Real-time computing refers to systems that must respond to environmental changes within strict time constraints, typically milliseconds, to remain effective. This concept is crucial in applications like multiplayer gaming or video chat, where any delay can render the experience non-functional. While real-time systems strive for immediacy, they can vary in their adherence to these time constraints, sometimes achieving "near real time" performance. Technologies such as WebRTC seek to facilitate real-time capabilities, but challenges like network latency require careful design and infrastructure planning. Examples of real-time computing applications include instant messaging, video conferencing, IoT monitoring, financial transactions, and healthcare monitoring, all of which demand rapid processing and data transmission to function properly.

Telemedicine is a rapidly growing field that enables real-time, remote medical services, allowing patients to receive healthcare without needing in-person visits. It has been increasingly recommended by providers for non-urgent consultations and offers applications such as remote monitoring of vital signs and initial virtual consultations. The benefits of telemedicine include improved access to quality care, cost reduction, and operational efficiency, particularly for rural and underserved populations. Telemedicine involves the handling of protected health information (PHI), which is regulated under the Health Insurance Portability and Accountability Act (HIPAA) in the United States. HIPAA compliance is crucial for any entity involved in telemedicine, including healthcare providers and business associates, to ensure the privacy and security of patient data. This compliance requires secure app development and mandates that any breaches of PHI be reported to the Department of Health and Human Services.

A firehose API is a real-time data streaming service that continuously transmits all available data from a source to multiple subscribers, allowing them to visualize, publish, or graph the data instantly as it updates. One prominent example is the Twitter firehose API, which delivers 100% of tweets in real time, showcasing the significant volume such APIs can handle, although access to it is restricted to a few companies. Besides Twitter, data firehoses can be formed from various data sources, such as weather updates, stock prices, and Internet of Things sensors. These APIs can be syndicated, enabling the distribution of the main data stream into smaller streams for specific subscribers. The process of syndicating and consuming a firehose API can be demonstrated through applications and demos, which illustrate the practical uses of real-time data streams.

Deciding whether to build a capability in-house or partner with another company is a critical decision for businesses aiming to provide enhanced services without straying from their core competencies. Partnering can be advantageous when a company lacks expertise in a specific area, cannot support customization at scale, or needs to move quickly without sacrificing quality. For instance, Shopify and Stripe successfully leveraged partnerships to focus on their core strengths while still meeting customer demands. However, if a capability is central to a company's value proposition, building it internally might offer more control. Ultimately, partnering allows companies to focus their resources effectively, ensuring they deliver value to customers without diluting their unique offerings.
