Edge Computing vs Cloud Computing: Everything You Should Know

edge computing vs cloud computing: everything you should know

Computing is evolving so fast that cloud computing has no longer remained the only technology in the data management field. Some parallel technologies have already made their debut and their future seems to be much brighter. Edge computing is one of those names. Cloud computing is already a successful model with countless future possibilities.

Still, modern computing requirements have some different expectations. In this article, we are going to conduct a comprehensive analysis of both cloud and edge computing. Before diving deeper, let’s clear some basic information concepts.

What is Edge Computing?

Distributed paradigm can be referred to as the term “Edge computing.” It puts data storage and computation power closer to the device or data source that requires it. Information isn’t filtered through distant data centers before being processed in the cloud; rather, the cloud comes to you. This method reduces lag and conserves bandwidth.

Edge Computing, opposite to “IoT,” is a different approach to the cloud environment. It’s all about processing real-time data close to the data source, which is referred to as the network’s ‘edge.’ Instead of using a centralized cloud, data center, or data storage facility, it’s about operating applications as close to the source of the data as possible.

Let’s understand it with a simple instance that most of us experience in our daily life. An Edge computing device is a computer that calculates fuel consumption automatically on the basis of data received from the sensors equipped in a vehicle.

After getting familiar with edge computing, it’s time to have a look at cloud computing technology too. Let’s proceed!

What is Cloud Computing?

Computing as a distributed paradigm is referred to as “Edge computing.” It brings data storage and computation power closer to the device or data source that needs it the most. Information isn’t filtered through distant data centers before being processed in the cloud; instead, the cloud comes to you.

Despite the fact that cloud computing provides far more resources and services than traditional data centers, the nearest regional cloud facility can be hundreds of miles away from where data is collected, and connections rely on the same fickle internet connectivity that supports traditional data centers.

Why Does Edge Computing Technology Need to Come into Existence?

Cloud computing favors a centralized server infrastructure, which isn’t necessarily appropriate in all circumstances. Because data and other related technologies are always improving, a centralized approach isn’t always the best option. Edge computing is capable of handling this issue proficiently by concentrating on processing power.

It provides a practical answer to the growing network issues involved with transporting the massive amounts of data that today’s businesses generate and consume.

Comprehensive Analysis of Edge and Cloud Computing


Differentiation Factors Edge Computing     Cloud Computing
Businesses Compatibility Edge Computing is considered more compatible with high-latency processes. Consequently, it can help medium-sized firms with restricted resources to save money. Cloud computing is a better match for projects and organizations that deal with large amounts of data.
Programming Programming can be done on a variety of platforms, each with its own set of runtimes. Clouds are more suited for actual programming because they are often built for a single target platform and employ a single programming language.
Cybersecurity Edge computing necessitates a comprehensive security strategy that includes improved authentication methods and proactive attack detection. It necessitates a less rigorous security strategy.


  • Sovereignty of data

Edge computing can be utilized to maintain data close to its source while staying within the parameters of existing data sovereignty regulations. For instance, GDPR regulates the way data should be processed, stored, and exposed in the European Union.

  • Smart Automation

This computing technology is beneficial in situations when connectivity is intermittent or bandwidth is limited due to environmental factors. The amount of data that must be sent can be greatly decreased by processing it locally, needing less bandwidth and connectivity time than would otherwise be required.

  • Robust Security

Even if IoT device security is still insufficient, by placing computing at the edge, any data traveling over the network back to the cloud or data center can be encrypted. Moreover, the edge deployment itself can be safeguarded against hackers and other harmful actions.

Applications of Edge Computing

Right now, edge computing technology is aiding multiple industries. Below is a list of its most applications:-

  • Manufacturing industry
  • Network optimization
  • Farming
  • Healthcare infrastructure
  • Workplace safety
  • Retail business
  • Logistics

Final Words

Bandwidth, latency, and congestion are the three major concerns for which edge computing technology came into existence. Still, it cannot replace cloud computing entirely because of the limitations and challenges such as high cost, limited data processing, difficult maintenance, and huge storage requirements. In the computing industry, cloud and edge will complement each other.
