Building a personalized video platform requires careful consideration of various concerns, including application requirements, technical implementation, and scalability. Choosing the right API/SaaS provider is crucial, as it can impact deployment, security, and integration capabilities. Key questions to ask when selecting a provider include the types of video interactions supported, recording capabilities, encryption options, and integrations with additional features like whiteboards or chat. Defining video app requirements helps provide a clear structure for the application, while also considering platform targets, user registration and authentication, video use cases, add-ons, encryption requirements, customer satisfaction metrics, and long-term storage needs. Addressing day two concerns such as observability, visualization dashboards, and long-term storage is also essential to ensure a successful launch and ongoing maintenance of the application.
