Cloud computing are groups of computers and servers connected to each other over the Internet to create a network. Today, just as many companies and large organizations are beginning to take ideas from the Internet of things. There is a growing need for a large amount of data that is faster and locally accessible. Here the term Fog Computing is played.
Cloud computing or clouding is a distributed infrastructure in which a smart device manages the edge of a network with some application processes or services, while others are still maintained in the cloud. It’s an intermediate layer between clouds and hardware to enable more efficient data processing, analysis and data storage, which is achieved by reducing the amount of data that needs to be transferred to the cloud.
How fog computing works
Although high-end equipment and sensors that generate and collect data do not have the computing and storage capabilities to perform advanced analytical tasks and machine learning. While cloud servers have the power to do so, they are often far from timely data processing and response. Also, all endpoints connecting and sending unskilled cloud data over the Internet can have legal, security and security implications, especially if it is confidential information that is regulated in different countries.
In the foggy environment, processing takes place in a data hub on an intelligent device or an intelligent router or gateway, reducing the amount of data sent to the cloud. It’s important to note that the cloud network complements and does not replace cloud computing. Blurring enables short-term edge analysis, and the cloud performs a long-term, intensive analysis.
How cloud computing works
To understand how the cloud computing system works, it’s easier to break it down into two sections: the front and the end.
They are connected to the network, usually over the Internet. The frontend is the side of the computer or the client computer. The back is the “cloud” section of the system.
The frontend consists of a client computer or a network of computers and applications required accessing a computer processing system. It is not necessary for all cloud processing systems to have the same user interface.
At the back of the cloud system are a variety of computers, servers, and data storage systems that make up the “cloud.”
The cloud computing system could include any computer program, from computing to video games. Each application usually has its dedicated server.
Pros of Cloud computing
- Lower Computer Costs: Because applications run in clouds, the desktop does not require the processing power or disk space than traditional desktop software requires.
- Improved Performance: Computers in the system recovery system run faster and faster as fewer programs and processes load into memory.
- Reduced Software Costs: Instead of buying expensive software applications, you can get a bigger share almost for free than you need.
- Up-to-date software updates: When an application is web-based, updates are automatically executed. That is, if you access the web application, you will receive the latest version.
- Improved Document Format Compatibility: Do not worry about the documents you have created on your device that are compatible with other users? Applications or operating systems
Cons of cloud computing
- Common infrastructure restrictions
- With cloud computing, you often access your resources through a globally linked shared resource library, and you’ll probably need to experiment with “noisy neighbors” in this process. However, private cloud services for your business can reduce or eliminate this performance risk.
- Your internet connection will also become an important part of your ongoing work with the cloud computer. Many organizations choose to manage multiple Internet connections with automated failover to reduce the risk of cloud computing outage.
- Security problems
- Incidents like the recent iCloud hacks are obviously anxious. Despite advances in encryption and firewall systems, privacy is still a legitimate threat to the cloud.
- Technical regulations and interruptions
- Nothing is 100% immaculate. Even the biggest names in cloud services have been faced with pauses and network issues in the past. Many organizations need an uninterrupted connection to the cloud features they want. Cloud and Internet providers do not always guarantee this burden.
Pros of Fog computing
- Bring data close to a user. Rather than reporting on data center hosting far from the endpoint, the nebula wants to bring data close to the end user.
- Real Mobility Support and Internet Intelligence. By controlling data across multiple edge points, the mainframe complements the core cloud services with those of a truly distributed data center. The more services are created for the benefit of the end user, the more common are edge and haze networks.
- Numerous verticals are ready to be accepted. Many organizations already accept the term mist. Many different types of services typically provide rich content for the end user. Also contains IT shops, providers, and artists.
Cons of Fog computing
- Physical Location: There are some who claim that the whole purpose of the cloud is accessing data and resources from anywhere, regardless of physical location. While cloud computing only works as a more selective way of identifying data that is centralized and local, some believe that the limitations of the latter are disadvantages in terms of accessibility.
- Safety: Safety has long been preserved as the fifth Achilles leap, but given the many developments in this area in recent years, safety issues are indeed a matter of trust. Certain organizations feel more comfortable because they have their data in a central location, not remote and of different types – although the old option can degrade data management when viewed globally.
- Confusion: There is also the prospect that the ease of cloud computing only increases the number of cloud options (public, private, hybrid, cloud, etc.), unnecessarily complicating the already complex architecture. Obviously, those respondents would have the same opinion about the internet in general.
Although fog computing and cloud computers allow storage, applications, and data for end users, fog computing has a greater proximity to end users and greater geographic distribution.
