Cloud-based systems make working easier. You’ve decided that using a single physical machine that runs multiple virtual machines is a way for your business to save space, energy, and money. This goal includes the use of virtual machines using different operating systems and running multiple apps run on a single physical computer by interfacing with …

Just like cloud computing and big data, the Internet of Things (or IoT) has ceased being just a cool buzzword to toss around, and has become a factor that developers have to deal with. The IoT manifested first in the industrial world with machine sensors, instruments in engines, etc. Only recently has it taken off …

Containers aren’t new. In fact, that technology has been around for years in the form of Linux containers, which Google and other big-name tech companies got on board with and pushed heartily. But containers were a quiet, in the background kind of thing until Docker hit the scene a few years ago. Now the big …

Docker has gotten a lot of attention recently. In fact, some claim that Docker containers will eventually take over hypervisor virtualization. While that remains to be seen and really isn’t the scope of this discussion, it is important to be aware of Docker containers because the technology is gaining in popularity and is a determining …

Although you´ve done as much as you can do (or afford) to avoid a virtual machine crash, it can always happen. Sometimes you´re storage system goes down, sometime your HBA breaks or the fabric in between. Many misconfigurations lead to a non-redundant situation you find out about when it goes down. Therefore you should run …

If you are in IT, chances are you’ve at least heard about the recent VMware 2015 convention which took place in San Francisco at the Moscone Center from August 30-September 3. The convention has outgrown the typical, "Let’s see what all the cloud vendors are up to this year," and has become THE place to …

Use Case - Tamper-resistant Clinical Trials


Blockchain PoCs were unsuccessful due to complexity and lack of developers.

Still the goal of data immutability as well as client verification is a crucial. Furthermore, the system needs to be easy to use and operate (allowing backup, maintenance windows aso.).


immudb is running in different datacenters across the globe. All clinical trial information is stored in immudb either as transactions or the pdf documents as a whole.

Having that single source of truth with versioned, timestamped, and cryptographically verifiable records, enables a whole new way of transparency and trust.

Use Case - Finance


Store the source data, the decision and the rule base for financial support from governments timestamped, verifiable.

A very important functionality is the ability to compare the historic decision (based on the past rulebase) with the rulebase at a different date. Fully cryptographic verifiable Time Travel queries are required to be able to achieve that comparison.


While the source data, rulebase and the documented decision are stored in verifiable Blobs in immudb, the transaction is stored using the relational layer of immudb.

That allows the use of immudb’s time travel capabilities to retrieve verified historic data and recalculate with the most recent rulebase.

Use Case - eCommerce and NFT marketplace


No matter if it’s an eCommerce platform or NFT marketplace, the goals are similar:

  • High amount of transactions (potentially millions a second)
  • Ability to read and write multiple records within one transaction
  • prevent overwrite or updates on transactions
  • comply with regulations (PCI, GDPR, …)


immudb is typically scaled out using Hyperscaler (i. e. AWS, Google Cloud, Microsoft Azure) distributed across the Globe. Auditors are also distributed to track the verification proof over time. Additionally, the shop or marketplace applications store immudb cryptographic state information. That high level of integrity and tamper-evidence while maintaining a very high transaction speed is key for companies to chose immudb.

Use Case - IoT Sensor Data


IoT sensor data received by devices collecting environment data needs to be stored locally in a cryptographically verifiable manner until the data is transferred to a central datacenter. The data integrity needs to be verifiable at any given point in time and while in transit.


immudb runs embedded on the IoT device itself and is consistently audited by external probes. The data transfer to audit is minimal and works even with minimum bandwidth and unreliable connections.

Whenever the IoT devices are connected to a high bandwidth, the data transfer happens to a data center (large immudb deployment) and the source and destination date integrity is fully verified.

Use Case - DevOps Evidence


CI/CD and application build logs need to be stored auditable and tamper-evident.
A very high Performance is required as the system should not slow down any build process.
Scalability is key as billions of artifacts are expected within the next years.
Next to a possibility of integrity validation, data needs to be retrievable by pipeline job id or digital asset checksum.


As part of the CI/CD audit functionality, data is stored within immudb using the Key/Value functionality. Key is either the CI/CD job id (i. e. Jenkins or GitLab) or the checksum of the resulting build or container image.
