Single instance
App is Reactive
Deals with sockets
Limited resources
Culture / DevOps / Cloud Maturity
Support containers and VMs
Propagation of huge data sets
@lcalcote
The Challenge
On-the-fly intelligent rendering
Distribution of content
Extremely low latency for Reactive services
Blocking vs non-blocking
On-premises telemetry collection and
analytics
Shaping Up
Characteristics ofMicroservices
small, autonomous services that work together.
how small is small?
independent, autonomous service
self-contained functional unit
@lcalcote
Who has a system that istoo big and that you’d
like to break down?Can a small team manage it?
More moving partsincreases complexity.
Can you make a change to aservice and deploy it by itself
without changing anything else?
Faster delivery, rolling updatesHorizontal scale out on-demand;
on an individual service basis
Modular architectureEasy integration and deploymentsService isolation, resilience and fail-safe recovery

Benefits of Microservices- a quick review
Democratization of language and technology choice

Why Nginx
Hybrid needs
On-premises and Google Cloud Platform
Consistent administration and capabilities
central load balancing and proxy platform
Support for VM and container-based technologies withminimal configuration change Deeper feature set available as services/team matures
use as an Application Delivery Controller
@lcalcote
Platform independence
Microbloat v2Going deeper with Nginx & Kubernetes
Service Discovery with Nginx PlusNeed for locating service instances instantly without reconfiguring
On-the-fly Reconfiguration API
Work with etcd
As an ingress controller in Kubernetes SSL termination
Path-based rules
Multiple host names
