Service Instantiation
=====================
**Pre-requisites**
- The Service has been designed and distributed (see: :ref:`Service Design <doc_guide_user_des_ser-des>`)
- pre-instantiation operations have been performed
(see: :ref:`pre instantiation section <doc_guide_user_pre_ser-inst>`)
**Possible Tools to perform Service Instantiation**
- **via a Graphical User Interface tool**
using ONAP applications such as **ONAP VID** and **ONAP UUI** tools
- **via any tool able to perform REST API requests**
(for example : Robot Framework, Postman, Curl...) connected
to **ONAP SO** legacy API or **ONAP extAPI/NBI** standard TMF641 API
to add/delete Service.
**Possible methods with ONAP to instantiate a Service**
- **A La Carte**
method requires the user to build and send
operations **for each object** to instantiate : Service, VNFs,
VFModules and Networks (in other words : once you have instantiated
the Service object, you still have to instantiate the various VNFs
or Networks that compose your Service).
To build those requests, the user needs to define/collect by himself
all necessary parameters/values.
- **Macro**
method allows the user to build and send
**only one request to instantiate all objects** : Service, VNFs,
VFModules and Networks. Thanks to templates (see CDS Blueprint in
Design section),
ONAP will collect and assign all required parameters/values by itself.
.. Note::
VID supports the "macro" flow orchestration in a ModernUI, which can be enabled by the system operator.
**Macro** method is not (yet) available via extAPI/NBI.
