Cloud computing services are used by many businesses of all sizes to optimise their computing and data storage capabilities, allowing them to focus on core operations.

Even though cloud services have been around for quite some time, there’s still a lot of confusion regarding what cloud computing means, why companies are interested in adopting cloud computing solutions and services, which services are offered by cloud computing solution providers, etc.

In this article, we’ll discuss some basic information about the most popular cloud computing solutions and services offered by companies like Microsoft and Amazon, how they can be beneficial to your business, etc.

The 4 Main Areas of Cloud Computing

For starters, there are three main areas of cloud computing that everyone needs to be aware of. 

They are as follows: 

• Managed Cloud (Platforms-as-a-Service), 
• Software as a Service (SaaS)
• Infrastructure as a Service (IaaS).
• Network as a Service (NaaS) 

Businesses need to understand how each of these three areas works so they can make better decisions about what service is right for them. First, let’s take a look at Platforms-as-a-Service. If you’re operating in an industry that requires you to build custom applications or programs, then PaaS may be just what you need.

Cloud Services

Cloud computing allows users to store, process, and retrieve data from different computers with an internet connection. 

There are four categories of cloud services- 

1. Cloud infrastructure as a service (IaaS)
2. Cloud platform as a service (PaaS) 
3. Software as a service (SaaS) 
4. Network as a service (NaaS). 

Cloud IaaS 

Cloud IaaS is designed for enterprises that need server space, storage space, or virtual machines on which they can host their data. There are also three main providers of IaaS – Amazon Web Services, Microsoft Azure, and Google Cloud Platform.

Cloud PaaS

Cloud PaaS is made for developers who want to create applications without having to worry about servers or programming languages. The most popular PaaS provider is Heroku. 

Cloud SaaS

Cloud SaaS provides companies with access to applications hosted by third parties in return for regular payments. The model works well for companies that want all employees to have access to business applications but don’t want them using personal devices such as smartphones and tablets.

The most common SaaS application is email but there are many others including Salesforce, DocuSign, Slack, and Dropbox Business.

Cloud NaaS

Cloud NaaS offers businesses unlimited bandwidth at an affordable price so they can focus on growing their business rather than managing networks.

Two Major Benefits of Cloud Computing 

Cloud computing has become increasingly popular, especially with SMBs. There are two different ways you can move your business’s data into a cloud service.

1- Cloud Storage

The first option is to store your data in cloud storage. Cloud storage services, like DropBox or Google Drive, work by giving you access to an online hard drive; they also allow you to sync multiple devices so that files on one device are accessible on all others.

Cloud storage services are great for simple backup purposes or for making smaller amounts of data available across devices—but they don’t provide any extra processing power.

Cloud computing is a system in which users can use software over an Internet connection instead of having to buy and install programs on individual computers. 

2- Additional Processing Power

If you want additional processing power beyond what your desktop can handle, then cloud computing is likely a better choice for your business.

With cloud computing, you rent out virtual space from another company; while it might seem counterintuitive to pay someone else to do something that your computer could do for free. 

There are some real benefits when it comes to paying a third party. Businesses can save money by using cloud services because they don’t have to pay for their hardware, installations, or maintenance costs.

Namely, paying someone else allows you access to a much larger pool of resources than your machine could ever offer.

In other words, if you have specific needs or demands (like needing additional server space), renting out resources from another company can be much more cost-effective than purchasing them yourself.

Top 10 Common Uses of Cloud Computing

Companies of all types, sizes and industries use the cloud for a variety of use cases including:

1. Infrastructure-as-a-Service (IaaS) and Platform-as-a-Service (PaaS)
2. Hybrid cloud and multicloud.
3. Testing and development.
4. Big data analytics.
5. Cloud storage.
6. Disaster recovery.
7. Data backup.
8. Virtual desktops
9. Customer facing web applications
10. Email

Which Services Do Businesses Use Today?

According to a survey of businesses by Spiceworks, cloud services are used across industries in various combinations. The majority of companies surveyed were found to use three or more cloud service types in their business. 

Most businesses (82 percent) were using at least one type of cloud application services like Salesforce or Office 365; 83 percent were using at least one type of infrastructure-as-a-service, like Amazon Web Services; and 84 percent were using at least one business process-as-service for things like payroll or HR management systems.

How Can I Avail Cloud Services?

If you’re looking for cloud computing services, there are a few things you should know. Many cloud services can be accessed remotely; many different companies have already made the switch from standard computing to cloud-based solutions.

If you’re still not convinced that switching is right for your business, here are some of our best reasons to leave your old methods in favour of cloud services.

Cloud Computing has greater reliability. Cloud servers aren’t at risk of being affected by software issues or viruses—the data is stored on remote servers and isn’t affected by internal hardware failures.

Cloud Computing Statistics 2026

Cloud computing has become essential business infrastructure, supporting artificial intelligence, data storage, cybersecurity, remote work and enterprise applications.

The market continues to expand rapidly as organisations move more workloads online and invest in the computing power required for generative and agentic AI.

1. Market Size and Growth

Global enterprise spending on cloud infrastructure services reached approximately US$128.6 billion during the first quarter of 2026, an increase of 35% from the same period in 2025.

Trailing 12-month revenue reached US$455 billion, while the market’s annualised revenue run rate exceeded US$500 billion for the first time. Public infrastructure-as-a-service and platform-as-a-service recorded combined growth of 38% during the quarter.

In Australia, organisations are forecast to spend A$33.62 billion on public cloud services in 2026, up 17.9% from A$28.51 billion in 2025.

2. Data Storage and Cloud Workloads

Cloud data warehouses are now used by 71% of organisations, making them the most widely adopted public cloud service measured in Flexera’s 2026 State of the Cloud Report.

Relational database-as-a-service platforms are used by 64%, followed by generative AI cloud services at 58% and container services at 56%. These figures reflect the shift from using the cloud primarily for storage towards running databases, analytics, AI models and business-critical applications.

Public cloud workloads among small and medium-sized businesses increased from 55% to 63% over the year, indicating that smaller organisations are also moving a greater share of their applications and data into cloud environments.

3. Cloud Infrastructure Revenue

Cloud infrastructure providers generated almost US$129 billion in revenue during the first three months of 2026, more than US$35 billion above the corresponding quarter in 2025.

Amazon Web Services retained the largest share of the worldwide cloud infrastructure market at 28%, followed by Microsoft at 21% and Google at 14%. Together, the three hyperscalers controlled 63% of the overall market and approximately 67% of the public IaaS and PaaS market.

4. Adoption and Usage

Hybrid cloud remains the dominant enterprise model, with 73% of organisations combining public and private cloud environments in 2026.

Multi-cloud adoption also increased by two percentage points, although many organisations inherited multiple cloud platforms through acquisitions, decentralised purchasing or separate development teams.

Among large enterprises, 76% now spend more than US$5 million each month on public cloud services. Governance has also become more formal, with 71% of organisations operating a Cloud Centre of Excellence or equivalent function and 63% using a dedicated FinOps team to manage cloud spending.

Every organisation surveyed by Flexera reported using generative AI in some capacity, while 45% said they used it extensively. Use of public cloud generative AI services increased to 58%, up from 50% a year earlier.

5. Energy Consumption

Cloud and AI growth is placing greater pressure on electricity networks and data centre infrastructure.

The International Energy Agency reported in April 2026 that global data centre electricity demand increased by 17% during 2025, compared with overall global electricity demand growth of 3%.

The IEA’s updated 2026 analysis estimates that data centres consumed approximately 485 terawatt-hours of electricity in 2025.

Consumption is projected to almost double to 950 terawatt-hours by 2030, equivalent to about 3% of worldwide electricity demand. Electricity use by AI-focused data centres is expected to triple over that period.

6. Public Cloud Spending Breakdown

Software-as-a-service remains the largest category of Australian public cloud spending in 2026, although infrastructure and platform services are growing more quickly.

Australian public cloud spending in 2026 is forecast to include:

• SaaS: A$16.38 billion, up 13.8%
• PaaS: A$10 billion, up 20.9%
• IaaS: A$7.09 billion, up 24.1%
• Desktop-as-a-service: A$155 million, up 9.7%
• Total public cloud spending: A$33.62 billion, up 17.9%

The faster growth of IaaS and PaaS reflects rising demand for AI computing capacity, application modernisation, data processing and platforms capable of managing autonomous workflows.

7. Cloud Security, Governance and Cost Management

As cloud estates become larger, security, compliance and unpredictable costs are emerging as major business concerns.

Security and compliance risks were identified as the leading challenge for cloud-based AI projects by 53% of organisations, while 40% cited data quality and 30% identified unpredictable AI costs as significant obstacles.

Cloud performance is also being measured differently. In 2026, 64% of organisations said the value delivered to business units was their leading measure of cloud success, up 12 percentage points from the previous year. A further 49% use unit economics to connect cloud expenditure with business results.

Top 5 Advantages Of Cloud Computing

1. Scalability and Performance

Cloud technology can be scaled to meet changing IT needs of businesses. It is common for a company to need more storage space and bandwidth to handle increasing website traffic. Cloud servers can be automatically deployed to allow businesses to scale up or down, and provide optimal performance for heavy loads. Cloud technology can also increase website speed and minimise downtime.

2. Business Continuity

Businesses can invest in cloud computing to ensure reliable disaster recovery and backup solutions. Complex disaster recovery plans can prove costly for many businesses. It is also time-consuming to back up data. 

The cloud is designed so that all data in it is mirrored across multiple servers. This ensures that even if one server fails, other data can be backed up immediately. Website downtime is minimized and productivity lost due to inability to quickly access data after a failure.

3. Improved Collaboration

Collaboration between communities and groups that have the same files has been proven to be significantly improved in the cloud environment. It eliminates communication barriers that traditional IT models create.

All of this makes it easier for employees to collaborate with key personnel and quickly access information from different locations. This streamlines processes, which allows for more work to be done in a shorter time.

4. Cost Efficiency

Many would say the greatest benefit of cloud computing is its IT operational cost savings. Remote servers eliminate the need to store data and applications in-house. There are also no overhead costs like software updates, management, and data storage. 

Cloud-based services can be rented on a per-use basis. This allows businesses to rent exactly what they require and guarantees a return on their investment. Cloud computing is becoming increasingly popular with small and medium-sized companies that have limited budgets.

5. Flexibility

Companies who use cloud-based services have a lot of flexibility. Cloud servers can be accessed remotely and offer unlimited bandwidth and storage space. This allows companies to scale up or down their capacity to meet increased website traffic.

Cloud computing eliminates the need for equipment upgrades and purchase on-site. Employees can also access data and applications on a remote server, from anywhere, at any time.

Why Is The Cloud Growing So Quickly?

The idea of cloud computing has been around for decades, but it wasn’t until 2006 that Amazon Web Services (AWS) became commercially available. It didn’t take long for AWS to become a popular cloud solution provider—today, AWS is one of three major players in public cloud solutions. 

There are many reasons why Amazon was able to grow so quickly, but there are also many reasons why other providers were able to catch up so fast—the early bird may have gotten the worm, but anyone can grab an apple from a tree.

The top three reasons people flock to public cloud solutions are cost-effectiveness, access to services they wouldn’t be able to access otherwise, and ease of use.
