Why Hybrid SharePoint?

11. The
Evolution
of
SharePoint:

| Server | Server
HYBRID
Team
Sites
Portals
Enterprise
Content Mngt
BI

12. Approaches to Hybrid SharePoint
Split Workload
different tools in
different places
Split User
task uses content or
sites across ‘the divide’
Exchange, SharePoint, Skype
OneDrive, Yammer, PowerBI, Delve
Extranet, Mysites, Team Sites, Project Sites
Portals, Intranet, Services/Applications
Links Search

13. Search Provides a Unified View

14. “Classic” Hybrid Search is Federated
not a single result set OOB

0-10 million items small 4 App + 2 DB 1 or 2
10-40 million items medium 12 App + 2 DB 2
40-100 million items large 28 App + 4 DB 2
400 million items XL example (SP2016) 86 App + 4DB 2 or 3

20. Benefits of Cloud Hybrid Search
2) Makes finding content easy, wherever the content lives
1) Simpler, easier, and less costly to run search

24. The Cloud SSA

26. Result Sources are Your Friend
SharePoint Online
Custom result source using Local SharePoint results plus
a filter which excludes results from on-premises
TIP: Can be used during validation of hybrid search in
the production tenant.
Result source query:
{searchTerms}
NOT(IsExternalContent:1)

27. Start with “Everything”?
This is the default result source using Local
SharePoint results but it has been renamed to
«Everything» in the Search Navigation
configuration.
SharePoint Online Everything

28. Result Sources are your friend
The Support Search vertical only searches sites that
are relevant to the Support team.
It uses Local SharePoint results plus a filter on
which sites to include in the search results
Result source query:
{searchTerms} (
Path:»http://sp2010» OR
Path:»file://fileshare» OR
Path:»http://demohybrid...
/../supportforum»)

- on-premises and on-line
- inside and outside SharePoint

36. Current Caveats:
1) don’t see thumbnails, just file icons
2) Have to query for it to show up

38. Scaling

39. Item Limits and Pricing
Licensing: 1M items of external content in index for every 1TB storage in O365
1TB included by default
+ 0.5 GB per licensed O365 user
No limit on number of items from O365 in the index
Default throttling at 20M external items; current threshold at 25M
2000 users x 0.5 GB = 1TB
+ 1TB default = 2 TB total
-> 2M external items indexed
+ Can also buy the “Office 365 Extra File Storage” Add-on
$0.20/GB/Month = $200/TB/Month = $200/M items/Month
50,000 users x 0.5 GB = 25TB
+ 1TB default = 26 TB total
-> 26M external items indexed

44. SUPPORTED
– Custom IFilter
– BCS connectors
– Partner connectors
Customizations with Cloud Hybrid Search
SUPPORTED
– Tenant level schema mapping
– Query rules
– Result sources
Cloud SSA SCS/O365
NOT SUPPORTED
• Content that requires custom
security trimming
NOT SUPPORTED
• Site collection level schema mapping
• Custom security trimming
• Custom entity extraction
• Content enrichment web service

45. Issues with Cloud Hybrid Search (1)
Cloud Hybrid Search "annoyances"
Performance Characteristics
slower query latency for on-prem queries against Cloud SSA
SharePoint Online Limitations
no synonyms
no site-level schema
no full trust code access
Hybrid Administration Weaknesses
clunky metadata mapping
can't remove on-premises search results from Cloud SSA
trickier to test & debug crawls
can't reset index from Cloud SSA
Be aware of these
& compensate for them
(Fixed in August PU)
(Semi-addressed in June PU)
And it’s getting better:

46. Should I run index reset?
NO!

61. Key Considerations for Hybrid:
Workloads, Environment, Data, Customizations
Availability of features Online versus
On-Premises on particular workloads
Significant investments in
customization of On-Premises
workloads
Concerns over global network
performance with remote sites
Regulatory
considerations
Manageability concerns
