Deployment 101

What is NOT one of the benefits of Microservice Architecture ?

• Technology flexibility

• Independently deployable

• Flexible Scaling

• Lower complexity

Which of the following best describe a container ?

• An OS used on software to imitate hardware

• A software package that contains applications for deployment across environments

• The center of a computer's OS

• A system software that controls system communication

Which types of hypervisor runs directly on hardware ?

• Type I

• Type 2

• Type 3

• Type 4

What is microservice ?

• A small program that represents discrete logic that executes within a well-defined boundary on dedicated hardware

• A design used primarily in functional programming and object-oriented programming

• A style of design for enterprise systems based on a loosely coupled component architecture

• A very small piece of code that never gets any bigger than 10 lines

Why do we need to implement CI ?

• Identify and fix bugs and security issues early

• To reduce hardware requirements for testing environments

• Reduce possibility of code conflict

• Ensure higher code quality

If a pipeline's stage fails, how can you check what went wrong ?

• Check the pipeline logs of failed stage(s) for error messages and details

• Manually inspect the source code

• Disable the failing stage and rerun the pipeline

• Run the pipeline again on a different environment

What is CD and which CD tool is used at TCB ?

• CD stands for Continuous Delivery - it is a manual process for integrating code changes. TCB uses ArgoCD.

• CD stands for Continuous Delivery - it is a technique for creating backups of code repositories. TCB uses Jenkins.

• CD stands for Continuous Delivery - it is a process that guarantees bug free software release. TCB uses ArgoCD.

• CD stands for Continuous Delivery - it extends CI by automating the release process up to a testing / staging environment. TCB uses ArgoCD.

Which aspects of an application can we monitor on ArgoCD ?

• Application events and error logs

• CPU and memory usage of individual containers

• Application's health status

• Sync status

What is Terraform ?

• A network performance monitoring tool

• A cloud operating system

• A tool for managing infrastructure as code (Infrastructure as Code)

• A web application programming tool

What happens if ArgoCD detects a mismatch between the desired state in Git and the live state of an application deployed on an EKS Cluster created by Terraform ?

• Terraform rebuilds the entire EKS Cluster through config file, and CI/CD flow start again

• ArgoCD automatically applies the Git configuration to the cluster to resolve the mismatch

• ArgoCD ignores the mismatch and waits for Jenkins to fix it

• Nexus revert the artifact to a previuos version
