Cloud computing has the potential to transform your business IT. Discover the difference between private cloud and public cloud computing models and learn how to choose the cloud computing model that best fits your business needs.
There are three options to consider:Each comes with significant business benefits. But which option is best for your organisation varies greatly depending on your computing support and security requirements.
In this guide we'll delve into the contrasts between private cloud vs public cloud, and explore the pros and cons of the hybrid cloud computing model. We'll provide valuable insights, that will empower you to choose the ideal cloud computing solution for your business.
The shift to cloud computing has been rising for over a decade. However, with the increase in remote and hybrid working, the move has accelerated as businesses of all sizes look to stay competitive, resilient and innovative.
One of the most significant advantages of cloud computing is its accessibility, allowing your teams to work anytime, anywhere. This efficiency and the need to streamline business processes mean cloud technologies are more popular than ever.
But what is cloud computing, and how does it work?
Cloud computing is a service that allows users to access applications, data, servers and more via the internet. The term is based on the idea of a cloud being a central location where you can store data or run applications.
Led by a Managed Services Provider (MSP) like M247, cloud computing offers an alternative to installing and maintaining on-premise software, such as in-house servers or data centres. Not only does it offer a more secure solution, it also takes away the associated capital expenses (CapEx) of owning your own infrastructure.
The MSP will make cloud services available, and businesses typically only pay for what they use, according to their requirements. This pay-as-you-go model can greatly benefit businesses in managing and predicting their IT budgets.
Along with cost savings, there are many advantages of moving to cloud computing, including enhanced security, scalability, and flexibility.
Cloud computing services can be organised into four broad categories:

Advantages
Lower costs with a subscription-based pricing tier and no CapEx
Easy to deploy as the cloud provider owns the infrastructure
High flexibility and scalability to meet workload and user demands
Save time and money as the cloud provider manages it
Downsides
Less technical control since your IT infrastructure is in the hands of the provider
Security vulnerabilities as the risk of a breach can be greater in a shared environment
Limited customisation with a one-size-fits-all approach for all shared users
Lack of visibility means you can end up paying more than you expect
How much does it cost?
Typically, public clouds are sold according to subscription-based or pay-per-usage pricing models. There’s also no CapEx with cloud computing, making it an attractive choice for organisations that don’t have the investment to deploy and maintain the IT infrastructure.
Usage patterns determine the cost of the public cloud. However, this isn’t always easy to predict. So, if you get it wrong, the costs could spike, and you might not find out until it’s too late.
When to use the public cloud
A public cloud provides an affordable and flexible option, ideal for smaller or growing businesses. But this option offers the least visibility and control into the infrastructure, which might not be the best choice for organisations with regulatory compliance obligations.
While multiple businesses share a public cloud, a private cloud is dedicated solely to a single organisation, and the cloud computing resources are delivered through a secure private network, making this one of the key differences between a private cloud vs public cloud.
How does it work?
With a private cloud, you can either host data on-premise or off-site by a third-party service provider.
As the services and infrastructure aren’t shared with any other organisation, a private cloud offers a more secure setting. However, this puts the responsibility of security wholly on a business, so it’s important to consider whether you have the technical expertise to work with a private cloud alone. If not, there is the option to work with a MSP. This highlights a crucial differentiation between public cloud and private cloud.
Some of the big private cloud computing companies include:

Advantages
Customisable to meet the unique needs of your business
Predictable server usage, so it can be easier to forecast and manage costs
More control over your data and infrastructure
Meet compliance with greater control over your data
Downsides
Higher costs to set up, maintain and staff the infrastructure
Slower to deploy, with technical expertise required
Limited scalability, often requiring more time and resources to adjust
The decision of selecting your cloud computing model is not just between the private cloud vs public cloud. There is also a third option available - the hybrid cloud. A hybrid cloud combines a private and public cloud into a single, flexible infrastructure to run workloads. By connecting private cloud services and public clouds, organisations have the flexibility to choose the best cloud for each application.
How does it work?
You can use public clouds for high-volume work with lower security requirements, such as emails, while the private cloud is in place for more sensitive operations requiring a higher level of security.
Protecting systems and data across multiple cloud environments can be more complicated, so it’s important to keep in mind that investing in your cybersecurity is essential when considering a hybrid cloud service.
Some big public hybrid cloud computing companies include:
Advantages
Flexibility to transfer resources from an on-site private cloud to a public cloud and vice versa
Improved security by keeping sensitive data on a dedicated infrastructure you have more control over
Use existing resources and infrastructure to lower costs and achieve a good ROI
Customise the private end of your hybrid cloud model to meet your specific needs
Downsides
More complex to implement and manage
Limited visibility of your cloud environment
Network bottlenecks can occur when transferring data between private and public clouds
Security challenges when mixing the infrastructure of both private and public clouds
How much does it cost?
There are too many metrics to answer that high level. However, with the cost of the software needed to build and manage your cloud, server costs and interconnection costs, a hybrid cloud can potentially have a high total cost of ownership.
Furthermore, switching between private cloud vs public cloud can be hard to track, which can cause wasteful spending.
When to use a hybrid cloud
A hybrid cloud can come at a higher cost. Still, its improved flexibility and security make it the perfect choice for businesses that already have the systems and resources in place to move between different operations according to their needs.
A hybrid approach will be necessary for organisations with legacy applications in the backend that are vital to their operations. Similarly, an organisation might keep its sensitive data on a private cloud but have specific systems they’re comfortable hosting on a public tab. If you're unsure how to settle the Private Cloud vs Public Cloud debate, then Hybrid Cloud may be the solution for you.
As cyber attacks continue to grow in sophistication, cloud security remains a primary concern for businesses considering making the move.
With various- plans in place and centralised security, cloud providers offer a secure data backup and storage solution, with the cloud steadily surpassing on-premise security solutions. However, like its legacy IT environment counterparts, cloud security should be a top priority for any organisation.
What is cloud security?
Cloud security refers to the tools, procedures and best practices used to protect cloud environments and your critical data.
In a nutshell, cloud security comprises:
Who is responsible for cloud security?
It is important to remember that most cloud solutions, including AWS and Microsoft Azure, run on a shared responsibility model.
This means an organisation’s MSP is not solely responsible for security. Instead, the MSP is responsible for ensuring the infrastructure is secure, such as the physical protection of its servers. The cloud customer is then responsible for what they can control, such as user accountability.
How do I keep my data secure on the cloud?
While the cloud provides a highly secure data backup and storage, taking your own steps to safeguard your data is critical. Adhering to standard cybersecurity practices is essential to protecting your data in the cloud.
Here are four ways you can increase cloud security:
Most importantly, things can go wrong. Whether intentional or accidental, data loss can have detrimental effects on a business. Be sure to have robust backup and disaster recovery protocols to protect your reputation, minimise downtime and reduce the risk of complete data loss if the worst happens.
Cloud migration is moving your workloads, such as data and applications, to the cloud – and it’s an integral part of any organisation’s cloud adoption. However, knowing how to make the shift and where to start can be a daunting prospect.
That’s why having a robust plan in place is critical.
Our 30-minute Digital Transformation – ‘How the Cloud Can Help’ webinar reveals more about understanding your cloud journey and how to plan your cloud migration.

2. Credentials
Whether the MSP has recognised certifications is a good indicator of its expertise. Check for certifications like ISO 27001 and Cyber Essentials, which show a MSP has the security controls to protect confidential data effectively. Credentials such as these demonstrate that the MSP thoroughly understands compliance and regulatory standards.
Reputation is equally essential.
Ask for anonymous testimonials or case studies as evidence of customer success. By asking about their work and how they implement their services, you will be able to determine the right MSP with a successful track record.
3. Capabilities
Do the provider’s expertise and product offerings align with your organisation’s objectives? Are they set up to support a business of your size?
It’s vital to ensure the MSP’s technologies and services meet your needs and that you get the right level of support, not just when you’re getting started but in the long term.
Many providers employ general support staff. It’s important to look for a team of specialists who have an in-depth understanding of cloud technologies and the cyber threat landscape for a more thorough service.
4. Support
Assess each cloud provider’s customer support services to find the right level for your organisation. You want to work with a reliable MSP, so checking its performance in the way of SLAs is a good place to start.
