What is Cloud Computing?
Cloud computing is a virtual platform that provides services on-demand using the internet. The services include networking, software, databases, analytics, and storage. It allows you to access data from virtualized platforms. With the cloud, it is possible to expand to new geographic regions and deploy globally within a few minutes. When customers acquire cloud services, the provider satisfies those requests using advanced automation rather than manual provisioning or human interaction. There are three types of service models which include Software-as-a-service (SaaS), Platform-as-a-service (PaaS), and Infrastructure-as-a-service (IaaS).
What is Distributed Computing?
In Distributed computing, various autonomous devices connect to solve one single problem on numerous machines. They communicate over a network to do faster-computing activities than utilizing one computer. Distributed computer systems enable increased expansion to add software and computing capacity when business demands increase. The web application, or distributed applications and managing tasks such as a video editor on a client computer, task will be split into pieces.
What is the difference between Cloud Computing and Distributed Computing?
| Cloud Computing | Distributed Computing |
|---|---|
| Cloud computing is a virtual platform that provides services on-demand over the internet. | Distributed computing refers to solving a problem over distributed autonomous computers. |
| It is classified into four types: Public Cloud, Private Cloud, Community Cloud, and Hybrid Cloud. | It is classified into three types: Distributed Computing Systems, Distributed Information Systems, and Distributed Pervasive Systems. |
| The goal of cloud computing is to deliver services that have scalability, security, monitoring, and management. | The goal of distributive is to provide collaborative resource sharing by users. |
| Cloud computing provides hardware, software, and networking resources through the internet. | Distributed computing helps achieve computational tasks faster than a single computer as it takes a lot of time. |
| Some disadvantages of cloud computing are data loss or leakage, lack of control, fixed contract, Internet-dependent, etc. | A disadvantage of distributed computing is the failure of nodes; a slow network may create problems in communication. |
| Examples of cloud computing are Gmail, Facebook, DropBox, Big data analytics, Skype, and Whatsapp, which also require the cloud to store data. | The typical examples of distributed computing are Telecommunications networks (including cellular networks and the fabric of the internet), which operate over the web, handing off workloads to dozens of cloud-based virtual server instances. |
