What is Cloud Computing? A Comprehensive Guide

What is cloud computing?

Cloud computing is no longer just a trend — it’s the new standard. Companies across all industries are leveraging the cloud to increase agility, accelerate innovation, and drive operational efficiency. In essence, cloud computing refers to the delivery of computing resources — such as storage, databases, networking, software, and analytics — over the internet, rather than through local servers or personal devices. This eliminates the need for businesses to own and maintain physical infrastructure, providing access to scalable, on-demand resources provided by third-party vendors.

 Through digital transformation, organizations are unlocking their potential, allowing them to scale and adapt quickly to an ever-changing environment.

But it’s not just about adopting technology; it’s about leveraging cloud computing strategically to stay competitive, enhance customer experience, and boost company valuation.

Key features of cloud computing

What makes cloud computing such a game-changer? It all comes down to a few key features that unlock flexibility, scalability, and efficiency — the very reasons why so many businesses are making the switch.

• On-demand self-service: With cloud computing, businesses can instantly access and adjust resources like storage or servers, without waiting for manual setup by the provider.
   
• Broad network access: Cloud platforms allow teams to access resources from anywhere, enhancing collaboration and productivity.
   
• Resource pooling: Infrastructure is shared across multiple clients, optimizing usage and reducing costs.
   
• Rapid elasticity: The ability to scale up or down instantly ensures businesses can handle spikes in demand without issues.
   
• Measured service: Cloud allows a pay-as-you-go model, reducing operational costs.

These features create a flexible, scalable environment that enables organizations to operate more efficiently, innovate faster, and focus resources on strategic initiatives rather than infrastructure management.

Benefits for businesses and development teams

Cloud computing creates value at every level of an organization — from enabling strategic business growth to simplifying everyday work for development teams. By shifting to the cloud, businesses can achieve cost efficiency, faster innovation cycles, and improved collaboration.

For example, when collaborating with VAS — a global leader in connected farm management systems serving over 10 million cows daily across thousands of dairies — we worked closely to design a tailored cloud solution that enabled them to scale operations seamlessly during peak demand periods. Unlike their previous physical infrastructure, which struggled with system outages, the cloud-based approach we implemented ensured consistent performance. We also introduced dynamic resource allocation, which not only increased operational efficiency but also laid the foundation for their sustained growth. Throughout the entire process, Making Sense was a strategic partner, providing hands-on support to ensure the solution aligned perfectly with VAS's evolving business needs.

Here are just a few ways cloud computing can drive value for businesses:

• Cost efficiency: By reducing or eliminating the need for upfront hardware investments and ongoing maintenance, cloud computing transforms capital expenses into predictable operational costs.
   
• Speed and agility: With cloud platforms, teams can access new environments, tools, and infrastructure in minutes rather than weeks — accelerating time-to-market and fostering experimentation.
   
• Scalability: Cloud computing allows businesses to scale resources up or down based on demand, without compromising performance.
   
• Enhanced collaboration: Cloud-based tools enable distributed teams to collaborate in real time, improving productivity and reducing silos.
   
• Improved security: Leading cloud providers invest heavily in security, offering protections like encryption, identity management, and compliance certifications that often exceed on-premises capabilities.
   
• Business continuity: Built-in redundancy and disaster recovery options help ensure high availability and minimize downtime.

For development teams, cloud computing unlocks faster prototyping, more efficient testing environments, and seamless integration with DevOps practices — all of which accelerate innovation cycles and improve product quality.

Service models: IaaS, PaaS and SaaS

Understanding the different service models within cloud computing is key to selecting the right solution for your business needs. Each model offers a distinct level of control, flexibility, and responsibility.

Infrastructure as a Service (IaaS)

IaaS provides virtualized computing resources over the internet. Businesses rent servers, storage, and networking components, while maintaining control over operating systems and applications.

Use case: Companies that want maximum flexibility to configure their environments but avoid hardware management.

Platform as a Service (PaaS)

PaaS offers a ready-to-use platform where businesses can develop, run, and manage applications without dealing with the complexity of building and maintaining infrastructure.

Use case: Development teams focused on rapid application development and deployment.

Software as a Service (SaaS)

SaaS delivers software applications over the internet on a subscription basis. Providers handle everything — infrastructure, updates, security, and availability.

Use case: End-users accessing business applications like CRM, ERP, or productivity tools directly from the cloud.

Deployment types: public, private and hybrid cloud

Choosing the right cloud deployment model is a strategic decision that depends on business goals, regulatory requirements, and technical needs. Let’s explore the three primary models and their typical use cases:

Public cloud

In the public cloud, services are delivered over the internet and shared across multiple customers. Providers like AWS, Microsoft Azure, and Google Cloud offer vast scalability and cost efficiency. However, since resources are shared, businesses need to carefully manage data privacy and compliance risks.

Best for: Startups, growing businesses, or companies with variable workloads that prioritize flexibility and cost-effectiveness.

Private cloud

A private cloud is dedicated to a single organization, either hosted on-premises or by a third-party provider. It offers greater control, customization, and security. However, infrastructure management falls entirely on the organization, making security, scalability, and performance dependent on internal expertise and budget.

Best for: Regulated industries, businesses with sensitive data, or organizations requiring high levels of customization.

Hybrid cloud

A hybrid cloud blends public and private cloud environments, enabling data and applications to move between them. This model provides flexibility, scalability, and control. However, managing a hybrid setup can increase complexity — requiring strong integration, clear governance, and skilled teams to avoid security gaps or performance issues.

Best for: Companies seeking to balance regulatory compliance with the scalability of the public cloud or managing legacy systems alongside modern applications.

Each deployment model comes with trade-offs. The optimal choice often depends on how much control you need versus how much scalability and cost savings you want to unlock.

Cloud computing myths: What’s fact vs. fiction?

Despite its widespread adoption, cloud computing still carries misconceptions that can delay or derail strategic initiatives. Let’s address some of the most common myths circulating in boardrooms:

Myth #1: The cloud isn’t secure

→ The reality: Cloud providers have turned security into a competitive advantage. They invest millions of dollars annually in advanced security frameworks, data encryption, continuous monitoring, and compliance certifications.

While security will always be a shared responsibility between the provider and the customer, assuming that on-premises infrastructure is automatically more secure is no longer accurate. In fact, many security breaches today occur due to internal misconfigurations — not because of flaws in cloud technology.

For example, a misconfigured cloud setting could accidentally expose sensitive data, even though the cloud provider has implemented robust security measures. This highlights the importance of proper cloud configuration and governance, especially in public cloud environments, where resources are shared among multiple clients.

When it comes to public cloud, one of the risks is that multiple organizations may share the same infrastructure. However, proper configuration and careful management of security settings can prevent these shared resources from becoming a vulnerability. This is why businesses must focus on internal processes, such as configuring cloud services correctly and adhering to best practices in access control, to minimize the risk of breaches.

Myth #2: The cloud isn’t reliable

→ The reality: Leading cloud providers operate under strict Service Level Agreements (SLAs), often guaranteeing 99.9% uptime or higher. They have global infrastructure, redundancy protocols, and real-time monitoring that allow them to detect and resolve issues faster than most in-house teams.

While no technology is immune to downtime, cloud-based solutions typically offer greater resilience, scalability, and faster disaster recovery capabilities than legacy systems.

Myth #3: The cloud is all-or-nothing

→ The reality: Cloud adoption is not a binary decision. Organizations don’t have to migrate everything overnight. In fact, hybrid and multi-cloud strategies have become the standard approach for many companies, allowing them to move critical workloads gradually, maintain certain assets on-premises, or leverage different providers for different needs.

This flexibility empowers businesses to balance innovation with risk management and to scale their cloud journey at their own pace.

Myth #4: Once in the cloud, you can’t leave

→ The reality: Cloud doesn’t have to mean vendor lock-in. With the right architecture — leveraging containerization, APIs, and multi-cloud strategies — companies can build portability and flexibility into their infrastructure from the very beginning.

This enables organizations to avoid dependency on a single provider and maintain control over their technology roadmap.

Myth #5: Cloud adoption = Automatic innovation

→ The reality: Cloud platforms provide powerful tools and capabilities — but true innovation still depends on people, culture, and processes. Simply migrating to the cloud won’t drive transformation unless it’s supported by a clear strategy, agile methodologies, and the right talent to unlock its full potential. Cloud is an enabler, not a magic wand.

We don’t just help organizations migrate to the cloud — we guide them through the process, ensuring that their cloud solutions align with their goals, enhance operational efficiency, and enable long-term growth as part of a wider change that drives real results.

Myth #6: Cloud is just for tech companies

→ The reality: Cloud computing is transforming industries far beyond the tech sector. From manufacturing and retail to healthcare and financial services, businesses of all types are leveraging cloud solutions to drive operational efficiency, improve customer experience, and accelerate time-to-market.

In today’s digital economy, cloud capabilities are essential for any organization looking to stay competitive — regardless of industry.

How to choose the right cloud solution

Choosing the right cloud solution can feel overwhelming, right? With so many options out there, finding the one that fits your business needs can feel like a gamble. That's why, when guiding our clients toward the right cloud solution, these are the factors we always take into account:

1. Business Goals

When choosing the right cloud model, understanding your business goals is crucial. Whether you're focusing on innovation, improving operational efficiency, reducing costs, or scaling your operations, your cloud strategy must align with those priorities. For example, if cost reduction is a primary goal, you might lean toward a cloud model that optimizes resource usage and offers pay-as-you-go pricing. If innovation is your focus, then a flexible, scalable platform with rapid deployment options might be more suitable.

2. Compliance and Security Requirements

Different industries face different regulations regarding data security, privacy, and compliance. If your company operates in a highly regulated sector, such as finance or healthcare, compliance with these regulations will be a key factor in choosing the right cloud solution. This could influence whether you opt for a private cloud for more control over security or a public cloud solution that offers built-in security features and certifications.

3. Workload Characteristics

When considering a cloud solution, it’s important to assess the characteristics of your current applications and workloads. Some of your applications might already be designed to work in the cloud, meaning they can be moved with minimal changes. Others might need to be re-architected or adjusted to operate effectively in a cloud environment. For example, legacy systems may be better suited for private clouds due to security or compliance needs, while more modern applications may thrive in a public cloud environment due to their scalability and flexibility.

4. Budget and Cost Optimization

Balance short-term budget constraints with long-term operational savings. Cloud cost models vary widely depending on usage and provider.

5. Internal Capabilities

Not all cloud models are equally complex. Some models, such as Infrastructure as a Service (IaaS), require more technical expertise to manage servers, storage, and networking components, while others, like Software as a Service (SaaS), are more straightforward because the provider manages most of the technical aspects. It’s essential to evaluate your team’s capabilities and readiness for managing the complexity of your chosen cloud model. For instance, if your internal team lacks cloud expertise, you may want to opt for a Platform as a Service (PaaS) or SaaS model, where the cloud provider takes on more of the management tasks.
