Compute schedules virtual machines to run on a set of nodes by defining drivers that interact with underlying virtualization mechanisms, and by exposing the functionality to the other OpenStack components. Additional comments and reviews: Maya Shiran and Xiao Gao In this blog post I will talk about the automation and orchestration of configuration that can be done via the Heat automation and orchestration program that comes with OpenStack (and VIO- VMware Integrated OpenStack). Compute schedules virtual machines to run on a set of nodes by defining drivers that interact with underlying virtualization mechanisms, and by exposing the functionality to the other OpenStack components. Component. Heat is the orchestration component of OpenStack, which allows developers to store the requirements of a cloud application in a file that defines what resources are necessary for that application. The OpenStack logical architecture. In this way, it helps to manage the infrastructure needed for a cloud service to run. OpenStack is broken up into services to allow you to plug and play components depending on your needs. Test your knowledge of these core OpenStack components The OpenStack platform contains a mix of services for compute, networking, security and more. OpenStack Compute serves as the core of the OpenStack cloud by providing virtual machines on demand. OpenStack Image Service (glance) Heat. This is a query API compatible with AWS CloudFormation. TOSCA – Heat ideas and standards. Orchestration hinges on API. OpenStack Orchestration. For this section, we are going to talk about the OpenStack community components as part of its core. In the previous articles, I gave you a gentle introduction to Heat, and then I showed you some techniques to orchestrate the deployment of single and multiple instance applications on the cloud, all done with generic and reusable components. OpenStack node types. OpenStack is a very big platform that has many small components, assuring the full functionality of its services. This is the fourth and last article in my series on OpenStack orchestration with Heat. Originally introduced as Quantum in September 2012, it was renamed Neutron a year later to avoid confusion with a data storage vendor with the same name. This is an OpenStack-native REST API that processes API requests using RPC to the heat-engine. It is responsible for launching new services and instances according to the given templates. Compared to OpenStack's other services, Neutron is a relatively recent addition. This blog post was created by Anil Gupta. Components of OpenStack. The mission of the OpenStack Orchestration program is to create a human- and machine-accessible service for managing the entire lifecycle of infrastructure and applications within OpenStack clouds. I wrote about these features in a previous post. See if you can identify which service performs which function with this quick quiz. The openstack map gives you an “at a glance” view of the openstack landscape to see where those services fit and how they can work together. Perhaps, a question on your […] heat-api. The OpenStack Landscape. OpenStack is a free open standard cloud computing platform, mostly deployed as infrastructure-as-a-service (IaaS) in both public and private clouds where virtual servers and other resources are made available to users. The heat-engine is the core component of the Orchestration service for OpenStack. An orchestration component which is responsible for automatic application installation & deployment including dependencies and relationships between components, KPI monitoring, analytics and feedback actions like auto-scaling and self-healing. Heat is the main project in the OpenStack Orchestration program. OpenStack Compute serves as the core of the OpenStack cloud by providing virtual machines on demand. There is a command-line interface that interacts with the Heat API and runs Orchestration commands using the AWS CloudFormation API. Most of those components are made by the open source community to help meet the needs of its users. heat-api-cfn. Component.
