4.4 S3 Versioning Demonstration

00:01

In this video

00:03

we will enable version ing on our bucket.

00:07

We will walk through a version ing example.

00:14

In our last video,

00:16

we created our first s three bucket.

00:19

We uploaded an object to our bucket

00:22

and we made our object accessible from the Internet.

00:26

In this video we will enable version ing on our bucket.

00:30

Then we will upload new objects to our bucket to demonstrate version ing.

00:36

So

00:37

as a review,

00:39

what does very thing do for us?

00:41

Version ing enables us to maintain multiple versions of the same object within our s three bucket.

00:49

Essentially, a new version could be something as simple as an update to an existing file.

00:56

This concept is better explained by an example.

01:00

So let's walk through a demonstration of version ing.

01:04

So from the console, let's type s three to get back into our bucket and cyber very rocks.

01:11

Let's click on our bucket,

01:15

then click properties.

01:17

Then we choose version ing

01:19

and then enable version ing.

01:23

Finally, we click save

01:27

version. Ng is now enabled on our bucket.

01:30

Now let's upload a new object to our bucket.

01:36

I have already created a test file called version example dot text

01:44

When we click on the file, we can see its properties

01:49

Notice the file size is about 71 bites.

01:53

And here is the girl that is assigned.

02:00

If we click show,

02:01

this is where we can see the different versions of objects within our bucket.

02:07

Notice the version I D. That A. W s has provided for this file.

02:12

It shows us that this is the latest version.

02:16

Also, you can see that our original object has a version I d off. No,

02:23

this is because we uploaded this object to our bucket

02:27

prior to enabling version ing.

02:30

So

02:30

let's click back on our new object to make it public, so that can show you the file contents.

02:38

If you recall from our last lesson,

02:40

files uploaded to a bucket are private by default.

02:45

So here is our example File

02:49

is just a simple text document that says Greetings one and all.

02:53

Cyber Harry is one of the coolest sites ever.

02:58

Now let's say that we want to add an update to this file,

03:01

but keep the same file name.

03:04

Here's how version ING helps us.

03:07

First, let's update our test file,

03:15

been safe and uploaded.

03:23

So now we have two versions of the same file

03:27

A W s indicates to us which is the latest version

03:31

and has assigned a new version i d.

03:42

The latest version is the file that are Earl will point to.

03:52

But when we click the Earl notice that we get an XML air,

03:58

remember, we have to make our objects public.

04:05

A W s tells us that it was a success.

04:10

Now we click our object again

04:12

and we could see the updated version of our file.

04:15

So what if we wanted to get rid of the old versions of our file?

04:18

How would we accomplish that?

04:23

Simple.

04:25

We just click on the old version of the file

04:28

Goto actions

04:30

click Delete

04:32

A. W s warns us that this is a permanent action.

04:36

So we then

04:39

just click delete.

04:41

And now the old object is going.

04:45

This is actually a good use case for combining M f a with version ing

04:50

that way on Lee. Someone duly authorized would be able to delete objects from our buckets

04:59

for more information,

05:00

visit the AWS documentation

05:03

and perform a search for managing objects

05:06

in a version ing enabled bucket

05:11

learning check.

05:15

How does version ing assist us

05:17

version ING enables us to maintain multiple versions of the same object within Rs three bucket.

05:27

How do we enable bucket version ing

05:30

from the console? We click on our bucket,

05:32

then click properties and then select enable version.

05:39

Once I upload a new version of my file, will others be able to see it on the Internet?

05:46

No.

05:47

When we upload a new version of an object, we will need to click make public

05:53

to enable it to be visible on the Internet.

06:00

In this video,

06:02

we enabled version ing on our bucket,
