What is Google Cloud Storage(GCS)
Google Cloud Storage is a cloud-based object storage service provided by Google as part of its Google Cloud Platform (GCP) suite of services. It allows individuals and organizations to store and retrieve large amounts of unstructured data, such as files, images, videos, backups, logs, and more, in a highly scalable and durable manner. Google Cloud Storage is designed to provide secure and cost-effective storage solutions for a wide range of use cases. Files are stored in Google Cloud in this flow eg.
