I. Understanding Cloud Computing in Education

Cloud computing in education can be simplified as a way of using computer services over the internet to make things easier and more efficient for schools and students. Instead of buying and owning computer equipment like servers and storage, it’s like renting these services when you need them, kind of like borrowing a library book.

What is Cloud Computing in Education?

Think of cloud computing as a virtual toolbox for schools. It includes various tools like computers, storage space, and software that are available online. These tools can be used whenever teachers and students need them, without having to worry about the technical stuff behind the scenes.

False beliefs about Cloud in Education

• Cloud is not safe for School Data!
  In fact: It highly depends on Cloud providers, like Alibaba, Google and Microsoft, take security seriously. They use strong locks and alarms to protect your data. In fact, most data breaches happen because of mistakes people make, not because of the cloud. According to Gartner, through 2022, at least 95% of cloud security failures will be the customer’s fault, not the provider’s.
• Cloud Always Cost More!
  In fact: Not really. Cloud services can be cheaper because you only pay for what you use.  In reality, the pay-as-you-go model can be cost-effective as organizations pay only for what they use. For instance, AWS reported that its customers achieved an average of 30-40% savings by moving to the cloud. It’s like paying for electricity – you don’t pay when you don’t use it. Schools can save money by not needing to buy and maintain expensive equipment.
• Is My Data Private in the Cloud?
  In fact: Yes, cloud providers have strong rules to keep your data private. They follow laws that protect your information. For example, they won’t share your student’s grades with anyone without permission.
• Do I Need to Be a Computer Expert to Use the Cloud?
  In fact: No, cloud providers make it easy. It’s like using a smartphone – you don’t need to be a computer genius. They even have classes and guides to help teachers and students learn.

To put it simply, cloud computing in education is like having a magical toolbox of computer tools that you can use whenever you need them, and it’s safe, cost-effective, and easy to use.

II. Cloud computing service models

Cloud computing can be categorized into three main service models: Iaas, Paas and Saas

Infrastructure as a Service (IaaS) in Education

• Definition: IaaS in education refers to the cloud service model that provides virtualized computing resources, including virtual machines, storage, and networking, for educational institutions. It enables schools to create, manage, and scale their own IT infrastructure.

For instance, they could use Alibaba Cloud Elastic Compute Service (ECS) to create and manage virtual servers. They can customize these servers based on their computing needs, such as allocating resources for hosting web applications, databases, and research tools.

Platform as a Service (PaaS)

• Definition: PaaS in education involves cloud platforms that provide development and deployment environments for creating custom educational applications and solutions. It abstracts infrastructure complexities, allowing developers to focus on building educational software.

Example: A university might use a PaaS to develop a custom mobile app for students to access course materials and campus resources. By using a PaaS like Google App Engine, developers can focus on app development without managing underlying infrastructure.

Software as a Service (SaaS)

• Definition:  SaaS is a cloud service model where software applications are hosted in the cloud and made available to users over the internet. Users access these applications through web browsers without the need for local installation and management.
  SaaS delivers software applications over the internet on a subscription basis.

Example: Alibaba Cloud’s “Smart Classroom Management System” is a SaaS solution tailored for the education sector. It offers a comprehensive suite of tools that enable educators to manage and streamline classroom activities, from attendance tracking and resource sharing to interactive teaching.

USDC Technology is the strategic partner of Alibaba Cloud who offers a range of cloud services that encompass all three main service models: IaaS (Infrastructure as a Service), PaaS (Platform as a Service), and SaaS (Software as a Service). This provides customers with a comprehensive set of options to meet various IT and business needs.

Google Workspace (formerly G Suite) provides a suite of productivity applications such as Gmail, Google Docs, and Google Sheets that users can access and use online without installing any software on their local devices, widely used in education for productivity and collaboration
