Elastic Beanstalk Deploymemt Modes

All at once(deploy all in one go)

• fastest, but instances aren't available to serve traffic for a bit(downtime)
• Great for quick iterations in development environment
• 가장 빠르다. 잠깐 서버 다운타임이 생긴다.
  

Rolling

• update a few instances at a time(bucket), and then move onto the next bucket once the first bucket is healthy
• Application is running below capacity
• can set the bucket size
• Application is running both versions simultaneously
• no additional cost
• long deployment
  

Rolling with additional batches

• like rolling, but spins up new instances to move the batch(so that the old application is still available)
  

Immutable

• spins up new instances in a new ASG, deploys version to these instances, and then swaps all the instances when everyting is healty
