Amazon Web Services (AWS) is retiring its flagship cloud computing infrastructure services, Elastic Compute Cloud, known as EC2-Classic. Current users of EC2-Classic will have about a year to make the transition to Amazon Virtual Private Cloud (VPC), and the company wants to make that transition as painless as possible.

“EC2-Classic has served us well,” said Jeff Barr, chief evangelist for AWS, in a blog post. “Rest assured that we are going to make this as smooth and as non-disruptive as possible,” Barr said in his post. “We are not planning to disrupt any workloads, and we are giving you plenty of lead time, so that you can plan, test, and perform your migration.”

AWS is putting its resources behind that promise with migration tools and support, including the AWS Application Migration Service (MGN) and the AWSSupport-MigrateEC2ClassicToVPC runbook. The MGN uses block-level replication and runs on multiple versions of Linux and Windows. (The first 90 days of replication are free for each server migrated, the company says.) The runbook supports simple, instance-level migration.

AWS does plan to disable EC2-Classic on Oct. 31, 2021, for accounts that don’t currently use the service, the company says, and it will stop selling reserved instances for the network environment.
