Many cloud providers now provide what are called "functions as a service." Azure cloud offers Azure functions, and Amazon offers Amazon functions. Your company may also wish to provide its own REST-based services that perform server-less computing and the purpose of this essay is to review the basics of how to maintain, manage versions, and ensure optimal performance of our REST-based Microservices.
Many REST-based functions have now evolved into Microservices. The main focus of these REST-based services are:
- Version Control
Maintaining Microservices, whether a simple bug fix or an enhancement to a service, is often challenging. Code needs to be changed, tested and published to the service. Code changes can create other problems like backward compatibility issues or issues with changing parameter types so quality assurance efforts work to ensure nothing else breaks when these changes are made.
Most updated services use versioning, with the URL typically being referenced with “v1/function name” to make sure that the correct version is accessed by an end-point. In most cases, due to non-session based calls, REST APIs can take time to initialize and execute.
REST APIs or services have evolved to Microservices, meaning most implementations of Microservices are still code-based, making development, maintenance, and versioning more challenging. FlowWright’s implementation of Microservices solves many of these use case challenges by using more modern architectural models.
Firstly, there’s no coding for Microservices, FlowWright offers a no-code drag and drop visual development environment: design a workflow definition graphically and then convert that into a Microservices/function. As cloud-based serverless functions are becoming more and more popular, the maintenance of these services is crucial. FlowWright Microservices provides a centralized services management infrastructure, including management within distributed environments.
Microservice functions scale well in the cloud because they are built for the cloud infrastructure, but these Microservices can operate very different in different environments ( for example Microsoft Azure versus Amazon Web Services.) FlowWright has the advantage of being designed to host and execute Microservices/functions as a service running on any cloud platform, including private/public and hybrid clouds - and delivers not only superior performance but also an organized platform for designing and maintaining high quality, high-availability Microservices.
