The market is entering a new chapter in cloud and digital Customer Expectations Continue to Rise The empowered customer is increasingly savvy and expects a highly personalized experience, one that is consistent across channels. The cause of this rising expectations is fairly clear and Uber, Amazon, Airbnb, Netflix are the disruptors of their industries. “Each time a consumer is exposed to an improved digital experience, their expectations are immediately reset to a new higher level.”  SPEED is More Important than Ever "It's no longer the big beating the small, but the fast beating the slow." Indeed the challenge for many legacy brands is that they struggle to move as rapidly towards the future that digital disruptors have already staked out. Digital Transformation means Business Transformation Enterprises need to recognize that evolving to a true digital value proposition isn't just about digital, but requires in many cases a re- invention of major portions of the business including core technology systems, operating processes and business models "Digital transformation is a fundamental shift in how a firm delivers value and drives revenue." What problems are customers trying to solve? IBM Think 2020 / May 5-6 2020 / © 2020 IBM Corporation
Infrastructure Efficiency Containers significantly reduce the overhead on compute resources — particularly memory. This enables far more workloads per physical server since each share a single host OS, meaning only one copy of the kernel and system libraries is running per system. Greater Scalability Greater scalability is garnered through the use of container orchestration systems like Kubernetes that can automatically place workloads on the least-used node in a container cluster and dynamically scale the number of container instances up and down in response to changing application usage Greater Agility in Application Delivery This increase is a result of the low resource overhead of containers that allows new instances to be deployed in seconds. DevOps Organizations Creation Containers facilitate the integration of developers and IT operations into DevOps organizations that can accelerate application testing and delivery. New Application Creation Containers combine deployment agility, process automation, and application scalability, allowing developers to rapidly explore and prototype new ideas while encouraging them to design differently. A different approach helps developers take advantage of distributed container systems, along with their dynamic scalability and frictionless startup and shutdown processes. How containers can help ?
