Whether public cloud services are sufficiently secure, stable and high performing for a particular use case is really individual to the specific application, the provider and, of course, the organization using the application. Though some high-profile outages of public cloud services still occur, we are seeing some providers offer service level agreements (SLAs) that address availability for their public cloud services that are comparable to what an enterprise might expect from a dedicated service.
A public cloud service is probably perfectly adequate to support non-core applications, assuming that you have a high degree of trust in the provider and that the provider can offer additional reassurance in the form of sufficient service level guarantees around elements like service availability and response time.

Despite some high profile outages, we are seeing organizations demonstrate a strong level of comfort in public cloud services. Enterprises are using Infrastructure-as-a- Service (IaaS) for on-demand compute and storage services to support test and development, short-term marketing campaigns and storage backup for tier 2 or tier 3 data. In terms of Software as a Service (SaaS), public cloud services have proven sufficiently stable to support applications like messaging and collaboration, productivity and customer relationship management (CRM). Public cloud solutions can also be a good, low-cost option for virtual data infrastructure (VDI) solutions delivery.
