At the same time, however, if you really want to understand how to make the most of cloud IT services, it can help a lot to grasp at least the basics of what the term cloud IT services actually means both in theory and in practice. With that in mind, here is a quick guide to what you really need to know about cloud IT services.
Cloud IT services are basically virtualized pooled resources
The basic idea behind the cloud is that a group of clients has access to a shared pool of resources, which are delivered on-demand through a network. Although the most visible implementation of this is probably the public cloud services which are delivered over the internet, it is also entirely possible to implement clouds privately, in fact there can be very good reasons for doing so.
The basics of private cloud IT services
Since we’ve said that clouds are virtualized pooled resources, we can use a swimming pool as an analogy. A private cloud can be compared to a private swimming pool. It’s basically the same as a public swimming pool, except it’s for the sole use of a single group of people. The owner of the pool can do whatever they want with it. They have complete control not just over how it looks and what equipment it contains, but also who gets access to it where and when (and how).
Unlike public clouds, which are always deployed on the premises of the cloud vendor, private clouds can be deployed either at a company’s business premises or at a site which is owned by a third party, usually a cloud IT services provider, but managed on behalf of a sole client, known as a tenant.
Private clouds are generally preferred when companies want the benefits of cloud technology, but still need to maintain the very highest standards of data security, at least for some of their data. It is increasingly common for companies to use both private and public clouds (to create what is known as a hybrid cloud), thus getting the best of both worlds.
With control, however, comes responsibility, in other words, if you have a private cloud, it’s your job to manage it. Managing a private cloud does not, however, mean that you have to do everything yourself. You can, for example, get a cloud IT services provider to manage your private cloud for you. If you’re going down this route then you may want to give strong preference to local cloud IT service providers. For example, if you’re in Sacramento, CA then look for a company which provides cloud IT services in Sacramento, CA.
This may seem counterintuitive, but the reality is that keeping everything local can go a long way to making life simpler for everyone. Your data will be held under your local laws and any disputes between you and your cloud IT service provider will be resolved both under those same laws and by local courts. On a more pleasant note, it can also make for a much more convenient working relationship for both you and your partner and hence help them to deliver better service for you.
Public clouds are somewhat like public swimming pools, they are owned and run by third parties and third parties buy access to them. It’s entirely down to the public cloud vendor to decide who does and does not get access to their cloud IT services platform and under what conditions. Just like in real life, tenants do not get any direct say in who their neighbors are, although they do get to choose the cloud vendors with whom they do business and it’s wise to stick with reputable ones.
Where the swimming pool analogy does fall down is that in a public cloud all tenants should be effectively invisible to each other. In other words, a public cloud should look and feel exactly like a private cloud with the exception that everything is managed for you. On the one hand, this means that customers effectively lose the right to set their own terms for everything and have to work within the framework of the cloud IT service. On the other hand this approach can save time and hassle as well as money, plus increase flexibility and scalability.
