Cloud computing, or just “Cloud” for simpli­city, can be trou­blesome for some people, while others consider it to be the future of the infor­ma­tion tech­no­logy (IT) enter­prise infra­struc­ture.

Many people still have similar questions to the ones I had a long time ago: “What is cloud, and what can I do with it?”

No, I’m not talking about the white, fluffy-looking things in the sky. However, a Cloud in the tech­no­logy world can be similar (that’s why they named it Cloud!)

These days, if you type the word “cloud” into a search engine, the most common results will probably be cloud computing, cloud provider and cloud solution. According to Wikipedia, cloud is “a group of computing resources in which large groups of remote servers are networked to allow centra­lized data storage, and online access to computer services or resources.”

Got it? No? No problem! Read on for another expla­na­tion.

There was an era where the Internet started to penetrate all conti­nents, and people began to commu­ni­cate with others all over the world. Remember the first time you used a web-based email service like Gmail? There was a folder for your Inbox, and your email data was stored there. It was located somewhere on the Internet, but you didn’t actually know where (the physical location of it). This is a simple example of what I’m talking about: even though the cloud is there, you can’t see or feel it.

The basis of cloud is making use of the Internet and combining it with a shared or private infra­struc­ture that can be accessed using an Internet connec­tion at anytime, anywhere, with suffi­cient bandwidth capacity.

Now that you have a basic under­stan­ding of what cloud is, the questions that needs to be answered is, “So what?”

If you work in IT, you may have already heard this word many times. You may be wondering what you can do with cloud tech­no­logy, how you can utilize it and how you can integrate it with the IT needs of your company.

There are many good cloud providers out there, but which one you end up with depends on your IT needs. I won’t be able to explain all the pros and cons here, but I will try to summarize what cloud computing can do and how it can be used in your company by explai­ning the features that a cloud usually has.

Make your own pizza

Cloud computing is like pizza Private cloud, public cloud, hybrid cloud, you name it. There’s plenty of choice involved in how you want to build your cloud — just like when you make or order a pizza.

Pizza as a Service

Private cloud offers you tons of custo­mi­za­tion; just look at all the private cloud services that are available today.

Public cloud is consi­dered to be quick and simple; with a public cloud, creating your cloud infra­struc­ture is only a couple of clicks away.

Hybrid cloud offers you a combi­na­tion of both, when you need to have certain parts custo­mized, but still want the simpli­city of provi­si­o­ning.

Pay for what you use

The title says it all. Depending on the needs of your IT, you can transfer all your capital expense and invest­ment into an opera­ti­onal or subscrip­tion model. With an operating expense (OPEX) model, there is no initial invest­ment, and you pay what you subscribe or use.

Rather than buying such a big box (including server, storage and network devices) that you may not need at the end of the day, you can choose a different, more gradual and modular route. As your business grows, your capacity grows, and you can provision more capacity by using cloud. You need a devel­op­ment server for testing and quality assurance for three months? Cloud can do it!

However, your cost savings depend on what you’re doing. At some point, cloud subscrip­tions can end up costing more than buying a box would have.

Hybrid-cloud

One question that I usually ask my clients is, “How are you managing your envi­ron­ment today?”

With cloud, the auto­ma­tion, provi­si­o­ning and moni­to­ring all depends on the cloud provider. The stream­lined and simpli­fied process for having and accessing these features is just getting better and better. Every cloud provider has its own way of providing cloud as a service, either as an infra­struc­ture (IaaS), platform (PaaS) or software (SaaS).

Getting rid of all your servers, storage and network may not be the best solution (you still need some), but the idea is to have one single portal to manage it all.

So there you have it: the basic capa­bi­li­ties of many cloud providers out there. As you can see, they offer plenty of benefits. Now that you under­stand the basics, you can compare different offering and solutions, to find the one that best suits your IT needs.

What do you think is best for your orga­ni­za­tion?
