Advantages and Disadvantages of Cloud Computing

Cloud computing is a kind of Internet-based computing that offers shared computer processing resources and data to computers and additional devices on demand. It is a model for allowing pervasive, on-demand access to a common pool of configurable computing resources (e.g., computer networks, servers, storage and services),which can be quickly provisioned and released with negligible management effort. Cloud computing and storage solutions offers users and enterprises with different capabilities to store and process their data in the data centres that might be located far from the user across the world. Cloud computing trusts on sharing of resources to attain coherence and economy of scale over an electricity network.
Cloud computing is the consequence of the evolution and adoption of present technologies and models. The goal of cloud computing is to permit users to obtain benefit from all of these technologies, without the requirement for deep knowledge about or skill with each one of them. The cloud targets to cut costs, and assist the users focus on their main business instead of being obstructed by IT obstacles. The chief allowing technology for cloud computing is virtualization. Virtualization software splits a physical computing device into several “virtual” devices, each of which can be simply used and managed to perform computing responsibilities. With operating system–level virtualization basically creating a scalable system of various independent computing devices, idle computing resources can be owed and used more competently.

Characteristics of Cloud Computing:

Agility for organizations may be enhanced, as cloud computing may rises users’ flexibility with re-provisioning, adding, or growing technological infrastructure resources. Cost decreases are claimed by cloud providers. A public-cloud delivery model adapts capital expenditures to operational expenditure. Device and location independence allow users to access systems by utilising a web browser irrespective of their location or what device they use. As infrastructure is off-site and opened via the Internet, users can connect to it from any place. Maintenance of cloud computing applications is simpler, because they do not require to be installed on each user’s computer and can be availed from different places. Performance is supervised by IT experts from the service provide, and reliable and loosely coupled architectures are made using web services as the system interface. Reliability advances with the use of multiple redundant sites, which creates well-designed cloud computing appropriate for business continuity.

Advantages:

Cost Savings

The most important cloud computing advantage is in terms of IT cost savings. Businesses irrespective what their type or size exist to receive money while keeping capital and operational expenditure to a minimum. Using cloud computing, one can save considerable capital costs with zero in-house server storage and application needs.

Reliability

Using a managed service platform, cloud computing is very consistent and constant than in-house IT infrastructure.

Manageability

Cloud computing offers improved and simplified IT management and maintenance abilities using central administration of resources, merchant managed infrastructure. IT infrastructure informs and maintenance is removed, as all resources are maintained from the service provider.

Disadvantages:

Security

Though cloud service providers apply the best security values and industry certifications, storing data and essential files on outside service providers always opens up risks. For example, in a multi-tenant cloud design where multiple users are hosted on the single server, a hacker may try to break into the data of different users hosted and kept on the same server.

Limited Control

As the cloud infrastructure is completely possessed, managed and monitored by the service provider, it converts nominal control over to the customer. The customer can just control and manage the applications, data and services functioned on top of that, not the backend infrastructure.

Vendor Lock-In

Though cloud service providers assure that the cloud will be flexible to usage and integrate, transferring cloud services hasn’t yet totally evolved. Administrations might find it tough to transfer their services from one vendor to another.
