What is Cloud Computing? (with examples)
Section I: The Cloud
What is Cloud Computing?
Cloud computing describes the storage of information or services via the Internet. This software will never save personal details on the computer. It is a service available to users on-demand for computers ranging from servers to databases and storage. Cloud computing focuses on providing data centre access to multiple users. User data may be accessed remotely.
Why is the Cloud called the Cloud?
Cloud computing was first developed during the 1960s. The expression originated from a cloud symbol used in flow charts to represent the internet.
How does Cloud Computing work?
Cloud computing enables a user to access data from a remote computer via the internet. The Internet network links a computer with a database that includes other databases, servers, and applications. The back end functions as an archive that stores information accessible from the front end. These communications between front and back ends are handled via central servers.
What are the advantages of Cloud computing over traditional hosting?
The advantages of using Cloud over traditional hosting are many. Here are some of them:
- Increased collaboration: With cloud services, it is easier for people to share and edit documents together. This feature is particularly useful for businesses where team members need to work on the same project from different locations.
- Cost savings: One of the biggest advantages of using cloud services is that it can help businesses save money. Cloud services are often priced on a pay-as-you-go basis, which means that businesses only need to pay for the resources they use.
- Scalability: Cloud services are highly scalable, which means that businesses can easily increase or decrease their use of resources as needed.
- Flexibility: Cloud services are also very flexible, which means that businesses can use them to support a variety of different workloads.
- Improved security: Another advantage of using cloud services is that they can help businesses improve their security posture. By storing data in the cloud, businesses can reduce their risk of data breaches and other security threats.
Types of Cloud Computing
There are three main types of cloud computing:
- Public cloud: A public cloud is a type of cloud computing that delivers services over the public internet.
- Private cloud: A private cloud is a type of cloud computing that delivers services over a private network.
- Hybrid cloud: A hybrid cloud is a type of cloud computing that delivers services over a public and private network.
Cloud Computing with example of use
The cloud has several uses including infrastructure as a service (IaaS), and Platform as a service (PaaS). In this way the company has the ability to control its own computer network or data without physically managing it.
Why do we need Cloud solutions?
The cloud gives businesses more flexibility than deploying locally based servers.
Cloud services provide the necessary bandwidth for a large network without the need to upgrade your system to meet a more demanding demand.
IaaS provides IT infrastructure to users via a website and has often been attributed to serverless computing.
Software and hardware for End User Services is delivered through PaaS and are usually provided by Software developers.
A software application can be created and run on the internet without a building or maintenance effort. SaaS software licenses are used in the context of subscription software enabling access via the internet using external servers without downloading or installing it locally.
What are some of the benefits of Cloud Computing?
Some benefits of cloud computing include
- Reduced costs: Cloud computing can help organisations save on the cost of purchasing and maintaining hardware and software infrastructure.
- Increased agility: Cloud computing can help organisations be more agile and responsive to changes in demand.
- Improved performance: Cloud computing can help improve the performance of applications by distributing traffic across multiple servers.
What are some of the challenges of Cloud Computing?
Some challenges of cloud computing include:
- Security: Organisations must ensure that their data is secure when using cloud-based services
- Privacy: Organisations must be aware of how their data is being used and shared by cloud service providers
- Interoperability: Organisations must ensure that their systems are compatible with the cloud services they are using.
What are some examples of Cloud Computing services?
Cloud computing services are those that provide a platform for users to access and use applications over the internet. These services are delivered through a web browser or a mobile app and are usually subscription-based.
Some examples of services utilising the Cloud include storage and file-sharing apps such as Google Drive, iCloud, Dropbox, and Microsoft Azure. There are also many streaming services for audio and video where media is retrieved from remote locations in a Cloud-based environment.
Is it safe to put your data in the Cloud?
Who is the most popular Cloud service provider?
The bulk of the world's Cloud infrastructure is held by just a few companies. The biggest being Amazon Web Services (AWS).
