when you create a function nappy natural
00:02
you require to choose a hosting plan for your function up,
00:06
let's see what the hosting plan is and what choices you have.
00:12
Microsoft offers three different costing plans for functions. Consumption plan,
00:18
premium
00:19
and dedicated.
00:21
When you create a function app, you required to choose one of those plans, as well as a storage account
00:28
that will be used to store the files and triggers for your function up.
00:33
Let's look at each individual plan and see how they differ.
00:38
The consumption plan is that the four plan that you can choose for the gradual functions
00:45
the consumption plans scales out and in automatically. But keep in mind that each execution has a warm a period that may impact the performance of your application.
00:56
The benefit of this plan is that you pay only when the function is running.
01:02
If your application is used irregularly, this can save you a lot of money because you don't need to pay for infrastructure. When it is not used,
01:11
you can coming go more people function naps on the same hosting plan if you are. If they are deporting the same region.
01:19
However, be careful with that because if you have many functions that consume resources concurrently, Europe may suffering performance
01:30
functions. Running on the consumption plan have Hartley meets for how long they can run
01:36
the default time out these five minutes and the maximum you can set istan.
01:42
This means that the execution of your coat needs to be complete before the time out expires, which does not allow you to have long running processes.
01:53
The consumption plan also does not allow you to vary the size of the execution environment.
01:59
You're limited to 1.5 gigabytes of memory in a single CPU core.
02:04
If you need more, you need to choose one of the other plans.
02:08
As I mentioned earlier, the consumption plan is the most cost effective plan, and you're built their execution and the amount of memory used by your function.
02:21
The premium hosting plan is similar to the consumption plan in a sense that it scares automatically to your needs.
02:28
However, the premium plan gives you more flexible choices in advanced capabilities.
02:34
With the premium plan, for example, you can have perpetual work instances that do not require startup time and improve your application performance.
02:44
You have also the option off unlimited execution time
02:47
and Severo instance, sizes that you can choose from.
02:53
The premium plan also allows you to have virtual network connectivity, which means that the access to your functions is restricted to the virtual network. This increases your security.
03:05
Of course, the pricing of the premium plan is different, and it is based on the number of course seconds and the memory Europe functions use.
03:15
The dedicated plan is intended for customers who have under utilized instances that are used for other APP service applications like Web apps. For example,
03:27
with this plan, you have the option to provide your own images images for your functions.
03:34
The dedicated plan requires many or scaling by default, which means that you need to be careful when there is unpredictable demand for your functions.
03:42
There is, of course, out of scaling option,
03:45
but you need to explicitly configure it.
03:49
The pricing of the dedicated plan is the same as for the other upset of ESOPs like Web ups.
03:57
One thing that you need to be aware of when using dedicated plan
04:00
is that if you plan to deport functions that require other triggers, then the http trigger like for example, Q or scheduled triggers.
04:10
You need to turn on the always on feature on the plan.
04:14
Else you risk that your triggers do not fire the function.
04:17
The default time out for the functions. Deporting the dedicated plan is 30 minutes, and, of course, you can configure them with unlimited time outs.
04:30
Let's finish with the visual showing how the hosting plans work
04:34
so you can have a single hosting plan that can cause multiple function ups.
04:40
Each function up can have multiple functions inside that implementing different functionality
04:46
once again, be careful with the resource requirements of each function and make sure that the resource is dedicated to the function up will serve the needs of your functions.
