IaaS vs PaaS vs SaaS Model for Cloud Migration: Which is Best?
Enterprises often find themselves stuck in choosing the right type of model when planning a cloud migration; the most popular model options being IaaS (Infrastructure as a Service). PaaS (Platform as a Service), and SaaS (Software as a Service).
In this guide, we have explained the differences between IaaS, PaaS, and SaaS models for cloud migration to help you make informed decisions.
Key Takeaways:
What Are IaaS, PaaS, and SaaS Models in Cloud Migration?
Learn about the three types of cloud migration models below:
1. IaaS (Infrastructure as a Service) cloud migration model
The IaaS (Infrastructure as a Service) model in the context of cloud migration is about opting for cloud infrastructure, such as servers, storage, and networks where a cloud migration tool can be deployed.
For example, a company opts for a cloud infrastructure service, such as AWS EC2, Microsoft Azure Virtual Machines, etc., and deploys an already-available migration tool to move their workloads. This approach falls under the IaaS migration category.
2. PaaS (Platform as a Service) cloud migration model
With the PaaS (Platform as a Service) cloud migration model, companies choose to use PaaS platforms like Google App Engine, Microsoft Azure App Service, etc., to either build their own migration tool to match with their highly specific use case or, in rare cases, heavily modify existing tools.
The PaaS platforms provide tool development capabilities which businesses leverage to build migration tools as per their preferences.
3. SaaS (Software as a Service) cloud migration model
A SaaS (Software as a Service) cloud migration model is designed to provide end-to-end solutions to businesses looking to migrate their users and data from one cloud to another. The migration service provider offers both the migration tool and migration infrastructure to enable seamless migrations.
With CloudFuze’s SaaS cloud migration model, businesses also benefit from a fully managed migration service. Through the managed migration service, businesses get complete handholding from dedicated migration managers and teams.
IaaS vs PaaS vs SaaS Cloud Migration
Here’s a brief comparison that provides a snapshot of the core differences between IaaS, PaaS, and SaaS cloud migration models.
| Aspects | IaaS Cloud Migration | PaaS Cloud Migration | SaaS Cloud Migration |
|---|---|---|---|
| Solution type | Raw infrastructure | Tool development platform | Ready to use tool |
| Service type | Customer manages infrastructure and deploys tools | Customer builds the tool using the software development platform | Customer gets a fully managed tool ready to be used |
| Control level | Customer gets total control | Customer gets medium control | Customer gets granular control |
| Customization | High | Moderate | Depends on the scope |
| Learning curve and time to deployment | High | High | Low |
How to Determine Whether to Use IaaS, PaaS, or SaaS for Cloud Migration?
In order to determine which cloud migration model is right for your company, it is important to understand the migration use case.
If you want full control over the migration infrastructure to be able to configure it in your unique ways, you may consider the IaaS migration model. If you want to build your own migration solution using available software development cloud platforms, then you may consider the PaaS migration model.
However, if you want a ready-to-use cloud migration tool with advanced migration functionalities and readily configured infrastructure in place, then the SaaS cloud migration model will be the right choice.
FACT: Most large enterprises and SMBs (small and medium businesses) choose the SaaS cloud migration model to avoid investing time and resources in configuration migration infrastructure and building their own migration solution.
