Amazon Web Services Diagrams diagramming tool for architecture

3-Tier Auto-scalable Web Application Architecture
Amazon Web Services (AWS) offers the reliable and relatively inexpensive cloud computing services. This is the main reason why many large companies prefer to use the Amazon Cloud to storage and operate the data. ConceptDraw PRO diagramming software enhanced with AWS Architecture Diagrams solution provides the powerful AWS diagramming tools to draw the Amazon architecture diagrams and Amazon Web Services planning diagrams, to develop the Architect infrastructure based on AWS in a few minutes. The AWS Architecture Diagrams solution offers variety of built-in samples and templates for several Amazon Web Services products and resources, a wide range of predesigned and recognizable vector graphic icons used for simple designing the Architecture diagrams. The diagrams created in ConceptDraw PRO are professional-looking, helpful when designing and implementing the AWS infrastructure based systems, useful to communicate design, deployment and topology, and apposite for using in presentations, whitepapers, datasheets, posters, and other technical materials you like.
This vector stencils library contains 184 round icons.
Use it to design cloud computing infographics and diagrams with ConceptDraw PRO software.
"Though service-oriented architecture advocates "everything as a service" (with the acronyms EaaS or XaaS or simply aas), cloud-computing providers offer their "services" according to different models, which happen to form a stack: infrastructure-, platform- and software-as-a-service.
Infrastructure as a service (IaaS)
In the most basic cloud-service model ... providers of IaaS offer computers — physical or (more often) virtual machines — and other resources. IaaS refers to online services that abstract the user from the details of infrastructure like physical computing resources, location, data partitioning, scaling, security, backup etc.
Platform as a service (PaaS)
PaaS vendors offer a development environment to application developers. The provider typically develops toolkit and standards for development and channels for distribution and payment. In the PaaS models, cloud providers deliver a computing platform, typically including operating system, programming-language execution environment, database, and web server. Application developers can develop and run their software solutions on a cloud platform without the cost and complexity of buying and managing the underlying hardware and software layers.
Software as a service (SaaS)
In the software as a service (SaaS) model, users gain access to application software and databases. Cloud providers manage the infrastructure and platforms that run the applications. SaaS is sometimes referred to as "on-demand software" and is usually priced on a pay-per-use basis or using a subscription fee.
In the SaaS model, cloud providers install and operate application software in the cloud and cloud users access the software from cloud clients. Cloud users do not manage the cloud infrastructure and platform where the application runs. This eliminates the need to install and run the application on the cloud user's own computers, which simplifies maintenance and support. Cloud applications differ from other applications in their scalability — which can be achieved by cloning tasks onto multiple virtual machines at run-time to meet changing work demand." [Cloud computing. Wikipedia]
The vector stencils library "Cloud round icons" is included in the Cloud Computing Diagrams solution from the Computer and Networks area of ConceptDraw Solution Park.

Personal area (PAN) networks. Computer and Network Examples

Personal area (PAN) networks. Computer and Network Examples
Personal area network (PAN) is a network organized on a limited area and used for data transmission between various personal devices, such as computers, tablets, laptops, telephones, different digital and mobile devices, etc. and also for connecting to higher level network and Internet. PAN is used to manage the interconnections of IT devices which surround a single user and generally contains such appliances, as cordless mice, keyboard, phone, and Bluetooth handsets. PANs can be wired with computer buses, or wirelessly connected to the Internet using such network technologies as Bluetooth, Z-Wave, ZigBee, IrDa, UWB, Body Area Network. PANs have a lot of pros and cons, they are expedient, lucrative and handy, but sometimes have bad connection with other networks on the same radio bands, Bluetooth has distance limits and slow data transfer speed, but is comparatively safe. ConceptDraw PRO diagramming software supplied with numerous solutions of Computer and Networks Area included to ConceptDraw Solution Park perfectly suits for designing the Personal Area Networks.
The vector stencils library "Application" contains 40 icons of software applications.
Use it to design your computer and telecom illustrations and infographics with ConceptDraw PRO diagramming and vector drawing software.
The vector stencils library "Application" is included in the Computers and Communications solution from the Illustration area of ConceptDraw Solution Park.

"Event partitioning is an easy-to-apply systems analysis technique that helps the analyst organize requirements for large systems into a collection of smaller, simpler, minimally-connected, easier-to-understand ‘mini systems’ / use cases. ...
Defining requirements.
Single process in a fictitious hotel using data flow diagram notation.
Single use case in a fictitious hotel using use case diagram notation.
This approach helps the analyst to decompose the system into ‘mentally bite-sized’ mini-systems using events that require a planned response. The level of detail of each response is at the level of ‘primary use cases’. Each planned response may be modelled using DFD notation or as a single use case using use case diagram notation.
The basic flow within a process or use case can usually be described in a relatively small number of steps, often fewer than twenty or thirty, possibly using something like ‘structured English’. Ideally, all of the steps would be visible all at once (often a page or less). The intention is to reduce one of the risks associated with short-term memory, namely, forgetting what is not immediately visible (‘out of sight, out of mind’). ...
Single process in a fictitious hotel using data flow diagram notation." [Event partitioning. Wikipedia]

Example of DFD for Online Store (Data Flow Diagram) DFD Example

Online Store Data Flow Diagram
Data Flow Diagram (DFD) is a methodology of graphical structural analysis and information systems design, which describes the sources external in respect to the system, recipients of data, logical functions, data flows and data stores that are accessed. DFDs allow to identify relationships between various system's components and are effectively used in business analysis and information systems analysis. They are useful for system’s high-level details modeling, to show how the input data are transformed to output results via the sequence of functional transformations. For description of DFD diagrams are uses two notations — Yourdon and Gane-Sarson, which differ in syntax. Online Store DFD example illustrates the Data Flow Diagram for online store, the interactions between Customers, Visitors, Sellers, depicts User databases and the flows of Website Information. ConceptDraw PRO enhanced with Data Flow Diagrams solution lets you to draw clear and simple example of DFD for Online Store using special libraries of predesigned DFD symbols.

"Cloud computing, also on-demand computing, is a kind of Internet-based computing that provides shared processing resources and data to computers and other devices on demand. It is a model for enabling ubiquitous, on-demand access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications and services), which can be rapidly provisioned and released with minimal management effort. Cloud computing and storage solutions provide users and enterprises with various capabilities to store and process their data in third-party data centers.
Cloud computing has become a highly demanded service or utility due to the advantages of high computing power, cheap cost of services, high performance, scalability, accessibility as well as availability." [Cloud computing. Wikipedia]
