Microservices + Orchestration

Write better code to meet the scalability requirements of millions of users by deploying and scaling microservice-based applications.

Course Overview

With the advent of cloud computing resources, computer programmers were freed from the constraints imposed by inefficient corporate data centers. With the new resources came the freedom to establish new and innovative ways to create and deploy software. Thus, the microservices revolution began.

You will build microservice architectures from first principles to establish an in-depth understanding of the current best practices in the industry. Then, you will learn how to containerize, deploy, scale, and manage those microservices to guarantee resilience in a production environment.

How do these two subjects fit together?

Moving from monolithic applications to service-oriented architectures moved the complexity of applications from their implementation to the deployment, monitoring, and management of many individual applications. With the advent of infrastructure as code, developers can own the total application lifecycle. Understanding how to break down the features of an application into individually deployable services, and how to get those services into production in a repeatable and sustainable way, necessitates the comprehensive undertaking of both microservices and the orchestration it takes to make them work together in a production environment.

What more will I learn about microservices?

The term “microservice” has no universal definition. As such, it is important to understand the trade-offs that come with choosing aspects of each service’s internal and external architectures. This class provides you with a robust framework to help you design complex applications through a microservice architecture taking into consideration data responsibility, transactional scope, and strategies to properly test its correctness.

Isn’t orchestration just Docker and Kubernetes?

While Docker and Kubernetes have wide support, they are neither the beginning nor the end of proper application deployment, scaling, and management. You will face and gracefully overcome the challenges of networking and observability. You will get a chance to investigate alternative and complementary ideas and solutions that have strong community and industry support, for example, support for deploying and orchestrating non-containerized applications.

Course Design


This two-fold path begins with exploring strong software design techniques and the fundamentals of orchestration. Using industry-standard design techniques, you’ll start growing your expertise at modeling software systems. You’ll also become familiar with how to isolate an application within a container.

  • Use Domain-Driven Design to structure your approach to software design

  • Learn about different communication paradigms that allow a distributed application’s components to communicate with one another

  • Install and use Docker to codify the foundations of your application infrastructure

With continued application of software design techniques, you’ll be able to determine microservice boundaries for a distributed application. Then, you’ll peer inside a microservice to comprehend the internal workings and communication portals. You’ll use this knowledge to coordinate multiple microservices to run together as an application.

  • Design and build internal and external APIs for microservices

  • Determine the proper communication paradigms and implementations to allow communication with microservices

  • Investigate service discovery using simple orchestration tools

While testing software comes in many forms, the advent of microservices has extended the need for new tools and methods to test the various components’ intercommunication as well as reliability. You’ll work through the challenges of testing microservices using state-of-the-art tools while revisiting design implications for these concerns.

  • Use contract testing to test producers and consumers of messages

  • Understand chaos testing for reliability across a deployed microservice topology

  • Use more complex orchestration tools to manage microservice provisioning and deployment

There are many ways to get your application into production. You’ll use another set of orchestration tools with a different design paradigm to get a microservice-based application into production to support specific deployment use cases.

  • Determine best-fit deployment models for specific functional and non-functional requirements

  • Use alternative orchestration tools to manage microservice provisioning and deployment

Hardening your application for a production environment requires the use of forethought and specific patterns around resource access. You’ll implement resiliency patterns in your application using widely-adopted libraries for a variety of languages.

  • Implement the circuit breaker pattern

  • Implement the bulkhead pattern

  • Implement the sidecar pattern

  • Use a service mesh to automate the security and intercommunication of your microservice-based application

Now, it’s time for the world to see what you can do! You’ll deploy an application using orchestration tools to the major cloud providers. Then, you’ll fine-tune the deployments with specific deployment strategies and discover how they’re supported by the platforms.

  • Perform deployments to the major cloud providers: Amazon AWS, Google Cloud, and Microsoft Azure

  • Implement blue-green, canary, big-bang, and rolling deployments using orchestration tools

Daniel Billotte, Principal Instructor

Daniel Billotte’s career as a software engineer began in the mid 90’s, as the Internet was coming of age. He’s worked at large companies like Netscape, AOL, and Canon, as well as smaller companies and entrepreneurial ventures of his own. He has also worked extensively in the printing industry at every level from cleaning floors to building a globally deployed print-shop workflow tool. He helped start the first coding bootcamp in Phoenix in 2014. Daniel enjoys frontend web, but his passion is for building scalable backend systems that use cool technologies like neural networks. When he isn’t working or playing with his family, he’s riding his mountain bike, learning DSP/audio programming and audio circuit engineering, or breathing new life into an old truck. Daniel has a BS in Computer Science from Arizona State University.
