Microservices at Silicon Valley Code Camp

Silicon Valley Code Camp is one of my favorite local conferences. At Silicon Valley Code Camp 2018, I gave two talks and took part in one panel. The video for one of talks and the panel should be available soon. In the meantime here are the slides for the talks.

Microservices: Decomposing Applications for Testability and Deployability

Successful applications have a habit of growing. What’s more, the rate of growth increases over time because the development team typically gets larger. Eventually, the application will become extremely large and the organization ends up in monolithic hell. All aspects of development, testing and deployment are slow and painful. It’s impossible for the developers to keep up with the demands of the business. And, to make matters worse the application uses a technology stack that is increasingly obsolete. The way to escape monolithic hell is to migrate to the microservice architecture.

In this talk, you will learn about the essential characteristics of microservices. I describe the benefits and drawbacks of the microservice architecture and when it makes sense to use it. You will learn about the design problems you will encounter when using microservices. I describe how to solve this problems by applying the microservices pattern language. You will learn how the microservice architecture accelerates the delivery of large, complex applications.

Developing Asynchronous, Message-Driven Microservices

The microservice architecture functionally decomposes an application into a set of services. Each service has its own private database that’s only accessible indirectly through the services API. Consequently, implementing queries and transactions that span multiple services is challenging.

In this presentation, you will learn how to solve these distributed data management challenges using asynchronous messaging. I describe how to implement transactions using sagas, which are sequences of local transactions, coordinated using messages. You will learn how to implement queries using Command Query Responsibility Segregation (CQRS), which uses events to maintain replicas. I describe the key role that messaging plays a microservice architecture.
