00:00:07,309  -->  00:00:13,049
Welcome back to Backspace Academy. I'd
just like to very quickly introduce you

2

00:00:13,049  -->  00:00:18,270
to the AWS for free tier. Now up until
now everything that we've done with

3

00:00:18,270  -->  00:00:21,900
these labs has been covered under that
free tier and we won't be getting a bill

4

00:00:21,900  -->  00:00:26,430
for it provided we deleted everything
after the lab we won't be we won't

5

00:00:26,430  -->  00:00:30,510
experience a problem there. So what I'd
like to do now is first of all show you

6

00:00:30,510  -->  00:00:36,570
how to get to the AWS free tier website
so you go to aws.amazon.com the AWS

7

00:00:36,570  -->  00:00:42,600
website and it's simply forward slash
free now what we can see is that there

8

00:00:42,600  -->  00:00:47,219
some things here there are free for 12
months some things are always free and

9

00:00:47,219  -->  00:00:52,230
trial so what that means is that if we
signed up for our account three months

10

00:00:52,230  -->  00:00:56,910
ago there are some things that are going
to be free for another nine months so

11

00:00:56,910  -->  00:01:02,250
they're only free for twelve months from
the time that you first opened your AWS

12

00:01:02,250  -->  00:01:08,070
account we also have some things that
are always free so provided we stay

13

00:01:08,070  -->  00:01:12,450
below a certain limit of that service
we're going to get that for free as well

14

00:01:12,450  -->  00:01:17,240
and that won't be affected by the twelve
month period at all we also have short

15

00:01:17,240  -->  00:01:23,220
trials of services as well now we we can
never look here and just have a look at

16

00:01:23,220  -->  00:01:27,299
the product category so I'll just click
on that so under compute we've been

17

00:01:27,299  -->  00:01:32,490
using Amazon ec2 and we'll be using
it quite a bit throughout this course

18

00:01:32,490  -->  00:01:40,409
and that will give you 750 hours free
for 12 months per month so what that

19

00:01:40,409  -->  00:01:47,070
means is that we can have 750 hours per
month of T2 micro instance and that

20

00:01:47,070  -->  00:01:53,100
will expire twelve months after signing
up for AWS now the big thing to remember

21

00:01:53,100  -->  00:01:57,990
is that this is only for a t2 micro
instance if you have anything bigger

22

00:01:57,990  -->  00:02:02,219
than that doesn't matter how much you
use you're going to get billed for it

23

00:02:02,219  -->  00:02:09,539
and also to consider is that a smaller
instance like the t2 Nano will not be

24

00:02:09,539  -->  00:02:13,530
covered under the free tier it is
specifically for the t2

25

00:02:13,530  -->  00:02:18,060
micro instance the other thing to take
into consideration if we're launching a

26

00:02:18,060  -->  00:02:23,490
highly available and fault tolerant
architecture where we're using say 2

27

00:02:23,490  -->  00:02:30,690
t2 micro instances that will double up
our our usage so instead of having 750

28

00:02:30,690  -->  00:02:34,980
hours of usage if we're using 2 of the t2 micro instances we're only going to

29

00:02:34,980  -->  00:02:42,989
be able to have 375 of those those hours
available so the more instances use the

30

00:02:42,989  -->  00:02:48,300
less hours you're going to have and the
same with our database service so either

31

00:02:48,300  -->  00:02:52,590
RDS with again we've used that as well
we're going to get 750 hours of that and

32

00:02:52,590  -->  00:03:00,269
that is again only going to be for t2 micro
and we storage in content delivery we're

33

00:03:00,269  -->  00:03:04,319
going to be using s3 a lot and again
we're going to get 5 gig of standard

34

00:03:04,319  -->  00:03:09,870
storage under that free tier so let's
have a look at the things that are

35

00:03:09,870  -->  00:03:14,760
always free
so under Amazon Cloud Watch so we have

36

00:03:14,760  -->  00:03:19,590
10 custom metrics and 10 alarms so
provided we stay below that that's not

37

00:03:19,590  -->  00:03:24,540
going to cost us anything and that
doesn't expire after 12 months so it's

38

00:03:24,540  -->  00:03:36,030
always free and DynamoDB 25 gig of
storage always free Amazon SES 62,000

39

00:03:36,030  -->  00:03:40,290
outbound messages per month provided we
stay under that for the month we're not

40

00:03:40,290  -->  00:03:45,930
going to incur a charge for that and we
also have trials so you need to be very

41

00:03:45,930  -->  00:03:50,370
careful with trials so for example with
Amazon Redshift that is a quite an

42

00:03:50,370  -->  00:03:56,280
expensive service so if you look there
you've got 750 hours of DC to large

43

00:03:56,280  -->  00:04:03,450
hours per month for 2 months but if your
account is already over 2 months old and

44

00:04:03,450  -->  00:04:08,250
you sign up for all you actually start
using redshift you're going to get

45

00:04:08,250  -->  00:04:12,269
billed for it and you're going to be
billed for quite an expensive instance

46

00:04:12,269  -->  00:04:19,890
as well. So that's the AWS free tier so what
I recommend you do is go to this website

47

00:04:19,890  -->  00:04:24,060
have a look around see what's free as
you're working through the labs if you

48

00:04:24,060  -->  00:04:27,270
have any any doubts about something
being free then just

49

00:04:27,270  -->  00:04:32,610
go to here and and check it out and I'm
sure it'd be fine so we do try to stay

50

00:04:32,610  -->  00:04:37,110
under this free tier throughout the
course but things such as buying a

51

00:04:37,110  -->  00:04:41,490
domain name will incur a cost so that's
all I want to say about that for now and

52

00:04:41,490  -->  00:04:46,699
I'll look forward to seeing you in the
next lecture
