Cloud Computing in Financial Services: Liberating Banks from Non-Core Businesses

 

Cloud technology is revolutionizing the financial services industry by liberating banks from non-core businesses, reducing costs, increasing efficiency, and improving security. With cloud-based services, financial institutions can access flexible storage and computing services at a lower cost, allowing them to onboard more agile capabilities and launch new businesses that require high responsiveness to market and customers. Additionally, cloud technology is enabling the at-scale application of big data analytics, which boosts demand for cloud-based elastic computing and spurs a microservice-driven architectural transformation in banking.

Major Forms of Cloud Services for Financial Institutions

There are three major forms of cloud services that financial institutions should be aware of: public cloud, hybrid cloud, and private cloud.

Public cloud infrastructure is owned by cloud computing service providers who sell cloud services to a wide range of organizations or the public. This option provides cost-effective and scalable computing resources, but it may raise concerns around data security and compliance with regulations.

Hybrid cloud infrastructure is composed of two or more types of cloud (private, public) that are maintained independently but connected by proprietary technology. This option provides greater flexibility and customization than public cloud, as organizations can choose which workloads to place on public or private cloud.

Private cloud infrastructure is built for an individual customer's exclusive use and is deployable in the company's data centers or via other hosting facilities. This option provides greater control and security over data and infrastructure, but may require significant upfront investment in hardware and software.

Financial institutions should carefully consider the pros and cons of each form of cloud service before choosing the one that best fits their needs and goals.

Cloud Computing Trends in Financial Services

Cloud computing is a rapidly evolving field, and financial services institutions must stay informed about the latest trends to remain competitive. Here are some of the key cloud computing trends that are currently shaping the financial services industry:

1. Edge computing and edge cloud: Partitioning and developing logic based on the relationship between edge devices, data centers, and the cloud is increasingly recognized in multiple industries. Development of the edge cloud is accelerating as 5G communication drives new interactions and synergy across the internet of things (IoT), cloud computing, AI, and other technologies in areas like new retail, healthcare, industrial parks, smart cities, and industrial IoT.
2. Cloud containers: Public cloud providers are actively pushing the implementation of container technology on cloud, allowing multiple workloads to run on a single operating system instance and thus reducing overheads and improving efficiency. This is driving innovation of cloud delivery models on the platform as a service (PaaS) layer. Cloud technology providers will increasingly focus on building platforms that incorporate container as a service (CaaS).
3. AI-cloud integration: AI-cloud platform applications are proliferating in fields like image and audio search, driving advances in high-value areas such as medical image analysis. Deep learning will continue to improve services for a broader range of users via cloud platforms.
4. Open banking and banking-as-a-service: The cloud is spawning new formats such as open banking and banking-as-a-service, shaking up the age-old relationship between customers and financial service providers. Cloud computing is allowing new entrants to disrupt traditional banking models and enabling financial institutions to collaborate with third-party providers.
5. Microservice architecture: Banks will recognize the potential to adopt cloud-based microservice architecture at scale in the next few years, where application programming interfaces (APIs) unlock machine-to-machine communication and allow services to scale independently without needing to enlarge the coding base of the overall offering. The next generation of core banking applications will spur a microservice-driven architectural transformation in banking.

By staying abreast of these trends and implementing them effectively, financial institutions can take full advantage of the power of cloud computing to increase efficiency, reduce costs, and improve customer experiences.

Microservice Architecture and Banking Transformation

Microservice architecture is an approach to software development that involves breaking down a large application into smaller, independent services that can communicate with each other through APIs (application programming interfaces). Each service is designed to perform a specific function and can be developed, deployed, and scaled independently of the other services in the application.

In the context of banking transformation, microservice architecture can help financial institutions modernize their legacy systems and improve their agility and responsiveness to market demands. By breaking down monolithic banking applications into smaller, modular services, banks can more easily add or remove features, scale services up or down, and respond more quickly to changes in customer needs or market conditions.

For example, a bank may choose to develop a microservice for account management, another for loan origination, and yet another for fraud detection. Each service can be developed by a separate team, using the programming language and technology best suited to their specific function. These services can then be deployed independently, and new services can be added as needed without requiring a complete overhaul of the entire application.

Microservice architecture can also improve security and reduce risk by isolating sensitive functions within their own services, making it easier to manage access control and audit trails.

Overall, microservice architecture is a powerful tool for banking transformation, enabling financial institutions to become more agile, responsive, and innovative, while also reducing costs and improving customer satisfaction.

In conclusion, cloud computing is transforming the financial services industry by enabling institutions to become more agile, responsive, and innovative. With the ability to access flexible storage and computing services at a lower cost, financial institutions can focus on their core businesses and launch new services with high responsiveness to market and customers. Furthermore, the adoption of microservice architecture and the at-scale application of big data analytics will boost demand for cloud-based elastic computing, which allows computing resources to be dynamically adjusted to meet shifts in demand. Overall, cloud computing is a powerful tool that is enabling financial institutions to stay competitive and meet the needs of their customers in a rapidly changing digital landscape.
