This Preview Edition of Building Microservices, Chapters 1, 4, and 11, is a work in progress. Newman. Building Microservices by Sam Newman. Copyright. Building Microservices takes a holistic view of the topics that system architects and administrators must consider when building, managing, and. Building Microservices is published by O'Reilly and available now. The book is aimed at practioners and architects and will help you understand what.
The Good Newman takes a holistic approach, analyzes the topic from lots of angles. It isn't a dry read but the a Microservices are a relatively new trend in computer science, coined around It isn't a dry read but the author introduces a couple of real-life experiences leading to an enjoyable read.
I found a couple of gems embedded in the text that I didn't know about, like references to Nagios, Hexagonal Architectures or Holistic Software Development, which I plan to read about later on.
The book is quite short with only pages and will take only a couple of evenings to dig through. Each chapter ends with a nice summary. The Bad Given its size and the broad range of topics, it doesn't come as a surprise that each topic doesn't get a lot of screentime, leading to a very shallow discussion.
This comes in handy, if you only want to get hints what could be thought about. In the end, the coverage isn't very helpful.
It is an egocentric text, stemming from thoughts of the author alone, it doesn't introduce community's knowledge or give any hints to further readings in this specific area. In May , the same group decided on "microservices" as the most appropriate name.
On slide 4 of the conference presentation, he states that " Software components are Micro-Web-Services". Complex service-assemblies are abstracted behind simple URI interfaces.
Any service, at any granularity, can be exposed.
It can contain information, code or the results of computations so that a service can be either a consumer or producer in a symmetrical and evolving architecture. Microservices is a specialization of an implementation approach for service-oriented architectures SOA used to build flexible, independently deployable software systems.
There is no consensus or litmus test for this, as the right answer depends on the business and organizational context. Amazon 's policy is that the team implementing a microservice should be small enough that they can be fed by two pizzas.
But the key decision hinges around how "clean" the service boundary can be. On the opposite side of the spectrum, it is considered a bad practice to make the service too small, as then the runtime overhead and the operational complexity can overwhelm the benefits of the approach.
When things get too fine-grained, alternative approaches must be considered - such as packaging the function as a library, or by placing the function into other microservices. When effective, the gap between architecting a project and deploying it can be minimized.
Therefore the most important technology choices are the way microservices communicate with each other synchronous, asynchronous, UI integration and the protocols used for the communication REST, messaging, In a traditional system most technology choices like the programming language impact the whole systems. Therefore the approach for choosing technologies is quite different.
The service instance and sidecar proxy share a container, and the containers are managed by a container orchestration tool such as Kubernetes. The service proxies are responsible for communication with other service instances and can support capabilities such as service instance discovery, load balancing, authentication and authorization, secure communications, and others.
In a service mesh, the service instances and their sidecar proxies are said to make up the data plane, which includes not only data management but also request processing and response.
The service mesh also includes a control plane for managing the interaction between services, mediated by their sidecar proxies. The microservices approach is subject to criticism for a number of issues: Services form information barriers.
However, lack of this technology causes awkward dances which have to be implemented by all the transaction participants in order to maintain data consistency.
Cognitive load[ edit ] The architecture introduces additional complexity and new problems to deal with, such as network latency , message formats , load balancing and fault tolerance. The complexity of a monolithic application doesn't disappear if it gets re-implemented as a set of microservice applications.
Some of the complexity gets translated into operational complexity. Also, an application made up of any number of microservices has a larger number of interface points to access its respective ecosystem , which increases the architectural complexity. A comparison of platforms[ edit ] Prior to Kubernetes and its ecosystem of tools being developed, implementing a microservice architecture was hard because of the lack of popular frameworks. There are many concerns see table below that any microservice architecture needs to address.
Netflix developed a microservice framework to support their internal applications, and then open-sourced  many portions of that framework. Many of these tools have been popularized via the Spring Framework — they have been re-implemented as Spring-based tools under the umbrella of the Spring Cloud  project.
The table below shows a comparison of an implementing feature from the Kubernetes ecosystem with an equivalent from the Spring Cloud world.
Spring Config Server, Netflix Archaius both support a Git-repository--based location for configuration. Archaius supports data typing of configuration.
