Why Microservices Architecture is so BIG for Today’s Financial Services Industry

Guest Post by Anand Bhadouria, HPE Cloud CTO

I was watching a documentary on monolithic structures the other day. They were all very impressive. They had lasted for centuries and showed that the societies who had built them were very advanced. But the fact that they were monoliths now made them useless.  They couldn’t be moved. They couldn’t adapt or change. So they became relics. Impressive relics, but relics nonetheless.

A similar process is happening today with monolithic IT architecture in financial services industry. Useful back in the “dawn of time,” they are also now relics that cannot keep up with the rapid changes occurring in the financial services industry (FSI). So they are being replaced by cloud-native applications and microservices.

 What’s the BIG deal with microservices?

Microservices represent the next step in an evolution from physical to virtual to cloud to cloud-native. They are a set of small, narrowly-focused, independently-deployed services that communicate with each other in a language-agnostic manner. Their architectures are highly-scalable and highly-available. They also easily support frequent updates and can be made available on a Software as a Service (SaaS) basis. 

 So when the marketplace changes, creating new customer needs that open up new opportunities, your cloud-native environment changes just as quickly to allow you to respond to the change and capitalize on the opportunities. What would take forever for the monolith architecture to do can happen in no time at all with a microservices architecture.

 Combined with the flexibility and power of a hybrid cloud, the microservices architecture delivers mega capabilities and benefits. To learn more about microservices architecture I included a technical overview video.

 Taking the big step to microservices

A number of best practices have been established to help ensure that Software as a Service (SaaS) - also called web apps - delivers maximum benefits. For example, the twelve-factor app is a methodology for building software-as-a-service apps that:

  • Use declarative formats for setup automation, to minimize time and cost for new developers joining the project;
  • Have a clean contract with the underlying operating system, offering maximum portability between execution environments;
  • Are suitable for deployment on modern cloud platforms, obviating the need for servers and systems administration;
  • Minimize divergence between development and production, enabling continuous deployment for maximum agility;
  • And can scale up without significant changes to tooling, architecture, or development practices.

 

The twelve-factor methodology can be applied to apps written in any programming language, and which use any combination of backing services (database, queue, memory cache, etc).

 More information

Complete information on the twelve factor methodology is available here. For additional information on how cloud-native applications can drive flexibility and results in the financial services industry, check out the HPE Helion Stackato site.
