DevOps is speeding towards the IT world like a freight train and the hype around it is deafening. There is no reason to be afraid of this change as it is the natural reaction to the agile movement that revolutionized development just a few years ago. By definition, DevOps is the natural alignment of IT performance to business profitability. The relevance of this has yet to be quantified but it has been suggested that the route to the CEO's chair will come from the IT leaders that successfully make the transition to a DevOps model. If this still seems foreign to you, I recommend reading up on DevOps Blog from IT Revolution, the OpsCode Blog, and check out The Phoenix Project. Despite all the talk around simple monitoring tools, breaking through the walls between Dev and Ops still poses a real challenge. This is because of a misunderstanding around Operations real purp...

Continuous Innovation | @DevOpsSummit #DevOps #CD #ContinuousDelivery

Transformation to Continuous Innovation and Optimization Businesses have always had to transform to find better and more efficient ways to deliver value faster to their users, customers or consumers. The motivating factors are shorter lead times, automated and streamlined value flow, as well as reduction of overall costs and bound capital, requiring enterprises to transition to a continuous innovation and optimization model. Prominent examples can be found when studying the last decades in the automobile industry with Toyota and their way of optimizing and automating their end-to... (more)

We analyzed some of these long running and failing transactions and in this blog I present my analysis and hope it will be beneficial for other MS CRM Developers. Quick Overview... (more)

The Problem with SLA Monitoring in Virtualized Environments

Because virtual machines work by time-sharing host physical hardware, a virtual machine cannot exactly duplicate the timing behaviour of a physical machine. This leads to the timekeeping problems explained in the VMWare White Paper about Timekeeping in Virtual Machines that results in inaccurate time measurements within the virtual machine. This affects ALL performance metrics that rely on the operating system clock time to keep track of time which includes system counters like CPU or I/O Utilization. Performance Management solutions therefore run into the problem that the monito... (more)
