Cloud Application Modernization Services From Hitachi Vantara

Hitachi Cloud Services



Provide a cost-effective and high-value solution.



Hitachi Vantara’s cloud solution combined with Amazon Web Services (AWS) cloud-native IoT services modernized the dispensing application and its use of supporting tools quickly and efficiently.


  • Leveraged industry-standard IoT technologies, maximizing ease of deployment, reusability and data analytics.
  • Improved security through the use of TLS (Transport Layer Security).
  • Provided expert device controller development to create highly effective management of remote, customer-facing devices.

Sestra Systems’ new end-to-end solution incorporates IoT from the consumer to the production environment, providing real-time visibility and control.

The Challenge

Sestra Systems turns beverage taps into IoT-connected devices, improving service, preventing loss and ensuring compliance. Control portion size, remotely lock taps, prevent theft, increase speed of service, and more – all with the push of a button.

Sestra Systems developed a unique solution to configure, manage and operate beverage dispensing on devices located around the world.

Sestra devices are in the critical path for their customers’ food and beverage programs, and require optimal performance, so they needed to be monitored to ensure they are dispensing without interruption.

Sestra also needed to publish diagnostic logs for each device “pour” to help its engineers troubleshoot service failures. The company wanted a “lightweight” solution to minimize latency, improve customer service, and free up device resources for servicing.

Offline functionality was also required. Sestra planned to eventually deploy these dispensing devices on cruise ships, which often go without internet for weeks, with a maximum reuse of cloud artifacts.

To meet these requirements and accelerate growth, Sestra wanted a low-cost solution, engineered for scalability and without significant maintenance costs.

Why Cloud Application Modernization Service From Hitachi Vantara?

By bringing data from different sensor types in real time to its data lake, this Cloud solution allows predictive insights to enable automatic intelligent actions (see Figure 1).

This on-premises offering delivers:

  • Accelerated time to value through reusable cloud artifacts.
  • Effective control of a wide range of devices or “things.”
  • Highly secure and easy-to-manage encryption and authentication.
  • Cloud-agnostic approach based on open standards like MQTT and the serverless framework.
  • On-premises solution that reuses cloud artifacts, allowing devices to function in remote locations with minimal connectivity.
  • AI @ Scale allows machine learning on cloud.
  • Support for data collection and decisions at edge.

This solution’s services are ready to use with any cloud IoT solution, immediately turning disconnected devices into smart devices.

All Linux and UNIX systems, as well as real-time operating systems (RTOS) are supported out of the box, with custom adapters available to handle customer-specific data publishing using open standards like JSON. And you can quickly send the data to cloud data lakes and transactional databases to modernize existing or create new intelligent customer applications.

Adoption of the MQTT protocol allows communication between connected devices and cloud IoT stacks. Combining this protocol with Hitachi Vantara’s cloud-native development and proprietary device control logic, creates a unique, reusable stack for modernizing applications and creating AI @ Scale. This architecture will grow and adapt to hyperscale workloads and easily incorporate new technologies to create new solutions.

Cloud Application Modernization Service From Hitachi Vantara

The IoT solution developed for Sestra Systems (see Figure 2) encompasses the following:

  • An MQTT agent (under 1MB of space) with a local device database running on each dispensing device.
  • Serverless framework, which creates various cloud artifacts to ingest data from cloud broker to database, including real-time visibility.
  • Reuse of the existing customer database services and presentation layers to enhance existing business use cases.
  • Bulk provisioning of devices offers a complete end-to-end solution from the factory floor to the production environment.

Once the devices are provisioned, the configurable agent service captures telemetry data like CPU usage, available memory, diagnostic logs per pour. It also services all commands.

The solution sets IoT-specific rules in the cloud to move the data from any cloud service provider’s MQTT broker to various endpoints.

Top benefits and capabilities of the solution include:

  • Scalability. Add AWS Kinesis when scaling volumes from hundreds to billions of devices.
  • Low cost and high value. Use a serverless framework to develop and deploy services.
