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
