00:00:00,000 --> 00:00:09,040
In this video, you'll learn about configuration management.

2
00:00:09,040 --> 00:00:14,160
In configuration management it's all about configuration as code where

3
00:00:14,160 --> 00:00:17,520
a configuration is defined in some configuration files.

4
00:00:17,520 --> 00:00:19,480
Let's show it again.

5
00:00:19,480 --> 00:00:24,320
In configuration management it's all about configuration as code where your

6
00:00:24,320 --> 00:00:25,639
configuration is defined,

7
00:00:26,639 --> 00:00:29,000
in some manifest files.

8
00:00:29,000 --> 00:00:32,959
The desired state of the managed assets is described in the manifest file,

9
00:00:32,959 --> 00:00:36,880
which can be compared to the current state of the managed assets.

10
00:00:36,880 --> 00:00:43,119
And the desired state normally is defined in a declarative configuration language.

11
00:00:43,119 --> 00:00:46,439
Configuration management can do different solutions.

12
00:00:46,439 --> 00:00:48,720
It can be push-based or pull-based.

13
00:00:48,720 --> 00:00:52,840
Some solutions are working with an agent, while other solutions are not.

14
00:00:52,919 --> 00:00:55,919
Configuration management is what comes after deploying physical,

15
00:00:55,919 --> 00:00:58,799
virtual or cloud instances.

16
00:00:58,799 --> 00:01:03,279
Infrastructure as code is focusing on solutions that implement an infrastructure

17
00:01:03,279 --> 00:01:04,839
in a declarative way.

18
00:01:04,839 --> 00:01:08,040
And that is often used in cloud environments.

19
00:01:08,040 --> 00:01:12,440
HashiCorp Terraform is a common infrastructure as code solution.

20
00:01:12,440 --> 00:01:17,040
But some configuration management solutions can do infrastructure as code as well.
