I had created the SFTP host in my Amazon EC2 Linux instance. To connect to an SFTP host, you would require a private key. We shall see in detail about getting this key in coming sections. sftpkeybucket вЂ“ this is where we keep the private key in OpenSSH format.sftpbucketbk вЂ“ this is where the copy of the file will be stored.sftpbucket1 вЂ“ Source bucket, where external application will drop files.Make sure, you have all the ports opened as mentioned hereДЇor SFTP, I have setup three buckets, with relevant permissions. Follow this link,to create the SFTP host in an EC2 instance.

The differences are in Python Code, packaging the code and the way we will have to setup the Lambda function.ДЄgain, I used Amazon EC2 Linux instance as my SFTP host. Steps for creating S3 buckets is all same at that of the procedure described in FTP section. Delete the file dropped in the source S3 bucket.Take a backup of the data in the destination S3 bucket.

Transmit the file dropped in the source S3 bucket to the FTP host.

The code, which you had seen, does the following ThatвЂ™s it for FTP! вЂ“ These are all the steps you require to do the FTP, through Lambda function. No need to worry on advance settings, unless, you will have to work within a custom VPC. Make sure, the role has relevant permission to add and remove files from S3 bucket. Leave the Handler as the default value вЂ“ вЂњlambda_function.lambda_handlerвЂќ.В For Role вЂ“ get input from your AWS administrator, and assign/create a role. вЂњremoteDirectoryвЂќ вЂ“ if the lambda function has to perform a вЂњchange directoryвЂќ command (вЂњCDвЂќ), to a particular remote directory, user could input that directory path against this variable. In this example, I have set the following variables. Lambda enables developers to have certain configurations, in the environment variables, to give flexibility in changing those configurations, instead of changing the code. We shall discuss that approach in detail in the SFTP section.Д¬opy and paste the code from here вЂ“ FTP through Lambda Environment Variables So, we need to have a different approach for packaging our Python code. Note вЂ“ In case of SFTP, we would require external package. Select Code Entry type as вЂњEdit Code inlineвЂќ.В For FTP, we would just require the вЂњftplibвЂќ package, which comes as default with python 2.7, we donвЂ™t need any extra package. Under вЂњConfigure FunctionsвЂќ, give the relevant name and description.

In this example, I have selected it as вЂњObject Created (All)вЂќ, which would trigger the Lambda function, for any file, which is dropped into that bucket, in anyway. While configuring the trigger, select the Source Bucket, which we created in the first step.В Set the event type as required. Click on highlighted area and then choose, вЂњS3 BucketвЂќ To create a Lambda function, click on вЂњCreate Lambda FunctionвЂќ in the below screen. The AWS management console is very user friendly and all the help required are given in their own documentation. Just create an account in AWS and search for S3/Lambda/EC2. If you are new to AWS, donвЂ™t get concerned with all these new terminologies. Now, let us proceed to create a Lambda function. I setup two buckets, one for source (where a file will be dropped), another for destination (where the file will be moved to вЂ“ after performingВ FTP) Steps to setup an FTP host in Amazon EC2 Linux instance is given here I will explain the reason, in the further sections. That turned out to be a good choice, for testing. So, I setup my FTP host in the EC2 instance, for testing purpose. I regularly use Amazon EC2 Linux instance for my Machine Learning exercises. To understand how lambda works, it is better to start with FTP, rather than to start directly with SFTP. FTPДЇor doing simple FTP, all we need is IP, Username and Password. I tried to consolidate all my learning in this blog, so that you donвЂ™t need to redo the research, I had done. Being new to Lambda, I had to explore information from various links, to get the work done. Recently, I had to work on a Lambda function, to do an FTP/SFTP, as and when a file is dropped in an S3 bucket.
