The advent of cloud technology brought unimaginable changes to the banking industry and sent a wave of innovative solutions with tremendous opportunities. Many banks turn to cloud-based offerings mainly to supplement their current systems and services, monetize enterprise data assets as well as improve business performance and revenue.

Those who realize the importance of extensive data analysis in terms of risk identification, fraud detection, and integrated insights have already migrated their banks or company workloads to the Cloud. So, what stops you from being next? Learn how cloud banking can be a potential game-changer for your business and get a step-by-step tutorial on how to turn your cloud-adopting strategy into an actionable plan.

What Is Cloud Banking?

Cloud banking is a powerful model, in which banks and financial institutions manage their Core Banking System in Cloud. These services might include:

  • Storage
  • Databases
  • Networking
  • Software
  • Hardware

Thanks to these services, financial institutions can manage banking platforms and applications in the Cloud. It allows them to focus on refining the quality of personal banking experiences while the IT team ensures the continuous delivery of content, applications, and services with no disruption.

What is the difference between Cloud and On-premise solutions?

The main distinction for you to understand is how cloud hosting solutions differ from on-premise ones. In a nutshell, Cloud Banking is when a third-party service provider delivers and maintains the server infrastructure that supports an application or website. In other words, instead of owning and managing their own physical servers, banks, credit unions, fintechs, and other financial institutions can opt for renting computing resources from a cloud hosting provider.

In contrast, on-premise solutions expect businesses to manage their servers themselves in their own data center. In self-hosted environments, companies get complete control over their IT infrastructure, data security, and application performance. However, let’s not ignore all the burdens, such as maintenance, upgrades, and security patches to the hardware and software.

Advantages of Cloud Banking vs On-premise Banking

Infrastructure Ownership and Management:

With on-premise hosting, a company owns and manages its own physical servers, storage, and network equipment, and is responsible for maintaining and updating them. With cloud hosting, a third-party provider handles everything and makes sure all the operations run smoothly.

Scalability and Resource Allocation:

On-premise hosting is constrained by the amount of physical hardware and resources a company has, which can make it challenging to rapidly scale up or down. In contrast, cloud hosting provides the ability to easily adjust computing resources as needed, without requiring additional investment in new hardware or software. This flexibility allows companies to respond quickly to changes in demand, whether it's a temporary surge or a long-term growth trajectory.

Cost Structure:

On-premise hosting requires a significant upfront investment in hardware and infrastructure, which can be a barrier to entry for smaller businesses. On the contrary, cloud hosting, typically operates on a pay-as-you-go or subscription-based pricing model, which allows companies to pay only for the resources they use.

Types of Cloud Hosting Environments used for Cloud Core Banking Systems

Cloud Banking can be managed in two types of clouds: Private Cloud and Public Cloud. All well-known providers of cloud hosting, such as AWS, Google, Azure, and Cisco, offer both types of these services. But how do they vary from one another?

Private Cloud is a type of cloud computing environment where the infrastructure is dedicated solely to one organization, such as a bank or financial institution. However, the fact that it is completely separated from other cloud customers makes it very costly.

In a Public Cloud environment, there is no separation between customers from the cloud hosting provider's perspective. This means that the infrastructure is shared among multiple customers, and it is the responsibility of the cloud provider to ensure that each customer's data and applications are properly segregated and secured.

Migration from On-Premise to Cloud

Here are three points to consider when migrating from on-premise to the cloud:

1) Understand your business requirements

It's important to understand your business requirements before migrating to the cloud. This includes understanding your current infrastructure and applications, as well as the types of workloads and data you need to move to the cloud. Knowing your business requirements will help you select the right cloud provider and services, and ensure that your migration is successful.

2) Plan and execute the migration carefully

Migrating to the cloud requires careful planning and execution to minimize disruptions to your business operations. You should develop a detailed migration plan that includes timelines, budgets, and resource allocation. This plan should also include contingency plans in case of unexpected issues during the migration process. It's also important to test your migration plan before implementing it to identify any potential issues.

3) Ensure data security and compliance

When migrating to the cloud, it's critical to ensure that your data is secure and compliant with regulations such as GDPR or HIPAA. This includes assessing the security and compliance capabilities of your cloud provider and implementing the necessary security measures to protect your data. You should also ensure that your cloud provider has appropriate security and compliance certifications, such as SOC 2 or ISO 27001, to ensure that they meet the necessary standards for your business.

Cloud banking is the practice of using cloud computing technology with the aid of which banks and financial institutions manage their Core Banking Systems.

Yes, cloud banking is engineered with advanced security measures and features to protect your data. With the right tools, expertise, industry-standard encryption, multi-factor authentication, and regular security audits, the safety of your customers’ data is guaranteed.

Banks and financial institutions traditionally leverage on-premises infrastructure to house their Core Banking Systems. This requires considerable investments in hardware, maintenance, and skilled professionals. Therefore, Cloud-Based Core Banking Platforms attract incumbents and fintech companies more than ever before as they wake up to the urgency of getting to the market, gaining agility, and cutting costs.

Broadly speaking, modernizing and maintaining legacy core systems can be pretty expensive. The financial services institutions (FSIs) need to take a lot of costs into consideration, including hardware costs, staff training costs, high maintenance expenses, let alone licensing fees, and vendor costs.

Core banking providers, such as Crassula, offer financial institutions one cloud-based platform that allows the latter to run their core technology in the cloud and launch highly personalized banking products.

By its nature, On-premises systems use security measures physically on the premises of a business. However, firewalls, VPNs, and antivirus software are far from the level of security cloud environments can provide. Prestigious cloud providers implement more advanced encryption protocols, multi-factor authentication, regular security audits, and compliance with PCI DSS for payment card data or ISO 27001 for information security management.

Transferring large amounts of data from one system to a cloud-based platform or switching to a new CRM system is a challenging feat. So, cloud banking providers offer backup strategies, recovery plans, application-specific migration guides, and consulting services before you go live.

Cloud services are designed to be scalable. Indeed, they operate on a pay-as-you-go pricing model. It means that the fintech companies are only charged for the resources they use, making it very convenient to scale up during peak periods and scale down when demand is low.

Cloud platforms offer a high degree of flexibility. For instance, certain cloud providers have serverless computing models that allow FSIs to define custom logic using code snippets, functions, or microservices without managing the underlying infrastructure. They also provide low-code or no-code development platforms that enable FSIs to create applications and workflows using visual interfaces and pre-built components.

Cloud providers typically offer a comprehensive marketplace encompassing diverse third-party integrations and services. At Crassula, for instance, there’s an entire page devoted to the integrations and partner programs the clients can benefit from.
