How cloud computing began
In the early days of business computing services, IT departments managed sprawling server rooms filled with hardware to store data, run applications, and support business operations. This approach was expensive, time-consuming, and limited by the physical constraints of on-site systems.
The late 1990s and early 2000s saw a major shift as businesses began to explore offloading some of this burden. Early pioneers like Salesforce introduced software as a service (SaaS) in 1999, allowing companies to access customer relationship management (CRM) tools through the Internet. This move marked the first step toward what we now call cloud computing.
The concept gained traction as tech giants like Amazon, Microsoft, and Google built massive data centers to host and manage computing resources remotely. In 2006, Amazon Web Services (AWS) led the charge by offering businesses a way to rent computing power and storage on demand. This play by Amazon set the stage for the future of cloud computing—companies no longer needed to invest in expensive hardware to keep up with their growing needs.
Over the next decade, cloud computing continued to evolve. It moved beyond simple storage solutions, with services like platform as a service (PaaS) and software as a service offering tools to build apps, analyze data, and manage operations—all without requiring significant upfront investments. Suddenly, businesses of all sizes could access the same technology that big corporations used.
Today, businesses use cloud computing for everything from storing data to powering custom-built AI solutions. What began as a way to streamline IT capabilities has become a standard resource for managing day-to-day tasks while staying prepared for growth. With cloud and computing capabilities, businesses can scale effortlessly, access cutting-edge technology on demand, and adapt to new opportunities—all at the flip of a virtual switch.
Types of cloud computing
Cloud computing offers a range of setups to suit different business needs. Some focus on flexibility, allowing you to scale and adapt quickly, while others prioritize security for handling sensitive data. You can even choose a mix to get the best of both worlds.
Public cloud services
Public clouds are shared systems offered by providers like AWS, Microsoft Azure, and Google Cloud. They let multiple businesses use the same technology, but each company’s data and apps are kept completely secure and separate. It’s an easy way to access advanced tools without the cost or hassle of maintaining your own hardware.
Private cloud services
A private cloud is designed for a single company, giving it full control over its data and systems in a dedicated environment. Unlike public clouds, where resources are shared among multiple users, a private cloud ensures that all data and applications remain isolated, making it ideal for industries like healthcare and finance that require high levels of security and strict compliance. This setup allows businesses to customize the cloud to their specific needs while still benefiting from the flexibility and scalability that cloud computing provides—all without sacrificing control or security.
Hybrid cloud services
Hybrid clouds combine public and private cloud services into a unified system, giving businesses the best of both worlds. This approach allows sensitive data and critical workloads to stay secure in a private cloud while the public cloud handles less sensitive tasks or sudden spikes in demand.
For instance, a company could store customer data securely in its private cloud while leveraging a public cloud to perform data analytics or handle seasonal traffic surges. Hybrid clouds are an ideal choice for businesses that require flexibility and scalability but also need to maintain control over their most important data and applications.
Multiple cloud computing services
Multi-cloud computing allows businesses to use services from multiple providers instead of being tied to just one. For example, a company might use one provider for email and another for data storage. Some may even go a step further and run a single product across multiple clouds—like MongoDB Atlas, which lets you deploy databases wherever it makes the most sense. Multi-cloud is a smart option for businesses looking to stay flexible, improve performance, or reduce their reliance on any single provider.

Understanding the different types of cloud setups is just the first step. Once you know which model fits your business, it’s time to look at the specific services cloud technology offers, such as infrastructure as a service (IaaS), platform as a service, and software as a service.
Breaking down cloud computing services: IaaS, PaaS, and SaaS
Cloud technology isn't just about where your data lives—it's also about how you use it. Cloud services come in three main types: infrastructure as a service, platform as a service, and software as a service. Each offers a different level of control and convenience, depending on your business needs. Let's take a closer look.
Infrastructure as a service (IaaS)
IaaS delivers the core components of cloud computing—storage, servers, networking, and virtualization—while leaving the setup and management to the business.
Why choose IaaS?
A company might opt for IaaS if it needs flexibility and control over its infrastructure. It's ideal for businesses with an IT team capable of managing configurations and updates but that want to avoid the hassle or cost of maintaining physical hardware. For example, an e-commerce company with fluctuating website traffic might choose IaaS to scale its infrastructure during busy seasons and cut back during slower times.
Platform as a service (PaaS)
PaaS takes things a step further by including everything IaaS offers, plus the operating system, middleware (software that connects applications), and runtime (the environment where applications run). This creates a complete, ready-to-use platform where businesses can develop, deploy, and manage applications without having to deal with the complexities of managing the underlying infrastructure themselves.
Why choose PaaS?
PaaS is perfect for businesses that focus on development but don't want to spend time managing hardware and operating systems. Companies like software development firms often choose PaaS because it allows developers to concentrate on coding and deploying apps without worrying about the underlying infrastructure. For example, a mobile app developer might use PaaS to accelerate app creation and testing without building a backend environment from scratch.
Software as a service (SaaS)
SaaS is the simplest option. Everything—servers, apps, and updates—is managed for you. You log in and use the software you need, like email, project management tools, or photo editing programs.
Why choose SaaS?
SaaS is often the best choice for companies looking for simplicity and convenience. Businesses that don't have an IT team or want to avoid managing software updates and maintenance will often choose SaaS. For instance, a small marketing agency might use SaaS tools like Google Workspace or Trello to manage projects, communicate, and store files without the need for technical expertise or support.
Expanding the cloud: Specialized services and key concepts
Cloud computing has evolved beyond its foundational models, introducing specialized services and innovative concepts that cater to diverse business needs.
Here’s a closer look:
Disaster recovery as a service (DRaaS) and backup as a service (BaaS)
These services provide cloud-based solutions to replicate on-premise enterprise data centers and systems. In a disaster or data loss, businesses can quickly restore operations by spinning up their systems in the cloud. DRaaS and BaaS are cost-effective alternatives to traditional colocation data centers, ensuring business continuity without the overhead of managing physical infrastructure.
Serverless computing
Serverless computing is a powerful cloud model where the provider manages backend infrastructure, allowing developers to focus solely on code and logic. It runs code blocks on a per-request basis, scaling seamlessly with demand.
Functions as a service (FaaS)
In response to triggers like database updates or API calls, the required servers, operating systems, and tools are provisioned automatically and shut down after the function is complete, ensuring efficiency and cost savings.
These specialized services and advanced cloud concepts illustrate how the cloud continues to expand its reach, offering more tailored and efficient solutions for modern business challenges.
How cloud computing works: Three essential layers
Cloud computing relies on three layers of technology that blend seamlessly, each playing a unique role.
Here’s how they fit together:
- Architecture is the blueprint. It sets up all the components—like networks, servers, and software—to connect and interact to deliver services over the Internet.
- Infrastructure is the backbone. It combines physical hardware (like data centers) and virtual tools to store data, run apps, and power business needs.
- Platforms are user-friendly tools like AWS or Google Cloud that sit on top of the technology so businesses can build, host, and manage their systems.
Together, these layers ensure that cloud computing delivers the speed, dependability, and adaptability businesses rely on today. Let’s take a closer look at each one.
Architecture: The blueprint
Think of cloud architecture like the plumbing in a house. It connects the water supply (servers and storage) to the faucets (your apps and devices) so you can get what you need when you need it. Like good plumbing, it’s built to handle demand and keep everything flowing without interruption.
Cloud architecture keeps everything running smoothly, but what makes it so effective? Let’s break down some of its key features and how they ensure the cloud stays fast, reliable, and flexible for businesses and users alike.
Broad network access
A big part of cloud computing architecture is broad network access, which lets users connect to the cloud anywhere with an Internet connection. Whether you’re using a computer at work, a tablet at home, or a phone on the go, you can access your data and apps anytime. This accessibility is made possible by advanced networking protocols and high-speed infrastructure, ensuring a smooth experience for users wherever they are.
Resource pooling
Resource pooling lets cloud providers share physical resources like servers, storage, and networks among multiple users. Using technologies like virtualization, physical servers are divided into virtual ones, ensuring each user gets a private and secure space within the shared system. This setup is highly efficient because resources can be dynamically allocated to meet demand, making it easy for the cloud service to scale and handle the needs of different businesses.
On-demand self-service
On-demand self-service means users can access resources like storage, servers, or applications anytime without going through IT teams or waiting for approvals. It’s like having a self-serve station where you can grab what you need right when needed.
Measured service
Measured service ensures that you only pay for what you use. It tracks your usage in real-time—the amount of storage, computing power, or bandwidth—and provides detailed, transparent reports similar to a utility bill.
Infrastructure: The backbone
Infrastructure is the foundation of cloud computing, offering a mix of physical and virtual systems that work together to power data storage, run applications, and handle processing needs seamlessly. Below are the key components of cloud computing infrastructure.
Physical data centers
Even though we call it the "cloud," all that data and computing power has to live somewhere. That "somewhere" is massive, secure facilities called data centers. These buildings house the servers and other hardware that keep the various cloud services running. They’re equipped with backup power, temperature control, and tight security to ensure the systems operate smoothly 24/7, no matter what’s happening outside.
Cloud servers
Cloud servers are the machines inside data centers that handle the heavy lifting of cloud computing. They are responsible for storing data, running applications, and processing workloads. In many cases, a single physical cloud server can be split into many virtual servers with virtualization technology, providing the most value for the cloud provider. These machines are the backbone of cloud services, delivering the computing power and storage that businesses and users rely on every day.
Virtualization
Virtualization uses hypervisor software to divide a single physical server into multiple independent virtual servers. A hypervisor is a specialized program that acts as a manager, allocating resources like computing power, storage, and memory to each virtual server. Each virtual server operates as if it were its own physical machine, complete with its own operating system and resources. This setup allows cloud providers to get the most out of their hardware, enabling multiple businesses to share the same physical server while ensuring that their data and applications remain isolated, secure, and completely independent from one another.
Networking
Networking is what connects all the pieces of the cloud—servers, storage, and users—so they can communicate smoothly. It uses fast connections, like fiber-optic cables, to make sure data moves quickly and reliably. Networking allows you to access your cloud resources from anywhere, whether you’re at home, in the office, or halfway across the world.
Redundancy and backup systems
Redundancy and data backup systems are what make the cloud so dependable. Redundancy means extra servers are ready to jump in if something breaks, so everything keeps running without a hitch. Backups are secure copies of your data, often stored in different locations, so they'll be available if anything goes wrong. Together, they ensure your business keeps moving, even if there's a hardware issue or an unexpected outage.
Platform: The tools
Platforms make cloud services accessible. They sit on top of the behind-the-scenes infrastructure and give businesses the tools they need to run their systems. Whether hosting a website, storing data, or analyzing information, platforms like AWS, Google Cloud, and Microsoft Azure make it easy to use.
Application hosting
Using the architecture’s connectivity and the cloud infrastructure’s servers and storage, platforms take over backend tasks like provisioning, scaling, and monitoring, making it easy for businesses to deploy and run websites, apps, or tools.
Scalable storage
Platforms make storage easy to manage. Need more room? Add it instantly. Don’t need as much? Scale back. It’s a smart, budget-friendly way to handle data growth and keep costs under control.
Development tools
Platforms come with ready-to-use tools that make it easier to create and launch applications. For example, AWS has tools for running code without managing servers, and Google Cloud offers services to deploy apps quickly.
Analytics and machine learning
Platforms also provide advanced features, like analyzing data or building AI models. Businesses can dive into their data to spot trends with big data analytics or use machine learning tools to make smarter decisions—all without needing specialized equipment.
Global reach
Platforms are set up around the world, so businesses can deliver their services closer to their users. This means faster load times and better performance on client devices, no matter where customers are.
Migrating to the cloud: Assess your current infrastructure
Moving from an onsite system to the cloud is a big step, and it begins with understanding your existing infrastructure and how it fits into a cloud-based model. Start by examining your current system to see what's ready for the transition and what may need adjustments or upgrades.
Inventory your applications
Make a detailed list of all your applications, databases, and systems. Identify which are critical to your business operations and which are outdated or redundant.
Evaluate compatibility
Determine if your applications are cloud-ready. Some modern cloud systems can move quickly, but older legacy applications may require updates or a complete redesign to function correctly in a cloud environment.
Assess data storage needs
When preparing to move your business to the cloud, it's important to closely inspect the data your business handles and how it's currently stored. Different kinds of data may require different cloud storage solutions, so knowing what you have helps you make the right choice.
Here are the types of data you’ll want to identify and consider when choosing the best cloud storage solution for your business:
Structured data: This is information stored in organized formats, like rows and columns in relational databases (e.g., customer records or sales data). Structured data transitions easily to cloud database services, making it simple to manage and query.
Unstructured data: These are files like images, videos, emails, and documents that don’t fit into a traditional database format. Cloud storage solutions optimized for unstructured data are designed to efficiently handle large, flexible file types.
Semi-structured data: This data falls between structured and unstructured formats. Examples include JSON files and XML, which have some organizational structure but don’t fit into a standard database. Hybrid storage solutions are often ideal for managing semi-structured data.
Archived data: This includes older data that needs to be kept for compliance purposes or future reference. Cloud solutions, such as cold storage, are specifically designed for reliable and secure long-term retention.
Real-time data: This includes continuously streaming information, such as live IoT sensor data or real-time analytics. High-speed storage and processing solutions are necessary to handle this type of data effectively.
Each type of data has its own requirements and ideal cloud storage solutions. Understanding what your business manages will help you make informed decisions during the cloud migration process.
