What is Cloud?
"The cloud" refers to servers that are accessed over the Internet, and the software and databases that run on those servers. Cloud servers are located in data centers all over the world. By using cloud computing, users and companies don't have to manage physical servers themselves or run software applications on their own machines. Cloud computing is the on-demand availability of computer system resources, especially data storage (cloud storage) and computing power, without direct active management by the user. The term is generally used to describe data centers available to many users over the Internet. Large clouds, predominant today, often have functions distributed over multiple locations from central servers. If the connection to the user is relatively close, it may be designated an edge server.
Types of Cloud
A Private Cloud is typically defined as everything behind a company's walls. These kinnds of systems operate in a company's local data centres, although some companies prefer to use colocated data centre facilities.
The Public cloud includes a whole host of services and companies. The most common names are AWS, Microsoft Azure and Hapih Host Cloud. However, you may also hear software as a service such as MS OFFICE 365, Included
A Hybrid Cloud deployment most typically describes a company is operating both a Private Cloud and Public Cloud. In Hybrid Cloud environment, The private and public services are integrated with one another.
A multi-cloud strategy is an approach that operates any combination of Priavte, Public and Hybrid Clouds. An organisation may have multiple Public and Private Clouds or multiple hybrid clouds all either connected together or not.
What is Public Cloud?
The term "public cloud" is used to differentiate between the original cloud model of services accessed over the Internet and the private cloud model. The public cloud is defined as computing services offered by third-party providers over the public Internet, making them available to anyone who wants to use or purchase them. They may be free or sold on-demand, allowing customers to pay only per usage for the CPU cycles, storage, or bandwidth they consume.
A public cloud is a pool of virtual resources—developed from hardware owned and managed by a third-party company—that is automatically provisioned and allocated among multiple clients through a self-service interface. It’s a straightforward way to scale out workloads that experience unexpected demand fluctuations. Unlike private clouds, public clouds can save companies from the expensive costs of having to purchase, manage and maintain on-premises hardware and application infrastructure - the cloud service provider is held responsible for all management and maintenance of the system. Public clouds can also be deployed faster than on-premises infrastructures and with an almost infinitely scalable platform. Every employee of a company can use the same application from any office or branch using their device of choice as long as they can access the Internet.
Public Cloud Security
Modern public cloud service providers take security very seriously. Providers employ specialized security staff to automate security functions and monitor the system for anomalies. Strict policies protect user data from being accessed by other cloud tenants. To gain access to additional levels of security, organizations can leverage a public cloud solution within a hybridized environment.
Why Use a Public Cloud?
A public cloud provides easy and fast scalability of computing, storage and other web-based resources. Servers can be deployed in minutes or hours, instead of days or weeks.
Users save money, as they don’t have to pay for data center costs like hardware, software, and IT staff. They also benefit from economies of scale, as the data center costs are shared among all users.
