The analyst firm predicts that, by 2020, more than 50% of all new applications developed on PaaS will be IoT-centric, disrupting conventional architecture practices.
"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," said Benoit Lheureux, research VP at Gartner. "New 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."
Most new IoT-centric solutions will be implemented on IoT platforms, a form of multifunctional comprehensive PaaS that is a hybrid, architecturally coherent integration of application platform as a service (aPaaS), integration platform as a service (iPaaS), IoT device management, orchestration and business process management services as a platform (bpmPaaS), database PaaS (dbPaaS), and analytics services.
Gartner also predicts that, through 2018, more than 70% of IT organisations planning a private PaaS will deploy a container service (rather than PaaS framework software).
Instead of constructing a private PaaS using a PaaS framework, many organisations adopt a container service. An advanced container service provides subscribers with self-service access to container-based infrastructure.
It hosts, orchestrates, schedules, scales and ensures the reliability of containers, and it may also provide other capabilities such as monitoring, load balancing and securing container communications.
“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 implementation," said Lydia Leong, VP and distinguished analyst at Gartner. "A container service is also a relatively inexpensive acquisition alternative to PaaS frameworks."
Another Gartner prediction involves 80% of organisations that deploy or assemble self-managed PaaS frameworks not achieving the expected cloud PaaS experience through 2018.
By investing in cloud platforms, enterprise IT leaders are seeking some or all of the key benefits of cloud for their new IT initiatives. However, in the next three years, many self-managed private PaaS initiatives will fail to meet the IT organisation leadership's expectations of cloud characteristics.
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. Managed private (or public) PaaS will emerge as best practices.
"Success with a private cloud (including PaaS) requires a recognition of the essential cultural and organisational changes to IT organisations, as well as technology changes,” said Yefim V. Natis, VP and Gartner Fellow. “Lacking this understanding leads many organisations to stop their PaaS investment at the point of technology deployment – leading to disappointing results down the road.”

By 2019, a mandatory capability for the top five aPaaS providers will be the delivery of both high-productivity and high-control PaaS options, Gartner said.
Large organisations facing a variety of requirements in the bimodal world will prefer aPaaS suites that can provide integrated high-control and high-productivity capabilities and, as such, these service providers will receive preferential treatment in the market. Combined capabilities will become a requirement for a PaaS market leadership.
