What Is the Cloud Digital Leader? Glossary & Key Terms

Cloud Digital Leader
A foundational Google Cloud certification validating the ability to explain how Google Cloud products and services can be used to achieve organizational goals, aimed at both technical and non-technical professionals.
Digital Transformation
The strategic adoption of cloud and digital technologies to change how a business operates, competes, and delivers value to customers.
BigQuery
Google Cloud's serverless, petabyte-scale enterprise data warehouse for running fast SQL analytics and built-in machine learning over large datasets.
Data Lake
A centralized storage repository that holds raw structured, semi-structured, and unstructured data at scale until it is needed for analysis.
Data Warehouse
A system designed to store and analyze structured, processed data, typically used to support business intelligence and reporting.
ETL / ELT
Data integration patterns for moving data into a system: ETL transforms data before loading it, while ELT loads raw data first and transforms it inside the destination system.
Vertex AI
Google Cloud's unified platform for building, training, and deploying both custom and generative machine learning models at scale.
Generative AI
AI systems that create new content—text, images, audio, or code—by learning patterns from large training datasets.
Large Language Model (LLM)
A generative AI model trained on vast text corpora to understand and produce human-like language for tasks such as summarization and conversation.
Machine Learning (ML)
A subset of artificial intelligence where systems learn patterns from data to make predictions or decisions instead of following explicitly programmed rules.
IaaS (Infrastructure as a Service)
A cloud service model providing virtualized compute, storage, and networking resources while the customer manages the OS and above; Compute Engine is an example.
PaaS (Platform as a Service)
A cloud service model that provides a managed platform for developing and deploying applications without managing the underlying infrastructure; App Engine is an example.
SaaS (Software as a Service)
A cloud service model delivering fully managed, ready-to-use applications over the internet, such as Google Workspace.
Compute Engine
Google Cloud's IaaS offering for creating and running configurable virtual machines.
Google Kubernetes Engine (GKE)
A managed Kubernetes service for deploying, scaling, and operating containerized applications on Google Cloud.
Cloud Run
A fully managed serverless compute platform for running stateless containers that scale automatically with demand, including to zero.
Serverless Computing
A cloud model in which the provider automatically manages infrastructure and scaling, allowing developers to focus purely on application code.
Application Modernization
The process of updating legacy applications—via rehosting, replatforming, or refactoring—to take better advantage of cloud-native capabilities.
Shared Responsibility Model
A security framework defining the division of security duties between the cloud provider and the customer, which varies depending on the service model in use.
Identity and Access Management (IAM)
Google Cloud's system for defining and enforcing who can access which resources and what actions they are permitted to perform.
Virtual Private Cloud (VPC)
A private, isolated virtual network within Google Cloud used to organize and secure cloud resources.
Site Reliability Engineering (SRE)
An engineering discipline that applies software engineering principles to operations, emphasizing automation, reliability metrics, and error budgets.
Service Level Agreement (SLA)
A formal, often contractual, commitment made to customers regarding a service's expected performance or availability.
Service Level Objective (SLO)
An internal target level of reliability or performance that a team aims to meet for a service.
