Aggregated enterprise architecture wisdom
Enterprise-architectures should, in principle, apply to any enterprise, at any scale. But what happens when we scale our enterprise-architectures up to the ‘really-big-picture’ (RBPEA) level, with a literally global scope? What non-negotiable constraints would we hit up against? What corollaries would…
Do you recognize the continuous balancing of urgent vs. important matters? I am often confronted with urgent matters that need to be resolved quickly such as an escalation within a project, deadlines and engaging in interactions through meetin…
TOGAF doesn’t explain in much detail how you actually go about producing an Architecture Vision or Roadmap, and this can be particularly difficult if the future is uncertain or turbulent. This case study shows how one European telecoms company used the idea of a strategic staircase to supplement TOGAF.

The conference is packed with workshops, keynotes and customer presentations covering the fields of enterprise architecture, business transformation, and compliance. As you know, QualiWare wants to be your preferred platform when you do enterprise architecture, process improvement, compliance management, application portfolio management, business transformation, and more. The conference program has therefore been designed to offer […]

Private Database Cloud Services or Database as a Service(DBaaS) is no longer a new idea. Infact, it is quickly becoming the de facto standard for development and testingenvironments both on premises and in the public cloud. And while there are many use cases anddeployment options, overall database total cost of ownership and businessagility have benefited from a standardized approach to workloadmanagement. Whether you are a DBA, anoperations manager, or a CIO, you are well aware that business-driven interestin social, mobile, big data, and internet of things have caused an explosion ofdevelopment, data, and database workloads. The justification for database operations to pool resources andstandardize services has never been clearer – watch thiscustomer story (TRT1:30).
Today’s best practices in cloud architecture expect serverscalability, zero data loss resiliency, and most importantly workload securityand isolation through multitenancy. For database services, the architecturewould be incomplete if database operations did not also natively supportmultitenancy. Initial approaches for DBaaSwere limited since they only relied upon virtual machines for workloadisolation and database provisioning. As general technology containers, VMs hadno intrinsic understanding of database operations, so they were unable to optimizeperformance, scalability, and resilience as well as simplify databaseadministration efforts.
Today’s best practice for database cloud services overcomesthese limitations. The Oracle PrivateDatabase Cloud approach is both revolutionary and elegantly simple. By engineering multitenant capabilities throughoutthe Oracle database platform, the complete range of database operations andadministration can now be natively managed andwithout the overhead of a virtual machine. Oracle’s Private Database Cloud guarantees isolation and leveragesOracle’s strengths in reliability, scalability, security, and systemsmanagement. Large database estates also benefit from a host of relatedcapabilities, such as cost-recovery reporting, self-service management, andpublic cloud integration. You will findthat Oracle database platform is ideal for a standardized enterprise deploymentor cloud service, whether development/test or production – watch thiscustomer story (TRT2:17).
Oracle offers a reference architecture overview and Oracleproduct mapping for DBaaS in a private cloud deployment model. The approach and guidance offered is thebyproduct of hundreds of customer projects and highlights the decisions thatcustomers faced in the course of their architecture planning andimplementations. Oracle’s advisingarchitects work across many industries and government agencies and havedeveloped standardized methodology based on enterprise architecture bestpractices. Oracle’s enterprise architecture approach and framework are articulatedin the Oracle Architecture Development Process (OADP) and the Oracle EnterpriseArchitecture Framework (OEAF).

Finally the majority of CIOs have understood that it is not possible to drive market innovation with all their assets and instead concentrate on a two speed and often even on more speeds in their IT departments. Since this means that there are parts of the business that will get what want very fast and … Continue reading Architecture in a two speed IT department →
With a system landscape, being urgently needed (see previous post), we want the construction to be of low complexity and low risk. How do we go about this? I will claim, that one trained person with a focused effort can map a medium sized enterprise in not years, but in just one or two month! […]
A three dimensional representation can be rotated, sectioned, dis-assembled… so we can analyse it.
Architects generally wrestle with the problem of communicating their complex world of dependencies to stakeholders. Those that created the ArchiMate language hoped that making a better language would enable clearer communication. While ArchiMate does enable more precise communication than your average … Continue reading →
In the previous postings we zoomed in on developing “top-down” or “enterprise” models, laced with many practical tips to help practitioners to get started. In this post we tackle the other end of the spectrum, and discuss how to get started with “Bottom-up” or “solution” models. We will zoom in on several aspects, including structuring your models, and linking to your enterprise models.
At present we are told that that we will need to build more postmodern ERP systems consisting of a small core any many discrete services, an environment where we outsource as many discrete functions to specialised providers, but still retain all the data for data analysis. When you look at this many will instantly think … Continue reading The need for more data integration architects →
