Cloud Computing

Cloud computing allows users to access secure and scalable networks of data centers and enables availability of virtually housed data, cloud-native and enterprise applications. Databases and applications are accessed instantly over the Internet rather than through onsite servers or computer memory. Cloud services are typically paid monthly at a cost associated only with what is used and vary in scope from personal to enterprise.

In the most basic sense, “using the cloud” is the act of storing and using information via the Web rather than the memory of servers or personal computers. In this way, more data can be stored, but cloud offers more than just extra space. It’s difficult to imagine how much physical space a global corporation might need to house all its databases, applications and inventory. Cloud-based networks of data centers virtually store all this and more in a fraction of the physical space by using all-flash arrays. Networks of data centers are housed off-site where they take up literally zilch internal office space for enterprise users.

What are the advantages?

Cloud computing allows end-users to increase output thanks to the rapid speed at which applications and information are brought to screens. The agility of public cloud allows worldwide use of internally created applications and enterprise applications too. Use only as much space as you need without the burden of paying for too much space or the worry that you won’t have enough. All of this increases speed, lowers overhead and allows for growth from sole proprietorship to worldwide venture. Housing data on a virtual, private network that expands with your company means you’ll always have access to programs, applications and files you need to keep flying.

What’s the difference between cloud for consumers and enterprise cloud?

Cloud for consumers is almost always an open cloud system that is offered as a place to store items like images or documents. These small silos offer the advantage of housing information outside personal computers but lack efficiency offered by enterprise cloud, which is tooled with expansive speed and memory not found on personal desktops. An enterprise cloud is scaled to suit the needs of everything from small to behemoth-sized corporate structures and can handle juggernaut workloads day in and day out. Virtually no number of operations will slow down true enterprise cloud, which stays afloat with far less fuss than in-house servers and certainly less than server farms, which require entire armies of IT wizards. Cloud for corporate structures is private and can be slow when purveyors don’t utilize enterprise cloud to deliver public cloud-like service, which does the heavy lifting with lightning speed. The winning idea is to have private cloud with public cloud agility and speed. 

Does cloud computing work on hybrid clouds?

Well, not exactly. The phrase “hybrid cloud” actually refers to a type of computing environment, which utilizes a mixed bag of public and private cloud with a virtual bridge connecting them. This system can work well for entities that have large stores of private data but that also work in teams on public cloud services such as Microsoft Azure. A hybrid cloud environment can be particularly valuable to ventures that have a lot of ups and downs as opposed to a relatively steady sales stream without peaks and valleys. If your company has a big season around the holidays and lags around summer, hybrid cloud could be for you. With a hybrid cloud the right automation and orchestration are essential for keeping the public and private clouds accessible, safe against hacks and running like a top.

Is there more than one kind of cloud computing?

Cloud computing can be broken down into three major categories: software as a service (SaaS), infrastructure as a service (IaaS) and platform as a service (PaaS).


Smart time and project management are the name of the game with SaaS, which lets you manage everything from your operating system to your network and data you house in cloud. SaaS uses the power of the Web to bring users the third-party applications they need to run their businesses. SaaS delivers software-like applications without a need to purchase physical software or download anything new. Because you can work within a SaaS right from almost any Web browser, there's no need to run additional programs in the background. 


You might benefit from IaaS if you’re already well-versed in operating a specific application but need assistance from a third-party that owns the large-scale hardware. IaaS offers third-party management of this hardware and allows you to scale up and tear down quickly. IaaS allows you to pay for what you need and nothing more, but if you end up needing more later you can provision for it in a snap.


With PaaS, you get the scaffolding you need to hang applications. Create, grow or deepen the capabilities of an application that SaaS and IaaS just don't offer. PaaS is really only for the skilled developer and offers ways to test new applications once they've been built. This "virtualization" means developers can keep working on apps until they’ve made every tweak their hearts desire.
