Cloud is the key transformation lever as capital market firms balance their IT spend across regulatory compliance, legacy modernization, and engineering of customer experience / journeys to achieve a competitive edge. It accelerates digital transformation with disruptive models to meet ever-changing regulatory requirements, enable faster economic decision making, and deliver great customer experience. Cloud provides ubiquitous availability of a large set of constantly evolving IT services, securely delivered at up to hyper-scale in consumption-based models. According to Gartner, by 2020, a corporate "no-cloud" policy will be as rare as a "no-Internet" policy is today1.
Challenges that can be addressed by cloud adoption:
Figure 1: Capital markets cloud adoption trends
Capital markets firms adopt cloud computing for the following key drivers:
Key considerations for cloud adoption
Financial services firms, specifically in capital markets are taking up “large scale movement to cloud” with a strategy of private (all core, crown jewel applications) and public cloud (all non-core) migration as the industry faces competitive pressures from early adopters. Innovation in business models accelerated through Cloud, Digital, and AI/ML drives products and experiences for trading and investments. Cloud is the new lynchpin in this transformation being driven by fin-techs and fast follower incumbents.
Considerations for cloud (Table 1) vary based on the business use-case and risk tolerance of the institutions. Capital markets firms across sell-side and buy-side are recognizing the limitations of traditional models of building trading systems in-house with legacy infrastructure and architecture.
Table 1: Considerations for cloud migration
Whatever the business use-case and drivers, there is a range of cloud deployment options available from a multitude of cloud service providers: Software as a service (SaaS), Platform as a service (PaaS), Business Process as a service (BPaaS) and Infrastructure as a service (IaaS).
The other big fork in the road is the choice regarding public or private cloud. Large firms have taken a cautious approach keeping core (trading, portfolio management) applications in private cloud leveraging IaaS. The SaaS model is attractive for HR, Finance, and CRM capabilities. PaaS is being used for modernization of legacy applications in trading, customer service and the financial advisory space. Key business processes for cloud include:
Integrated strategy for cloud migration/ transformation
Financial services cloud implementation requires an integrated cloud strategy and delivery as depicted below.
Figure 2: Integrated Cloud Strategy
Whatever your current disposition and target requirements, there is a specific journey that can be defined. Any new applications should be built using the latest application patterns and delivery best practices (DevOps, resilience, asynchronous, API enabled, containerization etc.). Others can undergo lift-and-shift into the cloud and existing data center. The key message here is about the speed of change in the cloud.
The journey to cloud still faces a few challenges and pitfalls, such as:
Cloud is not a technical project: Cloud operating model is based on a new way of working. The journey needs to be business led.
Be careful of consumption: On-demand access, almost infinite capacity even at a low unit-price can result in higher costs if not managed.
Cloud is not Hosting 2.0: This is a view that can leave value on the table. User experience and speed of doing business are key value dimensions.
Case-in-Point Examples
Typical cloud journey
Hybrid-cloud is core to today’s cloud journey with a mix of on-prem, private cloud and public cloud. The workloads on public cloud can be across platforms like AWS, Azure, IBM Cloud, Google Cloud Platform, etc. However, this needs to be a calculated decision based on concentration risk vs. management overheads. The key strategy and decision attributes for a multi-cloud strategy can be gleaned from the diagram below.
Figure 3: Cloud Strategy attributes for Multi-cloud
Integrated cloud adoption strategy and the below-mentioned solution steps will address significant cloud migration challenges:
Cloud readiness assessment
As part of cloud readiness assessment, a complete business case recommendation (Figure 4) needs to be developed. Cloud journey should focus on minimal risk and impact to current business through a well-defined approach based on business criticality, regulatory needs, business velocity and customer experience
R-Lane Migration Approach
Application rationalization is a key requirement for cloud adoption. This involves identifying the decision paths/ R-Lanes for (Re-host, Re-factor, Re-build, and Re-Architect) the migration. R-Lane methodology drives cloud migration strategy right from assessment, design, build, and migration
Cloud Deployment approach
The migration will need to be a phased approach with a clear strategy for deployment options in terms of model, CSP, and public / private decision. This will vary depending upon the business risk appetite of the firm, a mix of homegrown and COTS applications, complexity of the organization, and end-customer considerations.
The initial phase can focus on crown-jewel critical applications to be retained in a refreshed infrastructure, moving somewhat-critical applications to private cloud and moving non-critical applications into public cloud or SaaS. The subsequent phase can focus on moving somewhat-critical applications to public cloud. A detailed assessment of the landscape is required prior to this decision.
