Demystifying Cloud Computing: How It Works and Its Pros and Cons

In the era of digital transformation, data has become a valuable resource for organizations, but the costs of storing and operating traditional IT infrastructure are becoming a burden. Is your organization missing the opportunity to lead because its data potential is untapped? How can you optimize costs and scale flexibly while still ensuring rapid strategic decision-making? Join 1Office to explore Cloud Computing storage technology and seize the opportunity for effective digital transformation.

1. Demystifying Cloud Computing Technology in Simple Terms

Cloud Computing is a modern information technology service delivery model that allows businesses to access and use computing resources such as servers, storage, software, and data over the internet without needing to invest in or manage complex physical infrastructure.

This helps businesses shift from a model of large capital expenditures to flexible operating expenses, optimizing resources and adapting quickly to market changes.

The Structure of Cloud Computing

Cloud Computing is composed of three main components:

• User Interface (Front End): Ensures a seamless and flexible access experience on any device through web browser-based Thin Clients, or provides more powerful operational capabilities with specialized Fat Clients.
• Back-end Platforms: The powerful core, built from a diverse system of servers to ensure the capacity for storing and processing massive amounts of data.
• Network and Cloud-Based Delivery Services: Includes the Internet, Intranet, and Intercloud (different cloud services connecting and interacting with each other).

2. Classifying Cloud Computing Models

Cloud Computing is classified into two groups based on deployment models and service models.

2.1. Classification by Deployment Model

Public Cloud

Classification of Cloud Computing Deployment Models

Public Cloud is understood as a public cloud where a service provider shares cloud resources among multiple businesses. The key advantages of Public Cloud are low initial investment costs and rapid deployment speed. However, businesses need to pay special attention to data security policies, as the infrastructure is shared with many other users.

Private Cloud

This private cloud model is designed exclusively for a single enterprise. It can be located in an internal data center or outsourced but does not share resources. Private Cloud offers superior security and absolute control, making it ideal for businesses with strict regulatory and data security requirements.

Hybrid Cloud

Hybrid Cloud is a combination of Private and Public Cloud

A combination of Public Cloud and Private Cloud, it helps businesses leverage the advantages of both models. Critical data and applications can be stored on the Private Cloud, while other services use the Public Cloud to save costs.

2.2. Classification by Service Model

Software as a Service (SaaS)

SaaS provides complete, ready-to-use software applications over the internet. Users access the software via a browser or an app without installation, and the provider is responsible for maintaining, upgrading, and operating the entire system.

Technological characteristics:

• The software is designed for multi-tenancy, ensuring it can serve thousands of customers simultaneously.
• Automatic and continuous updates ensure you always have the latest, most secure, and stable version.
• API integration allows for easy connection with other systems.

SaaS is suitable for businesses that want to quickly use standardized solutions like business email, customer management, and employee collaboration without investing in developing or maintaining their own software. Examples: Gmail, Salesforce, Microsoft 365, Zoom.

Platform as a Service (PaaS)

PaaS provides a complete platform to develop, run, and manage applications without worrying about the physical infrastructure or operating system. The provider handles all the infrastructure, databases, and development environment, helping users focus on building and deploying software.

Technological features:

• Integrates development tools, middleware services, database management systems, and built-in security and monitoring systems.
• Supports automatic scaling, load balancing, backup, and data recovery.
• Allows developers to work faster and more efficiently, focusing on coding and business logic.

Infrastructure as a Service (IaaS) – Infrastructure as a Service

The three main services of Cloud Computing

IaaS provides technology infrastructure including virtual servers, storage, networking, and computing resources via the cloud platform. Users rent these resources, and they manage the operating system, middleware, applications, and data themselves.

Technological features:

• Virtualization is the core technology that allows for the flexible creation and distribution of infrastructure resources.
• Resources can be scaled up or down instantly according to actual demand.
• Users have nearly complete control over the system on the cloud infrastructure without needing to invest in physical hardware.

This model is suitable for businesses that want to build and manage their own IT systems, develop custom applications, or migrate existing systems to the cloud while retaining control. Some prominent services include Amazon Web Services EC2, Microsoft Azure Virtual Machines, and Google Compute Engine.

3. How does Cloud Computing work?

The operational mechanism of Cloud Computing revolves around the principle of sharing computing resources over the Internet, completely eliminating the burden of managing on-premise physical infrastructure. 

Instead of making large investments in purchasing and operating their own servers, businesses can leverage the power of thousands of powerful servers in the service provider’s data centers. These servers are tightly interconnected, forming a unified system that provides computing resources (CPU, memory), storage, and essential services to millions of users simultaneously. When a business chooses a cloud service, access to resources is granted via the Internet. 

How Cloud Computing works

Access to resources is done via the internet, while the hardware, maintenance, and backups are all handled by the provider. Businesses simply use the service and pay based on the actual resources consumed.

Here is an illustrative example to help you visualize how Cloud Computing is applied in the workplace:

“To better visualize a practical application, consider a business implementing HR management software on a cloud platform like 1Office. Instead of investing in installing and maintaining the system on individual computers or local servers, all HR data – from timesheets to payroll – is securely stored and processed on cloud servers managed by the provider. 

This allows employees and managers to access the system anytime, anywhere with just an Internet connection and a web browser or mobile app. All information updates are synchronized instantly, ensuring data is always accurate and transparent, supporting timely decision-making and improving operational efficiency.”

4. Which businesses are suitable for implementing Cloud Computing?

Cloud Computing is a universal technology that provides outstanding value to a wide range of individuals, organizations, and businesses of all sizes and industries. In particular, the following sectors have a great opportunity to break through in operational efficiency by applying Cloud Computing:

E-commerce Industry

The e-commerce industry is characterized by a large volume of orders and constantly changing customer data. Effective management requires a technology system with flexible scalability and rapid data synchronization. Cloud Computing is the ideal solution for these reasons:

• Capacity to process large data volumes and synchronize orders instantly: Ensures real-time order tracking, inventory management, and transactions, minimizing errors and enhancing operational efficiency.
• Flexible scalability according to business cycles: Automatically increases or decreases server resources, helping businesses proactively adapt to market fluctuations and optimize costs.
• Significantly reduces physical infrastructure investment costs: Businesses do not need to purchase or maintain expensive servers, instead paying only for the resources they actually use.
• Enhances customer experience with stable, high-speed services: Ensures websites and applications run smoothly without interruption, even during peak traffic periods.

Information Technology and Software Industry

Software development requires space for testing

Businesses in the information technology and software development sector need an environment to test, develop, and deploy applications. Cloud Computing provides on-demand technology platforms and infrastructure. Some noticeable benefits include:
