This document summarizes a meetup about Kubernetes and cloud native technologies in Montreal. It announces upcoming presentations on CNCF and Kubernetes 1.12 updates, and securing container deployments. It also provides information about getting involved with local user groups, upcoming hands-on workshops from CloudOps, the Rook and Cortex projects joining CNCF, and TiKV key-value store.

Keynotes - CNCF Project Update

15. Cloud Native Computing Foundation15

16. Rook: Sandbox -> Incubation
CN Orchestrator for distributed storage systems

17. ● 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

18. 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.

19. 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

21. Cortex
Horizontally Scalable, Multi-tenant Prometheus

22. 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

23. Adopters End Users
~1 million samples/s
~60 million timeseries

24. 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

25. Cloud Native Buildpacks

26. © 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

27. TiKV
An Open-Source Distributed Transactional Key-Value
Store

28. 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
TiKV
