The Evolution of Financial Services Cloud Ecosystems: From Disruption to Transformation

"Nothing is permanent except change." - Heraclitus

Introduction: The Great Unbundling

There was a time when some of the largest technology companies believed that they had unique ability to tackle the major regulated industry challenges. The industry demanded greater efficiency, risk management and global availability, among the core requirements. Many of those legacy providers built moats that were deep and well fortified. Slowly, change began to take place.

The financial crisis of 2008-2009 and the subsequent regulatory frameworks forced the financial services industry to undergo major design changes. The demand for increased transparency, measuring liquidity and the regulatory requirement to move from proprietary trading for the largest sell side banks would reshape the industry for the next 15-20 years. We take for granted the complex cloud native and model environment we swim in today.

The Pioneer Phase: Early Adopters Break the Mold (2015-2016)

There were some early adopters and use cases that drove the industry adoption and a better understanding of what the public cloud can provide to the industry. In 2015 and 2016, Capital One and Goldman Sachs launched early workloads in the public cloud. Capital One leveraged the cloud for their data and analytics workload to better profile their customer base and understand buying habits as well as risks and KYC. Goldman created use cases for risk and trading applications in the cloud.

The Pandemic Catalyst (2020-2021)

During the pandemic, cloud computing took on a different focus with most offices closing and a need to work both virtually and asynchronously. Some of the early big deals were NASDAQ's partnership with AWS and Google Cloud's partnership with the CME Group in 2021. This period marked a fundamental shift from experimental workloads to mission-critical infrastructure migration.

The Ecosystem Imperative: Beyond Simple Migration

When I started at Google Cloud, our partnership team was in its infancy in building out ecosystems of ISVs that served our customers. What does that mean to you and me? The hyperscalers use their cloud marketplaces for customers to purchase Google services to run their workloads. In its infancy, these services were Google applications and those that stood up cloud instances.

As the customers became more sophisticated in their buying decisions and the cloud commits got larger, there was a need to provide business aligned applications on the marketplace. Those applications were in most cases built on other cloud platforms or remained in on prem applications. This presented a challenge for both the need to expand Google Clouds' customers cloud adoption and to ensure that their customers were seeing the innovation necessary to continue to build and grow new applications with Google Cloud.

The Specialization Challenge

To get the customer adoption and growth needed, a whole new set of applications needed to be sourced and offered to the expanding customer base. Banking, payments, capital markets and digital assets all have unique services and architectures that require tailored solutions to enable them to serve their customers.

There are certainly core applications that run across the financial services vertical and many of the applications that run data environments, security frameworks and SRE share similarities. However; building end to end cloud native environments need an interconnected set of ISVs that collaborate, share data and deliver everything from pricing to payment reconciliation to run effectively.

The Network Effect: Creating Force Multipliers

These ecosystems of tech ISVs can become force multipliers for one another and the end user. Innovation becomes accelerated and this type of collaboration drives time to value and gives the ISVs the ability to create an offering that is more robust than they could have on their own. These shared resources also provide increased efficiency through shared resources, expertise and enhanced operational efficiencies.

Building Trust: The Foundation of Ecosystem Success

What are the shared goals of the ISV ecosystem? It is important to define the solution and the problem set you are looking to tackle. When we began building the ecosystem at Google Cloud, our focus was around cloud native trading applications and the ability to migrate on prem applications.

We evaluated many ISV applications and worked closely to build both trust and strong shared understanding of goals. Each ISV and many were on prem applications or ran on another cloud provider, needed to invest in innovation and technical collaboration to build our shared solution. Trust is often an overlooked but an essential value that ISVs share to create "better together" outcomes.

When an ISV relationship is nurtured and shaped through shared efforts of building solutions, speaking on panels, engaging in customer demos and driving growth as a team, the positive outcome is more likely. Our approach centered around our customers' strategy and our ability to create solutions that became the rails for the next generation of trading in the cloud.

Ecosystem Architecture: The Technical Foundation

Data Interconnectivity

Modern financial services ecosystems require seamless data flow between applications. This includes:

• Real-time market data feeds shared across pricing, risk, and execution systems

• Client data synchronization between CRM, compliance, and trading platforms

• Regulatory reporting data flowing from transaction systems to compliance tools

API-First Design

The most successful ecosystem partnerships are built on robust API architectures that enable:

• Standardized integration protocols reducing implementation time

• Event-driven architectures supporting real-time decision making

• Microservices approaches allowing selective component adoption

Cloud-Native Optimization

Ecosystem partners must leverage cloud-native capabilities including:

• Auto-scaling for market volatility and trading volumes

• Multi-region deployment for global markets and disaster recovery

• Container orchestration for consistent deployment across environments

The Customer-Obsessed Approach

Being customer obsessed, understanding the in-depth technical requirements and designing innovative solutions among ISVs is a suggested approach for impactful ISV ecosystems.
