With the development of technologies which resulted in the emergence of the Internet of Things, companies worldwide started implementing cloud computing solutions as an alternative to on-premise software. With information getting to a cloud, it became much easier for businesses who deal with customer data to collect, access, analyze, and further use it. Furthermore, cloud solutions allowed to store all the data received from crucial sources of information in one place, freeing businesses from headaches associated with spending money on memory storage capacity or on expending computing power.
But despite all the benefits cloud computing brings the technology is not standstill. The requirement for reduced downtime contributed to the emergence of new kinds of cloud computing that perfectly solve this problem. Today, these solutions are known as fog computing and edge computing.
This article aims at showing the main difference between cloud, fog, and edge computing, allowing you to answer the question on which one is better for your needs. But to start with, let’s disclose the reasons for the emergence of edge and fog computing.
Why Businesses Need Alternatives to Cloud Solutions?
Cloud solutions indeed help businesses in reducing the cost of data storage. Nevertheless, this does not mean that it costs nothing: the more you store, the higher is the price. That is why questions on whether it is necessary to store everything in the cloud and is there a way to separate and then select data that will go to the cloud storage appeared.
As soon as companies are receiving data from a range of sources, it became evident that some part of the data received is less useful, and could be stored at the edge of the network. In this way, its separation and selection could lead to significant savings. What is more, such approach could help companies to strengthen security issues.
As a response to these issues, edge and fog computing solutions were introduced. While sharing some similar features, these solutions also have some differences.
Pointing Out Differences
When comparing cloud solutions to fog and edge solutions, there are three major factors to consider. These are location, processing power & storage capabilities, and the purpose. Let’s dive into each to highlight the difference between these three options for data storage.
