Should I Consider A Microservices Architecture?

Microservices – What Is It?

Software must be nimble! Microservices addresses this with a scalable, flexible architecture (i.e., multiple codebases work together) that is fast!

 

If it isn’t quick to deploy, easy to maintain, and scale as needed without affecting the entire system, you limit your ability to compete in this rapidly changing world. Microservices give you all of this and more.

Like an electrical panel powering your home, microservices become the individual circuit breakers that prevent the entire system from breaking down when there is an issue or failure. With microservice architecture, you gain the flexibility to plug in new “ideas” or update pieces of the puzzle without affecting the whole system.

In other words, Microservices separate your monolithic applications into small, agile modules.

Advantages of Microservices Architecture.

 

    • Quicker Launches & Feature Upgrades Changing a monolithic system by adding or subtracting from it can affect the entire system and cause delays. If you are working on a Microservices system, you can do the work, turn it on and turn it off for testing or deployment, and expand on it while the rest of the system is still functioning as it always has.

    • Multiple Codebases Because everything is independent, you can select the best codebase based on the requirements and select the right team for the project, internal or external, and let them do their work independently, without worrying about the rest of the system. Microservices allow web, mobile, and desktop applications to work together like never before.

    • Isolation For complex platforms, having the ability to locate and isolate issues within a single software module rather than searching the entire monolithic system can save in multiple ways. The ability to recover from failures quickly or roll back a buggy update and take care of it without affecting the rest of the system is just one.

    • Smaller Agile Teams & More Accountability Microservices allows you to become more agile with your development teams, giving you more flexibility with outsourcing partners, as well as more accountability with internal and external resources. No longer can anyone hide from their responsibilities.

    • Automated Monitoring With complexity comes the challenge of monitoring the entire system. This is where you can build automated testing scripts to ensure that individual applications are always doing what they are supposed to do.

    • Growth Is At The Core One of the greatest benefits for companies that like to place themselves ahead of the competition, Microservices allows you to develop for the web or a mobile device, or even a desktop app, and connect them. This format results in more control over the user interface while collecting data from every corner of your business. Add the feature of data formatting for machine learning and automation and everything you do suddenly becomes more valuable.

 

Disadvantages of Microservices Architecture.

 

    • More Moving Parts Microservices will require more planning to ensure a smooth transition. However, with a team that has done this before you can identify low-hanging fruit that can be decoupled easily and then create a hierarchy that works with the available project team, expectations, and goals.

    • Automated Monitoring This was mentioned above as an advantage, but there is also an initial disadvantage. Once in place and when written correctly, automation is always a plus. However, at the beginning, and when not precisely scripted, this can add complexity and, before launch, difficulty maintaining the system properly.

    • Third-Party Applications With every third-party application (SaaS), you have the potential for an issue that is out of your control. The benefit of Microservices is that you can unplug it and isolate it if there is an issue while also having the option to bring the application back online once a solution has been implemented.

    • Pushback With any change, there will always be pushback. Fear of change is typically the big one, but it can be addressed early and taken care of before it becomes an issue with proper leadership.

 

Microservices architecture is about identifying the various parts of a software system, converting them, and expanding new requirements into autonomous modules that can be deployed and modified independently of the rest of the system. However, it is essential to plan accordingly, or complexity can overtake your goals.

Key Microservices Best Practices

      • Consider Domain Driven Design — Domain-Driven design, in its simplest form, is understanding what the software is all about concerning the industry. It is a methodology for breaking complex systems into focused modules that relate to tasks and various activities so you can map events and data effectively. It is vital 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 may be defeating the purpose of going to Microservices and its ability to decouple from the mass easily. Make sure to discuss this in detail before proceeding, along with the concept of private tables or separate databases.
      •  

      • Make Sure Your Front End Is Also A Microservice — If you are breaking up the backend, you should do the same with the front end. Micro frontends maintain modularity when needed in the future, and you will be rewarded.
      •  

      • Agile Delivery — It is crucial to deploy Microservices independently and with agility. Whether you are using a CI/CD (Continuous Integration/Continuous Delivery), DevOps, or Agile development methodology, they are all fast and are based on this principle.
      •  

      • Tracing and Observability Is Key — Monitoring one single software system, even if extensive, is much easier than keeping track of many modules. For this reason, it is important to consider how you will log and trace latency in the system and identify the culprit. There are resources available in the market for these tasks that should be vetted prior to beginning. It’s always a good idea to be aware of all the costs associated with going to Microservices before beginning.
      •  

      • 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, several frameworks can be used to develop your Microservices Architecture, including 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 more significant cost savings and reliability. However, with more complexity comes more importance on doing it right from the beginning.

Where Should You Start?

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. Next, we evaluate 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. And finally, we outline our team based on the above to ensure all the right roles are filled to accomplish the project correctly.

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 will 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 separated 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.

However, when it comes to testing, 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 the interaction between the various containers. It is a big step forward, but you will understand the amazing value when you realize the benefits.
