English [Auto] Indecision, let's learn about Oracle to see you are thinking what is see? Yes, the buzzword these days is cloud, right? Yes. Oracle came up with a new database called Oracle Wolesi, which supports the cloud computing. Now you are thinking, what is cloud computing? Right. So let's understand that cloud computing is an architecture where the services, such as the database applications development environment, the server infrastructure storage software, are available over the network and available for the users. Yes, they are all available on the network and organizations can pay money to use those services. All right, let's take an example. Suppose your organization want to process huge data and they don't have the necessary servers. So in order to do that, they have to buy all the servers, configure them, and then you have to analyze the data. Obviously, this takes time and money. So instead of that, you go to a cloud provider based on fee and use the servers for the task you need and walk out cool, right? Yes. You are paying a fee to the cloud service provider based on your usage and the provider is giving you the access to the servers in their cloud. The biggest benefit of this is it avoids you from buying new servers and employing people to configure those servers. OK, the same way how various server software application storage can be available on a cloud, even Oracle, once the database is designed to run on the cloud and be accessible as a service. Yes, this Oracle Dulcy database can be on a cloud and can be used as a service if required. You see here our Oracle database is in the cloud and it has various databases sitting within that Oracle database and several users are connecting to the cloud and then accessing the data, presenting the various databases. Maybe some of the users are accessing the data from The Hitcher database. Some are accessing the insurance database. Some are accessing the sales. Some are accessing the health care. Cool, right? Yes. That is why Oracle tagged Oracle toile software, which they see. OK, now you are thinking, how can Oracle database support this? Right. OK, to support this. Oracle came up with a container database. OK, think it as a massive database. OK, you have one big master database which we call it as container database. And within that we can install multiple databases which we may call as child databases. But in Oracle terminology, they are called pluggable databases. Yes, they're called as pluggable databases because you can plug them into the container database whenever you need. And if you want to move that pluggable database to some other container database, you can just unplug from this container database and move it to some other container database. It's so flexible, just like how you take a video player, plug it onto a TV, use it, and then take out the video player, go to a different TV and then plug it in. In the same way, you can take a pluggable database from one container database to the other container database. It's that flexible. OK, by coming up with this architecture, Oracle was able to provide Oracle to the database as a cloud service. Think about it in your organization. If you want to run something in a database, all you have to do is take your database and plug into the sea container database on the cloud and then you do all your work. Once your work is done, just unplug your database and move on. That's it. It's that simple. OK, that is why Oracle calls it as multi tenant who is a tenant. Dinant is a person who pays money for renting out a space right in the same way we can pay money to plug our database into Oracle clumsy container, use the satirises and then unplug it. OK, if needed, please revisit this video again so that you will understand why Oracle Troilo supports cloud computing. OK.
