Azure Powershell from VS Code

Overview:  I am moving over to using Visual Studio code for everything including PowerShell.  Historically, I would use PowerGUI as it was the best IDE for PS for many years but PS ISE is excellent and I don't see a material difference these days.  Basically, I use VS code for my ISE for JS, SPFx, C# unless the full versions of Visual Studio speed up my delivery rate, this allows me to remain in VS code without going to PowerGUI or 1 of the Windows PS consoles/IDE.

Get the VS code debugger working: 

Get the IDE (VS Code) ready
On a new VS Code install, add the VS Extension "PowerShell", the VSIX has the description "Develop PowerShell scripts in Visual Studio Code!"



Run and Verify PS is working and output returned is working

Add the Azure Account Extension
Sign into Azure
A notification pops up to authenticate the machine/laptop with you Miscrofot credentials.  Run the popup and sign in to authenticate the local dev IDE.

 Open the Cloud Shell
Verify you are signed in

Geo-replication in SharePoint and SPO to the recue

Geo-Replication on SharePoint (Not covering email or OneDrive)

Problem: Over the past 7 years, I have worked on a few clients that require some form of Geo-Replication of share SharePoint farms.  Geo-replication is normally needed for compliance.  This post assumes you need to geo-replicate and not why you need to geo-replicate

Tip: Geo-replication can be used for performance but the complexity that it brings I feel is an added bonus and should not be undertaken for performance gains, there are easier better pragmatic answers to performance such as Riverbed devices, caching and CDN's to name a few.

Initial Hypothesis:  Large organisations existing in multiple geographic regions and need to abide by country regulations and often other industry standards bring the need to geo-replication capability.  I recently completed several high profile projects for a big four consultancy that needed to ensure SharePoint data does not leave its jurisdiction depending on its metadata.  Building on-prem Sharepoint farms were extremely complex and the 3 big services that needed to be centralised or copied are Search, MMS and the Content Type Hub.  There are more like AAD but for my situation, I needed to be able to have multiple SharePoint farms in specific regions that connected to centralised services.

Thoughts: MS has OneDrive and the email piece working in local geographies.
SharePoint is coming with multi-tenancy and users will get unified search results across geographic regions.
  1. Search each tenant holds their own index, not a central index for search - "good news for data location compliance".  Somehow MS are intermingling all the search results using federation - wow.  
  2. Profile Services (use to be UPS) gets core fields from central AAD and local fields are stored at a tenancy level (good news).  
  3. Taxonomy (MMS) is replicated downwards from the central MMS.
  4. Each tenant has it's own content type hub (I never liked this), the CTH uses a star topology to push the CTHub from the central tenant to the regional tenants so the copies including GUIDs are identical.
SPO to the Geo-Rescue (coming soon, in pre-beta as of 6 June 2018):
  • SPO is implementing multiple tenants across O365 like O365 previously did for OneDrive, you can specify where sites get created i.e. region/country.  Each region as it's data centres specified and the URL of the Sites clearly indicates where the site is hosted.
  • The search index is kept in-country and federated up to the central tenant for a seamless search experience across multiple region tenants.
  • Central taxonomy is automatically replicated to the regional tenant.  MMS us a star topology to distribute and keeps GUIDs in sync.
  • UPA holds only key data centrally and each region holds additional properties (good for GDPR and other DPA regulations).
  • AAD is controlled centrally and I believe AAD's have regional copies.
RoadMap:
OneDrive is multi-geo now.  > Circa Oct-Dec 2018 SharePoint will offer multi-geo (yeah).
