Desenvolvimento de um SaaS multiplataforma utilizando o modelo multi-tenancy no contexto de computação em nuvem

Abstract

With the advancement and growth of the Internet, many companies have reshaped the way their software is delivered by having them purchased, configured and accessed directly over the Internet, reducing application costs for both the customer and the company, as well as facilitating because you will not have to buy servers to run the applications. This delivery model is called Software as a Service (SaaS) and has been constantly growing in recent years. However, in order to further reduce operational costs, many companies choose to use the same database for multiple clients, which may result in data being viewed by users who do not belong to them, a serious error in the security of this data. To circumvent this problem, these companies choose to use the multi-tenancy model, which is responsible for ensuring that the data is only accessed by its owners, even though it is in the same database. Therefore, this work has as main goal the development and implementation of a SaaS for the management of physiotherapeutic clinics. For this, we analyzed the existing technologies in the market for the development of this type of application and how they communicate with each other. After the implementation, a survey was carried out in the companies that used the application, making the hypothesis raised in this study to be proven, being possible to determine that a software as a service using a single database in conjunction with the multi-tenancy model meets the demands of most applications and ensures data security and integrity as well as software with isolated databases for each customer.
