In today's digital era, cloud computing has become an important component in business operations. A research published by the University of Indonesia's Faculty of Computer Science, the National Cyber and Crypto Agency, and the Indonesian Cloud Computing Association in February 2022 revealed that 67% of the public sector in Indonesia is already using cloud computing as part of their digital transformation.
One of the main factors driving the adoption of cloud computing is the acceleration of digital marketing and increasingly fierce market competition. Public cloud, being the most frequently used cloud computing service model because it offers convenience, scalability, and high flexibility. With these capabilities, public cloud is a solution that is widely adopted by the public and business sectors in carrying out digital transformation.
However, what is public cloud exactly? Let's find out more about the public cloud, how it works, and what benefits it offers in this article.
Definition of Public Cloud
Public cloud is one of the cloud computing service models that can be used by many users (multitenant). Public cloud service providers will provide ready-to-use infrastructure and resources, so you as a user do not need to own hardware and manage infrastructure yourself, just pay according to usage.
What distinguishes the public cloud from the other 2 cloud models, private and hybrid cloud? The difference is in the infrastructure. Public cloud infrastructure can be accessed by many users and managed by a third party provider or cloud provider. Meanwhile, p rivate cloud is designed specifically for one organization, giving its users more control over data and security but at a higher cost of building its infrastructure and managing it. Hybrid cloud combines private and public cloud infrastructure, allowing organizations to store sensitive data in a private cloud while utilizing the flexibility and scalability of the public cloud.
With its scalability and flexibility, the public cloud is suitable for uses that require easy access and scaling and do not require high security. Examples of using the public cloud include hosting websites and applications, installing software such as m365 and google workspace, analyzing big data, development and testing, and many more.
How Public Cloud Works
Public cloud infrastructure is provided in full by the service provider. This infrastructure includes large data centers consisting of servers, storage, networking, virtualization, and other cloud computing resources. This infrastructure and resources are then shared by many users.
In addition to providing infrastructure, public cloud service providers also help manage all technical aspects, including security, maintenance, and system updates, handled by the cloud service provider. That way, you only need to focus on developing the application without worrying about the technical needs of the cloud.
Benefits of Public Cloud
Public cloud has many advantages that can be utilized by various industries and business levels. The advantages of the public cloud include:

| Security | Data security depends on the security quality of the service provider. | Higher security due to full control of the user. | More flexible security, sensitive data can be stored in the private cloud. |
| Scalability | Very flexible, can adjust server capacity as needed. | Less flexible because it takes a long time, and more effort and investment to scale. | Flexible, can use public cloud for large workloads. |
| Ease of Management | Easy to use, no need for a dedicated IT team to manage. | Need a dedicated IT team for management and maintenance. | Requires more complex management to integrate two types of cloud. |
| Examples of Suitable Industries | Startups, e-commerce, tech companies, media, and businesses that require high scalability at low cost. | Financial companies, government, hospitals, or businesses that handle sensitive data. | Large enterprises, manufacturing industries, and companies that want a balance between performance and security. |
Challenges in Using Public Cloud
Although it offers various benefits, there are several challenges in using the public cloud that you must know. Some of these challenges include:
