Ubuntu Cloud Computing - Benefits of Ubuntu Private Clouds
As said earlier, Ubuntu cloud computing is powered and managed by Canonical Ltd. Any cloud computing package has three levels:
a) Infrastructure as a Service (IAAS);
b) Platform as a Service (PAAS); and
c) Software as a Service (SAAS)
When building a private cloud, the IAAS part is handled by Canonical Ltd. This level contains the hardware (servers, etc.), and system software such as operating systems. Most people prefer Intel for the Platform part. Intel has good resources that allow your engineers to build a flexible platform for software designers. Thus, you can have different cloud SAAS for different departments in your business. In Ubuntu private cloud computing, you are not restricted only to the storage part. You can upload your entire network to the Ubuntu cloud, thus making it more flexible and versatile.
One of the definitions of cloud computing says that a cloud should be able to adapt to different circumstances without requiring much efforts. It also says that the cloud should be able to handle smaller responsibilities on its own. These responsibilities include logging, allocating and freeing up space as and when required.
Using Intel resources, you can build such an integrated PAAS for your application and software designers. Once the platform is engaged, different departments can start working on deployment of different Software as a service (SAAS) that works for different departments. If you do not have the expertise required to build the PAAS, you can contact Ubuntu Support.
Advantages of Ubuntu Private Clouds: If anyone asks me what is best about Ubuntu private clouds, I would say the customer support. Ubuntu's customer support helps you with all possible aspects of cloud computing. This means if you do not have the expertise to build the PAAS, you can ask for help from Ubuntu Support anytime. Depending upon your requirements, they may send in consultants or engineers who will set up the platform for you.
Once the platform is set, the ball is in your hands. You need to figure out what departments need automated services and accordingly, engage your software and application developers to create Software as a Service for the identified departments.
By now, you may be having some questions of the following type: What would be the advantages of Ubuntu Private Cloud? Why not use a traditional client-server model? The answer is IAAS. You need not worry about the Infrastructure as it would be offered by Canonical and Ubuntu. You need not purchase it. You need not worry about the maintenance of the infrastructure. Backup servers are also normally covered in the IAAS part. All this is taken care of by Canonical and Ubuntu, whereby you save on money and time.
Advantage - Versatile Servers: In case your storage suddenly increases, you can increase the size of your private cloud by bursting into the public clouds. Later, when the storage needs decreased, you can leave the public cloud. If the increase of storage is a permanent need, the IAAS part will take care of it in real time so you need not worry. All you need is to give a call to the Ubuntu cloud computing customer support.
This explains Ubuntu cloud computing in short. If you need further explanations or if you have any doubts, please feel free to comment below and I will get back to you with answers.
