Identifying & Relieving the Pain Points of Storage vMotion (As Well as How to Solve Those VMware Monitoring Woes) Storage vMotion allows you to migrate a virtual machine’s entire datastore off of one storage system and into another one. It involves physically moving the entire home directory (including log, swap, config, and snapshots) to another …

vMotion or Live Migration? The two seem extremely similar. Each migrates running VMs among hosts, with unnoticeable downtime to the end users. Like a fine wine or high-performance sports car, you have to spend time with each to begin noticing the subtle, yet distinct, differences between these two.  But most people don’t have the time …

7-important-things-know-vcsa-including-vmware-monitoring

While many VMware products can share the sandbox and some toys with Windows, overall VMware has no interest in developing applications to run on the Windows OS. Hence, VMware has gradually made marked improvements to their vCenter server appliance, or vCSA, which is an Linux appliance, and includes its own built-in database, server, and security …

VMotion and Storage VMotion: What These Are and How They Work VMware VMotion and Storage VMotion are products that allow the live migration of virtual machines among various physical servers, while the VMs are running, with no downtime, no interruption in service, and total transaction integrity. VMotion improves the availability of VMs by enabling maintenance without incurring disruption …

VMware Tools is a suite of tools that installs into the guest OS. The suite is offered for Windows, Linux, FreeBSD, and Netware OSs, and the tools are created to provide an additional level of functionality within the virtual machine (VM) environment.  VMware Tools also enhance the interactions between the host and the guest machines, …

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.
