Cloud computing has long been one of the technological solutions companies invest in and trust the most. In fact, according to a survey conducted before the start of the pandemic by O’Reilly Media, 25% of companies had in mind to migrate all their tools to the cloud within a year. A figure that has probably grown with the rise of teleworking.
The cloud brings numerous advantages, such as low cost, greater efficiency and security, or remote access. Despite this, three recurring questions arise in companies that want to implement it: what exactly is the cloud? What types are there? And which one to implement in each case?
Cloud computing is all those programs or services used and is not physically installed on the computer or equipment. There are three types of cloud: public, private, and hybrid.
To better understand the cloud environment, Serban Tech clarifies the differences between the types of cloud and which one to implement in each case:
Public Cloud: People outside the organization manage this type of cloud ecosystem. In other words, the data and information of a specific company are stored on the servers of its cloud services company, which will be in charge of the administration and maintenance of the infrastructure.
It is important to note that other businesses that use the same cloud service will never have access to that information. Likewise, it offers the advantage of payment for use, so that companies with a smaller volume of work can contract this service only when they need it. Therefore, the public cloud is designed for any company, regardless of its size, for all the advantages it offers.
Private cloud: If the company has stringent security regulations due to the type of data it handles or any other issue, it is the best option. This type of cloud is for exclusive use, which means that both the hardware and the software are dedicated to that specific company.
The advantage of this over the public cloud is security since there is greater control of risks and security mechanisms. Can also customize not only that but the environment to suit different business needs. That is why the public cloud is usually the favourite of large companies looking for a security plus. A great example is financial institutions, which deal with sensitive data that requires more delicate treatment.
Hybrid Cloud: This cloud model combines the advantages of the public and private cloud. When the company needs more computing resources, the hybrid cloud allows you to expand your private cloud or on-premises infrastructure in the public cloud to manage your different workflows with total security.
The hybrid cloud thus provides greater flexibility by having private infrastructure and taking advantage of public resources. All this while maintaining the control and security provided by the personal model and the available cost savings with a pay-per-use system.
Therefore, the hybrid cloud enables companies to pay for the resources they use at a given time, for example, due to an occasional workload, avoiding having to acquire more equipment and additional resources.
The advantages of adopting cloud services are many, from cost reduction to security, comfort and speed.
