Difference between cloud discovery and IP based discovery?

What is the difference between discovering CI with the help of cloud discovery vs IP-based discovery? I notice even after creating a service account, we still need to give credentials to search the VMs in the cloud.

Hello --

  Generally speaking, there are 2 types of discovery needed to get the 'full picture' of a virtual machine/device.   

1st cloud discovery gets the cloud-based meta data, such a network definitions (VPC details in AWS world), data centers, etc.   But this does not get the running details of the OS (processes, installed software, IP connections between nodes, etc.)... that's actually impossible in some cases if you think about it.  When a VM is shut OFF, there are no running processes, no IP connections between devices that are not running etc.. but the cloud disco can find the definition of the VM and its components (the config that is managed within the AWS console for example).  

2nd discovery is IP-based disco that is only possible when the VM machine is on, active and accessible.  When this 2nd disco runs, it can uncover IP connections, installed software, etc.. i.e. all the details that can be found only when the machine is up and running.

Same principal applies to all cloud and virtual environments.  The 1st disco is getting the definition of the virtual world and its hosting infrastructure, while the 2nd disco interrogates the running machines.

Hope this helps some?

Hello Dave,

 

If we have both the discovery module running, does it create 2 CI entries in CMDB. 

The situation i am in there are multiple entries been created. To be specific by example

1) Windows Server

2) VM machine instance

 

What can i do to have only CI been created in CMDB table

Hello 

Cloud Based Discovery:- Cloud discovery helps enterprises comprehensively identify all cloud instances spanning applications, databases, containers and related services running at a given point in time. ... It helps security and operations teams manage these services efficiently and derive peak performance from their cloud investments.

Cloud Discovery enables IT departments of companies to collect detailed information about their cloud-based infrastructure. Cloud Discovery finds resources in major cloud service providers.

Cloud Discovery finds resources in the following cloud providers: Amazon AWS CloudMicrosoft Azure CloudGoogle Cloud Platform (GCP)IBM Cloud PlatformCloud Discovery collects the logical datacenters associated with the account, as well as any subaccounts. Collecting information about resources on the cloud is relevant for companies, organizations, and cloud companies providing Platform-as-a-Service solutions.

IP Address Discovery:Discovery identifies and classifies information about IP addresses.

IP discovery is the process of scanning your network for IP devices through one or several methods like SNMP, ICMP, or neighborhood scanning.

Is- IP Based Discovery also known as 'Deep Discovery' , Can you also specify what is the type of access required at Machine level in that case, is there any documentation which I can find anywhere.
