In the function, the code that is utilized is referred to as the function name. The lambda runtime is responsible for carrying out the function. Additionally, the tags are key-value pairs that may be used to keep track of prices or metrics. The handler is the location where the name of the function is specified together with the name of the file.<\/p>\n<p>In order to initiate a process inside the S3 bucket, the lambda function that is available in AWS S3 is used. Whenever a user visits a website with the intention of uploading images, the photo that is posted is saved in the S3 bucket.<br \/>\nIn the event that an output action takes place, such as a put operation or a gate operation, the lambda function is activated.<\/p>\n<p><img decoding=\"async\" class=\"size-medium aligncenter\" src=\"https:\/\/cloudfoundation.com\/blog\/wp-content\/uploads\/2025\/04\/AWS-Lambda-S3-Integration.png\" alt=\"\" width=\"800\" height=\"2634\" \/><\/p>\n<p>Use the lambda function to either transfer the file into another S3 bucket or save the file name and location. Both of these options are available to you.<\/p>\n<p>In the event that a get function causes the lambda function to be triggered when a user downloads a picture, the photo will be downloaded from the S3 bucket, which is where it is kept. This enables the establishment of a micro-service that is derived from the Lambda function.<\/p>\n<p>When it comes to practical applications, the process of generating an S3 bucket and using a lambda function to transfer a file to multiple S3 buckets is accomplished by using two distinct file extensions. An image file, for instance, is sent to a separate bucket than a PDF file, which is also transferred to a different bucket.<\/p>\n<p>Through the use of the S3 buckets uploading trigger, which is configured to be either as or post, the lambda code will be performed. The lambda function will be activated in a short amount of time whenever an item is posted to the shared storage bucket.[\/et_pb_text][et_pb_text _builder_version=&#8221;4.9.7&#8243; text_font=&#8221;Georgia||||||||&#8221; text_text_color=&#8221;#000000&#8243; text_font_size=&#8221;22px&#8221; text_line_height=&#8221;1.9em&#8221; max_width=&#8221;800px&#8221; max_width_last_edited=&#8221;off|phone&#8221; custom_margin=&#8221;|||10%&#8221; custom_margin_last_edited=&#8221;off|desktop&#8221; text_font_size_tablet=&#8221;&#8221; text_font_size_phone=&#8221;&#8221; text_font_size_last_edited=&#8221;on|phone&#8221; text_line_height_last_edited=&#8221;off|phone&#8221;]<\/p>\n<h2><span class=\"ez-toc-section\" id=\"The_concept_of_EC2_in_Lambda\"><\/span><strong>The concept of EC2 in Lambda <\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Lambda is a cloud computing service that offers a solution to the issue of limited storage space on Amazon Web Services (AWS).
