Abstract
Before delving into methods to implement microservice architecture and AWS, one has a basic understanding of microservices. We can consider them as an essential approach to software development, innovation, and scalability. Why are they used? Developers can use the agile approach and work independently. Services can be managed by small teams, and this is essential to scale any service.
While creating a microservice, a customer expects the following things.
- API-driven Approach.
- Event-driven Approach.
- Data Streaming.
We are going to cover all the approaches and will show important details of microservices. The motto is to overcome the development challenges and leverage AWS. We will also show how Amazon Web Services are to be utilized to overcome the obstacles.
Introduction
Microservices are not a new approach to software boxes development. Why are they gaining popularity? They are a combination of the following concepts.
- Flexible software development techniques.
- SOA or service-oriented architecture.
- API-based models or designs.
- Constant delivery and innovation.
And what are the considerations for design? Let’s discuss everything in detail and learn more about microservices.
We have to focus on scalable and tolerant-resistant microservice architecture. Further, we will include user interface and data storage. Amazon web services leveraging containers have to be built. Then, AWS is used to implement the serverless microservice architecture, reducing complexity.
Below are some tenets that define a serverless model.
- No infrastructure.
- Self Scaling.
- Billing Model.
- Fault Resistant.
- Built-in Structure.
Lastly, we look at the system and discuss the functional aspects of microservice architecture. For example, monitoring, communication and data consistency.
Microservice Architecture and AWS
Different layers are used to build monolithic apps, including the user interface. But the structure of monolithic apps is different from that of microservices. Microservice architecture splits functions into different layers.
A. User Interface
Modern apps using JavaScript framework can communicate to REST or RESTful APIs. Amazon storage services are used for static content.
Since proxy servers or caches respond to microservices, the case of latency becomes reduced. However, CDN does not have any effect on microservices running close to each other. It would be better to implement other types of catching mechanisms, as it is the best way to reduce latency.
B. Microservices
APIs are an important component of microservices. Application logics are based on programming interfaces. For example, RESTful web services API. They will accept calls, process them and implement different functions. For example, authentification, catching, routing, and authorization.
C. Implementation
AWS carrying building blocks plays an important role in the development process. There are two popular approaches – AWS Lambda and AWS Fargate (docker containers).
AWS Lambda will execute every function needed for the development, only you have to upload a piece of code. Even you do not need an administrator. Several programing languages can be supported and triggered directly through AWS services. All can be done through a web or mobile application. Look at the following benefits of using it.
- Easy shifting.
- Valuable business logic.
- Security.
- Scaling.
Thus it helps in the development of microservices.
Container-based deployment is one of the best methods of architecture. Docker is a container-technology that has many benefits. They are portable, efficient and productive. Learning curves with dockers are steep, and you do not need to worry about docker images and monitoring. Amazon ECS and Amazon EKS are easy to install, operate and can be used to scale the systems.
