Cloud technology is getting more recognition as more and more businesses have identified its benefits. Businesses are using a private cloud for intensive calculations, complicated computation tasks and larger storage capacity. Cloud computing is secure yet easy to access for employees and customers. Open Stack is the newest bird in cloud computing which open-source software is allowing everyone to build their private cloud systems.
What is Open Stack?
Open Stack is the combination of several software components that work with each other to create a complete cloud infrastructure. There are basically ten services of current version of Open Stack:
- Nova is the fabric controller of cloud computing and it exposes IaaS (Infrastructure as a Service). It also takes care of scheduling, provisioning, deploying and management of virtual machines.
- Swift is the highly distributed object storage service which allows the users to store data in a reliable way.
- Cinder is the block storage service which manages persistent virtualised storage devices of virtual machines created by Nova.
- Neutron deals with Networking as a Service of other Open Stack services. It also manages different elements of the network to provide secure network connectivity.
- Horizon provides the users with a unified GUI to manage all Open Stack services.
- Keystone is the identity service which manages user authentication and authorisation.
- Glance is the Image Storage service which manages registration and retrieving images from virtual machine.
- Ceilometer is the telemetry service which provides a framework for metering the resource usage of Open Stack cloud.
- Heat is an Orchestration service which implements the orchestration to allow the users to launch complex virtualised infrastructure.
- Trove provides Database as Service (DaaS) functionality to users and also takes care of provisioning, configuring and managing the database engines.
The modular architecture of OpenStack training in Jaipur makes it easy for administrators to manage different functionalities at a time. It also increases the overall uptime as an individual service can be updated independently while remaining services are running.
