I recently joined two industry veterans and Dynatrace partners, Syed Husain of Orasi and Paul Bruce of Neotys as panelists to discuss how performance engineering and test strategies have evolved as it pertains to customer experience. Dynatrace news. This blog summarizes our great conversation for the posed questions.

Decades of poor architecture guidelines and lax developer discipline resulted in the commercial-off-the-shelf components of an ERP becoming inseparable from the custom code built around it. A basic premise is that there are alternatives to traditional "lift and shift" strategies by retiring legacy assets in a piecemeal fashion.

Otherwise, you’ll either get the implicitly generated move functions, or else requests to move will automatically just do a copy instead, since copy is always a valid implementation of move (it just doesn’t exercise the non- const option). Yes, in my view it does make it a buggy class that shouldn’t pass code review.

There aren't a lot of high cards we can draw, but playing them in the right combination offers us a strategy. Tool 1: Dolly the Sheep Companies that are heavily rule-based - think insurance - eagerly moved their business rules into code. It was easy to move into code; it's just as easy to move it back into human-readable format.

One of the several deployment strategies is the blue/green deployment approach: In this method, two identical production environments work in parallel. The new version of the application is deployed in the green environment and tested for functionality and performance. Both use the same database back-end and app configuration.

Any time you run a test with WebPageTest, you’ll get this table of different milestones and metrics. Note the bottom row shows me the Standard Deviation of the tests’ results. The whole point of the exercise that follows is to allow me to move quickly, spotting patterns from afar, and not having to do any slow or meticulous work yet.

In this study, the diagnosis and resolution of an outage in a global Internet service, Etsy.com, was explored in an effort to uncover which cognitive strategies (specifically, heuristics) are used by engineers as they work to bring the service back to a stable state. Gathering timestapms of changes made to application code during the outage.

There are many possible failure modes, and each exercises a different aspect of resilience. In the same way that we have moved from a few big software releases a year to continuous delivery of many small changes, we need to move from annual disaster recover tests or suffering when things actually break, to continuously tested resilience.

This is mixing concerns and leads to code that becomes strongly coupled, monolithic, hard to write, hard to read, hard to evolve, hard to test, and hard to reuse.
