Introduction of Docker Container Technologies Benefits for Microsoft Azure
In fact, the development in cloud computing with SDN & NFV technologies reveals the secret of its power. Due to the rapid growth of these two technologies, organizations now can achieve the real benefits of IT infrastructure deployment by means of storage and networks automation, flexibility, virtualization and the most important is orchestration.
Dockers, along with SDN & NFV,are the composition of recently released orchestration tool kit that can make sophisticated and comprehensive multi-container applications to provide ease in organization IT routine operations. The three orchestration tools are Docker Machine, Docker Swarm and Docker Compose.
Docker Machine tool is the combination of host and client. The tool used to create Docker hosts on computer (either located at cloud provider’s premises or private data center) along with Docker client. We can manage Docker host to start, inspect, stop, restart, and use to manage Docker client and daemon.
As Docker runs on Linux, every VM of Docker Machine trusts on a base operating system, there are default base operating systems to ease the configuration as per requirement, i.e. for example, the drivers used to connect to cloud providers, the base operating system will be Ubuntu 12.04+. It can be variable while creating the machine.
It’s a native clustering option in Docker. It allows to create and access pool of Docker hosts with the help of complete set of Docker tools. As Docker Swarm uses by the Docker API, following are some tools in support of Docker daemon using swarm:
- Docker Compose
Prerequisites of creating Swarm
For creating Swarm,First requirement is to install virtual box. There is no need to install as a separate tool in Microsoft Windows Azure or Mac OS X, as both have Docker installed.
To pull the Docker Swarm Image, we create a swarm on network and with the help using Docker, we configure the swarm manager and all the nodes to run Docker Swarm with the following method:
- Opening a TCP port on every node for communication with the swarm manager.
- Install Docker on all machines
- Create and manage TLS certificates for security of swarm
Docker’s compose tool is used to maintain logical definition of application containers and the links between them.
Why YES to Containers NO to Hyper-visors
Indeed the Docker container is a smart way for development team to build applications to grow business through IT in a quick and efficient way. It enables developer and IT professional to deploy applications on hosts within few seconds.
Docker plays remarkable role in application development by considering it as a complete new level; it makes possible to get far more apps running and very easy to package and ship programs.
As Virtual machines or Hyper-visors, such as Hyper-V, KVM or Xen, simulates the complete hardware into software, so we can say that they’re resource hungry in terms of system requirements.
Whereas Containers used shared operating systems, so we can say there is no doubt that it is much more efficient as compare to hyper-visors.
Deploying container with Azure- It’s simple!
Here is an example of getting started with Azure, there are many container applications to work with, not limited with mango ,postgres or redis .
Docker’s beauty is, we can say making an application package by wrap up with a piece of software which includes entire dependencies, and make it capable as a standardized unit for software development i.e. code, run time, system tools, system libraries;Docker configuration with Azure such as Ghost, mysql or Jenkins with Microsoft open volume licensing program provide us the robust development tools.
