I have some Amazon Lightsail Instance, a group of small server used as a load balancer for our SMTP cluster. Amazon Lightsail in short equivalent with DigitalOcean Droplet or Linode Node or a let say it is a simple set of VM comparing to Amazon EC2.
As I started with a basic requirement for an SMTP server, I chose a low-end spec with 1 vCPU and 1 GB RAM for US$ 5/month. Initially, everything went as smooth as expected but it has a slow performance after some plugins added to the server.
Although there are several choices to improve its performance, I decided to upgrade the Lightsail VM into a higher plan. Linode, DigitalOcean and Vultr have this option as well but I don’t see any similar option on the Lightsail until finding it in the Snapshot menu on VM dashboard.
-
On the home page, choose the instance you want to manage or simply click on an instance
-
Choose Snapshots.
-
Choose Create a new instance from the snapshot menu. We must create a snapshot before use it as a base instance to be deployed
-
On the Create an instance from a snapshot page, we have a few optional settings to decide on at the top. We can accept all the defaults and move on to the next step or choose an appropriate option.
-
Choose the plan for a new instance. At this point, we can choose to create a larger bundle size (as we cannot create a smaller plan).
-
Give our instance and disks new, unique names, and then choose Create.
A little bit different with Linode approach and quite similar to DigitalOcean snapshot feature but DigitalOcean has a different menu for upgrading its droplet.
