JSON and XML APIs are fundamental to Google Cloud Platform cloud storage. In addition to this, Google provides the following tools for interfacing with cloud storage.

Google Cloud Platform Console- It's a collection of cloud computing services that run on the same infrastructure as Google's end-user products including Google Search, Gmail, Google Drive, and YouTube. GCP Console offers a myriad of modular cloud services, including computing, data storage, data analytics, and machine learning, in addition to a set of management tools. A credit card or bank account number is required to register for GCP Console.

Cloud Storage Client Libraries- Google Cloud Storage enables you to store data on Google's infrastructure with high reliability, performance, and availability, and it may also be used to deliver huge data items to consumers via direct download.

Gustil Command-line Tool- It's a Python program that enables you to use the command line to access Cloud Storage. gsutil can be used to do a variety of bucket and object management operations, such as creating and deleting buckets. Objects can be uploaded, downloaded, and deleted.

Google Cloud APIs are programmatic interfaces that allow users to add power to everything from storage access to machine-learning-based image analytics to Google Cloud-based applications.

Cloud APIs are simple to use with client libraries and server applications. The Google Cloud API is accessible via a number of programming languages. Firebase SDKs or third-party clients can be utilized to build mobile applications. Google SDK command-line tools or the Google Cloud Platform Console Web UI can be used to access Google Cloud APIs.

Buckets are the main containers for storing data. We may arrange the data and provide access to the control by using buckets. The bucket has a globally unique name and a geographic location where the material is kept. A default storage class is offered, which is applied to items that are added to the bucket but do not have a specified storage class. There is no limit to the number of buckets that can be added or removed.

Object versioning is used to recover objects that have been overwritten or erased. Object versioning raises storage costs, but it assures that objects are secure when replaced or removed. When the GCP bucket's object versioning is enabled, a non-common version of the object is created whenever the object is deleted or overwritten. The properties generation and meta generation are used to identify a version of an item. Meta generation acknowledges metadata generation, whereas generation recognizes content generation.

Serverless computing refers to the practice of offering backend services on a per-use basis. Although servers are still utilized, a company that uses serverless backend services is charged based on consumption rather than a fixed amount of bandwidth or number of servers.
The cloud service provider will have a server in the cloud that operates and handles resource allocation dynamically in Serverless computing. The supplier provides the infrastructure required for the user to function without worrying about the hardware. Users must pay for the resources that they utilize. It will streamline the code deployment process while removing all maintenance and scalability difficulties for users. It's a subset of utility computing.

Cloud computing as technology was designed to give functionality to all on-demand users at any time and from any location. It has achieved this goal with subsequent advancements and simplicity of application availability, such as Google Cloud.

Google Cloud Platform (GCP) recommends using Compute Engine instance metadata to handle environment-specific variables, or information about your instances that you want to keep within your project or instance. This metadata can be used for things like performing startup configurations, storing data that your instances will use, and storing SSH keys.

Here is how to add a custom metadata to your instance:

Via the command-line:

This command will add metadata with the key key and the value value to your instance.

Via the Google Cloud Console:

In the 'VM Instances' section of the console, click on the name of the instance you want to add metadata to, then select the 'Edit' button. Scroll down to 'Custom metadata' and enter your key-value pairs there.

Once set, environment variables can be accessed from within the instance using the following API:

This method prevents sensitive data from being included directly in the code and eases the deployment process as you can use the same code across multiple environments while using different configurations. It also increases the security by protecting the data in transit and at rest.

Cloud Spanner uses TrueTime API for global synchronization and provides strong consistency, including linearizability (the strongest notion of consistency) and serializability (the strongest notion of isolation). This makes it unique among distributed databases.

In GCP, metadata is data that provides information about other data or resources. It can be associated with cloud instances or projects.
