Application M&O on OpenStack
2 likes609 views
This document discusses application management and operations (M&O) on OpenStack. It begins by noting that while OpenStack and other IaaS platforms address initial infrastructure needs, more is required to properly support existing and future applications. The rest of the document then summarizes various approaches for deploying and managing applications on OpenStack through tools like Puppet, Heat, Cloudify, BOSH, Murano and Magnum. It emphasizes the need for application M&O to be integrated with cloud and infrastructure M&O and to support cloud-native applications and microservices. The document promotes further research into tools like Magnum to provide container orchestration as first-class OpenStack resources.

- 19. 19 • BOSH is a project that unifies release engineering, deployment, and lifecycle management of small and large-scale cloud software. • It also performs monitoring, failure recovery, and software updates with zero-to-minimal downtime. • While BOSH was developed to deploy Cloud Foundry PaaS, it can also be used to deploy almost any other software (Hadoop, for instance). • In addition BOSH supports multiple Infrastructure as a Service (IaaS) providers like VMware vSphere, vCloud Director, Amazon Web Services EC2, and OpenStack.

- 21. 21 • Stemcell: A stemcell is a versioned Operating System image wrapped with IaaS specific packaging. • Release: A release is a versioned collection of configuration properties, configuration templates, start up scripts, source code, binary artifacts, and anything else required to build and deploy software in a reproducible way. • Deployment: A deployment is a collection of VMs, built from a stemcell, that has been populated with specific releases and disks that keep persistent data. These resources are created based on a manifest file in the IaaS and managed by the BOSH Director, a centralized management server. BOSH Major Concepts

Magnum uses Heat to orchestrate an OS image which contains Docker and K8s and runs that image in either virtual machines or bare metal in a cluster configuration. Future Research Plan - Magnum
