What is the difference between blue/green and canary deployment strategies?

• A.In blue/green, application Is deployed In minor increments to a select group of people. In canary, both old and new applications are simultaneously in production.
• B.In blue/green, both old and new applications are in production at the same time. In canary, application is deployed Incrementally to a select group of people.
• C.In blue/green, current applications are slowly replaced with new ones. In < MW y, Application ll deployed incrementally to a select group of people.
• D.In blue/green, current applications are slowly replaced with new ones. In canary, both old and new applications are In production at the same time.

Correct Answer: B

Explanation
Blue-green deployment is a technique that reduces downtime and risk by running two identical production environments called Blue and Green. At any time, only one of the environments is live, with the live environment serving all production traffic. For this example, Blue is currently live and Green is idle.

Canary deployments are a pattern for rolling out releases to a subset of users or servers. The idea is to first deploy the change to a small subset of servers, test it, and then roll the change out to the rest of the servers. ...
Canaries were once regularly used in coal mining as an early warning system.

Which two "Action Type" options are NOT available in an Oracle Cloud Infrastructure (OCI) Events rule definition?

• A.Notifications
• B.Functions
• C.Streaming
• D.Email
• E.Slack

Correct Answer: D,E

Explanation
Overview ofEvents
Oracle Cloud Infrastructure Events enables you to create automation based on the state changes of resources throughout your tenancy. Use Events to allow your development teams to automatically respond when a resource changes its state.
Event Rules must also specify an action to trigger when the filter finds a matching event. Actions are responses you define for event matches. You set up select Oracle Cloud Infrastructure services that the Events service has established as actions. The resources forthese services act as destinations for matching events.
When the filter in the rule finds a match, the Events service delivers the matching event to one or more of the destinations you identified in the rule. The destination service that receives the eventthen processes the event in whatever manner you defined. This delivery provides the automation in your environment.
You can only deliver events to certain Oracle Cloud Infrastructure services with a rule. Use the following services to create actions:
Notifications
Streaming
Functions
