Cloud computing is a way to access data and resources that are not located in the same location as where the data or resource is used. Cloud computing provides a centralized, virtual system of specialized computers that store data and resources in one location – called the cloud. This system can be accessed from anywhere there’s an internet connection.
The cloud computing industry offers end-user applications, storage, and software services over the internet. Cloud Computing Services can be broken down into four classes: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Software as a Service (SaaS).
Effect of Cloud on Human Lives:
- Cloud computing has had a great impact on the lives of humans. It has helped save time and money while also providing unprecedented access to information.
- Since cloud computing relies on the internet, it is always on and available even when you are not.
- The following are some benefits it can provide:
- Cloud computing can be accessed on any device with an internet connection. This means that you can work from either your laptop, your phone, or your tablet no matter where you are.
- With Cloud storage, files do not need to be moved or copied from one device to another in order to be accessible by other devices, which saves both time and money.
- The app just needs to connect to the other device (e.g. using a remote desktop software) so you can have full access to your files and folders on that device.
Prerequisite to learn cloud computing
To understand cloud technology, readers should first know about Networking, computers, databases, etc. Terms such as operating system and applications should be familiar before beginning this
- Low Hardware Costs: Cloud-based applications require very little in terms of hardware. One can find that they don’t have an expensive computer or the latest in hardware to match and because of such, running these kinds of applications becomes a much more attainable cost.
- Storage capacity: Cloud storage capacity is unlimited and can provide 2000+ GB’s of space for use.
- Low cost of IT infrastructure: Cloud technology, as discussed earlier, can reduce the cost for an organization. You won’t need to hire IT staffs or server engineers because a single OST will handle all your information needs.
- Increase computing power: Cloud servers are good for running and processing tasks, as well as for handling high demand applications.
- Reduce Software Costs: Cloud computing has changed the way we think of software costs. While not everyone has accepted this change, those who have seen its benefits are very grateful for it. For one, every organization or company doesn’t need to purchase the software to use on a variety of computers, and if they do, you also won’t be spending as much money as it’s just a subscription fee.
- Updating: When using Instant software update, you’re able to avoid a choice issue between old/obsolete and new/upgraded software with just one click.
The Latest paradigm
Cloud computing is a technology which has caused the real paradigm of technology to change. Cloud computing was enabled by the trend of the Internet and by some famous multinational companies.
The concept of cloud computing enables a user to make their dream happen. It is based on the idea that devices can be shared and pay incurred as they are used. Furthermore, cloud architecture accommodates infinite scalability and an available system with high-speed accuracy.
Cloud computing is a way of using the cloud to host your data and applications. It’s like the internet for your business – you pay only for what you need, when you need it.
Disadvantages of cloud computing
- Internet speed: Cloud technology is dependent on high speed internet connection, which often requires a lot of bandwidth in order to operate
- A constant internet connection: its is required to use cloud infrastructure. To access any application or storage space, you need an internet connection.
- Security: Data security is not always guaranteed. With cloud computing, a person could gain access to information if it is uploaded and stored on the cloud computer.
Cloud Model Types
- In this section, we will discuss the three types of cloud models: public, private, and hybrid.
- The public cloud is a service that is run by a third party, which makes it available for anyone to use. You can access it through the internet as a web service. The most popular example of this is Google’s Gmail.
- The private cloud is set up and maintained by an organization for its own use only. It has different levels of security and privacy than the public cloud does—more like what you would find in an office building or campus. For example, companies might use this type of system to store sensitive data like financial records or employee information—something they don’t want leaking out into the open internet.
- The hybrid model mixes two different clouds together:
