As more organizations embrace microservices-based architecture to deliver goods and services digitally, maintaining customer satisfaction has become exponentially more challenging. Implementing service-level objectives (SLOs) has become a vital method for meeting service-level agreements that ensure great user experiences. A service-level objective is a key element within a larger service-level agreement, or contract of sorts, between a provider and a customer.

DevOps, as initially conceived, was more of a philosophy than a set of practices—and it certainly wasn't intended to be a job title or a role spec. Yet today, DevOps engineers, site reliability engineers, cloud engineers, and platform engineers are all in high demand—with overlapping skillsets and with recruiters peppering role descriptions with liberal sprinklings of loosely related keywords such as "CI/CD pipeline," "deployment engineering," "cloud provisioning," and "Kubernetes.

This is a synthesis of several recipes that I’ve modified over the years. I usually make a cake for the holidays. Growing up my mother made what she called a Dundee Cake, a round fruit cake with almonds on top. She would make it a month before, and soak brandy into it. My version avoids wheat and dairy, I use honey rather than sugar and I soak the fruit in spirits before I make it, then it’s good to eat a few days later.

As more organizations adopt cloud-native technologies, traditional approaches to IT operations have been evolving. Complex cloud computing environments are increasingly replacing traditional data centers. In fact, Gartner estimates that 80% of enterprises will shut down their on-premises data centers by 2025. This transition to public, private, and hybrid cloud is driving organizations to automate and virtualize IT operations to lower costs and optimize cloud processes and systems.

One of the routine operations when administering PostgreSQL is periodic updates to the database system’s architecture. PostgreSQL does a good job of allowing one to update a schema, add types, functions, triggers, or alter a table by adding and removing columns and updating column data types, etc., in a reliable manner. However, there is no built-in mechanism to help identify the differences, let alone generate the necessary SQL, to accomplish updates in an easy manner from the development

Southwest Airlines has made headlines in recent days for all the wrong reasons: bad weather impacted air travel, which required Southwest to adjust plane and crew schedules. Those adjusted schedules were often logistically flawed because the planes and crews matched at a specific place and time didn’t make sense in the real world. Making matters worse, those adjusted schedules had to be re-(and re- and re-)adjusted every time either the weather changed or operations changed (ie., more flight can
