This course provides the best Amazon Web Services (AWS) tutorial for beginners to learn about AWS cloud services.

Learn about the core AWS's services like compute, storage, networking services and how they work with other services like Identity, Mobile,  Routing, and Security. This course provides you with a good grasp an all you need to know of AWS services.

This course has been designed by three AWS Solution Certified Architects who have a combined industry experience of 17 years.  We aim to provide you with just the right depth of knowledge you need to have.

Easy to read and very succinct ! Loved this course. Its better than most other courses  out there that are either half baked or way to detailed. 

Excellent,  time and money well spent on this. 

Richard Guajardo

Got what I was looking for. I used this for my interview prep with AWS. 

Worth it !

Tammy Rogers 

Loved all the architecture diagrams. It really helped in understanding how each service would be used. 

Pretty detailed.

# What is Lambda?

The evolution or  timeline of Lambda  looks something like this: 


`On-Prem DataCenter –> IAAS –> PaaS –> containerization/Docker –> Serverless`
 
Lambda is a compute service where you can upload your code and create a Lambda function. AWS Lambda takes care of provisioning and managing the servers that you use to run the code. You do not have to worry about operating systems, patching, scaling etc.

It is essentially described as an event-driven compute service where AWS Lambda runs your code in response to events. These events could be changes to the data in an Amazon S3 bucket or an Amazon Dynamo DB table. 

Lambda events can trigger other Lambda events or call other AWS services like SQS or SNS.

# Why use Lambda? 

1. The Lambda runtime is fully managed by AWS. Once a function is uploaded and configured, Lambda is responsible for managing the resources required to run the code. 
1. Developers are free from the traditional overhead of configuring and maintaining server instances. 
1. Lambda will immediately scale to meet spikes in demand. 
1. Lambda is cost-effective as you only pay for the computational resources used. This is, of course, true for other AWS compute services, but the cost model for Lambda is more granular than EC2 for example, with resources being charged per 100 milliseconds.
1. Lambdas event-driven model means you can integrate nicely with a range of AWS services, but still ensure loose coupling.
1. It's very low cost. The first 1 million requests are free and you have to pay 0.20 per 1 million requests thereafter!!
