Why Microservices – More Monolithic Clients Are Transitioning

Why Should Your Company Use a Microservices Architecture?

Many organizations adopting microservices decide that monolithic, all-in-one software environments no longer fit the way they work. Over time, these legacy systems can become difficult and expensive to manage. They sometimes provide functionality hardly anybody uses. It might take staggering resources to adapt them to enable the rapid innovation and digital processes that companies want to realize. Neither are all monoliths able to draw on the computing power and scalability of the cloud.

Why More Monolithic Clients Are Transitioning to Microservices

Microservices can provide a huge return for your innovation efforts and yield desirable business outcomes rapidly. You can get your microservices initiative going in the right direction by making sound decisions and taking one well-planned step at a time, starting with the needed infrastructures and processes.

To transition away from monolithic legacy software, organizations create and implement microservices to gain just the functionality they need and evolve it in the cloud. That means conceptually and technically decoupling large application suites into distinct services, which can be created, tested, deployed, and provisioned to users one at a time. See our microservices service page for a thorough explanation of creating and deploying microservices.

Advantages of using a microservices architecture:

  • Speed: Microservices can help you get software functionality to internal and external customers faster, generating revenue, and improving productivity. The modular approach of microservices replaces the application suite with a portfolio of components that can be built by different teams working in a concerted manner. Microservices can be prioritized by business requirements and truly begin showing their value when you perform continuous integration and continuous deployment (CI/CD) to keep your code aligned and connected, and get new capabilities to customers or users quickly. By adopting a microservices approach, an organization may find it easier to respond to fast-changing business needs and deliver the best possible customer and user experiences.
  • Scale: Monolithic applications may scale effectively to increasing numbers of transactions, but tend to become problematic when they cannot accommodate growing data volumes with the same ease. Development efforts may then find it hard to keep up. You probably need to create a very large team that can be difficult to coordinate and manage, whereas specialized, well-orchestrated teams in a microservices practice can be faster and more efficient. The flexibility of using different development tools and underlying technologies in monolithic environments tends to be limited because it is often too difficult or risky to change them.
  • Flexibility: Microservices are polyglot or language-agnostic, meaning you have a choice of which development language you use. Sometimes, working with multiple languages can make it possible to realize functionality in a more powerful or efficient manner.

Why Microservices? Microservices can have significant advantages over monolithic applications. However, it takes a strategic effort and the right company processes and culture to decouple application functions, prioritize them, and incorporate them into a framework that can help you structure and maintain the creative process that ensues.

Thanks to high-profile adopters like Amazon, Netflix, and PayPal, microservices have long been trending upward. However, as more organizations embrace DevOps, cloud computing, and containerization, microservices are becoming the preferred architecture for building enterprise-grade applications.

What Are Microservices Used For?

The short answer is, microservices are used to address the issues associated with monolithic applications, including:

  • A lack of flexibility
  • Interdependency
  • Slow development pace
  • Difficulty scaling

Developers are increasingly looking toward microservices to build larger, more complex software applications that are easier to manage as a collection of small services that work together.

Because services are small in scope and feature a modular design made up of several loosely-coupled components, organizations gain increased fault tolerance and faster deployment times, which in turn enables continuous improvements and frequent feature releases.

With monolithic applications, you’re looking at large scale releases any time you want to, say, update the payments feature or introduce a new reporting tool. What this means is, you might be looking at a months-long process where you’re tracking requirements, then developing, deploying, and testing one long block of code all at once.

With microservices, updates can happen every week or few days, not every quarter or every six months. The benefit here is that you’ll be able to generate revenue from your development investment in short order.

Microservices allow you to prepare for evolving business and market requirements, providing the flexibility to add new capabilities and scale up or down in response to changing demands. Ultimately, deciding whether microservices is your best option depends on several factors. From culture to use cases, there are some scenarios where moving toward microservices is the best solution.

For example, if you have to rewrite legacy applications in a different programming language or using a whole new tech stack to match current business requirements, breaking up the monolith can help you avoid this problem in the future. If you need to reuse modules across multiple channels or you’re building an application that requires frequent updates and fast deployments, microservices will make life easier for your team long-term.

It’s worth noting that, over time, your services might start to look like cells in a petri dish; they split apart, evolve in their own direction, and new patterns emerge. The benefit is, the system allows developers to react to those patterns while at the same time, providing an environment with defined contracts and protocols that make it easy to play around with different ideas.
