Understanding The Different Types Of Cloud Technologies
In today’s cloud computing world, there are some fundamental concepts that one needs to learn in order to get the full advantage of the various cloud technologies. Most users of the cloud computing world think that all the important aspects of cloud computing are similar to each other. However, when they actually start using the various cloud technologies they will realize that there are huge differences between the various cloud technologies.
Cloud technology is basically the on-demand provision of computing resource, mostly storage and data processing power, for use by an individual or small number of users. The term is normally used to refer to cloud servers available to a wide range of users across the World Wide Web. This type of cloud technology is called distributed cloud technology. The service providers provide the cloud computing software to the clients to make use of their cloud computing resources. The cloud consists of multiple data centers located at different places around the globe. Users access cloud services from anywhere with an internet connection. The most commonly used types of cloud services are virtual private servers (VPS) and dedicated servers.
On the other hand, dedicated servers are used to host a particular business application. The virtual private servers are more suitable for businesses that have a large scale of application needs. The dedicated server uses virtualization technology to isolate virtual machine resources from the physical machine resources. In other words, virtual machines are not hosted on a physical hardware, but on a virtual machine based on the same operating system. The most popular virtualization technology is VMware. Another popular virtualization technology is Xen.
As far as the cloud technology is concerned, one needs to understand that it is a dynamic technology. There are various types of cloud technologies such as Software-as-a-Service (SaaS), Content-based-Content-Centric (CBaaS), Application-centric-Content-Centric (ACCD), and Service-oriented architecture (SOA). In the case of SaaS, a business owner only needs to purchase and use the software, and pay the monthly subscription fees, while in the case of ACCD, business requires to buy the resources on the basis of usage and not on the basis of subscriptions. In SOA, the business owners have the freedom to choose the type of cloud and the content on which their resources are based.
Cloud technologies allow users to avail computing power from a single central location. But it must be ensured that the central location can be easily accessible. Therefore, the availability of a cloud service must be reliable, fast and reliable. This type of cloud technology is also referred to as infrastructure as well as it involves a lot of hardware, software and storage resources. In some cloud technologies, users can create, use and modify their own applications.
The availability of different types of cloud technology is also determined by the availability and the scalability of the underlying infrastructure and the availability of software and the infrastructure. Different cloud technologies come with different level of flexibility and scalability features.
