Here is a neutral and interesting summary of the provided text in one paragraph: The 2019 RapidAPI Developer Survey revealed that APIs continue to be an essential tool for software developers, with companies of all sizes and industries relying on them. Most respondents expect to use APIs more in 2020 compared to 2019, while only a few anticipate reducing their API usage. The survey found that internal API usage increases significantly with company size, and coding experience correlates with API usage. Developers primarily deploy APIs using virtual machines (VMs), with serverless platforms being a close second. Emerging technology trends, such as serverless and FaaS, were of particular interest to developers. Additionally, AWS was the most popular API gateway, while Postman was the most popular API design tool. The survey also highlighted the importance of internal APIs over external ones, with companies using more internal APIs than external ones on average.
