Benefits of Deploying Microservices Using Docker
Posted By : Dipshikha Bharali | 04-Jun-2020
Docker, the container orchestration tool, is becoming increasingly popular for microservice deployment because of its simple approach to reduce development complexities. Docker has made it easier to construct scalable and manageable container-based applications with microservices architecture. It is an OS-level virtualization tool that enables developers to segment applications into various containers. These containers (or microservices) can be loosely coupled with other containers, which serve as the foundation of the microservices application architecture.
At Oodles, we have gained extensive experience in cloud app development services. We specialize in building microservice-based applications and deploying them on cloud platforms like AWS, Azure, and GCP. Our development team is skilled at using Docker for deploying microservices on the cloud. In this blog post, we will explore the significance of microservices and enterprise benefits of using Docker.
What Are Microservices?
Microservices or microservice architecture is a form of service-oriented architecture (SOA) wherein applications are built as a collection of small autonomous services. It provides several benefits over the traditional monolithic codebase that is less scalable and less reusable. With a microservice architecture, developers can easily test, scale, deploy an application with the flexibility of using different programming languages, databases, and other tools for each microservice.
However, despite the many benefits over the monolithic applications, microservice deployment may become cumbersome in the absence of relevant tools. Each microservice is self-sufficient and can be developed in a wide range of programming languages. Since every language has its own libraries and frameworks, using multiple languages will require a completely different set of libraries and frameworks. As a result, cloud deployment becomes more complex, tedious, and time-consuming.
Using Docker technology, however, can easily overcome these challenges. Let’s discuss Docker and its significance in microservice deployment.
Docker To The Rescue
Docker is an open-source platform designed to automate building, deploying, scaling, and managing container-based applications. With Docker, developers can build high-quality applications and deploy them on the cloud quickly and more efficiently.
Developers use containers to pack an application with all its libraries and other dependencies in a single image and deploy it as a package. Docker and microservices often go hand-in-hand. We can divide large applications into separate containers, deploy them on the cloud, and manage them easily using Docker.
Benefits of Using Docker
Below are the main benefits of using Docker for deploying microservice-based applications on the cloud.
You can take any app configuration, put it into code, and deploy it without any problems. As it can be used in a wide variety of environments, the infrastructure requirements are no longer linked with the application architecture.
Docker accelerates the deployment of microservice-based applications by reducing complexities. It is due to the fact that Docker creates a container for every process and does not boot an OS. It can easily create and destroy data without impacting the process efficiency and without increasing the overhead costs.
Continuous Deployment and Testing
Docker maintains a consistent app environment from development to production. The containers are configured to maintain all configurations and dependencies internally. Consequently, we can use the same container from development to production with minimal discrepancies or mutual interventions.
Docker ensures that a separate container is created for each individual microservice. In addition, it ensures that each container has its own resources that are isolated from other containers. You can have various containers for separate applications running completely different tasks.
Multiple Coding Language
Docker supports multiple coding languages to make development quick, easy, and more flexible. Developers can bundle all services required to run a language, including its libraries and frameworks, into linked containers to easily manage multiple platforms.
Containerizing microservices is the best way to avoid the difficulties that developers often face while deploying and managing them. Using Docker is an effective solution for deploying containerized microservices on the cloud. The flexibility and simplicity that Docker provides is the main reason why it has become a preferred choice for microservice deployment and container orchestration.
