Every cloud implementation of D365 Finance and operations
offers three types of environments.
Tier-1 environment: Tier 1
environments include Develop and test boxes. As a standard MS provides one
develop/test instance for the duration of the subscription. This instance is a
non-production single-box instance and can be used for Development OR Unit
testing OR an automated build environments. Customer can purchase additional
develop/test instances separately as an optional add-on. Provisioning for
Tier-1 occurs When the Design phase starts. The provisioning process requires
that Microsoft Azure DevOps be configured.
Tier-2 environment: Tier 2
environments includes a Standard Acceptance Testing (SAT) Or User acceptance
testing (UAT). As subscription plan One Standard Acceptance Testing (UAT)
instance is provided for the duration of the subscription. This instance is a
non-production multi-box instance which
can be use for UAT, integration testing, and training. Customer can
purchase additional sandbox/staging instances separately as an optional add-on.
Provisioning for Tier-2 occurs During on-boarding with the Microsoft FastTrack
team.
Production environment– One
production instance is provided per tenant. The production multi-box instance
includes disaster recovery and high availability. It will be provisioned when
the implementation approaches the operate phase, after the required activities
in the LCS methodology and a successful go-live assessment are completed. There
is no option to buy another environment this category. Provisioning for
production environments occurs at the time of production system readiness
phase. A production deployment request must be submitted in LCS. Deployment is
done through the Dynamics Service Engineering (DSE) team within two business
days.
Additionally, the following file storage and database storage
are included:
File storage - Every customer receives 100 GB
of file/Azure blob cloud storage for files and binary data. Additional
file/blob storage can be purchased.
Database storage - Every Finance and
Operations apps subscription includes 10 GB of Azure SQL Database storage per
customer at no additional charge. Additional storage capacity is provided at no
charge as an organization increases the number of user and device service
licenses.

All components are
installed on the same server, a Virtual Machine. These components include
Application Object Server (AOS), the database, Dynamics 365 Retail, and
Management Reporter. These components include Application Object Server
(AOS), the database, Dynamics 365 Retail, and Management Reporter.

Components are
installed on multiple cloud services, and typically include more than one
Application Object Server (AOS).

Microsoft SQL
Server is used.

Azure SQL
Database is used.
|
The architecture
differs from the architecture of the production environment to maximize
efficiency and cost of the development team.
|
The architecture is
the same as the architecture of the production environment, even though this
type of environment has a different sizing and isn't enabled for disaster
recovery.
|
The environment can
be deployed in various ways. For example, it can be deployed as an add-on, it
can be cloud-hosted, or it can be deployed as an environment image (VHD).
|
The environment can
be deployed only as a standard environment or an add-on environment. It can't
be cloud-hosted.
|
The environment
isn't suitable for UAT or performance testing.
