Microsoft’s Azure is unquestionably one of the best cloud platforms available for businesses who are looking to migrate to the cloud. But it has different execution models to consider based on your business demands. Two of these are Infrastructure as a Service and Platform as a Service, or IaaS and PaaS.
Choosing between Azure IaaS and PaaS all comes down to whether you need a literal server in the cloud (for IaaS), or need a platform to create software over the web (PaaS).
Both solutions have similar and different variables, along with other concerns that you should be aware of from technology limitation to cost associated.
One thing you’ll discover with both is they give you the best of what the cloud can offer for the most essential tools on the go.
Cost Differences Between Iaas and Paas?
The greatest thing about all Azure services is you have no upfront costs, or termination fees. Plus, you only pay what you use, helping you shape your own budget.
Azure makes the above easier through per-minute billing, making this an incredibly affordable way to start using top-tier cloud services.
You can track your usage through their billing portal, though you can decide what price you really want to pay for either IaaS or PaaS. Thanks to Azure’s pricing calculator, you’ll add what you want in the way of services and see what it costs based on region.
How Scalable Are IaaS and PaaS?
Both platforms operate through the cloud, scalability is quite expansive, including scaling to multiple instances without redeploying. With the ability to scale easily in either one, you’ll expand your infrastructure or platform instantly when experiencing business growth virtually overnight.
You can count on both Azure Iaas and PaaS having high availability along with scalability . With high availability in all Azure platforms, you’ll be assured they continue to exhibit all expected functional and non-functional characteristics.
Each module and design have an associated SLA.
Pros and Cons With PaaS
One thing you’ll appreciate is the low total cost of ownership with PaaS thanks to automated server maintenance, no license requirements among others.
PaaS is a little harder to transition to the cloud. Portability issues are also well-known, yet depends on how or where you use it. Which makes it a perfect candidate for newly created applications and databases.
Pros and Cons With IaaS
Unlike PaaS, Azure’s IaaS gives you a quick transition to your cloud service. You even get a more mature ISV ecosystem, and more complete control, especially for disaster recovery.
IaaS is more expensive to operate, so keep this in mind for your budget. In addition, it requires more rigorous server maintenance.
Conclusion from an IT professional point of view
As you can see, not all features in these Azure platforms are alike. Both IaaS and PaaS don’t have fast deployment, though Microsoft’s SaaS application does.
You can run your own machine image in IaaS, yet can’t in PaaS. It’s the same combination for complex installations or software configurations.
