Deconstruct Your Monolithic System With Intertech’s Microservices Assessment, Migration, Integration & Quality Assurance Services!
As applications get more complex, they can get unruly. A wise alternative is to consider a Microservices software development approach.
Microservices is a buzz word that means so many different things to so many different organizations. Let’s evaluate your needs together and then transform a cumbersome system into an agile module-based system that delivers exactly what it means to you!
What Are Microservices?
What Are Microservices?
What Are The Benefits?
When your applications are connected but working independently from one another, your development teams are more efficient. You also gain the agility to scale a service without affecting the entire monolithic system. Maintainability and ease of deployment are two other benefits. You will see faster development with a smaller codebase for each Microservice (in most cases), making it easier to unit test, maintain, and deploy. Lastly, failure isolation is possible by reducing the effect to a single module rather than the entire critical application. In this way, you can remain operational. The benefits are real, but so are the challenges…
What Are The Challenges?
Key Microservices Best Practices
- Consider Domain Driven Design – Domain Driven design, in its simplest form is understanding what the software is all about in relation to the industry. It is a methodology for the development of breaking complex systems into focused modules that relate to task and activities so you can map events and data effectively. It is important to have clear communication between business experts that understand the process and experts that can implement the solution (Architects/Developers). This step allows you to break the complex application into your modules.
- Database Sharing – Yes or No – Database sharing is an important decision and should be determined next. If you decide to share the database you are assuring a strong coupling of the Microservices. However, if you do this you are in a way defeating the purpose of going to Microservices and it’s ability to easily decouple from the mass. This is something to discuss in detail and the idea of private tables or separate databases should be considered.
- Make Sure Your Front End Is Also A Microservice – Basically, if you are breaking up the backend, you should do the same with the front end. Micofrontends maintain the modularity when needed in the future and will be rewarded.
- Agile Delivery – It is important to deploy Microservices independently. Whether you are using a CI/CD (Continuous Integration/Continuous Delivery), DevOps, or Agile development methodology, they are all fast and are based in agility.
- Tracing and Observability Is Key – Monitoring one single software system, even if large, is much easier than keeping track of a multitude of modules. For this reason it is important to consider how you will log and trace latency in the system and identify the culprit. For these tasks there are resources available in the market that should be vetted prior to beginning so you are aware of all the costs associated with going to Microservices.
- Use A Proven Language – There are many frameworks, languages, and tools to implement Microservices, but staying with Java, C++, Node.js, .NET (&ASP.NET), Golang (Go), and Python may be your best bet. For example, with Java there are several frameworks that can be used to develop your Microservices Architecture, to include Spring Boot, Restlet, & Spark. .NET is another framework that can make the transition easier.
No matter which language you decide to use, the future of Microservices is leading us closer to serverless architecture and greater cost savings and reliability. With more complexity required from your applications it is crucial to set your system up so it can be managed effectively without taking down the entire system when an issue arises.
Microservices Assessment
Before we begin, we always do a complete assessment of your enterprise IT system(s).
First, we detail your current monolithic applications and legacy systems and help determine break-points that will, in the end, define your Microservices modules. The last portion of the assessment stage encompasses an evaluation of your strategic roadmap to outline how together we can best reach your long-term and short-term goals based on internal assets and best practices, so you have a clear picture of how your teams should be structured for success.
Microservices Architecture – Monolithic to Modular
Once a detailed assessment has been completed, your migration from a monolithic system to a lightweight collection of autonomous services begins.
This is known as the Microservices architecture. As the Microservices are identified and decoupled, we’ll help you decompose applications by business capabilities, subdomain, & services. This is also the time to refactor outdated applications or services that do not have natural separation points but should be seperated into more agile modules.
Integration, Testing, and Deployment
The great thing about Microservices is that it enables your development teams to work independently and if challenges arise, they do not impact the rest of the project.
When it comes to testing, however, there are multiple facets to consider. For example, because Microservices rely more on over-the-wire networking, connections and all contracts between the microservices must be considered, along with interaction between the various containers. It is a big step forward but when you realize the benefits you will understand the amazing value.
