
● v0.7 released Feb 21, v0.8 released July 18
○ 545 commits total
● Instituted formalized project governance policies, added a new maintainer
● Rook Framework for Storage Providers
○ Makes Rook a general cloud-native storage orchestrator
○ Supports multiple new storage solutions with reusable specs, logic, policies
○ CockroachDB and Minio orchestration released in v0.8
○ NFS, Cassandra, Nexenta, Alluxio ongoing
● Ceph support graduated to Beta maturity
● Automatic horizontal scaling by the Ceph operator
● Improved security model and support for OpenShift
● Numerous other features and improvements
Progress Since Sandbox Entry
17
Adopters: Production Usage
18
There are additional adopters of Rook, especially those with on-premise deployments, that are
not ready to share the details of their usage publicly at this time.
Centre of Excellence in Next
Generation Networks
19
● 20 bare-metal nodes providing 100TB, with more being added
● Heterogeneous mix of nodes with high disk density as well as
compute-focused nodes
● Several databases, web applications, and a self-hosted file sharing
solution
“Rook is giving us a big head start in deploying cloud-native Ceph...having an
operator that can help deploy and manage Ceph in a cloud-native environment
is an ideal solution...gives us the ability to leverage both the storage and the extra
compute capabilities of the storage-dense nodes”
Raymond Maika, Cloud Infrastructure Engineer at CENGN
Cloud Native Computing Foundation20
Cortex
Horizontally Scalable, Multi-tenant Prometheus
What is Cortex?
Horizontally Scalable, Multi-tenant Prometheus
● SaaS monitoring system, compatible with Prometheus
○ On-Demand “Prometheus instances”
○ Provides complete Prometheus monitoring system that is API and PromQL compatible
● HA, Horizontally scalable, Long-term storage
● Multitenant
○ One cohesive system, not pod-per-client
○ Tenancy encoded throughout the architecture and into the data storage layer
● Cortex is Cloud Native
○ Microservices-oriented architecture
○ DHT-based ingestion tier and stateless query tier
○ Deployed with Kubernetes; delegates orchestration of components to K8s
○ Backed by NOSQL storage - DynamoDB, Bigtable, Cassandra
Adopters End Users
~1 million samples/s
~60 million timeseries
Alternatives
● Prometheus + InfluxDB
○ From InfluxData
● Prometheus + Thanos
○ From Improbable
○ Long-term storage, global query view
● Timbala
○ By Matt Bostock
○ Replication, global query view
● M3DB
○ From Uber
○ Automatic scaling
Cloud Native Buildpacks
© 2018 Cloud Native Computing Foundation26
Buildpacks
An opinionated solution for building apps from source code, primarily used on Heroku and
Cloud Foundry (by Pivotal, IBM, SAP, SUSE, GE, 18F & others). Also available on Gitlab,
Knative, Deis, Dokku, and Drie.
Values
• Designed for App Developers
• Source Centric
• App Aware
• Composable
• Operator-friendly
What it can do
• Produce OCI images that can be managed by Helm, stored in
Harbor, and deployed to Kubernetes
TiKV
An Open-Source Distributed Transactional Key-Value
Store
An open-source distributed transactional key-value database
● Scheduling and Auto-Balancing
● Multi-Raft
● Dynamic Range-based Partition
○ Split / Merge / Leader transfer (how we resolve hot spots)
● ACID Transaction
○ 2-Phase Commit with Optimistic Lock
● Written in Rust (No GC stoptime / No runtime cost)
● Inspired by Google Spanner and compliment Vitess
