● Technology decisions to realize business goals
● Architecture that supports a massive number of users
● Supports a highly efficient & end to end automated
infrastructure
● Automatically scales up or down from a capacity,business
process perspective
● Service Oriented Infrastructure & Architecture
● Architecture supports continuous velocity of change,
embraces risk and promotes Dev-Ops collaboration
● Typically built on Open Source
● Result in tremendous business agility

5. THE SEVEN NEW PARADIGMS
ACROSS ENTERPRISE
ARCHITECTURE

6. RED HAT CONFIDENTIAL | BRAND6
The Old Datacenter vs The New
Cloud (Private, Public or Hybrid)
Paradigm Old Datacenter The new Cloud (Private, Public or
Hybrid)
Infrastructure Proprietary OS/hardware & Virtualized to
some degree
Commodity hardware, just enough OS &
highly automated leveraging Cloud
technologies (IaaS – OpenStack), Config
mgmt tools & Hybrid Cloud Mgmt
Changing unit of abstraction Bare metal workloads, VMs VMs, Containers (Docker/LXC) and a
hybrid of both; Just enough OS;
Application development Packaged apps, monolithic technologies,
manual development
SaaS, Lightweight containers, Open
Source frameworks, fully automated
PaaS
Integration Tight integration, some usage of ESB Service patterns, loose coupling and
SOA componentry
Development Methodology Manual development DevOps (CI/CD) and Automation across
the stack
Application Agility Rules, Integration and BPM intertwined
with the application
Usage of Business Rules, Lightweight
mediation and BPM – embedded or
standalone
Data integration Brittle/ Spaghetti integration Usage of data virtualization, in memory
data grids, integration with Big Data
frameworks
