If you are new to AWS, or new to AWS Lambda, this book will help flatten the learning curve and make you design solutions of enterprise class. All you need is a very basic level of understanding of Python.Setting up the environment : One of the biggest hurdles in using Lambda is how to set up everything on your laptop and on your AWS account. This book explains each step in great detail, including: 1. Setting up of a VPC, NAT Gateway, IAM roles for AWS Lambda, Security Groups, Subnets (public & private), Internet Gateways, Route tables, etc. 2. Setting up of an RDS instance 3. Setting up RESTful services via the API Gateway that connect to Lambda functions 4. Setting up of a Linux code server and installing the Python virtual environment 5. Setting up of a Windows server and installing MySQL Workbench 6. Creation of automation scripts for upload of Lambda programs 7. Configuring the laptop to connect to AWS 8. Configuring Cloudwatch to trigger Lambda functions Understanding AWS Lambda : The main topic of this book, this explains how to use Lambda functions to perform multiple tasks, including: 1. Database connectivity (RDS) 2. Working with both Standard & FIFO Queues (SQS) 3. Sending notifications (SNS) 4. Performing facial recognition (Rekognition service) 5. S3 interactions & triggers 6. Working with Excel files (create and read) via S3 & Lambda functions Creating an enterprise-class solution: The true power of Lambda comes when used to solution an end-to-end business requirement, which is what was done the author at Tata Capital and presented at the AWS Mumbai Summit in 2017. This same design methodology has been explained in detail using a simple cricket team and ranking project, which also performs the task of facial recognition of team players based on JPG files. The solution also covers the automatic synchronization of data between two databases on different servers (which is a painful challenge), using queues and Lambda functions. And here is the punchline: The entire project has no dedicated server, and everything is coded using serverless Lambda functions and other services of AWS mentioned above! This is zero maintenance stuff About the Author Ajay is the Senior Vice President & Chief Technology Officer at Tata Capital Financial Services Limited, with over 27 years of experience in the Information Technology field. Passionate about technology, he was responsible for introducing Tata Motors Limited as well as Tata Capital Limited to the public cloud (AWS).

Very easy to use and clean
Size: 22'' X 22''
Saved my pad training with my puppy. It's firm and easy to clean. It holds the pads well for the most part, but sometimes my dog gets a little crazy and it comes out, but I don't think it could be better. Still give a 5-star!

Don’t buy
Size: 28'' X 34''
Mine arrived broken and scratched I think I received one that someone had returned. It also doesn’t hold pads that well my 4 lb teacup Yorkie is able to pull the pad off of the pad holder without even ripping the pad.

Excellent!
Size: 22'' X 22''
Highly recommend this pad holder. Does an excellent job keeping the pad secure and in place. No more shredded pads since. Bonus: no leaks on the floor. It’s so practical and so helpful.

Pretty Good But Not Perfect!
Size: 28'' X 34''
I have been using two of these frames for my miniature poodle puppy for almost a month now and while they are useful, they could be improved. The size of the frames are great for our miniature size poodle puppy and the Amazon pads that fit the frames absorb well without leaking underneath. The grips on the bottom of the frame keep it in place so it does not slide across floor. The frame hinges in the center so you can easily carry it through doorways. I am in my 60's so it is nice to be able to carry it to my work table in order to change pads while standing up.
My 4 month old 10 pound puppy can make a dinner plate size circle of pee onto the pad first thing in the morning. 4 large pees are easily held by the pee pads before needing to change it but we prefer to change the pads more often for sanitary reasons. Not sure if you have a very large breed dog that these would work for you. Our puppy likes going on these without hesitation so they are comfortable for him to walk around on and turn to find just the right spot!
Compared to other brands I have looked at this is a great value for money and worth a try to help with potty training your pup. Our puppy sleeps in an X-pen inside of our home at night and when we are gone so these help with keeping the pads where we want them. We have two - one inside X-pen and one by door where we are training puppy to go outside.
These frames are nice in appearance and seem like they will last but they are a little awkward to use compared to another brand I purchased which was more durable and easier to change pad. I ended up with these because other brands do not offer such a large size (28 x 34).
Our main complaints about these frames are:
1. The top frame is hinged and a little wobbly to manuever over the edges of the pee pads. Another brand, while a bit smaller, has a solid one piece frame that goes over entire pad in one step. This frame requires a three step process of laying pad down, pulling edges out flat and placing one side of frame down and then repeating on other side. There is usually a bit of adjustment that needs to be done and so requires opening and closing the frame again for adjustments.
2. The Amazon pee pads that fit this frame hold the pee well without leaking but have very thin tissue paper like edges (blue) that do not extend out far enough to make capturing the edges of the pee pad under the frame very easy to maneuver. It would be a game changer if the pads were made at least 1" bigger around length and width so edges are firmly held in place.
3. Our tiny 10 pound poodle pup is able to easily dig out edges of pad and tear it up. Not as bad as a loose pad by any means, but blue edges are exposed at side centers where frame hinges and there is no cover of edges (unlike a one piece frame) and the blue color seems to attract him. He can dig and loosen pad on any side because there is no way to hide and hold down all of the blue edges of pee pad.
I am still using these to potty train and, as I said earlier, these are way better than loose pee pads. I may shop for even larger size pee pads in the future to better lock down all of the edges without so much difficulty.
