Top Microservices Frameworks

Microservices architecture is a methodology wherein fragment monolithic single application into small applications and services which executes lightweight applications. Business capabilities and independently deployable models are the primary goals for Microservices development. Microservices architecture built using different programming languages and deployed them and connect.

Benefits of Microservices

  • Adoption of New technology and process.
  • Independent scaling of applications.
  • Cloud-ready.
  • Seamless integrations.
  • Effective Hardware utilization.
  • Service level Security.
  • API-based functions for reuse effectively.
  • Independently Develop and Deploy applications.

Selection Criteria for Framework Selection

The following are some of the critical aspects that can be considered while choosing the proper framework:

Microservices Architecture: Breaking the Monolith

This article summarizes the webinar ‘Breaking The Monolith’, presented by Daniel Gutiérrez Saavedra, Senior Software Engineer at Zartis. You can watch the full webinar, which also includes a Q&A session below!

Are you working with monolithic systems and legacy applications? Are you looking for ways to modernize your architecture and switch to microservices? This article will cover the ways you can break up a monolithic application into smaller pieces that make up a modular system.

Microservices Implementation using (Spring Boot and Cloud)

In recent years, microservices architecture has been a preferred choice for application development due to various advantage that architecture brings in. However, every architecture comes with various pain areas and microservices architecture is no different. In a microservices architecture, there are many independently developed services which will serve some specific functionality. These services will be deployed in different -2 Infrastructure and they would communicate with each other and some external system through API or Events to complete the system functionality. We should minimize this kind of direct dependencies on other microservices, but in some cases, it is unavoidable. So we need to managed these dependencies and this is where the microservices architecture principle comes into the picture and explains, what all concerns (Service Discovery, Circuit Breaker, Distributed Tracing, routing, Connector, Configurations) need to be considered while developing and deploying these small services. 

So, here I am trying to depict the diagram, how can microservices be built using Spring boot and be deployed and managed using Spring Cloud.

Business Impact: Before and After Microservice-Based APIs

IBM, UNISYS, HP, Digital, Siemens, Honeywell — Big global brands still depend on their legacy systems.
You may also like: The Role of APIs in a Microservices Architecture

Using data storage and access methods — like VSAM, IDMS, IMS, DB2, Oracle, and ADABAS — to store and rapidly access data through mission and business-critical applications are written in COBOL, Assembler, Fortran, ADS, RPG, and Natural, these business giants now find themselves unable to stay on the cutting edge in terms of speeding delivery of innovative digital channels and applications.

When you have legacy systems and must cater to customers and prospects that are heavily reliant on digital services delivered via mobile or Web, you need to find a way to close that gap between old technology and modern demands. The answer is microservices.

Part 1: How Canary Deployments Work in Kubernetes, Istio, and Linkerd

This is the first of a two-part series on canary deployments. In this post, we cover the developer pattern and how it is supported in Kubernetes, Linkerd, and Istio. In part two, we’ll explore the operational pattern, how it is supported in Glasnostic, a comparison of the various implementations, and finally the pros and cons of canary deployments.

A canary deployment (or canary release) is a microservices pattern that should be part of every continuous delivery strategy. This pattern helps organizations deploy new releases to production gradually, to a subset of users at first, before making the changes available to all users. In the unfortunate event that things go sideways in the push to prod, canary deployments help minimize the resulting downtime, contain the negative effects to a small number of users, and make it easier to initiate a rollback if necessary. In a nutshell, think of a canary deployment as a phased or incremental rollout.

Episode 53: Sam Newman Turns Up the Microservices Dial

In Episode 53 of DevOps Radio, host Andre Pino is joined by industry thought leader Sam Newman. Sam is an author, speaker, and independent consultant (previously at Thoughtworks) who specializes in cloud storage and microservices. In addition to sharing more than 20 years' worth of industry insight, Sam provides analogies and examples a plenty for listeners who may still be trying to grasp what a microservice is. Sam jokes that he's been stuck in an enjoyable rut for the last 15 years, working with interesting people like Jez Humble and building the Lego XP game that helped people learn Agile (like many of us, if there's an excuse to buy a Lego, Sam's up for it).

As the author of Building Microservices and an expert on the topic, Sam says organizations need to have a good reason for using microservices. For the listener's benefit, Sam compared microservices adoption to a dial — not a switch — where you steadily continue to turn it up all the time instead of fully committing and flipping the switch right off the bat. He also reiterates that developers need to have a clear understanding of what they're trying to accomplish with microservice adoption, otherwise it can be hard to justify the time it takes to implement.

A Quick Guide to Microservices With the Micronaut Framework

The Micronaut framework was introduced as an alternative to Spring Boot for building microservice applications. At first glance, it is very similar to Spring. It also implements patterns like dependency injection and inversion of control based on annotations, however, it uses JSR-330 (java.inject) to do it. It has been designed specifically for building serverless functions, Android applications, and low memory-footprint microservices. This means that it should have a faster startup time, lower memory usage, and be easier to unit test than competing frameworks. However, today I don't want to focus on those characteristics of Micronaut. I'm going to show you how to build a simple microservices-based system using this framework. You can easily compare it with Spring Boot and Spring Cloud by reading my previous article about the same subject Quick Guide to Microservices with Spring Boot 2.0, Eureka and Spring Cloud. Does Micronaut have a chance to gain the same popularity as Spring Boot? Let's find out.

Our sample system consists of three independent microservices that communicate with each other. All of them integrate with Consul in order to fetch shared configurations. After startup, every single service will register itself in Consul. The applications organization-service and department-service call endpoints exposed by other microservices using the Micronaut declarative HTTP client. The traces from communication are sent to Zipkin. The source code of the sample applications is available on GitHub in the sample-micronaut-microservices repository.

Monorepo’s for Microservices Architecture

As enterprises modify and optimize their architecture for the customer-centric digital commerce boom, many enterprises lack the institutional knowledge necessary to quickly make the transformation. Here at commercetools, we have built a cloud-first API only commerce architecture that most companies wish to emulate within their own ecosystem. Thus, our customers frequently ask us to help guide them in their transformation.

This leaves us in a difficult position. Developers are always trying to find the balance between extremely opinionated systems and being forced to reinvent the wheel. commercetools strives to allow developers total flexibility when leveraging its API, from programming language, to SDK options, to choosing REST or GraphQL. The unopinionated nature of commercetools leaves developers with the responsibility of choosing frameworks, cloud architecture, and configuring all the tooling necessary in between.
