The Application Development Landscape - 2011

APPLICATIONDEVELOPMENT - 2011A World of Change

Broad Macro Changes• Mobile • Consumerization of IT• Social • HTML5• Local • Component reuse• Cloud • Open Source• PaaS • Security challenges• Big Data • Agile SCRUM

The Dawn of the Post-PC Era Thanks to Mary Meeker and Matt Murphy

Mobile Internet - 10x bigger Thanks to Mary Meeker and Matt Murphy

Mobile Computing changes• Always with you. Always on. Always connected.• Social: Leverage Facebook, Twitter, etc.• Local: GPS = amazing new apps• New Device capabilities • Touch interaction • Camera & Camcorder • Voice input • Gyro + Accelerometer• Easy Integration with key apps • Maps, Phone, Contacts, Calendar, SMS messaging, etc.

Mobile + Cloud = Exceptional Power• Access pretty much anything • Maps, music, photos, social, etc.• Apps can be made far more powerful • Social connections • Big data • Huge compute power• The cloud becomes your single storage point for stuff • Documents, music, photos, etc.

Leads to a Wave of Innovation Unmet Need New Technology Entertainment Just passed 1 Million Mobile Apps (Doubled in the last year)

Cross Platform Development Smartphone & Tablet screen size

HTML5 versus Native Apps Or Hybrid to get at Device Functionality such as Camera, GPS…

AppStores• New distribution model• Built in Billing and in-app commerce • Open up new opportunities: Free to Paid

CLOUD COMPUTINGA Major Revolution

Three Flavors of Cloud SaaS Software (Applications) PaaS Platform IaaS Infrastructure (e.g. Amazon Web Services)

Before PaaS Unit Test Functional Test Source Jenkins Code Continuous Load Managemnt Integration TestDeveloper IT • “Please provision the following servers” Integration • “Please install the following software” Test • “Please maintain and update the software” • “Please create copies of my test databases” • Etc.

With PaaS: Automated Provisioning Unit Test Functional Test Source Jenkins Code Continuous Load Managemnt Integration TestDeveloper PaaS Portal • “Please provision the following servers” Integration • “Please install the following software” Test • “Please maintain and update the software” • “Please create copies of my test databases”

PaaS • No Waiting • No Errors

PaaS: Continuous Integration Integrate, Build & Test

PaaS: Continuous Integration Fail!

Continuous Integration Unit Test Functional Test Source Jenkins Code Continuous Load Management Integration Test Integration Test

Test Workload: very spikey Perfect for the public cloud

DevOpsDevelopment Operations • • ? “What’s the configuration?” “Wait while I get that set up” • “That didn’t work. Are you sure you gave me the right config?”

Continuous Deployment PaaS Automatically configures each environmentDevelopment Staging Production

Other Benefits of PaaS• Automatic Scale-out • New machines added and removed to handle varying load• Fault tolerant: Session-level Failover • Customer sessions/transactions are not lost when servers fail • Not in all PaaS offerings

PaaS Focus on the App, not the Plumbing PaaS becomes the new Operating System for Applications

PaaS Focus on the App, not the Plumbing Impact: Much Faster Time-to-Market

How Enterprises move to the Cloud SaaS Private Cloud (IaaS & PaaS)Private Cloud• Secure• Easy access to DataDrawbacks• Expensive to Manage• Not flexible

Hybrid Cloud SaaS Private Public Cloud Cloud (IaaS & PaaS) (IaaS & PaaS)

SAAS DEVELOPMENT

SaaS versus Licensed Licensed Software Software as a Service• 9-18 months for a new version • New version every month• Support multiple old versions • Only one version to support• Hard to get usage feedback • Instant feedback on usage• Expensive to ship bug fixes • Fix bugs instantly

SaaS versus Licensed Licensed Software Software as a Service• 9-18 months for a new version • New version every month• Support multiple old versions • Only one version to support• Hard to get usage feedback • Instant feedback on usage A Major Transition underway• Expensive to ship bug fixes • Fix bugs instantly

SaaS: New Challenges• Multi-tenancy• Usage tracking, Billing• Big Data• Scaling and Fault Tolerance• Etc. Note: PaaS can help solve many of the above

BIG DATA

Big Data: Structured NoSQL NewSQL CassandraMySQL MongoDB Sharded Etc. MySQL

Big Data: Unstructured

Silo Problem Structured Unstructured SQL NoSQL NewSQL

Analytics• What happened?• What is likely to happen going forward?

Problem: • Limited SQL • Extremely Slow • Incompatible with today’s BI tools

Analytics “Give Me Actionable Insights”

COMPONENTSA huge gain in Productivity

Component Assembly and Mash-up• Web Services • Google Maps, Twilio, Facebook, etc.• Open Source • Databases, algorithms, reporting, etc.• SaaS application APIs • Salesforce.com, Dropbox, Google Apps, etc.

SOCIAL &GAMIFICATION

Social Features add Power• Many applications benefit from Social features• Consumer • Photo sharing • Dating • Hiring • Finding new music, restaurants, etc.• Enterprise • Sales • HR • Marketing• Consumerization of the enterprise

Gamification• Use to encourage engagement and usage

SUMMARYA World of new Challenges

Many Choices• Languages• Architecture• Components• Data Storage• Features• Security

With Power comes Responsibility• A key part of the job of an Architect / Developer: Making architectural choices• Above all else: meet the business needs • Time to market • Flexibility • Scalability • Reliability • Security • Etc.
