 # Architecture
 
+The CAPIF architecture has three main components, Register Service, Vault and CCF, which are represented in the following image:
 
+![New Architecture](./images/architecture/New_Architecture.png)
+
+Each component is separated into different namespaces and all communications between them use Rest APIs.
+
+Apart from the communication between components, there are 2 other entities that can use them:
+
+- Admin/superadmin: Responsible for managing users with the Register or carrying out special operations in the CCF.
+- Users: They are those who want to use CAPIF, registering as a user in the Register and as Invoker or Provider in the CCF.
+
+## Register NS
+
+This namespace belongs to the Register service, and we find 2 components:
+
+- Register Service: It is responsible for managing all users who use CAPIF, in addition to providing the necessary information for its use.
+- Register MONGO DATABASE: It is the Register database, in it we store all the information about registered users.
+
+## Vault NS
+
+This namespace belongs to Vault. 
+
+This component is responsible for managing all CAPIF certificates, so other components such as the Register or the CCF communicate with it to create new certificates or request keys.
+
+## Mon NS
+
+This is the main namespace of CAPIF, since it contains all the CCF services in addition to other components:
+
+- NGINX: Responsible for acting as a reverse proxy to distribute CAPIF requests to the different services, controlling whether or not they are authorized to access them.
+- REDIS: Used for internal communication of services.
+- CAPIF MONGO DATABASE: CAPIF database, where all information related to CAPIF services such as invokers, registered providers or published services is stored.
+- HELPER: Service that simplifies integration with third parties such as external management portals.
