About Salesforce1
3
Salesforce.com offers "Salesforce1" an extremely powerful, scalable and secure cloud computing platform to develop, package and instantaneously deploy applications without any in-house infrastructure.
The hosting structure is a shared multi-tenant architecture, in which all users and applications share a single, common infrastructure and code base that is centrally maintained.
Because there are no servers or software to buy or manage, focus is solely on building apps that include built-in social and mobile functionality, business processes, reporting, and search.
The apps run on a secure, proven service that scales, tunes, and backs up data automatically!
About Salesforce1
4
PROVEN
•More than 100,000+ companies trust Salesforce1, including many industry leaders. They’ve built 220,000+ apps that run in accredited, world-class data centers with backup, failover, disaster-recovery, and an uptime record exceeding 99.9%.
AGILE
•Salesforce1 requires minimal coding. Assemble the apps in building-block fashion using visual tools and library of components. Streamline development with sandbox environments, and integrate the apps using open APIs.
SOCIAL
•Work more effectively with colleagues using own secure social network. Salesforce1 includes pre-built components for feeds, profiles, conversations, updates, and file sharing. All components are available through REST APIs that can be easily integrated into any custom app.
MOBILE
•Build native mobile apps powered by a secure cloud database, with rock-solid APIs. Or build mobile-optimized browser apps, using our UI framework and HTML5 to support any device with one code base. Or mix native and HTML in a hybrid cocktail that gives the best of both worlds.

Physical Architecture
8
Customer traffic starts with external DNS. Once a lookup has successfully returned the IP address for an instance, standard Internet routing directs it to the appropriate datacenter.
Once the traffic enters Salesforce network in that datacenter, it is directed to the load balancer pair on which that IP lives.
The load balancer directs the traffic to the application tier of the given instance. At this tier, both standard web page traffic as well as API traffic are serviced.
Depending on the needs of the customer's request, it will be directed to additional server tiers for various types of backend processing.
This is what happens when logged in via login.salesforce.com:
Physical Architecture
9
The core app tier contains anywhere from ten to 40 app servers, depending on the instance.
The batch server is responsible for running scheduled, automated processes on the database tier.
Core App The primary data flow occurs
between the core app server tier and the database tier.
Each primary instance (e.g. NA, AP or EU instances) uses an 8 node clustered database tier.
Data base
Search tier runs on commodity Linux hosts with both active / passive nodes.
Search indexes are stored on the flash drive to enable greater performance for search throughput.
Search FileForce is a tier of servers that provide object storage, similar in concept to Amazon's S3.
This system is designed to reduce the load on Database tier.

Logical Architecture

Multi-tenancy
Multi-tenancy is a new architecture that makes it
possible for all applications from all organizations to run
on common physical infrastructure.
Salesforce1 uses a runtime engine that materializes all
application data from metadata — data about the data
itself.
11
There is a clear separation of the compiled runtime
database engine (kernel), tenant data, and the metadata
that describes each application.
These distinct boundaries make it possible to
independently update the system kernel and tenant-
specific applications and schemas, with virtually no risk
of one affecting the others.
Each tenant application is composed at runtime from rich
metadata via shared runtime engine (kernel).

FAQ - Data
18
FAQ Answers
Are there any Import/Export
processes for data?
Salesforce provides the following options for importing / exporting of data:
Data Loader: Provided by Salesforce to import / export the data from
Salesforce using csv file.
Apex programming / API: For loading the data / extracting the data which
has got complex related data (where in multiple tables are involved), then
batch programs could be written to read from the file and load into
Salesforce or export the data out of Salesforce in an XL.
Import Wizard: Using this the data can be loaded quickly but the limitation is
that the data can be loaded into a single table (object) every time.
Workbench: This can be used to write SOQL (Sales object Query
Language) to export the data in XL.
Prerequisite to use the Data Loader:

FAQ – Network
19
FAQ Answers
Are there any Bandwidth
(client/Server) considerations?
Salesforce.com is designed to use as little bandwidth as possible, so that the
site performs adequately over high-speed, dial-up, and wireless Internet
connections.
While average page size is on the order of 90KB, Salesforce.com supports
compression as defined in the HTTP 1.1 standard to compress the HTML
content before it is transmitted as data across the Internet to a user's
computer. The compression often reduces the amount of transmitted data to
as little as 10KB per page, viewed due to the lack of image content.
It is difficult to specify customer bandwidth because of the nature of the
Internet and individual corporate usage. Network latency, peering issues,
bandwidth at upstream providers, users using their Internet connections for
other use besides Salesforce.com, etc. all affect the perceived performance of
the connection and the amount of bandwidth required to keep performance
adequate.
Salesforce.com recommends engaging a networking professional to help
measure, allocate, and monitor appropriate bandwidth and networking
resources.
Is there any Latency when
connecting to your application?
It is purely based on the nature of the Internet and individual corporate usage
of network bandwidth.
How could the actions of other
cloud customers or their cloud
users impact on the quality of
service of the cloud provider?
Architecture plan, custom code reviews plus certain governing rules like API
governors in place (limits to the number of API calls by each customer over a
defined time period) to ensure service quality.

FAQ – Backup & DR
21
FAQ Answers
Please describe the Backup &
Recovery plan
Disaster Recovery
All customer data is stored in secure data centers and is replicated over
secure links to a disaster recovery data center. This design provides the ability
to rapidly restore the salesforce.com service in the case of a catastrophic loss.
Backups
In addition to our disaster-recovery capabilities, customer data is also backed
up to tape in a separate data center. Tapes are not transported offsite from this
data center, reducing the risk of loss.
