This text:
1. At the top sit the modern applications, which can be exposed directly via the API gateway. In this pattern the application uses modern communication, such as REST/JSON.
2. In the middle are the legacy applications, which require additional decoupling via the ESB. The service of the ESB can be wrapped into the API gateway.
3. At the bottom sits microservices communication. Microservices communicate internally via the service mesh. APIs, which need to be exposed externally, are decoupled via the API gateway.
Doesn't correspond to the picture. Must be changed into:
1. At the bottom left are the legacy applications, which require additional decoupling via the ESB. The service of the ESB can be wrapped into the API gateway.
2. In the middle sit the modern applications, which can be exposed directly via the API gateway. In this pattern the application uses modern communication, such as REST/JSON.
3. At the right sits microservices communication. Microservices communicate internally via the service mesh. APIs, which need to be exposed externally, are decoupled via the API gateway.

Broker / mediators topologies |
Hi.
You state that publish/subscribe is a software architecture implementation of the mediator topology.
Then you go on to state: "Unlike the mediator topology, the broker topology model can also be used to implement the publish-subscribe model."
This is confusing and seems to be a contradiction. Please clarify.
Overall, a great book which I greatly enjoy reading.
Best
Oliver
Note from the Author or Editor:
The word "Unlike" should be changed to "Just like". So this sentence:
Unlike the mediator topology, the broker topology model can also be used to implement the publish-subscribe model.
Should be replaced by:
Just like the mediator topology, the broker topology model can also be used to implement the publish-subscribe model. |

1st paragraph |
Book reads: A practical way to begin implementing MDM into your organization is to start with the simplest implementation style: repository
Repository is not one of the four styles mentioned in the chapter.
Note from the Author or Editor:
A practical way to begin implementing MDM into your organization is to start with the simplest implementation style: repository.
Repository here must be changed to registry. |
