Confused by the jargon around cloud computing? We agree. Choosing the right cloud service is crucial. But can seem highly overwhelming.
The wrong choice can lead to spiralling costs, security vulnerabilities, or even non-compliance with data regulations.
One misstep, and you’re looking at setbacks that can take years to rectify.
Read on to get a nuanced understanding of the cloud landscape and learn how to make the best choices for your business.
Types of Clouds: One Size Does Not Fit All
In a comprehensive article by RedHat, cloud computing can be categorised into four main types:
- Private Clouds
- Public Clouds
- Multi-Clouds
- Hybrid Clouds
And within each of these are services often referred to as IaaS, PaaS, and SaaS.
A bit jargon heavy? Worry not. These services signify their operational scope: Infrastructure, Platform, or Software.
Public Clouds: Flexibility at a Price
Public clouds like AWS and Google Cloud are open for business to anyone and can run off-premises or even in your own data centre.
While they offer immense flexibility, the shared nature of there is argument that these clouds might expose you to various security risks.
Private Clouds: Your Own Fortress
Private clouds are, by default, dedicated to one user or a group.
They can now be set up off-premises and managed by third-party vendors, offering different subtypes like Managed and Dedicated clouds. Private clouds provide enhanced security, but this comes at the cost of scalability and investment in hardware.
The Hybrids and Multi-clouds: Best of Both Worlds
Hybrid clouds are a mix of public and private clouds, allowing workloads to move freely between environments.
Multi-clouds, on the other hand, are a strategy involving multiple cloud services from different vendors. Both offer a balanced approach but require complex management and orchestration platforms.
Cloud Services Unpacked: IaaS, PaaS, and SaaS
IaaS involves renting the infrastructure, while PaaS provides a platform for application development, and SaaS delivers a ready-to-use application over the internet.
Each has its own set of advantages and challenges.
IaaS: You manage the OS and applications, but the service provider takes care of the hardware.
PaaS: Ideal for developers; you focus on the app, and the service provider takes care of the rest.
SaaS: Think Google Docs or Microsoft 365; it’s all managed for you, accessible via a browser.
The Final Question: What Suits You Best?
Deciding between cloud services depends on various factors like cost, security, and resources.
Public clouds usually entail operational expenses, while private clouds demand capital investment. Hybrids offer a pretty flexible middle ground.

Choosing between on-premises, public cloud, or hybrid cloud is an important decision to consider – especially surrounding the specific needs and security requirements of your business.
Each option has its advantages and disadvantages in terms of security, scalability, cost, and control.
On-Premises
On-premises infrastructure provides your business with a high level of control and security as the data is stored within your own premises.
Which can be beneficial if you absolutely need strong control over your IT workloads and underlying infrastructure. Often the case with large enterprises or those with stringent regulatory requirements. But, on-premises infrastructure often requires significant upfront investment in hardware and a host of ongoing maintenance costs.
Public Cloud
Public cloud services, as mentioned earlier, offer scalability and flexibility to meet unpredictable workload demands.
Plus, they also provide cost-effective solutions as they operate on a pay-as-you-use model, reducing the need for upfront investment in hardware. Security in the public cloud depends on the provider’s security protocols and practices. According to a global survey, AWS is the most trusted public cloud provider for data and application security.
Hybrid Cloud
Best of both worlds, hybrid cloud solutions combine the benefits of both public and private clouds.
They provide flexibility and scalability from the public cloud while maintaining control and security for sensitive data in the private cloud. But, managing a hybrid cloud environment can be highly complex and may require additional investment in integration and management tools.
In terms of security, it’s important to note that no option is inherently more secure than the others.
The security of your data and applications depends on how well the security controls are implemented and managed. According to a survey, 52% of businesses prefer cloud solutions that have their own native security tools. And what are the most important features to look for in a cloud provider? Tom’s Guide suggests strong encryption protocols, two-factor authentication (2FA), and minimum password standards.
The choice between on-premises, public cloud, and hybrid cloud should be based on the specific needs, resources, and risk tolerance of your business. It’s essential to thoroughly evaluate the advantages and disadvantages of each option, considering factors like cost, control, scalability, and most importantly, security.
