What is the cloud?
‘Cloud’ refers to Internet-accessed servers, as well as software and databases that run on those servers. Since computing and storage occur on a server, not on the user’s devices, by using the cloud, users can use the same files and applications from virtually any device.
What is Cloud computing?
A cloud computing service is an on-demand access to computing resources over the Internet (“the cloud”), including applications, server hardware, networking, analytics, intelligence, database software, and development tools. The resources are provided by a cloud service provider (CSP), which runs the remote data center.
In this, you pay for only the cloud services you use, lowering operating costs, scaling infrastructure more efficiently, and reducing operating costs over time.
Types of Clouds
Public Cloud: With a public cloud, anyone can store and access information through the Internet by paying peruse. A Cloud Service Provider (CSP) manages and operates computing resources in a public cloud.
There are many public cloud providers, such as Amazon, Microsoft, and Google. Companies like these offer services as well as infrastructure that several customers share. Large amounts of space are typically available in public clouds, making them easily scalable.
Some advantages of public cloud include Lower Costs, Easy infrastructure management, Near-unlimited scalability, High reliability.
Examples of public clouds are Amazon Elastic Compute Cloud (EC2), Microsoft Azure, AWS, Google AppEngine, Sun Cloud, etc.
Private Cloud: Private clouds are also called internal clouds or corporate clouds. Organizations use it to build and manage their own or third-party data centers.
A private cloud is usually protected behind a firewall and used by one organization only. Like a public cloud, A private cloud can be accessed, utilized, and stored by authorized users from virtually anywhere. However, it is different because nobody else can utilize those computing resources.
Some advantages of Private Cloud include providing high security and privacy to users, better performance with good speed, More flexibility, More control, More scalability.
Clouds such as HP Data Centers, Microsoft, Elastra-private cloud, VMware, Hewlett Packard Enterprise (HPE), and Ubuntu are examples of private clouds.
Hybrid Cloud: Basically, hybrid clouds are a combination of public and private clouds. This technology allows the two platforms to work together seamlessly, while data and applications move seamlessly from one to the other. Businesses or organizations needing both options can use this solution based on their size and industry.
A hybrid cloud is partially secure since anyone can access the public cloud, while only those within the organization have access to the private cloud.
Examples of Hybrid Cloud are Google Application Suite, Amazon Web Services, AWS Outposts, Azure Stack, etc.
Community Cloud: A community cloud enables systems and services to be accessed by a group of several organizations to exchange information and applications. In essence, the community cloud is a private cloud that acts similarly to a public cloud.
An organization in the community, a third party, or a combination of organizations owns, manages, and operates it.
A community cloud is an attractive option for companies with stringent regulatory compliance requirements, such as healthcare, financial, and legal industries. In addition, they are an excellent choice for managing joint projects involving community-specific software applications or development platforms.
