microservices pros and cons

But what are microservices and what are the pros and cons of adopting them? 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 If you are interested here’s a useful article by Linode on how to deploy microservices with Docker and Docker Compose. The traditional monolithic approach works fine for smaller-scale applications. Evaluate Weigh the pros and cons of technologies, products and projects you are considering. 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. They decided to skip Docker and containerization altogether to avoid extra overhead and complexity. The Pros and Cons. In most cases, the size and complexity of the app you want to develop should determine its architecture. 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. You can develop and deploy each microservice on a different platform, using different programming languages and developer tools. In the ever-expanding world of software engineering buzzwords, “microservices” are a fairly recent addition. As microservices are well-isolated, they can be tested, deployed, and versioned individually. Feature image credit: Western Oregon University. Microservices use APIs and communication protocols to interact with each other, but they don’t rely on each other otherwise. Each microservice is responsible for a single feature. 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. With a system composed of multiple, collaborating services, we can decide to use differenttechnologies inside each one. Mahipal Nehra. 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. Most importantly, coders can focus on individual services which are relevant to the business goals they are currently focusing on Spring Boot is a great tool to build microservices in Java, however, you can use other frameworks as well. Increasing growth and the need for an IT approach that can change quickly has led to increased adoption of a microservices architecture due to the ease of scaling operations to meet new demands. However, you might want to automate container management when you deal with several microservices. Microservices architecture is designed to accommodate the need for large application development by providing a suite of modular components and services. As microservices heavily rely on messaging, they can face certain problems. However, it’s also possible to deploy microservices in the cloud without using containers. However, that does not entirely rule out the presence of cons, which though minor and easy to mitigate, should also be listed. Let’s say a team is joining a project to introduce a new … .NET Monolithic Applications vs Microservices: Pros and Cons. Pros: Smaller and …  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). Kubernetes was created by Google and, it’s the most popular orchestration platform at the moment. Pros and Cons of Using Microservices in Applications . For some organizations, microservices enable the agility that modern software development needs. GraphQL Pros and Cons: advantages and disadvantages compared to REST, architecture, core features, tools, and ecosystem. Microservices work well with agile development processes and satisfy the increasing need for a more fluid flow of information. ... "Microservices" was premiered at an event for software architects in 2011, where the term was used to describe a style of architecture that many attendees were experimenting with at the time. Microservices Architecture Advantages and Disadvantages. After all, they need to manage the whole lifecycle of the microservice, from start to end. When considering what microservices are particularly well-suited for, the following advantages and disadvantages should be taken into account: Microservices pros: The services typically expose their functionality through a REST API and exchange HTTP messages to interact. Breaking Down the Monolith A monolith is built as a large system with a single code base and deployed as a single unit, usually behind a load balancer. In a monolithic system, all the components of the system are designed and packed into one single unit. 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. Last month, we talked about the increasing popularity of adopting microservices in application development. Microservices: Pros and cons. Monolithic vs Microservice Architecture- Pros and Cons. Innovation Through Polyglot Programming. This is great for companies who already use these methods. Microservices can offer substantial advantages to your business, including an increase in agility, security, transparency, scalability, and predictability. However, if you want to create a complex, multi-functional app, microservices are the better choice. Clarity – With a simple modular structure, microservices are far easier to manage and understand. Smaller apps are usually better off with a monolithic code base, though. Container platforms, DevOps practices, and cloud computing can help a lot in adopting the microservices architecture. You can also use Docker Compose to run multi-container applications. This allows teams to choose an appropriate tool for the job, some languages and libraries are better suited for certain kinds of problems. The Pros and Cons of Microservices Microservices: Benefits Shorter Development Time. Microservices are increasingly popular but sometimes a monolithic application is the best choice. While these compartments are ideal for cloud-based deployments, developers must carefully weigh microservices pros and cons before deployment. Let's examine the pros and cons of monolithic vs. microservices architecture. Read our privacy policy. The pros of microservices are quite substantial. ), Large choice of programming languages, operating system, database technologies, Built-in tools such as Docker and Kubernetes. They interact with each other through communication protocols such as HTTP and TCP. While it’s easier to develop and maintain independent microservices, network management requires additional efforts. Communication can be hard without using automation and advanced methodologies such as Agile. What we gain on the simplicity of single-responsibility microservices, lose on the complexity of the network. Maintaining and monitoring microservices is an important part of microservices. The difficulty with a monolithic architecture is that frequent and continuous changes are difficult to implement while maintaining ongoing and optimal business operations. Development is performed with one directory and deployed fast on the server after testing. Let’s take a look at some of the pros and cons of microservices. As with any technology, there are pros and cons associated with microservices. Contrarily, in a monolith all components run in the same process and infrastructure (typically an applica… Rachel Laycock (ThoughtWorks), Cassandra Shum (ThoughtWorks) 9:30–9:50 Thursday, 20/10/2016 Location: King's Suite. Applications are built as collections of loosely coupled services. Pros. ), Faster development cycles (easier deployment and debugging), Harder to maintain the network (has less fault tolerance, needs more load balancing, etc. Learn how to leverage it. You can read more about the SOA vs microservices debate in this article by IBM DeveloperWorks. Some developers emphasize their similarity and consider microservices as a subtype of SOA. This kind of single-responsibility leads to other benefits as well. Microservices Software systems are growing in complexity these days. However, the adoption of these extra requirements can be a challenge for smaller companies. Microservices are a modularization approach. This should help us explain how we, at Good Rebels, determine which form of architecture is right for a team or organisation. Besides, isolated services have a better failure tolerance. These are: Independent deployment and versioning. 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. 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. For instance, WeatherBug runs microservices directly on Amazon EC2, without using containers. If you have a large-scale application with several containers you can also make use of a container orchestration platform. Microservices provide a new paradigm for software developers, allowing them to develop complex enterprise applications as a series of related functional compartments.
