Cloud computing has undoubtedly had an impact on the way compute, networks and storage are managed, not to mention the provision of numerous other business services which are now available via the cloud. Although a hugely prominent buzzword in the IT industry, cloud still carries an air of uncertainty for many businesses. In this article, we tackle some of the common private cloud myths and assumptions we have come across:
1. Cloud offers less security than in-house solutions – Myth
On the contrary, cloud service providers have invested heavily in their data centres. And they have far greater security resources at their disposal. Furthermore, private clouds place security directly in the hands of the client. This means you have complete control to implement the same levels as security as are present in the rest of your organisation. Remote access can also be protected through the same mechanisms use in traditional data centres. Of course, there’s never a 100% guarantee. But the point here is that the security offered by your cloud provider is likely to be every bit as good, if not better, than that which you can provision in-house.
2. You have less control in the cloud – Myth
Although public cloud comes with certain limitations, private cloud users have much greater levels of control. Private cloud is still a managed service so users get many of the benefits of cloud including scalability, resilience, flexibility and support. However, because the hardware is used solely by one customer, that customer has much more control over security, operating systems, configurations and applications.
3. All cloud is the same – Myth
One of the great benefits of cloud is the flexibility it offers. Cloud makes it possible to start small and grow as your business demands. Furthermore, hybrid cloud options make it very easy for companies to pick and choose the services and cloud models that will benefit them as a company. And whilst still maintaining other functions in house. In short, cloud should be designed, tailored and built to each company’s needs. So no two cloud solutions are likely to be the same.
4. Our business has no use for cloud – Myth
In reality a large majority of business are already using cloud in some form. Users may be utilising Google drives, Amazon services or other public cloud resources without an IT department even being aware. It may, therefore, not be as big a leap as you might imagine to consider other functions which could usefully be migrated to the cloud. Indeed, by not being open to such considerations, businesses could be foregoing valuable capabilities and efficiencies that would increase their competitive advantage.
5. Cloud is a new phenomenon – Myth
Cloud may be evolving. The way it is implemented and utilised is changing and expanding along with it. But private clouds have been around for many years and used by companies worldwide. In contrast to the passing fad some may consider cloud to be, the technology is actually proven and very well established.
6. Virtualisation is the same as private cloud – Myth
Virtualisation undoubtedly contributes towards enabling cloud but it does not constitute cloud by itself. By consolidating servers and workloads, virtualisation reduces infrastructure costs and increases agility. Bboth of which help to deliver the value we see in cloud and enable the transition to cloud. But, true cloud takes these benefits away from your own data centre and places them in a remote, managed and scalable environment where they are enhanced and delivered as a pay-as-you-go based service.
7. Cloud is always the answer – Myth
Cloud can offer many benefits from speed of provisioning and flexible costs to scalability, simplified management and automation. But the value of these benefits will vary on a case by case basis meaning cloud may not be the best solution in every scenario. What’s more, cloud is a largely umbrella term encompassing many different models so there are multiple options to choose from. In many cases, a combination of cloud models turns out to be the best solution.
The decision-making process should begin with a number of pre-defined objectives. By first identifying the problem to be solved, it becomes possible to hone in on the pros and cons of each cloud model or service to reach the right solution for you.
