 '''CloudWatch Alarms''' allow you to set alarms that notify you (e.g., via email) when particular thresholds (you set) are hit.
-'''CloudWatch Events''' helps you to respond to state changes in your AWS resources. When your resources change state they automatically send events into an event stream. You can create rules that match selected events in the stream and route them to targets to take action. You can also use rules to take action on a pre-determined schedule.

When your resources change state they automatically send events into an event stream. You can create rules that match selected events in the stream and route them to targets to take action. You can also use rules to take action on a pre-determined schedule. For example, you can configure rules to:
 * Automatically invoke an AWS Lambda function to update DNS entries when an event notifies you that Amazon EC2 instance enters the Running state
 * Direct specific API records from CloudTrail to a Kinesis stream for detailed analysis of potential security or availability risks

-'''AWS Lambda''' lets you run code without provisioning or managing servers. You pay only for the compute time you consume - there is no charge when your code is not running. With Lambda, you can run code for virtually any type of application or backend service - all with zero administration. Just upload your code and Lambda takes care of everything required to run and scale your code with high availability. You can set up your code to automatically trigger from other AWS services or call it directly from any web or mobile app.

-AWS Lambda is a compute service where you can upload your code and create a Lambda function. 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. You can use Lambda in the following ways:
-* As an event-driven compute service where Lambda runs your code in response to events. These events could be changes to data in an S3 bucket or a DynamoDB table.
-* As a compute service to run your code in response to HTTP requests using Amazon API Gateway or API calls made using AWS SDKs.

-What is Lambda? It encapsulates all of the following for you:
-* Data Centres
-* Hardware
-* Assembly code/protocols
-* High-level languages
-* Operating systems
-* Application layer / AWS APIs

-* Languages Lambda supports (as of February 2017):
-** Python
-** Node.js
-** Java
-** C#
-−
-* Pricing
-** Number of requests
-**: First 1 million requests are free. $0.20 per 1 million requests thereafter
-** Duration
-**: Duration is calculated from the time your code begins executing until it returns or otherwise terminates, rounded up to the nearest 100ms. The price depends on the amount of memory you allocate to your function. You are charged $0.00001667 for every GB-second used.

 SNS is a web service that makes it easy to set up, operate, and send notifications from the cloud. It provides developers with a highly scalable, flexible, and cost-effective capability to publish messages from an application and immediately deliver them to subscribers or other applications.
-SQS follows the "publish-subscribe" (pub-sub) messaging paradigm, with notifications being delivered to clients, using a "push" mechanism that eliminates the need to periodically check or "poll" for new information and updates. With simple APIs requiring minimal up-front development effort, no maintenance or management overhead and pay-as-you-go pricing, SNS gives developers an easy mechanism to incorporate a powerful notification system with their applications.
