The cluster option that is the best fit for ensuring reliable operations of Kubernetes at scale while minimizing the operational overhead of managing the worker node infrastructure is using OCI OKE virtual nodes to eliminate worker node infrastructure management. OKE is a fully managed service that allows you to run and manage your Kubernetes cluster on OCI. A Kubernetes cluster consists of a control plane and a set of worker nodes that run your containerized applications. OKE provides a highly available and secure control plane that is managed by Oracle, while you are responsible for managing the worker node infrastructure. However, OKE also supports virtual nodes, which are serverless compute resources that are automatically provisioned and scaled by OCI based on your application workload demands. Virtual nodes eliminate the need for managing worker node infrastructure, such as security patches, updates, scaling, etc. Virtual nodes also offer a serverless Kubernetes experience, where you can focus on developing and deploying your applications without worrying about the underlying infrastructure.

Explanation

The group of OCI services that can help you get application insights is OCI Logging, Monitoring, and Application Performance Monitoring (APM). OCI Logging allows you to collect and analyze log data from your applications, infrastructure, and other resources. It helps you track and trouble-shoot issues by providing visibility into the performance and behavior of your applications. OCI Monitoring enables you to monitor the health, performance, and availability of your cloud resources, including your applications. It allows you to set up metrics, alarms, and notifications to proactively monitor and respond to any issues or anomalies. OCI Application Performance Monitoring (APM) is specifically designed to provide insights into the performance of your applications. It helps you identify and diagnose performance bottlenecks, track user experiences, and optimize the overall performance of your applications. By using OCI Logging, Monitoring, and APM together, you can gain comprehensive visibility into your cloud native applications and effectively monitor their performance and behavior.

The approach that should be used to trigger emails when a new file is created in an OCI Object Storage bucket is to create a rule in the OCI Events service that sends the bucket event to an OCI Notifications service topic configured with an email subscriber. The OCI Events service is a service that allows you to react to changes in your OCI resources by creating rules that match events of interest and trigger actions based on those events. The OCI Notifications service is a service that allows you to broadcast messages to distributed components through topics and subscriptions. By using these services together, you can achieve the following workflow:

• Create an OCI Notifications service topic and add an email subscriber with the customer’s email address.
• Create an OCI Events service rule that matches the Object Storage bucket event type “com.oraclecloud.objectstorage.createobject” and specifies the Notifications topic as the action.
• Whenever a new file is created in the Object Storage bucket, an event will be generated and matched by the rule, which will send a message to the Notifications topic.
• The Notifications topic will deliver the message to the email subscriber, which will trigger an email to the customer. Verified References: [Events - Oracle Cloud Infrastructure Developer Tools], [Notifications - Oracle Cloud Infrastructure Developer Tools]

The best practices that ABC Inc. should implement to incorporate DevSecOps into their DevOps process are:

• Follow established security guidelines, such as the OWASP DevSecOps guideline, during the development and testing process. The OWASP DevSecOps guideline is a set of recommendations and tools that help developers and testers integrate security into every stage of the software development lifecycle (SDLC). The guideline covers topics such as threat modeling, secure coding, code analysis, security testing, vulnerability management, etc.
• Perform regular scans for vulnerabilities and prioritize fixing them based on their severity. Vulnerability scanning is a process of identifying and assessing the security risks in your code, dependencies, images, containers, or infrastructure. You can use tools such as SonarQube, Sonatype Nexus IQ Server, or Twistlock to perform vulnerability scanning and generate reports with detailed information and remediation suggestions. You should also prioritize fixing the vulnerabilities based on their severity level and potential impact.
• Implement role-based access control and define roles and responsibilities for everyone involved in the development process. Role-based access control (RBAC) is a method of restricting access to resources based on the roles of the users or groups. You can use RBAC to enforce the principle of least privilege, which means granting only the minimum level of access required for each user or group to perform their tasks. You should also define clear roles and responsibilities for everyone involved in the development process, such as developers, testers, operations staff, security staff, etc., and assign them appropriate permissions and policies.
