Introduction to the Eleven Key Components of OpenStack – Part 2

Openstack_Part 2

Until now it might be quite clear what is OpenStack? You can simply say that OpenStack is stack of open source software that are used by the service providers to setup and run their cloud compute and storage infrastructure. In the previous post we engulfed the knowledge of OpenStack and its five key components out of eleven. In this post, we will continue with the next six components that contribute to OpenStack.


Dashboard (Horizon) –

It offers a web-based portal for interacting with all the underlying OpenStack services like NOVA, Neutron, etc. That means it is the primary graphic user interface for using OpenStack clouds. With this tool users and administrators can provide and automate services. Also, developers are able to access the OpenStack components individually through an application programming interface (API).

OpenStack Networking (Neutron) –

It is an API-driven system for managing networks that can be plugged as well as scaled. After network customization, it allows to spin up and down several variant network types (like flat networks, VLANs or virtual private networks) on-demand. Neutron permits dedicated or floating IP addresses. In addition, it is supportive to OpenFlow software defined networking protocol and services including load balancing, intrusion detection and firewalls with the help of plugins.

OpenStack Telemetry Service (Ceilometer) –

Monitoring the usage of cloud services and deciding the billing accordingly is the major role of Ceilometer. Additionally, it can be used for deciding the scalability and obtaining the usage stats.

Orchestration Heat –

An orchestration engine that enables developers in automating the deployment of infrastructure is known as heat. With orchestration heat, developers can store the cloud application requirements in a file defining the resources essential for that application. This permits for easier onboarding of new instances. Heat also comes with an auto-scaling feature with which additional resources can be added as required by the services.

Trove –

Designed to run entirely on OpenStack, Trove is a Database-as-Service for OpenStack. It allows users quick and easy utilization of relational or non-relational database features without the stress to handle complex administrative tasks. The prime objective of the service will be providing resource isolation at high performance parallel to automating complex administrative tasks including configuration, deployment, monitoring, backups, patching and restores.

Sahara –

OpenStack Sahara formerly known as Savanash was started by Red Hat, Mirantis and HortonWorks during the OpenStack Havana summit in Portland. It enables OpenStack software to control Hadoop clusters. It offers the foundation and innovation hub for clear infrastructure resources management.

With OpenStack cloud operating system, enterprises and service providers can offer on-demand computing resources by providing and managing large networks of virtual machines. Focused on delivering flexibility as per your cloud design, it’s capable of integrating with legacy systems and third party technologies. After getting introduced to the eleven key components of OpenStack, it would be easier for you to gain deep knowledge of OpenStack.
