Microservice Architecture

Microservice Architecture

An introduction of the main concepts of microservice architecture (MSA). We focus on the notion of microservice architecture in connection with “traditional” methods for building a system. Microservice architecture patterns are discussed as well as MSA deployment issues and methods for ensuring required qualities.

Description


Microservice architecture (MSA) has recently become one of the most popular architectural approaches, because it provides numerous benefits at different stages of the product life cycle. In particular, MSA allows you to improve reaction time when it comes to business requirements.

Yet, in the process of MSA system development, architects face many challenges which often force those who are new to this field to roll back. Some of them include:

  • Errors in decomposition may make the development much more difficult
  • Performance decreases due to serious network delays
  • Distributed data storage prevents us from using transactional consistency
  • A large number of components communicating over the network reduce the system’s reliability
  • It gets difficult to ensure security

Not to mention that testing and maintenance of a distributed system requires additional efforts. This course will help you understand the advantages and disadvantages of MSA so you can decide on the feasibility of using MSA depending on business needs and team capabilities.

We cover the major challenges related to implementing microservice architecture and provide you with strategies, mechanisms, and patterns to solve them. We’ll also be looking at the most popular tools (such as Kubernetes, Istio, Histryx, Kibana, and many others) used in Microservice architecture.
