-: So let's have a look at the service quota service.
So in here you can look at all your quotas
within your accounts and the grouped by services
that you have already used in your accounts.
So if we go back to our example,
if you look at Lambda, for example,
we can look at concurrent execution, as I said.
And so this is the maximum number of events
that functions can process simultaneously
in the current region.
The default value is 1000, okay.
But as we can see,
we can adjust it and request a quota increase
if we needed to, okay.
Directly from within the service quota UI.
But you can also create an alarm on top of this quota.
So for this, there is a monitoring,
and this shows you over time,
the value of the actual value of concurrent execution. Okay?
And at the bottom you have Amazon CloudWatch alarms.
So we can create an alarm on this and say,
"Hey, when the alarm threshold is 900,
then this is alarm for concurrent Lambda executions,
then please activate this alarm."
Now the alarm is created and you can configure actions
directly from the alarm.
So the alarm is right here.
And you can edit on the top, right corner,
the actions and say,
"Hey, when you are this," oops, let's go again.
Edit, and then scroll down, click on next.
Then for actions, maybe you send a notification
when you are in the alarm state,
choose an existing SNS topic being my demo topic.
And then I would receive a little notification by email
when this alarm is being triggered.
So this is quite handy.
But as you can see,
from within this entire service quota UI,
we can monitor all those services within AWS
and all the limits available within them.
Which is very, very handy.
And for every single limits you can, for many limits,
you can request a quota increase, okay.
And the one that respectable and create a CloudWatch alarm
on top of them. Okay.
And finally, if you wanted to do the same
in Trusted Advisor,
I will just quickly show you how it works.
And so in Trusted Advisor, you can click on service limits,
and this will give you the list of all
the service limits available
from within Trusted Advisor
but is not all the limits obviously available
within your accounts.
And they're already pre-configured.
So as you can see,
this one is a check that will check for the usage.
If you have more than 80% of your auto scaling group limits.
Okay? So this is a pre-configured check
and you can create an alarm on top of it if you wanted to,
but this is less flexible and less complete
than the service quota service.
So that's it for this lecture, I hope you liked it.
And I will see you in the next lecture.
