What is a Microservice Architecture?
Microservice architecture is an architectural style that structures an application as a collection of software services that are. Highly maintainable and testable. Loosely coupled. Independently deployable.
All of this is run within a single process, and if our Lego store becomes very popular and we want to expand the business, we will have to add more Lego blocks in the same unit… and in the case of the online store, add more servers in order to scale it out.
So, every change (even minor changes) in our Lego store (physical or online) can be slow or tedious as it affects the entire software system. In the case of Jeff’s store, a modification can require the removal or addition of multiple Lego blocks, affecting the entire software structure. In the monolithic online store, a modification made to a small section of code might require building and deploying an entirely new version of software. So, scaling specific functions or components of the application, also means you have to scale the entire system.
2. One Cloud to Rule Microservices: AWS
If you’re not building your own server, then you’re probably #teamMicroservicesAWS. Amazon Web Services is the cloud provider for microservices with almost 50% out of other cloud providers. What’s more, AWS Lambda is also killing it in serverless technologies.
AWS pretty much rule them all when it comes to cloud providers and serverless solutions, however, it’s not yet time to put a ring on it and call it the number #1. With bare-metal servers still doing pretty well, Amazon Web Services are far from a monopoly on microservices. Still Confused? know more with a free consultation from Terkwaz Business Solutions.
3. Disadvantages of Microservices?
Software Microservices may be a hot trend, but the architecture does have drawbacks. In general, the main negative of software microservices is the complexity that any distributed system has.
Here’s a list of some potential pain areas and other cons associated with software microservices designs:
- Communication between software services is complex: Since everything is now an independent service, you have to carefully handle requests traveling between your modules. In one such scenario, developers may be forced to write extra code to avoid disruption. Over time, complications will arise when remote calls experience latency.
- More services equals more resources: Multiple databases and transaction management can be painful.
- Global testing is difficult: Testing a microservices-based application can be cumbersome. In a monolithic approach, we would just need to launch our WAR on an application server and ensure its connectivity with the underlying database. With software microservices, each dependent software service needs to be confirmed before software testing can occur.
- Debugging problems can be harder: Each software service has its own set of logs to go through. Log, logs, and more logs.
- Deployment challengers: The product may need coordination among multiple software services, which may not be as straightforward as deploying a WAR in a container.
- Large vs small product companies: Microservices Architecture are great for large companies, but can be slower to implement and too complicated for small companies who need to create and iterate quickly, and don’t want to get bogged down in complex orchestration.
4. Continuous Integration
Continuous Integration (CI) is a development practice where developers integrate code into a shared repository frequently, preferably several times a day. Each integration can then be verified by an automated build and automated software tests. While automated testing is not strictly part of CI it is typically implied.

6. “Microservices” killed?
I thought I’d analyse the possibilities as to why one wouldn’t want to use the microservices pattern in their mobile application architecture. It’s not like developers are migrating from monoliths to microservices, just because everyone else is doing it. Like any other architectural decision, there are several factors that need to be taken into consideration before making the switch. So here’s what Terkwaz Business Solutions thought were some reasons why developers are sticking to monoliths.
Nowadays using microservices has changed software development for good. More and more developers and tech leaders know what microservices architecture benefits are and how to properly handle it even in the most complex software projects. One thing is for sure microservices architecture are here to stay. Follow Us on Terkwaz’s Business Solutions LinkedIn page to find more useful tips on the business solutions.
