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 announce and/or learn about all things cloud, and indeed, all things relating to data center infrastructure. If you’re in Europe, it’s not too late to participate in VMworld 2015. Those on the right side of the Pond can catch it in Barcelona from October 12-15 at the Fira Barcelona Gran Via.

VMworld 2015: A Recap

Gather at VMworld 2015

VMworld has become more than just a vendor’s show. It’s now the best place to meet and engage with the industry leaders in data center infrastructure.

Day one of VMworld 2015 was primarily focused on data center infrastructure. Day two focused mostly on the clients, including management issues, applications, and security issues. The traditional talk by CEO Pat Gelsinger was moved to a more prominent place in the program. Gelsinger spoke about the current motto and theme of VMware, One Cloud, Any App, Any Device." Gelsinger also illustrated the challenges put forth on today’s cloud service providers, stating that they have to figure out how to, "innovate like a startup and deliver like an enterprise."

The most prominent theme of this year’s event was the hybrid cloud. Specifically, VMware is touting the hybrid cloud that spans a number of separate public and private clouds. In this hybrid cloud, workloads shift automatically across cloud environments, depending on the demand for and availability of the resources. One industry term for this is ‘cloudbursting’. The latest version of VMotion provides this capability.

In reality, not many businesses are actually doing this. Nevertheless, VMware wants users to know it’s available, and really, really want them to start doing it even if they don’t want to.

VMworld 2015 also crowned the first ever VMworld Hackathon winner. This event drew lots of attention and media coverage. The event was geared toward developers and lasted all day.

Much of VMworld was also the typical "meet the vendors" atmosphere, though many of the industry’s movers and shakers chose to remain unregistered and spend their time meeting with colleagues, chatting it up with customers, and getting their heads together with industry analysts.

VMworld 2016: A Peek Ahead

VMworld 2016

It’s not too late to catch VMware Europe in Barcelona, Spain. Or, go ahead and register for VMware 2016 in Las Vegas.

It’s not too early to begin making your plans to visit next year’s VMworld. VMworld 2016 in the U.S. is scheduled for August 28 through September 1, and will be held at the Mandalay Bay convention center in Las Vegas. For those in Europe, VMworld 2016 will again be held at the Fira Barcelona Gran Via on October 17-20.Need a better way to keep up with all things VMware?

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.
