MICROSERVICES : SOA DONE RIGHT

Enterprises are pushing to deploy microservices-based applications to keep up with competitive pressures and higher demands for a responsive, best-in-class user experience.

Whether you call them microservices (the industry favorite), picoservices, uniservices, decoupled services, or even “SOA done right”, one thing is clear: enterprise deployment of microservices-based applications is no longer a fringe concept enjoyed by a handful of early adopters. While microservices–which may not be so very small, in fact–are being embraced across technology platforms, they have found a real home in Reactive systems. Indeed, a recent survey on Reactive systems of over 3000 respondents revealed that microservices-based architectures account for just over 50% of applications being built and deployed by enterprises today. Reactive systems, as described by the Reactive Manifesto as message-driven, elastic, resilient and highly responsive, are fueling the new wave of applications that are deployed on everything from mobile devices to cloud-based clusters running thousands of multi-core processors. Users expect millisecond response times and constant uptime.

Microservices-based applications excel in the environment enabled by Reactive systems, starting with an asynchronous, non-blocking, message-driven foundation to enable a high level of resilience and elasticity to create a system that is always responsive regardless of what’s happening to it. Enterprises are pushing to deploy microservices-based applications to keep up with competitive pressures and higher demands for a responsive, best-in-class user experience. Yet the gap continues to increase between the enterprise development teams building Reactive applications, and the requirements needs by Ops teams to deploy and manage them. Ops is unable to tackle these challenges with what they have, as we reviewed: Existing Operations processes and methodologies are inconvenient for Reactive microservices-based systems Existing Operations tools and technologies have not been designed from the start for Reactive microservices-based systems The costs and risks caused by improper tools are higher than ever With these factors adding to the already challenging task of re-architecting traditional full stacks to become more Reactive, the last thing Operations needs to worry about is how on earth they’ll be able to keep these systems online. What’s they need is a non-disruptive, low overhead technology that was designed for asynchronous, distributed, fault-tolerant systems from the ground up. This tool needs to be a “conductor” of clusters across availability zones, that lives inside the cluster and self-heals failed applications, nodes and even network partitions.
