What is Microsercies?

What is Microsercies?
Microservices are an architectural approach to building applications. As an architectural framework, microservices are distributed and loosely coupled, so one team’s changes won’t break the entire app. The benefit to using microservices is that development teams are able to rapidly build new components of apps to meet changing business needs

List of Principals of Microsercies?

1. Single concern microservice - This means that a microservice should do one thing and one thing only.
2. Discrete microservice boundaries - A microservice must have clear boundaries separating it from its environment.
3. Transportable microservice - A transportable microservice can be moved from one runtime environment to another with little effort.
4. Carry-its-own-data microservice - A microservice should have its own data storage mechanism that is isolated from all other microservices.
5. Inherently ephemeral - The principle that a microservice is ephemeral means that it can be created, destroyed, and replenished on-demand on a target easily, quickly, and with no side effects.

Top 15 tools for Microsercies Implementations?

**** API Management and Testing

1. API Fortress
   Both an API test and health tool, API Fortress automates the functional testing, health monitoring, and load testing of enterprise APIs. It’s designed to be practically code-free and is built entirely around modern API architectural practices and patterns.

2. Postman
   An API development suite for individual devs and teams, Postman allows you to easily run UI-driven API tests. As Postman is a powerful HTTP client, RESTful API exploration becomes a breeze. Users can quickly put together simple and complex HTTP requests to test, develop and document APIs in no time.

3. Tyk
   Fast, scalable, and modern, Tyk is an out-of-the-box open source API management platform.
   Whether you need to install on-premise, as a cloud service or if you prefer to use a hybrid of both, Tyk is versatile. With Tyk, you gain high availability and low latency, on top of the lowest total cost of ownership.

**** Messaging

1. RabbitMQ
   RabbitMQ helps you utilize patterns to communicate between your microservices to scale applications and solve most distributed systems’ problems. Connect competing microservices using RabbitMQ in a microservice environment or in any other distributed system. You can also use the tool to exchange events between services.

2. Amazon Simple Queue Service (SQS)
   Amazon SQS provides robust, flexible, and reliable microservices communication. A message queue service like Amazon SQS solves several developer problems if choosing a publish-subscribe microservices’ communication model. In addition to better security, queues make messaging stronger by providing a reliable place to store pending messages.

3. Apache Kafka
   Message queuing is necessary within microservices architecture to handle all the inter-microservice and microservices-external-source communications. Whether this is for intensive data processing or API calls, etc. Apache Kafka is a distributed stream processing platform with high fault tolerance and resilience.

4. Google Cloud Pub/Sub
   A fully-managed real-time messaging service, Google Cloud Pub/Sub allows you to send and receive messages between microservices. Integrating your application with Google Cloud Pub/Sub will help handle all the asynchronous requests you are bound to receive and endeavor to mitigate the time that users wait for a response.

**** Monitoring

1. Logstash
   You’ve got the microservice deployed, and now you have to monitor it. Many elements go into monitoring though. For example, is a particular microservice responding well or are tweaks needed? Are other system parts working correctly, such as the databases? You'll want to check the logs and to do that, Logstash is a great tool. It’s an open source platform where you can centralize, stash, and transform data.

2. Graylog
   Use Logstash in conjunction with Graylog as a centralized server. It bills itself as easy to use, interactive, and fast. A user can easily explore data with the system. It’s scalable, and it is designed to grow with a user’s business depending on the needs that develop. Graylog is not free, but it’s affordable.

**** Kube Development

1. Kubernetes Whilst Kubernetes certainly comes under container orchestration, in the world of microservices, it also deserves a section to itself. Kubernetes has become the gold standard for best deployment practices. When it comes to container scheduling, load balancing, service discovery, and more, Kubernetes is particularly powerful.

For microservices developers that build with Kubernetes, here are some other open source tools available.

1. Telepresence
   Telepresence is a speedy local development for Kubernetes. Waiting for containers to deploy can be aggravating. With Telepresence, a hybrid model can be employed. So, coding of your service is done locally on your laptop with simultaneous connecting of services in your Kubernetes by away of a two-way proxy. Not recommended for production use, but great for development.

2. Istio
   Istio supports service deployment on Kubernetes. Add reliability, security, and manageability to microservices communications through Istio’s service mesh technology. The service mesh tech allows you to improve the relationships and interactions between your application and microservices.

3. Minikube
   Minikube is a handy open source tool that lets you run Kubernetes on your laptop without the need for WiFi. For example, this comes in handy when you’re on an airplane and you need to code, but you don’t have WiFi to do so.

**** Orchestration

1. Conductor Conductor is Netflix’s microservices orchestration engine as part of its Netflix OSS ecosystem. Conductor runs in the cloud and implements a flow orchestrator to carry out tasks through microservices. It also facilitates control and visualization of all interactions between microservices.

**** Programming Languages

1. Elixir
   Expand your programming repertoire with Elixir; a concurrent, functional, general-purpose programming language that works alongside the bytecode seen on the Erlang VM (also known as BEAM).

2. Spring Boot
   Simplify the creation of REST-based microservices with Spring Boot frameworks in just a few lines of code. You can use one of the available Spring Boot examples or the Spring Initializr to get started quickly and easily.

**** Toolkits

1. fabric8
   An open source platform-as-a-service tool, fabric8 helps devs provides configuration management system through git, handles IP address complexity and port mappings, and is able to perform load balancing to services. Fabric8 also offers scalability and high availability.

2. Seneca
   Build message-based microservice processes with ease through Seneca, a microservices toolkit for Node.js. With this toolkit, you can write clean, organized code and easily systematize the business logic of your app.

**** Google Cloud Functions

1. Google Cloud Functions Google Cloud Platform’sCloud Functions (BETA) are lightweight, serverless, and easy to deploy and maintain. The console provides real benefit to developers building de-coupled microservice applications through event-driven architecture. Spin up a container and pay on a cost-per-use basis. Plus, chain Cloud Functions to other products through some of Google Compute’s APIs.

**** Architectural Frameworks

1. goa
   Goa provides a framework for building REST APIs and microservices in the Golang programming language using a design-first approach. With goa, devs can design APIs and then generate everything else to accompany it; from JSON documentation to command line applications and a JavaScript library, etc. All the goadesign services run on top of the Google Cloud Platform.

2. Kong
   Available for install on multiple operating environments, Kong leverages numerous read-to-deploy plugins to help with the development and deployment of microservices. With Kong, you can leverage microservice and container design patterns to quickly build API-centric applications.

**** Serverless Tools
Serverless tech or Function-as-a-service is a huge part of microservices. It optimizes the methodology of breaking things down into their smallest function.

1. Claudia
   Get started with Lambda microservices with Claudia and focus on business rather than dealing with AWS deployments. Claudia deals with deployments for AWS Lambda and API Gateway. Claudia also automates error-prone deployment and configuration tasks, working straight out of the box. On top of all this, it contains enhancing tools such as Claudia API Builder and Claudia Bot Builder.

2. Apache Openwhisk
   As well as being an event-based programming service, Apache Openwhisk is a readily extensible serverless computing platform that supports devs in creating, testing and connecting actions to others as well as helping with debugging. Use OpenWhisk through a Docker installation on Mac, Windows or Linux.

3. Serverless
   This tool does exactly what it says; a console which combines FaaS/serverless technology with other cloud services to help devs build complicated systems. Serverless also offers scalability, integrated security, and improved operability.

4. Kubeless
   Kubeless is a Kubernetes-native serverless framework that lets you deploy small bits of code without having to worry about the underlying infrastructure plumbing. Kubeless is aware of Kubernetes resources out-of-the-box and also provides auto-scaling, API routing, monitoring, and troubleshooting. Kubeless fully relies on K8s primitives, so Kubernetes users will also be able to use native K8s API servers and API gateways.

5. IronFunctions
   IronFunctions is an open source serverless platform or FaaS platform that you can run anywhere. IronFunctions is written on Golang and really supports functions in any language. The main advantage of IronFunctions is that it supports the AWS Lambda format. Import functions directly from Lambda and run them wherever you want.

6. AWS Lambda
   AWS Lambda provides infrastructure-less servers for your microservices build and you’re charged on a pay-per-use rate. Lambda can also be used in combination with AWS API Gateway which lets you host a REST or API service. The two together allows your API to serve any requests made by users.

7. OpenFaaS
   An open source serverless software program that promises “Serverless functions made simple.” OpenFaaS helps you package any process or container as a serverless function for either Windows or Linux. As with any serverless technology, the benefits are that developers can concentrate on delivering business value rather than handling day-to-day management of the underlying application structure.

8. Microsoft Azure Functions
   Event-driven, compute-on-demand functions that enhance Azure’s existing application capabilities. Scale-based and on-demand, you will only pay for the resources you use. Azure Functions helps developers connect to data sources/messaging solutions which makes it easy to process and react to events. Devs can also leverage Azure Functions to construct HTTP-based API endpoints.
