Serverless Image resizing (AWS Lambda and AWS S3)<\/strong><\/p>\n

\"\"<\/p>\n

Here, we have expertise in Lambda where create different image sizes after you uploaded the origin image to the AWS s3 storage.<\/p>\n

S3 storage<\/strong><\/p>\n

\"\"<\/p>\n

Amazon S3 stores data as objects within resources called “buckets”. You can store as many objects as you want within a bucket, and write, read, and delete objects in your bucket. Amazon S3 Storage Management features allow customers to take a data-driven approach to storage optimization, compliance, and management efficiency.<\/p>\n

Lambda\u00a0<\/strong><\/p>\n

\"\"<\/p>\n

 <\/p>\n

If you want to create a thumbnail for each image (.jpg and .png objects) that is uploaded to a bucket. You can create a Lambda function (CreateThumbnail<\/code>) that Amazon S3 can invoke when objects are created.<\/p>\n

Lambda function can read the image object from the source<\/code><\/em> bucket and create a thumbnail image target bucket (in this tutorial, it’s called the source<\/code><\/em>resized<\/code> bucket).<\/p>\n

Let\u2019s setting up the AWS Lambda function\u00a0<\/span><\/h2>\n

Now that we have everything we need setup, let\u2019s start implementing our lambda function. Since it will be a python code, we will the Amazon linux machine (EC2 instance) where the function will be implemented and packaged and then uploaded to AWS Lambda.<\/p>\n

Now , please follow below steps to create new Lambda function.<\/p>\n

1.Create Lambda function.<\/strong><\/p>\n

\"\"<\/p>\n

2. Select blue print. [Here we are creating function with Node.js]. Click on Blank Function<\/strong><\/p>\n

\"\"<\/p>\n

3. Now Configure trigger.<\/strong><\/p>\n

A .Select your integration services [like S3, SNS etc..]<\/p>\n

Here, we are go with S3 service<\/strong>.\"\"<\/p>\n

4.Now we select our source bucket where original files are created.<\/strong><\/p>\n
