In a three-tier architecture involving a frontend system (FE), a middleware layer (MW) and a backend system (BE), the FE sends requests via the MW to the BE. However, the ML is not a pass-through component, rather it acts to decouple the FE and BE. The MW also acts as a secondary security layer, inspecting […]
The Fog of Experience
I still remember the early days when I first started out in tech. All answers were apparent and hardly was the ink dry on the request, and I was already delivering pieces of the solution. It was a kind of “Agile”; quick, and invariably, MVP. The success factors for me were essentially the functional aspects. […]
Kubernetes-to-AWS Security Bridge
In an ever evolving paradigm of virtualised infrastructure, seeking and sealing security gaps must be regarded as BAU.
Security in an interconnected, always-on (24*7), virtualised, digital world is not just important, it could be a game-changer!
Cloud Migration and Availability Index
The Cloud Transition The Cloud may not be in-your-face. But it is pervasive, and gradually taking over many aspects of our traditional IT systems. Companies are not yet making wholesale transitions from existing data-centres and on-premise assets to Cloud. However, when infrastructure reviews occur, whether to upgrade or add new resources, the Cloud beckons. Questions […]
Securing our Hybrid Cloud
In a previous article, “One thousand servers, start with one click”, I described the design and implementation of a simple hybrid-Cloud infrastructure. The view was from a high level, and I intend, God willing, to delve into the detail in a later instalment. Before that though, I wanted to touch on the subject of hybrid […]

1000 Cloud Servers: Start With One Click
Cloud and Open Source The arrival of Cloud providers and Infrastructure-as-a-Service (IaaS) has opened up options and possibilities for solution architects. Our company is working with a client on a major transformation initiative. Leveraging Cloud IaaS and open-source integration platforms, together we have explored options, built competence, and delivered incremental solutions while keeping costs to […]
Factory Approach to Service Engineering – Preamble
World of Perspectives We all see the world from different perspectives, and the sum of perspectives help us to get a better/fuller understanding of our world. In this article, we share a perspective on engineering services for business. This perspective can be summarised as: Intelligent Laziness – strategies to achieve equal or better productivity with […]
Factory Approach to Service Engineering – Business
From Technology to Business In a previous article, I looked at how some metaphors can be used to understand the engineering of software (services). Of the five listed below, I introduced the first four. Factory Pattern Framework Process Service The first three have a clear technical focus; the fourth is a gateway between the technical […]
A Simple DevOps Chain
A Pipeline of Tasks Illustrating a Simple DevOps Chain DevOps is the amalgalm of development activities and the business continuity provided by operations teams. It unites the efforts of what are still two teams, with different competencies, into one value chain. DevOps creates and sustains a unified process for transforming technical requirements into live code […]
Impressive Amazon Web Services: First Glance
Amazon Web Services: Background Amazon Web Services (AWS) have revolutionised the way we view IT provisioning. AWS makes so many things easier, and often cheaper too. The benefits scale from the SME right up to corporates; no segment is left out. Complexity is abstracted away, and with a little effort, large and/or complex systems can […]
