The Basic Concepts of Cloud Computing Services
Cloud computing is more a paradigm, a model of delivery, a provision, and marketing of IT services rather than a technology per se, as some may believe it to be. It is a comprehensive solution that enables the delivery of IT as a service as opposed to conventional IT configurations, which were dominated by mainframe computing. It is computing based on the cloud—a distinct environment purposefully designed for remote provisioning of measured and scalable IT resources. It is an internet-based solution where resources are shared and distributed like electricity on an electrical grid. It is a flexible means to allocate resources on demand, facilitating the use of the system's collective resources without the need for a specific hardware to do a certain task. It is an amalgamated configuration that acts like an aggregated virtual computer and creates an environment where applications run and execute independently, regardless of the arrangement.
This paradigm shift has people and businesses rushing to get on-board because of its significant benefits, ranging from reduced costs, robust scalability, and refined personnel usage. Cloud computing not only reduces capital and operating expenses (resources can be acquired only when needed and paid for only when used), it also frees up the hands of your valued personnel, thus allowing them to focus on more important functions than maintaining software and hardware. Cloud computing also allows for true scalability, whether your business requires immediate expansion or reduction without the need for long-term commitment.
Cloud computing services can be grouped into three major categories, namely, infrastructure-as-a-service (IaaS), software-as-a-service (SaaS), and platform-as-a-service (PaaS). The infrastructure segment (IaaS) of the service provides processing environments. These include servers, firewalls, storage load balancers, and many more which can be implemented using different technologies. The most common form of delivery for processing environments is virtualization, although other configurations also exist such as clusters or grid technologies.
PaaS or platform-as-a-service provides the environment for developing as well as running applications. This also entails authorization, authentication, metadata, and session management. The most complex and advanced cloud model, SaaS or software-as-a-service enables functionalities that work to solve user problems. These include solutions that are designed for individuals or companies, ranging from business intelligence, to email systems, web conference, sales force automation, project management, and office automation suites.
There are also three different types of cloud formations that exist within the premise of cloud computing, including public clouds, private clouds, and hybrid clouds. Public clouds are accessible to the general public or a large industry group. They are owned and provisioned by a particular organization selling cloud services. Private clouds exist within an organization's firewall and are therefore managed by them. They are services that are created and controlled within the owner enterprise. Hybrid clouds, on the other hand, offer the best of both worlds where management responsibilities are shared between the business and the public cloud provider.
