Microservices and Containers

978-0-13-459838-3 (ISBN)
Thanks to the tech sector’s latest game-changing innovations—the Internet of Things (IoT), software-enabled networking, and software as a service (SaaS), to name a few—there is now a seemingly insatiable demand for platforms and architectures that can improve the process of application development and deployment.
In Microservices and Containers, longtime systems architect and engineering team leader Parminder Kocher analyzes two of the hottest new technology trends: microservices and containers. Together, as Kocher demonstrates, microservices and Docker containers can bring unprecedented agility and scalability to application development and deployment, especially in large, complex projects where speed is crucial but small errors can be disastrous.
Learn how to leverage microservices and Docker to drive modular architectural design, on-demand scalability, application performance and reliability, time-to-market, code reuse, and exponential improvements in DevOps effectiveness. Kocher offers detailed guidance and a complete roadmap for transitioning from monolithic architectures, as well as an in-depth case study that walks the reader through the migration of an enterprise-class SOA system.
Understand how microservices enable you to organize applications into standalone components that are easier to manage, update, and scale
Decide whether microservices and containers are worth your investment, and manage the organizational learning curve associated with them
Apply best practices for interprocess communication among microservices
Migrate monolithic systems in an orderly fashion
Understand Docker containers, installation, and interfaces
Network, orchestrate, and manage Docker containers effectively
Use Docker to maximize scalability in microservices-based applications
Apply your learning with an in-depth, hands-on case study
Whether you are a software architect/developer or systems professional looking to move on from older approaches or a manager trying to maximize the business value of these technologies, Microservices and Containers will be an invaluable addition to your library.
