The financial world is entering 2025 with a completely different approach to technology than a year ago. After years of experimenting with isolated pilot projects, the time for large-scale implementation has arrived. Exchanges, investment banks, asset managers — they all face one challenge: how to ensure almost 24/7 trading speed, process an avalanche of data, and simultaneously reduce operational costs. The answer the industry has arrived at lies in cloud technologies.
Why cloud technologies became a key trend
Capital markets cloud is becoming not just a trendy topic, but a real necessity. Research shows that today only 5-10% of the industry’s technology solutions run on public clouds, but this number is growing rapidly. The transition to new T+1 settlement cycles on a global scale, growing trading volumes, the implementation of artificial intelligence — all this is impossible to implement on outdated infrastructure. Geopolitical instability, inflationary pressures, and regulatory requirements only intensify the pressure on financial companies.
The problem is that most firms have spent decades building complex infrastructure on top of legacy systems. The result is a fragmented environment where banks, brokerage firms, and asset managers lack data transparency, automation capabilities, and standardization. Manual processing, high maintenance costs, inability to scale quickly — all of this hinders growth. In this article, we’ll examine how cloud computing in capital markets is changing the rules of the game and helping financial institutions gain a competitive advantage.
Speed as the main currency: Why latency matters
In the world of high-frequency trading, a few microseconds determine the difference between profit and loss. Traditional data centers are physically limited — servers are located far from major exchanges, and data travels a long way. Cloud technology in capital markets solves this issue through colocation — placing trading platforms near major trading venues.
But it’s not just about physical proximity. Cloud providers optimize network architecture, use advanced data transmission protocols, and ensure minimal latency. One of the leading investment banks, after migrating its trading platform to the cloud, managed to cut trade execution time almost in half. Traders gained access to real-time information, which allowed them to make more informed decisions faster than competitors.
Additionally, cloud solutions ensure reliable data transmission even during peak loads. When markets are volatile and transaction volumes multiply, the cloud automatically scales without losing speed. This is critically important for firms operating in global markets that cannot afford system failures.
Elasticity and scalability: Pay for what you use
One of the biggest advantages of cloud technologies is their ability to scale instantly. Imagine: markets suddenly become extremely active due to a geopolitical event or the release of economic data. Transaction volumes increase tenfold. In traditional systems, this means either infrastructure overload or the need to always keep capacity “in reserve” that sits idle 90% of the time.
Capital markets cloud changes this logic. Firms pay only for the resources they use at a specific moment. During calm trading, the system consumes minimal capacity. When active market movement begins — computing resources automatically increase. This fundamentally changes the economics of IT spending: capital investments in purchasing servers transform into operational expenses that can be accurately forecasted.
For brokerage firms and hedge funds, this means the ability to quickly launch new trading strategies without waiting months for equipment procurement. Want to test a new algorithmic trading model? In a few hours, you can deploy the necessary environment, conduct tests, and make a decision. This is the flexibility that old systems simply couldn’t provide. Capital that was previously frozen in hardware can now be directed toward developing new products or improving customer service.
Analytics and artificial intelligence: From data to insights
Financial markets produce a torrent of information every second — price swings, order-book shifts, news spikes, sentiment floods from social media, satellite data, even weather patterns. The challenge isn’t collecting it. The challenge is making sense of it fast enough to matter.
One global investment firm learned this the hard way. Their data lived in different systems, and risk teams were stuck stitching it together manually. When volatility hit, they often had the numbers after decisions needed to be made. Moving their capital-markets operations to the cloud changed the game: all market, portfolio, and risk data landed in one place, updated in real time. Suddenly, intraday stress tests, scenario simulations, and exposure monitoring became instant instead of overnight — and the firm cut potential losses simply by reacting on time.
Cloud-based AI does more than accelerate analysis. It opens the door to capabilities that used to require huge internal engineering teams:
- Fraud and anomaly detection engines that monitor thousands of trades per second and flag patterns no human could spot.
- Predictive models that track market micro-signals and adjust strategies before major moves occur.
- Automated compliance workflows that reduce operational risk and keep up with tightening regulations without adding headcount.
And perhaps the most transformative shift: analysts don’t need to build massive ML infrastructure anymore. Cloud providers offer ready-to-use models, scalable compute, and experiment environments where quants can test ideas in minutes, not weeks. For smaller asset managers and emerging funds, this is a genuine level-setter — access to tools that once belonged only to top-tier institutions.
Security and compliance: Trust as the foundation
Security has always been the most sensitive issue for the financial industry. When cloud technologies first appeared, many companies doubted: can you trust storing critical data with third-party providers? Today the situation has changed dramatically. Leading cloud providers invest billions of dollars in security systems that exceed the capabilities of most corporate IT departments.
Cloud platforms offer multi-level encryption, constant threat monitoring, and automatic anomaly detection. Given the growing number of cyberattacks, this is critically important. Especially now, when financial companies increasingly rely on third-party technology providers. Regulators worldwide are tightening requirements for cybersecurity and third-party risk management, and cloud providers help firms meet these requirements.
Additionally, cloud systems facilitate regulatory compliance. New directives, such as DORA in Europe or updated Basel III rules, require financial institutions to have increased operational resilience. Capital markets cloud provides automated reporting, user action auditing, and data storage in accordance with specific jurisdiction requirements. This saves compliance teams time and reduces the risk of fines for violations.
It’s also worth noting the importance of data backup and recovery. Cloud systems automatically create backups in different geographic locations. If a problem occurs in one region — the system instantly switches to a backup center. For trading platforms, where downtime means millions in losses, such reliability is priceless.
From experiments to scaling: Practical cases
Nasdaq is one of the first major exchanges to begin mass cloud migration over ten years ago. Initially it was data storage, then T+1 reports, billing. Gradually, the exchange approached the most critical systems — the trading engine. Today Nasdaq uses cloud infrastructure for trading with extremely low latency and for market surveillance systems based on generative artificial intelligence.
The results? Nasdaq clients gained greater flexibility, faster time-to-market with new products, and reduced costs. The exchange created CapCloud — a fully managed service for its Calypso platform based on AWS. This allows clients to enjoy the benefits of the cloud without the need to build their own expertise in cloud technologies. Nasdaq takes care of support, updates, and security, while clients focus on their business goals.
Another example is leading market makers and hedge funds that use the enormous computing power of the cloud to search for alpha. Buy-side companies are moving data-intensive processes to the cloud: portfolio analysis, strategy backtesting, alternative data processing. At the same time, they’re transitioning to SaaS solutions for non-differentiating operations — accounting, reporting, customer relationship management.

Challenges and barriers: What holds back full migration
Despite all the advantages, cloud migration remains a complex process.
- The first problem is integration with legacy systems. Many firms have multi-layered infrastructure built over decades. It works, but is difficult to modernize. A hybrid approach — where part of the systems remains on-premise and part is moved to the cloud — often becomes a compromise solution. But this requires complex orchestration and can create new points of failure.
- The second problem is talent shortage. Implementing cloud technologies requires not only technical expertise, but also organizational changes and investments in staff training. Companies need specialists in data science, cloud solution architecture, and cybersecurity. In conditions of fierce competition for talent, this becomes a serious challenge. Moreover, corporate culture needs to change — from traditional IT thinking to agile approaches.
- The third point is regulatory uncertainty. Although regulators generally support innovation, different jurisdictions have different requirements regarding data storage, placement, and cloud provider auditing. For global firms, this means the need to balance between unified cloud solutions and local requirements. The issue of data sovereignty — where data is physically stored — remains sensitive, especially in sectors with high confidentiality requirements.
- Finally, cloud network architecture was not originally designed for capital markets. Latency issues, bandwidth between different cloud regions, competition for resources — all this requires specialized bridging technologies. Solutions exist, but their implementation requires additional effort.
Conclusions: Cloud technology in capital markets as a driver of the future
The transformation of capital markets through cloud technologies is not a temporary trend, but a fundamental change in the industry’s operating model. Cloud technology in capital markets allows firms to obtain what they have always strived for: speed, flexibility, innovation capability, and cost control. At the same time, it opens access to advanced technologies of artificial intelligence, machine learning, blockchain, and tokenization, which are impossible without powerful cloud infrastructure.
The next 18-24 months will be pivotal for the industry. Companies that have already begun their journey to the cloud will gain first-mover advantages: lower costs, better customer experience, ability to respond quickly to market changes. Those who wait risk losing relevance in a world where speed and data decide everything.
Now we see how exchanges, investment banks, and asset managers are rethinking their IT strategies. They understand: capital markets cloud is not about replacing some servers with others. It’s about building a digital ecosystem that allows competing in a world where technology and finance merge into one. Artificial intelligence for risk forecasting, real-time analytics for traders, automated compliance systems — all this is reality, accessible thanks to the cloud.
The industry stands on the threshold of a new era. Cloud computing in capital markets doesn’t just make processes more efficient — it creates new business models, changes market structure, and gives even small players the opportunity to compete with giants. The question is no longer whether to go to the cloud, but how to do it as quickly and intelligently as possible, so as not to be left behind in the race for the future of financial markets.
