Public Cloud: Digital transformation has considerably changed organizations’ routines, demanding the need to adapt to the new times in the IT sector.
For example, those who still need to work with cloud computing are falling behind and being swallowed up by competitors.
Has your company yet to enter this migration process? Understand the public cloud and clear your doubts on the subject.
What Is A Public Cloud?
The public cloud is a model in which it becomes possible to virtualize services and hardware resources, allowing IT collaborators to develop solutions, make them run in these environments, and store data in shared cloud computing locations where several other users share the same resources.
It is important to emphasize that this does not mean that other public cloud users have access to individual databases — inviolability is guaranteed by the service provider company’s information security mechanisms and protocols.
Any entity can become a public cloud provider. But it is essential to rely on companies that offer more reliable and stable services to ensure greater security for data and applications.
Public And Private Clouds
Private and public clouds have the same configuration, using specific technologies to virtualize resources that developers can use in their solutions.
While private clouds are systems dedicated to contracting users, the public cloud is provided, as a shared service, providing resources to multiple users. And we can still include, on this list, the hybrid cloud, which is when two or more cloud environments are combined, which can be public or private.
When we talk about benefits, compared to the private cloud, it tends to be less costly since costs are shared with other public cloud users. In addition, it is a service with simpler management, facilitating the functions of employees responsible for managing cloud applications.
On the other hand, compared to the different models, there is the disadvantage of the security of the information circulating there, especially when we talk about confidential data for organizations. Another complicated point is a longer response time to requests since thousands of other users will request the infrastructure service.
How Is The Current Use Of The Public Cloud?
For some companies that are migrating to the cloud now, the public mode is usually chosen, as it is a good start for good strategies and offers greater data mobility.
With this, less sensitive data that does not require so much secrecy can be viewed and edited through mobile devices, ensuring greater flexibility for the company’s internal functions.
It is also widely used for non-delicate data backups. Therefore, in the event of a system failure, information in the public cloud can be used to ensure the continuity of tasks.
It is frequently used by companies looking for an adaptation period before investing in a private cloud or for SMEs that still need greater budgetary control and cannot count on personal service.
It is important to emphasize that, despite all the support offered by the service provider regarding firmware updates, service availability, and essential information security features, it is the user’s responsibility to apply patches and more complex configurations.
What Solutions Does The Public Cloud Offer?
Some of the services that the cloud offers to its users are:
- IaaS ( Infrastructure as a Service ): the company uses the infrastructure resources available in the cloud;
- PaaS ( Platform as a Service ): is the hosting and implementation service for hardware and software to promote applications in the online environment;
- SaaS ( Software as a Service ): the solution is hosted and runs directly on the cloud computing services.
What Precautions Should Be Taken When Using It?
When a company starts to apply the cloud in its day-to-day life, necessary precautions must be taken to avoid problems that compromise its use over time. See the main ones below.
Look At Your Public Cloud Vendor
One point, for example, is that the service is integrated into your company’s IT infrastructure. Therefore, finding a good service that allows this type of functionality is essential. In addition, it is vital to have a reliable organization with the necessary support in case of unavailability and problems.
Take Care Of Data Security
Another fundamental point is to take care of information security. This is because, although the supplier has its protocols, the shared nature of the cloud is quite delicate for the maintenance of more sensitive data in this environment.
Therefore, the organizations’ IT managers must have their own care measures in this area. Some tips are:
- avoid using an open network to access the public cloud;
- apply your company-specific security protocols;
- train and make the organization’s users aware of essential security measures (such as access passwords);
- implement an access level policy in your company.
Understand How The Payment For The Use Of The Public Cloud Works
A common confusion on the part of those responsible for managing the cloud is to understand that payment for the service is not usually made through a monthly fee. Most suppliers work with the amount on demand.
That is, you will only bear the expenses of what you use. To have greater control over costs, it becomes necessary to know the average resource consumption. With this in hand, it is possible to project, more efficiently, what the average expenses will be.
A cloud calculator is one way to understand better and ensure better cost management. Thus, it will be easier to identify how much your IT can cost in the cloud.
Implementing the public cloud in your business can be an alternative to adapting the company to the new IT times. Therefore, it is essential to have the support of a specialized firm that offers all the necessary support.
