Deploying Kubernetes in Highly Restrictive Environments
It’s possible and here’s what you need to know
Balancing cloud-native with enterprise governance and security requirements Cloud-native technologies are radically changing the IT landscape. Developed for the cloud, cloud-native is certainly not cloud-bound. Increasingly more companies seek to benefit from cloud-like features in… Read more…
Centralizing Container and Kubernetes Management
Modern enterprise requirements for an agile release lifecycle
While Docker and Kubernetes are at the core of today’s app development paradigm shift, running the new stack reliably and securely requires much more – from security and governance to visibility into applications and infrastructure.
Canary Releases on Kubernetes with Spinnaker, Istio, and Prometheus
Native Kubernetes only vs Kubernetes + additional Open Source Technology
Deploying a new feature or application version can be daunting. Even with today’s advanced testing tools, something can still go wrong once deployed in production. Rolling it out to all users is risky and could have serious business implications.
