The microservice style of architecture is a way of building an application as a group of various services. Put simply, it means building an application using many single-function modules or parts. Each module has a clearly defined interface and intended operation.
As organizations shifted away from monolithic architectures and toward service-oriented architectures in the early enterprise software application development days, microservices emerged. This evolution continues to be driven by the multifaceted demands of businesses across verticals.
As development speeds continued to increase, so did the need to move away from old and dysfunctional applications. These single autonomous units could not be easily changed, so any upgrades or augmentations to an application were slow and impacted the entire system. Simple changes to one piece of code could mean redeploying an entire new version of the software.
Microservices solved this problem by offering the ability to build an application as a collection of small and independently deployable services, or parts, that could be updated and changed without affecting the entirety of the system.
Microservices structure an application in such a way that it is built of various smaller parts, or services, that can be independently deployed.
This structure is critically important to modern software development because it enables agility and speed.
Key benefits of the microservices structure include:
Some of the reasons developers use a microservice architecture include:
Although microservices have many advantages, they are not without challenges. Some of those challenges include:
Seeker® is an interactive application security testing (IAST) solution from Synopsys that supports both web-enabled and microservices application security testing. Seeker provides continuous runtime application security testing, monitoring, and autoverifications. It gives teams a comprehensive view into multiple composite project interactions, communications, and data flow in the back end.
Seeker can verify, alert, and report any detected critical findings in real time to the impacted team, and it provides crucial information instantly. It also provides in-depth visibility into hundreds of endpoints and tainted data with data flow mapping and cross-microservices project analysis.
Teams get actionable insights with detailed stack traces, source locations, warnings about vulnerable open source components and codebases, and sample tips for timely remediation, so they know what security practices they need to implement, and when they need to do so.
