Here are the three best practices for financial services companies considering cloud migration.

1. Craft a Well-Defined Strategy

Before you embark on your cloud migration journey, it is crucial that a well-defined strategy tailored to your institution’s unique needs is crafted. This will maximise the benefits and mitigate potential risks. This strategy should encompass several key pillars.

Alignment with Business Goals

Start with a clear understanding of how your migration aligns with your institution’s overall business objectives. Does it aim to improve operational efficiency by streamlining internal processes, enhance the customer experience by offering innovative digital solutions, or achieve both?

Studies by McKinsey & Company highlight the tangible benefits of cloud adoption, with financial institutions seeing a 20% reduction in IT costs and a 30% increase in agility. Aligning your migration strategy with these desired outcomes ensures your cloud journey directly contributes to achieving your institution’s broader vision, increases your trust with stakeholders and the likelihood of project success.

Application Assessment

Not all applications are created equal, and some are more suited for the cloud than others. A thorough analysis of your existing application portfolio is essential to determine their cloud-readiness. This assessment should consider factors such as:

• Application complexity: Complex applications interwoven with legacy systems might require modernisation before migration, while simpler applications might be readily transferable.
• Potential risks: Identify potential security risks associated with migrating specific applications and prioritise those with minimal risk first.
• Return on investment (ROI): Prioritise applications with the highest potential for cost savings, improved performance, or increased revenue generation upon migration.

Choose the Right Cloud Migration Method

There are various cloud migration methods, each with its own advantages and drawbacks. Selecting the most appropriate method hinges on your specific needs and application characteristics. Here are three  common approaches.

1. Lift-and-shift: This method involves directly transferring existing applications “as is” to the cloud environment. While it offers a quick and straightforward migration path, it’s important to be aware of its limitations. Scaling applications migrated through lift-and-shift can be challenging, potentially leading to inefficiencies and hindering cost-effectiveness in the long run. Lift-and-shift is often suitable for simpler applications where scalability is not a critical concern, but for applications requiring frequent scaling, due to high usage, other approaches like refactoring might be more suitable.
2. Refactoring: This entails re-architecting applications to leverage the cloud’s native capabilities and features. While requiring more effort and time, this method unlocks the full potential for improved scalability, performance, and cost optimisation.
3. Containerisation involves packaging the application and its dependencies into containers, providing some infrastructure abstraction and deployment consistency benefits. However, for monolithic applications not designed for horizontal scaling, containerisation alone may not fully address scalability limitations compared to refactoring into cloud-native, decoupled architectures.

Prioritise Security and Compliance

For financial institutions, security and compliance are paramount. Your cloud migration strategy must prioritise robust security measures to protect sensitive financial data and ensure unwavering adherence to relevant regulations, including:

• Data Encryption: Implementation of robust encryption at rest and in transit safeguards sensitive data throughout its lifecycle.
• Identity and Access Management (IAM): The enforcement of strict access controls and user authentication protocols minimises the risk of unauthorised access to sensitive information. Here, the principle of least privilege plays a vital role. This principle dictates that users and/or services should only be granted the minimum level of access permissions necessary to perform their specific job functions. By adhering to this principle, you can significantly reduce the potential damage caused by compromised accounts.
• Compliance Adherence: Meticulous adherence to relevant regulations, both during the migration process and ongoing cloud operations, ensures your institution remains compliant and avoids potential legal or financial repercussions. This includes, but is not limited to Meticulously adhering to relevant regulations across multiple compliance domains is crucial, both during the migration process and ongoing cloud operations. This ensures your institution remains compliant and avoids potential legal, financial, or reputational repercussions. Key areas of focus include::
  • Data Protection and Privacy: Adhering to laws governing the collection, use, storage and transfer of personal and sensitive data like GDPR in the EU, POPIA in South Africa, and analogous regulations globally.
  • Operational Resilience and Business Continuity: Meeting requirements around system uptime, disaster recovery, and service continuity, especially for critical applications and workflows migrated to the cloud.
  • Recordkeeping and Audit: Ensuring cloud adoption supports comprehensive data traceability, auditing capabilities, and adherence to record retention obligations.
  • Cybersecurity: Implementing robust security controls and aligning with standards for safeguarding systems and data in the cloud environment.
  • Third-Party/Outsourcing Risk: Adhering to standards for diligence, oversight and governance of cloud service providers acting as third-parties or outsourcers.
  • Industry-Specific Rules: Complying with cloud-related provisions under financial services regulations governing areas like credit risk, market risk, anti-money laundering and more.
  • General Data Protection Regulation (GDPR): A regulation in EU law on data protection and privacy in the European Union (EU) and the European Economic Area (EEA). 
  • Protection of Personal Information Act (POPI): A South African law that protects the privacy of individuals by regulating the collection, use, and disclosure of personal information.

• This is not an exhaustive list. The applicable compliance landscape is complex, evolving rapidly, and varies based on institution size, geographic footprint, product offerings and other factors. Robust governance and controls that provide compliance assurance are crucial throughout the cloud journey. Institutions should consult legal and compliance experts to fully understand all obligations.

• Data Localisation: In an increasingly complex regulatory landscape, data localization is emerging as a critical consideration for financial institutions. Data localisation refers to the practice of storing and processing data within specific geographic boundaries, often dictated by regulations or internal policies. For financial institutions, understanding and adhering to data localisation requirements is crucial for ensuring compliance and maintaining the trust of their customers.

Beyond data protection and privacy laws, financial institutions must also ensure their cloud migration and operations align with sector-specific regulations around areas like operational resilience, business continuity, audit obligations, outsourcing standards, prudential requirements, and more.

Robust governance and controls are crucial to demonstrate regulatory adherence throughout the cloud journey. Financial institutions should consult legal and compliance experts to fully understand their obligations.

When you carefully consider and address these key elements within your cloud migration strategy, you can pave the way for a secure, efficient, and successful journey that will maximise the cloud’s potential for your financial institution. It’s important to note that financial institutions should always consult with legal and compliance professionals for specific guidance to navigate the complex landscape of cloud regulations.
