Rapid AWS Management Transition Delivers Immediate Stability for Global Fintech Firm

This leading fintech supports over 500 investment management firms globally and is responsible for managing more than $4 trillion in client assets— including transactions across over 10,000 funds every day. They deliver cloud-based SaaS solutions to support sophisticated investment strategies, optimizing fund movements and treasury management. For an organization of this size, even brief disruptions can significantly impact client trust, compliance obligations, and market responsiveness. Ensuring continuous availability, reliability, and optimized performance is vital for safeguarding client and market confidence as well as ensuring operational integrity in highly competitive financial markets.

At the time of engagement, the client’s senior management and C-suite were experiencing significant flux, presenting immediate internal challenges and the need to establish stability in the AWS management, quickly

The client urgently required expert support following significant internal disruption. With an extensive AWS environment, the sudden exit of the accountable leader from the business resulted in a potential loss of critical institutional knowledge. Additionally, the existing AWS environment, consisting of nearly 600 virtual machines (VMs), lacked formal support from AWS, creating significant operational risks.

Two immediate requirements emerged:

• An urgent and sensitively managed handover—Rapid transfer of AWS management responsibilities into trusted expert hands was a priority
• Operational stability—As the business-critical AWS infrastructure was not managed by a partner and had no AWS support in place, this had created substantial vulnerabilities which needed to be addressed immediately

Well-established relationships from previous successful collaborations meant that there was already a foundation of trust and confidence in Ensono’s capabilities. The Chief Technology Officer (CTO), familiar with Ensono’s expertise through prior successful engagements, urgently requested our support. Ensono immediately responded by providing essential credentials and documentation, reassuring stakeholders, and enabling swift action. Our specialists mobilized rapidly, deploying on site to the client’s office for an intense period of critical knowledge transfer. Despite limited time, Ensono were able to assume initial responsibility within one week, effectively stabilizing operations and readying a team for next steps.

Following initial takeover, the client’s legacy data center infrastructure began to fail unexpectedly. Ensono were in place and well-enough established to complete an emergency migration of an additional 300 servers to AWS within just a few weeks, expanding the total managed infrastructure to nearly 900 servers.

A flexible onboarding strategy included establishing a dedicated fund for prioritized remediation and optimization, enabling the team to provide agile responses to emerging issues as soon as possible.

Ensono deployed, carried out vital knowledge transfer, and transitioned the client’s AWS accounts into our managed environment within just one week of engagement. The entire process—from initial contact to full operational control—was concluded within just eight weeks.

• Swift initial transition—Complete operational responsibility for the AWS environment transitioned to Ensono within just one week.
• Operational stability—Achieved significant stability and optimization of the AWS estate, reducing monthly cloud expenses by approximately 15% per month within the first nine months.
• Enhanced efficiency—Improved management and oversight, significantly mitigating operational risks and enhancing cost-effectiveness.

Given the extensive AWS environment now under Ensono’s management, there is opportunity in the future to support this client with application-level services, or by enhancing operational capabilities as their needs evolve. With deep AWS expertise—including many years as an AWS Managed Service Provider—and unique capabilities for flexible, penalty-free workload migrations, Ensono is uniquely positioned for this organization, and all our clients, to support future strategic growth. Leveraging a global team of over 3,500 specialists, Ensono ais able to deliver tailored, innovative solutions that transform traditional systems into scalable hybrid and AWS-native environments, empowering clients to adapt swiftly and confidently in evolving markets.
