Cloud computing is one of those finds of tech world that has revolutionized the way industry works and expands today. Cloud computing services have been in effect since more than a decade now. However the seed of the idea was in existence much before that. So, the question arises what exactly is Cloud computing?
Cloud Computing Definition & Concept
Institutions define cloud computing for dummies in several ways. One of the most legible one is this:
Cloud computing is a method of delivering information technology (IT) services in which resources are retrieved from the Internet through web-based tools and applications, as opposed to a direct connection to a server.
In other words cloud computing technology is a way for organizations to outsource their need for IT infrastructure & services. Also they don’t have to maintain their on premise storage device or servers. Moreover, cloud computing services give more scalability scope to smaller businesses. Recently, Oracle Cloud has become a popular choice for businesses worldwide.
Types Of Cloud Computing
Various kinds of cloud computing has evolved over the decade. This technology is deployed in many ways today depending on the requirements of the client.
- Public cloud
- Private cloud
- Hybrid cloud
When all the computing resources including servers and storage space is owned and provided by a third-party then it’s called a public cloud. The clients access these services over the internet through a web browser or an app. Microsoft Azure is an example of a third-party cloud service provider.
When a business or organization uses the computing infrastructure and services exclusively for itself then it’s called a private cloud. Private cloud could be either in the form of on-site data center. Also it could be hosted by third-party cloud computing companies. In any case the data is maintained on a private network.
A hybrid cloud, as the name suggests, is a mix of public and private cloud. It gives more flexibility to the client in the form of more deployment options. The seamless sharing of data and other options makes it easier to optimize.
Various Kinds Of Cloud Computing Services
Before you get all excited about this most trending technology on the block and start planning for cloud computing certification, first learn all its aspects. There are three ways in which organizations can avail cloud computing services. These are:
- Platform as a service (PaaS)
- Software as a service (SaaS)
- Infrastructure as a service (IaaS)
Platform As A Service
The cloud computing service provider gives the clients the environment needed to create new software applications. Furthermore the client also gets on-demand platform for testing and managing the product. A Forrester report indicates that by 2020 PaaS business solution has the capability to generate $44 million in revenues.
Software As A Service
In this form of cloud computing service, the client gets to enjoy software applications online via a web browser on their PC, mobile or tablet. The cloud service provider, in turn, takes care of all the hosting, maintaining and upgrading requirements. Usually, this kind of service is available on a pay-as-you-go basis.
Oracle recently predicted “80% of all enterprise (and mission-critical) workloads will move to the cloud by 2025.”
Infrastructure As A Service
When the organization purchases the whole IT infrastructure solution from the cloud service provider, then it falls under this category. The deal could include physical servers, networks, and storage that could be accessed through an IP based connection. Moreover, it may also include operating systems, software applications or virtual machines etc. This kind of cloud service ensures that even small businesses could afford scalability through a pay-as-you-go business model.
Cloud Computing Technology: A Dominating Trend
Recently there has been a tremendous rise in cloud computing companies. The immense scope that it provides to small and medium enterprises makes it hot in demand. Moreover, even bigger businesses could make immense cost cuts in terms of IT infrastructure with this technology. However, cloud computing security is still a bone of contention among tech gurus.
CareerWise Scope Of Cloud Computing
Nevertheless, there has been an increasing demand for experts for cloud computing jobs. This has led to an increasing interest in cloud computing certification. Whatever might be the case, cloud computing still is one of the most rapidly growing technological fields in the industry.
