What is Cloud Computing?

What is Cloud Computing? Before I write about What is a private cloud computing, I will start writing about Cloud Computing. Before writing more in the Private Cloud, there may be from readers who still do not understand what it's about Cloud Computing. For it in this blog, we will discuss in advance what the heck is Cloud Computing?

Cloud Computing? certainly many of those readers who have often heard the word.

Cloud Computing is a computing model, where resources such as processors, storage, network, and software to be abstract and provided as a service on the network using remote access patterns. Model billing of these services are generally similar to the modern public service. Availability of on-demand according to the needs, easy to control, dynamic and almost without limit scalability are some important attributes of cloud computing.

Possible for common people, when reading the explanation remains unclear. For that, I will try to explain it in language that is easier with the following analogy.

Of course we are all users of electricity in everyday life. To be able to have the electricity, we do not need to set up its own power generation infrastructure is not it? we need to do is sign up, and we just pay the cost of electricity based on the amount we use per month.

When we need additional resources for a specific purpose (for example we have the wedding), we just said to add power, and one day when you want to power down again, we just say to the electric service provider. You could say the addition of electric power is the nature of his ELASTIC and (should it) be done immediately.

When using an electric service, we need not bother to think about how the service provider to meet our electricity needs, how when they have damage to the equipment, how the treatment process such tools, etc.

Its core we just know that we can enjoy the power and obligation to pay the fee every month, while the electric company is obligated to meet our needs based on their service level.

Well, the analogy above, it is a little picture of Cloud Computing, Cloud Computing which is tasked to provide services and we are a user / users of the service. We do not need to bother thinking about how they (layananan Cloud Computing providers) to provide such services. The important thing is they can provide services in accordance with the standards of what we need.

We stayed for the service fee paid based on usage, although there is also a provider of exempt layananan his service. When we need additional services, we can ask for immediate addition of the service, and also contrary (ELASTIC).

Based on the type of service it, Cloud Computing is divided into the following:

Software as a Service (SaaS)
Platform as a Service (PaaS)
Infrastructure as a Service (IaaS)

Well, for a description of each of the above services, we discussed again in the next article
