These days it seems that IT and security professionals can’t go a day or week without some new “as-a-service” offering. The proliferation of cloud-powered subscription services has empowered providers to deliver products and software with little or no footprint and management overhead. In the past, limited in-house personnel, costly hardware, and cumbersome implementations often dictated the appetite for new products, software, and services. But now that providers have overcome these issues, businesses’ thirst for new services seems almost unquenchable.
Software-as-a-Service (or SaaS), software applications hosted in the cloud, is perhaps the most popular as-a-Service model currently and ranges from enterprise-grade technologies to consumer-grade products like Netflix and Gmail. Many more types of as-a-Service applications exist, including:
- Platform-as-a-Service (PaaS), or development tools and servers for building applications in the cloud
- Infrastructure-as-Service (IaaS) or servers in the cloud
- Function-as-a-Service (FaaS) or serverless computing in the cloud
Identity-as-a-Service, or IDaaS, is a type of SaaS.
