20 Questions
Why are containers meant to be immutable?
To rebuild and redeploy the whole image instead of patching live containers.
What is the advantage of patching images in the container registry instead of patching live containers?
Rolling out fully patched container images as one unit.
How does using containers help in avoiding downtime while patching newly discovered vulnerabilities?
By rolling out patched images with blue/green deployments.
What is the benefit of having containers that provide content addressability?
To identify susceptible versions and apply patches easily.
How do containers help in making the patch rollout process similar to the code rollout process?
By enabling monitoring, canarying, and testing during the rollout.
What approach suggests gradually rolling out changes with instrumentation for canarying?
Staged roll out
Why is it important to keep dependencies up to date?
To make the system less susceptible to new vulnerabilities
Which strategy is suggested to enable easy roll out of changes with minimal friction?
Updating dependencies and rebuilding frequently
Why is a 'slow and steady' approach to rollout recommended?
To avoid widespread downtime or data loss
Which practice involves no change in behavior when a specific feature is turned off?
Staged roll out
What strategy can help reduce the need for ad hoc patching of containers?
Monitor the age of containers and redeploy regularly
What is a recommended practice to avoid redeploying older, unpatched container images in production?
Enforce deploying only recently built containers
How does using a microservices architecture help in managing potential bottlenecks between services?
By splitting workloads into smaller units
What advantage does independently scaling, load balancing, and performing rollouts in each microservice provide?
More flexibility to make infrastructure changes
How do microservices facilitate limited or zero trust networking?
Not inherently trusting a service just because it's in the same network
Why is it recommended to split one large release into many smaller ones?
To make it easier to understand what changed and pinpoint potential issues.
What is the advantage of frequently rebuilding and redeploying your environment?
It allows for emergency rollouts to pick up the latest changes.
How does automated testing contribute to frequent releases?
It reduces the need for manual validation of code changes.
Why is backporting fixes to supported versions important?
To avoid merging with a backlog of changes.
What is the significance of ensuring dependencies are up to date?
It enables the direct application of critical patches.
Test your knowledge on how large open source projects manage architecture decisions for making changes easier and implementing security vulnerability response plans. Explore the process of backporting critical security patches and the importance of keeping dependencies up to date.
