Amazon Web Services to retire its EC2-Classic Networking:
AWS Cloud customers using the old EC2-Classic resources for powering apps need to review their accounts now.
Amazon Web Services (AWS) has announced that it will be going to shut down one of its oldest cloud computing infrastructure services, EC2-Classic. and warning its customers who are still using the service to review their accounts and move off the service to avoid application downtime.
AWS evangelist Jeff Barr wrote, “EC2-Classic has served us well, but we’re going to give it a gold watch and a well-deserved sendoff.” EC2-Classic has been launched with the release of Amazon EC2, but later amazon stopped the use of this service for accounts created after April 2013, at this point, it required users to launch instances of EC2 in a virtual private cloud (VPC) – logically separated section AWS.

Deadlines coming up for all EC2-Classic users:
All the EC2-Classic instances run in a flat and single network that is shared with other users and customers. To communicate with the resources of AWS in a VPC, EC2-Classic required public IP addresses or tunneling made available at the time.
Jeff Barr says there are some deadlines coming up in the near months for the business which are still on EC2-Classic, the process will be gradual. He notes, “We are going to make this process non-disruptive and as smooth as possible. We are not planning to disrupt any workloads and we are giving you plenty of lead time so that you can test, plan and perform your migration from EC2-Classic”.
Key Dates to note all EC2-Classic users:
Key Dates to note for all AWS users are October 30, 2021, and August 15, 2022.
AWS will first disable the instances of EC2-Classic for accounts that have no active EC2-Classic resources in the region On October 30. and from that date, 1-year and 3-year Reserved Instances for EC2-Classic won’t be available to purchase from AWS.
And by the date, August 15, 2022, AWS rechecks from all their users to confirm their migrations, or else migrations will be done. and after that, all resources of EC2-Classic will be removed from AWS accounts.
The customers of EC2-Classic should note that disabling the instance in a region is meant to be a “one-way door”, but Barr says “users can re-enable EC2-Classic for a region by contacting AWS Support.
