Let’s return to the summer season of 2006 and the launch of EC2. We began with one circumstances type (the age-old m1.small), security groups, and the age-old United States East (N. Virginia) Area. The EC2-Classic network design was flat, with public IP addresses that were appointed at launch time.
Our preliminary consumers saw the worth right now and began to put EC2 to utilize in various methods. We hosted website, supported the launch of Justin.TV, and assisted Animoto to scale to a then-amazing 3400 circumstances when their Facebook app went viral.
A few of the early improvements to EC2 concentrated on networking. For instance, we included Elastic IP addresses in early 2008 so that addresses might be long-lived and connected with various circumstances in time if essential. After that we included Car Scaling, Load Balancing, and CloudWatch to assist you to construct extremely scalable applications.
Early consumers wished to link their EC2 circumstances to their business networks, workout extra control over IP address varies, and to build more advanced network geographies. We introduced Amazon Virtual Private Cloud in 2009, and in 2013 we made the VPC design basically transparent with Virtual Personal Clouds for Everybody.
EC2-Classic has actually served us well, however we’re going to provide it a gold watch and a well-deserved sendoff! This post will inform you what you require to understand, what you require to do, and when you require to do it.
Prior to I dive in, felt confident that we are going to make this as smooth and as non-disruptive as possible. We are not preparing to interrupt any work and we are offering you a lot of preparation so that you can prepare, test, and perform your migration. In addition to this post, we have tools, documents, and individuals that are all developed to assist.
We are currently alerting the staying EC2-Classic consumers through their account groups, and will quickly begin to provide notifications in the Personal Health Control Panel. Here are the essential dates for your calendar:
- All AWS accounts developed after December 4, 2013 are currently VPC-only, unless EC2-Classic was made it possible for as an outcome of an assistance demand.
- On October 30, 2021 we will disable EC2-Classic in Areas for AWS accounts that have no active EC2-Classic resources in the Area, as noted below. We will likewise stop offering 1-year and 3-year Scheduled Circumstances for EC2-Classic.
- On August 15, 2022 we anticipate all migrations to be total, without any staying EC2-Classic resources present in any AWS account.
Once Again, we do not prepare to interrupt any work and will do our finest to assist you to satisfy these dates.
In order to completely move from EC2-Classic to VPC, you require to discover, take a look at, and move all of the list below resources:

You might require to develop (or re-create, if you erased it) the default VPC for your account. To find out how to do this, check out Producing a Default VPC.
Sometimes you will have the ability to customize the existing resources; in others you will require to develop brand-new and comparable resources in a VPC.
Finding EC2-Classic Resources
Utilize the EC2 Classic Resource Finder script to discover all of the EC2-Classic resources in your account. You can run this straight in a single AWS account, or you can utilize the consisted of
multi-account-wrapper to run it versus each account of an AWS Company. The Resource Finder check outs each AWS Area, searches for particular resources, and creates a set of CSV files. Here’s the very first part of the output from my run:
The script takes a couple of minutes to run. I examine the list of CSV files to get a sense of just how much work I require to do:
And after that I have a look inside to read more:
Ends Up that I have some stopped OpsWorks Stacks that I can either move or erase:
Here’s a summary of the migration tools that you can utilize to move your AWS resources:

Assistance Automation Workflow— This workflow supports basic, instance-level migration. It transforms the source circumstances to an AMI, develops mirrors of the security groups, and releases brand-new circumstances in the location VPC.
After you have actually moved all of the resources within a specific area, you can disable EC2-Classic by producing an assistance case. You can do this if you wish to prevent unintentionally producing brand-new EC2-Classic resources in the area, however it is certainly not needed.
Disabling EC2-Classic in an area is planned to be a one-way door, however you can call AWS Assistance if you run it and after that discover that you require to re-enable EC2-Classic for an area. Make sure to run the Resource Finder that discussed earlier and make certain that you have actually not left any resources behind. These resources will continue to run and to accumulate charges even after the account status has actually been altered.
IP Address Migration— If you are moving an EC2 circumstances and any Elastic IP addresses connected with the circumstances, you can utilize
move-address-to-vpc then connect the Elastic IP to the moved circumstances. This will enable you to continue to reference the circumstances by the initial DNS name.
Traditional Load Balancers— If you prepare to move a Timeless Load Balancer and require to protect the initial DNS names, please contact AWS Assistance or your AWS account group.

Nevertheless, lots of more recent circumstances types are readily available just in VPC, and you might wish to think about an upgrade as part of your general migration strategy. Here’s a map to get you began:
Depend On United States
