RedisConf18 - Redis Cluster Provisioning with Kubernetes Service-Catalog Extension
Download as PPTX, PDF2 likes1,242 views
This document discusses Amadeus' use of Redis clusters with Kubernetes and their plans to offer Redis as a managed service. It introduces the Redis cluster operator which manages Kubernetes resources for Redis clusters. It then explains how the operator can be combined with an Open Service Broker to provision Redis clusters through the Kubernetes Service Catalog, allowing Redis to be offered as a managed service to applications in a simple way. A demo of this Redis as a service setup is planned.

Amadeus & Redis ● Young Redis user: 2 years (1 year in production) ● Use case: session management data storage ○ Enabler for cloud application deployment. ○ https://github.com/AmadeusITGroup/HttpSessionReplacer ● Runs Redis-Cluster in Openshift (Kubernetes) ○ In memory only ○ https://github.com/AmadeusITGroup/redis-operator 3
- 4. What is next? ● More applications using the service, multi cloud environments ● Internal Saas offer: Redis as a service ○ Dedicated support team ● Provisioning with: Open Service Broker API ○ Delivers service to application in a simple and elegant way. ○ Fujitsu, Google, IBM, Pivotal, Red Hat and SAP ○ Integration with Kubernetes Service-Catalog 4
