Basics of cloud computing

Cloud computing has fundamentally changed the way businesses, educational institutions, and individuals approach technology. Instead of relying on local servers or personal devices, we now access powerful computing resources, storage, and services over the internet. This shift not only democratizes access to advanced technology but also fosters innovation, flexibility, and inclusion—including for neurodivergent learners and professionals entering the tech workforce.

Understanding the Cloud: More Than Just a Buzzword

Cloud computing refers to the delivery of computing services—such as servers, storage, databases, networking, software, analytics, and intelligence—over the internet, or “the cloud.” The main idea is to provide faster innovation, flexible resources, and economies of scale. Instead of maintaining physical hardware or installing software locally, users can leverage cloud services on demand, paying only for what they use.

Imagine a library where you can borrow any book, anytime, from anywhere, without worrying about shelf space or due dates. That’s the promise of cloud computing, but with data, applications, and infrastructure.

This approach transforms not just IT departments, but also learning environments and the way neurodivergent individuals access tools that suit their unique cognitive styles. Cloud platforms make it easier to experiment, learn, and build solutions without the traditional barriers of cost and complexity.

Key Characteristics of Cloud Computing

To appreciate the potential of cloud technologies, it’s helpful to recognize their defining features:

• On-demand self-service: Users can provision resources as needed, without human interaction with the provider.
• Broad network access: Services are available over the network and accessed through standard mechanisms, supporting diverse devices.
• Resource pooling: Providers serve multiple customers with dynamically assigned physical and virtual resources, according to demand.
• Rapid elasticity: Capabilities can be elastically provisioned and released, scaling quickly to meet requirements.
• Measured service: Resource usage is monitored, controlled, and reported, offering transparency for both provider and consumer.

These characteristics make cloud computing especially powerful for education, startups, and organizations aiming to foster diversity in tech, as they lower traditional barriers and support a wide range of learning and working styles.

The Service Models: IaaS, PaaS, SaaS

Cloud computing services are typically delivered through three primary models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). Each model offers a different level of control, flexibility, and management.

Infrastructure as a Service (IaaS)

IaaS provides the fundamental building blocks of cloud IT. It offers virtualized computing resources over the internet. With IaaS, users rent IT infrastructure—servers, virtual machines, storage, networks, and operating systems—from a cloud provider.

Example: Amazon Web Services (AWS) EC2 and Microsoft Azure Virtual Machines are classic IaaS offerings. They allow organizations to build custom environments, scale up or down as needed, and pay only for what they use.

IaaS empowers tech-savvy learners and organizations to explore operating systems, networking, and security in a safe, scalable, and cost-effective way.

For neurodivergent technologists, IaaS can offer the freedom to create highly personalized environments—tailoring interfaces, scripts, and workflows in ways that best match individual cognitive preferences.

Platform as a Service (PaaS)

PaaS sits one level above IaaS. It provides a framework for developers to build, test, and deploy applications without worrying about underlying infrastructure. PaaS manages servers, storage, networking, and even some aspects of security, enabling users to focus on the creative and functional aspects of app development.

Example: Google App Engine, Heroku, and Microsoft Azure App Service allow developers to launch web applications with just a few commands, scaling automatically as usage grows.

Why does this matter? PaaS platforms are particularly valuable for educational environments and collaborative projects. They simplify the process for new developers—especially those from non-traditional backgrounds or with neurodivergent perspectives—by removing many of the technical hurdles that can make entry into tech daunting.

PaaS is like a digital playground: the infrastructure is taken care of, so you can focus on building, experimenting, and learning.

Software as a Service (SaaS)

SaaS is the most familiar cloud service model for most users. It delivers software applications over the internet, on demand and typically by subscription. With SaaS, users access and use applications via a web browser, while the provider manages everything else—servers, storage, security, and updates.

Example: Google Workspace, Microsoft 365, and Salesforce are leading SaaS products. They enable collaboration, communication, and productivity from any device, anywhere in the world.

SaaS and inclusivity: These tools break down accessibility barriers for neurodivergent users and remote learners by offering features like real-time collaboration, voice input, screen readers, and customizable interfaces.

SaaS levels the playing field, letting everyone—from students to professionals—access world-class software without installation headaches or high upfront costs.

Deployment Models: Public, Private, Hybrid, and Community Clouds

Cloud services can be deployed in several ways, each offering different levels of control, security, and flexibility:

• Public cloud: Services are delivered over the public internet and shared across multiple organizations. This is the most common model for SaaS, PaaS, and IaaS.
• Private cloud: Services are maintained on a private network, dedicated to a single organization. This model offers greater security and control, often used by large enterprises or institutions with specific regulatory requirements.
• Hybrid cloud: Combines public and private clouds, allowing data and applications to move between them. This approach maximizes flexibility and is popular among organizations with diverse needs.
• Community cloud: Shared infrastructure for a specific community with common concerns, such as compliance or security needs. This is less common but valuable for sectors like education or healthcare.

For educators and organizations serving neurodivergent or underrepresented groups, hybrid and community clouds offer a balance between accessibility, customization, and privacy.

Advantages and Opportunities in Cloud Computing

The impact of cloud computing reaches far beyond technical efficiency. It is transforming learning, collaboration, and career opportunities, especially for women, non-binary individuals, and neurodivergent technologists who have historically faced obstacles in traditional IT environments.

Accessibility and Inclusion

Cloud-based tools and platforms can be tailored to different learning and working styles. Features such as screen readers, customizable interfaces, real-time transcription, and AI-powered assistance make technology more accessible than ever before.

The cloud is not just about infrastructure—it’s about creating space for every mind to thrive, regardless of how it works.

Scalability and Flexibility

Whether you’re a startup founder, an educator, or a student launching your first web application, the cloud offers scalability that was once reserved for large enterprises. You can start small and grow as your needs evolve, without major upfront investments.

For learners and professionals with varying schedules or working styles, cloud-based environments mean they can access resources at any time, from any device, in a way that fits their routines and preferences.

Collaboration and Experimentation

Cloud platforms encourage experimentation and rapid prototyping. Version control, real-time collaboration, and integrated development environments (IDEs) allow teams to work together across geographies and time zones, accommodating diverse contributors and neurodivergent thinkers who may approach problems from unique angles.

Security and Privacy Considerations

With all its benefits, cloud computing also brings new challenges. Security, privacy, and data sovereignty are critical concerns for organizations and individuals alike.

Key best practices include:

• Understanding shared responsibility: Providers secure the infrastructure, but users must secure their own data and applications.
• Implementing strong authentication and access controls.
• Encrypting sensitive data, both in transit and at rest.
• Regularly updating software and monitoring for vulnerabilities.

Security in the cloud is a shared journey. It requires both technical vigilance and a culture that values privacy and trust.

For neurodivergent users and those new to technology, cloud providers often offer clear documentation, automated tools, and accessible support channels to help navigate these complexities.
