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.

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).
You might have heard the word “load balancing” several times but what do you think is that? The term defines the idea of dividing the work load equally among others when one person is unable to handle it. Similarly when we talk about web hosting it refers to distributing the load on single server to other server when a single server can’t handle it. When you click or type a web address you are routed through a host server to view the page. This means a load balancer spreads the “work” of running a website across multiple servers in order to ensure that the servers hosting the site aren’t overloaded.

Simply open your web browser, and type any website address in it. The browser will take you to the exact page or information that you are looking for. But, how does this happen? How could be browser so sure that the information on this server is what is needed by the user? The browser knows it because of the DNS – Domain Name System.
The fact is, when you enter your domain name in the browser, it sends a request to the DNS server which holds the lists of “domain-ip-addresses”. By searching the IP address of that particular domain, it forwards the request to the specific web server where the website data is stored and once it is found, it is resent to the browser, resulting the expected page or information the user is seeking for.
