Recently, "architecture subversion, standard guidance and continuous delivery" - China Cloud Science's winter conference was held online. In order to comply with the trend of digital transformation and achieve the breakthrough of ICT IT infrastructure, help customers better cope with the high requirements for application delivery and network security in the digital economy era, and meet customers' application sustainability based on dual activity or multi cloud and multi activity in a dual track (ICT not ICT) environment, Shenzhou Cloud Science, standing at the strategic height of application sustainability, proposed the strategic idea of "1521", It is hoped that through a dual track maximum availability architecture (DTMAA for short), five engines, two series of products of Yunke Rongyi+Yunke Tongming Lake, and a set of Guidelines for Testing the Sustainability of Financial Information Innovation Applications, enterprises can speed up the digital process.? The White Paper on Application Sustainability Architecture and Verification in the Digital Age was released. iResearch, together with Shenzhou Yunke, Tongming Lake Yunhe Information Innovation Research Institute and Tongming Zhiyun, will release the White Paper on Application Sustainability Architecture and Verification in the Digital Age in the industry today. The white paper pointed out that the application sustainability architecture should start from the architecture itself: only when the overall architecture and key nodes are stable, can the modules be assembled flexibly. However, only when the modules are agile, the dual activation and disaster recovery between different data centers, the connection and migration between traditional architecture and cloud native architecture, and the connection and migration between non information innovation devices and information innovation devices can be easily completed without the awareness of the business side. The specific features of the application sustainable architecture include: double live and double track, multi protocol docking, seamless docking with modern technology stack, observable throughout the life cycle, dynamically scalable load, active resilience, multiple modes of docking and integration, etc. The architecture subversion and dual track ultra-high availability architecture are the acceleration of independent innovation of key technologies in the digital era, bringing great sustainability challenges to the customer's application localization process. Application sustainability is a key technology in the digital era. For enterprises, business sustainability is largely related to application sustainability. Especially in extreme cases, customers' applications need to maintain continuous service, including sudden pressure, security risks, iterative processes, disasters and other situations, to continue to provide high-quality services. According to the survey, when 52% of Chinese customers choose sustainability first, it will be the best sustainable service to unify the traditional architecture and cloud native architecture and achieve compatibility and collaboration. Wu Jingtao, Vice President of Shenzhou Yunke and Vice President of Tongming Lake Yunhe Xinchuang Research Institute, said that, "On the one hand, how to ensure the stability of information innovation products and bridge the gap between performance and enterprise application requirements; on the other hand, in the face of the challenges of compliance, risk and innovation, how does Cloud Yuansheng achieve trusted open source and cross domain collaboration. The dual track ultra high availability architecture (DTMAA) came into being under such a background." Through the innovation of the architecture, China Cloud Science has proposed a dual track ultra-high availability architecture (DTMAA) in the industry. So called DTM
