Hi Raj, I read in multiple articles that Lambda runs on Firecracker, which is an LVM, and which runs on EC2 as a backbone, rather than containers (ex. ECS). I am referring to the underlying infrastructure behind the scenes, not the possibility to invoke lambda through an ECR-Container (instead of a Zip file).

superb sir my problem resolved I make it 200 now it is working

Great 👍

Hi Raj, your content is super awesome. Plz keep on making more such videos.

@lzoneonethreethreeseven8046 2 года назад

are lambda functions always scaled automatically when many requests come in? have lambda functions an integrated load balancer or is it vital to provide one that targets it in every case?

@amitk5088 3 года назад

Thanks a lot sir

@cloudwithraj 3 года назад

Most welcome

that is good explanation what is difference between provisioned concurrency and snap start

@anhquocnguyen1578 10 месяцев назад

your explanation is very well. keep up your amazing work, pls. thank you

@cloudwithraj 10 месяцев назад

Thanks a lot!

"Reserved concurrency" therefore means "max concurrency". "provisioned concurrency" means "number of always running instances"

@cloudwithraj 2 года назад

Correct!

thanks!

I am hitting an lambda API from react code repeatedly, so the problem is the sequence I am sending the request ,response are not coming sequentially, response of recent request comes faster than my previous request. So how to configure throttle to handle this scnerio

@Cedielagekohaha 3 года назад

If you want to handle the request sequentially then you need to use FIFO queues backed by Lambda. Regarding throttling, you can configure your queues to have a redrive policy (retry) whenever the request fails. If the maximum redrive policy is reached it will be rerouted to DLQ .

@biswajeetsethi7689 2 года назад

Hey Sir. I understood how Lambda gets the container that is behind the scene. But if we go to the system level. Who provides container service to Lambda ???

@cloudwithraj 2 года назад

Hey Biswajeet, AWS firecracker provides the underlying container. Now, you can also create your own container - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-HNm6jU_AUbE.html

By default the unreserved account concurrency is 1000 and if I raise a request to change it. say I want it to be increased to 2000, AWS is going to charge me for that or not? If I reserve concurrency for one lambda function to 200, does it mean that function is always going to use that limit and never go beyond that limit?

@cloudwithraj 4 года назад

You will NOT get charged if you just increase the limit. You only gets charged on what you use. If you allocate concurrency limit for a lambda to 200, it will never have more than 200 concurrent executions (Your assumption is right for this one). Thanks for watching!

@cloudwithraj 3 года назад

@Shanmukh Meesala You will get a throttling error (error code 429), and you can retry.

@amitk5088 3 года назад

I am getting this issue

@amitk5088 3 года назад

can you help me

@takethree1 2 года назад

I have 30k SQS msg/min for Lambda to process. Do I need provisioned concurrency? increased ?

@kavyasuresh7423 2 года назад

Did you solved this problem?

@ziadirida 4 года назад

Isn't it true that lambda is great because you pay nothing with serverless when you are not using it. But with provisioning, this advantage goes away.

@Conlexio 4 года назад

there is also an advantage for simpler projects in that you don't have to manage and maintain servers too I guess

@cloudwithraj 4 года назад

Yes, you do pay extra for provisioned concurrency. Best practice is use provisioned concurrency based on schdule if you know traffic pattern, or you can make it scalable based on traffic.

@Cedielagekohaha 3 года назад

Everything depends on the application use-case. If you have strict response latency SLA then having a provisioned concurrency is great.

@amitk5088 3 года назад

Function is throttled Your function cannot be invoked while the reserved concurrency is zero.

@cloudwithraj 3 года назад

Your function has no concurrency left. Either all other lambdas are using the concurrency available in the region/account or the concurrency of the lambda in question is set to zero. Change it to some positive value and then retry
