Important Services in GCP
What is “Core Services” in gcp ?
In Google Cloud, core services refer to the fundamental or essential cloud-based services that form the backbone of its cloud infrastructure and offerings.
These services are designed to handle the most common cloud computing tasks and cater to a wide range of use cases, from computing and storage to networking and database management.
Here’s a breakdown of the core services:
Compute – Services that provide processing power for applications.
- Examples: Compute Engine, Kubernetes Engine, App Engine, Cloud Functions.
Storage – Services designed for data storage, from object storage to databases.
- Examples: Cloud Storage, Firestore, Cloud SQL, Bigtable.
Networking – Services that handle networking between systems and data transfers.
- Examples: VPC (Virtual Private Cloud), Cloud CDN, Cloud Interconnect.
Databases – Managed services for structured and unstructured databases.
- Examples: Cloud SQL, Cloud Spanner, Firestore.
Understanding all the “Core Services”?
What does "Compute Engine" means?
In computing, "compute" refers to the process of performing calculations or running tasks using a computer. When you hear "compute" in the context of cloud services, it means the ability to use processing power from computers (virtual or physical) to run applications, process data, or execute commands.
For example:
When you open an app on your phone, your phone’s processor is computing.
When you perform a Google search, Google’s servers are computing the results for you.
In a cloud setting, you’re renting the computing power of Google’s servers instead of using your own computer.
What does "Engine" mean?
The term "engine" refers to a system or tool that powers something or makes it work. It’s like the heart or core of a machine that provides the energy or mechanics for a process to happen.
For example:
A car’s engine is what makes the car move.
In a software context, an engine refers to the system or technology that runs processes or applications.
Together: "Compute Engine"
When you put them together, Compute Engine means a tool or system that provides the computing power (virtual machines) necessary to run applications, perform calculations, or execute programs. It’s like a powerful engine in a machine, but instead of moving a car, it "moves" or runs the computations that power your software applications.
In Google Cloud, Compute Engine provides the raw computing power you need by letting you create virtual machines that can do anything a regular computer does—but with the flexibility to scale up or down based on demand.
Types of Compute Engine Services?
1. Google Compute Engine (GCE)

What does "Identity" mean?
In computing, "Identity" refers to the way we identify and authenticate users, devices, or applications in a system. It's like having a digital ID card that proves who you are and what access you should have.
For example:
When you log into your email with a username and password, that’s your identity being verified by the system.
Your work badge or fingerprint can be used to access restricted areas or resources, similar to how digital systems verify your identity to grant access.
In the context of cloud computing, Identity usually means controlling who can access what resources, ensuring security by verifying that users, services, or applications are who they claim to be.
Identity Services
Identity Services refer to cloud-based tools that help manage user identities, control access to resources, and ensure secure authentication. These services provide mechanisms for verifying who a user (or system) is and determining what they are allowed to do.
In cloud computing, Identity Services handle tasks like:

Key Features:
Unlimited Private Repositories: Host as many private Git repositories as needed without any cost.
Integrated with Cloud Build: Automatically trigger builds and deployments from code changes in the repository.
Access Control: Manage user permissions to ensure secure access to your repositories.
Pull Requests and Code Reviews: Facilitate collaboration through code reviews using pull requests.
Use Cases:
Version Control for Code: Host your application's source code in a secure environment.
Team Collaboration: Use pull requests and code reviews to enhance collaboration among team members.
Integration with CI/CD: Automatically trigger builds and deployments with Cloud Build when code is pushed.
Backup and Restore: Use Cloud Source Repositories for backups of critical source code and facilitate recovery.
How It Solves Problems:
Cloud Source Repositories provides a secure, collaborative environment for managing source code, allowing teams to focus on development without worrying about infrastructure or access control.
Cloud Functions
Description:
Cloud Functions is a serverless execution environment that allows developers to run code in response to events. It automatically manages the infrastructure, enabling you to focus on writing code without worrying about provisioning or scaling servers.
Key Features:
Event-Driven Architecture: Trigger functions in response to various events from Google Cloud services, HTTP requests, or third-party services.
Automatic Scaling: Automatically scales the execution environment based on incoming requests without manual intervention.
Pay-as-You-Go Pricing: Only pay for the time your code is running, reducing costs for infrequent workloads.
Built-in Security: Integrates with Google Cloud IAM for secure access control to your functions.
Use Cases:
Microservices: Implement microservices architectures by deploying independent functions that handle specific tasks.
Data Processing: Process data in real-time from services like Cloud Pub/Sub, Firestore, or Cloud Storage.
API Backends: Create lightweight RESTful APIs to serve frontend applications.
Automation: Automate workflows by triggering functions in response to events like file uploads or database changes.
How It Solves Problems:
Cloud Functions enables developers to focus on writing code by handling the underlying infrastructure and scaling automatically, improving development speed and reducing operational overhead.
Cloud Run
Description:
Cloud Run is a fully managed compute platform that automatically scales your stateless containers in response to incoming requests. It provides an easy way to deploy and manage containerized applications without the need for complex infrastructure management.
Key Features:
Fully Managed Service: Deploy and run containers without managing servers, clusters, or scaling.
Automatic Scaling: Automatically scale up and down based on the number of incoming requests, even down to zero.
Support for Any Language: Run any application that can be packaged in a container, regardless of programming language.
Integrated Security: Built-in security features such as HTTPS and Google Cloud IAM for access control.
Use Cases:
Web Applications: Deploy modern web applications built with frameworks like Node.js, Flask, or Spring Boot.
Microservices: Use Cloud Run to manage and deploy individual microservices within a larger architecture.
APIs: Serve RESTful APIs to clients without worrying about the underlying infrastructure.
Batch Jobs: Run batch jobs and cron jobs in a serverless environment.
How It Solves Problems:
Cloud Run simplifies the deployment of containerized applications, allowing teams to focus on development while eliminating the complexities of managing underlying infrastructure.
