Practical Event-Driven Microservices Architecture: Building Sustainable and Highly Scalable Event-Driven Microservices
by Hugo Filipe Oliveira RochaIn the simplest terms, event-driven architectures are like onions; they are manageable as a single layer (like a monolith) but when you get into them, they begin to cascade apart and you quickly realize that there are many complex layers (distributed microservices architecture). And that’s when the tears begin.This prescriptive guide takes you through the steps of moving a platform with millions of users from a monolith to a microservices event-driven architecture. You will learn about the challenges and complexities that arise in high-throughput environments that often contain upwards of hundreds of microservices. This book is designed to be your single best resource for learning how to apply event-driven architectures in real-world scenarios and offers hundreds of patterns to overcome the common and not so common challenges.While event-driven architectures have been the standard for decoupled, pluggable, evolutionary architectures for years, they have only recently been adopted by enterprises for the purpose of distributed microservices and there is little information about adopting them. Using them at scale can save valuable resources, but requires different considerations, including the added complexity of supporting several moving parts and getting the event schema right from the start in order to avoid large restructuring later on.Author Hugo Rocha understands that these kinds of challenges, as well as many others, need to be considered from the beginning, and helps teach you the mindset needed to create a deliberate strategy upfront. This book offers learning approaches and patterns to get you up to speed in order to sustainably build and manage event-driven architectures.What You Will LearnUnderstand the real-world challenges of event-driven architectures and the patterns to deal with those challenges and the trade-offs of each solutionLeverage the advantages of event-driven architectures to build scalable solutions and address legacy applicationsPlan successful future implementations to avoid common pitfalls and apply proven patterns to deal with challenges in a real-world platform with millions of usersDecide whether event-driven solutions are the right choice for the requirements at handDiscuss and understand advanced concepts about event-driven architectures Who Is This Book ForSoftware engineers and software architects. Anyone currently working with microservice architectures, primarily event-driven microservices, will greatly benefit from this book. Readers working with monoliths will benefit, as the book explores migration from a monolithic application to an event-driven microservice architecture.

Pro Active Directory Certificate Services: Creating and Managing Digital Certificates for Use in Microsoft Networks
by Lawrence E. HughesIn order to deploy and use Microsoft Certificate Services, you need to understand the fundamentals of cryptography, digital signatures, encryption, TLS, and S/MIME. It is also important to understand the concepts behind public key infrastructure (PKI). This book teaches you all the required background knowledge you need. Then it takes you deeper, step by step, teaching you how to deploy Certificate Services and configure it to issue various digital certificate types, complete with examples of using these certificates with IIS, Outlook, and Windows.Microsoft-based networks—on-premises, hybrid, and cloud-based networks—are used in companies of all sizes. Within them, there are many applications of digital certificates that can be created and managed by Microsoft Certificate Services. As security is more important than ever, and cryptography and PKI are fundamental to so many of these defenses, understanding Microsoft Certificate Services is becoming an increasingly more desirable skill. Most IT workers don’t realize the many uses and purposes of Certificate Services, especially within a corporate or government agency network, and how tightly integrated they are with the Microsoft Windows Domain style of networks and Active Directory (on-premises or cloud-based, including Azure, AWS, and Google Cloud Services). This book will teach you the gamut. You will appreciate the learning approach presented in the book, beginning with the basics (cryptographic primitives such as encryption and message digests), getting into combinations of primitives to accomplish specific things (such as digital signatures and envelopes), and then trying real-word systems based on digital certificates and PKI (such as TLS, S/MIME secure email, cryptographic authentication, and more). The book wraps it all up and teaches you how to deploy Certificate Services and issue the various types of certificates, including how they are used. What You Will Learn Understand basic cryptography (symmetric and asymmetric key encryption, message digests, and digital signatures and envelopes)Know how TLS, S/MIME, and cryptographic authentication workDiscover applications of cryptography related to secure servers with TLS and cryptographic (passwordless) authentication to online services including Windows and secure emailGet to know the common types of digital certificates, how to create and manage them, and examples of their use with IIS, Outlook, etc. Who This Book Is ForMicrosoft system and network engineers, security engineers, and CISOs.
