Cloud Computing
The delivery of on-demand computing services is known as cloud computing. This type of service allows users to access applications, storage, and processing power over the internet without needing to own or maintain any infrastructure or data centers. It is a convenient, pay-as-you-go service that users can rent, affording them the advantages of utilizing computing technology without the complexity of owning and maintaining it.
Cloud computing services providers also benefit greatly from economies of scale by providing the same services to a large number of customers. This allows them to reduce operational costs, while still providing a quality service. By utilizing cloud computing, both users and providers can reap the benefits of the technology without the burden of owning and managing computing infrastructure.
Fog Computing
Fog computing is a decentralized computing infrastructure or process in which computing resources are located between the data source and the cloud or any other data center. It is a paradigm that delivers services to user requests from edge networks. At the fog layer, devices such as routers, gateways, bridges, and hubs are utilized to perform both networking and computational operations. In comparison to cloud servers, these fog devices are resource-constrained; however, their decentralized nature and geographic spread offers extensive coverage and a more dependable service. Fog computing utilizes devices that are much closer to users than cloud servers, thus giving it its physical location.
Difference
Below is a comparison of Cloud Computing and Fog Computing:
Cloud computing
• Fog computing has lower latency than cloud computing.
• The system has a fast response time.
• Fog Computing offers more security than Cloud Computing.
• the speed of access is contingent upon the connection of the virtual machine.
• Multiple data sources can be combined.
• Mobility in cloud computing is restricted.
• Cloud computing provides partial support for certain applications and services.
• Cloud computing has a limited number of server nodes.
• Services accessible via the internet.
• A data center building equipped with air conditioning systems.
• IP network
• A robust network infrastructure is essential.
