Red Hat Certified Specialist in Building Resilient Microservices

Ex328: Red Hat Certified Specialist in Building Resilient Microservices, tests your skills and knowledge with regard to creating and managing a resilient mesh of microservices, using Red Hat OpenShift Container Platform and Red Hat OpenShift Service Mesh. The exam focuses on the basic skills required to use Red Hat Service Mesh to configure and manage the resilient operation of an application composed of several microservices with a persistent data store.

1. Deploy and configure applications on Service Mesh

Understand and work with Red Hat Openshift Service Mesh Custom Resources
Install sidecar manually in pod applications
Automatic sidecar injection using annotations
Understand the configuration of network policies (Mesh members, external services, etc.)

2. Routing and Traffic management

Be able to configure static and dynamic request routing to different versions of an application

3. Deployment release pattern strategies that Red Hat OpenShift Service Mesh

Providing more complex operational functionality
A/B testing
Canary releases

4. Configure and manage advanced routing Techniques

Traffic shifting migration within the mesh producing between different services A/B testing
Canary rollouts
Staged rollouts with percentage-based traffic splits
Dark launches for a selective group of users
Take profit of the traffic mirroring capabilities to bring changes to the microservices.
Shadowing launches copying the live traffic

5. Send the inbound and outbound traffic from and to the mesh

Managing the ingress and egress traffic control policies
Define and control gateway entry points into the mess for the incoming traffic allowing pass requests through the services
Enable controlled access to external publicly accessible services from within the istio cluster

6. Network resilience and the Fault Tolerance

Dynamically at runtime to ensure the failing nodes and prevent localized failures from cascading
Control the waiting time for replies defining timeouts
Enhance service availability specifying the number of request attempts with retry strategies
Limit for calls within a service and prevent access to an overloaded or failing host applying a circuit breaker mechanism
Specify the connection and ejection pool policies configuring the load balancing destination rules

7. Work and configure Service Mesh policy checks

Define enforcement features through policies, configure local and global rate limiting, and define access quotas
Enable and configure the authorization for denial and allow policies applied to a workload

8. Understand and configure the workload-to-workload Service Mesh

Provide service-to-service communication with secure naming authorization
Tunnel the service-to-service communication using mutual TLS communication.
Map the identity of the service name with secure naming
Define peer authentication policies to enforce the mutual TLS mode
Define the required end-user authentication policy check.

9. Understand and work with the fault injection

Inject timing failures producing delays to mimic increased network latency or overloaded services
Produce crash failures with error response injections and TCP connection failures
