In this video, we are going to talk about a cost management.
During the course, we will provision and deploy lots of aid services on a soulless cloud environment
and these are mostly free services with the PDT account.
Then I prepared this course.
Ada didn't charge me any amount of money from Ada Lovelace with definitive account.
So if you follow me with pretty record, you don't get charged.
But you should consider and careful that these are paid services that come with the cost.
So let me show my billing result.
Here is my cost and usage for our course development.
As you can see that I didn't charge any amount of cost for my usage and here is the multi-tier usage
of the services.
As you can see that I have sent lots of requests to the services when preparing this course.
And all these services has zero cost of me with following the detailed account.
See that I have almost 300 request usage for a lambda 200 request for a case and these are spending
very low amount of the limits.
You can also see the place finisher account usage limits under the second column here, the limits in
here, and we only use very low amount of the limit.
So you can see this detail page into the cost management module than you can access from your dashboard
page in the management console.
But you should log in with the root user.
Only root user can see these details.
Now I would like to show you a place visitor account limits.
You can also see a little account limits from the official website.
If you open the a free tier account page, you can scroll down and see in here.
As you can see that there is some filters according to type.
If you click the always free, you can see that really good amount of free usage limits giving.
With the free tier account which is free to account, we can use more than 100 products for building
applications and most of the services allow a good amount of users depending on the product.
But I can say that these free tier account is really, really sufficient to develop something like average
applications on a list.
So infinity, the account details.
If you click the always free checkbox in here, we can see that 25 gigabyte dynamo DB 1 million Lambda
Requests, 1 million Amazon SNS request and one Terabyte, Amazon Cloud Pro and so on.
So these are good amount of numbers that you can create your own startup application with this three
tier account and the power of the high scalability and high availability.
So if you come back to our slide.
So now we can talk about to be careful when following this course.
I always clear resources after finish the section or leave from computer at this stage.
I would like to emphasize the quote from the ADA CTO Werner Vogels about the cloud usage and global
warming.
Why don't Google set that turn off the lights before leaving the room?
So you can think that if you leave from your computer and shut the light off, that means you also shut
down the resources.
He's saying this for the unused resources on the cloud, but from our course perspective, we can also
follow this code because we don't need to stay live on production.
We can think that we are going to prepare demo session with your customer and you should show the serverless
applications during the customer presentation.
And after that we should shut down the resources since new customer session arranged.
Please consider this and clear all resources after you finish the work at that day or you are leaving
to your computer.
This is very important and the second consideration is don't share a place, account, sub user or API
access K with anyone.
So this is another important topic that we should consider that a s account has sub user and API access
case and we should not share this information for anyone or any time period.
This is so important rule to avoid unexpected costs from a w is when you share this, that means you
allow someone to create resources on a w.
So please consider these warnings.
And if you follow these principles, you won't be charged any costs during the course.
Now we can start our course.
