SaaS is widely used and allows firms to subscribe to a service where they access software that is centrally hosted and managed, via the internet. Popular software applications include CRM solutions like Salesforce, but many niche software vendors now offer a SaaS delivery model for their compliance solutions, order and execution systems, research tools and risk management software.
PaaS can be utilized effectively by firms with in-house developers who may be looking to build or trial new software applications, without building a test environment in-house.
IaaS allows firms to completely outsource their IT environment to a data center that is owned and managed by an outsourced provider, such as RFA. In this case, clients are usually billed by the amount of resources allocated and utilized. If a completely outsourced model isn’t suitable, firms can take DaaS facilities, using desktop virtualization, which allows users to access their desktop by logging into the corporate network via a web browser. In the event of a user’s machine being lost, stolen or broken, a replacement machine can be up and running immediately with no loss of secure data.
