The short answer to our question is this: You should monitor every service you use. Organizations use different types of cloud services, which include:
Software as a service (SaaS), such as Google Workspace, Microsoft 365, or Salesforce.
Infrastructure as a service (IaaS), such as AWS, Google Cloud Platform, or Microsoft Azure.
Platform as a service (PaaS), such as managed web application firewalls, container services, API gateways, or DNS.
Functions as a service (FaaS), such as AWS Lambda or Google Cloud Functions.
Database as a service (DBaaS), such as Oracle Cloud, Azure Synapse, or Snowflake.
