Explanation

The two offerings that DevOps tools can provide are: Integration between development and IT teams to achieve automation: DevOps tools facilitate collaboration and integration between development and IT operations teams. They provide a platform for automating processes, sharing information, and streamlining workflows, enabling faster and more efficient software development and deployment. Speeding up production consistency and speed by automating the Software Development Life Cycle (SDLC): DevOps tools automate various stages of the SDLC, including code compilation, testing, deployment, and monitoring. By automating these processes, DevOps tools help ensure consistency, reduce manual errors, and accelerate the release of software updates and new features. DevOps tools may also offer additional benefits such as improved security, reporting, and tracking metrics, but the primary offerings are integration and automation for faster and more efficient software delivery.

The two offerings which DevOps tool can provide are:

• Integrates between development and IT teams to achieve automation. DevOps tools enable collaboration between developers and operations teams by breaking down silos and streamlining workflows. DevOps tools also automate routine tasks and eliminate manual processes that can cause errors and delays.
• Speeds up production consistency and speed by automating SDLC. DevOps tools automate the software development lifecycle (SDLC) by enabling continuous integration and delivery (CI/CD) of software. DevOps tools also ensure consistency across different environments by using infrastructure as code (IaC) and configuration management techniques.

To create stages for an OKE deployment pipeline in OCI DevOps, you can add the following stages:

• Add a stage to deploy based on Blue-Green strategy or Canary strategy to OKE environment. A Blue-Green strategy is a deployment technique that involves creating two identical environments (blue and green) and switching traffic between them after testing. A Canary strategy is a deployment technique that involves releasing a new version of the application to a subset of users (canaries) and monitoring their feedback before rolling out to the rest of the users. You can use these strategies to reduce downtime, minimize risk, and improve user experience.
• Add a stage to apply the Kubernetes manifest to the Kubernetes cluster. A Kubernetes manifest is a YAML or JSON file that defines the desired state of your Kubernetes resources, such as pods, services, deployments, etc. You can use this stage to apply the manifest file to your OKE cluster using kubectl or helm commands.

Explanation

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.
