The main types of distributed computing are:
- Cluster computing
It involves connecting multiple computers (nodes) to work as a single system, sharing processing tasks and resources.
- Grid computing
Utilizes a network of geographically dispersed computers to work on a common task, often used for large-scale scientific or research projects.
- Parallel computing
It involves breaking down a large task into smaller subtasks that multiple processors can process simultaneously, optimizing computational speed.
- Peer-to-Peer computing
It enables individual computers (peers) to share resources and processing power directly, creating a decentralized network.
Examples of distributed computing include:
- SETI@home utilizes volunteers’ idle computer processing power to analyze radio signals from space in the search for extraterrestrial intelligence.
- Apache Hadoop is an open-source framework for distributed storage and processing large data sets, widely used in big data analytics.

- Google File System (GFS) enables distributed storage of large amounts of data across multiple servers.
What is cloud computing
Cloud computing is a paradigm that supplies online admission to a shared pool of computing assistance over the Web. It encompasses services like storage, processing power, and applications, allowing users to leverage computing capabilities without needing local infrastructure.
The benefits of cloud computing are:
- Cost efficiency
Users pay for resources on a pay-as-you-go basis, reducing upfront costs and allowing for more efficient budgeting.
- Managed services
Cloud providers handle maintenance and updates, relieving users of the burden of infrastructure management.
Cloud services offer seamless scalability, enabling users to increase or decrease resources based on demand.
Users can access services and data from anywhere with an internet connection, fostering remote collaboration and flexibility.
The main types of cloud computing are:
- Infrastructure as a Service (IaaS) provides virtualized computing resources over the Web, including storage, processing power, and networking.
- Platform as a Service (PaaS) allows users to develop, run, and manage applications without dealing with infrastructure complexities.
- Software as a Service (SaaS) delivers various software applications over the Internet, eliminating the necessity for local installations.
- Function as a Service (FaaS), or serverless computing, allows developers to execute individual processes in response to specific events without managing the underlying infrastructure.
Famous examples of cloud computing services include:
- Amazon Web Services (AWS)
It contains a comprehensive suite of cloud services, including computing power, storage, databases, machine learning, and more.
- Microsoft Azure
