Accenture leverages Charon-SSP on AWS Cloud to preserve mission critical legacy applications

As part of their end-to-end migration to AWS, the Universitat Oberta de Catalunya (UOC) faced numerous challenges. One of them was the fact that as per not having updated their infrastructure for a significant period of time, they were hosting some parts of their IT platform using rather ancient and legacy technologies. AWS, as other key hyper-scalers, do not often support legacy systems, and this is generally a substantial drawback for legacy-system-based enterprises trying to migrate their IT infrastructure to the cloud.

When Enimbos Part of Accenture was appointed as UOC migration partner, there was no clear direction on what to do with some Solaris servers containing critical applications and information for UOC, because both UOC and Accenture migration teams knew legacy systems not being supported in AWS would present an impediment for the whole success of the transformation program.

Thanks to Stromasys’ Charon emulator and support team, the project team was able to successfully deploy an environment to contain these Solaris servers that were critical to UOC operation.

Once migrated, connectivity from the Charon-contained instances to the rest of the environment is effective and smooth. Now, these Solaris servers run efficiently within the Charon emulator and the client is more than happy with a cloud-based solution for a critical part of their operation than before the migration they resignedly accepted to host on-premises. – Javier Tavera, Accenture – PMO UOC Transformation Program


Charon enables OpenVMS footprint reduction

The most important steel company in Europe needed a recovery plan for IT disasters. Disaster Recovery (DR) is essential to non-stop operations like the one at the ArcelorMittal plant in Sestao, Spain. The challenge was to build recovery infrastructure for an AlphaServer system. Manufacturing of such systems stopped more than a decade ago.

ArcelorMittal has run OpenVMS on an AlphaServer for more than 20 years. The company was facing a shortage of replacement servers, a problem for thriving enterprises that depend on legacy systems. Moving its DR system to an emulated platform was a way to release its hold on legacy hardware. “We scouted four different solutions and tested them extensively,” says Process Engineer Jose Luis Laso. “We finally chose Charon-AXP from Stromasys, based on advantages that we experienced during our testing.”

Emulation-based architecture succeeds when it triggers no changes to applications. An identical platform is the goal, one where more common hardware—easy to procure, maintain, and upgrade—stands in for legacy servers. With more than two decades of solid service from its Meltshop and Rolling Mill software, ArcelorMittal wants to preserve investments in mission-critical technology.

Standing at the heart of the steel company’s meltshop and mill solution is an Alphaserver DS20. The hardware continues to serve, but its future is assured because of the Stromasys Charon emulation. “We found superior stability, ease of use, and no need to change anything in our applications,” Laso says of Charon-AXP.

On the other hand, some new opportunities will enhance the ArcelorMittal operations. “Our problem was the hard drives, because the SCSI discs in the original hardware are now out of stock,” Laso says. “We could only purchase used disks.” Building its DR systems upon standard Intel-based servers, running Charon, means IT operations will use everyday, well-provisioned storage devices.

The options for standardizing components and servers are so rich that Laso believes Charon will replace the operation’s original Alphaservers. The DR system will be leading the way to establish emulation as a production-grade choice. “By using Charon-AXP, we’re able to reproduce the same level of performance of the original systems, but with modern, standard x86 servers,” Laso says.

Adding window-driven interfaces for the legacy software is now within reach, he adds. OpenVMS applications with such a long history were first introduced with legacy user interfaces. Charon delivers windows to OpenVMS apps.

The improvements in IT infrastructure will translate to more cost-efficient operations. Laso estimates that “we’ll reduce our systems’ footprint by 90 percent” using emulated Charon servers. “We’ll be hosting all of our OpenVMS environment in one rack of x86 servers.”

Migrating Solaris workloads to AWS with Charon

A global supply chain management company that helps companies in dozens of industries replace manual and complex processes with efficient, automated, and more reliable ones was faced with the challenge of modernizing their aging data center. This included databases and applications on aging SPARC/Solaris infrastructure, something no cloud provider offers. They turned to Effectual for its technical resources and expertise and to find a solution for lifting and shifting their applications, without modification, to a modern environment.

To resolve one of the primary issues preventing a rapid migration, Effectual identified the Charon solution by Stromasys as the answer to lifting and shifting Solaris workloads, without modification, to modern x86 environments.

Following an on-premises proof of concept, the Solaris workloads were assessed for performance requirements in their native legacy environment, and virtual SPARCs were sized for VMware Cloud on AWS for hosting Solaris and native applications. Workload performance in the cloud matches that of the original SPARCS and the legacy applications (without modification) now have access to elastic storage and data protection services available in AWS.

“This project shows the true strength of what companies can accomplish together,” says Tom Spalding, Effectual’s Chief Growth Officer. “Our customer’s team and partners were able to provide business value that far exceeded what a single company could have achieved on its own. This was a result of the customer’s openness, partnership, and willingness to pursue a holistic solution; Effectual’s creativity, focus on business outcomes and desire to execute on behalf of our customers; and Stromasys’s incredible technical solution.”

By using Charon to migrate Solaris workloads, Effectual was able to clear a path and guide their customer through a complete data center evacuation. As a result, the company can now accelerate its modernization strategy and pursue its larger technical goals of making the right future-proofing selections for maintaining its leadership status on the global stage.

Charon-SSP enables UNITEC to complete their data center exit to Google Cloud in 24 days

Universidad Tecnológica de México (UNITEC) is one of the post-secondary education learning institutions under the Laureate Education, Inc., umbrella of Laureate International Universities. The CIO of UNITEC decided it was time to modernize the university’s IT infrastructure and that the most efficient way to do this was a full data center exit to migrate all IT workloads to Google Cloud.

UNITEC took full advantage of Charon-SSP’s SPARC system virtualization to move the legacy applications to Google Cloud, with no change to the applications or operating systems. The project was completed in twenty-four days.

“Given the time-crunch situation we were in, the Stromasys and Google Cloud teams stepped up and migrated all the servers, applications, and data in the promised time. I couldn’t have been more proud of the team.”

—Ivan Alonso, CIO, IT Services, Laureate International Universities


Laureate was running a SPARC T5-2 server ( 512 RAM | 32 Cores) to host their application servers, whereas the database back end was in an on-premises VMware cluster. The SPARC system had eight LDOMs, each with around 3-10 zones running Solaris OS versions 8-11.
