Public Cloud

What is a Public Cloud?

Public cloud refers to computing services—including servers, storage, databases, and software applications—delivered over the internet by third-party providers and shared across multiple organisations. Public cloud infrastructure is owned and operated by cloud service providers. These providers manage the hardware, maintenance, and security of the underlying systems.

Accounting firms using public cloud software access applications through web browsers or mobile apps without installing or maintaining local infrastructure. The provider handles software updates, security patches, data backups, and system availability. Multiple clients of the provider share the same infrastructure whilst their data remains logically separated and secure.

Public cloud solutions typically operate on subscription-based pricing models, allowing firms to scale usage up or down based on requirements. Features include automatic software updates, accessibility from any location with internet connectivity, integration capabilities with other cloud services, and built-in disaster recovery. Data is stored in the provider’s data centres, often with geographic redundancy across multiple locations.

When evaluating public cloud accounting software, firms should consider data sovereignty requirements, particularly where client data must remain within UK jurisdiction. Security certifications, encryption standards, access controls, and compliance with regulations such as GDPR are essential factors. Understanding the provider’s service level agreements, data backup procedures, and business continuity arrangements helps firms assess whether the solution meets their operational and professional requirements.
