When you take a look at the different options you have to make a migration to the cloud, you realize that you are being bombarded with all kinds of "as a service" offers. Therefore, it is necessary to know the fundamentals of IaaS, PaaS and SaaS in order to make the best decision.
Cloud computing came less than 10 years ago and yet we have the impression that we have been hearing about IaaS, PaaS and SaaS for a long time. But this is not the case, and it is demonstrated by the fact that there are many companies that are not yet 100% in the cloud.
IaaS, PaaS, SaaS, hybrid and multicloud deployments are becoming very popular, so choosing the most appropriate technology for a migration to the cloud becomes increasingly important.
Before choosing the type of service that will allow the business to optimize the business capabilities in the cloud, it is necessary to understand the differences that exist between the main ones.
Having clear the benefits of each option and what it implies for the organization in the face of implementation, is the way to make the most correct choice. Before deciding what you really need, can help you get better acquainted with these and similar terms.
Software as a service (SaaS)
It was the alternative used by the first wave of migrations to the cloud. In fact, even today, it is the most popular means to start the transfer to the cloud. The main advantage of this option is the fact that it facilitates the installation of specific applications, oriented to cover the needs related to certain processes and tasks.
No need to think about IaaS or PaaS, SaaS promotes cost savings in the organization, eliminating complex maintenance tasks that tied to IT, and avoiding having to implement generic or large-scale products.
Platform as a service (PaaS)
Does it sound more complex? Precisely it is one of its most outstanding benefits. PaaS allows you to adopt components of cloud computing to gain control at the time of development in an environment like this.
High availability or scalability are characteristics of these platforms, which make it possible to customize applications according to the business needs of each moment.
Of course, when considering this model for the business you have to choose between implementing PaaS partially with public cloud infrastructure or take it to the ground 100%.
Infrastructure as a service (IaaS)
IaaS, PaaS and SaaS allow us to take advantage of all the advantages of cloud computing, increasing efficiency in migrations. But why choose the infrastructure instead of the platform or the software as a service?
Unlike SaaS and PaaS, an IaaS migration is equivalent to taking control of data, applications and even operating systems in the cloud. Scalability is another advantage of this alternative, which also leaves the freedom to use any software or platform that needs to be used in each case.
