Enterprises that rely on private cloud-based platform-as-a-service (PaaS) frameworks could be storing up trouble for themselves in years to come, Gartner warned.
The analyst house predicts 80% of organisations that deploy or assemble a self-managed PaaS framework to create applications will end up disappointed with the results.
“In the next three years, many self-managed private PaaS initiatives will fail to meet the IT organisation leadership’s expectations of cloud characteristics,” Gartner said.
“The tension between the forces in favour of private PaaS and those demanding the full public cloud experience will intensify as self-managed private cloud disappoints.”
The company claims enterprises are likely to realise that pursuing a cloud application strategy based on the use of managed private or public PaaS frameworks will be the right way to go.
Gartner further predicts that 70% of private PaaS users will deploy a container service, rather than rely on framework software, to create their apps for ease of use and cost-cutting reasons.
“For advanced technical teams, a container service may be better than a PaaS framework for the desired balance between developer productivity, breadth of viable application architectures, IT operations control and the complexity of the implementation,” said Lydia Leong, vice-president and distinguished analyst at Gartner.
“A container service is also a relatively inexpensive acquisition alternative to PaaS frameworks.”

IoT draws attention to PaaS
PaaS use is often reported to lag behind other types of cloud services, including infrastructure as a service (IaaS) and software as a service (SaaS).
But the trend is expected to change as enterprises look to re-engineer more of their legacy, on-premise applications and move them to the cloud over time.
However, according to Gartner, the rise of the internet of things (IoT) is driving interest in the concept, with the organisation predicting PaaS will become the source of more than 50% of all new IoT applications by 2020.
"IoT adoption will drive additional use of PaaS to implement IoT-centric business applications built around event-driven architecture and IoT data, instead of business applications built around traditional master data," explained Gartner research vice-president Benoit Lheureux.
"IoT-centric business applications will drive a transformation in application design practices that focus on real-time, contextually rich decisions, event-analysis, lightweight workflow and broad access to web-scale data."
