Microservice Patterns and Best Practices

The Microservice Tools

Some issues are always questionable or controversial when it comes to choosing a microservice stack. Much is discussed regarding the performance, practicality, cost, and scalability. Most of what is discussed is background views; many of these are valid opinions and many others not so much.

Obviously, the history of the development team should be considered in any technical decisions regarding the stack and implementation. However, at times, it is necessary to leave some comfort zones behind to develop a product. A comfort zone can be a programming language, a protocol, a framework, or a database, and they can limit a developer's ability to move at speed. The developed application then becomes more and more scalable.

In this chapter, you will be working on points that should be examined for internal discussions and development teams. In the end...

Programming languages

Discussing programming languages is something that can be controversial, primarily because many developers tackle programming languages in a great hurry. However, programming languages should be seen as what they really are, a working tool. Every tool has a specific purpose and programming languages are no different.

It is just an analysis focused on our business, the news portal, which we will use to get to the point of how to select a language.

A big plus point for microservices is the heterogeneity of applications. In other words, it is not necessary to think of a single stack to apply to all business areas. We can thus define each microservice stack that applies, including when it comes to a programming language.

Basically, any programming language that meets the internet can be used in microservices. The difference is due to the requirements and domain...

Microservice frameworks

When dealing with frameworks, we have to think that because of the technological diversity of our frameworks, we will have at least three frameworks instead of one to keep our ecosystem.

Of course, we could have kept all microservices in the same stack. However, searching for the best overall performance for each domain, we opted for a more plural stack.

Obviously, at first, the impression is that the complexity will be higher than expected. But this type of complexity is matched by the performance most suitable for each case.

Basically, we chose three different programming languages to use on our news portal. Python, Go, and C# are those languages. It is time to think about which frameworks we will use for each of these languages, thus taking another step in shaping our development stack for each microservice.

...

Binary communication – direct communication between services

Much is discussed about microservices communication; topics such as protocols, layers, types, and package sizes are widely discussed when it comes to the subject.

The point is that communication between microservices is the most critical topic for project success. It is very clear that the amount of positive factors increases with microservices architecture, but how to make the communication that does not encumber the performance of a product to the end user is the key point.

It does not help that all the practicalities of developing and deploying the product do not scale or the end user experience is compromised.

There is a lot of literature and study material on the subject, but the challenge still remains. And oddly enough, even with all the available material, making mistakes in this part of the project...

Message broker – Async communication between services

In the previous topic, we talked about synchronous communication between microservices using binary and alternatives to REST. This topic will deal with the communication between microservices using message broker, that is, a messaging system with a physical element, a communication layer, and a message bus.

With messaging systems, it is impossible to reproduce the Death Star. The design of the Death Star in a more robust application would be something like the following:

The diagram of a messaging system is totally different, similar to the one shown in the following:

The message bus can be used for both synchronous and asynchronous communication, but certainly, the major point of emphasis of the message bus is in asynchronous communication.

You may wonder, if the messaging diagram is simpler and you can use this type...

Description

Microservices are a hot trend in the development world right now. Many enterprises have adopted this approach to achieve agility and the continuous delivery of applications to gain a competitive advantage. This book will take you through different design patterns at different stages of the microservice application development along with their best practices. Microservice Patterns and Best Practices starts with the learning of microservices key concepts and showing how to make the right choices while designing microservices. You will then move onto internal microservices application patterns, such as caching strategy, asynchronism, CQRS and event sourcing, circuit breaker, and bulkheads. As you progress, you'll learn the design patterns of microservices. The book will guide you on where to use the perfect design pattern at the application development stage and how to break monolithic application into microservices. You will also be taken through the best practices and patterns involved while testing, securing, and deploying your microservice application. At the end of the book, you will easily be able to create interoperable microservices, which are testable and prepared for optimum performance.

Who is this book for?

I really like the authors writing style and approach to explain this complex topics. He's doesn't try to fly high, looking at the topics from far away and pretending that with theoretical knowledge is enough on Software Engineering. Instead, he takes the time to walk every step of the software design and architecture process, and gives you the details you'll need when you face common problems. Even more, he gives you common sense-based reasons to use the patterns he proposes and why the 'best practices' are considered such.I had previous experience on Software Engineering, so I can't speak from the point of view of someone that is new to this topics. However, I didn't have any experience with Microservices and when I read the book all the topics were correctly presented for my level of knowledge.

It's really a complete book covering integration and design patterns, a clear teaching and understanding about microservices and mainly dealing with high transactionals volumes . A lot of tips and warnings when implementing a solution microservices based. When talking about design patternsis possible "see" the experience and the care with the detalis of the author how to better define a simple to complex system or ecosystem. If you are a system architect, read it, if not, read! And it goes beyond , giving us an approach about tools, techniques, languages, etc., is awesome!

As someone who has worked with microservices before, I can tell this book is a must-have for anyone who's starting with microservices, or wants to switch from a monolithic application, or simply wants to know more about microservices and the right way to implement them. As the author states in the book, when microservices are not correctly implemented, they can be a nightmare, which is why it's so important to follow the right patterns and apply the correct design.The book is really easy to read and it goes straight to the point, very practical and useful. But at the same time, it covers every step of the way needed for a good and robust architecture, starting from a very simple example.

As a beginner in the microservices world, I wanted to deepen my knowledge so that I could apply it in the company I work for. After reading this book, I acquired a critical thought that allowed me to spot some warnings and enhancements that could be applied on the way we build and manage microservices. Really good examples, I liked the way the author explains.

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
