What is the right balance between moving fast, innovating, experimenting with new technology, and protecting the personal data of our customers and interests of our stakeholders? How can we safely try new ideas in production without risking costly downtime? Does the utopia where developers are free from lock-in and operators enjoy the calm of a steadily running system exist in the real world? Is it possible to have open platforms with better security? At Kroger Digital we are still working through these questions every day but are redesigning our systems with the goals of true operational maturity and security. Discover how we are building capabilities for monitoring, A/B testing, and continuous delivery with Docker Datacenter, plugins, and open source building blocks such as NGiNX, ElasticSearch, and more.
