Cloud service models are categorized into three types, each offering different levels of management, flexibility, and control. 

• Software as a Service (SaaS) – In the SaaS model, banks access the applications over the internet. Since these apps are hosted on the cloud, there is no need to install or run them on personal computers. Banks can use SaaS solutions through a subscription. MS Office 365 and Google Workspace are some of the popular examples of SaaS solutions. SaaS services can range from personal finance management tools to large CRM systems. 
• Platform as a Service (PaaS) – PaaS provides a platform for customers to build and launch applications in a cloud environment. It supports the entire application lifecycle, and yet you don’t need any infrastructure for its management. If any bank wants to develop or test a new finance app or services without worrying about its overhead or underlying infrastructure, then this model is ideal for them. Google App Engine and Microsoft Azure are some prime examples of PaaS solutions. 
• Infrastructure as a Service (IaaS) – The IaaS model refers to the practice of renting computing resources on demand over the internet or virtually. It eliminates significant expenses by providing essential infrastructure components, such as data storage, computing power, networks, and virtual machines. Banks can just rent these resources directly from the cloud service provider instead of buying or handling them. IBM Cloud and AWS are popular IaaS solutions. 

3.2 Cloud Deployment Models

Now, let’s look at three types of hosting environments where you can build, run, and manage cloud applications. 

• Private Cloud – When a cloud environment is highly regulated and maintained for a specific bank, it is known as a private cloud. This environment is usually managed either by the bank itself or a third-party service provider. This model offers increased flexibility and complete control over the system, which helps minimize the security risks. 
• Public Cloud – When a cloud infrastructure is open and shared across the entire financial services industry, it is known as the public cloud. The ownership belongs to the cloud service provider. It may be a third party or a financial organization. Banks looking for cost-effective and scalable solutions often opt for the public cloud. 
• Hybrid Cloud – This model combines both private and public clouds. It allows a local cloud to integrate with a public cloud, or vice versa. These systems are normally built for independent use, and then their tools are distributed dynamically to meet specific requirements, tasks, or workloads. 

3.3 Cloud Operating Models

There are different ways to handle IT and cloud operations. Banks and financial organizations must choose an option suitable for their requirements. 

• Virtual Captive: It is an offshore unit that provides data centers and a team of experts virtually to banks. A virtual captive reduces costs due to the low labor rates in offshore countries. Moreover, this model provides access to a global talent pool while maintaining complete control over the process. 
• Staff Augmentation: This model allows you to hire professionals with the required skills from the cloud service provider. It makes it easy to scale the team without increasing cost, allowing banks to meet changing requirements.
• Outsourcing Vendors: This model allows you to outsource some of your IT services and bring in resources from third-party vendors to handle your finance operations. By focusing on your core competencies, this model helps you adapt to market changes while maintaining a balance between investments and efficient resource utilization.
