We discuss elaborate security features in Chapters 6 and 7. • DevOps: DXP methodology also supports and uses various open- source DevOps features such as Agile Delivery (such as Agile Management with Slack or Jira); continuous integration or CI (such as Jenkins); iterative testing; container deployment (Docker or Kubernetes); etc. • Other Services: It can also support third-party integration of open- source features available in the market, such as Rules Engine, Journey Analytics (Google web Analytics, Open Web Analytics, similar web, etc.), Appstore support/integration (Google Playstore/Apple appstore), IoT services (Iotivity), wearable services, and reporting services. Evolution and Drivers for DXP In this section we discuss the various stages of evolution of digital platforms and the key drivers of DXPs. Evolution of Digital Platforms Various stages of evolution of digital platforms are shown in Figure 1-2. 11
