Key Features of AWS S3 and Key Features of GCS

AWS S3 is an object level storage service by Amazon Web Services. It provides storage for unstructured data rather than file or volume data. So, AWS S3 stores its data as objects within buckets. With AWS S3, you can store any amount of data, create a data backup, or retrieve it at any time from any device.

Besides, AWS is used by companies worldwide to store and protect data for various use cases. These include mobile applications, websites, data lakes, IoT devices and big data analytics. Besides storage, AWS provides management features. These features enable users to organize, optimize, and configure data access to meet specific business needs.

Google Cloud Storage is an object level storage platform by Google Cloud Platform (GCP). Primarily, it provides storage for unstructured data sets. Also gives you a flexible way of managing your storage. Ideally, Google Cloud Storage was designed as a competitor for AWS S3. To establish a connection between AWS S3 and AWS EC2, you can interact with S3 from an EC2 instance using various methods, such as the AWS CLI, SDKs, or even via REST APIs.

How AWS S3 Works and How Google Cloud Storage Works

How S3 Works

S3 Works

Amazon S3 data is stored as objects. This approach enables highly scalable storage in the cloud. Objects can be placed on a variety of physical disk drives distributed throughout the data center. Amazon data centers use specialized hardware, software, and distributed file systems to provide true elastic scalability.

Amazon provides redundancy and version control using block storage methods. Data is automatically stored in multiple locations, distributed across multiple disks, and in some cases, multiple availability zones or regions. The Amazon S3 service periodically checks the integrity of the data by checking its control hash value. If data corruption is detected, redundant data is used to restore the object.

Buckets:

A bucket is a container for storing objects in S3. Each bucket is uniquely named and exists within a specific AWS region. Users can create, delete, and manage buckets and set permissions at the bucket level.

Objects:

Objects are the actual files or data stored in S3. Each object consists of data (file content) and metadata (information about the file, such as size, timestamp, etc.). Each object in S3 is identified by a unique key within a bucket.

Regions:

Buckets can be created in specific AWS regions. Storing data in different regions can help achieve lower latency or fulfill regulatory requirements.

Access Control:

Access to S3 resources is controlled through IAM policies, bucket policies, and Access Control Lists (ACLs). Permissions can be set to allow or deny access to individual buckets or objects.

Storage Classes:

S3 offers multiple storage classes designed for different use cases and cost structures, such as S3 Standard, S3 Intelligent-Tiering, S3 Standard-IA (Infrequent Access), S3 Glacier, and S3 Glacier Deep Archive.

Data Management:

S3 provides tools for managing data, including Versioning (to track changes to objects), Lifecycle Policies (to automate data retention and deletion), and Replication (to copy objects between different buckets or regions).

Data Integrity & Security:

S3 supports server-side encryption (SSE) and client-side encryption to protect data at rest. It also integrates with AWS Key Management Service (KMS) for key management. Object Locking and MFA (Multi-Factor Authentication) Delete offer further protection for sensitive or critical data.

S3 Operations:

PUT Operation:

Used to upload an object to an S3 bucket. When you PUT an object, you can specify the storage class and any relevant metadata (like file type or cache control).

GET Operation:

Retrieves objects from the bucket. You can either download the object directly or use a signed URL for temporary access.

DELETE Operation:

Removes an object from a bucket. You can also delete entire buckets and all associated objects.

HEAD Operation:

Retrieves metadata about an object (without downloading the file).

LIST Operation:

Lists objects in a bucket, either by default or based on certain prefixes or filters.

 

Google Cloud Storage vs AWS S3: How GCS Works?

 
Google Cloud Storage vs AWS S3


Google Cloud Storage (GCS) is a scalable and secure object storage service provided by Google Cloud. It allows users to store and manage large amounts of unstructured data, such as media files, backups, and data archives.
Buckets:
A bucket is the main container for storing objects in GCS. Each bucket is uniquely named and associated with a project.
Buckets define access controls and the geographic location where the data is stored.
Users can create, delete, and manage buckets.
Objects:
Objects are the actual data (files) stored in GCS.
Every object consists of the data itself (such as a file) and associated metadata (like content type, size, etc.).
Each object within a bucket has a unique key, which is the object’s name.
Storage Classes:
GCS provides various storage classes to optimize costs based on the frequency and speed of access. These include:
Standard: Best for data that is accessed frequently.
Nearline: Suitable for data that is accessed less than once a month.
Coldline: For data accessed less than once a year.
Archive: For long-term storage with very infrequent access.
You can change the storage class of an object without moving the data to a different bucket.
Key Features:
Data Redundancy:
GCS automatically replicates data across multiple locations to ensure durability and availability.
The data can be stored in different locations:
Regional: Data is stored in a single region for low-latency access within that region.
Multi-Regional: Data is stored across multiple regions, providing higher availability.
Dual-Regional: Data is stored in two specific regions for redundancy.
Access Control:
Access to buckets and objects is controlled through Identity and Access Management (IAM) roles, Access Control Lists (ACLs), and bucket policies.
These controls allow for fine-grained permissions for users, projects, or applications accessing the data.
Object Versioning:
GCS supports versioning, which allows you to keep multiple versions of an object in the bucket.
This helps in recovering previous versions of objects in case of accidental deletion or modification.
Lifecycle Management:
You can define lifecycle policies to automate tasks such as transitioning objects to lower-cost storage classes, archiving, or deleting them based on specific conditions.
Encryption:
GCS encrypts data by default using Google-managed keys.
It also supports customer-managed encryption keys (CMEK) via Google Cloud Key Management Service (KMS), allowing more control over encryption keys.
Data Transfer:
GCS supports uploading and downloading data via the Google Cloud Console, gsutil (command-line tool), and APIs.
It also provides Signed URLs to allow temporary access to private data without exposing credentials.
Cross-Bucket Operations:
GCS supports Object Replication, which allows objects to be automatically copied from one bucket to another in different locations, ensuring data durability and availability in multiple geographic regions.
Event Notifications:
You can set up event notifications for various operations (e.g., when an object is created or deleted) and trigger Cloud Functions or Pub/Sub for automation.
