Landis+Gyr halves costs by moving Oracle workloads to Google Cloud
Operating in over 30 countries, Landis+Gyr manages millions of smart meters for utility customers, aiming to support grid performance and energy efficiency. As global energy demand and the need for real-time energy grid intelligence increase, the company identified a requirement to shift from legacy on-premises systems to a more scalable, cloud-native infrastructure.
The migration process involved moving complex Oracle workloads - most notably the Oracle Head End System (HES) and Meter Data Management (MDM) applications - previously running on a Windows platform. The legacy environment introduced high licensing expenses, performance limitations, and restricted scalability, prompting the need for change.
Tessell and GCP
Landis+Gyr collaborated with Tessell to execute a cross-platform migration from Windows to Linux in conjunction with adopting Google Cloud's infrastructure. Tessell's platform enabled a transition that the company states achieved real-time data ingestion with sub-second latency, over 99.99% application availability, a 50% reduction in infrastructure costs, and a 60% increase in labour efficiency for database administrators. Compliance with data residency requirements across global regions was also highlighted. "Tessell's ability to execute complex Oracle migrations with precision allowed us to unlock significant operational and financial value," said Martti Kontula, Head of OT & Data at Landis+Gyr. "Our smart metering applications now run with greater agility, enabling us to deliver better insights and services to our customers while setting the foundation for long-term growth."
The project included a proof-of-concept phase on Google Cloud, which demonstrated that moving to a Linux-based system met the company's performance benchmarks. This encompassed the demands of real-time smart meter data ingestion and the required levels of system uptime and throughput at scale.
Operational impact
Landis+Gyr reports several outcomes resulting from the migration. Scalability has been enhanced through Google Cloud's elastic infrastructure, allowing for the ingestion and processing of data from millions of deployed smart meters and maintaining responsiveness during peak usage.
The company has also experienced a reduction in licensing and support costs by shifting from Windows to Linux, and a decrease in maintenance overheads. Automation of essential operations such as patching, updates, and lifecycle management has enabled internal personnel to dedicate more time to innovation and analytics.
Landis+Gyr stated that it is on schedule to retire its legacy data centres, and is adopting a cloud-first approach across its operations.
Enhancing resilience
Looking ahead, Landis+Gyr plans to extend its partnership with Tessell to improve high availability and disaster recovery capabilities. This includes deploying a multi-zone, multi-region high availability architecture on Google Cloud, automating cross-region disaster recovery with minimal data loss, and engaging in business continuity planning in line with industry standards. "With Tessell's robust cloud platform and GCP's global scale, Landis+Gyr is well-positioned to meet the rising demands of the energy sector while supporting its mission of creating a more sustainable and intelligent energy future," said Bakul Banthia, Co-Founder of Tessell.
Landis+Gyr continues to focus on improving its cloud infrastructure to respond to the evolving requirements of energy utilities and the broader market.

Java Independence is now a board-level priority - Driving cost savings, cloud efficiency and strategic agility
Chances are every time you stream content, buy something online or check your bank balance, you're interacting with Java-based systems. Java powers mission-critical systems across industries. Netflix runs its entire streaming infrastructure on Java-based microservices, processing millions of concurrent viewers. Global payment networks validate credit card transactions in milliseconds across hundreds of countries using Java applications. While the Java community has expanded to over 10 million developers worldwide, enterprises face mounting cost pressures from multiple directions. For the enterprises powering these essential services, 2025 represents a critical decision point: continue paying escalating costs for Oracle Java, potentially impacting profit margins or customer pricing as well as the potential for future price hikes, or seek alternatives. Java independence gives businesses control, choice, and confidence in how they build and run Java applications. Azul's recent 2025 State of Java Survey & Report reveals an enterprise Java ecosystem in transition, driven by mounting cost concerns, market preference for open-source solutions, and ongoing uncertainty around Oracle's licensing policies. This watershed moment stems from Oracle's shift to employee-based pricing in January 2023, which fundamentally disrupted enterprise Java strategy. Oracle's licensing practices have significantly increased Java-related expenditures, with the company generating billions annually from Java licensing and support. This shift isn't just about cost savings, it's about mitigating risk and enhancing agility. Java independence has become a board-level priority in an era where digital transformation drives market leadership. The oracle Java challenge The new Oracle pricing model detaches Java costs from actual usage, creating an unsustainable scenario: a 10,000-employee company running a handful of Java applications pays the same as a similarly sized organisation running thousands of Java-based services. For global businesses, this represents both a financial challenge and a strategic imperative to maintain competitive advantage. Our research reveals that two-thirds of organisations found Oracle's licensing model more expensive than alternatives, and an overwhelming majority reported successful migrations away from Oracle Java. With 25% of companies citing audit risk as a key migration driver, the urgency to transition has become a business priority rather than just an IT concern. The OpenJDK success story The success of OpenJDK adoption has shattered Oracle Java migration concerns. The data tells a compelling story: 84% of companies found the transition easier than expected or as planned, with three-quarters completing migrations within 12 months. This rapid timeline reflects both the maturity of available solutions and the robust support ecosystem around OpenJDK migrations. OpenJDK distributions have emerged as preferred alternatives to Oracle Java. These enterprise-ready solutions match Oracle Java SE's core capabilities while offering enhanced support and performance options. Successful migration hinges on three key components: Organisational momentum - Technical expertise, discovery & inventory tools and project planning assistance from a commercial OpenJDK provider can significantly help secure and maintain executive support, ultimately impacting a successful transition. Comprehensive Java mapping - Identifying all Java deployments across an organisation is essential. With 83% of organisations requiring commercially supported Java in production, this mapping phase is critical. Governance and compliance - Maintaining independence from Oracle Java licensing requires robust governance. Success means partnering with OpenJDK providers offering comprehensive protection, from IP safeguards to indemnification. The immediate financial benefits are substantial — most organisations report a 50-70% reduction in Oracle Java-related costs. Perhaps even more compelling, additional value lies in regaining control over Java technology strategy. Cloud cost optimisation Organisations are grappling with rapidly escalating cloud infrastructure costs, as annual global cloud spending is nearing a trillion dollars and continues to grow at double-digit rates. Our research reveals that 71% of organisations overpay for cloud compute capacity, highlighting an opportunity to reduce costs while improving application performance. Companies that select non-Oracle optimised Java platforms can save 20%+ on cloud computing costs. This is because high-performance Java runtimes deliver more stable Java applications and infrastructure while consuming fewer computing resources, creating compelling advantages beyond just licensing considerations. Powering AI innovation with Java Emerging technology demands amplify the need for change, particularly in AI and cloud computing. Half of the surveyed companies from our State of Java report already build AI functionality using Java — from financial institutions developing fraud detection systems to retailers leveraging machine learning for customer personalisation and inventory management. As computational demands grow, organisations require Java platforms that can deliver both performance and efficiency. These advanced workloads highlight the need for solutions that provide more scalable and stable applications while consuming fewer computing resources, enabling AI initiatives to be deployed successfully without excessive infrastructure investments. Oracle Java independence is not just a technical evolution — it's a strategic imperative that gives organisations the freedom to innovate, control costs, and build their technology future on their own terms.
