What is the definition of cloud computing?

Cloud computing is the technology that relies on transferring computer processing and storage to the cloud. The concept of cloud computing revolves around facilitating the storage and processing of massive amounts of data through integrated operating systems at any time, using an internet-connected device and a browser.

Cloud computing is a means of accessing a shared pool of configurable computing resources that can be easily deployed and provided with minimal effort, without the need to interact with the service provider.


What are the benefits of cloud computing?

The question of why we use cloud computing is important, and the ideal answer can be found by reviewing the benefits of cloud computing, which include:

  • Cloud computing provides secure access to stored data and information, with proof of user ownership and the right to access and use this data.
  • It offers cost savings to users by eliminating the need for private devices, their purchase, and the associated maintenance costs.
  • The utilization of cloud computing can be controlled or reduced according to the user's needs.
  • Cloud computing is a distinctive way to protect information and data from loss or damage.
  • It has tremendous capability to run high-level applications and software on different devices, without requiring specific device efficiency, as it does not rely on the resources of the user's device but rather on the power of the network servers.
  • Cloud computing ensures continuous and consistent performance.


Cloud Computing Components

Dealing with cloud computing requires the availability of a set of elements and components, which include:

  1. Client or beneficiary: This is the individual or organization that receives the benefits and services of cloud computing by using their mobile phone or personal computer.

  2. Cloud infrastructure: It is the underlying infrastructure on which cloud services rely. It provides storage spaces for information, personal computers, and the Internet network.

  3. Applications: These are the applications that users run in the cloud, including software for word processing, spreadsheets, conferencing, information sharing, and collaboration with others.

  4. Platforms: These are entities that enable cloud computing to provide massive storage servers with high data processing speed, such as Apple and Google.

  5. Service: It is the service used by the cloud through the process of transforming computer products into services.


Types of Cloud Computing

Cloud computing is not limited to a single type; it encompasses various models. Let's learn about the types of cloud computing:

  1. Public Cloud: In cases where an organization deploys a public cloud model, all devices, software, and supporting infrastructure are owned and managed by the service provider. These services are exclusively provided over the Internet, and you can access and manage your computer through a web browser.

  2. Private Cloud: The private cloud model is dedicated to the cloud computing resources used within a single organization. The private cloud's location is determined within the on-site data center or can be hosted in the cloud by a service provider.

  3. Hybrid Cloud: Hybrid cloud computing combines private and public clouds to share applications and data. Hybrid clouds connect on-premises infrastructure and cloud-based resources, providing organizations with greater flexibility and deployment options.

It aims to address security challenges associated with different service models such as Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS).

  3. Security Responsibilities: While cloud service providers are responsible for securing the underlying infrastructure, customers also have a role in ensuring the security of their data and applications. This shared responsibility model varies depending on the cloud service model.

  4. Threats and Challenges: Cloud computing introduces unique security concerns such as data breaches, unauthorized access, insecure interfaces, data loss, and insider threats. These risks arise due to factors like multi-tenancy, shared resources, lack of physical control, and reliance on network connectivity.

  5. Security Measures: Cloud security employs a range of measures, including encryption, access controls, authentication mechanisms, intrusion detection systems, network security, and vulnerability management. It also involves implementing security best practices, complying with regulations, and establishing incident response and disaster recovery plans.

  6. Compliance and Governance: Cloud security addresses compliance requirements and industry regulations, ensuring that sensitive data is handled in accordance with legal and privacy standards.
