microservices pros and cons

12 Dec microservices pros and cons

A monolithic architecture puts all its functionality into a single unit, like a train – you can add more train cars, but it is a single train. You can also use Docker Compose to run multi-container applications. Unlike monolithic applications, the microservices architecture can gracefully handle spikes in users and resources. The opposite of microservices is “monolithic” application architecture that is characterized by a single service or process that handles all application responsibilities – a software architecture commonly used to initially build information technology (IT) infrastructure for many, if not most organizations. In the ever-expanding world of software engineering buzzwords, “microservices” are a fairly recent addition. Enterprises can expect a variety of benefits when they transition to a microservices-oriented application architecture. As with any technology, there are pros and cons associated with microservices. By Rory MacDonald on 11th June 2015 Software Architecture Software Development A microservice is a small networked service, that has specific responsibilities and an externally accessible API … The most interesting question, however, is how microservices compare to monolithic applications. But what are microservices and what are the pros and cons of adopting them? Kubernetes was created by Google and, it’s the most popular orchestration platform at the moment. Let’s take a look at some of the pros and cons of microservices. Microservices are a popular software design architecture that breaks apart monolithic systems. This is great for companies who already use these methods. You can read more about the SOA vs microservices debate in this article by IBM DeveloperWorks. Mainly, because they come with a couple of benefits that are super useful in the era of containerization and cloud computing. Below, you can see an illustration from the Docker blog about how to use Docker Swarm and Compose together to manage container clusters: You won’t need a container orchestration tool in the case of a smaller app. Applications are built as collections of loosely coupled services. The Advantages of Microservices. However, it is a big step: some organizations have already struggled with Agile and DevOps adoption: microservices are an even bigger challenge. Microservices are the most suitable for large-scale applications. There are a couple of microservice frameworks for the Java platform you can use, such as: Using Spring Boot is the most popular way to build microservices in Java. It uses Spring, Spring Boot, and Spring Cloud to build the application. Both allow you to deploy containers to a cluster of computers instead of just one machine. While these compartments are ideal for cloud-based deployments, developers must carefully weigh microservices pros and cons before deployment. ), Easier to create a CI/CD pipeline for single-responsibility services, Doesn’t work without the proper corporate culture (, Isolated services have better fault tolerance, Security issues (harder to maintain transaction safety, distributed communication goes wrong more likely, etc. Microservices: Pros & Cons of Using Microservices On A Project. Read our privacy policy. As microservices are well-isolated, they can be tested, deployed, and versioned individually. You have different options to structure microservices in Docker. Applications composed of microservices scale better, as you can scale them separately, whenever it’s necessary. Microservices Pros and Cons Pros of Microservice Arcitecture. It is easy to scale out by deploying each service independently, creating instances of these services across servers/virtual machines/containers. You can read the detailed analysis of their approach on The New Stack. Maintaining and monitoring microservices is an important part of microservices. From a software developer’s perspective, these pros and cons include: Cloud providers become experts at addressing these problems to unleash the value to organizations, including: As businesses struggle to meet the demand to automate data services to achieve efficiencies in business and to better handle the increasing complexity and communication requirements of a growing number of applications, wearables, and the Internet of Things into the overall picture, microservices will provide the flexibility, scalability and cost-efficiency needed to future-proof their IT infrastructure, RT @CBCHereandNow: MAJOR DONATION ALERT: @markbarrenechea CEO of @OpenText just announced a $100,000 donation to our Sounds of the Season f…, What an incredible day! Some developers emphasize their similarity and consider microservices as a subtype of SOA. From a software developer’s perspective, these pros and cons include: Pros. ), Large choice of programming languages, operating system, database technologies, Built-in tools such as Docker and Kubernetes. However, the adoption of these extra requirements can be a challenge for smaller companies. Microservices Architecture Advantages and Disadvantages. Popular cloud platforms come with several microservice-friendly features, such as: Microservices in the cloud are usually deployed in containers, as that’s how you can make the most out of the infrastructure. Microservices can offer substantial advantages to your business, including an increase in agility, security, transparency, scalability, and predictability. Microservices provide a new paradigm for software developers, allowing them to develop complex enterprise applications as a series of related functional compartments. Although SOA has no official standards, principles defined in Thomas Erl’s book entitled “SOA: Principles of Service Design” are often used as rules of thumb. Communication between microservices can mean poorer performance, as sending messages back and forth comes with a certain overhead. We’ll only briefly take a look at the application structure. Applying microservices means to compose an application out of independent services running in separate processes. ), Standardized service contract (services follow a standardized description), Service abstraction (services hide their internal logic), Service reusability (service structure is planned according to the DRY principle), Service autonomy (services internally control their own logic), Service statelessness (services don’t persist state from former requests), Service discoverability (services come with discoverable metadata and/or a service registry), Service composability (services can be used together), Create the service registration (so that microservices can find each other), using the Eureka registration server (incorporated in Spring Cloud), Create an account management microservice called “Account Service” with Spring Boot, Create a web service to access the microservice, using Spring’s, Managed services (e.g. There is no easy way to identify which form of architecture will work best for your team – it’s important to assess all the advantages and disadvantages that come with both monoliths and microservices, as well as common pain-points. It typically consists of four major components: a user interface, business logic, a data interface and a database. © Copyright 2020 OpenText Corp. All Rights Reserved. However, that does not entirely rule out the presence of cons, which though minor and easy to mitigate, should also be listed. Spring Boot is a great tool to build microservices in Java, however, you can use other frameworks as well. Building and maintaining monolithic systems is becoming increasingly difficult. Besides, containers are isolated, run anywhere, and create a predictable environment. Here are some other great articles (with example code), too: Containerization is one of the biggest trends in the dev world right now. Or, at least a part of it. Last month, we talked about the increasing popularity of adopting microservices in application development. Evaluate Weigh the pros and cons of technologies, products and projects you are considering. With Docker Compose, you can configure your app’s microservices using a YAML file. Although the latter solution is less common, sometimes it’s the better choice. This allows teams to choose an appropriate tool for the job, some languages and libraries are better suited for certain kinds of problems. This should help us explain how we, at Good Rebels, determine which form of architecture is right for a team or organisation. Microservices: Pros and Cons of Mono Repos When putting a system together, you need to decide whether you're going to keep the code in one repository or split it across multiple repos. Best 5 Pros and Cons of Microservices Explained. Below we will discuss the most common advantages and disadvantages of microservices architecture in an enterprise environment. Advantages and Disadvantages of using Microservices Architecture in Applications . You need to introduce DevOps tools such as CI/CD servers, configuration management platforms, and APM tools to manage the network. This means more agility, too. Spring Boot is a utility built on top of the Spring platform. Microservices are a modularization approach. It seems as if the whole world of software development is jumping on the bandwagon to move to a microservices architecture. When considering what microservices are particularly well-suited for, the following advantages and disadvantages should be taken into account: Microservices pros: Let's examine the pros and cons of monolithic vs. microservices architecture. The difference in the way that the two architectures work is simple. GraphQL Pros and Cons: advantages and disadvantages compared to REST, architecture, core features, tools, and ecosystem. However, you might want to automate container management when you deal with several microservices. Microservices offers the freedom to independently develop and deploy services (when you need a metaphorical “forklift,” you can add it to your fleet of “cars” and “trucks”) The services typically expose their functionality through a REST API and exchange HTTP messages to interact. For instance, while independent microservices have better fault tolerance than monolithic applications, the network has worse. Container platforms, DevOps practices, and cloud computing can help a lot in adopting the microservices architecture. Be alerted to issues affecting end users and replicate problems 1,000x faster than using logs and incomplete information from users. Docker Swarm is embedded in the Docker Engine; it’s Docker’s native orchestration tool. ), Faster development cycles (easier deployment and debugging), Harder to maintain the network (has less fault tolerance, needs more load balancing, etc. However, if you want to create a complex, multi-functional app, microservices are the better choice. Let’s say a team is joining a project to introduce a new … While GraphQL is the right solution for multiple microservices, you’d better go for REST architecture in case of a simple app. Microservices have become hugely popular in recent years. Moving to a Microservices Architecture After reviewing the pros and cons of monolithic and microservices architectures in part one of this series, it’s time to talk about whether or not you should switch to a microservices architecture. It’s easier to maintain and debug a lightweight microservice than a complex application, after all. Docker, being the most popular containerization platform, is an excellent tool to build microservices. After all, they need to manage the whole lifecycle of the microservice, from start to end. Microservices Pros and Cons; Pros Cons; Focuses on single business capability: Difficult to coordinate teams: Freedom to use different technologies: Creates troubleshooting challenges: Supports individual deployable units: Increases configuration/operation efforts: Small attack surface: Hard to track data across services As companies grow and business processes change, more demands are placed on IT to handle an increasing volume and velocity of data to better manage business functions – everything from raw materials orders to production to sales to invoicing to distribution. Discussion of technical diversity often centers on best tool for the job, but often the biggest benefit of microservices is the more prosaic i… Rao Uppala . Microservices follow the principles of service-oriented architecture (SOA) design. Feature image credit: Western Oregon University. The microservices pros and cons vary for each type, however, there are a few common characteristics that make this architecture an ideal solution to modern development problems. So, let’s have a closer look at their pros and cons. Within a service you can use anytechnology and infrastructure. Microservices work well with agile development processes and satisfy the increasing need for a more fluid flow of information. https://t.co/Yzn8SsX0fE #ai… https://t.co/h3LEtHqVIj, PRESS RELEASE: OpenText Announces $1M USD Donation to Fight Food Insecurity “The demand for food banks has never be… https://t.co/RxCVKLX1Y0, We'll be listening 🎅🎄🎅 https://t.co/LnlKICVJ1m. Therefore microservices can be independently deployed. Others rather stress their differences and claim that each solves a different set of problems. .NET Monolithic Applications vs Microservices: Pros and Cons. According to the latter view, SOA has an enterprise scope while microservices have an application scope. Microservices are increasingly popular but sometimes a monolithic application is the best choice. Pros: Smaller and … Topic: Microservices with Microsoft ASP.NET Core .  A microservices architecture enables scalable, adaptable, modular, and quickly accessible cloud-based applications and services and provides the dynamic, consistent experience that today’s global businesses require. In most cases, the size and complexity of the app you want to develop should determine its architecture. Communication can be hard without using automation and advanced methodologies such as Agile. Microservices. To recap the main points, here are the pros and cons of microservices compared to monolithic applications: Java is one of the best languages to develop microservices. Monolithic architecture. Within the enterprise scope, apps communicate with each other. The pros and cons of the microservices architecture are: Pros of Microservices: Scalability: Microservices applications are tremendously scalable, since each component can be scaled independently of the rest. For some organizations, microservices enable the agility that modern software development needs. Microservices architecture is designed to accommodate the need for large application development by providing a suite of modular components and services. For instance, here’s a very simple microservices example by Paul Chapman, published in detail in the official Spring blog. Microservices Software systems are growing in complexity these days. The monolithic architecture is easier to develop as it doesn’t require a diverse technology stack and is frequently limited to several commonly used frameworks or programming languages. In the world of software buzzwords, “microservices” began appearing regularly around 2012. It can save a lot of time by automatically configuring Spring and third-party libraries. In this article, we will look at the pros and cons of microservices and monoliths. Contrarily, in a monolith all components run in the same process and infrastructure (typically an applica… While it’s easier to develop and maintain independent microservices, network management requires additional efforts. Although SOA and microservices follow similar principles, their relationship is often debated. Because you can deploy each independent service on its own, it takes less time to develop updates for your application. Microservices use APIs and communication protocols to interact with each other, but they don’t rely on each other otherwise. Innovation Through Polyglot Programming. Raygun APM, Real User Monitoring and Crash Reporting are designed with modern development practices in mind. With a system composed of multiple, collaborating services, we can decide to use differenttechnologies inside each one. As with any technology, there are pros and cons associated with microservices. I won’t include code examples here, as you can find them in the original article.  SOA is an approach for designing how you want the world to interact with your business, and microservices are the fractal engines that your customers don’t see (customer-facing services are implemented with smaller ones which rely on smaller ones – fractal). Although microservices bears a similarity to service-oriented architecture (SOA) – both contain “service” and “architecture” in their name – SOA is like the way a customer sees your web site, and microservices is more like the wiring inside your web site. Mahipal Nehra. You can develop and deploy each microservice on a different platform, using different programming languages and developer tools. Introduced around 2012, it has steadily gained in popularity. Average rating: (3.88, 25 ratings) Watch the keynote. The best software performance articles from around the web delivered to your inbox each week. It makes it possible to set up stand-alone Spring apps with minimal configuration. What we gain on the simplicity of single-responsibility microservices, lose on the complexity of the network. They interact with each other through communication protocols such as HTTP and TCP. The difficulty with a monolithic architecture is that frequent and continuous changes are difficult to implement while maintaining ongoing and optimal business operations.  A microservices architecture organizes its functionality into smaller units, like a fleet of cars and trucks – to make more things happen, you can add more independent cars and trucks. The Cons. This kind of single-responsibility leads to other benefits as well. Learn how to leverage it. It is another approach to separate a big system into separate smaller services and each can interact with each other. The steps are as follows: Here’s an illustration of the app’s structure (also from the Spring blog): Of course, this is a very simple example. In this post, I explore the pros and cons of microservices to help you decide whether to embrace this trendy software architecture style or swat it away. introducing “serverless” does not break your architecture, but instead provides you even more flexibility), The code is organized around business capabilities (anything from add_a_customer to read_from_a_database), Spins up and down more quickly (when you need another “car” you can have one in moments, no need to go to the “dealership” to get one), When change is required in a certain part of the application, only the related service is modified and redeployed (no need to modify and redeploy the entire application), Easy to scale and integrate with third-party services, No long-term commitment to a technology stack, Distributed deployment and process flows can create complicated testing, Increasing number of services can result in information barriers, The architecture brings additional complexity as the developers must implement fault tolerance, mitigate network latency, and deal with a variety of message formats as well as load balancing, In addition to several complexities of an existing monolithic architecture, the developers have to deal with the additional complexity of a distributed system, Handling use cases that span more than one service without using distributed transactions is not only tough but also requires communication and cooperation between different teams, Partitioning the application into microservices is very much an art, Because each microservice can be developed and deployed independently, applications can be up and running quickly, A microservices platform offers an agility that monolithic systems do not, which enables businesses to add new functions or update existing features easily and in shorter timeframes, Microservices architecture reduces infrastructure costs and mitigates the risk of capacity-related service outages, Scheduled downtimes are reduced because microservices can be updated independently, Services can grow or shrink as the business scope changes. Most importantly, coders can focus on individual services which are relevant to the business goals they are currently focusing on The traditional monolithic approach works fine for smaller-scale applications. Each microservice is responsible for a single feature. Many industry leaders like Amazon, Twitter, PayPal, The Guardian, and Netflix have already successfully switched from monolith to microservices. You can deploy each microservice in its own Docker container,read more on how Docker works You can also break down a microservice into various processes and run each in a separate container. Today we announced the OpenText #VoyagerFund, and a $1m donation to food banks around the w… https://t.co/hKuyk53Zju, Is 99 percent of your business data unused? Rachel Laycock (ThoughtWorks), Cassandra Shum (ThoughtWorks) 9:30–9:50 Thursday, 20/10/2016 Location: King's Suite. Breaking Down the Monolith Pros. As microservices heavily rely on messaging, they can face certain problems. Microservices also reduce the time to market and speed up your CI/CD pipeline. Global testing becomes slightly more complicated with Microservices since the … This allows us to pick the right tool for each job, rather thanhaving to select a more standardized, one-size-fits-all approach that often ends up beingthe lowest common denominator. Microservices are frequently run as cloud applications, as they are lightweight and easy to scale and deploy. The two most popular tools are Docker Swarm and Kubernetes. Microservices, also known as microservice architecture, isn’t something that you must dive into immediately—but it’s also not something you should ignore. The Pros and Cons of Microservices Microservices: Benefits Shorter Development Time. Microservices may be a hot trend, but the architecture does have drawbacks. Development is performed with one directory and deployed fast on the server after testing. Why Join Become a member Login microservice frameworks for the Java platform, Currency conversion microservice with Spring Boot, how to deploy microservices with Docker and Docker Compose, how to use Docker Swarm and Compose together, Raygun APM, Real User Monitoring and Crash Reporting, Best practices for tracing and debugging microservices [2020], Server performance metrics: 8 you should be considering, Needs more collaboration (each team has to cover the whole microservice lifecycle), Poorer performance, as microservices need to communicate (network latency, message processing, etc. The biggest pro of microservices architecture is that teams can develop, maintain, and deploy each microservice independently. Redwerk. And, while teams can choose which programming language and platform they want to use, they also need to collaborate much better. In general, the main negative of microservices is the complexity that any distributed system has. Clarity – With a simple modular structure, microservices are far easier to manage and understand. AltexSoft. Monolithic vs Microservice Architecture- Pros and Cons. The pros of microservices are quite substantial. It can save you a lot of time, as you don’t have to create and start each container separately. See how the Raygun platform can help keep your containers performant.
