The term “microservices” describes a type of architecture where one application is made of small, loosely connected, but independently deployable, services. This is different from the norm, where multiple services are firmly coupled into a single, unchangeable application. Instead, microservices piece together a single application from a few loosely connected services. For cloud-native applications, this is becoming the norm.
While microservices help businesses scale and optimize their deployments more efficiently, they pose a security issue to the uninitiated. For the most part, this is due to some microservices not having built-in or user-friendly security controls. Additionally, another part is associated with inherent security challenges posed by developers, or a DevOps structure – we’ll expand more on that in the next section.
When you use microservices, you’re creating a complicated cloud environment that usually utilizes many databases – all of which need to be managed and secured on an ongoing basis. Not only that, but microservices often dabble in multi-cloud – so a single microservice may concurrently use applications from Azure, AWS, and other cloud providers. For that reason, it’s best to use a platform that will help you manage all of your cloud deployments from one place.
