Learn how trading systems as a service helps you reimagine your business

by Anthony Hammond, Global Offering Lead, Trading Systems as-a-service Solutions, DXC Technology



Trading systems as-a-service solutions help organizations control operational expenditure.

And that’s vital because mounting compliance directives, ballooning product ranges and features, escalating transactions, briefer payment deadlines, steepling data speed, smarter villains and keeping people/applications connected all cost a fortune to manage.

Adopting trading systems as a service (TSaaS) and migrating platforms to the cloud offer firms the perfect opportunity to reimagine their businesses.

Critically, gaining substantial operational efficiency, including critical system transition, business transformation, application servicing, optimized support and enhanced security operations, increases market differentiation. TSaaS sharpens an organization’s competitive edge, positioning it to lead the capital markets field for CLM, treasury and trading.


Five viable trading systems as-a-service benefits

  1. More working capital: Subscribing to trading systems as a service or paying as you go avoids investing heavily in advance, and releases cash for other activities. Reduced maintenance expenditure and economic scaling enable decision-makers to forecast issues and allocate budgets more effectively.
  2. Less downtime: Firms operating trading systems as a service can look forward to greater operational resilience and significantly less downtime by adopting strong, reliable cybersecurity tactics and techniques. This is especially valuable for securities trading groups. It also helps organizations avoid hefty fines and possible reputational erosion due to breaks in business continuity.
  3. Smoother compliance: Global regulations prioritize data, privacy and resilience, increasing the complexity of compliance technology. Trade reporting, risk management and market transparency also call for meticulous real-time reporting and documentation.
  4. Tighter security: To a greater or lesser extent, aaS providers have teams of security experts to constantly monitor, signal and analyze emerging threats and critical vulnerabilities, minimizing response times and maximizing stability. Disaster recovery plans, backup systems and redundant infrastructure are all built-in features of the trading systems as-a-service model.
  5. Better time-to-value: AI, GenAI, ML, automation, easier scaling and greater flexibility improve data management, operational efficiency and time-to-value. Trading systems as a service and managed services providers control the infrastructure, updates, patches and performance issues, leaving internal business teams to do what they do best. 

Partners can make a real difference

However, to reap the true benefits of aaS adoption, firms need the kind of customization, fluid integration, risk/change management, specialist knowledge, deep technical expertise and continuing support that only an experienced systems integrator can provide.

Systems integrators bring industry-standard cost estimation, resource planning and vendor negotiation skills that are often lacking in internal teams. They also have the crucial ability to share ecosystem understanding via bespoke stakeholder training.

Also, having a trusted partner manage the transition allows firms to focus on improving their businesses rather than getting bogged down in the day-to-day running of a technology platform.

It pays to collaborate

Collaboration boosts agility, freeing resources to respond to business opportunities and regulatory requirements. Partnerships with talented external specialists can also go a long way toward increasing retention by ensuring that key internal team members work on interesting and strategic projects, expanding their skill sets while absorbing valuable cross-industry insights.

Realigning systems and processes as part of TSaaS deployment can sometimes be considered “just about the tech”. It’s not.

Meaningful and free-flowing dialogue, shared responsibilities and robust project management help avoid confusion and the inevitable consequences.
