Cloud computing is a technology that allows users to store, manage, access data, and run applications over the internet.
Users do not need physical hardware or storage space when saving data or running applications. By using the internet, all computational resources can be accessed remotely.
To access this service anytime and anywhere, users only need an internet connection.
How Does Cloud Computing Work?
The cloud system works by providing various computing services through a network of remote servers connected via the internet.
The data stored in the cloud is not on the user’s local device but on remote servers owned by the cloud service provider.
When users access data or applications, their requests are sent to the cloud server, and the results are then sent back to the user’s device.
The use of virtualization technology enables physical servers to be divided into multiple virtual servers. This allows resource usage to be more efficient and flexible.
Types of Cloud Computing by Service Model
There are three main types of cloud computing services that users can choose from, based on their needs:
- Platform-as-a-Service (PaaS)
PaaS provides a complete platform for developing, testing, and deploying applications without worrying about the underlying infrastructure.
Developers can focus on building applications while the cloud service provider manages the servers, storage, and network.
Examples of PaaS services include Google App Engine and Microsoft Azure.
- Infrastructure-as-a-Service (IaaS)
IaaS offers IT infrastructure such as servers, networks, and storage that users can rent without having to purchase physical hardware.
This service is ideal for companies needing high scalability.
Examples of IaaS services include Amazon Web Services (AWS) and Google Compute Engine.
- Software-as-a-Service (SaaS)
With SaaS, users can access software applications over the internet without having to download or install them on their devices.
SaaS is often used for business applications like email and team collaboration.
Examples of SaaS services include Google Workspace and Microsoft Office 365.
Types of Cloud Computing by Deployment Model
Cloud computing can also be categorized based on deployment models:
- Public Cloud
Public cloud services are accessible over the internet to anyone. Examples include AWS and Microsoft Azure.
- Private Cloud
Private cloud services are dedicated to a single organization, making them more secure and controlled.
- Hybrid Cloud
A hybrid cloud is a combination of public and private clouds. It allows businesses to store sensitive data on a private cloud while using a public cloud for general operations.
What Are the Benefits of Cloud Computing?
Cloud computing offers several advantages, such as:
- Cost savings on initial infrastructure
- Flexibility and easy scalability
- Advanced data security provided by cloud service providers
- Access to data from anywhere
What Are the Drawbacks of Cloud Computing?
However, cloud computing also has some drawbacks:
- Dependence on internet connection
- Privacy risks if sensitive data is stored in the cloud
- Ongoing subscription costs for cloud services
Applications of Cloud Computing
In addition to providing various services, cloud systems also serve several functions, including:
- Email services, such as Zimbra Mail
- Data storage, backup, and retrieval
- Application development and testing
- Data analysis
- Audio and video streaming
Cloud computing is already being used by many organizations, from small businesses to large corporations, government agencies, and individual users.
Other cloud services include language processing, artificial intelligence, and standard business applications.
Physically, you no longer need to be in front of a computer or laptop when utilizing cloud systems.
Cloud Computing in Business
If a business is planning to move to the cloud, they need to assess their current IT infrastructure.
Several factors to consider include the costs of maintaining a data center, rental fees, hardware costs, software costs, CPU specifications, RAM, and more.
You also need to decide whether to discard or rebuild infrastructure for the cloud or use a SaaS package.
Each option comes with different costs. For example, companies may need to consider the cost of additional employees when using cloud systems.
Cloud computing in business can be used in various ways.
Some users place all their applications and data in the cloud, while others use a hybrid model.
In a hybrid model, only some applications or data are stored on a private server, while the rest are placed in the public cloud.
