Legacy software vendors that traditionally provide on-premise solutions still face a couple of architectural challenges. Those allow them to provide cloud-native applications as well as a solid foundation for offering a natural bedrock on which to construct bots, ultimately allowing them to offer a conversational user experience.
Cloud Architecture
Many vendors of legacy software struggle to accomplish a smooth transition from a monolithic architecture to a cloud-enabled service oriented architecture, as such a transition involves rewriting, which comes at a significant price. However, the previous economic benefit of re-architecting to ensure a more efficient use of compute and storage resources is gone due to increasingly cheaper IaaS and PaaS services.
