Cloud characteristics and components

Last time we introduced a basic concept of cloud computing and what it is some common uses. Today we will be discussing some characteristics and components of cloud computing.

Singh and Veralakshmi (2012) have created a list of characteristics of cloud computing and are as follows:

1. Versatility
1. If cloud computing is going to be the way of the future, it will need to be versatile and flexible. Technology is constantly changing and if cloud computing is going to survive, it will need to change with the times.
2. Cost-effectiveness
1. Since cloud computing takes out the necessity of a physical space, resources can be saved on office space, furniture, etc. 
3. Virtualization
1. Moving more information to a virtual environment can help save space and reduce costs, by using less paper for instance.
4. Security
1. Security in the cloud does present a unique problem: with more sensitive information being stored in a virtual environment will increase the chances of the system being hacked. It will be important for information professionals using the cloud to keep abreast on all developments in cyber security.
5. Sustainability
1. As long as the cloud is compatible with current technologies, it will require very little maintenance over time and saving further resources that would have been spent on repairs.
6. Scalability
1. A major advantage of cloud computing is its ability to add features seamlessly. This feature will help further resources that would have been spent on improvements and upgrades.
7. User-friendly
1. At present cloud computing is fairly user-friendly, but again it will need to adapt with change to remain helpful. It is not clear how cloud computing will integrate with the consumer.
8. Resource Optimization
1. Cloud computing can help reduce costs in several ways, as has been demonstrated in the points above. 
9. Infrastructure and service-level agreements (SLAs)
1. Since the cloud resides in virtual environment, it can be access from virtually any computer and will certainly have an impact on mobile computing. However, with all the positive attributes of cloud computing, service-level agreements may present a new set of issues.

Components

Similar to characteristics, components of cloud computing describe possible applications, but ones that are closely related or unique to cloud computing.

1. Infrastructure: given the virtual environment of cloud computing, it is the hardware, rather than the software that is front and center. The infrastructure relies on other cloud compatible devices to share resources.
2. Storage: one of the most attractive features of cloud computing is its ability to store large amounts of data that can be accessed virtually anywhere, by anyone that has access to the network.
3. Platform: this segment, known as cloud platform, is a basis for managing software and hardware needs to run applications. Think of it as a web-based operating system.
4. Application: application software runs in the cloud and therefore eliminates the need to install, update and maintain software on the user's device. Another cost-efficient attribute of cloud computing.
5. Service: cloud service is a little more challenging concept. Essentially, it is an independent piece of software that can be used in tandem with other cloud services over a network.
6. Client: a cloud client, which can be hardware or software, attempts to use a cloud service over the network.

These are some of the uses and dimensions of cloud computing that are becoming more common. As future information professionals, it would be to our benefit and those we serve to learn about this innovative technology.
