Many people talk about cloud as if there is only one variation, when in fact it can be broken up in to multiple disciplines. You will hear a variety of different analogies depending who you talk to about the purpose of each, but ultimately the decision to choose on or the other depends upon what you plan to use your cloud for.
Private cloud is the model that has evolved in most organisations; most have built their own infrastructure and automation for that, using new and efficient methods to facilitate it. However when compared to public cloud they don’t necessarily provide the same amount of flexibility and agility; something which can be restrictive for businesses.
The public cloud in comparison has always been available as a service that can be consumed by all, it appeals and is used by the mass market. Surprisingly, despite the advocating of a private solution, a lot of global organisations adopt public cloud in one manner or another. This solution may be suitable for some of their IT estate, but is certainly not secure enough to provide storage for their most important data and documents.
Considering that both private and public cloud have their own restrictions, often the best way to make the move in to cloud is to combine the two. This is done by opting for a hybrid solution. A hybrid solution can allow you the flexibility and agility of a public cloud, whilst still providing the security a business needs and would receive with a private cloud.
Unsurprisingly, most businesses choose to use a hybrid of public and private cloud.
I have been in the cloud market for many years now, in fact since around 2008 when cloud wasn’t a word that was used commonly at all. But even then we were still looking at advancing these technologies and driving them forward best as we could. Now look how it has grown!
Back then, the words mostly associated with cloud were also our core constraints: flexibility, agility and security. These have been addressed between public, private and hybrid cloud making the things that businesses want and need most available to them.
Cloud has become mainstream and IaaS is a globally adopted technology. Many businesses are looking to move in to cloud but will face the topic being articulated in a variety of manners. They key thing I tend to ask businesses is; how do you plan to consume and use cloud? Simply moving stuff from one place to another may get you some efficiencies but a better placed plan will further increase efficiency, agility and flexibility too.
