Physical network topology is the placement of the various components of a network and the different connectors usually represent the physical network cables, and the nodes represents usually the physical network devices (like switches). Logical network topology illustrates, at a higher level, how data flows within a network.

Logical diagram vs physical diagram. Conversely, a physical data flow diagram shows how the system will be implemented, including the hardware, software, files, and people involved in the system. The chart shown below contrasts the features of logical and physical models. Notice that the logical model reflects the business, whereas the physical model depicts the system. The logical view decomposes the functionality into a network of communicating components. Typically, the collaboration between the components realizes the black-box behavior speci ed ... diagrams, message sequence charts, component diagrams and statecharts.

Data Flow Diagram (DFD) explains the flow of data of an information system. There are two types as Logical DFD and Physical DFD. Logical DFD provides an insight into what the system is while Physical DFD defines ... The physical vs. logical network diagram distinction can be boiled down to a difference in scope. A physical network diagram depicts the network topology with the physical aspects like ports, cables, racks, and more. A logical network diagram, on the other hand, shows the "invisible" elements and connections flowing through the physical ...

A logical DFD focuses on the business and business activities, while a physical DFD looks at how a system is implemented. So while any data flow diagram maps out the flow of information for a process or system, the logical diagram provides the "what" and the physical provides the "how.". They are two different perspectives on the same ... The main difference is that with the physical diagram, it is the tangible diagram you create, for example, the layout of the devices, racks and so on.

What are the differences between logical and physical network diagrams? Logical Network Diagrams. A logical network diagram describes how information flows through a network. Logical diagrams typically show subnets (including VLAN IDs, masks, and addresses), routers, firewalls, and its routing protocols. A network diagram can be either physical or logical. Logical network diagrams. A logical network diagram describes the way information flows through a network. Therefore, logical network diagrams typically show subnets (including VLAN IDs, masks, and addresses), network devices like routers and firewalls, and routing protocols. A logical network diagram usually shows network devices like routers, firewalls, and voice gateways. A physical network diagram shows how the network devices are physically connected together, and therefor all ports on all devices on the network are represented here. This will include cables. Logical architecture is a structural design that gives as much detail as possible without constraining the architecture to a particular technology or environment. For example, a diagram that illustrates the relationship between software components. Physical architecture gives enough detail to implement the architecture on a technology.

The logical diagram that shows four computers, in this case, would reflect only a single computer in a physical diagram. Networks that use VLANs or VPNs often have radical differences between their logical topologies and their physical topologies. Several remote sites "connected" via VPNs appear, logically, to be connected to each other with ...

In short, the logical architecture of microservices doesn't always have to coincide with the physical deployment architecture. In this guide, whenever we mention a microservice, we mean a business or logical microservice that could map to one or more (physical) services. In most cases, this will be a single service, but it might be more.
