What is AB deployment?
A/B deployments. The A/B deployment strategy lets you try a new version of the application in a limited way in the production environment. You can specify that the production version gets most of the user requests while a limited fraction of requests go to the new version.
What is Redblack test?
Red-Black deployment is a release technique that reduces downtime and risk by running two identical production environments called Red and Black. At any time, only one of the environments is live, with the live environment serving all production traffic.
How does Bluegreen deployment work?
A blue/green deployment is a deployment strategy in which you create two separate, but identical environments. One environment (blue) is running the current application version and one environment (green) is running the new application version.
How do you make white with red green and blue numbers?
#FFFFFF means full FF amounts of Red, Green, and Blue. The result is WHITE. #FFEFD5 has high values for all colors, giving a light result: PAPAYAWHIP.
What is a canary deployment?
A canary deployment is a deployment strategy that releases an application or service incrementally to a subset of users. All infrastructure in a target environment is updated in small phases (e.g: 2%, 25%, 75%, 100%).
Why is it called Canary release?
“Canary releases” get their name from an old coal mining tactic. Miners would release canaries into coal mines in an attempt to gauge the amount of toxic gases present. If the canary survived, well, things were safe.
Why is it called blue green?
They finally settled on using colors instead, which didn’t have a natural order. Thus, they planned names like blue, green, or orange (they avoided red because it implied danger). In the end, it turned out they only needed two environments. And so the term blue-green was coined.
What’s the difference between a blue green deployment and a rolling deployment?
The difference between the rolling and blue/green strategies is that in a rolling strategy, the infrastructure is not in a separate network or environment like in blue/green. Like in-place deployments, rolling deployments suffer from a risky rollback if issues occur during deployment.
What does cyan and red make?
If you mix a cyan light with a red light you get a white light. If you mix a cyan paint and a red paint you get a black paint.

What is shadow deployment?
Shadow Deployment That is, requests are sent to the current version and the new version, but all responses come only from the existing stable version. In this way, you can monitor the latest version under load without any possibility of customer impact. This strategy is sometimes called a mirrored canary deployment.
What is dark launching in Devops?
Dark launching is a process that allows you to release production-ready software features to a small group of users while hiding them from the rest of the user base prior to a full release. A dark launch can also include deploying code to a production environment but without exposing it to any production traffic.
