Cloud computing is the delivery of different services through the Internet, including data storage, servers, databases, networking, and software. We all have heard the word Google Drive in the context of storage and file transfer. What exactly is a drive and what does it do? Let us see. Cloud computing was named to the software and storage services available on the Internet. There is 15GB of free space for Google Drive Storage.
There are three types of cloud computing on the basis of ownership and openness of the cloud. The three types are Public Cloud, Private Cloud and Hybrid Cloud.
1. Public Cloud
Owned by a third-party cloud service provider. It may be free or sold on-demand. It allows customers to pay only per usage for the CPU cycles or storage they consume. The software and services provided by the public cloud are open for all to use and space is maintained and checked by the service provided and can be used through the web browser. The biggest public cloud example is Amazon AWS.
2. Private Cloud
Owned by a single company or enterprise. The private cloud projects require significant engagement to virtualize the business environment and re-evaluate the decisions about the product endorsed and distributed among the peers. It does not really let the idea of the cloud to be used to its fullest. The software or storage here has to pay for the use.
3. Hybrid Cloud
Hybrid cloud is the collation of private, public and community clouds. The hybrid cloud allows different service providers to collaborate and provide services with whatever framework they choose i.e. free or paid. This allows extending the features of the cloud with integration, aggregation, and customization of the hardware and software available on theses platform. A hybrid cloud allows companies to scale computing resources.
We know the types now, but why are organizations turning towards cloud computing? It simply because the six main factors which help decrease the efforts of people on the whole for better work, storage, organize and execute. The six factors are cost, speed, global scale, productivity, performance and security. The expansion of cloud computing is huge and it’s growing as the data entering the internet is in trillions of gigabytes.
There are four major types of services the cloud provides to its users, So, basically, there are four different structures of computing system i.e. Infrastructure as a service(IaaS), Platform as a service(PaaS), Serverless computing and Software as a service(SaaS).
Gmail, Microsoft Office Drive, Apple iCloud, and Google Drive are some of the examples that we use almost every day.
Examples of cloud computing
- It includes services like Gmail or the cloud back-up of the photos on your smartphone. Netflix depends on cloud computing services to run its video streaming service. However, using cloud computing can also introduce new costs and new risks for companies using it.
- Messaging apps like WhatsApp and many more are also based on cloud infrastructure. It allows us to access our information from anywhere via the internet.
- Social media is the most popular application of cloud computing. Some of the social networking sites which use cloud computing are Facebook, LinkedIn, Twitter, etc.
- Microsoft Office and Google Docs also use cloud computing. So, we can work on our spreadsheets and presentation from anywhere, at any time.
Types of cloud services
- Infrastructure as a service (IaaS): It is a form of cloud computing that provides virtualized computing resources over the internet. It is also known as hardware as a service.
- Platform as a service (PaaS): It refers to cloud computing services that supply an on-demand environment. It is because for developing, testing, delivering and managing software applications.
- Serverless computing: It focuses on building app functionality without spending time continually managing the servers and infrastructure required to do so.
- Software as a service (SaaS): It is a method for delivering software applications over the Internet because it is on-demand and typically on a subscription basis.
Advantages of Cloud Computing
- It offers companies from all sectors the ability to use software from any device.
- Users can check their email on any computer and even store files using services such as Dropbox and Google Drive.
- It allows individuals to save storage space on their desktops or laptops and also lets users upgrade software more quickly.
Disadvantages of Cloud Computing
- Lack of security when it comes to important information like financial and medical records.
- Cloud computing companies maintain servers but it can fall victim to natural disasters and internal bugs.
- Using cloud computing on a small scale and for short-term projects can be expensive because the overall price tag could end up being higher than you expected.
So, this was everything that you need to know about cloud computing and I want to say thanks for reading this article.
