 The Synchronizer uses a jitter mechanism to avoid thrashing the NGINX Plus hosts. Each `core.ServerUpdateEvent` instance 
 is added to the "nkl-synchronizer" queue with a random jitter value between 250 and 750 milliseconds.

-- Create a new K8s Controller, that will monitor specified k8s Services, and then send API calls to an external Nginx Plus server to manage Nginx Upstream servers automatically.  
-- This will `synchronize` the K8s Service Endpoint list, with the Nginx LB server's Upstream server list.  
-- The primary use case is for tracking the NodePort IP:Port definitions for the Nginx Ingress Controller's `nginx-ingress Service`.  
-- With the Nginx Plus Server located external to the K8s cluster, this new controller LB function would provide an alternative TCP "Load Balancer Service" for On Premises K8s clusters, which do not have access to a Cloud providers "Service Type LoadBalancer".
-- Make the solution a native Kubernetes Component, running, configured and managed with standard K8s commands.

+# Overview

+- `NKL - Nginx Kubernetes Loadbalancer` is a new K8s Controller from Nginx, that monitors specified K8s Services, and then sends API calls to an external Nginx Plus server to manage Nginx Upstream servers dynamically.  
+- This will `synchronize` the K8s Service Endpoint list, with the Nginx LB Server's upstream list.  
+- The primary use case and Solution provided is for tracking the K8s` NodePort` IP:Port definitions for the Nginx Ingress Controller's `nginx-ingress Service`.  
+- NKL is a native Kubernetes Controller, running, configured and managed with standard K8s commands.
+- NKL paired with the Nginx Plus Server located external to the K8s cluster, this new controller LB function will provide a `TCP Load Balancer Service` for On Premises K8s clusters, which do not have access to a Cloud providers "Service Type LoadBalancer".
+- NKL paired with the Nginx Plus Server located external to the Cluster, using Nginx's advanced HTTP features, provide an `HTTP Load Balancer Service` for Enterprise traffic management solutions, such as:
+  - MultiCluster Active/Active Load Balancing
+  - Horizontal Cluster Scaling
+  - HTTP Split Clients - for A/B, Blue/Green, and Canary test and production traffic steering.  Allows Cluster operations/maintainence like upgrades, patching, expansion and troubleshooting with no downtime or reloads
+  - Advanced TLS Processing - MutualTLS, OCSP, FIPS, dynamic cert loading
+  - Advanced Security features - Oauth, JWT, App Protect WAF Firewall, Rate and Bandwidth limits
+  - Nginx Java Script (NJS) for custom solutions
+  - Nginx Zone Sync of KeyVal data
