A public cloud is a 3rd-party IT management software program that hosts various on-demand offerings and physical infrastructure through the internet. There are three categories of it –
- SaaS (Software-as-a-service)
- IaaS (Infrastructure-as-a-service)
- PaaS (Platform-as-a-service)
Each of these models work quite differently than one another. However, they can be used by a company in order to access different resources or technologies without hosting them through a corporate-owned data structure.
Note: A public cloud will essentially offer an opportunity to rent equipment, storage, as well as software virtually. Whilst organizations can host private clouds in their own server, almost anyone can purchase these services and share their use securely.
How Does Public Clouds Work?
The way this type of cloud computing works is pretty simple.
For example, if you are looking for some additional storage capacity or resources, it might be best for you to opt for a public cloud. They’ll charge you by time or byte while providing you with their services. This, in turn, can help you save a lot of money, as you are only paying for the service or component you need. The services can be customized as per your requirements.
Essentially, the provider of the public cloud will become the resource manager of their clients. The processing capabilities, infrastructure, applications, and storage – everything will be taken care of by the same person. All of these technologies or resources are generally pulled into an information-accumulation lake, which is managed and maintained by the vendor.
Now, if one of their clientele needs it, the same is transmitted through the internet. And you’re charged by the provider, depending on whatever you are using.
Why Should You Use a Public Cloud?
Cloud adoption has been on the rise since the beginning of the previous decade. According to a report, almost 91% of businesses in the world are currently using at least one public cloud.
The adoption rate is expected to grow even more, considering how quickly and efficiently the web is becoming an integral part of the business. But, why are so many people using it?
Let’s find out more about it.
1: Low Upfront Expenses
Creating a full-fledged IT structure will require a massive investment. And if you are thinking about outsourcing everything, it can be even trickier to cramp everything in your budget.
However as a user of the public cloud, you can easily avoid any kind of outsourceable upfront cost. Plus, you will only be paying for the services you are using on a monthly basis.
In addition, there is no need to pay any additional money on the maintenance, as the vendor of the service will take care of it. So, offering them the monthly commission will be enough.
2: Excellent Accessibility
With cloud services, you can comfortably access your data, software, or usable platform from anywhere you want. So, it will be an excellent choice for someone working remotely.
Besides, in most cases, a public cloud might also be used from a mobile phone, depending on the option you have chosen. So, you can send or receive data and manage it on the go.
As the platform can be accessed from anywhere, you can also collaborate with your team with urgency and without any complacency. And everything will get updated in real time. So, there is no need to worry about losing a certain piece of data or anything as such.
3: Admirable Scalability
Public clouds are highly scalable. They’re flexible and, therefore, can be used in any way you want them to. If needed, various new features and systems can be added there as well.
Comparing that to an IT infrastructure, you will always need to add something whenever you are making an upgrade. This, in turn, will affect your budget and put a halt to your operations.
On the other hand, public clouds can easily keep up with whatever need your business has. In addition, it can also be used if you are thinking about scaling back without spending any cash.
Moreover, with it, you can scale the processing power, networking, and data storage capacity of your systems easily. There’s no need to worry about disruptions at all.
Public clouds are highly reliable, especially when we are comparing it to an in-house structure or an on-premise system. And there are two reasons behind it, including –
- In this case, the provider is going to access and maintain a specific network of servers on their own. So, the risk of total failure tends to be somewhat rare. Even if one server is malfunctioning, you can use another one to pick up the slack instantly.
- Furthermore, a public cloud can back whatever data you have entered or implemented in it. Therefore, even if your business ins undergoing a technological failure, you will not have to deal with any security threat at all. The data can be restored easily too.
Are There Any Risks Associated with It?
No matter how you look at it, public cloud seems to be quite efficient in almost every accord. But, there are still some shortcomings associated with it that might haunt you later on.
Here’s what you need to know about them.
- Unlike a private cloud ecosystem, a public cloud is entirely based on a shared system or environment. So, the risk of a data breach tends to be quite high in this regard. So if you want to take care of this issue internally, investing in workload protection might be beneficial for you and your organization.
- With public clouds the vendor can make any change they want without thinking twice. Hence, you might lose an integral feature in the process, which, in turn, can diminish a functionality and make you less productive. If you want to take care of this situation, it might be better to use a hybrid cloud for your purpose.
The Bottom Line
Like any other cloud computing option, public cloud, too, comes with its own issues. But they are quite manageable on their part. So, make sure to take a few precautions and start using it.
