What is the difference between Amazon EC and Amazon lightsail
"Amazon lightsail is a option limited version of amazon ec. It does run in amazon ec, but gives you less configuration possibilities and it is cheaper than amazon ec.
Here is the technical explanation from an user called Michael in stack overflow
Testing¹ reveals that Lightsail instances in fact are EC2 instances, from the t2 class of burstable instances.
EC2, of course, has many more instance families and classes other than the t2, almost all of which are more "powerful" (or better equipped for certain tasks) than these, but also much more expensive. But for meaningful comparisons, the 512 MiB Lightsail instance appears to be completely equivalent in specifications to the similarly-priced t2.nano, the 1GiB is a t2.micro, the 2 GiB is a t2.small, etc.
Lightsail is a lightweight, simplified product offering -- hard disks are fixed size EBS SSD volumes, instances are still billable when stopped, security group rules are much less flexible, and only a very limited subset of EC2 features and options are accessible.
It also has a dramatically simplified console, and even though the machines run in EC2, you can't see them in the EC2 section of the AWS console. The instances run in a special VPC, but this aspect is also provisioned automatically, and invisible in the console. Lightsail supports optionally peering this hidden VPC with your default VPC in the same AWS region, allowing Lightsail instances to access services like EC2 and RDS in the default VPC within the same AWS account.²
Bandwidth is unlimited, but of course free bandwidth is not -- however, Lightsail instances do include a significant monthly bandwidth allowance before any bandwidth-related charges apply.³ Lightsail also has a simplified interface to Route 53 with limited functionality.
But if those sound like drawbacks, they aren't. The point of Lightsail seems to be simplicity. The flexibility of EC2 (and much of AWS) leads inevitably to complexity. The target market for Lightsail appears to be those who "just want a simple VPS" without having to navigate the myriad options available in AWS services like EC2, EBS, VPC, and Route 53. There is virtually no learning curve, here. You don't even technically need to know how to use SSH with a private key -- the Lightsail console even has a built-in SSH client -- but there is no requirement that you use it. You can access these instances normally, with a standard SSH client.
¹Lightsail instances, just like "regular" EC2 (VPC and Classic) instances, have access to the instance metadata service, which allows an instance to discover things about itself, such as its instance type and availability zone. Lightsail instances are identified in the instance metadata as t2 machines.
²The Lightsail docs are not explicit about the fact that peering only works with your Default VPC, but this appears to be the case. If your AWS account was created in 2013 or before, then you may not actually have a VPC with the "Default VPC" designation. This can be resolved by submitting a support request, as I explained in Can't establish VPC peering connection from Amazon Lightsail (at Server Fault).
³The bandwidth allowance applies to both inbound and outbound traffic; after this total amount of traffic is exceeded, inbound traffic continues to be free, but outbound traffic becomes billable. See "What does data transfer cost?" in the Lightsail FAQ"
- Create a lightsail account.
2. Once you have the instance create a static ip.
Follow these steps to create a new static IP address and attach it to an instance in Lightsail.
Sign in to the Lightsail console at https://lightsail.aws.amazon.com/.
On the Lightsail home page, choose Networking.
Choose Create static IP.
Select the AWS Region where you want to create your static IP.
Choose the Lightsail resource to which you want to attach the static IP.
Enter a name for your static IP.
Must be unique within each AWS Region in your Lightsail account.
Must contain 2 to 255 characters.
Must start and end with an alphanumeric character or number.
Can include alphanumeric characters, numbers, periods, dashes, and underscores.
Now when you go to the home page, you see a static IP address that you can manage.
Also, on the Networking tab of your instance's management page, you'll see a blue pushpin next to your public IP address. This indicates that the IP address is now static.
3. Point the ip to the domain with name servers
