Microservices Architecture is a great way to structure your single monolithic codebases. It gives an opportunity to scale the architecture, giving you complete portability of an application. But before going through all the benefits of microservices, it is important that we understand the key points of Microservices Architecture in order to get the maximum value out of the entire structure.
Best practices to include while implementing Microservices Architecture
1) Why Microservices Architecture?
First, identify the need whether micro services architecture for your cloud application development is going to be really beneficial or not. The biggest advantage of microservices is the way it disintegrates data and operations. This distributed system will help to partition all your data into different services. This gives an option to scale the system along with the data that needs to be prescribed independently so that the service logic is separate. You will need to identify whether such separation of data, components and services which brings scalability is really required for your product, use case or a business application on cloud.
Each unit in the application runs with its own runtime and different processing threads giving it a better elasticity than the monolithic architecture. If you need such elasticity and scale, you will have to plan your resources, separating data; teams separated, leading to efficient ways of managing each service independently irrespective of resources.
3) Define the kind of microservices
The success of microservices architecture is mainly on how you design, define and architect this system. Before implementing it is important to clearly understand your business function, your use case, your modules,, services, and to understand how these different modules will interchange and exchange data into each other. A clarity on your business function is important to define the architecture that subsides in the system with fragmentation. So, remember to recognize your business functionality far ahead to build optimal microservice architecture.
4) Recognizing Scalability of your Structure
Scalability being the major aspect of microservices, it allows an application to be broken down into units and then concurrently being processed in parallel. Thereafter, increasing the overall efficiency of the application. So, while inducing scalability identify these aspects in your system – resource bottlenecks for read and write traffic.
Start by knowing and understanding the nature of growth your system would have. Assess this on predetermined data or put your assumptions to design a system with a performance benchmark to understand it’s qualitative growth scale. Thereafter is the capacity planning, this is where quantitative and qualitative growth comes into play. Next is dependency scaling; You need to understand the interdependent scenarios which could lead to bottlenecks for fetching and writing data into your databases. This is where a well defined decoupled module would help to bring that scale for your system.
5) Ensuring Cost Vs Benefit
All in all, Microservices Architecture transformation will lead to an independent management of services which will give your application an agility that will facilitate continuous delivery and faster time to market. Of course, initially when you are building with a microservices architecture, it will take time and cost of it will increase but you build your systems with a mindset of modernization and to sustain for the future for at least for 5 years. Implementing the microservice architecture isn’t only a technical decision this kind of transformation also requires a buy-in from the stakeholders into account to ensure that any system that you are building is able to sustain. So, before your monolithic architecture is transformed into microservices or needs to be modernized we need to understand what are the benefits it’s going to bring for the system in the longer run.
6) A good set of DevOps toolkit
To get an optimal value out of your new architecture you need to automate your services testing, build and deploy management. Therefore it is important to set up a good set of DevOps process as you will find it faster to release your application.
7) A single entry point
Implement an API Gateway which is a single entry point for all the requests of your client. Since in microservices architecture, each service is managed independently, from its authentication, business logic and database, we need a common gateway to interact with different services of the system. This helps in distributing your client requests separately for each service. Also, it gives an advantage to host and request each service of your application differently. The communication protocol between your product and services should be as simple as possible and it would be in charge of transmitting the data without changing it. Microservice architectures have the capability to keep data or resources as straightforward as possible to avoid tight coupling of the elements. In some opportunities you might find yourself using an event driven architecture with asynchronous message wise communications.
8) Keep in mind the challenges
We know microservices can provide you great benefits from decoupling, fragmentation, flexibility to scalability. But you can come across various challenges when you work on it as a whole system. As your system is divided into distributed systems it can now have multiple bottleneck points, so you need to take in account the multiple bottlenecks points. Along with it you also need to understand network hops it may have due to fragmented services. Hence the question is whether my application really needs a microservices architecture.
9) Reduce Deployment Friction
Microservices can sustainably support continuous delivery as you have an increasing number of services that need to be deployed multiple times a day. So it is critical that you go with continuous delivery to minimize the risks of release failure, as well as ensuring that your resources are focused on building and running the application rather than being stuck at the deployment stage.
The biggest commercial Advantage that Microservice Architecture provides:
The biggest advantage is that microservices give an opportunity to scale, to manage, to integrate independently which helps to bring agility in your application. Also, with decoupling, it gives you a possibility to scale each service independently. We would highly recommend Micro services architecture for applications which have third party API integrations, Internal multiple Business logic scenarios, Multiple product offerings where there is a way to scale, manage and integrate each service module independently.
