What commenters say

  • Some commenters view Fly.io as a viable alternative to traditional cloud providers like AWS and Azure, offering better performance and ease of use.
  • Others express concern about the long-term viability of Fly.io, citing the risk of acquisition or shutdown and the potential for lock-in.
  • The company's profitability and ownership of physical servers are seen as positives by some, but others note that these factors also make Fly.io a more attractive acquisition target.
  • There is a debate about the importance of trust and stability in tech infrastructure, with some arguing that it is essential for long-term success and others seeing it as overly conservative.
  • Some commenters discuss the technical details of Fly.io's infrastructure, including its use of Firecracker and Anycast, and how it compares to other cloud providers.
  • The lack of datacenters in certain regions, such as India and South America, is seen as a limitation by some commenters, but the company is eager to expand into these markets.
  • The trade-offs between using a smaller, newer company like Fly.io versus a larger, more established provider like AWS are weighed by some commenters, with some preferring the stability of a larger company and others seeing the benefits of a more agile and innovative smaller company.
