**What are Cloud Functions?**\
\
Cloud Functions is a serverless execution environment offered by cloud providers, such as Google Cloud, which allows you to run code in response to events without managing servers. It automatically scales, handles infrastructure management, and charges based on the actual compute time used, making it ideal for lightweight, event-driven applications.

**Enable required APIs** wizard will open, click on the **ENABLE** button

**Cloud Functions** wizard will open, on the **Environment** dropdown select the option **1st gen**

Scroll to the **Function name** and type "**my-first-cloud-function"**

Scroll to the **Trigger type** dropdown section and select the option **HTTP**

**What is Trigger type HTTP?**\
\
The HTTP trigger type in Cloud Functions allows you to invoke a function via an HTTP(S) request. This means the function can be executed by sending an HTTP request to a specific URL, making it suitable for creating webhooks, APIs, and handling web requests.

Scroll to the **Authentication** section and select the option **Allow unauthenticated invocations**

Allow unauthenticated invocations Check this if you are creating a public API or website.

**What is the Allow unauthenticated invocations option?**\

The **Allow unauthenticated invocations** option allows anyone to invoke your Cloud Function without requiring authentication. This means that the function can be accessed publicly over the internet without any form of identity verification.

Scroll the page and untick the check box **Require HTTPS** and click on the **SAVE** button

Scroll to the **HTTP** wizard under **Trigger** section, check all the configurations and click on the **NEXT** button

Scroll the page and click on the **DEPLOY** button

On the top right corner click on the **Notifications** icon, then click on the **Deploying Cloud Function "my-first-cloud-function"**

Deploying Cloud Function "my-first-cloud-function"

Congratulations! you have successfully Deployed a Cloud Function

On the Cloud Functions wizard click on the Name **my-first-cloud-function**

**my-first-cloud-function** wizard will open, click on the **METRICS** tab to view all the Metrics details

**What are METRICS?**\
\
Metrics are quantitative measurements used to assess, monitor, and track the performance, behavior, and health of systems, applications, and processes. In IT and cloud environments, metrics can include data points like CPU usage, memory consumption, request latency, error rates, and throughput, providing valuable insights for optimization and troubleshooting.
