Let's look at a website that generates a Meme. Suppose the user wants to upload a photo and wants to convert into Meme. User uploads a photo on a website and website might store a photo in s3. As soon as it finished uploads, it triggers a Lambda function. Lambda analyzes the data about this particular image to SQS, and this data can be "what the top of the meme should say", "what the bottom of the meme should say", the location of the S3 bucket, etc. The data sits inside the SQS as a message. An EC2 instance looks at the message and performs its job. An EC2 instance creates a Meme and stores it in S3 bucket. The best thing is that if you lose your EC2 instance, then also you would not lose the job as the job sits inside the S3 bucket. Suppose the user wants to look for a package holiday and wants to look at the best possible flight. AUser types a query in a browser, it then hits the EC2 instance. An EC2 instance looks "What the user is looking for?
