Cloud Computing vs Edge Computing. Which is Better?
Introduction
Cloud Computing vs Edge Computing is one of the most common trends that top software development companies in India are concerned about. But, before comparing these to identify which one is the better one, if you are a beginner in this field, you need to understand what exactly these two are and how these work differently. In this blog, we are going to offer a clear understanding of these two different computing systems along with their different applications, advantages, and a comparison between these to find out the better one.
Understand Cloud Computing With Example
When we use the Internet as a cloud or virtual space to provide various computing services like storage, database, software, network, and analytics through the Internet itself, then the whole process is called Cloud Computing.
It is named ‘cloud’ because the information that we get access to, is located remotely in a virtual space. This virtual space is referred to as a ‘cloud’. Big companies for web development services (like Google/ Microsoft/ Amazon, etc) let their users store files and data on remote servers, which can be accessed anytime through the Internet.
A few services that are now so important in our daily lives like email, data storing, backup and retrieval, creating applications, testing codes, data analyzing, online streaming of video and audio, and much more are based on Cloud Computing principles.
Understand Edge Computing With Example
Edge Computing refers to a distributed model of Cloud Computing architecture, where the user’s data gets processed within a specific range of the network, closer to its originating source.
Few ranges networks and computing devices take away a part of storage and compute resources from the central data center, i.e., the cloud, and process the user-generated data near the source of that data itself. This does not require transmitting the raw data to the cloud center for the purpose of processing and analysis, rather this job is done right at the original source of the data. Only the results like real-time insights analyzed predictions, and actionable decisions are sent to the supreme cloud data center for review.
Some devices that are non-negotiables in our daily lives like smart watches, smart speakers, smartphones, and smart TVs, (also self-driving cars) work on Edge Computing models.

In response to traffic flow, the Edge Computing empowered traffic lights can change in real-time, resulting in reduced traffic and smoother travel.
Benefits of Cloud Computing
Cloud Computing is an older model that has benefitted users for over 2 decades now. Let’s have a look at the benefits of Cloud Computing,
Enhanced collaboration and productivity
As Cloud Computing is independent of a fixed tangible place, employees can communicate with each other in real-time and remotely. The data is centralized, user location does not matter.
Unlimited storage
It enables users to store, access, and retrieve data via remote devices. This process does not involve local storage devices.
Less hardware cost
We use remote servers. As a result, the maintenance and managing charges of centralized hardware are much less.
Central provisional services
Cloud-based models can be created within a few hours. Because cloud system providers customize their pre-configured processes according to the user’s needs.
Flexibility and mobility
Users can access data from anywhere. For example, remote employees who are away from their office location can access crucial data via mobile phones stay connected with clients, and coworkers, and work on their business goals.
How Edge Computing Gets an Edge over Cloud Computing
Here we will learn about the factors that give Edge Computing an edge over Cloud Computing.
Speed
As applications and data analysis tools remain closer to the source of data, the distance that data has to travel gets reasonably reduced and thereby the time needed for that transfer. The process also reduces network congestion and increases speed and responsiveness. That’s why the service quality of Edge Computing is better.
Reduced latency
Edge Computing works in a distributed network system, unlike Cloud Computing. Edge Computing refers to a distributed model of Cloud Computing architecture, where the user’s data gets processed within a specific range of the network, closer to its originating source. The devices of the user, heavy traffic, and data processing units stay in close contact, which automatically reduces latency and promotes real-time decision-making.
Reduces Costs
Local edge data centers store and process data that allows businesses to operate IoT devices with less bandwidth. This significantly reduces the heavy costs of running centralized data centers.
Can Edge Computing replace Cloud Computing?
This is the most asked question of concerned developers from top software development companies in India and around the world. But the fact is when the question arises as to whether Edge will be able to replace Cloud services in the future, you can rest assured that this will not be the case. These two different computing models serve different needs of an organization. Edge Computing refers to local small data centers that reduce some burden off the cloud just like a regional office that deals with local computing issues rather than sending it to a central data center, i.e., Cloud which is located miles away working remotely. In the case of Cloud Computing, the expense, effort, and time of setting up an IT infrastructure gets replaced with a remote set of applications that offer the same services. Cloud Computing does the heavy lifting of the major workload. This is why it is impossible for any one of the two to replace each other, rather both are complementary to each other.
Conclusion
As we explore cloud and Edge Computing, you have to keep in mind that there isn’t a single solution that is best for everyone. Every technology has its own advantages and disadvantages, and the best option will depend on the desired features of your applications as well as your company’s goals. Knowing the fundamentals of these two computing technologies enables you to make more informed decisions for your mobile app development company or any other business application. In today’s tech-driven environment, regardless of whether you choose the edge’s fast answers and large storage capacity or the cloud’s massive storage and power, understanding the areas of application is crucial.
