…is simply a combination of private cloud(s) and public cloud(s). It can be a constructed using one private cloud with several public clouds or one public cloud with several private clouds. It is basically a mix of at least one private cloud with at least one public cloud. Alternatively, it can be said to be a private enforcement of cloud computing services and infrastructure.
Narrowing down, a cloud is simply a virtual location containing computing resources. This may be owned by someone else or some other entity. These resources are available on demand and at a price. A private cloud is basically a marketing term for this kind of computing architecture that provides a hosted service to a limited number of people behind a firewall. It is also sometimes referred to as a corporate or internal cloud. It’s managed by the organisation it serves.
Similarly so, a public cloud refers to the same kind of cloud computing model, only that here, the service provider makes the resources open to the public via the internet, using a pay-per-usage model. The main difference between a public and private cloud is that a public cloud is offered as a service usually over an internet connection while a private cloud is deployed inside a firewall and is managed by the user organisation.
So, how does a Hybrid Cloud work?
Simple. A vendor who has a private cloud may form a partnership with a public cloud provider. Alternatively, a public cloud provider may form a partnership with private cloud vendors. This allows businesses to take advantage of the cost effectiveness and scalability of the public cloud environment while at the same time ensuring the same level of privacy and security. Additionally there are a number of software vendors that provide a management control panel to enable areas such as encryption and role-based management from within the corporate network whilst ‘bursting’ out items such as storage to a public cloud.
By having the combined benefits of both public and private clouds, hybrid clouds are looked at as the best cloud solutions. Some of the benefits include improved security and data privacy, lower implementation costs due to improved economies of scale, fewer wasted resources because users pay for only what they require, as well as proper utilisation with minimum resource overcapacity and lower maintenance costs.
A major advantage of hybrid cloud computing though, is the fact that you still have and that you retain your dedicated server with all its flexibility while at the same time, you have access to hosted services and applications from cloud hosting providers. This gives you the same level of privacy and autonomy while allowing you to expand your web presence. Simply said, it gives you more control.
Having combined benefits of the private and public clouds, a hybrid has no clear cut downside. Since it offers more control, the risks are directly related to how the user is using it. The more carefully it is controlled, the more secure and efficient it becomes.
So, is the hybrid cloud model the best approach for your business? Leveraging the hybrid model accomplishes several goals which include the fact that it provides a clear use case for public cloud computing. It also acknowledges and validates the fact that not all resources can be stored practically or legally in a public cloud and that some may never even need to exist on these public clouds. A hybrid model is a very valuable architectural approach considering you can mix resources between local infrastructures. All you need is to place your resources on the best platforms, then span the processes between them. Above all, it provides a better option to having some computing cycles with data kept local and some processed remotely. This makes them important elements in making cloud computing valuable for enterprises and more accessible. It also means that this architectural model will become more deployed and increasingly important.
Imagine being able to access all your personal data at any given time. Imagine having all your PC and mobile devices being in sync always. How about the ability to share emails, documents, training movies and all this data, in an instant, with co-workers? These are some of the promised outcomes of cloud computing. Do you know that you are already using some of these new developments? Do you use Google docs? This is one good example of a personal cloud. Simply said, cloud computing is a big step towards a future where all things will be at your finger tips, accessible in an instant, with hybrid cloud computing topping the list.
