Save energy without reducing VM performance in your VMware vSphere cluster

Over the last couple of decades energy consumption went up massively in every data center and while the costs were always high, they were manageable. For some time you can see more and more companies that started “Green Initiatives” to reduce energy waste and the sudden energy crisis accelerates the need for change, One of …

Rust-based Ransomware can hit anywhere including Windows, Linux and VMware ESXi

While it’s great for application developers to write applications in a language that runs seamlessly on many different operating systems, there is a downside to the application’s intention. Ransomware has damaged many companies, causing downtime, money, and sleepless nights. Looking into some statistics you can find damage predictions of $265 billion by 2031. Writing Ransomware …

Multi-CPU Github Actions with Go for automatic builds and tests

Bart, a core developer in our immudb team recently published a very interesting article to use GitHub Actions to automatically build and test on many different CPU architectures that are not very common and often not available. When we think about CPU architecture usually there’s one leader that comes to our mind – the famous x86-64 one. …

Metrics & Logs support for IoT – Bringing Secure Monitoring and Logging to the Edge

Simple uptime monitoring for Internet-of-Things (IoT) is well-known and requires knowing if the devices are up and running. Having additional long-term performance data, secure (tamper-proof) logging at your Edge devices is only a tiny step when using Metrics & Logs. With our support for device, infrastructure, and application metrics as well as Syslog data, you …

Serious security vulnerabilities in Atlassian Confluence affect many organizations

Last weekend was all about releasing fixes for a major (critical) Confluence server vulnerability, tracked by CVE-2022-26134, that allows an unauthenticated attacker to execute arbitrary code (remote code execution, RCE). You should be very aware of that vulnerability as Confluence servers are a very attractive target for initial access to a corporate network. Therefore, systems …

Always know about the dependency of your Pods – here comes SBOM operator for Kubernetes

Some months ago Christian Kotzbauer started a community project called SBOM operator that created SBOMs based on the container images used by the Pods and stored them in a Git repository. His main intentions were to have a Kubernetes-native way to generate and store Software Bill of Materials for all running container. Thinking about the …

Use Case - Tamper-resistant Clinical Trials

Goal:

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.).

Implementation:

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

Goal:

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.

Implementation:

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

Goal:

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, …)


Implementation:

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

Goal:

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.

Implementation:

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

Goal:

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.

Implementation:

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.
