This document provides an introduction to cloud-native platforms and Kubernetes, and demonstrates how Redis Enterprise can run on these platforms. It discusses how Kubernetes provides orchestration of containers and manages the application lifecycle. It then demonstrates deploying Redis Enterprise on Kubernetes, showing how it uses a custom Kubernetes controller and operator to provide auto-bootstrapping of Redis clusters within Kubernetes pods. The demo shows creating a Redis database, service discovery, and benchmarking tool deployment on the Kubernetes-hosted Redis Enterprise clusters.

2. Agenda
• Introduction to Cloud-Native Platforms
• Introduction to Redis Enterprise
• Kubernetes Release Demo
• Q & A

3. Introduction to Cloud-Native Platforms (PaaS)
• Cloud Models: IaaS, PaaS, SaaS
• Why PaaS?
• Provide a higher level of abstraction
• Application developer can focus on application development
• Encourage micro services deployments
• Containers are now basic unit of deployment

4. Why you need Orchestration!
• Containerized workloads demand choreography
• Microservices adoption increases operational overhead
• with dozens of discrete components
• Orchestration Platforms
• Cloud Foundry - Build and Run containerized cloud-native applications
• Kubernetes – Run containerized cloud-native applications

5. Introduction to Cloud Foundry
• Application PaaS
• You provide
• Application code
• Platform provides
• Application runtime – Buildpacks
• Containerize & schedule your application – Diego
• Networking & Routing – GoRouters
• Logging – Loggregator system
• IaaS Orchestrator – BOSH
• Open Service Broker – OSB-API
• Use-Case
• Micro service applications
• runC compatible containers
• 12 factor applications

6. Introduction to Kubernetes
• Why Kubernetes?
• Orchestration of containers – Containers as a Service (CaaS)
• Application Life Cycle management
• It provides basic health checks for containers
• Does rolling updates
• Has a very declarative definition
• Provides Service discovery
• Use-Case
• Greater flexibility & customization of containerized applications

7. Introduction to Redis Enterprise
Open source. The leading in-memory database platform,
supporting any high performance operational, analytics or
hybrid use case.
The open source home and commercial provider of Redis
Enterprise (Redise) technology, platform, products & services.

10. Redis Enterprise on Cloud Foundry
• Design Goals
• Shared Multi-tenant cluster
• Orchestrated by BOSH
• Leverage TCP routing
• Multi foundation database replication
• (CRDTs)
• Deployment models
• PCF integrated Tile
• PCF Service-Broker Tile

11. Redis Enterprise on Kubernetes
• Design goals
• Built for Container Era
• Auto bootstrapping of cluster
• Leverage Persistence
• Architecture

12. Cluster of Clusters: Deep-Dive
• Cluster within a Cluster
• Kubernetes cluster
• Nodes, Pods
• Custom K8s Controller
• K8s scheduler
• K8s auto-healing
• Redis Enterprise Cluster
• CNM – Cluster Node Manager - runs on each node
• DMC Proxy – Smart Proxy – Provides extended Redis functions (Sharding, Clustering)
• Cluster Watchdog – Determines the current Redis Master Node
• Node Watchdog – Initiate Redis/listener failover as required.
• CCS – Cluster Configuration Store – Contains configuration for entire cluster (on each
node)

13. Why Orchestrator2
• K8s Controller and Operator
• Leverage K8s primitives and guarantees
• Use Redis Enterprise Orchestrator
• DMC Proxy – fast & transparent proxy
• Redis Enterprise scheduler to schedule shards to specific cluster nodes
• Use various deployment models – Symmetric nodes
• VPC
• Cloud
• Software

14. Live Demo?!

15. Demo – Recap
• Show deployed Pods, Service, Deployment, StatefulSet
• Show database creation
• Show service discovery
• Show benchmark tool deployment
• Delete Redis Enterprise database and service endpoint
