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 and resolve doubts such as, “What is better Paas vs SaaS?
Cloud computing came less than 5 years ago and yet we feel that we are hearing about Paas vs Saas much longer ago. 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.
The IaaS deployments, PaaS, SaaS, hybrids and multi cloud are becoming very popular, so choosing the technology best suited for migration to the cloud becomes increasingly important.
Paas vs. SaaS: Making Sense of IaaS, PaaS, and SaaS for cloud migration
Before choosing between Paas vs Saas and determining the type of service that will allow the business to optimize business capabilities in the cloud, it is necessary to understand the differences that exist between the main cloud services . Having clear 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. Thus, in broad strokes it could be established that:
- 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 way to start moving to the cloud . The main advantage of this option is the fact that it facilitates the installation of specific applications, aimed at covering the needs related to certain processes and tasks. No need to think about IaaS or PaaS, SaaS drives cost savings across the organization, eliminating complex maintenance tasks that tie IT down, and avoiding having to deploy generic or large-scale products. So, when doubting between PaaS vs Saas, in this case, software as a service would be the best option.
- Platform as a service (PaaS): Sound more complex? It is precisely one of its most outstanding benefits. PaaS enables you to adopt components of cloud computing to gain control over 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 the moment. Taking this into account, between PaaS vs Saas, we would choose the first one. Of course, when considering this business model, you have to choose between implementing PaaS partially with public cloud infrastructure or taking it to the field 100%.
- Infrastructure as a service (IaaS): IaaS, PaaS and SaaS allow you to take advantage of all the advantages of cloud computing, increasing the efficiency of migrations ; But why go for infrastructure instead of platform or software as a service? Unlike SaaS and PaaS, an IaaS migration is equivalent to taking control of data , applications and even cloud operating systems. Scalability is another advantage of this alternative that, in addition, leaves the freedom to use any software or platform that needs to be used in each case.
