This talk will focus on Walmart’s home-grown open sourced solution for all workflow orchestration needs - "Concord". We will discuss the extremely rewarding continuous deployment journey that we undertook at Walmart that led us down the path of creating Concord. We will dissect some key successful case studies that Concord helped us solve at Walmart scale. In addition, we will talk about the various challenges we faced and continue to face during our journey and how the fast-changing industry landscape (with respect to continuous delivery of software) influences our growth inside Walmart.

You will be able to understand:

• How we deal with challenges at Walmart scale
• Why we chose to open source our solution
• How we enable a complete CD cycle using Concord
• How Concord empowers deployments in a hybrid cloud model

The practice of Chaos Engineering has established the importance of running resiliency experiments in cloud-native application ecosystems. As the field of Chaos/Resilience Engineering has matured and attained widespread adoption, a need has emerged for engineering organizations to quantify the costs of running such a program. Additionally, sustained investment in any long-running program will require metrics (KPIs) to show effectiveness to Executive Leadership.

In this talk, we will discuss the setup, running and maintenance stages of a high performing Chaos/Resilience engineering program irrespective of the size of the organization. We will analyze the key metrics that should be tracked along with the optimum cadence of chaos exercises. Also, with the rapid advancement of CI/CD tools and cloud deployment technologies, we look at enhancing the impact of chaos engineering by deep integration into the continuous deployment pipeline.
