8/16/2023 0 Comments Filezilla to s3![]() Uploading into S3 from the internet is free. What is it? Price Comparisonįirstly, let’s remind ourselves about S3 and EFS. At the time of writing in January 2021, AWS Transfer Family for EFS is red hot off the press as the latest endpoint available, and finally we have a way to examine and transfer files into our EFS volumes without having to mount them somewhere first!īut, as with all managed services this comes at a price. The offering is essentially a managed FTP service with S3 as the endpoint for the data. So clearly, we needed more… AWS Transfer… Orphan?ĪWS Transfer Family started out as AWS Transfer for SFTP in November 2018, and rebranded and expanded to include FTPS and plain FTP in April 2020. I’m sure it’ll be a feature that comes along eventually, but in the meantime I feel a bit blind not knowing what’s on my EFS unless I mount it somewhere to inspect it! At the time of writing EFS also doesn’t have a front-end file manager in the AWS Console. It still needs to be mounted to an EC2 instance (or latterly, an ECS container or Lambda function), but it at least is a fully POSIX-compliant file system. Still the same issue though, you can’t FTP into it directly. But where EBS charges you for storage provisioned (regardless of whether you fill it or not), EFS only charges you for what you use and could end up being far cheaper depending on how much headroom you’re putting into your EBS volumes – and of course EFS can be mounted to multiple different instances so overall you’ll get some good mileage out of it for the cost. It’s more expensive than EBS (which is $0.08 per gb/month with the new gp3 volume) at a whopping $0.30 per gb/month. Then along comes EFS in June 2016 – AWS’ version of the classic Network File System (NFS) for Linux only (look for Amazon FSx for a Windows solution). Unsecured FTP on port 21 has been a big no-no for a very long time, so really when I say FTP I mean some secured method which is one of: SFTP (FTP extension of SSH) or FTPS (FTP with SSL certificate). ![]() Now I need to point out I’m being glib with my casual use of the term ‘FTP’. Maybe not a dealbreaker, but be aware.īut with it mounted to an EC2 instance, you could install your favourite FTP server and upload ‘directly’ into S3. ![]() With s3fs, all of those requests can start to mount up. This might not sound like much, but if you inadvertently trigger or have running some background processes that are read/write intensive, you wouldn’t normally think about it. There’s also the risk of ramping up significant costs – filesystem operations translate to S3 API requests which have a cost of $0.0 PUT, POST, and LIST requests, and $0.00 GET, SELECT, and other requests. Those that are are a cunning kind of alias to S3 operations that emulate equivalent behaviour. What it can’t do however is get away from the fact that S3 is not a filesystem, and not all POSIX commands are supported. With a development history going all the way back to 2008, it’s been impressively and consistently developed, adding in new features and bug fixes. Naturally the community responded and s3fs-fuse is a utility that allows you to mount S3 as a filesystem to your EC2 instance. When I started using AWS, one of the first things I can remember searching for was “Can I FTP files to S3?”, and that’s a no. But what is it really, why does it exist, and when would you use it? A Historical GapĪWS used to have this small problem – it offered some awesome and powerful storage solutions like EBS (which needs to be mounted to an EC2 instance) and S3 (which you could only interact with via the console, SDK, or CLI). If you were curious what AWS Transfer Family is, I’ve already spoiled it in the title.
