Cloud Computing Architecture

"In computer networking, cloud computing is computing that involves a large number of computers connected through a communication network such as the Internet, similar to utility computing. ...
Network-based services, which appear to be provided by real server hardware, and are in fact served up by virtual hardware, simulated by software running on one or more real machines are often called cloud computing. Such virtual servers do not physically exist and can therefore be moved around and scaled up or down on the fly without affecting the end user, somewhat like a cloud becoming larger or smaller without being a physical object. ...
Typically, the seller has actual energy-consuming servers which host products and services from a remote location, so end-users don't have to; they can simply log on to the network without installing anything. The major models of cloud computing service are known as software as a service, platform as a service, and infrastructure as a service. These cloud services may be offered in a public, private or hybrid network. Google, Amazon,leadsquared.com, Oracle Cloud, Salesforce, Zoho, Access2MyPC, and Microsoft Azure are some well-known cloud vendors." [Cloud computing. Wikipedia]
The AWS architecture diagram example "2-Tier Auto-scalable Web Application Architecture in 1 AZ" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the AWS Architecture Diagrams solution from the Computer and Networks area of ConceptDraw Solution Park.

This example of cloud computing system architecture diagram was created on base of the figure "Workflow to distribute workitems to pooled VMs" in the article "Azure Batch technical overview" from the Microsoft Azure website.
"Workitems workflow.
Figure 4 shows a you how to submit an application to a pool where it's distributed for processing. This uses the Batch API. ...
1. Upload input files (such as source data or images) required for a job to an Azure storage account. These files must be in the storage account so that the Batch service can access them. The Batch service loads them onto a TVM when the task runs.
2. Upload the dependent binary files to the storage account. The binary files include the program that is run by the task and the dependent assemblies. These files must also be accessed from storage and are loaded onto the TVM.
3. Create a pool of TVMs, specifying the size of the TVMs in the pool, the OS they run, and other properties. When a task runs, it is assigned a TVM from this pool.
4. Create a workitem. A job will be automatically created when you create a workitem. A workitem enables you to manage a job of tasks.
5. Add tasks to the job. Each task uses the program that you uploaded to process information from a file you uploaded.
6. Run the application and monitor the results of the output." [azure.microsoft.com/ en-us/ documentation/ articles/ batch-technical-overview/ ]

"Users access cloud computing using networked client devices, such as desktop computers, laptops, tablets and smartphones and any Ethernet enabled device such as Home Automation Gadgets. Some of these devices — cloud clients — rely on cloud computing for all or a majority of their applications so as to be essentially useless without it. ... Many cloud applications do not require specific software on the client and instead use a web browser to interact with the cloud application. ... Some cloud applications, however, support specific client software dedicated to these applications (e.g., virtual desktop clients and most email clients). Some legacy applications (line of business applications that until now have been prevalent in thin client computing) are delivered via a screen-sharing technology." [Cloud computing. Wikipedia]
The infographic example "Cloud computing stack" was drawn using ConceptDraw PRO software extended with the Cloud Computing Diagrams solution from the Computer and Networks area of ConceptDraw Solution Park.

This cloud computing system architecture diagram example was created on the base of the picture in the post "Windows Azure Solution Cookbook" from the Clint Edmonson's blog notsotrivial.net.
"The diagram you see ... is designed to provide a layered architectural overview of the developer and infrastructure services currently available in Windows Azure." [notsotrivial.net/ blog/ post/ 2012/ 07/ 02/ Windows-Azure-Solution-Cookbook.aspx]
The diagram example "Microsoft Azure reference architecture" was created using ConceptDraw PRO diagramming and vector drawing software extended with the Azure Architecture solution from the Computer and Networks area of ConceptDraw Solution Park.

The vector stencils library "Azure architecture - Cloud" contains 227 Microsoft Azure architecture symbols.
Use this cloud computing icon set to design your Azure architecture diagrams with ConceptDraw PRO diagramming and vector drawing software.
"Cloud computing allows application software to be operated using internet-enabled devices. Clouds can be classified as public, private, and hybrid. ...
Cloud computing relies on sharing of resources to achieve coherence and economies of scale, similar to a utility (like the electricity grid) over a network. At the foundation of cloud computing is the broader concept of converged infrastructure and shared services.
Cloud computing, or in simpler shorthand just "the cloud", also focuses on maximizing the effectiveness of the shared resources. Cloud resources are usually not only shared by multiple users but are also dynamically reallocated per demand. This can work for allocating resources to users. ... This approach should maximize the use of computing power thus reducing environmental damage as well since less power, air conditioning, rack space, etc. are required for a variety of functions. With cloud computing, multiple users can access a single server to retrieve and update their data without purchasing licenses for different applications." [Cloud computing. Wikipedia]
