Additionally on the messaging. If payloads are large it is a recommended approach to pass a reference to the s3 storage that contains the payload and not to pass payloads across the transport layer. Of course depending on the size of the payload it may be a negligible consideration. The value of passing a pointer to payload and particularly for real time message velocity is you don't want to tie up your transport ducts with latencies due to large Data Sizes

Best in the entire youtube, professional well done....👍👍👍👍👍..please add more examples....thanks a million ...got a lot of clarity

[@WinTheCloud]

Thank you, I really appreciate your support! Here are two new patterns I published since this video: - Orchestration with State Machines: kzbin.info/www/bejne/hoC8ZZePrNhgodE - Event Sourcing: kzbin.info/www/bejne/hKfYi6J6m9qieMU I hope you find them useful as well :)

Much appreciated!

Good one.. Keep up with all good work you are doing to share such a quality content for system architect...

[@michaelalexander8626]

with respect to the circuit breaker pattern depicted in this video. first, as an alternative to lambda's fronting the calls and managing the call to the external service by reporting errors this can be managed by service buses. Not to say that we need a service bus in all use cases but that a service bus does exist to manage communication with retries and routing already built in as an option

[@WinTheCloud]

Thank you for this, which Serverless service bus would you recommend ?

[@lauraquiros7810]

Great material!!.. will be nice to know about "Webhook Pattern" Thank you

[@WinTheCloud]

Thank you! It's on the list, will be released pretty soon ;)

[@rodoherty1]

Excellent video, iLyas! Thanks!

[@WinTheCloud]

Thank you too, my friend!

Good one. Nowadays serverless is everywhere

[@khaledghamgui2581]

I think serverless have a lot of potential but all the content I have seen until now are just scartching the surface. Great video !

[@GilluanFormiga]

Amazing!

[@WinTheCloud]

Thank you! Cheers!

[@tusharanand4059]

Have been searching for use cases approach, finally got this great one. Can we be more detailed/deep dive in the next videos

[@WinTheCloud]

Sure thing! I'll try to bring more real-life use cases as well

[@rohitturambekar5457]

200th like is mine ;-)

[@cristiannechita2032]

Hey - nice video (might be late for the show). The only thing I would say is that instead of the approach you suggested for the router pattern I would use the Pub/Sub pattern with the addition of Subscription Filters. You will have all the benefits of pub / sub (direct service integration where it is supported or have a lambda in front of SNS that will do the routing).

[@WinTheCloud]

Love it. I can see myself using that as well

[@farukm7627]

Thanks again, Ilyas for a very informative video.

[@WinTheCloud]

My pleasure buddy!

This is great! thanks for sharing!! Have a couple of questions on the Router pattern: 1. In S3 I could create notifications to each Lambda based on the prefix and/or the suffix (like .csv, .jpg, .txt, etc), in this case, does it count as a Router pattern? so that if any other type of file is required, we develop the Lambda function to process that file and create another notification in the bucket configuration. (Although I know this pattern won't work if the Router needs more detailed information about the file, I think it could make things simpler if we only focus on file extensions or prefixes) 2. Could we set a pair of Queues (message/main queue and DLQ) for each Lambda and put the main Queue in the notification of the bucket? I think this way helps us to be more detailed about where the error occurred and focus on that one. Already subscribed to your channel, keep it up!!

[@WinTheCloud]

Hi Mario, 1- Your assumption is correct, using S3 rules to trigger separate lambda function is an implementation of the Router pattern. In the example I presented, I had to read the file and parse the schema, that's why I went for a Lambda function. 2- This is correct as well, divide and conquer is a concept that works very well with event driven applications. You can use the DLQ to retry later, or simply debug & analyse the failures. Thank you for your support!

[@mariomerco]

@@WinTheCloud thanks so much!!! Keep it up!!

[@spaciouscloset459]

Thanks for the great content. Could you teach an end to end migration from onprem to AWS containers/serverless?

[@WinTheCloud]

I think a lot about this question, but given the amount of parameter that go into every use case, I have to find the right one. Don't worry though, it's on the top of my list.

Hey great video 😍. Is it possible to share the ppt?

[@VaibhavNitturkar]

Great video. Did you publish the webhook pattern in next part?

[@vamsiakhumukhi9582]

You're a genius!!!

I'm humbled :)

[@oswaldoantoniomartinezreye4561]

Awesome material! Is there a way to find more about the patterns, like more references about them? Thank you

[@Ironighte]

On 8:20, the dynamodb docs say ttl record delition will happen within 48 hours depending on the size of the table. So your deletion ttl time won't be as accurate as needed for the circuit breaker to retry when it should. It could take up to 48 hours for a retry. Is it an issue? It depends if the request needs to be done in a timely manner. What alternative could we use there that guarantees deletion at that specific time?

[@jackishere]

Very good one - Go for the 2nd !!

[@WinTheCloud]

That's the plan!

[@jackishere]

@@WinTheCloud ideas: immutable infrastructure, serverless backbone , serverless service mesh , lambdas isolation...

[@waleedahmad2012]

awesome video iLyas, can you quickly explain how can we bind a dynamoDb table to single microservice. what i mean by that is usually creating flows, dynammoDb is shared and any lambda can access it. How are you only restricting it to only 'Users microservice' in the strangler pattern.

[@WinTheCloud]

Great suggestion! So usually I'd recommend using IAM roles to give your Lambda access to the dynamoDB table. Using CloudFormation for example, you can build a template that creates: - A DynamoDB table - A Lambda function - An IAM role or policy that gives access to the said dynamoDB - Assign the role/policy to the Lambda You can find a few templates that do exactly this on Github, here is one for example: github.com/nrdio/sns-lambda-dynamodb-cloudformation-example/blob/master/cloudformation-template.yaml

In the first Strangler pattern example, if the database is RDS, what can replace DynamoDB Streams?

[@edziomy]

Why SNS Topic is sending out "User Created" event directly? A specialized Lambda function that creates user entry should notify with "User Created" when write to DB succeeds or...?

[@WinTheCloud]

Your suggested variation is correct. A Lambda can write to a Dynamodb which will trigger another Lambda through Dynamodb stream... As I mentioned at some point in the video, these patterns have multiple variations and should be adapted to your use case. But I try to keep things simple for this series, I can probably devote an entire video to each one of these patterns...
