"microkernal" should be "microkernel".

Note from the Author or Editor:
Good catch! It's a common misspelling that I'm surprised no one caught.

"This book won’t make someone a software architecture overnight"

The word "to" is missing between "going" and "assume". Should be "...we're going to assume a baseline..."

```
public void assessDevice(String deviceID) {
...
DevicePlugin devicePlugin =
(DevicePlugin)constructor.newInstance();
DevicePlugin.assess();
}
```

last statement is `DevicePlugin.access();`, like it calls class static method, but I think it should be `devicePlugin.access();`, which calls instance method.

“Chapter 3” reference should be Chapter 7 - where architectural quantum is defined (page 92)

Description of Connascence of Identity is same as description of Connascence of Value. What is correct description.

Connascence of Identity occurs when multiple components must reference the same entity.

"characteristics" is misspelled "charateristics"

Figure 8-3 names left architecture style "layered architecture" and right "modular monolith".

In the following text they are called "Layered monolith" and "modular monolith". At this point (in chapter 8) is not (yet) clear, that a layered architecture implies a monolithic structure (as explained in ch 9).

Original:

Developers may have to **duplication** domain concepts in both common and local layers.

Fix:

Developers may have to **duplicate** domain concepts in both common and local layers.

Inconsistent naming of components, e.g.:

Video streamer (in figure)
VideoStreamer (in definition term [aka dt in HTML])
Video Streamer (in definition [aka dd in HTML])

These should probably unified into one format (CamelCase?).

"Most companies have multiple network hardware vendors in their infrastructure, if not more."
more than multiple ? I think it should be

I think contact should be contract.

However, notice that when the initiating event coming into the Simple Event Mediator is classified as either hard or complex, it forwards the original initiating event to the corresponding mediators (BPEL or BMP).
