Regular cloud service typically provides the infrastructure and resources for businesses to build and manage their own cloud-based applications or services. The responsibility for managing and maintaining the infrastructure, security, and other aspects lies with the client. On the other hand, a managed cloud service takes over the management and maintenance tasks, allowing businesses to focus on their core activities while relying on the expertise of the managed service provider. The provider handles tasks such as server management, security updates, backups, and monitoring, providing a more hands-off experience for the client.
