What Is Google Cloud Platform? : Components and Deployment steps

What is GCP?

Google Cloud Platform (GCP) Cloud Based Deployment refers to the process of deploying applications and services on Google's cloud infrastructure. It involves configuring and setting up virtual machines, containers, or serverless environments to host and run software applications.

1. Services: GCP offers a wide array of cloud services, including computing, storage, databases, machine learning, analytics, networking, and more.

2. Scalability: With GCP, resources may be scaled up or down in response to demand, enabling flexible and effective resource usage.

3. Global Network: Google's extensive global network infrastructure ensures low-latency and reliable connectivity across regions.

4. Security and Compliance: GCP offers robust security features and is compliant with various industry standards and certifications.

5. Cost Management: GCP provides tools for monitoring and optimizing costs, allowing users to control expenses.

6. Integration with Other Google Services: GCP integrates seamlessly with other Google services like G Suite, YouTube, and Google Workspace.

What is Google Cloud Run?

Google Cloud Run, on the other hand, is a specific service within GCP that offers a serverless container execution platform. It allows developers to run stateless, containerized applications without the need to manage underlying infrastructure. Cloud Run abstracts away the complexities of server management, providing a fully managed environment for deploying and scaling applications.

1. Serverless Platform: A serverless platform called Cloud Run abstracts away the requirement to manage servers so that developers may concentrate only on creating and deploying code.

2. Containerized Applications: It is designed for running stateless, containerized applications, making it easy to deploy and scale applications in a consistent manner.

3. Pay-per-use Pricing: Users are billed based on the actual resources consumed by their applications, making it cost-effective.

4. Automated Scaling: Cloud Run automatically scales applications in response to incoming requests, ensuring optimal performance and cost efficiency.

5. Compatibility with Knative: Cloud Run is compatible with any container that follows the Knative Serving API, allowing for flexibility in the choice of container image.

6. Highly Available: Applications deployed on Cloud Run benefit from Google's infrastructure, ensuring high availability and reliability.

Both GCP and Google Cloud Run offer powerful tools and services for modern cloud-based application development and deployment. GCP offers a wide range of cloud services, while Google Cloud Run specifically addresses the need for serverless container execution.

Components and Description

1. Client Devices: These are end-user devices such as computers, tablets, or smartphones that interact with the application.

2. Internet: The Internet serves as the communication medium between client devices and the cloud infrastructure.

3. Load Balancer: To improve performance and availability, inbound network traffic is divided among several servers or resources.

4. Firewall and Security Groups: Ensure security by controlling access to resources, and protecting them from unauthorized access and potential cyber threats.

5. Google Cloud Run (or Compute Engine): This is where your application runs. Google Cloud Run provides a serverless platform for running containers, while Compute Engine offers virtual machines for more fine-grained control.

6. Cloud SQL (Relational Database): A managed relational database service, providing a place to store and retrieve structured data.

7. Cloud Storage: Offers scalable and highly available object storage for storing static assets like images, videos, and HTML files.

8. Content Delivery Network (CDN): Caches content closer to end-users, reducing latency and improving the performance of the application.

9. Monitoring and Logging: Tools and services for tracking the performance, health, and behavior of the application, as well as recording events and activities for analysis.

10. Identity and Access Management (IAM): Manages user identities, permissions, and access controls, ensuring that only authorized users can interact with the application.

11. Auto-scaling and Elasticity: Automatically adjusts the resources allocated to the application based on demand, ensuring optimal performance and cost efficiency.

12. Backup and Disaster Recovery: Mechanisms to create backups of data and configurations, as well as plans for recovering from unexpected failures or disasters.

13. Compliance and Governance: Ensures that the architecture complies with industry standards, regulations, and organizational policies.

14. Networking Components (VPC, Subnets, etc.): These define the virtual network infrastructure, including subnets, routes, and gateways, to manage communication between resources.

15. Application Programming Interfaces (APIs): These facilitate communication and interaction between different components within the cloud environment.

This architecture provides a high-level overview of how the different components work together to deliver a cloud-based application on Google Cloud Platform.

Deployment steps on GCP: Using Google Kubernetes Engine (GKE)

• Setting Up Your GCP Account

  Before we dive into deploying applications on GCP, you'll need to create an account. Follow these steps:

  • Go to the GCP Console.
  • Click on "Get Started for Free".
  • Comply with the instructions to create your account, including supplying the required billing data.

  Creating Project: Once you have a GCP account, you'll want to organize your resources within a project:

  • In the GCP Console, go to the project selector.
  • Click on "New Project" and follow the prompts to create a project.
  • Click "Create" after naming your project.

• Create a Kubernetes Cluster

  Open Cloud Shell and run the following command to create a GKE cluster:

  

• Prepare your application

  Prepare your application code with a Dockerfile for containerization. Here's a sample Dockerfile for a Node.js application:

  

• Build and push Docker Image

  Build the Docker image and push it to Container.

  

• Deploy Your Application:

  Create a Kubernetes Deployment configuration file (deployment.yaml)

  

  Apply the deployment to your cluster:

  

• Expose your application

  Create a Kubernetes Service to expose your application (yaml file).

  

  Apply the service configuration:

  

• Access your Application

  You can visit your application using the external IP provided by GCP once the service has been built and load balanced:

  

  That's it! Your application is now deployed on GCP using Google Kubernetes Engine. This process demonstrates key features such as containerization, Kubernetes deployment, and service creation for application access.

Google Cloud Testing

Testing is a critical phase in the development lifecycle, ensuring that applications meet performance, security, and functionality standards. Regarding Google Cloud Platform (GCP),testing strategies are tailored to harness the platform's capabilities effectively.

Types of Testing:

• Unit Testing: Validates individual units or components of the application to ensure their correctness
• Integration Testing: Verifies interactions between different components, ensuring seamless communication.
• End-to-end Testing: Evaluate the entire workflow of an application, including UI, APIs, and integrations.
