SQL Server Execution Plans, 3rd Edition
Every Database Administrator, developer, report writer, and anyone else who writes T-SQL to access SQL Server data, must understand how to read and interpret execution plans. My book leads you right from the basics of capturing plans, through how to interrupt them in their various forms, graphical or XML, and then how to use the information you find there to diagnose the most common causes of poor query performance, and so optimize your SQL queries, and improve your indexing strategy. You'll also learn how to take advantage of the Query Store and the latest optimizations, Adaptive Query Processing. Every day, out in the various online forums devoted to SQL Server, and on Twitter, the same types of questions come up repeatedly: Why is this query running slowly? Why is SQL Server ignoring my index? Why does this query run quickly sometimes and slowly at others? My response is the same in each case: have you looked at the execution plan? An execution plan describes what's going on b ...

Taking Kubernetes from Test to Production
With Kubernetes came many new concepts, particularly around networking and traffic management. Alongside these new concepts were entirely new classes of tools, designed for ephemeral, containerized, and distributed application deployments. In particular, Ingress controllers and service meshes did not exist prior to the Kubernetes era. Nor were Layer 4 and Layer 7 protocols and traffic typically managed from the same control plane. At a granular level, Kubernetes introduces new complexities around security and management. Simple tasks like load balancing are very different in a realm where infrastructure is 100% ephemeral and often moving constantly - both in terms of setting up new instances with fresh IP addresses and geographically moving around the globe. These new traffic management concepts and tools have the power to vastly improve developer experience and accelerate app development and delivery cycles through greater resilience, higher performance, and better security. But wh ...
