Creating and managing a custom security group

{: #creating-and-managing-a-custom-security-group}

In this tutorial learn how to create, assign instances to, and edit a custom {{site.data.keyword.cloud}} security group. {: shortdesc}

What you'll need

{: #what-you-ll-need-3}

For this example, the following objects and items are used:

Resource Name Operating System Type Location/DC IP/Subnet
Not Applicable/Any 10.0.0.0/16
allow_icmp Not Applicable Security Group Not Applicable/Any 0.0.0.0/0
allow_ssh Not Applicable Security Group Not Applicable/Any 0.0.0.0/0
jpmongevsi2.testing.com Ubuntu 16.04 Virtual server instance Dallas 10 Pod 01 10.0.0.21
jpmongevsi4.testing.com Ubuntu 16.04 Virtual server instance Dallas 10 Pod 01 10.0.2.219

Note that this tutorial uses a CPA private network/account. However, for practical purposes security groups behave the same way in both CPA accounts and regular accounts. Subnets 10.0.0.0/24 and 10.0.2.0/24 belong to the same CPA private network, which would be the equivalent of having a regular account with two or more virtual server instances that are connected to the same private subnet/VLAN.
