Data Mesh Principles and Logical Architecture

 Data Mesh Principles and Logical Architecture The great divide of data What do we really mean by data? The answer depends on whom you ask. Today’s landscape is divided into  operational data  and  analytical data . Operational data sits in databases behind business capabilities served with microservices, has a transactional nature, keeps the current state and serves the needs of the applications running the business. Analytical data is a temporal and aggregated view of the facts of the business over time, often modeled to provide retrospective or future-perspective insights; it trains the ML models or feeds the analytical reports. The current state of technology, architecture and organization design is reflective of the divergence of these two data planes - two levels of existence, integrated yet separate. This divergence has led to a fragile architecture. Continuously failing ETL (Extract, Transform, Load) jobs and ever growing complexity of labyrinth of data pipel...

Security And Design

 Security And Design 


This last week I had the pleasure of wandering around Florida speaking with Dan Sandlin and David LeBlanc at a series of Microsoft architecture councils. For those who don't know David LeBlanc wrote the very popular book Writing Secure Code with Michael Howard. At each of the session I would do a talk / q&a on P of EAA (which got a JavaWorld award this week) and David would follow on security.One thing that interested me was that several people found the combination odd - implying that few people would be interesting in two such diverse topics. I think this is at the heart of problems about security in the industry. Security is seen as some separate topic area which sits in its silo. Yet security isn't something you can just add to an application by putting in a few encapsulated classes here and there. Security thinking should pervade a whole team - particularly on applications that are available on the internet or a large corporate intranet.To be fair there's room for people to focus on security issues. There's a lot of stuff to know about on security. But everyone should have a reasonable knowledge about it. As David points out: many eyeballs don't lead to secure code - you need many educated eyeballs. One of the things I like about David's attitude is that educating developers is a key part of the picture, with less emphasis on review steps with security groups.

ActivityOriented

  ActivityOriented Any significant software development effort requires several different activities to occur: analysis, user experience design, development, testing, etc. Activity-oriented teams organize around these activities, so that you have dedicated teams for user-experience design, development, testing etc. Activity-orientation promises many benefits, but software development is usually better done with   OutcomeOriented   teams. Traditionally, big businesses with large IT departments (Enterprise IT) have tended to execute IT development projects with a bunch of activity-oriented teams drawn from a matrix IT organization (functional organization). The solid-lined arms of the matrix (headed by a VP of development, testing and so on) are usually along activity boundaries and they loan out “resources” to dotted-lined project or program organizations. Common justifications for doing so include: It helps standardization of conventions and techniques in development if a...

Out come Oriented

 Out come Oriented  effort, better sales conversion, greater customer satisfaction, i.e business outcomes. Outcome-oriented teams are those that are mandated and equipped to deliver business outcomes, such teams have people with the capability to carry out all necessary activities to realize the outcome.. By contrast,  ActivityOriented  teams are neither equipped nor mandated to do so. They can only perform one of several activities required to realize an outcome. A mandate to deliver a business outcome is very different from a mandate to deliver a certain amount of scope. Scope delivery is easy, relatively speaking. Outcome realization requires real collaboration between those who understand the problem and those who can fashion various levels of solution for it. Initial attempts at solution lead to a better understanding of the problem which leads to further attempts at better solutions. This doesn’t work where the product management organization is separate from t...

AlignmentMap

  Alignment maps are organizational information radiators that help visualize the alignment of ongoing work with business outcomes. The work may be regular functionality addition or technical work such as re-architecting or repaying technical debt or improving the build and deployment pipeline. Team members use alignment maps to understand what business outcomes their day-to-day work is meant to improve. Business and IT sponsors use them to understand how ongoing work relates to the business outcomes they care about. Here’s an example scenario (inspired by real life) that illustrates how these maps may be useful. A team of developers had inefficiently implemented a catalog search function as N+1 calls. The first call to the catalog index returned a set of SKU IDs. For each ID returned, a query was then made to retrieve product detail. The implementation came to the attention of an architect when it failed performance tests. He advised the team to get rid of the N+1 implementation. ...
