Almost all of us have heard of the term cloud computing - Cloud Computing. However, for edge computing - Edge Computing is a bit strange and rarely hears this phrase. As technology devices become more and more intelligent and sophisticated, and wireless connections take over the world at an increasingly fast pace, edge computing is an important issue that needs attention and development. So, edge computing – What is Edge Computing??
Today's article, Mat Bao will help you better understand this term as well as point out its difference with Cloud Computing and how to effectively apply it, stay tuned!
1. What is Edge Computing?
To be able to define What is Edge Computing? To be precise, we need to briefly discuss cloud computing. Basically, all data processing will happen on devices such as computers, laptops, etc. However, few people know that it can also be processed through the Internet system and the same way. what on a particular device.
The processing takes place on the Internet, outside of these devices is usually supported by cloud computing - Cloud Computing. This is a type of computing formed by a network of servers, connecting the same data center. Accordingly, users will access this system with an Internet-connected device, then they perform data processing tasks on it.
And edge computing - Edge is essentially a form of cloud computing like Cloud. However, the computing needs to be processed will not have to be sent to the original server center, but distributed across many devices. Roughly speaking, Edge is a method of optimizing the Cloud computing system through computing and data processing at the edge of the network, the location closest to the data source.
A specific example: Usually with Cloud, when you do work on Google Docs, each time you type a word, it will be sent immediately to Google's data center hundreds of thousands of kilometers away to process and return the results.
But, with Edge, the words you type will be processed quickly through different devices or small data centers instead of being concentrated in one location for Google, and then transferred back to Google to save. further storage and processing. This helps your requests be processed many times faster, avoiding system overloads or bad transmissions.
2. What is the difference between Edge Computing and Cloud Computing?
As mentioned above, Edge Computing is like cloud computing – Cloud Computing. However, it is more optimized and provides a faster and more efficient way to process data
In addition, this difference is also evident as follows:
- Cloud computing is fast, but not faster than Edge because Edge has a small data center on the edge.
- Edge because of the distribution of many small devices near me, I rarely experience system overload or bad transmission. Meanwhile, Cloud has only one root center, so this problem is very common.
- With Cloud, data has to travel a long distance to reach the origin server, which can cause security risks if Hackers capture a piece of information. In contrast, Edge processes data at the internal device, around it, so it is more secure.
- Cloud bandwidth is easily overloaded when there are billions of devices accessing and sending requests at the same time. Meanwhile, Edge solves this, a part of necessary and important information is processed quickly first, so it will contribute to reducing bandwidth and increasing transmission speed.
3. Benefits of Edge Computing
When I understood What is Edge Computing?Surely you have partly seen the great benefits that it brings. As follows:
3.1. Processing speed
The data can be processed at the origin by the devices with their own computing capabilities, so they are very time-sensitive. This also contributes to reducing data transmission costs, making transmission faster, and improving service quality.
Edge computing – Edge allows to eliminate a large number of “bottlenecks” and many other potential errors in the Cloud.
3.2. Security level
Edge helps to improve the situation of data being stolen and leaked to the outside by having a near processing device that processes important data first and then sends it to a central server. Bad actors will not be able to infiltrate and steal information if they have bad intentions.
In addition, Edge has the ability to unlimitedly scale its internal network as needed without referencing any available storage.
4. Limitations of Edge Computing
Despite possessing many outstanding advantages, Edge still has disadvantages you need to face. Such as:
- Peripheral devices need to have an Internet connection to maximize their utility.
- Currently, these devices also require the computer to have a rather specialized processor chip installed. That's why most edge devices can only really apply data processing to one thing. They are not as flexible as devices on the cloud.
5. Practical Applications of Edge Computing
The potential of Edge Computing in the future is predicted to be extremely powerful. They will be improved better and bring many utilities to a variety of industries and fields. Here are some practical applications where Edge will be used:
5.1. Self-driving car
This field is currently very interested in the world, Vietnam has also started to put businesses into operation. And, Edge is an indispensable factor for the success of self-driving cars.
Edge can help these cars process information instantly and make urgent decisions that bring safety on the road. In addition, Edge also helps vehicles communicate with each other much more effectively.
5.2. Health care equipment
Edge Computing is also getting the attention of the health care and monitoring industry when it comes to creating specialized devices. In the case of telemedicine, Edge can become an effective life-saver.
For example, the Edge app heart rate monitor, which has the ability to separately analyze health data and immediately provide the necessary response to caregivers and alert if you need help. .
5.3. Security solution
Security devices and systems need Edge to prevent threats to their data. Because, it can handle quickly on the spot and immediately warn users to immediately detect suspicious infringement cases.
Edge computing – Edge is a very important solution for application in modern and future devices. Because, it possesses many advantages, more reliable and safer than cloud computing. That's why you should find out now What is Edge Computing? so as not to be surprised with interesting knowledge about it later!
Eye of the Storm Wiki hopes for information and knowledge about What is edge computing? help you better understand this term as well as its applications in today's life fields.
