AWS SECURITY GROUPS
SECURITY GROUPS:
A security group acts as a virtual firewall that controls the traffic for one
or more instances.
When you launch an instance, you associate one or more security groups
with the instance.
You add rules to each security group that allow traffic to or from its
associated instances.
You can modify the rules for a security group at any time; the new rules
are automatically applied to all instances that are associated with the
security group.
Click on Security groups section under NETWORK & SECURITY from
the left pane.
CHANGING OR ADDING SECURITY GROUPS TO YOUR EXISTING INSTANCES:
Click the instance from Instance tab and select the instance, then click on Actions.
Click on Security and select Change security Groups
By Clicking on ADD SECURITY GROUP , You can change the security group
Click on save option to change and save your security group.
AWS Changing Instance-Types
Amazon EC2 provides a wide selection of instance types optimized to fit different
use cases. Instance types comprise varying combinations of CPU, memory,
storage, and networking capacity and give you the flexibility to choose the
appropriate mix of resources for your applications. Each instance type includes one
or more instance sizes, allowing you to scale your resources to the requirements of
your target workload.
We have few types of the instances available, those categorized in to the following.
General Purpose
Compute Optimized
Memory Optimized
Accelerated Computing
Storage Optimized
You can check the full list of the instance types from the below URL.

CHANGING INSTANCE TYPES
We can change instance types from one type to another with few clicks, but there
is down time involved here because we must shut down the instance to change
instance type.
To change the instance type, select your instance and go to actions then instance
state then stop.
Once the instance has stopped, make sure you select the instance and go to Actions
tab, expand Instance Settings, then choose Change Instance Type.
Next, Change instance type wizard will open, choose the new instance type from
instance type drop down list.
