Cloud Computing

Telkomsel describes Cloud computing as a computational model that offers resources such as data storage, processing, and network services over the Internet. With cloud computing, users can access data resources without the need to own or manage infrastructure.

Cloud computing derives its name from the term "cloud," which symbolizes the internet. This term describes a computational model that utilizes a vast infrastructure distributed across the internet.

Cloud computing operates by leveraging a vast computer network that distributes data and user applications stored on servers around the world. Users can access this data and applications through internet services.

Three types of Cloud Computing


1. Software as a Service (SaaS)

This cloud model provides users with software applications. Examples include Gmail, Microsoft Office 365, and Netflix.

2. Platform as a Service (PaaS)

This cloud computing model offers a platform for application development and deployment. Examples include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP).

3. Infrastructure as a Service (IaaS)

This cloud computing model provides computational infrastructure such as data storage, processing, and networking. Examples include Amazon Elastic Compute Cloud (EC2), Microsoft Azure, and Virtual Machines (VM).

Cloud computing key characteristics and benefits


1. Flexibility

Cloud computing offers high flexibility in terms of resources that can be utilized. Users can adjust resources based on their needs.

2. Eficiency

Cloud computing could assist companies in improving efficiency by reducing cost and the resources required to manage computations. With this, companies could reduce cost and resources need by managing the infrastructure alone.

3. Scalability

Cloud computing could assist companies by increasing scalability by easily adjusting the resources required depending on need.

4. Accessibility

Cloud computing aids companies in enhancing accessibility, allowing users to access data or applications from anywhere and at any time.

Disadvantages of Cloud Computing

Because data is stored in the cloud, some people may be afraid that it contains sensitive information. They worry that the data could be hacked or stolen. Another concern is that, when using cloud computing, some data is stored in central data storage. If the locations are different, the jurisdictions could also be different. Therefore, some people are worried about the safety of their data.


Users may not have control over their data, leading to concerns about the cloud infrastructure. The control of data depends on a third party, which users cannot manage or oversee.


Cloud computing is a transformative IT model that revolutionizes data management by utilizing remote servers on the Internet. This approach provides scalable resources, enhancing flexibility and cost-effectiveness. However, concerns arise regarding data privacy and security, as information is stored externally. Despite these challenges, the convenience and efficiency of cloud computing make it a pivotal solution for organizations, requiring a balance between reaping its benefits and addressing privacy and security issues.
