Session Objectives And TakeawaysSession Objective(s): Learn mobile enterprise conceptsLearn how to build mobile middleware with SQL Server 2012 + IISLearn how to securely publish enterprise data out to the InternetLearn how to consume and work with data on Windows Phone 8 and Windows Tablets

Between 50% - 70% of your enterprise mobile app development takes place on the backend.Microsoft’s Mobile Enterprise Application Platform (MEAP) extends an organization’s backend systems out to mobile devices in a reusable way saving money and accelerating time to market.

Common core and security architecture

Great, consistent experience across devices

Productive and connected

Robust platform for mobile apps

Unified app and device management

Windows Phone is Built for Business

Mobile Enterprise Concepts

Why are Companies Going Mobile?Productivity and efficiencies are gained by letting employees work anytime from anywhereReal-time vs. batch-mode speeds up the cadence of decision-making to gain a competitive advantageTimely information allows employees to make better decisions at the point of activityExtending backend systems to mobile users is a top priority for CIOsData captured from the field is used in analytics

How does a Company Make this Happen?Mobile Middleware integrates multiple data sources, act as a server façade, & exposes composite data via Web Services in a format consumable by any deviceA Multi-channel Access Gateway securely publishes data out to the InternetDevelopment tools create server logic, client logic + UX, and integration with backend systemsDevices running apps and web browsers consume data and complete transactions in an offline state

Building Mobile Middleware with SQL Server 2012 + IIS

Mobile MiddlewareEnterprise application integration (EAI) with backend systems and data sourcesAggregate and cache composite data retrieved from those systemsCreate business entities that model the schema created by the aggregated dataBuild RESTful Web Services to expose business entities to mobile clients

Back End Systems + Data Sources via SSISPackagesSAP, Siebel, Oracle, Salesforce, Hyperion, Dynamics, SharePoint, Custom

DatabasesOracle, DB2, Teradata, Sybase, MySQL, Informix, PostgreSQL, Access, FoxPro, IngresVSAM, IMS, LDAP, Lotus Notes, ADABAS, ADO.NET, OLEDB, ODBC, SQL Server Compact

Visually Connecting AdaptersUse SQL Server Data Tools to Create SSIS PackagesCreate a Data Flow TaskCreate an OLE DB Source that points to a data sourcePerform needed data transformations along the wayCreate an OLE DB Destination that points to SQL Server

Encrypt SSIS Package and data via password or user key to secure integration data movementSSIS holds the world record for ETL operations at over 2 TB transferred per hour

Scaling Out SQL Server 2012Replication is a SQL Server database engine featureWhy allow all your devices to overwhelm a single database……when smaller groups of devices can connect to multiple, replicated copies of that same database

Databases, tables, and columns can be filtered and replicated to other SQL Server nodesDatabase shards are smaller and therefore faster because disk I/O is reduced since the ratio between memory and data on disk is improvedMost nodes download read-only database shards to accommodate SELECTs (READS)A small number of write-only nodes will be used to upload INSERTs, UPDATEs, and DELETEs (WRITES)

Geo-replication across data centers is facilitated by Peer to Peer Transactional ReplicationComplete copies of the database is replicated and kept up to date

Creating Web ServicesUse Multichannel Transports and Data FormatsREST is how the mobile Internet communicatesJSON is how the mobile Internet serializes data

Business Objects are modeled on database schemaRetrieve Data from SQL Server to hydrate your Business ObjectsSerialize collections of business objects as JSON

Performance + ScalabilityBoost performance and scalability with .NET MemoryCache or AppFabric Caching Increase scalability by load-balancing IIS servers

SSL + Basic authentication to secure data in transit

Getting Corpnet Data out to Devices

Securely Publish Data to the InternetUnified Access Gateway (UAG)Sits in the DMZ between front and back firewalls with inbound and outbound network interface cardsSecured with a certificate

Listens for web requests on external IP and routes internally to a single web site or load balancer (VIP)Specify a public DNS name “mobile.contoso.com” and a path “/” for the non-public virtual directory and folder of your web services or site

Securely Publish Data to the InternetTerminate and offload SSL traffic or pass it through to the web site via SSL bridgingPre-authenticate or allow web site to authenticateInspect both clear and encrypted packets for malware or other exploitsNO VPN REQUIRED because you’re publishing discreet services instead of exposing the entire networkYou already follow this model to publish Exchange email to devices
