In order to effectively test your cloud-native applications, you might utilize separate environments
(development, testing, staging, production, etc.). Which Oracle Cloud Infrastructure (OC1) service can you use
to create and manage your infrastructure?
Your organization has deployed their e-commerce application on Oracle Container Engine for Kubernetes
(OKE) and they are using the Oracle Cloud Infrastructure Registry (OCIR) service as their Docker image
repository. They have deployed the OKE cluster using the 'custom create' option, and their Virtual Cloud
Network (VCN) has three public subnets with associated Route Tables, Security Lists, and Internet Gateway.
However, their application containers are failing to deploy. On investigation, they discover that the images are
not being pulled from the designated OCIR repository, even though the YAML configuration has the correct
path to the images. What is a valid concern here that needs to be further investigated?
You have two microservices, A and B running in production. Service A relies on APIs from service B. You
want to test changes to service A without deploying all of its dependencies, which includes service B. Which
approach should you take to test service A?
