Docker: The Why’s and How-to’s on Alibaba Cloud

Cloud computing has brought about an upgrade and a paradigm shift over the traditional methods of hosting, deployment, and usage of applications. Since the dawn of DevOps, Alibaba Cloud has continued its development phase to keep up with the industry practices and trends and to set new industry standards and practices.

The DevOps lifecycle depends on automation alongside good infrastructure and microservices. These microservices are a collection of services that can be configured, reused, and independently maintained. Here comes the need for a container service, as it can leverage the true potential of microservices to provide a more scalable and reliable system.

Alibaba Cloud introduced its container service that provides an option to use either Docker or Kubernetes to manage and maintain your containerized applications.

The Container Service is a high-performance engine that is highly scalable. It sources a simplified architecture to maintain container management clusters. With the Alibaba Cloud container service, you get the integrated support of virtualization, network, security, and storage. This creates the most optimal solution for you to deploy your containerized applications on the cloud. With microservices support, the container service is the most dependable resource for you on the cloud.

DevOps and Alibaba Cloud have grown to define many industry practices and set multiple standards of operations and delivery. In this article, we will discuss, what Docker is, how it works with Alibaba Cloud, and how you can utilize it.

Docker is an open-source platform for administrators and developers that was built by developers. It has been designed to build, run, and share containerized applications.

Why Use Docker on Alibaba Cloud?

Docker uses containers. It is a highly supported and lightweight tool that gets your work done with ease. Why should I use Docker instead of Kubernetes? We will answer that question, but first:

Let’s discuss the basic advantages of using containers:

  1. When an application is put in containers, it increases the flexibility of that application. Even the most complex applications can be containerized to make them more available and easier to maintain.
  2. DevOps Containers are extremely lightweight since they use the host kernel to leverage system resources and Virtual Machine (VMs).
  3. Integration with cloud services enables a much portable architecture of build, deploy, and run anywhere.
  4. Containers have an architecture that is loosely coupled. As a developer, you can modify one and the others around it will not be affected. This enables easy upgradation or replacement, if necessary.
  5. Containers are self-sufficient and highly secure. Since they are isolated and no additional configuration is required from the user, it makes containerized applications ideal for meeting various security standards.
  6. If and when a datacenter provisions more resources, containers can be replicated and automatically distributed to meet demand.
  7. DevOps implementation using Docker and Alibaba Container Service enables a smooth and reliable solution that has support from many sub-serving solutions.

Docker swarm is used to cluster, schedule, and orchestrate environments that are running on multiple containers with Docker. If you are not running a virtual machine, you don’t need to depend on the hypervisor, all you need to do is implement Docker over the Infrastructure and Operating system that are provided by Alibaba Cloud and you are good to go.
