Integrating ROSA Applications with AWS Services (CS221)

Learn to Integrate applications on ROSA with AWS services while keeping a good security posture.

Integrate applications on ROSA with AWS services while keeping a good security posture.

Course Description

  • Integrate applications deployed on ROSA with AWS services in a way that cluster administrators and platform engineers retain control of credentials and roles required by applications to access AWS services instead of exposing those credentials to application developers.
  • Note: This course is offered as a two day in person class, a three day virtual class or is self-paced. Durations may vary based on the delivery. For full course details, scheduling, and pricing, select your location then “get started” on the right hand menu.

Course Content Summary

  • Integrate with external container registries such as ECR and Quay.io to deploy applications from private image repositories
  • Configure storage classes to enable application access to different EBS volume types
  • Configure storage classes and security contexts to enable application access to shared EFS storage volumes
  • Configure pod identity using STS/IRSA to enable application access to AWS services such as database (Aurora), integration (SQS), and object storage (S3)
  • Provision AWS services for applications using the AWS Controllers for Kubernetes (ACK)
  • Federate and query application metrics (application workload monitoring) with Amazon Managed Prometheus Service
  • Aggregate and query structured application logs with Amazon CloudWatch
  • Configure custom domains and TLS certificates for secure public access to applications

Who Should Attend?

Target Audience

  • Primary: ROSA Administrators, Platform Engineers, Cloud Administrators, System Administrators and other infrastructure-related IT roles who are responsible for providing and supporting infrastructure for applications deployed on AWS
  • Secondary: Enterprise Architects, Site Reliability Engineers, DevOps Engineers, and other application-related IT roles who are responsible for designing infrastructure for applications deployed on AWS

What You'll Learn

Impact on the Organization

  • Red Hat OpenShift Service on AWS (ROSA) is a turnkey application platform that provides a managed Red Hat OpenShift service that runs natively on Amazon Web Services (AWS) to enable organizations to increase operational efficiency, refocus on innovation, and quickly build, deploy, and scale applications. Red Hat OpenShift is the hybrid cloud platform that brings operational consistency to on-premise and different cloud environments.
  • Organizations adopting ROSA are typically existing AWS customers with skills on using AWS services for a variety of business scenarios and need to integrate managed OpenShift clusters with their pre-existing AWS environments. These organizations are usually very security-conscious and require strong access controls and network security for all of their AWS services, including their ROSA clusters.

Impact on the Individual

  • After completing CS221, students can integrate applications deployed on a private ROSA cluster in a way that cluster administrators and platform engineers retain control of credentials and roles required by applications to access AWS services, instead of exposing those credentials to application developers.

Course Outline

Module 1: Deploy Applications From External Registries

  • Deploy applications on Red Hat OpenShift Service on AWS (ROSA) from private container image repositories in external centralized container image registries.

Module 2: Provide Amazon Storage Volumes for Applications

  • Configure Amazon Elastic Block Storage (EBS) or Amazon Elastic File System (EFS) volumes that meet the cost, performance, and sharing requirements of their applications.

Module 3: Configure Application Access to AWS Services

  • Configure applications for access to shared AWS services by using Kubernetes service accounts, and provision dedicated AWS services by using Kubernetes custom resources.

Module 4: OpenShift and AWS Application Observability

  • Configure ROSA clusters to forward application logs to Amazon CloudWatch and application metrics to Amazon Managed Service for Prometheus.

Module 5: Custom Domains for ROSA Applications

  • Expose applications to internet users with secure URLs by using human-readable DNS domains.
