Design a SharePoint 2013 Architecture – The basicsDecember 2013Alexander Meijers
“A SharePoint architecture is a blueprint of a SharePoint platform which incorporates all related aspects which influence the platform in some way.”
So what is an architecture?
Architecture depends on many things Structure of content and data Accessibility of content and data Availability (content, data, services) Scalability Infrastructure (offline / online / hybrid) LOB / External systems Services & processes
So architecture is not only a bunch of servers!!!
Architecture or what?
How to create an
architecture
Content & data What kind of? What is the purpose?
Accessibility Which groups of people can you identify? How is access handled?
Infrastructure Where is everything stored? On-premises, online or Hybrid?
Architecture What is needed? Which services are used? Any external (LOB) systems?
Stakeholders Who is involved during the design? Without them your design will not be accepted!

Explain the steps
in creating an
architecture
What kind of SharePoint platform Publishing Portal Intranet environment Collaboration sites Dashboard of data Data storage (e.g. Knowledge Center) Search driven environment Combination of above
Legacy Is it a migration? New platform next to an existing one Expanding an existing platform
Content & data
Availability My Sites less available than intranet Publishing site on internet highly
available
Amount of content Current amount of content Expected growth Backups
Usage of custom components
Is there any custom development? Are they going to use SharePoint Apps?
Content & data External Systems Is data exposed from external (LOB)
systems? Are there forms used which post
data to external systems?
Keep track of your boundaries
Maximum size of content databases Number of web applications and
site collections Number of application pools
Who is accessing which data and from where?
Define groups of people
What kind of data is accessed?
Accessibility
Groups of people Location Data Accessed
Internal employees Intranet Intranet Portal, Company information, internal data, internal project sites, my sites and profiles.
External employees Internet, Remote Session
Same as internal employees
Partners Internet, Remote Session
Project sites, Partner Portal
Visitors Internet A companies website, customer Portal
How is data accessed by these groups of people?
Content is offered through Farms Web applications & Zones Site collections
Content is accessed through NTLM through Active Directory Form Based Authentication Claims-based authentication Third-party authentication method Key or SMS service Combination of above
Accessibility
Get the numbers of users and their activity
Number of users Current users Expected growth
Usage Expected usage of the platform (e.g. number of simultaneous users) Peak moments (bursts of users)
Accessibility
There are many choices when it comes to infrastructure. So what do you choose?

Virtualization VMWare Hyper-V

Topologies
Standard topology The standard three-tier topology in which the farm is divided into three layers.
Streamlined topology A topology to optimize system resources and to maximize performance for users. Optimize for Low latency, Load and Throughput
Other options Mobile Architecture Global solutions Hybrid topologies

Topologies - Server RolesRole Traditional Topology Streamlined
Topology(each tier optimized)
Streamlined Topology(Optimize for)
Web Server Fast, Light-weight server which responds to user requests from web pages. All web servers are mirrors of each other and load balanced. Directs requests to the appropriate application servers
Service Applications, Services and components that serve user requests directly
Low latency
Access Services, BCS, Metadata, User Profile
Application Server
Runs one or more services in the SharePoint Farm. Load balancing possible by redundant application servers
Service Applications, Services and components that process background tasks. Also called batch processing.
Load
User Profile Synchronization, Workflow, Machine translation, Work management
Search on separate dedicated machines
Database Server
Stores content and service data. Databases can be clustered or mirrored for failover protection

Topologies – Farm typesFarm Number of
serversPurpose
Limited Deployment 1-2 Used for product evaluation, development and testing with a limited number of users
Small farm 3-4 Serve a large number of users and scales out based on how heavily services are used. These types of farms are not always fault-tolerant
Medium farm 6+ Serve a large number of users and scales out based on how heavily services are used. Their goal is a multi-purpose environment with possible optimalisation. These farms are always fault-tolerant.
Large farm Mostly a lot Serve a large number of users. Group service applications, services or databases that have similar performance characteristics on dedicated servers
Start designing your
SharePoint 2013
architecture
Use the gathered information on content & data, accessibility and infrastructure
Use the technical diagrams for SharePoint 2013 as a starting point
http://technet.microsoft.com/en-us/library/cc263199.aspx They contain different approaches (choose wisely ) Great resource for designing your architecture

Web Servers In a multiple server farm each web
server represents 10000 users Using multiple front-end web servers
allows you to divide load
Services Move services which use too much
resources to separate Application Servers Search Service mostly needs a separate
Application Server Run services on multiple Application
Servers for redundancy Let the Search crawler crawl the
application server in stead of the web server
Architecture – Some takeaways Databases A small Farm environment can host
all databases on a single server Group databases based on their role
on multiple servers for larger environments
Servers Less virtual servers are needed
when using Windows Server 2012 in stead of Windows Server 2008 R2 due to the fact that a larger of resources can be allocated for the virtual machine
