At AWS re:Invent 2021, the emphasis is on the modernization of cloud-native environments, highlighting the intertwined nature of IT modernization and business strategy, especially in the context of COVID-19 recovery plans. The event underscores the rising reliance on cloud computing infrastructure, with a notable increase in public cloud usage by 35% in 2021, as organizations navigate digital transformation journeys. Despite the widespread adoption of multicloud architectures, with over 80% of organizations utilizing them, challenges persist in managing cloud complexity and observability, as highlighted by a survey where 95% of respondents reported visibility issues leading to performance problems. The conference explores AI-driven observability solutions, which aim to alleviate these challenges by enabling automated issue detection and resolution, thereby enhancing application reliability and security. It also highlights the growing adoption of DevSecOps practices, which integrate development, security, and operations teams to ensure the creation of secure, high-quality application code. Dynatrace is featured as a key solution provider, offering automated and intelligent observability tools to support cloud-native environments, and will present sessions on tackling cloud complexity and enhancing software delivery through AWS Lambda and microservices architectures.
