One of the ways that OCI DevOps deployment pipelines reduce risk and complexity of production applications is by reducing change-driven errors introduced by manual deployments. A deployment pipeline is a sequence of stages that automates the delivery of software from source code to production. By using a deployment pipeline, you can eliminate human errors, enforce quality checks, and ensure consistency across different environments. A deployment pipeline also enables faster feedback loops, easier rollback, and improved traceability of changes.

The two changes to infrastructure with the Oracle Cloud Infrastructure (OCI) Provider for Terraform that will not result in any resources being destroyed or provisioned are: Adding a CIDR block to a VCN: This change does not affect any existing resources. It simply expands the IP ad-dress range of the VCN, allowing for the creation of additional subnets within the VCN. Adding a subnet to a VCN: Similar to adding a CIDR block, adding a subnet to a VCN does not affect any existing resources. It defines a new subnet within the VCN's IP address range, allowing for the al-location of resources to that subnet. Changing the image OCID of a compute instance, changing the shape of a compute instance, and changing the Display Name of a compute instance can potentially result in resource destruction and provisioning. These changes may require the creation of new in-stances, reconfiguration of existing instances, or termination of existing instances, depending on the specifics of the changes.

The two approaches that can be used to build the e-commerce website and achieve deployment in-dependence, easier technology upgrades, and resiliency to architecture changes are: Implement each module as an independent service/process: This approach is aligned with the microservices architecture, where each module or functionality is developed and deployed as a separate service. This al-lows for independent updates, replacements, or deletions of specific modules without disrupting the rest of the application. It provides flexibility, scalability, and easier technology upgrades by enabling the use of different technologies and frameworks for different services. Use microservices architec-ture: Microservices architecture involves breaking down the application into smaller, loosely coupled services that communicate with each other through APIs. This architecture promotes independent deployment of services, making it easier to update or modify specific services without affecting the entire application. It allows for better scalability, fault isolation, and resiliency to architecture changes. The monolithic approach, where the entire application is built as a single unit, is not suitable for achieving the mentioned goals. It can lead to challenges in deployment independence, technology upgrades, and adaptability to newer technologies.

To rollback to version 1 of a secret that has been rotated once, you need to do the following:

From the version 1 menu, select ''Promote to Current''. This will change the status of version 1 from Previous to Current, and change the status of version 2 from Current to Previous. This means that version 1 will be used as the current key version for encrypting and decrypting secrets.

Optionally, you can also delete version 2 if you no longer need it. From the version 2 menu, select ''Delete''. This will change the status of version 2 from Previous to Deleted. You can also restore or destroy deleted versions if needed. Verified Reference: [Rotating Secrets - Oracle Cloud Infrastructure Vault], [Managing Secret Versions - Oracle Cloud Infrastructure Vault]

The correct approach to upgrade an Oracle Container Engine for Kubernetes (OKE) cluster to a newer version of Kubernetes is to first upgrade the control plane and then upgrade the node pools. Here are the steps to follow: Upgrade the control plane: Initiate the upgrade process for the control plane using the OCI Console, CLI, or API. This upgrade will update the Kubernetes control plane components running in the master nodes of the cluster. Upgrade the node pools: After the control plane upgrade is completed, you can proceed to upgrade the node pools. A node pool is a set of worker nodes within the cluster. You can upgrade the node pools one at a time or simultaneously, depending on your requirements and cluster configuration. By following this approach, you ensure that the control plane is upgraded first, which ensures compatibility and stability with the new version of Kubernetes. Afterward, you can upgrade the node pools to ensure all worker nodes are running the latest version of Kubernetes. It is important to note that before performing any upgrades, it is recommended to review the release notes and upgrade documentation provided by Oracle for any specific instructions or considerations related to the version you are upgrading to.
