Diagrams Of A Web Server With Api And Storage Created In Openstack

Controls hardware load balancers with plug-ins and the Networking API. If you increase OpenStack Object Storage, you must consider network bandwidth requirements. It is recommended to run OpenStack Object Storage on network connections with 10 GbE or higher. Object Storage Processes and archives logs from the web application servers.

Users can access OpenStack via the web-based user interface implemented by the Horizon Dashboard, via command-line clients and by issuing API requests through tools like browser plug-ins or curl. For applications, several SDKs are available. Ultimately, all these access methods issue REST API calls to the various OpenStack services.

The cloud controller runs the dashboard, the API services, the database MySQL, a message queue server RabbitMQ, the scheduler for choosing compute resources nova-scheduler, Identity services keystone, nova-consoleauth, Image services glance-api, glance-registry, services for console access of guests, and Block Storage services

The API server acts as the web services front end for the cloud controller. The compute controller provides compute server resources and usually also contains the Compute service. The object store is an optional component that provides storage services you can also use OpenStack Object Storage instead.

Identity API v2.0 extensions. API quick-start examples. With the TryStack OpenStack installation, these services work together in the background of the installation, and many of these examples work on TryStack.. After you authenticate through Identity, you can use the other OpenStack APIs to create and manage resources in your OpenStack cloud.

Enables users to submit API calls to OpenStack services through commands. As shown, end users can interact through the dashboard, CLIs, and APIs. All services authenticate through a common Identity Service, and individual services interact with each other through public APIs, except where privileged administrator commands are necessary.

use to install and instantiate an OpenStack web application environment using Wordpress as the sample application. These files are Heat templates that will create the virtual servers for each tier, networking, load balancing, and optionally, auto-scaling. Figure 1 Three-tier web application architecture overview

As a Cloud Administrator you can use a command-line or web-based dashboard provision, control, and automate OpenStack resources. OpenStack has an extensive API that is available to all cloud users. The following diagram provides a high-level overview of some OpenStack core services and their relationship with each other.
