Cloud Computing

Cloud computing is a very commonly used term in software engineering. It is known to be basically a software model as well as a computing infrastructure available for enabling the ubiquitous access to the shared pools of different configurable resources, such as servers, computer networks, storage, services and applications. Such computing infrastructure can be rapidly provisioned by managing it simply all over the Internet. The cloud computing allows enterprises and users with different computing capabilities to process as well as to store any needed to be stored and processed data in some privately owned cloud or on some other server, which are often located in the data centres for making such data accessing the mechanisms in a more reliable and efficient way. All the computing clouds rely upon the process of sharing the resources for achieving the economy of scale, being similar to such term as “utility”.

The cloud computing is also known to be allowing different companies to minimize, up-front and avoid the infrastructure costs, once it needs to be done. At the same time, all the so called “third-party clouds” are known to be enabling different organizations not to expend the resources on computer maintenance and infrastructure, but to focus on their main businesses. The proponents are known to be claiming about such cloud computing allowing the enterprises to get their applications running much faster, having less maintenance and more improved manageability at the same time, enabling the IT teams adjusting the resources more rapidly in order to meet the unpredictable and the fluctuating business demand.

Most of the cloud providers usually use a so called "pay as you go" model, leading to the unexpectedly high charges in case of the administrators being not as familiarized with the cloud pricing models. A cloud computing itself appeared after the high-capacity networks, the storage devices and low-cost computers, the widespread adoption of the hardware virtualization, autonomic and utility computing and service-oriented architecture became much more available, leading to their growth. In 2013 the cloud computing became a service in a demand, taking into consideration the advantages of its high computing power, high performance, cheap cost of services, scalability, availability and accessibility.

Some of the cloud vendors had their rates growing up to 50% per year, leading to the development of such service as “private cloud”, which is simply a cloud infrastructure, known to be operated only for one organization. Although such cloud is expected to be used by only one organization, it can always be managed not only internally, but also by a third-party, as well as being hosted both externally and internally. Using any private cloud project is known to be required by a significant engagement for virtualizing all the existing business environment, requiring the organization to re-evaluate its decisions about all the existing resources.

Such steps may lead to the improvements within business, raising the project security issues for preventing the serious vulnerabilities by every single taken step. The so called “self-run data centres” are known to be high capital intensive, having a significant physical footprint, but requiring the proper hardware, environmental control and allocations of space. The mentioned assets are known to be having to get periodically refreshed, which may result in the additional capital expenditures. Attracting the criticism from users who still have to buy, manage and build them, such assets are still very popular and in demand nowadays.

There are many kinds of the computing cloud. One of them is a so called "public" one, available when the services are rendered over some particular network, being open for a public use and being usually free. There may be a little difference between private and public cloud architecture, but the security consideration may be very different for services, such as storage, applications and other resources, which are made available for a public audience as well as for such cases when communication is being effected over some “non-trusted network”. Amazon Web Services (AWS) as well as Microsoft and Google are known to be the most popular public cloud service providers, owning and operating the infrastructure at their own data centres, having the access to them via the Internet. Microsoft and Amazon Web Services also offer the direct connect services called " Amazon Web Services Direct Connect" as well as "Azure ExpressRoute" requiring the customers to purchase or to lease a private connection to a peering point, which is offered by some of the cloud providers.

Working in IT dealing with the mentioned cloud computing services, you might have a need of creating the drawings of so called Cloud Computing Diagrams. To make any needed diagrams, including the cloud computing ones, it is always better to use the professional tool, such as a drawing software, for completing such diagrams in order to make them look simply smart and professional. One of the best applications nowadays is known to be a ConceptDraw DIAGRAM one, being one of the best tools for making such kinds of drawings: diagrams, charts, flowcharts, maps, schemes and many other different schematics.

Personal area (PAN) networks. Computer and Network Examples →

All computer networks differ by various params, and their size is one of them. As global area networks are the biggest, personal area (PAN) networks are the smallest. Personal computers, smartphones and other devices that have possibility to connect to Internet form a personal network. This diagram was created using ConceptDraw Computer Network Diagrams to represent a typical components of Personal area network. A personal area network (PAN) is the connection of IT devices around an individual person. This sample of personal area network involves a notebook, a personal digital assistant (PDA), and a portable printer. Commonly a PAN contains such wireless devices as mouse, keyboard, smartphone and tablet. A wireless connection is typical for a PAN.Personal area (PAN) networks

Local area network (LAN). Computer and Network Examples →

Computer networks nowadays are spread all across the world. The large number of parameters, such as geographic scale or communication protocols, can divide networks. One of the most common types of networks is called local area network (LAN). It convenient to represent network examples by means of diagrams. This local area network (LAN) diagram provides an easy way to see the way the devices in a local network are interacted. The diagram uses a library containing specific symbols to represent network equipment , media and the end-user devices such as computers (PC, mac, laptop) , network printer, hubs, server and finally a modem. There are two types of network topologies: physical and logical. The current diagram represents precisely a physical type of LAN topology because it refers to the physical layout of a local network equipment.Local area network (LAN) diagram

Flow chart Example. Warehouse Flowchart →

If you want to find a way to understand complex things in minutes, you should try to visualize data. One of the most useful tool for this is creating a flowchart, which is a diagram representing stages of some process in sequential order. There are so many possible uses of flowcharts and you can find tons of flow charts examples and predesigned templates on the Internet. Warehouse flowchart is often used for describing workflow and business process mapping. Using your imagination, you can simplify your job or daily routine with flowcharts. Warehouse flowcharts are used to document product and information flow between sources of supply and consumers. The flowchart provides the staged guidance on how to manage each aspect of warehousing and describes such aspects as receiving of supplies; control of quality; shipment and storage and corresponding document flow. Warehouse flowchart, being actual is a good source of information. It indicates the stepwise way to complete the warehouse and inventory management process flow. Also it can be very useful for an inventory and audit procedures.Warehouse Flowchart

Network Topologies →

When describing any computer network, we imagine a set of devices and nodes, arranged in some way. Talking about network structures, we should distinguish physical and logical network topologies, as physical topology is about devices location and logical topology illustrates data flow. In the same time, they do not have to match, and some devices, such as repeaters, may have a physical star layout, but a bus logical topology. There are two main types of computer network topologies: Physical topology that show the physical organization of a network - equipment and types of connections. Star network topology involves a set of devices that is connected to a single hub (router). Ring network topology means that, devices connected according this topology have two connections, connecting with nearby devices to make a loop. Bus network topology is the topology presented at the current diagram. It is similar to a ring topology. The difference is that data moves up and down a linear connection, copying itself where network equipment works as bus-stations along the way. This network topology can be used for small network, or when adding an extra device into a network.Network Topologies

Entity Relationship Diagram - ERD - Software for Design Crows Foot ER Diagrams →

There are many ways to describe a database structure. One of the most usual is to draw an entity relationship diagram (ERD) using a Crow’s Foot notation to represent database elements. If you don’t want to draw it on paper, you should use an appropriate software. An entity-relationship (ER) diagram is used to show the structure of a business database. ERD represents data as objects (entities) that are connected with standard relationships symbols which Illustrate an association between entities. ERD, there is a wide range of ERD notations used by data bases architects for reflecting the relationships between the data entities. According to the crow’s foot notation relationships are drawn as single labeled lines designating a certain kinds of relationship. Crow foot notation is a most frequently used ERD standard, because of improved readability of diagrams, with a more accurate use of space on the page.Entity Relationship Diagram - ERD - Software for Design  <br>Crows Foot ER Diagrams *
