Infrastructure

CU Libraries infrastructure is leveraging AWS Cloud Services.

Default Infrasturcture

Kubernetes

Production products are deployed in containers(micro-service) within a kubernetes cluster. Rancher is used for cluster management and deployments.

  1. Highly available
  2. Horizontal Scalable: Products have the ability to scale up or down based on demand.

AWS EKS

The production clusters are using AWS EKS infrastructure with compute nodes using AWS EC2 instances.

AWS EKS runs the Kubernetes control plane across multiple Availability Zones, automatically detects and replaces unhealthy control plane nodes, and provides on-demand, zero downtime upgrades and patching. EKS offers a 99.95% uptime SLA. At the same time, the EKS console provides observability of your Kubernetes clusters so you can identify and resolve issues faster.

EKS Worker Nodes

The EKS worker nodes are rotated on an annual basis. EC2 instance provides on-demand security patches.
