Automate storage with our Storage area networks change management primer Automation for virtualized environments For enterprises that have embraced virtualizationautomation and change management have become necessities. Virtualized environments purposely foster constant change that is not necessarily bound to specific physical hardware. Automation enables this provisioning based on events or schedules. For example, if an application delivery controller senses a rise in traffic to a Web application, it can ask the virtualized environment to spin up additional virtual machines to help handle the spike.
Overview Estimated reading time: Docker containers and services do not even need to be aware that they are deployed on Docker, or whether their peers are also Docker workloads or not. Whether your Docker hosts run Linux, Windows, or a mix of the two, you can use Docker to manage them in a platform-agnostic way.
This topic defines some basic Docker networking concepts and prepares you to design and deploy your applications to take full advantage of these capabilities.
Most of this content applies to all Docker installations. However, a few advanced features are only available to Docker EE customers.
Scope of this topic This topic does not go into OS-specific details about how Docker networks work, so you will not find information about how Docker manipulates iptables rules on Linux or how it manipulates routing rules on Windows servers, and you will not find detailed information about how Docker forms and encapsulates packets or handles encryption.
See Docker and iptables and Docker Reference Architecture: In addition, this topic does not provide any tutorials for how to create, manage, and use Docker networks. Each section includes links to relevant tutorials and command references. Several drivers exist by default, and provide core networking functionality: The default network driver.
Bridge networks are usually used when your applications run in standalone containers that need to communicate. See use the host network. Overlay networks connect multiple Docker daemons together and enable swarm services to communicate with each other.
You can also use overlay networks to facilitate communication between a swarm service and a standalone container, or between two standalone containers on different Docker daemons. This strategy removes the need to do OS-level routing between these containers.
Macvlan networks allow you to assign a MAC address to a container, making it appear as a physical device on your network. The Docker daemon routes traffic to containers by their MAC addresses. For this container, disable all networking.
Usually used in conjunction with a custom network driver. See disable container networking. You can install and use third-party network plugins with Docker. These plugins are available from Docker Store or from third-party vendors.Network security is not only concerned about the security of the computers at each end of the communication chain; however, it aims to ensure that the entire network is secure.
Network security entails protecting the usability, reliability, integrity, and safety of network and data. Overview of NetworkX ¶. NetworkX is a Python package for the creation, manipulation, and study of the structure, dynamics, and functions of complex networks.
