ITC561 | Main Concepts Of Cloud Computing | Information Technology
Cloud computing is recognised as an extensive solution which offers information technology services. This web-based computing helps to offer shared resources as hosts in the cloud are configured to perform collectively. Hence, different applications make use of combined computing power such as it executes on a single system. The scalability of cloud computing is a characteristic of assigning on-demand resources. This helps in using cumulative resources of the system, negating the requirements for allocated particular hardware to a task.
Building blocks of cloud computing
Cloud computing model involves front end and back end. These essential components are linked via networks. Front-end act as a vehicle with the help of which users communicate with system and back end is cloud itself. Front-end comprises client computer, the computer network of an organisation and applications involved for accessing the cloud. The back end offers the computers, servers, applications along with data storage that generates the cloud of services.
The basic forms of cloud formations are mentioned as beneath:
- Public cloud: Public cloud can be accessed by the general public or wide industry group and is supervised by an enterprise selling services of the cloud. The resources in public cloud are dynamically provisioned across the web through web applications from off-site service providers that provide shares resources and then invoice by utility computing.
- Private cloud: Private cloud is available in the firewall of organisation and is managed by an enterprise only. These are a form of cloud services that are to be developed and managed in an organisation.
- Hybrid cloud: Hybrid cloud is an orchestration of private and public cloud using services present in both private and public space. The responsibilities of management are segmented among business and public cloud provider. With the help of hybrid cloud, an enterprise can identify the requirements and targets of services to be developed and receive them by appropriate
Importance of cloud migration
- Scalability: Scalability is very first benefits that are taken into account while interpreting the advantages of cloud-based The services based on the cloud are idyllic for enterprises having fluctuating demands it can customise the service. This elastic level of agility offers enterprises with pristine benefits over competitors ranking the operational agility as a top driver for adoption of cloud.
- Disaster recovery: It is essential for enterprises of almost any size to implement robust disaster recovery. However, due to lack of knowledge and capital, this is a crucial investment is kept at backseat till the occurrence of a disaster. Due to the emergence of cloud, enterprises came to the advantages of disaster recovery system. Cloud-based backup, as well as recovery, saves cost and time while preventing huge up front
- Higher collaboration: All the responsibilities and operations become complex to collate specifically in the enterprises that are growing at an alarming rate. A collective process is desired from a group to complete several tasks in the tightest time interval. This is the point where cloud system through its mobility and scalability provides great aid.
- Competitiveness: This is one of the crucial facets for the adoption of cloud. Because of a decrease in the bottom line for various organisations owing to cloud adoption, it reflects the expense of services offered to consumers. Cloud helps to decrease the cost of innovation.
- Security: Security violations like data theft, hacking and identity thefts often set enterprises back by crores due to exposure of confidential information in it. Cloud computing offers high security at occurrences.
- Mobility: Another setback that enterprises are plagued with is frequent business plans, as well as meetings to move from one state to others, happens regularly. Due to streamlined operations of cloud computing, one requires a connection of internet to avail data while working on The services of cloud provide mobile applications so that one is not restricted to the sole device to perform the work.
