TOGAF: Practical Implementation-3: Requirement Gathering-Information Systems Architecture, Technology architecture and Opportunities=> Solution

TOGAF: Practical Implementation-3: Requirement Gathering-Information Systems Architecture, Technology architecture and Opportunities=>  Solution
Once we have created business principles and we know Business goals and drivers, we now have an idea what is the issue we need to solve. In other words we now know what the solution should address.
So we go to next step.
When we are talking about Information systems architecture and technology architecture, we need to understand that instead of focusing on technology, the focus should on solving the business problem.
It can be broken into Functional and Technology View or strategy.
For the Functional strategy

We need to FIRST ask what the solution should do.
§  How will it be used?
§  What services will it provide?
§  What information will it provide? To whom?
§  Who are the users?
§  What qualities must the solution have?
Here we are thinking from the end user perspective.
As in the Business Architecture we asked the question WHY, In this we need to ask WHAT
An example
Business
- why

Business goals with associated metrics (in no particular order)
·         Strengthen the team and make sure that they are capable to provide satisfied IT service system by end of 2014 (focus on team building, serving for. (BG1)
·         Expand service capability
o   We categorize our services components hierarchically into physical groups and logical groups, to minimize business impact to each other (e.g. to avoid minor business transaction to impact the key business)
·         We ensure customer understands total offering by end of 2014.
·         Customer-care process to be in place and implemented by end of 2014.
·         Internal operation process to be in place and implemented by end of 2004.
·         Cost-effective IT investment aligned with business strategy
o   BG1
o   Scalable architecture design to maximize the utilization of IT investment.
·         SLA is defined and implemented by end of 2014.

§ 
Functional principles
- what

Customer Care
·         Quickly respond to service requests from customers, and give feedback in time
·         Show the hospitality of kindness, care and patience, use simple, standard and professional language
·         Customers can get required information through a simple process

SLA (Service Level Agreement)
·         SLA must be categorized and negotiated with customers, then documented

·         SLA should be evaluated, traceable, operable and measurable


·         Make SLA knowledge popular and acceptable in UTStarcom


IT Operation Process
·         Establish and introduce/advertise service oriented processes for IT Operations
·         Processes of IT Operations should be simple, clear, operable, and can be tracked easily
·         Periodically review processes of IT Operations



§ 





Technical Strategy/Technology Architecture

The technical view asks how the solution should work.
§  How will the solution be structured and constructed?
§  What are the interfaces and other constraints?
§  What applications and data are needed?
§  What does the infrastructure look like?
§  What technical standards will apply?
§  How will the system qualities be achieved?
This is the place of Architects and designers. Here the high level solution and Defines the structure of the solution from a constructor’s perspective.
For example
Technical principles
- how
Networking
·         Network (LAN and WAN) must be stable and reliable
·         Network Bandwidth should meet requirement of business growth
·         Set subnet reasonably, ensure network security, efficiency and scalability
System
  • Improve the scalability of servers and storage

  • Improve scalability of system
  • Improve performance of system
  • Improve the efficiency of system backup and recovery


IT Management
·         We should have an integrated IT management platform for global network, system and application
·         We should have an integrated report system for IT management
·         We should have a tool for monitoring and managing end user/client devices
·         IT management platform should be integrated with helpdesk platform

o 




The final part of the whole solution is Implementation strategy
The implementation view asks with what the solution will be built.
§  What specific products and components, from which vendors, are needed to build the solution?
§  How will the solution be developed and deployed?
§  What timeframes are “frozen” (not available for deployment)?
§  What validation methods will be used?
§  How will the solution be managed?
§  What is the source of funding?
This is from Deployers Perspective
Implementation principles
- with
IT Operations
·         Strictly follow the change management process during IT operations
·         Unified role and responsibility definition for all management processes
·         Implement job role backup policy
·         Establish the mechanism to conduct customer satisfaction survey

Product Selection
·         The price performance must be optimized

·         Products must be manageable and securable

·         Products must have good Brand name and direct post-sale service


Data Center Implementation
·         Design project plan and follow the plan strictly
·         Reduce the impact to end users during implementation
·         Reduce downtime during system relocation

Once you have all these information, Solution is a piece of cake

Data Center Migration

Note: This blog is written with the help of my friend Rajanikanth
Data Center Migrations / Data Center Consolidations
Data Center Consolidations, Migrations are complex projects which impact entire orgnization they support. They usually dont happen daily but once in a decade or two. It is imperative to plan carefully, leverage technology improvements, virtualization, optimizations.
The single most important factor for any migration project is to have high caliber, high performing, experienced technical team in place. You are migrating business applications from one data center to another and there is no scope for failure or broken application during migration. So testing startegy should be in place for enterprise business applications to be migrated.
Typical DCC and Migrations business objectives
Business Drivers
·Improve utilization of IT assets ·DC space & power peaked out - business growth impacted ·Improve service levels and responsiveness to new applications ·Reduce support complexi…

HP CSA Implementation

I know the above picture is little confusing but don’t worry I break it down and explain in detail. By the time I am done explaining you all will be happy. HARDWARE AND SOFTWARE REQUIREMENTS 1.VMware vSphere infrastructure / Microsoft Hyper V: For the sake of Simplicity we will use VMware vSphere. We Need vSphere 4.0 /5/5.5 and above and vCenter 4.0 and above ready and installed. This is the first step. 2.We need Software medias for HP Cloud Service Automation, 2.00, HP Server Automation, 9.02, HP Operations Orchestration (OO)9.00.04, HP Universal CMDB 9.00.02, HP Software Site Scope, 11.01,HP Insight Software6.2 Update 1 3.DNS, DHCP and NTP systems are already installed and configured. NTP information should be part of VM templates 4.SQL Server 2005 or Microsoft® SQL Server 2008 or Microsoft® SQL Server 2012 , Oracle 11g, both 32-bit and 64-bit versions may be used for CSA database.
5.We will install  HP Cloud Service Automation, 2.00, HP Server Automation, 9.02, HP Operations Orchestra…

Openstack- Its importance in Cloud. The HP Helion Boost

Every enterprise expects few things from cloud computing, mainly:

· Auto scaling: The workload should increase and decrease as needed by the IT environment.

· Automatic repair: If there is any fault or crash of the application or the server, it automatically fix it

· Fault tolerant: The application or underlying technology is intelligent enough to make itself fault torrent

· Integrated lifecycle: It should have integrated lifecycle

· Unified management: Its easy to manage all different aspects of technology

· Less cost

· Speed


Its year 2014. till now only 5% to 7% enterprises are using cloud computing. Such a small number. Its a huge opportunity and a vast majority for anyone who is interested in providing cloud computing services.
Current IT environment is very complex. You just cant solve all your problems with cloud computing.
There are legacy systems, databases, data processors, different hardware and software. You name it , there are so many technology available in just o…
