Cloud computing: What is it? All the Information You Need

Cloud computing is the provision of technological services such as servers, comprehensive analysis, network administration, databases, information storage, and software through systems on the Internet. Cloud providers charge according to the business’s nature and the package’s particularity. 

Imagine a company where all its workers can work with the same program in different places without needing to install the software on their PCs. This can be done thanks to cloud computing. They can even access it from their mobile phone.

Be careful; right now, you are using a cloud service viewing this page in your browser since this page is stored on a web server on the Internet, that is, in the Cloud.

You have accessed this page through “the cloud” or through “the cloud.”

Another example would be the photos you store on Google or Instagram or the Gmail mail service (your emails are in the Cloud, not on your computer).

There are cloud services that we already use regularly, such as those seen above. Still, the aim of cloud services in the future, some of which are already present, is that computers do not need a hard drive since all the information and programs will be in the Cloud, that is, on the Internet, and you can access them from your computer

 

Among the main functionalities of cloud computing are:

  • Application development and other services.
  • Data analysis and create models or patterns of predictions in business.
  • Software development and administration.
  • Data storage, backup, and recovery.
  • Sharing of videos, photos, and audio.
  • Website hosting services.

Advantages of cloud computing

 

1. Support and trust

Cloud computing allows backup of stored data and disaster recovery while the objectives of organizations and businesses continue to be executed. One of the main functions is to house the information in the correct places to avoid redundancy of information or the use of unnecessary spaces.

2. Low cost in the acquisition of applications and optimization of resources.

3. Performance

The largest and most far-reaching cloud computing services run in global networks of secure data centers constantly updated with fast, efficient hardware. This is an important guarantee for the IT administration of companies and institutions.

4. Productivity

Cloud computing is a very important support for the IT department to direct it to tasks of greater relevance and performance. The maintenance resources of a local data center (hardware configuration, security patches, among other tasks) are drastically reduced through cloud computing technology.

5. Speed

Most cloud computing providers are built on self-service features to allocate various computing resources, allowing companies flexibility and reducing technology planning.

Other important advantages of the Cloud are that: 

  • You do not require a specific computer; you can access it from any computer.
  • All the software (programs) will be in the Cloud; hence the stress of installing company software on your PC will be eliminated. 
  • The Cloud provider will undertake updating of all software on the PC. 
  • Your provider is in charge of managing the software.
  • You can share information globally.
  • Obtain resources easily and cheaply.
  • Thousands or millions of people use the same program in the Cloud without the need to buy one each. This makes the costs cheaper.
  • The payment to be paid by the client varies depending on the use made of the contracted cloud computing service.
  • The computers will not have to be very powerful since the programs run in the Cloud. Yes, now it will depend on your internet connection.
  • You contract the basics and just what you need, but you can automatically expand what you have contracted by telling your cloud provider. Of course, you will surely have to pay more, but it is an advantage that you can do it almost instantly. This is known as Scalability
  • If your computer crashes, nothing happens; everything is in the Cloud.
  • Ability to isolate the IT resources contracted to the cloud service provider from the client’s IT equipment. 
  • Regarding security, cloud providers should have great security measures, but sometimes this is not the case.
  • Avoid capital expenditures on hardware, software, IT support, and information security by outsourcing infrastructure/platforms/services.

Disadvantages of Cloud computing

  • The information no longer belongs to you because it is stored on external servers. You can’t be sure who accesses that information.
  • Hackers can target the information you store.
  • A hacker is more likely to try to access the Cloud than a private PC.
  • What is obtained by the hacker is much higher.
  • If internet access fails, the Cloud is over.
  • You won’t be able to do practically anything.
  • The access speed will depend on your bandwidth. However, it will always be less than the speed you already have on your hard drive.
  • Cloud servers can be physically anywhere in the world.
  • If there is a problem, what law or laws should apply? This can be a problem for some companies.
  • Ownership problems may arise since if your information is no longer on your computer, who does it belong to? 
  • Legal problems could arise. 

Types of cloud deployment 

Public Cloud

The public Cloud is created, executed, and operated by direct providers of this service, and these deliver computing resources of servers and storage on the Internet. The public Cloud fully supplies the supporting hardware, software, and infrastructure; the provider usually gives you an account through a web browser.

 

Private Cloud

Private cloud services and their computing resources are for the exclusive use of a single company or organization. This may be physically located in the company’s data center or a product provider’s data center. Specifically, the private Cloud is one in which the services and infrastructure are maintained in a private network.

Hybrid Cloud

Hybrid Cloud emanates from the collaboration of public and private Cloud. 

This system is united by a technology that allows data and applications to be shared with each other. A flow of data and information through the private and public Cloud is an opportunity to improve the way the company or organization implements.

What are the 3 types of cloud computing services?

Before selecting a type of cloud service, it is necessary to know what the following 3 classifications consist of:

1. Infrastructure as a Service (IaaS):

It is an infrastructure of instantaneous computing and is managed through the Internet. One of its main features is to avoid additional costs and the complexity of managing servers or data centers. You only need to purchase the features that you only need to use. The service provider manages the infrastructure while the company installs, configures, and manages its own software, operating system, and applications.

Advantages of IaaS:

Business continuity and disaster recovery enhancements: IaaS provides high availability, continuity, and disaster recovery at no additional cost while you can access your data.

Stability and reliability: with IaaS, there is no need to maintain, update software or hardware, or solve problems within the team since the service provider is in charge of the infrastructure.

Adaptation to business conditions: Agile and rapid availability of resources to adapt to increases in application demand. Once the situation returns to normal, resources are reduced so as not to invest additional resources.

  

2. Platform as a Service (PaaS)

It is a cloud development environment, from simple cloud-based applications to complex cloud-enabled business applications. A provider of this service provides you with the resources through secure access through English. The Platform as a Service is the indicated solution to guarantee the life cycle of web applications: design, tests, implementation, administration, and updating. PaaS includes development tools, database management, business intelligence services, and analytics.

Advantages of PaaS:

Reduced coding time – PaaS development tools reduce the time spent coding new apps with pre-coded app components.

Modern technological tools: the PaaS model allows organizations and companies to access analytical and business intelligence tools.

Cross-Platform Development: Opportunities to develop on various platforms such as desktop, mobile, and browsers that allow faster and easier creation of applications.

3. Software as a Service (SaaS):

Software as a service allows the connection and use of cloud-based applications through the Internet. Common situations are email services and collaboration tools such as Microsoft Office 365. SaaS offers the use of an application to users to connect to them through the Internet; All the software infrastructure and the stored data are located in the data center of the supplier company, which is in charge of managing the maintenance of the software and hardware.

 

Advantages of SaaS:

Premium access to applications: SaaS provides users with highly relevant applications and systems for the competitiveness of their data, resources, or strategies, such as ERP, and The investment is very accessible.

Free access to cloud solutions: You can run most SaaS applications from the web without special or additional download or installation.

Access to data from anywhere: with information stored in the Cloud, users can access it from any device, be it mobile or desktop. 

 

Wrapping up: 

The rising need for data storage by many companies and its outsourcing is responsible for the great advance and evolution of cloud computing. With cloud solutions, the need for large investments and fixed costs are eliminated, transforming providers into service companies that offer computing capacity on-demand flexibly and instantaneously, just as the appearance of the Internet generated a revolution in business and economic models during the last three decades and was an engine of development for all countries.

Cloud computing is a new breaking point for the world economy in general and the technology and professional services sector in particular. Although defining a scenario in the Cloud is a task that requires the full participation of the IT and administrative team, it is important to analyze the amount of internal information, and the applied uses, before identifying opportunities for improvement.
