If you haven’t done so already, providing a testing environment for developers to easily test their functions with AWS solves most of these challenges and makes the required tooling similar to what’s required for operating microservices. These served as our benchmark when creating our Lambda monitoring extension.

HammerDB Variable or Step Workloads are an advanced testing feature that enables you to automatically vary the load on the database over a period of time. When taking this approach you would not focus on the test result but instead monitor the databases ability to cope with the variation in demand and transaction response times.

How would we test to see if there is any difference between a good sans serif and a serif typeface with users? And today, we still have type in a digital context, but it travels through cables, wirelessly on smartphones, and in virtual reality glasses in 3D. So scientific tests for typeface legibility are often full of flaws.
