Get to Know the Docker Datacenter Networking Updates

The latest release of Docker Datacenter (DDC) on Docker Engine 1.12 brings many new networking features that were designed with service discovery and high availability in mind. As organizations continue their journey towards modernizing legacy apps and microservices architectures, these new features were created to address modern day infrastructure demands. DDC builds on and extends the built-in orchestration capabilities including declarative services, scheduling, networking and security features of Engine 1.12. In addition to these new features, we published a new Reference Architecture to help guide you in designing and implementing this for your unique application requirements.

• DNS for service discovery
• Automatic internal service load balancing
• Cluster-wide transport-layer (L4) load balancing
• Cluster-wide application-layer (L7) load balancing using the new HTTP Routing Mesh (HRM) experimental feature

If a new service is created, how will it know where to find the other services it needs to communicate with? As a service needs to be scaled, what mechanism can be used for Continue reading
