  • Thinking about the Systems Modeling Language and the Datacenter

    For a while, developmental and operational environments have rarely worked well together. Developers design something and then throw it over the wall for the infrastructure team to design an environment to support it. Then it’s thrown over the wall for operational teams to deploy and monitor it for the rest of its life. Microsoft is proposing a new standard (SML) to change this.
  • Swarm

    There are tremendous opportunities and cool new services coming from Web 2.0 like services today which our user base is becoming more excited about. However, as we all know, we must understand the impact of these services on the integrity of the information...
  • Analyzing Datacenter Complexity

    Some have asked about what are good approaches for examining the complexity (or trying to figure out how to associate operational staffing numbers for a specific datacenter) tough question. Here is what I used in the past to decompose this question...
  • SAAS, interfacing with services in the future.

    Many are promoting two core characteristics of SAAS today: the ability to provide a multi-tenant service model and the utilization of AJAX as a vehicle to provide better than basic browser capability to diverse browser products. I don't completely agree...
  • When to promote more tiers in your architecture.

    One question I often hear is: "How many physical tiers should be designed into an infrastructure architecture." You have to understand the customer's architectural perspective for the life of the application. Especially for systemic quality...
  • Q/A Solution Architecture for Infrastructure Architects and the MCA Program

    In December, I received an email asking how much should an infrastructure architect understand about solution/application oriented architecture. Also, the architect expressed interest in the MCA program for infrastructure architects. Yes, candidates...
  • Developing Architectural Perspective

    Often, good architecture decisions come from good architects. Most people have generally agreed that architects with strong technical and business knowledge and experience are highly qualified professionals. However, knowledge and experience rarely correlate...
  • Bringing my Blog back to life

    ok, I know, it's been a long time since I've posted. I apologize. I received my far share of complaints because of this neglect. I've been caught up on research and writing and did want to start discussing these things until I received a green...
  • Architecting a solution's infrastructure for your operational and business success

  • Infrastructure Architecture and ADAM

    Many have discussed the benefits of utilizing ADAM (Active Directory Application Mode) for their enterprise solutions. With introduction of ADAM, developers now have the opportunity to utilize powerful directory capabilities without requiring extensive...
  • Opinion on Firewalls: an component in a larger security architecture plan

    Firewalls are simply physical security components of an overall security architecture. Firewalls can be helpful. However, they do not solve, by themselves, all of a corporations security needs. Firewalls can do the basics: trap, analyze and then, allow...
  • What's wrong with Complexity?

    Many engineers have asked: what is wrong with complexity? Doesn't it lead to data center designs which are more precise and accurate? Doesn't it lead to data center designs which more optimally capitalizes on technical innovation? Of course it does...
  • How do we measure the success of an Infrastructure Architecture?

    While this is something we're all working on refining, here are some of my random thoughts: Thought One: I think all infrastructure architectures should be documented and categorized for quarterly peer review. During this time all initiatives should...
  • Measuring the Success of Infrastructure Architects

    Executives have often asked what are my thoughts on measuring the performance of their Infrastructure architects. So here are some of my thoughts. As this profession begins to mature, I'm sure there will be many more new ideas and refinements. I look...
  • Virtualization: A Pandora's box or data center panacea?

    Virtualization has received a great deal of attention from the press during the past couple of years. We have seen many products promoting storage virtualization, network virtualization and computational virtualization. Furthermore, with the promotion...
  • DSI: the basics

    As most of you know, a data center manages information. It processes it, communicates it and stores it. It does this with a variety of technologies, processes and role skill development. Currently, the growth and volume of applications and Services...
  • Advice for a new infrastructure architect college student.
