11 Cloud Object Storage to Store Public & Private Data

Invicti Web Application Security Scanner – the only solution that delivers automatic verification of vulnerabilities with Proof-Based Scanning™.

Storing massive data in a traditional environment is expensive. Let’s explore the cost-effective unstructured data storage solution we have in the market.

Thanks to cloud storage, which makes it easy and lowers the cost without compromising quality & security.

Object storage can be used to store any object like photos, video, audio, pdf, documents, static files, etc. This can also be used to host a static website or for backup purposes.

A good thing about cloud storage is you can upload and download data from anywhere on the Internet and it also give you an option to restrict it. So you have both options to choose from based on your requirement. Another worth mentioning is that you pay for what you use.

If you are looking for self-hosted S3-compliant storage, then you should try MinIO.

Let’s take a look at some of the best cloud storage services.

BTW, in this article, I am going to cover object storage solutions for applications. For personal and business use, you should check out Dropbox, Google Workspace, or other cloud storage solutions.


If you are already working in the cloud, this is pretty much guessable. One of the famous and pioneer’s in providing object storage.

Don’t bother about storage limitations; you can upload any amount of data.

AWS S3 provides 99.999999999% durability and give you an option to upload/download data using a browser, API.

There are three types of storage classes offered.

Standard – a low-latency general-purpose storage type, perfect for content distribution, big data analytics, etc.

Standard IA (infrequent access) – If the content isn’t accessed frequently, you can go for IA. IA costs less than standard and is suitable for keeping long-term data, which is not accessible daily.

Glacier – lower cost than IA and suitable for data archiving.

AWS provides lifecycle management to transition objects from one storage class to another. S3 is on a region basis, meaning you can keep your data near your customer, and visitors for faster content distribution and uploads.


And if you are thinking about DR, then it’s covered. It supports cross-region replication, which can be used for backup. Don’t forget to check out security best-practices if you decide to go with AWS S3.

Google Cloud Storage

Low-latency storage by Google for small to enterprise-level of businesses. Google offers four types of storage.


Similar to S3, GCS offers a data life-cycle too for moving data from one storage type to another. or you can also configure it to delete it.

There could be a scenario when you want to keep data only for a specific period.

Ex, the below condition will delete any data older than 30 days in a bucket.


Considering Google Cloud has multiple data centers worldwide, you can keep your data in various cities in Asia, Europe, and the USA.

Recently GCS has introduced the requester pays feature where the requester bears the data requests cost. Under the GCP free tier, you get 5 GB of regional storage to play around with.


A newly introduced storage service by DigitalOcean called Spaces has an in-built CDN.

Currently, it is available in the following four locations.

  • New York
  • Singapore
  • Amsterdam
  • San Francisco

You can either use a drag-n-drop interface or programmatically through API or CLI to control the data.

Some of the common usages of spaces are:

  • Web resources like HTML, image, CSS, js or to host the static site
  • Logs storage
  • Keeping a backup, data archive

DO Spaces is S3 compliant and supports CORS. If you are looking for a fixed-rate monthly, then DigitalOcean would be one of the cheapest ones.

The best part is the presence of a free tier that grants 10 GB/month storage, 1 million Class A, and 10 million Class B operations.


Cloud storage by IBM offers server-side encryption and SSL/TLS in transit. Data can be controlled using a web interface, RESTful API, SDK.


By using SDK, it enables you to use storage not just with IBM cloud services with another platform too. There are two resiliency options.

  • Regional – store data in multiple data center but same region
  • Cross-region – store data in multiple regions, useful if you are looking for region-based HA.

IBM offers four types of storage.

  • Standard – general-purpose data, accessed frequently
  • Vault – data accessed once a month or less
  • Cold vault – Occasionally accessed data, for long-term data retention
  • Flex – Dynamic data, a mix of data accessed frequently and infrequently

Alibaba OSS

Alibaba Cloud OSS (Object storage service) offers a 99.9% availability guarantee. Costing is based on what you use, without upfront or long-term commitment.

Alibaba storage is capable of handling more than 50,000 requests per second, and it got in-built multi-level security to protect from DDoS, unauthorized login attempts.

Azure Blob Storage

Store any unstructured data with Microsoft Azure blog storage. One of the more considerable advantages of Azure is its location.

Ex: if you are looking for multiple datacenter locations in India, then at the moment, Azure got better coverage.

Azure blog storage is optimized for data lakes. They also got other types of storage, like File & Archive, to suit additional requirements.

  • Encryption – server-side encryption with 256 AES algorithm


I know there are multiple-choice to store data in the cloud. The best way to choose is by trying them. Most of the above-listed cloud storage service providers offer a FREE trial.

Alternatively, if you would like to host them on-premises, you can try self-hosted S3 compliant software.
