00:00:01,066 --> 00:00:04,700
We have seen the advantages of web apps and how great they are.

3
00:00:04,900 --> 00:00:08,700
But it doesn't mean that this coin doesn't have a flip side.

4
00:00:09,100 --> 00:00:12,666
There are just so many web apps available on the marketplace.

5
00:00:13,066 --> 00:00:16,633
There are so many clones of of some of really good ideas,

6
00:00:16,633 --> 00:00:20,200
and also many clickbait applications which turn out to be

7
00:00:20,200 --> 00:00:22,600
nothing but endless ad boards.

8
00:00:23,000 --> 00:00:28,400
And unfortunately, even that market is showing no signs of stopping at all.

9
00:00:28,966 --> 00:00:32,400
And while the liberty of choosing the app is still in the

10
00:00:32,400 --> 00:00:36,733
consumer's hand, all of these apps are being hosted

11
00:00:36,733 --> 00:00:40,733
and they are generating traffic occupying physical memory

12
00:00:40,733 --> 00:00:43,366
and storage in some of the data centers.

13
00:00:44,000 --> 00:00:47,900
While working with VMs, it is pretty common to have issues

14
00:00:47,900 --> 00:00:51,566
where the application was working smoothly on developer environment,

15
00:00:51,566 --> 00:00:54,533
but it was a train wreck on Ops machine

16
00:00:54,533 --> 00:00:58,033
or even worse, it crashes on the client machine.

00:00:59,166 --> 00:01:03,133
Since we have transitioned from waterfall to agile and agile

19
00:01:03,133 --> 00:01:07,366
to DevOps models, updates are rolling out faster than ever.

20
00:01:08,066 --> 00:01:12,300
Even if you are unaware of these models, just ask yourself this,

21
00:01:12,300 --> 00:01:16,833
how often did you receive updates for software 10 years ago?

22
00:01:17,100 --> 00:01:21,733
And how often a year do you update the Facebook app on your mobile?

23
00:01:22,566 --> 00:01:26,100
While faster updates are good for businesses and consumers,

24
00:01:26,100 --> 00:01:29,633
it brings huge responsibilities on system admins

25
00:01:29,633 --> 00:01:33,733
to make sure none of the updates compromise the stability of the app.

26
00:01:34,133 --> 00:01:37,266
And to reduce downtime as much as possible, we

27
00:01:37,266 --> 00:01:39,666
we end up using even more VMs.

28
00:01:40,566 --> 00:01:44,066
All of these Internet enabled application and rise of data

29
00:01:44,066 --> 00:01:48,100
science is generating huge amounts of data and populating up

30
00:01:48,100 --> 00:01:51,333
thousands of servers every day with databases.

31
00:01:51,833 --> 00:01:56,800
Overall, the usage of VMs have just increased significantly

32
00:01:56,800 --> 00:02:00,100
due to adoption of web apps and microservice models.

33
00:02:00,633 --> 00:02:04,600
And as you might have imagined, it has resulted into nothing

34
00:02:04,600 --> 00:02:07,700
but forests of service all around the globe.
