Microservices Design Patterns
software design pattern is a general reusable solution to a commonly occurring problem within a given context
So, after all your research and reading, you are convinced that you want to implement Microservices. Good! this article assumes you are now ready to swim into the world of Microservices and attain nothing but the top grade in taking it to the next level. But wait, we are not the only ones who are in this ever growing community and expanse of simple, self-contained, polyglot, independently deployable services.
But, rest assured, you are going to face a lot of challenges since you are now entering into the trialling mode of Microservices. Fear not, there are design patterns… even better they are design patterns that fit Microservices architecture style. We will go through some of the design patterns that are practical and applicable to most of this world’s requirements, hence you can apply to your problems or evaluate to fit your needs.
The goal of microservices is to increase the velocity of application releases, by decomposing the application into small autonomous services that can be deployed independently. A microservices architecture also brings some challenges, and these patterns can help mitigate these challenges.
Pattern Map
Instead of listing the patterns and describing them with their pros and cons and doing most of the heavy lifting for you in this article, I have established the Patterns map which will be more useful when it comes to practically assessing them and applying them.
Please exercise caution in not getting these patterns mixed with the 23 GOF Patterns as they are suitable for the actual implementation (coding side) while we here deal with just the way Microservices interact.
For further information, you can always do some google driven development and gain more knowledge about these patterns.
Cloud Design Patterns
There are some notable design patterns that are available to the PaaS / cloud platforms such as AWS and Ms Azure.
For AWS, though there are no specific design patterns for Microservices, this post gives a good overview of the cloud / deployment patterns which is the next natural step in the Microservices journey:
For Ms Azure, this post gives a good overview of the patterns:
Resources
Finally
As hinted above, the next step would be to look at the Microservices deployment patterns and get accustomed to them. This is an interesting area of exploration and even better with containers that fit into this architectural style. Happy Microservicing!
