Microservice Architecture is a software design pattern that structures an application as a collection of loosely coupled services rather than one monolithic application. A microservice architecture makes it easier to implement large-scale applications by allowing you to break down a large application into smaller components, which can be designed and developed by smaller teams. Microservice architecture fosters application portability and agility. Because different teams are responsible for different services, more of the application can be changed at any time.
What is Microservices Architecture?
Microservices architecture is a new approach to designing applications. It emerged in the early 2010s as a response to the growing popularity of microservices as a method of scaling out applications in an effort to integrate multiple product lines from the same company. By embracing and mimicking agile development methodologies, the microservices architecture, originally designed for software as a service (SaaS) applications, has been applied successfully to traditional, relational enterprise applications as well. According to a survey conducted in 2017 by CollabNet, the adoption of microservices architecture in the enterprise is still in its infancy. Only 4.9% of respondents reported that their organizations are running a microservices architecture at present, while 70.
Advantages of Microservices Architecture
Every service has a purpose Single service can be replaced with another Applications are easier to deploy Microservice Architecture is DevOps With a small team, it’s easy to operate. It allows you to scale quickly. It offers quick responses to issues Automation comes standard with microservices Is a manageable architectural pattern Is very flexible Easier to test and deploy Less prone to errors Allows you to modularize your code Often cost-effective Microservice Architecture Simplifies Maintaining Your Application There are thousands of things that can go wrong with your app, so your developers need all the tools they can get their hands on.
Disadvantages of Microservices Architecture
There are several downsides to microservice architecture, and they are not as much of a problem with monoliths as they are with microservices. The biggest disadvantages are: Misconceptions about how services are created. Developers often don’t understand how services are built. When services are created through libraries and it is understood how the libraries work, the development process is simplified. However, when a company chooses to move to a microservice architecture, it is not obvious how to build the services. The developer teams must either rely on the libraries or have to learn how to build the services themselves. Developers don’t have the authority to shut down services.
How to implement a Microservices architecture
One of the biggest benefits of implementing microservices architecture is the ability to support application design and evolution from a small team. Since each service can be written using any language or framework, you can choose the tools that are best suited to the functionality that you want to expose to your users. Microservice architecture can also help scale the application, as services are made smaller and components can be reused more easily to keep the application as small as possible.
Microservices and Continuous Integration
Many large projects have struggled to build large applications and push them into production because of the challenges involved with developing the application and releasing it to production. In some ways, the monolithic application was easier to develop, maintain, and deliver. However, this approach increased the risk of delivering late and broke the entire team when it was too late to respond to issues in the system. Monolithic applications are only fully effective when they’re first deployed to production. As soon as the team is happy with the application and the platform, it has to start from scratch to implement the next feature.
Microservices and Continuous Deployment
Migrating to a microservice architecture is a huge improvement for developers because microservices permit them to easily deploy and upgrade components to new platforms. Here’s why. Continuous Delivery Continuous delivery is a methodology that guarantees that a software update or application patch is available to customers at all times. The idea behind continuous delivery is that software updates should be available to customers at all times or at the very least within a defined amount of time. Often times, the idea of continuous delivery is associated with migrating to a microservices architecture. The initial thought is that it is hard to integrate more than a few services. However, the idea of continuous delivery has nothing to do with different teams working on different services.
How to make a Microservices Architecture scalable
One of the main goals of developing a microservice architecture is to make sure that your applications remain scalable. When you break up your applications, your number of services does not necessarily need to decrease. In fact, you may want to increase the number of services, if your application needs more power and scalability. To increase the scale of a microservice architecture you will need to increase the number of operations your services are capable of running. For instance, if your application needs to process 10,000 transactions per second, then you can’t have five services doing the same thing. You’ll need 10,000 independent services. This scale is usually achieved by having multiple microservices in your architecture that communicate with each other through a message queue.
What is a good testing strategy for Microservice architecture?
Every team should develop a test strategy that aligns with their agile development methodology. When a team has a robust test strategy in place, its members can more easily identify and solve problems as they arise. When things go wrong, everyone involved can quickly identify and solve the problem. Docker (and Kubernetes) For many teams, Docker is a critical piece of the Microservice architectural puzzle. Using Docker helps companies be more agile because it helps the teams be more portable. Another advantage of using Docker is that it allows teams to do more testing easily and quickly. Other teams, however, don’t want to use Docker because of the downtime involved when Docker stops working. That’s why Kubernetes is becoming a popular choice for microservices architecture teams.
The combination of RESTful web services and microservices makes this an interesting application design pattern for MVC web applications. It introduces a new way for a web application to process a user’s request. It improves the responsiveness of the user experience because the response times will be less dependent on the complexity of the application. This application is an interesting use of Microservice Architecture. It’s another one of those cool-looking applications that you only see in movies. It even has a Twitter icon to signify that it’s a Twitter application. It’s really difficult to get lost in an application like this. There are all kinds of interesting connections with Web Services and RESTful APIs. Â This is just a first step in a long journey.
All this has made microservice architecture extremely popular in recent years. With more than 25% of all new applications being built with microservices, the business value it brings has finally begun to be appreciated. While all this talk of microservices is a real breakthrough, there are still some missing elements in the architecture that need to be addressed: Modular and Maintainable Services. While many successful microservices are designed in a functional programming style, the majority are implemented in object-oriented languages. This shows that we still need to work on the design and maintenance of services in order to avoid a few big bugs in the pipeline. In other words, there are a lot of little things that need to be improved in the design. Time to Market.
