+### Start VM - boto3
+```python
+import boto3
+
+client = boto3.client("ec2", region_name="ap-south-1")
+
+instance = client.run_instances(
+    ImageId="ami-00b9de22adf577ac9",
+    InstanceType="t2.nano",
+)
+```
+
+### Start VM - Terraform
+
+```python
+from cdktf_cdktf_provider_aws.provider import AwsProvider
+from cdktf_cdktf_provider_aws.instance import Instance
+
+AwsProvider(region="ap-south-1")
+Instance(
+    ami="ami-00b9de22adf577ac9",
+    instance_type="t2.micro",
+)
+```
+And run some magic commands
+
+```sh
+AwsProvider.synth()
+tofu plan
+tofu apply
+```
+Terraform shows us what it's going to do (truncated output)
+```terraform
+OpenTofu used the selected providers to generate the following execution
+plan. Resource actions are indicated with the following symbols:
+  + create
+
+OpenTofu will perform the following actions:
+
+  # aws_instance.compute will be created
+  + resource "aws_instance" "compute" {
+      + ami                                  = "ami-00b9de22adf577ac9"
+      + id                                   = (known after apply)
+      + instance_state                       = (known after apply)
+      + instance_type                        = "t2.micro"
+      + public_ip                            = (known after apply)
+    }
+
+Plan: 1 to add, 0 to change, 0 to destroy.
+```
+
+### Resize VM - boto3
+Resize however looks a little complicated. 
+
+Stop > Wait > Resize > Start
+```python
+client.stop_instances(InstanceIds=[instance.id])
+
+while client.describe_instances(InstanceIds=[instance.id]).state != "stopped":
+    time.sleep(1)
+
+client.modify_instance_attribute(
+    InstanceId=instance.id,
+    InstanceType={"Value": "t2.micro"},
+)
+
+client.start_instances(InstanceIds=[instance.id])
+```
+
+### Resize VM - Terraform
+Looks the same as before
+
+```python
+from cdktf_cdktf_provider_aws.provider import AwsProvider
+from cdktf_cdktf_provider_aws.instance import Instance
+
+AwsProvider(region="ap-south-1")
+Instance(
+    ami="ami-00b9de22adf577ac9",
+    instance_type="t2.nano",
+)
+```
+And the same magic incantations
+```sh
+AwsProvider.synth()
+tofu plan
+tofu apply
+```
+And we get the same plan we'd otherwise would've executed ourselves
+
+```terraform
+OpenTofu used the selected providers to generate the following execution
+plan. Resource actions are indicated with the following symbols:
+  ~ update in-place
+
+OpenTofu will perform the following actions:
+
+  # aws_instance.compute will be updated in-place
+  ~ resource "aws_instance" "compute" {
+        id                                   = "i-0c73da0cfdf81dcd5"
+      ~ instance_type                        = "t2.micro" -> "t2.nano"
+        tags                                 = {}
+        # (30 unchanged attributes hidden)
+
+        # (8 unchanged blocks hidden)
+    }
+
+Plan: 0 to add, 1 to change, 0 to destroy.
+```
+
+### Start VM - Terraform - DigitalOcean
+```python
+from cdktf_cdktf_provider_digitalocean.provider import DigitaloceanProvider
+from cdktf_cdktf_provider_digitalocean.droplet import Droplet
+
+DigitaloceanProvider()
+droplet = Droplet(
+    image="ubuntu-24-04-x64",
+    region="blr-1",
+    size="s-1vcpu-1gb",
+)
+```
