Playing with ElastiCache - 2

In the previous post we setup a basic Lambda function that wrote to Redis. I updated the function to log some Cloud Watch metrics.

Playing with ElastiCache

I have never used Elastic Cache yet. My caching use cases were solved either via an in memory cache or a hosted cache. I finally got the chance to venture beyond - to cloud caches.

Playing with the Paths of Step functions

AWS Step Functions work by moving from one state to another state. States need a way to communicate with each other - DATA needs to be passed between them

Step Functions - AWS Service Integrations 2

In the previous post we successfully executed dynamo db, sqs and sns interactions directly from step functions. I wanted to try some tweaks to my state machine.

Using Lambda To Trigger a State Function

So I took the Hello World Step function example and wanted a Lambda to trigger the execution

Triggering Lambda on Schedule

I had a requirement recently where I needed to run a Monitoring code hourly to gather and plot some stats. With monitor duration of 1 second and total executions of 24/day, serverless seemed to be the way to go. However Serverless being an event driven world, I needed some way to trigger my Lambda.

Serverless - Lambda to publish to a stream

In the last post we started with Hello World Lambda - one that was driven by S3 events to write to S3. I wanted to attempt to use Lambdas for transformations. i.e. convert my file data in S3 to a stream.

Serverless - My delayed transition

The tech world has been moving away from servers for quite some time. While I was introduced to Lambda a few years back, I was hesitant to leave what I knew and jump into this new style of development. My initial experiences left me feeling Lambda is expensive, Lambda cannot replace having your own server up all the time, Lambda is for niche use cases etc.
