Openstack Tutorial for Beginners: An Introduction to Cloud Computing and OpenStack

The open fact project is an open source cloud computing platform. that supports all types of the cloud environment. the project aims for simple implementation massive scalability and a rich set of features. cloud computing experts from around the world contribute to the project. 
OpenStack to widen infrastructure-as-a-service solution through a variety of complemental services each. service offers an application programming interface or API. that facilitate this integration. here is a conceptual architecture of OpenStack which shows the component services which make up OpenStack plaza. the identity service is codenamed keystone and it provides user management. 
the computer service called Nova provide the virtual machine management. and the image Service codename plans manages virtual images like Colonel, abilities are disconnected. the web dashboard for name horizon provides great console via the web browser. the object storage service is also known as Swift provides cloud storage locker storage service is known offender
provides storage management for virtual machines. Network Service codename neutron provides virtual networking management orchestration service. Also known as heat provide orchestration function for virtual machines. And meeting service called millimeter provide the function of users management for accounting. 
And here is the same list of services in a tabular format. let's go over them one by one horizon is a dashboard a guy based. friend for the user the user can just log into the horizon and navigate the green to face and consume all the cloud services. For example virtual machines storage etc there are also some other ways the user can access these components. but the main user interface dashboard the horizon know what it is a hypervisor level component. no one to work gives him then which is the hypervisor responsible for creating the Vian's. 
Neutron is a service which provides a network to the virtual machines it provides services like routing DNS DHCP and another network services. Swift provides object storage as a service. something like Dropbox with services like Dropbox Google Drive we can directly copy view and share files with them and we can also access this cloud drive anywhere. we actually don't need any system attached to them like. 
an external drive we can basically just open our browser and access these files. so similar functionality is provided by Swift. Center provides block storage Another service. it is more like attacking a hard disk the machine so we can just create volumes and attach them to know what computer services. and we can create the partitions and stored media then east on Keystone is a service which provides authentication and authorization. 
Basically, all the services communicate amongst them with the help of keystone. it enables role-based access control and provide granularly access level two different users and products, for example, a user is provided with the token and catalog by keystone after logging in which he or she will be able to use to access other services. glance provides an image as a service. 
we can upload images like you want to read that right into glance. so when we try to launch a VM in nova it just picks up the image from Class. next we have millimeter which provides metering and alarming services. the next to services are heat which provides an efficient service. and crop which provides a scalable and reliable cloud database for OpenStack services.
