This is in continuation to my first article around Microsoft TEAMS

Microsoft TEAM has been around for a while now and I think it’s time to discuss its architecture and feature in detail

To start with let’s understand the architecture of MS TEAMS

Service Architecture

NGC = Next-Generation Core (audio-video stack)

ECS = Experimentation & Configuration Service (a Skype configuration service)

MRU = Most recently used

WS = Windows service

WAC = Web App Companion

Teams MT = Teams Middle-Tier – used for auth, establish identity & region

Client Architecture:

How Authentication works in MS TEAM

Microsoft Teams uses existing O365 credentials to provide access

Identities are stored in Azure Active Directory

Aligns with existing O365 AAD authentication policies

Modern authentication: multi-factor authentication, smart card, and certificate-based authentication

As we all know, Every TEAM creates a SharePoint online Site collection (GROUP SITE) in the background but what gets saved in it.

· Each Channel in a Team gets a folder on this SharePoint Online site

· The Files tab uploads your collaboration files to this SharePoint Online site

· Files shared within a conversation are automatically added to the Files tab

· Permissions and file security options set in SharePoint are automatically reflected within Teams

· Files can be managed in the SharePoint web client by clicking the “…” next to the file name

TEAMS do have an option for private chat same as SKYPE for business, we can chat (Both Video and Audio) share our files, but where do those files get saved?

· All Private chat files are hosted in your OneDrive for Business

· Files shared in private chat are automatically shared in the sender's OneDrive

· Permissions are automatically granted to all participants in a private chat where a file is shared

· Clicking Files in the left rail gives you instant access to your OneDrive for Business files

Exchange got major role to play in MS TEAM

· Exchange Online creates a group mailbox and calendar for each newly-created Team

· Meetings created within Microsoft Teams are pushed to your Exchange calendar

· Meetings created in Exchange sync to the Meetings tab in Microsoft Teams

What are connectors and Bot in MS TEAM

· Office 365 Connectors also provide a way for developers to integrate with Microsoft Teams by building custom incoming web hooks Connectors to generate rich cards within channels.

· Bots are intelligent means to interact

Will MS TEAM fit in for compliance industry

· Industry standards: ISO 27001, ISO 27018, EUMC, SSAE16 SOC1 Type I & II, SOC2 Type I and II, HIPAA, FERPA, GLBA

· Protects team data using two-factor authentication, hard passwords, and access policies

· Data is always encrypted, whether chat, notes, or files

Lastly, what is 0365 GROUP has got to do inside Microsoft TEAMS

Microsoft Teams uses group membership as the access control list for Files and Notes tabs

How to migrate existing 0365 group to MS TEAM

1. Download the Teams desktop application here.

2. Open to the application.

3. Choose “Create Team”

MS TEAM has got more functionality and feature which we can’t cover in just 1 article, will add few more around BOT, TAB, and some admin and report functionality around MS Teams in my next subsequent articles.
