Here we will give you a brief introduction to APIs and Microservices and also learn what are the Similarities
and the Difference between both.
Microservice
Microservices - also known as microservice architecture - is an architectural style that structures an application as a collection of services that are
Highly maintainable and testable
Loosely coupled
Independently deployable
Organized around business capabilities
Owned by a small team
The microservice architecture enables the rapid, frequent and reliable delivery of large, complex applications. It also enables an organization to evolve its technology stack. Microservices architectures make applications easier to scale and faster to develop, enabling innovation and accelerating time-to-market for new features.
Benefits of Microservices:
Modularity: It means dividing services into different modules with their own set of functionality and dependencies to make an application easy to develop, test, and understand. It reduces the complexities and difficulties businesses face with the monolithic software development approach.
Distributed Development: The microservices architecture streamlines the development process as smaller teams can be given the responsibility to develop, test, deploy, and grow services separately and in parallel.
Scalability: In microservices, a loosely coupled approach is implemented, separating the business logic, data access layer, and database. In contrast, microservices can be developed and deployed independently to perform their tasks and can be scaled easily. Due to precise scaling, you can scale only those components that you want.
Independent Deployment: Since the services are small and can be deployed independently, any change you make won’t affect the entire application. So, when you want to update a feature, you can take a microservice to directly start working on it and deploy it without redeploying the complete application.
Seamless Integration: With microservices, you can actually modernize your current monolithic application. This can be done using integrating legacy and heterogeneous systems. Microservices are also easy to integrate with many technologies and tools to help enhance your application’s features, functionality, and security.
Flexibility: Microservices provide you with better flexibility. You are free to use any tech stack with programming languages, libraries, frameworks, and other tools if supported for different components or services. Hence, you can build the latest and more advanced services to complement your application with the latest features and security features.
Security: Microservices architecture helps increase your application’s security. They are made to cope with compromises and failures. As various kinds of services communicate inside this architecture, a service can fail due to server issues, cyberattacks, etc. Even if one of the services fails, it won’t take down the entire application; the other parts will still perform as expected.
Simple Routing: Microservices follow a simple routing approach to receive requests and transmit responses accordingly. Microservices are developed with smart endpoints or clients that can seamlessly process information and apply business logic according to the requirements. However, other strategies like Enterprise Service Buses (ESBs) don’t do this. They utilize high-tech systems for applying business policies and message routing.
Increased Productivity: In a distributed development methodology where responsibilities are divided, it helps increase organizational productivity. A large task can be divided into smaller tasks that seem easily achievable with accuracy.
Easier Maintenance and Debugging: Creating smaller services is easier for developers to code and debug. They can analyze the overall services quickly to spot errors and issues in contrast to the scene when they had to analyze a massive application with all its dependencies and features.
Faster Time to Market: As a result of faster code development, testing, debugging, and deployment while ensuring quality, your time-to-market will be faster. You can take early feedback and improve your application faster instead of deploying everything at once. This will help you produce quality applications that customers love using.
APIs (Application Programming Interface)
API is the acronym for Application Programming Interface, which is a software intermediary that allows two applications to talk to each other. Each time you use an app like Facebook, send an instant message or check the weather on your phone, you’re using an API. APIs are needed to bring applications together in order to perform a designed function built around sharing data and executing pre-defined processes. They work as the middleman, allowing developers to build new programmatic interactions between the various applications people and businesses use on a daily basis.
Benefits of APIs
Speed: APIs offer incredible speed for various tasks for both businesses and users. They help accelerate operations to offer agility for businesses and reduce hassles for customers. For instance, if you want to order something online, you can directly go to your application and check whether the item is available or not.
Scalability: If you are a growing business, the first thing you must ensure is whether your tech stack is scalable or not. It will offer you the opportunity to grow your business with time. Using an API will give you tremendous flexibility and scalability to expand your products, increase the number of catalogs, manage increasing data, and handle growing security risks.
Security: Using APIs is a great way to enhance your application’s security. The reason is that when you make an API call, you are not directly connected to a web server. Instead, you are sending a small amount of data that the API delivers to the server and takes responses from the server. Hence, your application remains safe from attackers.
Increases Productivity: Using APIs will enable developers to implement more functionalities quickly. Instead of doing it from scratch. It will save a lot of time and effort for the business and developers who can dedicate time to innovation.
Reduces IT Cost: Building an application, however small or big, involves a significant investment. You will need technologies, tools, and people along with other resources to support your development process. But you can avoid all of them once by using a suitable API to build your application or enhance its functionality without spending a fortune.
Promotes Collaboration: Maintaining smooth and safe connectivity and communication has become troublesome for organizations due to increased security risks. But using private APIs can help boost communications and collaboration in your team or organization.
Boosts Innovation: Heavy competition across industry verticals has made innovation crucial for businesses. In addition, customer demands are changing, but companies must strive to meet those demands.
Improved Customer Experience: APIs are beneficial for end users as well. They help customers interact with businesses seamlessly and make them understand their challenges, preferences, and interests. In turn, businesses can take these inputs to work on them and improve their products and services while coming up with innovative solutions to meet their demands.
The Similarities:
Both are used in software development to accelerate development, testing, and deployment.
Both support cloud-based applications.
Both offer scalability to support your applications.
Both help to reduce expenses in software development by reducing complexities, the chance of errors, and risks.
Both provide security.
The Difference:
API | Microservices |
An API is an interface or an intermediary between two applications communicating with one another. It consists of functions and procedures to help consumers use an application’s underlying services. | Microservices architecture is a software development model that divides an application into smaller components or services. |
APIs are interface | Microservices are Components |
An API is a component of microservices that helps improve the effectiveness of microservices architecture. | Microservices are a complete architecture with multiple, smaller services |
It is large in size | It is small in size |
Takes long time to build | Takes small time to build |
APIs can be public, private, partner APIs, database APIs, REST APIs, remote APIs, SOAP APIs, and more. | Microservices are of two types: stateless and stateful microservices. |
