Characteristics of Cloud Computing

Cloud Computing:

Cloud computing could be of many types, as the cloud could be hybrid, public or personal. Since the beginning of Information Technology, it has performed a vital share in making certain that businesses and corporations work efficiently. It offers services that are consistent, accessible, and protected consistently. Cloud computing attracts end users and consumers due to its peculiar exceptional uniqueness.

Characteristics of Cloud Computing:

1. Scalability:

Fast scalability is the main feature of cloud computing. ‘Scalability’ means the number of sessions, consumers, operations and transactions which can be held by the entire system. In simple words, scalability means doing what a person does in a bigger way. A scalable platform permits businesses to deal with large-scale business issues via the high-performance processing of huge data volumes.

2. On-demand self-service:

A customer’s requirements can alter from time to time which is known as ‘on-demand‘. The important factor is that all the provisioning procedures don’t require human interference. On-demand self-service implies that the customers, comprising non-IT persons may unilaterally provision the service and scale it up or down by them. Cloud service suppliers offering on-demand self-services comprise Salesforce.com, Microsoft, Amazon Web Services (AWS), IBM, and Google, NASDAQ and New York Times are corporations that use AWS.

3. Broad network access:

Cloud applications and facilities are available over the network. It can be used using standard procedures which encourage use by various thick or thin customer platforms such as PDAs, laptops and mobile phones. Broad Network Access implies the service is uninterruptedly accessible by using the standard selection of tools comprising conventional mobile tools, PCs and portable computers.

4. Quick elasticity:

Cloud services may be flexibly and swiftly provisioned, in a few instances mechanically, to rapidly scale out and swiftly to rapidly scale in. The facilities accessible for provisioning to the customer frequently seem to be infinite and may be bought in any amount at any time. Imagine that you are hosting a website and you get 1000 hits per day on average.

All of a sudden, you’re deploying a project and for a specific day, lots of users will be logging in online at a similar time. At that particular instant, there may be 100000 hits in a day. For such a situation, during a usual day, the cloud will allocate you one server but in peak time, it will go up to seven servers and back to one server in the usual hour. The finest feature is that you simply pay as per the usage.

5. Calculated service:

Usage of cloud computing resources may be controlled and reported while providing transparency to both the customer and provider of the used service. Cloud computing services use a metering facility, which allows for optimizing and managing resource use. This means as for electricity, IT service are also charged for each usage metric, that is pay for every use. The more you consume, the more the bill.

6. Resource Pooling:

The computing resources of the supplier are grouped to cater to numerous customers using a multiple-renter module, along with distinct virtual and physical resources vigorously allocated and reallocated by the requirement. The resource includes memory, storage, processing network bandwidth, various mail services and virtual machines. The joint grouping of the resource makes scale economies. Resource grouping is regarded as forcefully conveying computing resources to numerous consumers. It may modify from time to time according to the needs of users.

7. Multi-persistence:

It refers to the desire for strategy-focused segmentation, enforcement, control, separation, invoicing modules and service levels for distinct customer areas. Customers could consume public cloud service offerings of suppliers or be from a similar company like discrete business entities instead of different management units, but would yet share infrastructure.
