Optimizing Deployment Time on AWS Elastic Beanstalk
Question
You have been instructed to manage the deployments of an application onto Elastic Beanstalk.
Since this is just a development environment, you have been told to ensure that the least amount of time is taken for each deployment.
Which of the following deployment mechanism would you consider based on this requirement?

A. B. C. D.Answer - A.
Below is the screenshot of the deployment options.
The ‘All at once' is the least deployment option.
Based on the above screenshot, all the other options become invalid.

When deploying an application onto Elastic Beanstalk, there are several deployment mechanisms available that can be used based on the specific requirements of the application and deployment process.
The four deployment mechanisms available are:
A. All at once: This deployment mechanism deploys the new version of the application to all instances in the environment at the same time. It is the fastest deployment option since all instances are updated simultaneously. However, this option can result in downtime as all instances are unavailable during the deployment process.
B. Rolling: This deployment mechanism updates a percentage of the instances in the environment at a time. After the initial batch is updated, traffic is redirected to the updated instances, and the process repeats until all instances have been updated. This option minimizes downtime as traffic is redirected to the updated instances, but it can take longer than the "all at once" option since the update process is spread out over a longer period of time.
C. Immutable: This deployment mechanism deploys a new version of the application to a new set of instances and then swaps the new instances with the old instances. This option results in zero downtime as the new instances are running before the old instances are terminated. However, this option can take longer than the other options since new instances must be launched and configured before the swap can occur.
D. Rolling with additional batch: This deployment mechanism is similar to the "rolling" option, but it deploys an additional batch of instances before the initial batch is updated. This option reduces downtime by ensuring that there are always enough instances available to handle traffic. However, this option can take longer than the "rolling" option since there are more instances to update.
Based on the requirement to minimize the time taken for each deployment in a development environment, the "All at once" deployment mechanism would be the best option since it is the fastest deployment option available. However, it is important to note that this option can result in downtime during the deployment process, so it should be used with caution in production environments.
