What is TFS?

Team Foundation Server (commonlyabbreviated to TFS) is a Microsoft productwhich provides source code management(either via Team Foundation VersionControl, reporting, requirementsmanagement, project management (for agilesoftware development and waterfall teams,automated builds, and lab management,testing and release managementcapabilities. It covers the entireApplication Lifecycle Management TFS can beused as a back end to numerous integrateddevelopment environments but is designed toprovide the most benefit by serving as the

back end to Microsoft Visual Studio orEclipse (on Windows and non-Windowsplatforms).

Team Foundation Server is available in twodifferent forms, On-Premises and On-Line(hosted by Microsoft. The latter one iscalled Visual Studio Online.

Team Foundation Service is a subset of alarger suite that is called Visual StudioOnline. The cloud service offers the mostrecent features compared to the On Premisesversion of TFS (and uses the same code withminor modifications) backed by Microsoft’scloud platform, Windows Azure. For VisualStudio Online, there is no setup required,simply log in using Microsoft Account(previously called Windows Live Account)and develop. The main differences at thispoint between the cloud and on premisesversions of TFS involve customization andextensibility. For example, in the on-premises version, organizations cancustomize the process templates (see belowfor an explanation of process templates)

but in the cloud they cannot. The LabManagement capability can be plugged intothe on premises version but there is no labmanagement capability for the cloud. Last,two components are not present on theCloud-based version: SQL Reporting / BI andthe SharePoint.

On the other hand, the cloud does have somecapabilities, simply because of the natureof the cloud that the on premises versiondoes not have. These include anautomatically scalable build farm (onpremises teams have to configure many buildservers whereas in the cloud the buildservers are simply available) and virtuallyinfinitely scalable load testing (again,the on premises TFS requires that each andevery machine is configured for scalabilitytesting). And finally, new features come tothe cloud every three weeks because of therapid development cycle and these featurestake longer to migrate to the on premisesversion as updates (approximately every 3months).

By default, communication between thecomputers in a deployment of TeamFoundation uses the protocols and portsshown in the following table. If anasterisk (*) follows the port number, youcan customize that port.

Which module it has?

Team Foundation Server architecture

To best plan and manage your deployment,you should first understand the underlyingarchitecture of Team Foundation Server(TFS). Understanding the architecture canhelp you maintain the overall health of thedeployment and help ensure the overallavailability of the servers and servicesyour development teams require.

You can deploy TFS in several ways: on oneserver; on many servers; or in one domainor workgroup or across domains.Alternatively, you might choose to useVisual Studio Online, where all the serverelements of your deployment are hosted foryou by Microsoft. Understanding thearchitecture can help you decide what

true

topology is most likely to meet yourbusiness needs. Regardless of your choiceof topology, if you understand thearchitecture underlying TFS, you can bettermanage the physical and logicalrequirements. This topic provides a simpleoverview of the various architectures, withlinks to more information about exampledeployments. It also provides technicalinformation about the services, databases,configuration information, and networkports and protocols of local deployments

Visual studio online

Microsoft offers the option of using VisualStudio Online, where all of the server-sideaspects of the deployment are hosted foryou. Your source code, work items, buildconfigurations, and team features are all

hosted in the cloud. From an architecturalpoint of view, this greatly simplifies yourdeployment, as the only aspects of thearchitecture you need to consider are theclient components and their Internetaccess.

When using the service, you use a webbrowser to connect to the service usingyour Microsoft account. You can create teamprojects, add members to your team, andwork as you would with a locally installeddeployment, without the overhead ofadministering the servers. Your applicationtier, data tier, and build servers arehosted for you in the cloud, using theMicrosoft Cloud platform and SQL ServerAzure

Object model:

With either the hosted or the locally-deployed architecture, you can extend thefeatures and functionality of TeamFoundation by writing an application thatis based on its server or client objectmodel. In all deployment types, you can

write applications that extend clientcapabilities. However, if you want toextend server capabilities, yourapplication must run on the application-tier server. To extend the clientcapabilities, you must run the applicationon the same computer as Team Explorer.

.

Similarly, the hosted service for TFS isconfigured to use specific network portsand protocols. The following illustration

shows network traffic in a hosteddeployment.

.

Collection-level service

Collection-level services provide thefunctionality for operations at the levelof the team project collection. You cancreate applications that extend TeamFoundation Server by using some of theseservices. For more information aboutcreating applications for TFS, seeExtending Team Foundation

TipSome services appear in more than onelevel. For example, the Registry servicefunctions at the collection level and theserver level, and appear in both lists.

The data tier includes data, storedprocedures, and other associated logic.When you use Visual Studio Online, the datatier is hosted for you using SQL ServerAzure. In a local deployment of TFS, thelogical data tier consists of the followingoperational stores within SQL Server. Thesestores might be located on one physicalserver or distributed across many servers.You can create applications that extendTeam Foundation Server by using some ofthese operational stores. For moreinformation, see Extending Team Foundation.

Databases for teamproject collections(TFS_CollectionName)

The following table provides a list of thedatabases that Team Foundation Server usesin local deployments. Unless otherwisenoted, you can move all databases in thislist from the original server and instancewhere they are installed and restore themto another server or instance.

Network ports and protocol

By default, a local deployment of TFS isconfigured to use specific network portsand protocols. The following illustration

shows network traffic for Team FoundationServer in a simple deployment.

Similarly, the hosted service for TFS isconfigured to use specific network portsand protocols. The following illustrationshows network traffic in a hosteddeployment.

The following illustration shows networktraffic in a more complex deployment thatincludes the components for Visual StudioLab Management.

How the features of ALM are implemented inTFS?You can use Visual Studio ApplicationLifecycle Management (ALM) to manage yourproduct lifecycle, reduce risks, andimprove efficiencies. When you install orupgrade to Visual Studio Team FoundationServer 2013, you and your team can benefitfrom the new features and supported tasksoutlined in the following table.
