Pivotal Application Service (PAS) for Windows
Pivotal Application Service for Windows (PASW) enables PCF to host full .NET Framework and Windows-based applications, using Windows Server 2016 and its native containerization features.
By deploying the PAS for Windows tile in the Ops Manager Installation Dashboard, operators can provision, operate, and manage Diego cells based on Windows Server 2016. Once deployed, developers can then push .NET Framework applications to Windows Diego cells using the Cloud Foundry Command Line Interface (cf CLI) and specifying the
Operators can install PAS for Windows on Microsoft Azure, VMware vSphere, or Google Cloud Platform (GCP). See the note below regarding support for Amazon Web Services.
For more information about how PAS for Windows works, see the Product Architecture topic.
For the PAS for Windows release notes, see the Release Notes topic.
To install the PAS for Windows tile, you must have the following:
Any patch version of Ops Manager v2.1, deployed to vSphere, Amazon Web Services (AWS), Google Cloud Platform (GCP), or Microsoft Azure.
Any patch version of Pivotal Application Service (PAS) v2.1.
A Windows Server 2016 (v1709) stemcell, which you can obtain by following the directions in Downloading or Creating Windows Stemcells. Note that PAS for Windows uses Windows Server 2016, Server Core, version 1709.
The minimum recommended resource requirements for each Windows cell are as follows:
- Disk size: 64 GB
- Memory: 16 GB
- Number of CPUs: 4
Due to Microsoft’s licensing requirements, operators must bring their own licensed copies of Windows Server for on-premise deployments (vSphere) or, for public IaaS deployments, pay the surcharges associated with Windows Server licensing determined by the public IaaS provider on Microsoft Azure, Amazon Web Services, and Google Cloud Platform.
As of PCF v2.1, PAS for Windows is a new product offering that uses a new base OS version for its required stemcell. Thus, there is no direct upgrade path from PAS for Windows 2012R2. To upgrade with no downtime for applications, operators must install both PAS for Windows v2.1 and PAS for Windows 2012R2 v2.1 and use a blue/green deployment to achieve a zero-downtime upgrade for applications. See Migrating Apps to PAS for Windows for details.
PAS for Windows has the following limitations:
- Developers cannot yet push Docker or other OCI-compatible images to Windows 2016 cells.
- Container-to-container networking is not yet available for Windows-hosted applications.
- Volume Services are not yet available for Windows-hosted applications.
- OpenStack is currently not supported for PASW. Contact your Pivotal representative for information on OpenStack deployments.
Currently, AWS does not provide the version of Windows Server required by PAS for Windows, Windows Server version 1709. Contact your AWS representative for information regarding the availability of this OS version.
The following Windows technologies are not supported by PAS for Windows 2012R2:
- Active Directory Domain Services, i.e. joining Windows cells to an Active Directory domain.
- Integrated Windows Authentication. Instead, operators should deploy Active Directory Federation Services and the Pivotal SSO tile to enable OAuth-based authentication.
These limitations will be addressed in subsequent versions of the product.
PAS for Windows has the following known issues:
In the PAS for Windows tile Credentials tab, the
vcapcredentials that appear when you click VM Credentials > Link to Credential do not apply to Windows cells, since they do not yet have a vcap user on the Windows host. To establish access for an
Administratoruser, please see the VM Options tab to specify a password for that user.
The controls in the Advanced Features pane have no effect.
In the Resource Config pane, setting VM disk size has limitations detailed in the Configure Tile Resources table.
