Orchestrates different lambda functions based on the use case

CMP

AWS S3

Contains various essential data such as the engine binary, lambda package, templates, configurations, and outputs

Netalytics-demo

SSM Parameter store

It contains some constant data, environment-wise details, and VM image information. All information can be edited by the admin here.

parameter starting with “/cmp/”

API Gateway

The entry-point to CMP. Routes the requests from the front-end to the lambda authorizer for authentication purposes.

CMP-API-gateway

AWS Windows EC2 instance(Domain joined)

Required to run the scripts inside SSM documents for Cyberark and domain disjoin.

CMP_server

AWS Systems Manager

Used to run the script on the EC2 instance

SSM Documents: CMP-cyberark, CMP-disjoin

Azure blob storage

Contains the initial scripts to be run on AZURE VMs. Located in Nextgen environment (servicenow-rg)

cmpscript

Execution role

cmp_step_function_role

Image Added

ARN of all newly created lambdas to be configured in the json definition of the state machine.

Image Added

The resources and methods should be recreated with the appropriate lambda endpoints.

A new set of keys and usage plans to be created. New keys must be updated in the SSM parameter store and also to be shared with the ServiceNow team.

VM created in any environment must have access to this storage so that the initial scripts can be run.

Payload Key Details

• provider: Azure/AWS

• environment: same environment options as available in single vm form

• hostname: hostname of the VM to be upgraded

• ip_address: private ip address of the VM to be upgraded

• resource_group: Must be sent if the VM to be upgraded is in Azure. If not in Azure, send as an empty 

string - ””.

• update_actions: This specifies the type of upgrade. Must be passed in list of string format.

Possible values: compute_size (for modifying the instance_type of a vm)

data_disk_add: to add an additional disk

upgrade_disk: To upgrade an existing disk

For Instance, if u need to update both compute size and upgrade an existing disk you 

have to pass values in the following manner:

"update_actions": ["compute_size","upgrade_disk"]

• new_instance_type: New instance type which the user has selected

• new_disk_list: must be a string with comma-separated sizes of new disks

• Propose_disk_list: must be a string with comma-separated sizes of new disks

• request_number: Ticket number

Note: 

• if no new disk to be added then new_disk_list value must be an empty string ("").

• If no upgrade is required for any of the existing disk, you can send an empty string for Propose_disk_list.

• If an upgrade is required then Propose_disk_list must have the disks in correct order with new size.        

 For Intance: existing disks of a vm: "10,20,30"

If the user wants to change disk2 size from 20 to 50 then, Propose_disk_list value will be: "10,50,30"
