Challenge - 5 Problems

Why does independent deployment improve system reliability?

In a microservices architecture, why does deploying services independently help improve overall system reliability?

A Because it requires all services to be deployed in a single package.

B Because all services share the same database, making deployment faster.

C Because a failure in one service does not require stopping or redeploying the entire system.

D Because independent deployment forces all services to restart simultaneously.

💡 Hint

Think about how isolating changes affects the rest of the system.

Independent deployment allows each microservice to be updated or fixed without affecting others, reducing downtime and risk.

❓ Architecture

intermediate

Which deployment strategy best supports independent deployment?

Which deployment approach best enables independent deployment in microservices?

A Deploying all microservices together in a single monolithic application.

B Deploying microservices by bundling them into one large executable.

C Deploying microservices only during scheduled full system downtime.

D Deploying each microservice as a separate container or unit.

💡 Hint

Consider how isolation of services affects deployment.

Containers or separate units allow each microservice to be deployed and scaled independently.

❓ scaling

How does independent deployment affect scaling microservices?

What is the impact of independent deployment on scaling microservices efficiently?

A It allows scaling only the services that need more resources without affecting others.

B It forces scaling all services together regardless of load.

C It prevents scaling because services are tightly coupled.

D It requires scaling the entire system even if only one service needs it.

💡 Hint

Think about resource usage and demand per service.

Independent deployment lets you allocate resources to only the microservices that require it, saving cost and improving performance.

❓ tradeoff

advanced

What is a tradeoff of independent deployment in microservices?

While independent deployment has many advantages, what is a common tradeoff or challenge it introduces?

A It increases complexity in managing multiple deployment pipelines and service versions.

B It reduces fault isolation between services.

C It eliminates the need for service monitoring.

D It forces all services to share the same runtime environment.

💡 Hint

Consider what managing many independent services requires.

Managing many independently deployed services requires more sophisticated automation and version control.

Estimate deployment frequency impact with independent deployment

If a system has 20 microservices deployed independently, and each service is updated on average twice a week, approximately how many deployments occur per week?

A 20 deployments per week

B 40 deployments per week

C 10 deployments per week

D 2 deployments per week

💡 Hint

Multiply the number of services by updates per service.

20 services × 2 updates each = 40 deployments weekly.
