What is Platform-as-a-Service?
If you’re not sure how to define Platform-as-a-Service (PaaS), you’re not alone. But the technology is well worth understanding, because it’s radically changing software development.
Developers have traditionally leveraged on-site infrastructure components (servers, storage, networking) to design and deploy applications. PaaS recreates this infrastructure in the cloud, allowing developers to engineer both simple and highly complex applications on a pay-as-you-go basis. PaaS providers also offer resources like development tools, libraries and database management systems, so developers using PaaS don’t have to worry about infrastructure logistics at all.
To widen the lens a bit, PaaS is one of three pillars of cloud computing services, along with Software-as-a-Service (SaaS) and Infrastructure-as-a-Service (IaaS). After SaaS, PaaS is the most popular cloud computing type. A recent survey of cloud adoption in the healthcare industry found that 83% of IT organizations use cloud services, and while 70% of them use SaaS, a healthy percentage also use PaaS.
