The terminology of public cloud refers to an information technology architecture within which a provider manages computing resources and makes them available to different clients over the Internet. In simple words, a public cloud is a set of publicly available computing resources provided through virtual machines and software.
What is Public Cloud Computing?
Public cloud computing is a type of cloud computing that is provided by third-party cloud service providers over the Internet. They stand out for their high scalability, cost-effectiveness and flexibility. Therefore, various businesses and individuals are often interested in such services.
How Does Public Cloud Infrastructure Work?
By and large, cloud infrastructure is the various software and technologies that enable the delivery of cloud services to customers. Basically cloud infrastructure depends on server hardware, storage and networking equipment.
How Is the Public Cloud Structured?
The structure of the public cloud is highlighted by fault-tolerant technologies that are designed to ensure the security of customer information. Also, such systems are aimed at seamless disaster recovery, which is largely made possible by storing multiple copies of data in different locations.
Benefits and Challenges of Public Clouds
Let's break down the challenges and conveniences that today's businesses encounter while operating public clouds.
Benefits
The list of benefits of public clouds includes:
- Acceptable cost;
- Reduced time costs;
- Ability to transmit information anywhere in the world;
- Convenient and flexible customization;
- Flexibility for enterprises;
- Security and limitless scalability.
Challenges
Keep in mind that public clouds are not perfect and have a number of weaknesses. Among them are immediate security, occasional performance fluctuations, and not the most flexible customization.
Public Cloud Security
Modern cloud service providers are concerned about the security of their customers and take comprehensive measures to strengthen the infrastructure, such as hiring professional security staff and using up-to-date enterprise technical solutions.
Differences between public clouds, private clouds and hybrid clouds
There are 3 main types of clouds, namely hybrid cloud, public cloud and private cloud. Public cloud is considered to be the most popular among them as it offers an extensive range of variations for computing tasks. Private clouds are used for storing confidential information, they can, for example, store all the information of one organization. Hybrid, as the name suggests, combines public and private cloud, allowing the distribution of information depending on its confidentiality.
What makes a cloud public?
The conventional cloud is made available in compliance with 3 points, namely resource allocation, operation and management agreement.
What is cloud management?
The management of the cloud lies entirely on the provider's side, which deals with the issue of hardware maintenance, network support and software management for virtualization purposes.
Migration to the public cloud
As the name suggests, cloud migration is the process of moving digital business tasks to cloud storage. Looking at this process from a layman's perspective, it can be said that cloud migration is somewhat similar to moving. However, in this matter, the move only concerns information, IT processes and applications from one data center to another.
Conclusion
If a business wants to expand aggressively, the use of cloud computing is a must. These services offer organizations limitless scalability and flexibility, and many providers charge for the computational resources that are actually used by the organization. This billing form is named “pay-as-you-use” model.
