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

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.

Next, choose apply.

Now, you can able to see the new instance for the instance under the instance type

tab

Now you can start the instance and it will start with the new m4.large CPU and

RAM configuration.
