The Challenge
Balancing Cloud Ambitions with Critical on-Prem Systems
For one of the UK’s leading insurers, the race to modernize wasn’t just about technology, it was about staying competitive in a fast-changing market. Customers expect speed, reliability, and seamless experiences, and the company knew that meant embracing cloud innovation. But there was a catch: not every system could make the leap.
Behind every policy, claim, and customer interaction are systems that can’t afford to fail. For this insurer, many critical systems run on IBM Power systems. From writing and managing policies to generating customer documents and producing hundreds of legal and business reports, these workloads keep the business moving. Any disruption would have meant delays for customers and risk for the company.
The challenge was clear: how do you pursue a cloud-first strategy without jeopardizing the core processes that keep the business running?
The Journey
A Partnership Built on Trust
Managing IBM Power environments demands deep expertise in LPAR configuration, workload optimization, security, data replication, and disaster recovery. For the client’s internal teams already focused on cloud migration and digital innovation, taking on that responsibility wasn’t realistic.
That’s where Ensono came in. The insurer already knew and trusted us — we’d been managing their mainframe since 2019 with consistently high service levels. So, when it came time to move their IBM Power systems out of a third-party data center, they turned to us again. They needed a partner who could guarantee zero disruption, keep everything compliant and secure, and give them flexibility for the future.
A Seamless Migration
Working closely with IBM, we used a swing kit to make the migration seamless. No downtime. No drama.
Once the systems were safely in Ensono’s data center, we took over full management, providing:
- Management of LPARs
- Software lifecycle, patching and security updates
- Comprehensive hardware support
- Software management for data replication and business continuity
- Backup and disaster recovery services
- Scheduling, network and storage management
The Outcomes
Freedom to Focus on the Future
The insurer now has a robustly managed and highly optimized IBM Power environment. This gives them freedom: to focus on transformation, knowing their critical systems are in expert hands−and to scale down costs as more workloads move to the cloud.
Today, those systems run smoothly and securely, and the insurer is accelerating toward its hybrid-cloud future.
Frequently Asked Questions:
How can insurers migrate IBMi and AS/4000 systems without disrupting critical operations?
Insurers can achieve zero-downtime IBM Power migration by partnering with a managed services provider that uses specialized migration techniques like swing kits. This approach allows critical systems—such as policy management, claims processing, and document generation—to transfer seamlessly to a new data center without service interruption. The key is working with a provider experienced in LPAR configuration, data replication, and disaster recovery who can guarantee business continuity throughout the transition.
What managed services are included in IBM Power-as-a-Service for financial services organizations?
Managed IBM I services or for financial services typically includes comprehensive LPAR management, software lifecycle and patching, security updates, hardware support, backup and disaster recovery services, data replication for business continuity, and scheduling, network, and storage management. This full-service model allows internal IT teams to focus on cloud migration and digital innovation while ensuring critical on-premises systems remain compliant, secure, and optimized.
How do insurance companies balance cloud transformation with legacy mid-range system dependencies?
Insurance companies balance cloud ambitions with IBM Power dependencies by adopting a hybrid-cloud strategy. This involves outsourcing the management of critical on-premises Power systems to a specialized provider while internal teams focus on cloud migration. As workloads gradually move to the cloud, organizations can scale down their Power environment costs accordingly—achieving transformation without jeopardizing the core systems that support policies, claims, and regulatory compliance.
