Schedule AWS Lambda Functions Using EventBridge

[@MarcHoeijmans]

Great video, your demo covers exactly what I was looking for. Thanks!

[@rahulkr2000]

Perfect explanation. To the point, without any Bakwas. Loved the simplicity in your video. Keep it up.

[@BI-Rahul]

Thank you very much, Perfect timing for the video, Was just looking on youtube how to schedule Lambda Function daily.

Thank you so much , Most useful series for Java implementation

Great job! It helped a lot!

Great video ! QQ - Can you suggest how to trigger/run the code which is in github using lambda please?

[@saswatsenapati7870]

I had a question in mind lets say i have use case where i have to schedule my rule to invoke lambda for every 5min.
Now , the lambda gets checked if we have task every 5min by pinging an endpoint of lambda.
Now the question is, due to pinging every 5min arent we keeping the lambda alive and doing some compute (of checking task) every 5min, which defeats the purpose of using lambda. ???
We are using it as ec2 machine.

[@AjayWadhara]

No, I would say this is the perfect use case of Lambda.
Even if you are not able to perform the task, your are charged for those few seconds.
When you say Lambda alive, that doesn’t mean you are being charged for that. What that means is Lambda won’t perform the Cold start which is actually good.
My suggestion is move your task to Lambda from EC2. Also, use EventBridge for invoking Lambda.
Hope this helps 🪂

if you select
Run at Regular Rate
and the settings is 7 Days
at what time do they run?
at what point does the counting of 7 days start?

[@AjayWadhara]

Best way to schedule is to use cron expression. Go to crontab.guru and create a cron expression and use that

But where it will show output of the code

[@realnileshpawar]

Is it a good time to switch from frontend developer to AWS solutions architect?

[@AjayWadhara]

I would say frontend with AWS, rather than AWS Solution Architecture.
There is more demand for people with Fronted + AWS

[@hardikbehl2792]

I have a use case in which I want the lambda to execute only once based on the time selected by the user. I tried .withTime(java.util.Date) function but it is not working as expected. rather it's triggering the lambda function instantly even if i provide the timestamp of next year. Is there a way in which I can achieve my use case here

[@AjayWadhara]

Did you use event rule properly. If you are setting as per the user input, you must be using SDK.

[@hardikbehl2792]

@@AjayWadhara Yes, I was using the java SDK but it was trigerring the lambda instantly. Now rather than pushing an event, I am creating a rule with schedule pattern and passing a cron expression signifying the timestamp I want the lambda to run it. Now the required functionality is being achieved. The only drawback to this approach I identify is that AWS allows 300 rules per event bus, so I am thinking of deleting the rule once the lambda is triggered since the rule ARN is being given as input

[@AjayWadhara]

@@hardikbehl2792 If you are selecting per user, This is the best option.
How much os your user base ?
Also, did you check if 300 is the soft limit or the hard stop ?
