A website's performance can be measured using metrics. Metrics provide information on what is working, what is not, and where improvements are needed. Unlike numbers, spreadsheets, or data, it isn't as complicated or as time-consuming to use. For observability in marketing, website metrics that measure user engagement are vital. By analyzing metrics, the marketing department will be able to determine what web pages are not providing the company with value.

Before we take a deep dive into the ways to achieve observability, it is important to understand what observability is and how it is achieved. Frequently, observability is confused with monitoring. Observability provides end-to-end visibility into a system’s internal health by using the data it generates: logs, traces, and metrics. In a multi-cloud environment, observability enables you to detect and resolve anomalies.

Let’s look at IllegalArgumentException, which is one of the most common types of exceptions that Java developers deal with. We’ll see when and why IllegalArgumentException usually occurs, whether it’s a checked or unchecked exception, as well as how to catch and when to throw it. We’ll use a few examples based on common Java library methods to describe some of the ways to handle IllegalArgumentException.

The book is done. The book is FINISHED. There will be no more writing of the book! Holy macaroni. If you think you might be sensing just a SMIDGE of relief, you wouldn’t be wrong. We started writing this book, Observability Engineering: Achieving Production Excellence, three whole years ago, in the summer of 2019. Remember that?

The acceleration in digitalization, also due to the pandemic, has brought an organization’s business and IT teams and strategic goals closer together than ever before. Chief Information Officers (CIOs) have existed since the early 1980s and, until recently, their typical role was primarily focused on managing the technology infrastructure. But in a post-pandemic world, that role is now expanding beyond traditional IT responsibilities.

The Java Collections Framework was a huge leap forward when it was introduced as part of Java 2 (JDK 1.2). Thanks to the included collection classes we finally moved beyond the limits of Vector and Hashtable to more mature and generic solutions. With the introduction of streams and functional concepts in Java 8 the framework took everything to the next level. One of the core principles underlying the framework is coding to the interface.

Having enough time available is a struggle we all experience. Technological innovations enable us to develop and deploy software at lightning speed: Sometimes we can push more to production than our organizations’ IT environments can handle. At the same time, we want to increase customer satisfaction by reducing downtime. But how are you going to keep customer satisfaction rates high if a large majority of incidents are caused by changes?

When you migrated critical infrastructure to the cloud, what were your goals and expectations? Odds are, you hoped leaving on-premises infrastructure would produce significant organizational benefits. You probably figured you’d streamline operations and reduce management overhead. You felt you’d have an easier time meeting business goals. Perhaps most important of all, you likely expected your environment would become less complex, and even cost less to operate.
