I need to move a couple of EC2 instances to Lightsail.
There are some ways of exporting Lightsail->EC2 using snapshot image but cannot find any info on how to do it the other way around EC2->Lightsail.
Is the migration EC2->Lightsail possible?
No, you can only migrate lightsail instances to EC2.
Try to create new Lightsail instance as per your requirement and then points IP address. last steps is terminate your old EC2 instance.

One of my AWS EC2 instances would be a better fit for Lightsail (and more cost-effective). Is there a way to create a Lightsail instance based from an EBS snapshot?
It seems that there is the ability to Export Amazon Lightsail snapshots to Amazon EC2, but I couldn't see any capability to go from EC2 to Lightsail.
Looks like you'll need to reload/reconfigure a Lightsail instance from scratch.
I created a WordPress app using Lightsail. It says it was created in Frankfurt Zone. However, I cannot see this instance in EC2 console. I want to create a Load Balancer for that app and add certificates, but I can't cause I don't see this instance on the list. Any ideas where can I find this Lightsail instance in EC2 console?
AWS Lightsail not shown in EC2 console, it's the main difference between the Lightsail and EC2, If you want to have more control on your EC2, so you should run EC2 instance instead of cheaper version Lightsail.
For more info about the Lighsail read the FAQ on the AWS website:
https://aws.amazon.com/lightsail/faq/
Also, you can use Lightsail load balancer instead of standard ELB on AWS, for more info read the following doc:

Thanks in advance....
we have RDS replication with multi-AZ option. Is there any way to replicate our AWS EC2 instances without using Auto-scaling option?
On the EC2 console listing running instances, select the instance you want to replicate and under Actions click Launch More Like This.
http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/launch-more-like-this.html
Yes, configure your EC2 instance exactly the way you want it to be. Stop the instance and create an AMI of this instance. Then launch as many EC2 instances as you want using the AMI. Each EC2 instance will be almost identical. There will be differences due to licensing, IP addressing, instance ID, etc.
This is the same technique that you would use with Auto Scaling Groups (e.g. new instances are launched from a specific AMI).
Another option is to use Launch More Like This from the EC2 Console. However, this feature does not clone your instance, only replicates some configuration details.
I'm using clamscan to check content on my elastic beanstalk instance, however, I'm having an issue where AWS either moves the instance to another IP and then clam scan is suddenly uninstalled. Is there a good way to prevent this from happening?
Thanks.

If AWS is "moving the instance to a new IP" what is actually happening is that Elastic Beanstalk is deleting your instance and spinning up an entirely new instance. I assume you manually configured ClamAV on your EB EC2 instance via SSH, which is the wrong way to configure EB instances. You even get a warning on the screen when you SSH into the instance telling you not to make any changes to the server because they won't be persisted across EB instances.
You have to use the appropriate methods provided by Elastic Beanstalk to configure your instances so that Elastic Beanstalk knows how to configure new instances when it automatically creates them for you. The method for doing this is documented here.
I'm studying RDS, and I have a question.
I'm reading in some places that rds relies on the ec2 infrastructure. But I don't understand why, what is the relation with rds and ec2?
I know that after we create an rds instance we can connect to rds instance from a ec2 instance, but what is the other relation?
For example, when we create a RDS instance we need to choose a db intance class, for example "db.t1.micro", but when we create an rds instance we dont create an ec2 instance...
So what I'm thinking is that maybe rds relies on ec2 infrastructure, because when we create an rds instance we are using the same ec2 infrastructure to create an instance but in this case for RDS? Is that it?
Yes you are correct, I think what they are really saying is that RDS instances run on the same infrastructure as the EC2 instances you spinup and use yourself.
When you start an RDS instance, it runs on an EC2 instance, but you have no access to that underlying instance it is controlled and managed by the RDS group/system.
