The Future Stack: How Container-as-a-Service Enables Next-Gen PaaS
Platform as a Service (PaaS), either home-grown or cloud hosted, has proven to be an important component in accelerating and normalizing the delivery of a variety of reliable, scalable cloud applications. Traditionally these PaaS products were restrictive in that they generally limited developer choice to a specific programming language and required developers to conform to a specific application lifecycle model. The alternative was to use raw infrastructure as a service (IaaS) which forces tremendous work onto developers in the form of machine and operating system management.
More recently, container orchestration or container-as-a-service (CaaS) is emerging as a sweet spot between virtual machine infrastructure and platform as a service. CaaS provides a more flexible foundation than traditional PaaS while still enabling developers to focus on their application and forget about the machines on which it is running. This means enterprises are able to innovate more quickly, creating a modern platform that supports the delivery of reliable and scalable solutions.
Interestingly, CaaS is becoming the new infrastructure foundation, enabling the rapid development of next-generation PaaS products that build on top of this core container-as-a-service foundation. These new PaaS's enable developers to use the power of PaaS for rapid development, and step down to lower-level abstractions when it is necessary. The combination of CaaS and next-generation PaaS provide developers with the tools need to rapidly and reliably build and deploy all aspects of their application while still focusing on managing the app, rather than machines.
