Leapfrogging with legacy

Leapfrogging with Legacy…
or bite the bullet?

ARCHITECTING A BALANCED PRODUCT
PORTFOLIO FOR, SMALL, MEDIUM, LARGE.

The Week the Cloud Won
IT players "who thought they had...years to adjust to the new
realities...having a really bad day”
by Quentin Hardy NYT

Perspective
 2012 looking like 1992
 Previous era synchronous technologies, Voice, Windows, stick
around, but not suited to asynchronous global business
communications.
 The Browser, having successfully incubated JavaScript as the
canonical era asynchronous development platform, now fading
away.
 User experience, ushers in Apps economy, iPAD, Android,
HTML5.
 Client-side JavaScript now moving to server-side for
asynchronous collaboration at scale, NodeJS, WebSockets,
push notifications.

How to pull a Kobayashi
Maru with legacy?
A no-win situation caused by a set of rules that can
only be won by changing the rules, in effect,
cheating...

Solving the Kobayashi Maru…
A Starfleet training exercise designed to test the character of cadets in the
command track ...

Lets cheat..
 Training exercise: By way of my work and development
community involvement I’m constantly learning latest
technologies, new approaches and rubbing shoulders
with top practitioners.

 Change the rules: A polyglot PaaS approach
 Test the approach

Design
STORIES, VISUALIZATION, USER EXERIENCE

Have you ever wondered
where things come from?

Product Development

WIINING CUSTOMERS WITH CONVENIENCE OVER SOPHISTICATION,
USER EXPERIENCE OVER FEATURES

Software architecture
priorities evolved

Development
 Web Dev UX NOT UI Dev
 Beautiful design practices for
communication and viral
adoption

 API easy to adopt
 Sample App – code pushed
to GitHub

 Twitter API
 Exploreable
 Predictable
 Consistent

Why polyglot PaaS approach
 Polyglot (multi-technology)
 Polystore (multi-datastore)
 SQL, NoSQL, NewSQL

 PaaS
 NoOps, No Admin, Automated scaling
 AWS / Azure / Heroku (CouchDB)

 CouchDB
 Part of the NoSQL group of data stores and is designed for local
replication and to scale horizontally across a wide range of devices.
 Supported by commercial enterprises Couchbase and Cloudant.

 User Experience: Expedia / Cassandra
 price book (2 billion) wide rows are not always bad

Product coexistence-2
 SaaS biz apps generally use multitenant database.
 Disruptive to back-fit legacy with MT database.
 Another way of filtering identity to data views?
 Granular data social objects: PaaS approach
 Database.com (live), Pardalis.com (patents)

Summary
Tier 1- 2 Tier 3
 Assumes legacy apps  Code API Mobile reads
already supported on
industry standard VM  Select cloud sign-on and
hypervisors. VM hosting vendor
 Assumes customization  App to learn and
by SDK or DB, making neutralize new entrants
legacy product on
premise.  Select granular data filter

 Develop API for writes
 Iterate

Continue to transformation..?
Following may be phased in as market pressure grows

CouchDB: Cloudant.com
 Cloudant's hosted data layer service makes clustering
similar to Voldemort, Cassandra, or Riak, as it
implements a version of Amazon's Dynamo

 Rest API http: post, get, put, delete (CRUD)
 Distributed Architecture with bi-direction sync
replication and off-line replication.

Conclusion
 Creative Polyglot PaaS approach seeds tier 3.
 Feature deep tier 1 and 2 not disrupted.
 Implementation details are product specific
 Boilerplate with polyglot PaaS based on CouchDB
(other polyglot polystore solutions may fit better)

 Each product development team to follow the
prescribed methods (no bottlenecks expected)
