A Beginner’s Guide to Cloud Computing
Cloud computing can be defined as a process in which you deliver hosting services via the internet. Depending on the usage, cloud services can be private or public. For example, a public cloud tends to ‘sell’ services to someone on the internet. Whereas the private cloud is kind of a proprietary data or network center that provides hosted services to specific people, with particular permissions and access settings.
Whether it’s private computing or public, the ultimate goal is always to allow feasible, measurable access to IT networks and computing sources. Cloud computing services are divided into 3 major categories: platform as a service (PaaS), infrastructure as a service (IaaS), and software as a service (SaaS).
Cloud infrastructure consists of the software and hardware components that are needed for the proper execution of a cloud computing model. Moreover, cloud computing can also be referred to as on-demand or utility computing.
Interestingly, the term cloud computing has been originated from the cloud symbol that’s we often use to portray internet usage in various diagrams and flowcharts.
How Does It Work?
Cloud computing functions by permitting user devices to access data through the internet, from various computers, databases, and servers, etc.
An internet connection tends to link the front end (including the user device, network, browser, and cloud software applications) with the back end, which contains computers, databases, and servers. The back end works by storing the information that’s being accessed by the front end.
All the communication between the back and front ends is controlled by a central server. This server relies on specific controls to promote the data exchange. It requires both middleware and software to facilitate connectivity between various user devices and cloud servers. Generally, there is always a dedicated server for each of these individual applications.
However, cloud computing functions majorly depend on internet signals. Therefore, you need to make sure that you have a stable and high-coverage internet connection like CenturyLink internet so that your computing process does not get interrupted in between. CenturyLink Internet is extremely affordable for all types of users; their packages are starting from $50 per month only. How cool is that?
Also, they provide you with instant connectivity! For more information, simply dial 1-855-349-9310 now and send your queries to their customer services helpline.
Examples of Cloud Computing
Google Docs and Microsoft Office 365: Clients can easily access Microsoft Office 365 and Google Docs via the internet from absolutely anywhere in the world. Therefore, their computing experience tends to become more effective if they get an opportunity to access work spreadsheets or presentations saved in the cloud at their feasible time.
Email, Skype, Calendar, and WhatsApp: All these apps/software take benefit of the cloud’s capability to facilitate access to stored information remotely so they can get their hands on professional/personal data on any device, whenever they want.
Zoom: Zoom is also a cloud-based platform used for audio or video conferencing that keeps a track of all meetings and stores them in the cloud, which enables the users to view them from anywhere at any time of the day.
Cloud Computing Advantages
Cloud computing offers a variety of advantages to different businesses and personal-use devices. We are mentioning the top ones below!
Cost Saving: Cloud computing infrastructure and its efficient usage can drastically reduce costs, as businesses don’t need to spend a massive amount of money to buy and maintain various equipment. This also lowers down their overall company expenditure costs because they no longer need to invest in utilities, hardware, software, or even in building huge data centers to facilitate their growing business revenue.
Cloud computing is also beneficial in cutting down costs related to downtime. As downtime happens once in a blue moon only, businesses don’t need to invest their time, effort, and money to sort out any issues that might be related to downtime.
Mobility: Storing data in the cloud indicates that clients can access it from any place of the world, with any device via a stable internet connection. That certainly means clients do not have to carry their data on USB drives, a hard drive, or even a bundle of CDs to use their data. Instead, they can simply access it through their cellphones, laptops, tablets, or other devices.
This is one of the most powerful and reliable ways for remote employees as well to remain connected with all information and customer profiles. Cloud users can easily store, retrieve, process and recover large resources in the cloud.
Disaster Recovery: Who doesn’t worry about unpredictable data loss? I am sure we all do. Cloud computing is the most amazing way to store your data and take its regular backup so that you never lose it. Even in case of emergencies or power outages, you can always recover your data from cloud-based services via multiple devices like computers, cellphone, laptops, and tablets, etc.
Cloud Computing Vendors
The cloud service industry certainly has an abundance of providers. The top three largest cloud service providers who are ruling over the market are:
- Amazon Web Services (AWS)
- Microsoft Azure
- Google Cloud Platform
The list is pretty long; some other ones include:
- Oracle Cloud
There are specific considerations that should always be taken before you invest in a good-quality cloud computing system. Although most of the cloud services are based on a pay-per-use model, still, several providers provide variations in their prices. Moreover, if the cloud service provider is also going to store ‘sensitive data’, then the physical location of its servers also needs to be considered and taken care of.
Finally, do not forget to ensure having stable internet connectivity at your home/workplace before you invest in a cloud computing service. After all, the cloud servers depend on internet signals to store and retrieve your information from remote locations. For your ease, you can always choose high-speed, reliable, and secure internet connections like Spectrum which provides you with instant connectivity.
