Transcripts
welcome today we are doing a bit of a
heavy topic which is
S3 it's a big one so back land we're
going to be diving into this one maybe
take some notes I would recommend it S3
is a very important part of AWS and we
are having a look so let's get into it
what is
S3 great question S3 stands for simple
storage service going to say it again
simple storage service
this guy and you can think of it as kind
of like cloud storage similar to Google
Drive but more for businesses so it can
handle infrastructure maintenance
security all that good stuff so that you
can just store what you need to store
it's a serverless service which means
that it will automatically scale up and
down depending on what you need and it
can store unlimited data and all sorts
of different formats accessible from
anywhere in the world wild so how does
S3 actually work well you can see in
here that we have a bucket and that
bucket has a name now with S3 we store
all of our data in these buckets in each
bucket you can always see the logs of
who has accessed it and who has access
to its content and you can add
permissions to it so you can lock it
down so that no one can see it or
perhaps remove or add item to the bucket
you can create permissions around that
and then you also need to choose a
geographical place where your bucket is
actually going to be where you can
access that data so in here you can see
that we have our bucket it's got a
little location tag it's got a lock on
it for our security it's got all of the
different things that we're going to be
checking in that bucket but it's also
got a very unique name now the name of
the backet always needs to be
distinctive and something that hasn't
been used before each AWS account allows
you to set up 100 buckets and once
you've created your bucket and you
selected the region of your bucket you
cannot change that region also if you
end up putting more than 100,000
different objects into your bucket then
you can't remove it using the S3
console even worse if virgine is turned
on then you can't remove the S3 bucket
through the AWS command line interface
now these all might seem like well what
have we even talking about here what do
these mean but that all become clear the
main thing is that if you fill up your
backet too much it becomes very
difficult to remove wherever you decide
to put your bucket initially
geographically that's where it stays
it's got to have a unique name and you
can set your permissions on it to who
can access edit or even view the data
that's in your bucket now your bucket
can do all sorts of cool things aside
from just store data it can actually
even host static website which is very
cool now we can access all of the
objects that are within our bucket by
using keys and that's how we can
identify each object or file or whatever
it is that you want to store in there
with that unique key so within S3 we
also have a bunch of different storage
classes so you think the S3 is just this
great bucket but actually no it's like
having all these buckets in different
colors and shapes and sizes and you got
to work out which one is best for you so
let's have a look at all the different
storage classes that are in Amazon S3
starting with S3 standard it seems like
a good place start so S3 standard is for
your frequently accessed data that
things you accessing more than once a
month with millisecond access a great
example is things that might go up on a
website videos or photos that you want
to put on your website data analytics
maybe even a few lightweight backups
next is standard IIA a standard IIA is
for infrequently Access Data these are
things that you accessing no more than
once a month I would say more for backup
and Disaster Recovery type thing number
three is one zone IIA this is data that
can be recreated if it's lost but it's
accessed way less frequently again
millisecond access here so very very
fast same as the other two this is for
your secondary backups your copies of
copies easily recreatable data number
four is intelligent tearing this is for
data with unknown or changing access
patterns because it will move data
between different tiers depending on how
often it is accessed how cool is that
for example if you have YouTube and all
the videos on YouTube they have
different access depending on how
popular the video is so if one video is
only getting you know a view a day or a
view a week or a view a month compared
to a video that's getting millions of
views and hours then they're going to
have different types of storage because
one of them needs to handle way way more
than the other and this is where
intelligent teering comes in happen next
we have Glacier instant retrieval this
is for your long-term archive data that
is accessed maybe once a quarter and you
still need to get it within like
millisecond this is the lowest cost
storage option for your long live data
this might be good for situations where
you need to access this sort of data
quite quickly but not very often so
maybe analysis compliance or other
business purposes then we have Glacier
flexible retrieval which used to be just
S3 Glacier and this is for your much
longer term backups so with flexible
retrieval you can only access these
really you should be planning for once a
year and the retrieval time instead of
it being milliseconds it's now minutes
or even hours this is good for your
backup and Disaster Recovery where is it
really matter so much about the cost but
you need that backup and you're okay
with it being retriev reved In
Minutes last we have the glacier deep
archives which you're thinking I thought
we'd already got there I thought that
was the biggest most longest one that we
just did but no it gets even deeper this
is the real long-term one again maybe
accessing it once a year once or twice a
year but it's got a retrieval time of 12
hours so this one is going to be cheaper
but you really can't expect to get
anything back in a hurry it's for
digital preservation historical records
that sort of thing where you need to
keep it but you're really not going to
need to access it that so that's all the
different types of storage classes that
we have let's talk a little bit about
the features of
S3 starting with access management and
security a very important one these
three buckets and objects are private by
default but there are lots of tools and
features that help to enable its
security these include S3 block public
access Imam which we've talked about in
previous videos bucket policies S3 end
points and so well next up is Amazon S3
versioning versioning just means that
you're helping to keep track of the
changes that have been made so you might
have multiple different versions of
something so that you can look back and
see oh that's where we started and then
we made these changes and now it was in
version two and then we made these
changes announced in version three so
that you can actually keep track of when
these changes were made who made them
whether they were good or not and you
can always rever back to previous
versions if something isn't working it's
really good for safeguarding against
accidental changes and deletions as you
can imagine and you can always retrieve
those older versions if you really need
to next is the S3 static website this is
simply for hosting static websites on
Amazon S3 it's a really easy cost
effective way for simple websites to be
hosted then we had S3 replication which
is about automatically copying files
from one bucket to another another
bucket this is great for your backups of
your buckets in case of damage or file
loss or something goes wrong something
gets deleted or over around or whatever
it is then at least you have a backup
that you've made using
replication then S3 encryption which is
all about security encrypting things
encryption is really useful for data
when it's in transit which is when it's
been sent somewhere so it's going across
the internet which is a wild place by
the way could constantly be attacked
it's like going down a highway where
there's all these like people that are
just trying to rob your car so it's
useful for that but it's also useful for
at its destinations either where it
needs to go or where it started from it
keeps your data safe there so whether
it's on the move or whether it's where
the end destination is or the start
destination uh it's going to help with
both of those places then we have S3
transfer acceleration which is about
speeding up your file uploads and your
file downloads this is great for very
long distance transfer of large files
and enhancing your data transfer speed
to summarize everything that we've
talked about today with S3 the best S3
option really depends on your storage
patterns and how often you are accessing
that data the options include standard
S3 S3 intelligent tearing S31 Zone IIA
glacious storage both instant and
flexible and the glacia Deep archive S3
is a huge topic we've only just kind of
gloss over the very high level things
but the best way to learn is to get in
there and actually start looking at some
stuff so I hope this was a good overview
to with your appetite and get you
started and all the best we'll see you
in the next
