Microservices and DevOps
Microservices bring additional productivity to DevOps by embracing a common toolset, which can be used for both development and operations. That common toolset establishes common terminology, as well as processes for requirements, dependencies and problems.
Which in turn, makes it easier for Devs and Ops to work with one another, allowing those entities to work jointly on a problem and successfully fix a build configuration or build script. DevOps and micro services work better when applied together and bring some significant benefits including:
Microservices offer increased agility, which fuels the ability to roll out new versions of a service. That agility is due to shorter build, test and deploy cycles. Microservices can also incorporate the flexibility needed to employ service-specific security, replication, persistence and monitoring configurations.
A fault with a microservice only affects that microservice and its consumers. When monolithic applications experience a fault, the entire monolith may fail.
Releasing a new version of a particular microservice requires very little downtime, whereas rolling out a new version of a service in the monolithic application normally requires a full restart of the entire monolith.
Microservices can be scaled independently using pools, clusters, grids. That deployment characteristic makes microservices a great match for the elasticity of the cloud.
Microservices offer the flexibility to consume new frameworks, libraries, data sources and other resources. As loosely coupled, modular components, microservices prove to be easier to work with and support dynamic discovery and binding via a registry.
Microservices can leverage the agile methodology, where the application development effort is divided across teams that are smaller and work more independently.
