Understanding emerging MicroServices trends in functionality, protocols, containers, data, and infra
Formerly, when using MicroServices, ever-present infra-related issues were problematic. Luckily, through the tremendous open source community, many of these problems have been dealt with head-on. Explore the highlights of 5 microservices trends to look out for in the near future.
1. No More Worries about Protocols
Burdensome uncertainty in protocol marked a popular trend in the realm of microservices. Should it be the regular HTTP? Why not the recently matured HTTP/2? Indeed, deciding the best protocol has become worrisome and tedious. However, new developments in protocol will likely eliminate this worrisome task. Why, you ask? There will be the rise of protocol agnostic platforms. So then, users are enabled to communicate with other protocols without intense translation middleware methodology. Additionally, it would in turn aid better connectivity of microservices. Finally, there will be more robust protocol combinations such as GRPC ->HTTP, HTTP->GRPC, and GraphQL->GRPC.
2. Not Just Functions but Features as a Service
Currently, there are numerous available APIs. It becomes easy to kick start functionality with the aid of helpers such as Firebase and services on AWS. When microservices are programmed in a key-based direction, they can act as a feature geared towards multiple applications. A typical example is the authentication of every API, called using an app id. This helps individuals to design really fascinating feature pools and make room for their easy cloud orchestration in an agnostic manner.
3. Container Driven CI/CD
Argo, as well as other projects, tends to treat containers like tasks. Even the version 1.6 of Kubernetes initially introduced initContainers as post tasks geared towards extra configuration. In 2019, adopting containerization to abstract CI and CD will be a major trend. It would be better to treat them as cron job, rather than hook them up in an infra. Also, they should be treated as occurrences resulting from an event firing via code, rather than getting them hooked up in an infra.
4. Microservices Shared Data/Contexts
When it comes to the pattern of building microservices, processes are becoming increasingly ‘loosely coupled’ as well as stern. There’s an emergence of several event-driven tools; typical examples include ‘Serverless’ Event Gateway. This pitches event-driven microservices.
Automated microservices can be enabled via listening to a hitch-free login event of a different microservice inside an application, without manually firing even one event. At the same time, it possesses the ability to control what gets to third party listeners. It’s time to treat today’s microservices with dependencies alongside communication.
5. Less or Zero Worry about Infra
Don’t worry anymore about infra, but focus on their application requirements. The Serverless style will become a focus this year, to enable easy environments to switch away from “always on”. Besides, there’s a need to support additional languages. There should be a possibility for using any language and making it serverless.
