Service oriented architectures (SOAs) have been around since the 1990s, providing an alternative to monolithic applications – essentially collections of coarse grained components that communicated with each other. But, while SOAs used to serve as a revolutionary approach to solving the architectural problems challenging businesses, it’s simply no longer the case in today’s business landscape.
Essentially, one could say SOAs were ahead of its time, as the hardware wasn’t powerful enough, and the right standards and technologies simply weren’t available. Back in the 1990s, not only were processes large, encompassing numerous features and functions, but networks weren’t fast enough for a fully distributed architecture with independent execution contacts.
Luckily, that’s no longer the case. Applications today aren’t limited by the infrastructure they run on. Instead, they can control their fundamental infrastructure technologies, turning them into services to be harnessed on demand and programmatically during application execution. Hence, the argument of SOA vs microservices.
SOA vs Microservices: Why Microservices Makes Sense
Microservices, or cloud-native applications, represent a new application architecture that decomposes the large, monolithic applications of the past into a set of small, discrete functions or processes that are built and evolve independently of their peers. In short, microservices can enable businesses to effectively compete by delivering features, services and solutions in minutes.
The main purpose? To make it easier for DevOps teams to develop systems with reusable component parts that can be maintained and distributed independently, as well as utilized by multiple applications and services throughout an organization. With software services becoming more and more essential to the strategy at the core of the business, microservices have become essential at maintaining a competitive edge.
That’s because, thanks to application development modernization, features and functionality need to be delivered with high quality faster, and with better user experiences. So, in order to continue to satisfy customer demand long-term, it’s imperative to move past outdated service-oriented architectures, and embrace our new friend in town: microservices.
