Enhancing Kubernetes with Autoscaling & Hybrid Cloud IaaS SF Kubernetes Meetup, 17 Feb, 2016 Craig Peters, Dir of Product Management, Mirantis @peterscraig Bhasker Nallapothula, Principal Architect, Biarca


Why are we here?

Coders just wanna code

corollary

Infrastructure should be invisible Yet infrastructure is a requirement


OpenStack: open source infra API


Solution: Murano App Catalog Get, Share and Run Apps on Demand

Create Catalog ●  Easily add new apps ●  Describe forms, app

dependencies, suggested configurations, billing rules etc.

Deploy Apps ●  Deploy applications and

services with a push of a button

●  Choose apps, specify settings, and deploy

Automatically Manage Apps

●  Monitor with Ceilometer ●  Automatically self-heal, scale

up & down, failover, backup ●  Application specific actions ●  Track usage

Utilized by the OpenStack Community App Catalog

Hybrid Multi-Cloud Auto Scalable Infrastructure Application.

Goal : Demonstrate a Hybrid Multi-Cloud Auto Scalable Infrastructure, using Murano

app catalog based enhanced Kubernetes and OpenVPN applications.

Murano-deployable OpenVPN, Kubernetes applications from App catalog. Secure VPN connectivity between Private and Public cloud compute services.

Metrics driven approach to Auto (Elastic) Scale Up or Down of compute nodes in Hybrid cloud environment.
