An IT Architecture defines the hardware and software structures of an IT System Solution to a Business problem:

The components that will be reused, developed or purchased

The relationships between components:ƒ placement of components on nodesƒ distribution geographically ƒ network connections and topologyƒ how they will be managed

How the components interact dynamically:ƒ interfacesƒ protocols

What is an IT Architect?

Not all IT Architects look like this!

Provides Vision and Direction

Defines Scope and Reduces Complexity

Analyses Required Functionality

Defines Strategy of Solution

Defines Rules and Policies

Makes and Records Formal Decisions

Bridges IT and Business

Has end to end responsibility over solution designs

Assist with providing estimates – Cost, Duration, Skills

The IT Architect defines - architects -- solutions to client business problems through the reasoned application of information technology.

They may also be involved in the integration of a broad variety of products, technologies and services, various systems and applications architectures, and diverse hardware and software components.

Has extensive knowledge of systems, architectures, systems management, networking, network computing and application design techniques.

Is able to identify evaluate and select the elements of the solution which best meet the needs of the client.




Introduction to Gisela and Carolyn

Gisela Lotringer I’ve been in the IT industry since the ’70s, mainly with IBM, which I joined as

a junior staff member in a support group. In those days I worked with different aspects of mainframes, and later moved into Unix, followed by a career as an IT architect. It’s been a very stimulating career.

I work with many different clients, helping them to run their IT departments more effectively and efficiently.

I’m a mother of two and grandmother of two, and enjoy wildlife, cooking and reading.

Carolyn Matthews I joined IBM as a graduate, I started my career within IBM as a network

specialist. I then moved into the IT Architecture field.

I work within the City of Johannesburg (CoJ) which is a local government department. I am the CoJ enterprise architect as well as the CoJ architect team lead. I am a co-author of an IBM Redbook - TCP/IP Tutorial and Technical Overview. I am currently completing my Masters of Commerce degree specialising in Information Systems.

I am getting married in November, I enjoy adventure sports and having fun in general.

IT architectures are required to make sure that we create workable solutions that meet business needs

Architecture assists with translating business

requirements into workable and holistic architectures/solutions to suit the business requirements.




There’s rarely one single “correct” solution, each solution is influenced by the current requirements and environment.

Architecture provides a set of laws/boundaries for solutions, to ensure that all components of the solution will work together.

Catalogs, provide detailed specifications of the available parts together with a variety of alternative products implementing those specifications; plus recommendations on

how to use these parts (reference architectures).

Solutions to many different requirements, all built from the same common collection

of parts, each designed according to accepted standard reference architectures




IT Architecture must consider the views of different users and their needs

Systems Management View

User / Information

View

Content Management View

Data View

Business View

How do we integrate with external systems and databases?

What types of content, how is it maintained, published, and distributed?

How do you manageand administer theinfrastructure and the application?

What information needs to be made available, to

whom, and how?

What infrastructure do we need to provide the

required Service levels?

What are the security and privacy requirements for

the infrastructure and applications?

What processes, information, roles and

locations must be addressed?

FunctionalView

What are the data elements, where stored,

and how are they accessed?

Each view has a different architectural representation, just as a electrical wiring diagram is different from the interior designer’s “picture”.

How do applications support the required functionality?

There are many specialised skills required to create a building architecture and the same applies to an IT solution

Integration (data, application)

Systems Engineering and Architecture




The systems engineering and architecture discipline

Wikipedia: Systems Engineering

A branch of engineering whose responsibility is creating and executing an interdisciplinary process to ensure that customer and stakeholder's needs are satisfied in a high quality, trustworthy, cost efficient and schedule compliant manner throughout a system's entire life cycle, from development to operation to disposal.

This process is usually comprised of the following seven tasks:

State the problem, Investigate alternatives, Model the system, Integrate, Launch the system, Assess performance, and Re-evaluate.

Source: http://en.wikipedia.org/wiki/Systems_engineering

Systems engineering and architecture discipline.

The systems engineering and architecture discipline is a full lifecycle and interdisplinary approach and a means to enable the implementation of successful systems.

Systems engineering and architecture discipline focuses on defining customer needs and required functionality early in solution design and the development cycle, eliciting requirements, and then proceeding with design synthesis and system validation while considering the complete problem.

This discipline considers both the business and the technical needs of the customers and stakeholders with the goal of providing quality solutions or products that meets user needs.




The road towards being an IT Architect

IT Architecture is a Profession – like Lawyers, Chartered Accountants, etc.

Formal Education

Apprenticeship – practical hands on client projects.

Experience - technical and consulting, project management, customer relationships, successful architecture implementations

Breadth of knowledge - Infrastructure, applications, how business works, negotiation

Formal Requirements – IBM certification/accreditation training path, The Open Group Certification process.

“If you don’t know where you want to go, any road will do.And if you don’t know where you are, a map will not help!”




What are the characteristics of an IT Architect?

Has skills and experience of producing architectures, backed up by appropriate technical skills and experience, including technical breadth

Works in a disciplined, method driven manner

Has some full life-cycle experience i.e. through bid, design, development, test, deployment and support stages of a project

Has good Leadership skills

Has strong personal and professional skills

Has valued skills and experience in one or more customer industry segments
