Understanding Cloud Services: What They Are and Why They Matter

A vast majority of UK and global businesses now make use of cloud services. Cloud computing has become fundamental to UK business operations, supporting everything from remote work and secure data storage to advanced analytics. 

But what is cloud services exactly, and how does the technology work? Even more importantly, why should your organisation make the switch to a cloud-powered system? Find out everything you need to know to understand cloud services here in this handy guide.

What Are Cloud Services?

Cloud services are on-demand IT resources delivered over the internet instead of being hosted on local services. These resources may include servers, storage, software and networking. 

For businesses, all that is required to get started is a secure and fast internet connection. There’s no need to buy hardware or install software on individual devices. 

You’re likely to have encountered cloud services in day-to-day life, whether it’s at work or in your personal life. Some of the most widely used examples include cloud email platforms such as Microsoft 365, along with online file storage and backup provided by the likes of Google Drive. In the workplace, there are also a large number of different web-based business applications. 

How Cloud Services Work

Providers of cloud services operate large-scale data centres. This is where the physical infrastructure is located, which includes servers, storage systems and networking equipment.

By making use of virtualisation technology, providers are able to split one set of physical hardware into multiple virtual systems. This allows different customers to use the same resources without accessing each other’s data. Each customer gets their own secure, separate environment. 

Here’s how it works in simpler terms:

1. You (the user) accesses a cloud service via the internet
2. The cloud platform delivers the required computing resources instantly
3. Data and applications are processed, run and stored remotely, rather than on the user’s device. 

Most cloud computing services also include something known as ‘built-in redundancy’. This means that data is replicated across multiple locations, with the aim of improving performance, resilience and disaster recovery compared to traditional on-site systems.

Types of Cloud Services

The market for cloud-based tools and applications is growing all the time, and there are now hundreds if not thousands of options for modern businesses to choose from. 

But what are some of the most common cloud services? Some of the most widely used services can be broadly categorised as follows:

Infrastructure as a Service (IaaS)

This provides the company with virtual servers, storage and networking. The business controls operating systems and applications, but without needing to manage physical hardware.

 

Platform as a Service (PaaS)

This offers a ready-made platform for developing and running applications, without worrying about servers or system maintenance.

 

Software as a Service (SaaS)

SaaS is fully managed software accessed via a browser. This is the most common cloud model for everyday business tools, such as email, accounting software, CRM systems and collaboration tools to name just a few.

Common Uses of Cloud Services

So, what are examples of cloud services commonly used in business? Some of the most widespread applications include:

• Data storage and backup – this provides businesses with secure, off-site storage of files and data, with the benefit of high (if not unlimited) storage capacity and easy disaster recovery 
• Email and collaboration – teams within workplaces can make use of shared calendars, hold meetings and conferences via cloud-based video calling software, and collaborate on documents in real-time
• Remote working – cloud-based systems offer secure access to systems from any location, making it ideal for companies that have adopted a remote or hybrid working model
• Business applications – this includes cloud-hosted accounting, CRM and ERP platforms
• Cyber security services – often backed by AI, these services offer real-time monitoring, threat detection and enhanced protection.

Why Cloud Services Matter for Businesses

One of the most obvious benefits of cloud services for businesses is the convenience, but this isn’t all. For many companies, adopting cloud-based tools and platforms can be a clever strategic move. 

Here are just a few of the many benefits:

Cost Efficiency

There’s the potential to make significant savings by making the switch to cloud services. One of the main reasons for this is that there’s no need for a large upfront investment in hardware or IT infrastructure. Many ‘…as a service’ tools and platforms run on a subscription, or you only pay for what you use. This offers flexibility, easier budgeting and the option to spread out the costs.

 

Scalability and Flexibility

With cloud services, resources can easily be scaled up or down as the needs of the business change. If your company is growing, the service can grow with you – with minimal disruption. 

 

Improved Security and Reliability

An area where cloud systems really shine is cyber security. They offer enterprise-grade security, including regular automatic security updates, as well as built-in backups to reduce risk and downtime.

 

Better Focus on Core Operations

With cloud services, all of the core IT infrastructure and maintenance are handled by managed IT support specialists. This allows your teams to focus on what they do best.
