Build Apps Fast. Build Business Faster.

Multi-Tenancy Greatly Expands Enterprise Cloud Capabilities APIsSalesforce1 Mobile PlatformSales CloudService CloudCustomAppApp Exchange

Multi-tenant InfrastructureKey Takeaway: The multi-tenant of enables a growing range of key customer applications. This started with core CRM and has continued to expand to Service, Marketing and general Platform clouds

Talk started with CRM and expanded to Service automation, Marketing automation and now is a critical platform for App Exchange partners as well the best platform for customers custom appsThe focus of what we are going to talk about today is the underlying Multi-tenant infrastructure of Salesforce.comThis multi-tenant infrastructure ensures the high performance, availability and security of all of these applications

Multi-Tenant InfrastructureCore Tenets of InfrastructureApplication InnovationPerformance at ScaleAlways OnAvailabilityTrusted Security

Key Takeaway: There are 5 key focus areas for the Infrastructure leadership, Security, Availability, Performance, Application and Hardware (infrastructure)

Talk Track: There are 5 key areas that I would like to cover with you today, starting with Trusted Security, our Always on Availability, how well we perform at enterprise scale, our industry leading application innovation and finally how we scale the multi-tenant hardware infrastructureSalesforce Security Provides Multi-layer Zones of TrustAdaptive Flexible Security ModelInfrastructure-level SecurityApplication-level SecurityFirewallSSL AcceleratorsWeb/App ServersLoadBalancers

Database Servers

Trusted NetworksAuthentication OptionsField Level SecurityObject Level Security (CRUD)Audit Trail Object History Tracking

Key provides application level and infrastructure level security in different zones so that customers data is always protected

Talk Track:Salesforce has multiple layered zones of trust both within the application but also within the infrastructure. At the application level there are multiple different levels of access that can be granted starting with the ability to only login from trusted networks, all the way down to very specific field-level security access. And all of this is tracked. You can even set object level history tracking so you can see when individual changes are happening. Within the infrastructure the same is true for the various zones of trust. We have firewalls and access controls at every level of system and at the database layer to get direct access to the systems you have to go through a separate bastion host so direct login to the database servers is prevented. We also encrypt traffic that is flowing between our data centers so that we dont have data open as it travels between primary and backup locations. Another layer of security that we do within the data centers is that bad disks are erased 3 times and then shredded so data can not be recovered from these drives.

Overall site peak day>2 Billion transactions 200 milliseconds average 60% of transactions via API requestsTypically production instance>8,000 Customer Orgs30 App Servers and 8 DB ServersSalesforce.coms Daily PerformanceYesterday - ~2.5 Billion TransactionsKey Takeaway:

Talk Track:July 22nd was the first day that we delivered over 2 Billion transactions per day. Now we are delivering over 2.1B and during the work week averaging over 2B per day.

The infrastructure build out is continuing to enable strong customer transaction and data growth.

Salesforce has adaptive models and tools to manage software releases and ensure consistent high quality releasesWhats OnMulti Tenant Architecture

One Cloud with Many Customers

Environment = Tenant = Organization or OrgOne Primary Data Store per Production InstanceAll data segregated by customerAll operations include Org IDMulti Author12Metadata, data, and pivot table structures store data corresponding to virtual data structures

13A simplified look at some key metadata and data tablesNo DDL at runtime!Our flex schema uses clever de-normalization many patents pendingWe add data across tables for reporting (the big grid-like CFDATA tables)But we also have pivoted specialized tablesThe Objects table stores metadata about custom objects (tables)

14Naturally we have our own multi-tenant catalog tables like Oracles ownsystem catalog, but for our own bookkeeping

The definition of our custom objects is one of the most importantmetadata tablesThe Fields table stores metadata about custom fields (columns)

15And we have our own field catalog table our field types are richer thanstandard RDBMS types.

For instance multi-select picklists are stored in a special compact representationCustom Entity Data tableUnstructured at rest, cast to strong types when retrieved

16Massive, massive table wide and deep, billions of rows,partitioned, shared

All flex data stored in varchar columns canonicalforms for data types

ObjId distinguishes different tables for the same tenantThe same physical column is used for different purposesacross tenants and across objects within a tenant

Our query engine emits the proper SQL for all readersand writers of data (e.g. the Api and reporting)A single slot can store various types of data that originate from different objectsData IdOrg IdObject IdNameField0Field1a01dI000000qKJi00D01a01A0001Red20141024a01dI000000qKJj00D01a01A0002Blue20131023a02dl000000prNy00D01a02Fiat12000.00truea02dl000000prNz00D01a02Ford15000.00falsea01dl000000cKSr00D02a01Eiffel Tower DayParisa01dl000000cKSr00D02a01Historic Slough1 HourSlough17Example of a single column

Note that the underlying RDBMS cannot know about this usage.

Small conversion penalty for native data type processing
