A SaaS company runs a stateless web application on a fleet of 20 virtual machines behind a load balancer. The team needs to update the application to a new version without taking the service offline, and they want to minimize the number of additional resources required. Which deployment approach should they choose?

Rolling deployment, updating a few VMs at a time while keeping the rest serving traffic

In-place release by stopping all VMs and updating them simultaneously

Canary deployment by routing 10% of traffic to a new VM

Blue-green deployment by provisioning a second set of 20 VMs

A financial services firm must update its customer portal with zero downtime. The compliance team requires an immediate rollback to the previous version if any critical transaction errors are detected after the update. The infrastructure budget allows running two full production environments. Which deployment strategy best meets these requirements?

Canary deployment to a small subset of users

Blue-green deployment with a router-level switch

In-place release with a backup of the previous build

Rolling deployment across the existing servers

An organization is implementing a canary deployment for a new application version. Which action is characteristic of this strategy?

Directing all user traffic to the new version immediately

Replacing the entire environment with a new one in a single step

Gradually increasing the percentage of traffic sent to the new version

Updating servers one by one without traffic splitting

A small startup runs a monolithic application on a single, low-cost production server. The team has a very limited budget and cannot afford to provision additional infrastructure. They need to deploy a new version of the application, and a brief maintenance window of a few minutes is acceptable. Which deployment technique is most appropriate?

In-place release by stopping the service, updating the application, and restarting it

Canary deployment by running two versions on the same server

Rolling deployment across multiple instances of the application

Blue-green deployment with a second server
