Cloud computing has taken over the world by storm the past few years. It has created such a buzz that even the most common layman would have heard it at least a couple of times in his life.
This concept, though has come to be spoken about widely only in the past few years, it has been in use for at least a decade now. Some very common examples of cloud solutions are Gmail, Facebook, Dropbox, Skype and PayPal.
So what exactly is cloud computing ?
Cloud Computing is Internet-based computing, whereby shared resources, software and information are provided to computers and other devices on-demand, like the electricity grid. So as learnxpress puts it, “Cloud computing is a culmination of numerous attempts at large scale computing with seamless access to virtually limitless resources.”
The main idea behind the cloud is for you to be able to access all your information over the internet without having to know the details of the infrastructure used to enable it. It works similar to the concept of call routing in cell phone companies.
It was forecasted last year that the global cloud services market would be worth a whopping $180 billion for 2015 with 50 million physical servers in the world. This goes on to show the growing significance of cloud computing in today’s world.
Why cloud computing?
Many companies are using cloud computing today either directly or indirectly because of its various advantages:
Flexibile: One of the biggest benefits of cloud computing is its flexibility. It can be used by people located at different geographies to access applications and also work through the internet. So, if your business have fluctuating bandwidth and expanding demands, shifting base to cloud should be your ideal solution. If in the future, your needs heighten/decline, it’s convenient to scale up your cloud capacity or cutting it short drawing on the service’s remote servers without having to let the entire network go down. And the opposite too works as easily. The agility that cloud offers can help you stay one step ahead of your competition at all times.
Security: In the virtual world, security of data is one of the biggest concerns that plague companies and individuals. If you lose your computer, you are at the risk of losing pretty much everything. More than the equipment itself, you need a way to save the data that is used by you on a regular basis. This is when Cloud Computing comes in handy as it gives you greater security. Since all the data you have is stored in a cloud, you can access it from wherever regardless of the machine that you’re using. Not only that, what is more interesting is the fact that you can wipe off all the data from the lost laptop even when you don’t have it with you to avoid data getting wrong hands.
Automatic software update: There are updates having in softwares on a regular basis and if you are on a cloud network, then you’re one of the few lucky ones that will experience that update taking places regularly without any interruption. Suppliers roll out updates regular that take care of themselves and help you save time on maintaining things by yourself. In the process, you are free to concentrate on the bigger picture and make your business grow.
Increased team collaboration: When there are different people located in different places yet working on the same project, collaboration becomes a challenge, not with Cloud Computing though. In fact, it contributes towards an increased team collaboration across geographies as your team can access, edit and share documents from anywhere at any time. This helps people to work together in perfect co-ordination with each other. The cloud computing file sharing apps and work-flow helps your team make updates in real time.
Work from anywhere: Cloud computing enables people to work from anywhere as long as they have a working internet connecting. Also, you can use any device that you have as most of cloud services provide apps compatible on different devices. This can help you facilitate a work-life balance for your employees so that they can adapt a model that works best for them without productivity having to suffer.
Environment friendly: Using cloud computing it not only good for your business but for the environment too. How so? Well, by using cloud services, you’re also reducing your carbon footprints. When your cloud needs fluctuate, your server capacity scales up and down to fit helping you use only that much energy that you actually require. And, in today’s world with so much global warming taking place, we need to contribute to the environment the best way we can.
Cost effective: Opting for cloud services, you’ll also contribute towards maximizing the budget of your firm. It reduces your maintenance fee as there are no more servers, software and update fee required any more. There are many hidden costs like software implementation, customization, hardware, maintenance, and training that are all rolled into one subscription fee.
Key concepts that govern cloud computing
There are certain key concepts associated with basics of cloud computing that govern this service. It helps to know a little about them. Read on to know more:
Platform (PaaS): It is a model to run applications without having the hassle to maintain the hardware and software infrastructure at your company. Organizations regardless of their sizes have adopted the PaaS solutions for the simplicity, scalability, and reliability that it offers. PaaS applications don't need constant upgrade.
Software (SaaS): According to novaitsolutions.in, in this software distribution model, applications are hosted by a vendor or service provider and made available to customers over a network, typically the Internet. SaaS is "becoming an increasingly prevalent delivery model as underlying technologies that support Web services and service-oriented architecture. (Rouse, 2010, para 2).
Infrastructure (IaaS): This form of cloud computing provides virtualized computing resources over the Internet. IaaS is one of three main categories of cloud computing services, along with the above mentioned two. In this model, a third-party provider hosts hardware, software, servers, storage and other infrastructure components on behalf of its users.
Services-based application programming interface (API): An abbreviation of application program interface is a set of routines, protocols, and tools for building software applications. The API specifies how software components should interact and APIs are used when programming graphical user interface (GUI) components. A good API makes it easier to develop a program by providing all the building blocks. A programmer then puts the blocks together.
If you haven’t moved to cloud yet, then the above mentioned benefits should be enough for you to make a decision. Just make sure that you know the key concepts well enough to understand which of the models to opt for.
