What is a Microservices architecture?

Building enterprise applications with the help of a monolithic approach has become fierce as apps get more extensive and more complicated. So programmers or developers are switching to a Microservices software development architecture, in which applications include loosely coupled services. This makes them simpler to build, and more importantly much easier to explore and scale.

Developing a high-performance Microservices architecture with RavStack

There is more to building a Microservices architecture than merely dividing a monolithic software application into some smaller modules. To fully realize the advantages of this modern app-development methodology, it’s crucial to optimize the data layer.

You need to consider how your data is handled, develop interservice communication, and synchronize data across geographies and availability zones.

RavStack helps you understand the fundamentals of Microservices architecture. With the help of our expert team, you can design interservice communications while building new services.

Best practices on switching to a Microservice architecture

Switching to a Microservice architecture looks simple, but experts and professionals tend to underestimate the toughness of the project and make huge mistakes.

Before switching to Microservices, or starting one from scratch, you need to carefully put an eye on the technological and organizational challenges that will arise.

Creating separation between Microservices enables them to be modified as quickly as you need them to be. This generally requires separation at various levels:

Runtime processes

This is quite usual, and one that’s commonly adopted rapidly. Where before you had a single process, now you have various. The primary goal here is adopting some form of distributed computing, which is challenging to do efficiently. This may lead you to take containerisation, service meshes, event architectures, different HTTP management approaches, and circuit breakers.

Team

Separating teams, to provide you autonomy, means you are dividing your human-to-human communication. This tends to lead to knowledge silos and task duplication (working out of the optionality vs resource efficiency choice).

Data

Adopting a distributed computing approach like Microservices can affect your data. You have divided your data in some form, and so you need to re-integrate it at the system level to provide the impression of a system.

This serves you with some compelling potential advantages regarding scaling, but it also requires much more effort than a simple monolithic approach to data architecture.

Advantages and disadvantages of a Microservice architecture

You have small modules you can analyse to see what is the need of each module. It enables you to scale different parts of your software or application separately.

Benefits

  • Easier maintainability
  • Deploying and configuring without many mistakes
  • Problem isolation
  • Higher understandability
  • Usage of various programming languages

Disadvantages

  • Deployment and interoperability
  • Making components work together
  • Challenging to do integration tests
  • Requires extra effort in communication
  • Complexity
  • Difficult to monitor the entire system
  • Architecture has to be well-structured through from the starting.

What technologies should you select for a specific Microservice?

Spending so much time on choosing the best technology isn’t good at all since there are few differences.

The importance of selecting technology is too much. If the running costs are essential, then it can be acceptable, but it doesn’t matter that much for us.

Choosing the appropriate technology isn’t just a technological query but also a hiring decision. If you select a Microservice architecture with 10 different developing languages, you need to make sure your experts can handle that.

When selecting a technology for a Microservice, it’s essential to consider the following aspects:

Maintainability

Scalability

Fault-tolerance

Price of architecture

Ease of deployment

Some examples of frameworks/technologies:-

AWS services

Scrapy for web crawling

NLTK + Tensorflow

Celery + RabbitMQ

Key takeaways

Do not worry so much about choosing the right technology. Take an iterative, experimental process instead.

Every Microservice architecture is different; the selected technology should be matched with the system’s requirements.

Keep in mind that too many various technologies make hiring more difficult.

Why choose RavStack?

There is no one best method to choose the right technology for a microservice. Every technology-related decision is influenced by your professionals’ current knowledge and also by the organization’s future hiring plans.

In some cases, choosing a technology for a Microservice is more of a hiring decision, and it’s up to you what kind of expert team you want to hire in the future.

RavStack provides an excellent database for Microservices. Our expert team of developers delivers high performance with low latency and supports multi-tenancy.

We offer open-source solutions with high availability and durability for developing high performing event stores for trading Microservice messages.
