Deployment methods

Deployment into production has its pains. We take a lot of precautions while deploying into production. We introduce lots of testing on lower environments so that most of the bugs and performance problems are taken care of early on. But we are still nervous when deploying into production, as we are never 100 percent sure whether the deployed version will work perfectly fine. If we are using deployment techniques, then we minimize the deployment failure substantially. There are varieties of deployment technique, but canary and blue-green are the most popular ones. We will look at examples of both deployment techniques for AWS Lambda.
