can i use lambda function without going through proxy services

@lydiahelkinz Yes, you can. Depends on what you're scraping. On some sites you will be very successful, on others it will fail. If you hit sites running on say CloudFlare or a similar CDNs with adaptive firewalls and bot protections, you will need to advance your game as the default Lambdas won't be enough. You may still use Lambdas as your compute platform, but the HTTP handling and network access will need to be more advanced.
