Questions to Ask Before Choosing Microservices

Today’s software teams are under increased pressure to become more agile, more flexible, and more scalable, continuously increasing the velocity of their development efforts with every deployment.

As a result, many businesses are moving away from the legacy monolith applications holding them back from competing in today’s competitive, ever-changing digital world. Instead, companies are decoupling their applications and turning toward microservices, in hopes of achieving the success of high-profile early adopters like Google, Twitter, Uber, Amazon, Netflix, and PayPal.

Competitive advantages aside, deciding whether to adopt microservices should not be taken lightly. In this article, we’ll go over a list of microservices questions you should ask (and answer) before kicking off a migration initiative.

When to Choose Microservices

Understanding when to choose microservices versus embracing another solution is a major factor when it comes to narrowing in on a decision.

There’s no doubt that microservices bring several major benefits to the organizations that adopt them. The key thing to understand is that microservices only provide those benefits under the right circumstances.

For one, your organization should not adopt microservices unless they have embraced an Agile, DevOps culture. If you’re still working within a siloed, traditional organization structure, you’re not ready for microservices. Agility, autonomy, and close collaboration are required to reap the benefits of microservices.

Second, you’ll need to have a specific use case for each service in your application. For instance, you might have a service for processing payments, another for word processing, etc. You’ll also want to make sure that developers understand the context of each service and use consistent language within each service.

Find Out if Microservices Are Right for You by Answering These 9 Questions

  1. Do small changes to your application require expensive, time-consuming redeployment of the entire software suite?
  2. Could your internal and external users benefit from faster feature deployments?
  3. Will faster deployments offer an increased competitive advantage, such as the ability to reach market faster?
  4. Will decoupling your current application strengthen your system and result in increased reliability?
  5. Does your monolithic application host a large amount of unneeded functionality?
  6. Does your application rely on the ability to leverage the flexibility and scalability of the cloud?
  7. Do some services within your application require frequent, rapid deployments?
  8. Would your application benefit if you could use any programming language to develop new services?
  9. Are you dealing with large, diverse datasets where individual services could benefit from using their own storage solution?

If you answered “yes” to most of these questions, you’d likely benefit from moving toward a microservices architecture. Maybe you’ve outgrown your all-in-one monolith application and are dealing with a system that doesn’t support how you work today.

Or, perhaps you’re at a crossroads where you’re ready to scale, but your existing solution isn’t designed to support your vision.

Over time, legacy monolith systems become increasingly hard to manage and expensive to maintain. They’re often weighed down by outdated functionalities that no longer get used–which opens applications up to lag times, security issues, and complicated fixes, add-ons, and deployments.

Microservices questions that dig into the “how” that powers your strategy:

  1. What problems will this solution solve?
  2. How will it be secured—how will you handle security settings and authentication across all endpoints?
  3. How will it scale?
  4. How will it handle failures?
  5. How will you test it? Do you have a continuous integration system in place?

Cultural Microservices Questions

As we’ve mentioned before, culture also plays a major role in whether microservices are right for your company or not.

  1. How mature are your Agile and DevOps culture?
  2. Are your employees empowered to make decisions?
  3. How is your organization structured?
  4. Are there enough resources to support the effort?
  5. Does your team have enough experience?
