Transitioning to DevOps requires a change in culture and mindset. At its simplest, DevOps is about removing the barriers between two traditionally siloed teams, development, and operations. In some organizations, there may not even be separate development and operations teams; engineers may do both. With DevOps, the two teams work together to optimize both the productivity of developers and the reliability of operations. They strive to communicate frequently, increase efficiencies, and improve the quality of services they provide to customers. They take full ownership for their services, often beyond where their stated roles or titles have traditionally been scoped by thinking about the end customer’s needs and how they can contribute to meeting those needs. Quality assurance and security teams may also become tightly integrated within these teams. Organizations using a DevOps model, regardless of their organizational structure, have teams that view the entire development and infrastructure lifecycle as part of their responsibilities. In this book, we introduce the DevOps culture, and the tools and techniques under this technical cultural umbrella. We explain microservice, containers, Docker Container, Kubernetes, etc., and the significance of these in adopting the DevOps culture for successful software development.

It's not new to us that microservices are changing the way we conceive digital transformation, as organizations embrace digital transformation. Every day, more and more companies are betting on microservice adoption, and there is a strong reason for this: business needs to evolve and change at a fast pace, in order to adapt itself to satisfy a demanding 2.0 digital customer's experience in terms of overall service quality. Ensuring that such a change occurs seamlessly and progressively is one of the goals for microservices, and designing and building a solid microservice architecture is the way to guarantee that this happens from inception, by observing principles, best practices, design patterns, and reference models. This book provides a comprehensive walkthrough across the different concepts, frameworks, methodologies, and architecture building blocks that make up a microservice ecosystem and constitute a reference architecture from which you can get to multiple sub-architectures and implementations. Being an architect, you'll learn how to better design microservice-led and event-centric architectures in the right way from the early beginning, by showcasing learned lessons, best-practices do's, and don'ts. If you are starting your architecture career, it's the right place to get introduced to concepts and methodologies that you will then grow over time, as you acquire more experience. If you are a developer, but willing to jump into the exciting architecture world, this can also be good reading, however, be warned that some basic architectural understandings and concepts need to be first incorporated before walking through the advanced concepts presented throughout this book. This book requires you to have some minimal background around Docker and Microservices to better understand the more advanced concepts that are being explained.

Security is usually an afterthought when organizations design microservices for cloud systems. Most companies today are exposed to potential security threats, but their responses are often more reactive than proactive. This leads to unnecessarily complicated systems that are hard to implement and even harder to manage and scale. Author Gaurav Raje shows you how to build highly secure systems on AWS without increasing overhead. Ideal for cloud solution architects and software developers with AWS experience, this practical book starts with a high-level architecture and design discussion, then explains how to implement your solution in the cloud while ensuring that the development and operational experience isn't compromised. By leveraging the AWS Shared Responsibility Model, you'll be able to: Develop a modular architecture using microservices that aims to simplify compliance with various regulations in finance, medicine, and legal services Introduce various AWS-based security controls to help protect your microservices from malicious actors Leverage the modularity of the architecture to independently scale security mechanisms on individual microservices Improve the security posture without compromising the autonomy or efficiency of software development teams

Microservices can be a very effective approach for delivering value to your organization and to your customers. If you get them right, microservices help you to move fast by making changes to small parts of your system hundreds of times a day. But if you get them wrong, microservices will just make everything more complicated. In this book, technical engineering leader Sarah Wells provides practical, in-depth advice for moving to microservices. Having built her first microservice architecture in 2013 for the Financial Times, Sarah discusses the approaches you need to take from the start and explains the potential problems most likely to trip you up. You'll also learn how to maintain the architecture as your systems mature while minimizing the time you spend on support and maintenance. With this book, you will: Learn the impact of microservices on software development patterns and practices Identify the organizational changes you need to make to successfully build and operate this architecture Determine the steps you must take before you move to microservices Understand the traps to avoid when you create a microservices architecture—and learn how to recover if you fall into one

Microservices cannot be simply ‘wired up’ with some basic technical knowledge about what constitutes a Microservice Architecture. There is more to a Microservice Architecture than developing isolated and unique services with a blueprint like set of architectural artifacts. Successfully understanding microservices requires a paradigm shift no less radical than moving from a procedural to an object oriented programming language. Microservice Architecture is not just technical but also a new business philosophy rooted in antifragility, employee empowerment, and flattened power structures. This book will take you on an expedition to a yet to be fully explored ‘planet’ with a divergent philosophical underpinning that is completely alien to some technologists. Our voyage of discovery will be traveling through a landscape that is unrecognizable. If it were not for the historical map that explains the origins of this empowering technical perspective most would be disoriented at the outset of the voyage. New conceptualizations are found throughout the book. For instance, a Thought Leader within an Agile/Open Source horizontally defined organizational power structure will be someone who has the business, marketing, technical, inspirational, entrepreneurial, and innovative abilities to help guide an organization's fused business and technical direction. That's right, the large lethargic organization will eventually shift from a hierarchical to a horizontal power structure with the resulting outcome being the elimination of many useless layers of bureaucracy and procedures. We are moving from the age of the monolith both technical and business into a world of nimble employee empowered organizations. Essentially, the new Enterprise Architect or whatever we end up calling this position will be a thought leader for the firm, having the insight across many disciplines to contemplatively drive the company into the 21st Century. In a flattened firm all the previously siloed departments like marketing, finance, leadership, technology, and... are united into cross discipline teams similar to how we utilize Agile in technology. The entire firm is Agilized - not a word yet but maybe it should be. Traveling to this new land of freedom requires that explorers not take any neat and tidy preconceptions with them - come along without any baggage. This book will challenge how you view technology to the core of your being. When you have finished this journey all that you believe and cherish from a technical standpoint will be cast aside.
