A key trend in software architecture for 2020 is microservices. Microservices architecture involves loosely coupled services arranged as a single application. There are many different types of microservices, and each has its own interface. Because microservices are developed independently, applications are easier to maintain.
To support microservices, a growing number of tools and technologies have emerged. What is the best method for choosing the best method?
The 5 top technologies for building microservices architecture have been compiled below to help improve your microservices development.
Adapting to changing conditions and client needs more rapidly has become a necessity in today’s business world. Keeping up often requires fast deployment, effortless maintenance, and continuous accessibility. A lot of this can still be handled by traditional architecture, but it’s still limited. An application development approach that is more dynamic and scalable can become a critical component of the future success of the company.
A microservice architecture is an example of such an approach. As opposed to traditional monolithic architectures, microservices enable simpler and quicker software changes. These interchangeable, upgradeable, and scalable parts are then combined to create applications. In an ideal world, modular architecture would allow businesses to deploy innovative functionality in an agile manner, accelerating business growth. While this model is more complex then a monolithic one, it can also reduce complexity. There are many more tradeoffs to consider.
Microservice architectures have evolved as they progress along with the hype cycle from inflated expectations to disillusionment and onto an upward path towards enlightenment. How do microservices compare with traditional services? Find out what we run into most often here.
A microservice – or microservices architecture – is a collection of loosely coupled services that is arranged or architected as a microservice. Characterise the microservices by the following characteristics:
In contrast to traditional monolithic architecture, microservices architecture breaks applications into smaller components. Design the services to address a variety of business issues.
Microservices simplify deployment processes and allow developers to build cloud-ready, high-end software rapidly.
You make a single app more changeable, scaleable, and deployable by fragmenting it into smaller programs. Data is stored in various ways in the microservices architecture.
In response to microservices’ growing popularity, many new technologies and tools have come up. Let’s look at some of the most effective ways to develop microservice architecture.
Understanding microservices requires an understanding of monolithic applications and what led to the shift to microservices in recent years.
The word monolith refers to a complete composition. In monolithic applications, components are combined into a single program on a single platform as part of a single program. Therefore, the following components can be used:
It is known as a monolithic application if all of its functionalities are contained in one codebase. All of us have designed monolithic applications where different features were required to solve a specific problem. As part of our application development, we design the presentation, service, and persistence layers, and deploy that codebase in a single jar/war file. We are dealing with a monolithic application, where “mono” refers to a single code base encompassing all required features.
But if we already were using monolithic applications, how did microservices come about?
This increased autonomy (speed to market), improved fault isolation (reliability), and reusability and scalability of development teams are all benefits of microservices.
Amazon, Netflix, Spotify, and Uber are all building products on the basis of microservices architecture. Microservices have the following advantages over traditional monolithic applications:
APIs or communication gateways, service discovery, the service itself, and a database or cache typically make up a microservice architecture.
The implementation, migration, and maintenance of microservices architectures present challenges, too. Microservices architecture is known to pose a number of challenges, including:
There are various tools, versions, and frameworks suitable for executing microservices. Take a look at technologies for microservice development!
Containerization uses Docker to create self-contained packages and run software in them. As a result, containerized applications are deployed and handled manually by Kubernetes, which automates that process. Therefore, it is easier to make scheduling and scaling containers with this tool.
One can easily create a responsive microservices architecture by combining these technologies.
A microservice communicates with another microservice through the use of REST (Representational State Transfer).
Microservices can communicate directly through HTTP using this architectural design pattern. It provides standard responses and requests in formats such as JSON, HTML, and XML.
Designed for multiple complex application topologies containing many nodes, Prometheus is a monitoring system and alarming tool. In this tool, use key-value labels to execute multidimensional data, as well as to provide data storage and scraping. FilterData based on labels using Prometheus, an easy and rapid tool.
With Prometheus, you can see statistics and alerts in a grand visual way. It is possible to visualize data and select tracking options based on time to find anomalies easily. With its simplified dashboard interface and various graphing instruments, it is an excellent monitoring tool.
Its versatility makes Redis an ideal technology for many applications because it provides a variety of features. A high-speed, flawless NoSQL database is designed to fix complicated coding issues by using easy commands and facilitating elasticity in data structures. As well as a core data model, Redis is able to manage streams, hashes, and more.
Platforms like Redis are highly performant.
Manage thousands of operations instantly. Also, read the operations in a millisecond. Among its other benefits, it offers distributed caching. It focuses on data persistence, seamless data distribution among microservices, and secure temporary data storage.
Microservices can communicate with each other thanks to Consul technology. Service discovery has unique features that make it stand out from other technologies. As a result, you can use Consul with other technologies too since Consul Templates and DNS interfaces support.
Setting up a synchronous system with Consul is helpful. In fact, its infrastructure meets all the basic requirements for synchronous microservices.
By using this protocol, consistent protocols can be applied for both pub/sub messaging and queueing. Message brokers such as RabbitMQ are considered unique by most developers. Using RabbitMQ, which adds another layer of security, you can use SSL.
RabbitMQ’s multifaceted performance is superior to other message brokers. Almost half a million messages can be sent within a second using the clustering feature.
Usually, using an API Gateway is a better approach. API Gateways serve as the single entry point into a system. Facade is an object-oriented design pattern similar to this. It provides an API that is tailored to the needs of each client and encapsulates the internal architecture of the system. In addition to handling authentication, monitoring, load balancing, caching, request shaping, and static response management, it might also perform other duties.
In addition to routing and composition, API Gateways translate protocols. API Gateway handles all client requests. Once the microservice is determined, requests are routed to it. API Gateways often aggregate the results of multiple microservices to manage a request. HTTP and WebSocket are web friendly protocols and web unfriendly protocols are used internally.
Clients can also request a customized API through the API Gateway. Let’s consider the scenario for product details, for example. With the API Gateway, clients can access the product details (/productdetails?productid=xxx) in one request with one URL. Using the API Gateway, handle the request by combining products, reviews, recommendations, etc.
API Gateways like the Netflix API Gateway are great examples. As a result, there are hundreds of Netflix users around the world and their devices include TVs, set-top boxes, smartphones, gaming systems, tablets, etc. Initial aims of Netflix’s streaming service were to provide one size fits all APIs. The devices and their unique requirements meant, however, that it did not work well for the diverse range of devices. By running device specific adapter code, they provide an API tailored for each device through an API Gateway. Typically, an adapter invokes 6 to 7 backend services for every request.
Take a closer look at microservice architecture and its benefits.
Microservices are profitable because of their isolation and resilience. In case an application component fails, developers are able to use another service to keep the application running. Using this method, engineers can add and deploy components without having to change the entire app.
Microservices, are made of simple components, make it easier for developers to scale up or down based on a specific element’s requirements. Isolate the applications from massive changes when they are running correctly. Businesses working with different platforms and devices can benefit greatly from microservices.
Microservice architecture can be easily understood in contrast to monolithic application which is not that easy to understand. Microservices are a better pick if you plan to grow your development team.
Microservices allow developers to select the right tools for the right job. Using a different language or framework for each server will not affect communication between microservices.
Changing features doesn’t require changing the codebase since microservices operate separately. Therefore, you will be able to deliver the app more quickly.
Developers cannot predict what kind of devices their apps will run on, so microservices are the best choice. It is possible for developers to provide controlled upgrades without slowing down or stopping the apps.
In spite of the pros of microservices, they come with cons. For example, teams use different languages, frameworks, and libraries. A team that hasn’t developed this independence may become paralyzed. Microservice architecture is the best option if you are developing a large, complex app.

It’s important to understand whether this technology is necessary for your company. Think about the case where your server already works. Microservice deployment requires the management of tens of thousands of services and a great deal of automation. In large enterprises with lots of workflows every day, microservices work best. However, if you have just started your startup, you should opt for the traditional route.
All members of the team need to grasp the concept of data modeling, API development, and asynchronous programming before they begin coding.
With microservices, developers are able to use a variety of programming languages and frameworks. Prepare your product’s technology stack in advance.
Every application depends on the database. You should consider splitting the database into several tiny DBs when moving away from traditional architecture.
Using Agile methodologies is the key to migrating to microservices. You might be able to break them up into several teams that work independently if you have a large team of developers.
Prepare your business and development team before integrating this technology. Developers and proper strategies are crucial to the success of the transition.

Monolithic architecture has many hidden pitfalls that microservices can help developers avoid. To keep your microservice architecture under control, you need tools such as Retrace. Unlike other APM solutions, Retrace manages and monitors the performance of your application at code-level, integrating application metrics and error logs into the monitoring system.
When you use microservices to extend a business, you can take advantage of the diversity of languages while building a reliable platform. Using a different technology or language for a different service does not necessarily make it effective. Due to the operation overhead of microservice architecture, adding a a wide range of programming languages to that can greatly increase performance overhead. By standardizing your microservices technology stack, you can reduce this risk by selecting the programming language that best fits your business needs. Evaluation criteria for microservices development programming languages are as follows:
Easily implement many microservice frameworks, platforms, and tools. Python, C++, Java, Node JS, and .Net are some examples. Therefore, let us explore in more detail the languages that enable microservices development:
Java is the perfect language for developing microservices because the annotation syntax is easy to read. When powered by Microservices frameworks, Java Microservices become much easier to develop. Increase the readability, especially when dealing with complex systems. In a single, isolated and independently deployed app, users have access to a user interface, component models, as well as back-end connections.
Furthermore, the Java EE standard suits to microservices applications, including:
Connect the Java Microservices easily to service discovery solutions, such as Consul, Netflix Eureka or Amalgam8.
In order to develop Microservices architecture, there are several frameworks available. There are several Java Microservice Frameworks available:
Golang can be an excellent choice for microservices development if you wish to enhance an existing project. The Golang programming language and its API support in terms of microservices architecture have made it popular. Due to the concurrency of Golang, you can expect machine and CPU productivity to increase. Develop Web services using its powerful standard. Also, develop a large, complex application easily. Microservices development with Go is possible with two excellent frameworks:
Apart from its simple syntax, Go microservices also offer excellent testing support, allowing developers to integrate tests flawlessly into workflows, in addition to writing robust tests.
Read our blog on why Golang is the best language for App Development.
With Python, you can integrate a variety of technologies into a high-level programming language. When compared to other frameworks and languages, prototyping in Python is faster and easier. For heavy implementations such as Django, it provides powerful substitutes. ASP and PHP are compatible with Microservices Python, which allows you to create a web service front end for the Microservice.
Read out blog, to find out which language is better Python or Go?
Microservices Python has all these benefits, making it an advantage over other languages. Developers use a RESTful API approach to implement Microservices Python – a comprehensive technique for remotely manipulating objects utilizing web protocols & software. Therefore, it is easier to monitor the application more easily since it is now divided into components. Choosing a microservices framework for your web application development can be difficult due to the wide range of options available. The following are some examples:
Over the past few years, companies and startups embracing microservices have gone to Node JS as their platform of choice. Consequently, microservices Node JS will be superfast for Input-Output (IO)-bound tasks because it’s built on the V8 runtime. The CPU-bound or the I/O-bound code is normally used to create Microservices Node JS applications. Programs requiring a lot of computation demand a lot of CPU power. NodeJS never blocks the thread that is running the main-thread when an IO call is made. Rather, the task is sent to the threads running the internal IO daemon. In order to streamline IO-bound tasks, Node JS Microservices gains popularity.
Often, innovative enterprises can achieve increased productivity, high performance, satisfaction for their developers, and lower costs with Microservices and Node JS together.
The ASP.Net framework enables easy, rapid creation of microservices based on APIs in .Net. Using Docker containers, it supports the deployment of microservices automatically. The .Net platform has APIs that enable microservices to enable services from desktop, mobile, web, gaming, and other applications. It is possible to adopt .Net microservices without having to rewrite an application in its entirety.
Microservices provide .Net developers with the ability to combine a variety of technologies between apps; this allows you to use .Net for just one part of your app rather than implement it everywhere. Use .Net microservices in combination with other programming languages, such as Java, Node JS, and C++. Develop Microservices using .Net core technology and then migrate to other services and microservices built with other technologies. All cloud platforms support .Net microservices as well.
Read our blog to find out how ASP.NET is the best for microservices development.
Microservices will lead to serverless architecture in the future; especially, the promise of realizing cost savings by paying only for the amount of compute utilized can be quite compelling. A microservice refers to any application, product or solution churned onto a more granular or modular level. Therefore, keeping in mind, starting a microservice architecture from scratch is not a good idea since it’s hard to define the boundaries of each service at the very beginning. Choosing the right microservices technology is the best way to achieve success. It is important to consider the tools you will use to implement other components of your application when making technology decisions. In addition, it’s important to know what your team already knows.

Microservices and traditional monolithic architectures are only set to continue evolving at the same time. Ultimately, developers must make sure they understand how their specific use cases work and do their due diligence.
Smaller companies may find it more efficient, quicker, and cheaper to start with a monolithic application, then migrate to microservices as soon as the product has matured enough. Microservices are ideal for large companies with millions of users, since they need scalability and availability that modular architecture can provide.
Several companies, like Amazon and Netflix, have been creating microservice-based apps with microservice architecture in order to reap the many benefits it brings. Therefore, see how they utilize this architectural pattern:
The Netflix architecture shifted from monolithic to microservices. What happened? Several hours passed before Netflix was back online after a program with a missing semicolon brought down their website in 2008. As well as Netflix, they realized they were having a hard time scaling their business. Netflix grew quickly, but didn’t build data centers as fast as it could. As a result, their growth began to stagnate.
Netflix, therefore, gradually switched from monolithic to microservice architecture in 2009. Having adopted it in December 2011, Netflix has gone to a microservice architecture. As a result, Netflix has now gone from a monolithic application to hundreds of microservices as a result of this drastic step. According to Netflix, their microservice architecture was able to handle 2 billion API requests daily back in December 2015.
At the beginning of the 2000s, Amazon was experiencing a lot of issues, which affect. As a result, the company quickly realized that this was not a sustainable model. As a result, they moved to microservices, where each service has a single function, accessible via web service APIs.
Amazon was successful in their planning as they moved to microservices architecture
After knowing how large companies have implemented the microservice architecture pattern with lightning speed, let’s move on to the best practices to use while implementing the pattern.
Uber started out as a monolithic organization, as did other startups. Company founders found it simpler to provide UberBLACK services only. Developers chose to use multiple languages and frameworks when the startup grew rapidly, so they decided to switch to microservices. With over 1,300 microservices, Uber is now better able to scale their apps.
To facilitate synchronization, Spotify’s founders designed a system with independent components scalable independently. As a result, for Spotify, the main advantage of microservices is their ability to prevent catastrophic failures. There will be no impact on users even if multiple services go down at the same time.
If you plan to implement microservices architecture in your next project, you should keep in mind the following considerations:
As a comparison to monolithic architecture, microservice architecture design and implementation is not an easy task. However, for the development process of mobile apps, microservices are very useful and handy. Enterprises with large amounts of complexity and a desire to compete on an equal playing field must embrace microservice architecture. Therefore, developing mobile apps with microservices can have long-term benefits for startups and small businesses. In the early days of microservices architecture, early adopters like Amazon, Twitter, and Netflix achieved success. Now, it your turn! Contact us and we shall surely help you!
