• Take advantage of cloud computing's flexibility to work from anywhere with any internet-connected device, allowing you and your team to access the same data simultaneously whether you're at home, on-site, or travelling.

What is cloud computing?

Cloud computing is the delivery of computing services over the internet, including storage, software, and processing power. Instead of keeping files and applications on your computer, you access them online from any device, anywhere, at any time.

This means you don't need to buy, own, or maintain physical servers or data centres. You simply pay for what you use, when you use it.

How does cloud computing work?

Cloud computing works by storing your data and running your software on remote servers instead of your local computer. When you access a cloud service, your device connects to these servers through the internet.

It's like streaming music. You don't download every song to your phone. Instead, the music lives on Spotify's servers and streams to your device when you press play. Cloud computing works the same way with your business data and applications.

Here's what happens when you use cloud software:

1. You log in through your web browser or app
2. Your request travels over the internet to the provider's data centre
3. The cloud servers process your request and send the results back
4. You see and interact with your data on screen

All the heavy lifting happens on powerful remote servers. Your device simply displays the results. This is why you can access the same information from your laptop, tablet, or phone.

Many everyday services use cloud computing. Everyday examples include:

• Internet banking: Access your financial data online from anywhere
• Web-based email: Send and receive messages from any device
• Cloud storage: Store files online and access them from anywhere
• Online shopping: Let customers browse and buy 24/7
• Cloud accounting software: Keep your financial data online so you, your team, and your accountant can access it simultaneously from any location

Benefits of cloud computing for small business

Cloud computing gives small businesses access to enterprise-level technology at affordable prices and with simple setup. Benefits for your business include:

• Work from anywhere: Access your data from any device with an internet connection, whether you're at home, on-site, or travelling
• Automatic backups: Your data is continuously saved and protected automatically
• Built-in security: Professional-grade protection handles threats for you
• Automatic maintenance: Updates, patches, and upgrades happen automatically in the background
• Real-time collaboration: Multiple team members and your accountant can work on the same data simultaneously
• Predictable costs: Pay a regular subscription instead of large upfront investments in hardware and software
• Scalability: Add users or features as your business grows using your existing equipment

Types of cloud computing

Understanding the different types of cloud computing helps you identify which approach fits your business needs. Cloud services are categorised by how they're deployed and what they provide.

Cloud deployment models

Cloud services can be delivered in three main ways:

• Public cloud: Public cloud services are owned and operated by third-party providers and delivered over the internet. You share the underlying infrastructure with other users, but your data remains private and secure. Most small businesses use public cloud services like Xero, Google Workspace, or Microsoft 365.
• Private cloud: Private cloud infrastructure is dedicated to a single organisation. It offers more control but requires significant investment and technical expertise. This model suits larger enterprises with strict compliance requirements.
• Hybrid cloud: Hybrid cloud combines public and private cloud elements. Some data stays on private servers while other applications run in the public cloud. This approach offers flexibility but adds complexity.

Cloud service models

Cloud services also differ in what they provide.

• SaaS (Software as a Service): Ready-to-use applications you access through your browser. Examples include accounting software, email, CRM, and project management tools. This is the most common type for small businesses.
• PaaS (Platform as a Service): Development platforms for building custom applications. Primarily used by software developers.
• IaaS (Infrastructure as a Service): Virtual computing resources like servers and storage. Typically used by IT teams managing complex systems.

For most small businesses, SaaS applications provide everything you need with simple setup.

Who uses cloud computing?

Cloud computing is now mainstream, with an estimated using cloud services to some extent across every industry and business size. From sole traders to global enterprises, businesses rely on cloud services daily. Small businesses increasingly use cloud tools to compete with larger companies while keeping IT costs low.

Different industries use cloud computing in various ways:

• Professional services: Manage client files, track time, and collaborate remotely
• Construction: Access plans and documentation on-site, track costs in real time, and coordinate with subcontractors
• Retail: Manage inventory, process payments, and track sales across multiple locations from a single dashboard
• Healthcare: Store patient records securely, manage appointments, and handle billing digitally
• Education: Deliver courses online, track student progress, and manage enrolments remotely

The shift to cloud computing isn't limited to tech-savvy businesses. It's become the standard way of working for organisations that want flexibility, security, and lower IT costs.

Cloud myths

Common concerns about cloud computing often stem from misconceptions. The facts:

Is cloud computing the same as the internet?

They're different. The internet is the connection you use to reach the cloud. The cloud itself is where your data and applications are stored and processed on remote servers.

Is my data safe in the cloud?

With threats like ransomware attacks having increased by 35% in a single year, your data is typically safer in the cloud than on your computer. Cloud providers invest millions in security systems, automatic backups, and expert teams to protect your information. Cloud data remains secure even if your device is compromised.

Is the cloud an Apple product?

Apple has a product called iCloud which uses cloud technology, but many other companies provide products in the cloud such as Google, Dropbox and Xero.

How does cloud computing handle internet outages?

Internet outages are rare and usually brief. When connectivity returns, your data is exactly where you left it. Many cloud applications also offer offline modes for essential tasks.

Is cloud computing here to stay?

The cloud has been around for years and it's only getting bigger. Internet banking started over 15 years ago. Now the technology is so fast and cheap that it's being used for everything.

How much does cloud computing cost?

Cloud computing is often more affordable than traditional IT. You pay only for what you use, with flexible pricing and automatic upgrades included.

Do I keep control of my data?

You gain control. Access your data from any device, share it with specific people, and revoke access instantly. You decide who sees what and when.

Can anyone use cloud computing?

Cloud tools are designed to be simple. You log in and start working. Everything is handled automatically.

Making the move to cloud computing

Moving to cloud computing is simple. Getting started requires minimal technical knowledge and a modest budget.

Many businesses begin with a single cloud application, like accounting software, and expand from there. The benefits compound as you connect more tools: your data flows automatically, your team collaborates seamlessly, and you spend less time on admin.

Cloud-based accounting is often the first step. It gives you real-time visibility into your finances, automates routine tasks like bank reconciliation, and lets you collaborate directly with your accountant.
