Agenda

➢ Next generation business – highly distributed, dynamic applications – based on 'services'

➢ Design / Architecture Patterns provide re-use and accelerated development

➢ Infrastructure virtualization and “refactoring” improves business agility

Next Generation Applications

A Shift in IT – Today's reality

● IT reacts slowly to business requirements, has unpredictable reliability, inefficient

● IT is a cost center● IT organization owns IT strategy

– Tomorrow's vision● IT detects/acts in real time to business, reliably, with costs

correlated to business priorities ● IT is a profit center, providing value based business services,

that drive business, focussed on business strategy– “How can we save money and enable new business?”– “We need a roadmap and specific technology injection points?”

Shifting to the Network Enterprise- Dynamic Mapping of Applications & Infrastructure

● Applications are assembled (via co-ordination / orchestration) of distributed services– Application was: webserver / database, now Application is: “Amazon.com”– No one writes the whole application, components delivered, imported

● The “computer” is assembled from heterogeneous compute & storage & network resources

● This requires a real-time approach to architecture

Using 'Patterns' to Architect Services

Sun Proprietary Page 10

Services Oriented Architecture (SOA) - a shift to 'business' programming

● Loosely coupled, Coarse-grained,● Process coordinated, business aligned, ● Network-based shared services ● SOA as an architectural style may best be

realized using Java web services● But how do we

– Refactor and map business processes to coarse grained SOA processes?– Architect re-usable services & systems?

Sun Proprietary Page 11

Patterns – provide architecture re-use at multiple levels

Design Patterns● Used to express detailed

functional design

Architecture Styles● Abstract common

architectures & requirements

Micro-architecture● Describe sub-

architectures

Build Patterns● Structural

implementation

A pattern describes :– a problem which occurs over and over

again in our environment– the core of the solution to that problem,

in such a way that you can use this solution a million times over, without ever doing it the same way twice

Harvesting & refactoring Admin Use Cases / Patterns

For Each Service• Determine and set up range of

IP addresses

• Physically or logically setup LAN

• Physically and logically layout storage

• Setup firewalls

• Setup load balancing clusters

• Setup HA clusters

• Setup mid-tier clusters

• . . .

Provision server (physically acquire)• Connect to network— acquire IP address, etc.,

NIS name, DNS name, LDAP name, etc.• Install OS and relevant patches (the latter can sometimes take longer

than the OS install!)• Install and configure Volume Management (optional)• Install and configure 3rd party file systems (optional)• Install clustering software (optional)• Install management framework probes/agents, etc.• Install Application software (traditionally to

local storage)• Tune O/S for software (rare these days except for DB)• Configure application software part 1— bind to the O/S, i.e., use IP

addresses, etc.• Configure application software part 2— give it an identity in terms of the

service (database name, etc.)• Start the application

• . . .

Transforming to Enterprise Agility● SOA (Services Oriented Architecture)

– Coarse grained, loosely coupled, business services● Pattern based design

– Design Re-use of low-level design patterns, micro-architecture building blocks, SOA business models

● Platform Rationalization– Consolidation, standardization, automation

Cost centric computing● Silos● Low utilization (~15%)● Static design● Scale diseconomies

Service centric computing● Virtual resources● Hi utilization (>40%)● Dynamic design● Economies of scale
