What is Cloud Computing?
Cloud computing is a technology that lets remote admission, from anywhere in the world and at any time, to software, file storage and data processing over the Internet, without the need for connecting to a personal computer or local attendant.
In other words, cloud computing usages the connectivity and large scale of the Internet to crowd the most diverse resources, programs and information. It allows the user to access them through any computer, tablet or cell phone.
If it still wasn’t clear, let me exemplify it: if you’ve ever edited a document in Google Docs, attended to music on Spotify, or watched a movie on Netflix, you had direct interaction with cloud computing.
All of them are online facilities that do not require downloading, installing, or accessing any software or folder on your computer. You only need a browser and a decent internet connection to use them.
What are the Uses of Cloud Computing?
Let’s analyze the traditional computing model, in which users and companies need to invest in downloads, hardware, operating systems and software to run some application. It is easy to comprehend why cloud computing has become so popular.
The cloud emerged to democratize information and improve the experience of those who depend on technological resources on a personal or professional level.
Cloud computing brought with it countless benefits. Opting for a cloud service allows:
1. The Reduction of Costs with Infrastructure
It eliminates capital spending with purchases of hardware and software, installation and maintenance.
2. The Economy of Space
The resources remain stored online.
3. The Centralization of Information
It prevents all data from being kept in different programs, with varying types of authentication and forms of access.
4. Increase or Decrease
Thanks to the elasticity power that provides the ideal amount of resources, storage and processing.
5. Remote Work
Company officials can access all data through any computer, notebook, tablet or smartphone, as long as they connect to the Internet.
Besides, we can mention the security, the automatic updating of the server, the platforms’ usability, the technical assistance services and backups.
Amid so many benefits, cloud computing has become the favourite option for many companies and users in general. Not surprisingly, practically everything we currently consume on the Internet – social networks, file storage, video streaming and music – comes from requests and services hosted in the cloud.
How does Cloud Computing Work?
Cloud computing uses a remote waiter to connect user devices to centralized resources.
A small server stores all the data and programs you need, and it can be in your own country or on the other side of the ecosphere, for example, in Japan.
The fact is that you can admission them online, from anywhere, even if they are stored miles away.
What are the Types of Cloud Computing?
There are three types of cloud computing as public, private, and hybrid. If you have a business and you plan to use a cloud service, keep in mind that the choice will depend on factors connected to cost, availability, performance and expectations. Next, you will see how each cloud works:
1. Public Cloud
They are computational capitals, such as servers and storage, provided by a third party and obtainable to any person or company that needs to hire them.
In this classical, the customer is responsible for what will send to the cloud, be it a backup, an application or some records.
In contrast, the cloud breadwinner takes care of the maintenance, security and management of all capitals.
And also, in the public cloud, everything is obtainable on the web and is shared among multiple users using it simultaneously (but separately), keeping resources standardized.
By offering unified solutions, this model ends up being inexpensive. Therefore, the public cloud indicates for businesses that want to save on investment.
2. Private Cloud
In this model, the company upholds the cloud infrastructure in its internal domain and offers restricted access to designated users, such as officers and partners.
The private cloud offers the company the ability to customize the functions and support to their needs.
The cloud is designed exclusively for it; all processes directly to the business’s reality.
In general, organizations must follow certain specific regulations and standards on data and information security and privacy. It is the case of some financial and government institutions, use private cloud use.
3. Hybrid Cloud
Finally, when we converse about the hybrid cloud, we mention the union of the preceding two: the mixture that allows data and applications to share between them.
According to the need and business strategy, resources use privately, others use publicly or link through technologies.
What Services does Cloud Computing have?
Today, cloud computing offers a wide variety of services, tools, and functionalities to meet companies’ needs. Among the leading offers, three models stand out:
1. SaaS (Software as a Service)
The SaaS allows access to software without purchasing its license, using it for free from the cloud, often with insufficient resources.
However, there are also some plans in which a fixed rate charge varies according to use without cost.
The resource offers advertisements or other form of monetization.
In this arrangement, the company accesses the software over the Internet without worrying about installation, configuration and investment in certificates.
Many CRMs and CRM for real estate ERPs work finished SaaS. Email services and other public requests, such as Skype, WhatsApp, LinkedIn and Facebook, also make efforts with this. Therefore, it is the most general mechanism.
2. PaaS (Platform as a Service)
In this cloud perfect, a complete on-demand development environment contract allows it to create, modify, and optimize software and applications.
The PaaS model’s advantage is operating systems, development tools, database management systems, and Business Intelligence services. And many other resources, as well as all the necessary infrastructure to run or improve web or mobile applications.
The development side only has to worry about the application’s programming, since the administration, maintenance and updating of the infrastructure are in charge of the provider.
In the IaaS model, infrastructure resources are borrowed, such as servers, routers, racks, data centres, hardware, and other tools that allow data transmission and storage.
Depending on the provider and the chosen model, the company may be charged, for example, the number of servers used and the quantity of data stored or trafficked.
In the IaaS model, you use what is necessary according to its demand and only pay for what you use.
The great advantage of this perfect is its scalability. After all, in a month, you can require some virtual waiters to store little data and have little traffic. While, the following month, you can ask for double the resources.
Thus, the mechanism works like contracting a cable TV service. It is possible to cancel, increase or decrease it at any time.
Now that you are clear about the concept of cloud computing, I recommend that you reflect on your business’s needs and priorities before thinking about the best model for your company.
It is based on them that you will decide which services are fundamental and need this type of investment.
Defining your available budget will also help you choose the best implementation system: SaaS, PaaS, or IaaS. Analyze the resources and functionalities you need and look for the providers that offer it, for example, cryptography. And other security methodologies, efficient backup services, 24-hour technical assistance, etc.
However, it is always good to approach the cloud, in the beginning, as an environment for experimentation and testing.
