Breaking Down Enterprise Silos in the Cloud Are you recreating existing technology silos in the Cloud? If so, your entire enterprise investment in the Cloud is at risk. From the perspective of IT, organizational silos seem to be the root of all problems. Every line of business, every department, every functional area has its own requirements, its own technology preferences, and its own way of doing things. They have historically invested in specialized components for narrow purposes, which IT must then conventionally integrate via application middleware --- increasing the cost, complexity, and brittleness of the overall architecture. Now those same stakeholders want to move to the Cloud. Save money with SaaS apps! Reduce data center costs with IaaS! Build a single Private Cloud we can all share! But breaking down the technical silos is easier said than done. There are endless problems: Static interfaces. Legacy technology. Inconsistent policies, rules, and processes. Crusty old middleware that predates the Cloud. And everybody still has their own data model and their own version of the truth. The Cloud alone can't solve these complex challenges. We need a better approach to implementing technology that brings silos together, while allowing the personalization and customization that meets stakeholder needs. It’s time to rethink how we handle both data and code to align with the storage and processing model of the Cloud: distributed, horizontally scalable, and event-driven. We need an intelligent, active approach to building and running applications that is both dynamic and inherently Cloud-friendly. Attendees of this session will learn: * How organizational silos, application silos, and infrastructure silos limit business agility * Why moving existing applications to the Cloud won't break down silos, and in fact, will often make them worse * A novel, holistic approach for resolving the technical challenges with breaking down silos as enterprises move to the Cloud

3. Problems of
Organizational Silos
• Every line of business,
department, functional area
has its own requirements, its
own way of doing things
• Must invest in specialized
components for narrow
purposes
• IT must integrate everything,
increasing cost, complexity, &
brittleness

4. Silos on Top of Silos
• Organizational silos
– Lines of business,
departments,
geographic locations,
etc.
• Application silos
– COTS apps / bespoke
apps for different
departments
• Infrastructure silos
– Varied data centers &
rooms, heterogeneous
platforms, & Cloud!

6. Cloud is No Panacea
• Move to the Cloud! Save money!
• But…problems with technical silos persist:
– Apps that aren’t architected for Cloud
– Static interfaces
– Legacy technology
– Inconsistent policies,
rules, & processes
– Crusty old middleware
that predates Cloud
– Diverse versions of
truth
– Semantic interoperability
issues

7. The Cloud Agility
Challenge
• Application silos in the
Cloud are still silos
• “Cloud” more than IaaS
+ PaaS + SaaS
– Extend to mobile,
Internet of Things, etc.
• Enterprise context
– Dealing with legacy
– Hybrid scenarios
– Complex governance &
compliance challenges

8. Business Agility
• Responsiveness
– Tactical value
• Resilience
– Risk mitigation
• Innovativeness
– Strategic value

9. Enterprise as Complex
Adaptive System
• Business agility is
property of organization
as a whole, hence an
emergent property
of the organization
• Enterprise is system of
systems that exhibits
emergent properties
• System of people and
technology
– Traffic jams
– The wave

10. The Secret to Emergence
• Rules that affect behavior of
component systems can be
very simple
• Emergent behaviors often
unpredictable
• Try something, see what
happens, repeat
• Feedback loops & iterative
approaches

11. Governance as Agility
Enabler
• Simple rules & policies lead to
complex emergent behavior
– Which ones lead to agility?
• Agility vs. Chaos
• Levels of governance
– Low-level rules & policies
– Departmental
– Organizational
• Governance has negative connotation
– Reputation for limiting productivity
– Governance, Risk, & Compliance tools integrated in
traditional manner

12. Limitations to Business
Agility
• IT as the “bad guy”
• EA buried in the IT
department
• Ivory tower architecture
• Silo mentality
– Not invented here
– Can’t wait for IT
– BYOD to BYO-everything
• No Agile Architecture

13. What is Bloomberg Agile
Architecture?
• Bloomberg Agile Architecture
reinvents Enterprise Architecture
(EA) to drive business agility across
the organization
• NOT: software architecture compatible
with Agile development methodologies
– Won’t support the organization’s agility
requirements
• New architecture paradigm
• Style of EA focused on architecting agility

15. Cross-Cutting
Architecture
• Organization,
process,
applications, data,
infrastructure
• Role for Enterprise
Architecture
• Wakeup call for EAs
& their
organizations
• Essential for
addressing silos

16. Extending the Agile
Manifesto
• Individuals and interactions over
processes and tools
– As a system of people & technology,
the enterprise is more about people
• Working software over comprehensive
documentation
– Technology must actually work to
enable agility
• Customer collaboration over contract
negotiation
– Slice across the silos
• Responding to change over following a
plan
– Architect for change

18. From DevOps to “BizOps”
• Before: dev chucking code to test, then over wall
to ops
• Now: continuous test, continuous deployment
• In progress: responsiveness to continuous
requirements change & variation

19. Avoiding the Overbuilding
Problem
• The challenge of minimum viable design
• Code to metadata to unified system abstraction
• If you have an overbuilding problem, you’re
doing Agile Architecture wrong!

20. What are You Writing?
• Code?
– Least flexible, most susceptible
to overbuilding, reuse always a challenge
• Metadata via declarative programming?
– Abstracts code, but leads to complexity shell game
• Abstract models?
– Essential for
implementable
Agile Architecture,
but vendors
largely fall short

21. Assembling the Pieces of
Agile Architecture
• Architecting for change
requires working at higher
levels of abstraction
• Abstract models resolvable
to capabilities at run time
– Dynamic coupling
– Dynamic schemas
– Extreme late binding

22. Dynamic Coupling
• Tight coupling
– Must code all nodes at
once
• Loose coupling
– Interfaces abstract
underlying code
• Dynamic coupling
– Interfaces resolved at run
time

23. Dynamic Schemas
• Rigid data schemas
– Entity-Relational
Model, XML Schemas
• Schemaless data
– Problem of implied
schemas
• Dynamic schemas
– Metadata modeled at
design time, resolved
at run time

24. Extreme Late Binding
• Early binding
– Traditional integration
• Late binding
– Web Service discovery
– Content-based routing on
ESBs
– DNS resolution for RESTful
endpoints
• Extreme late binding
– Fully dynamic discovery
– Resolve URIs & metadata
references in real time

25. Dynamic Constraint
Satisfaction
• Governance as layers of policies & rules
• Need to calculate effective policy
• Cross-process, cross-organization, in & out of Cloud
• In real time

26. No Excuses!
• Business Agility
platforms are now
available
• Business wants agility
• IT can provide agility
• Architects should know
how to architect agility
