VMware Architect: Introduction, Definition, Advantages, and Responsibilities

Introduction of VMware

VMware is a California-based company founded in 1998 that is developing a virtualization platform for IT infrastructure. VMware is known for its vSphere VMware hypervisor. The VMware hypervisor enables virtualization for all VMware architecture. VMware software developed by IT professionals in five different areas in 1998. VMware advances various types of virtualization application software and is today a leading provider of virtualization software.

VMware officially launched its first product, "VMware Workstation" around 1999. Later, they came with the server application "VMware GSX Server" in 2001 on the market. Since then, additional products have added to the stock. Their products are divided into two types.

·         System Applications
·         Server Application

System Applications: Some of VMware's desktop applications include Horizon Apps, Horizon 7, Horizon cloud, Horizon FLEX on Microsoft Azure, Horizon Infrastructure with Hosted Cloud, and more.

Server Applications: Some server-side application software is Rails, Microsoft .NET Framework, Microsoft IIS with .NET Framework on Windows Server, JBoss for Windows and Linux, vFabric tc Server, and so on.

What is VMware?

VMware: it is a cloud computing software and virtualization. The basis of VMware virtualization technologies is the ESX / ESXi hypervisor in the x86 architecture. A hypervisor is configured on the (physical) server so that several virtual machines can run on the same VMware server virtualization.

All VM can run their operating system. Several virtual machines on the same physical server share some of the shared resources, such as RAM, network, etc.

VMware software is now widely used in virtualized storage and networking, cloud management services, private data centers, office software, and more. VMware professional also started the VMWare ESX server and VMWare GSX server. The VMWare virtualization software is intended primarily for commercial use.

VMware vCenter Server architecture

The three major components of the vCenter Server architecture are:

·         vSphere Web Client.
·         vCenter Server database.
·         vCenter Single Sign-On.

VSphere Web Client: vSphere Web Client is a web application that acts as the user interface. The administrator can manage inventory objects and manage the installation on a vSphere prototype, and virtual machines can access the console. VMware software recently launched the vSphere Web Client based on HTML5 in its latest version (vSphere 6.5).

The vCenter Server database: Server data is stored and managed from resource groups and inventory items. Each instance of vCenter Server has its database.
vCenter Single Sign-On (SSO): SSO is a security token and authentication agent that the user can use to log in once to access the vSphere infrastructure. Further authentication is not required.

Advantages of VMware:

The activated administrator continuously monitors performance. VCenter Server affects the deployment of the virtual machine and blocks unauthorized access. Other benefits include simplifying integration with third-party products, reducing the impact of system errors, and automating workflows.

A server (vCenter) can handle multiple virtual machines alone. The number rises by connecting various occurrences. However, the capability of the server (vCenter) is vast, and this can also be a disadvantage. Therefore, the server database (vCenter) can store all the data. If the number of virtual machines in a given instance is overloaded, the risk of exceeding the database limits is higher: This results in the purchase of vCenter Server (in addition to the existing server).

VMware salary will not prioritize the Windows (vCenter) server during subsequent vSphere launches. The next version of the vCenter Server has replaced by the server application (vCSA) as a single prototype. Although the Linux version of vCSA has better scalability and configuration, vCSA can only run on virtual hardware and virtual machine clusters. The company can solve the problem by separately creating a group for vCSA. This process requires additional licenses and expensive equipment.

An overview of the different computer networks.

A Computer Network or simply a network refers to any number of independent computer systems that are interconnected to make data exchange feasible. For this, in addition to a physical connection, there must also be a logical connection between the networked systems — the latter produced by specific network protocols, such as the Transmission Control Protocol (TCP ). Even only two computers connected can be considered as a network.

The networks are set up, in particular, to transfer data from one system to another or to provide shared resources such as servers, databases or a printer on the network. Depending on the size and scope of the computer network, it is possible to differentiate and categorize systems. The following are the main categories of computer networks:

Different Types of Computer Networks

·         Personal Area Network (PAN) or personal network

·         Local Area Network (LAN) or Local Area Network

·         Metropolitan Area Network (MAN) or Metropolitan Network

·         Wide Area Network (WAN) or Wide Area Network

·         Global Area Network (GAN) or global network

The physical connection that connects these types of networks can be wired (wired) or made using wireless technology. In many cases, physical communication networks form the basis of several logical networks, called virtual private networks (VPNs ). These utilize a standard physical transmission means, for example, an optical fiber cable and, when transferring data, is assigned to logically different virtual networks using VPN software creating a tunnel (or tunneling software ).

Each type of network has developed for specific application areas — a network-based on own techniques and standards, providing different benefits and limitations.

Personal Area Network (PAN)

To enable data exchange of modern devices such as smartphones, tablets, laptops, or desktops, they can connect to a suitable network. It can join in the form of a personal network or PAN ( Personal Area Network ), it is also called home network. Standard transmission techniques are USB or FireWire. The Wireless Personal Area Network (WPAN)) relies on technologies like Bluetooth, USB wireless, INSTEON, IrDA, ZigBee or Z-Wave. A personal wireless network that can make via Bluetooth is called "Piconet." WPANs and PANs usually only cover a few meters and are not suitable for connecting devices in different rooms or buildings.

In addition to the communication of several devices with each other, a personal network also allows the connection to other systems, usually more significant. We are talking in this case of an Uplink or uplink. Due to the limited scope and relatively low rate of data transfer, NAPs are mainly used to connect peripherals for recreational use. Typical examples are wireless headphones, game consoles, and digital cameras. In the context of the Internet of Things (idO), IoT Internet of Things), WPANs used for communication, control, and monitoring of low data rate applications. Protocols like INSTEON, Z-Wave, and ZigBee designed for home automation.

Local Area Network (LAN)

If multiple computers are to join on a network, this is usually in the form of a Local Area Network (LAN ). Such a network can connect two computers in a house or several hundred devices within a company. But also networks in public institutions like administrations, schools, or universities are generally implemented in the form of a LAN. A widespread common standard for wired LANs is the Ethernet protocol. Other less common and sometimes obsolete technologies are Arcnet, FDDI, and Token Ring. The transmission of data is done electronically based on copper cables or via fiber optic cables.

If more than two computers are nested together in a local area network, additional components such as a hub, bridge, or switch (network switch) are needed and then act as bridging elements and distribution nodes. A LAN is designed to allow fast transfer of large amounts of data. Depending on the structure of the network and the transmission medium used, a data rate of 10 to 1000 Mbit / s is standard. Local networks allow a comfortable exchange of information between the different devices connected to the network. In the context of a business, it is common for many work computers to share file servers, network printers, or applications on the LAN.

Metropolitan Area Network (MAN)

A Metropolitan Area Network (MAN) is a broadband telecommunication network that connects several LANs. These are typically different branches of a company that connects to a MAN via leased lines. High-performance routers and high-performance optical fiber connections are used to provide a much higher data rate than the Internet. The speed of transmission between two remote nodes is comparable to the communication in a local network. As a metropolitan network, cable cities can integrate into extensive area networks: Wide Area Networks (WANs)) and internationally at the Global Area Networks (GAN ) level.

Wide Area Network (WAN)

While metropolitan networks connect areas that are close to each other in rural or urban regions, extensive area networks (WANs ) span massive geographical places across a country or region. A continent for example. In principle, the number of local area networks or computers connected to a vast area network is unlimited.

While local area networks (LANs) and MANs can make due to the geographical proximity of connected computers or networks based on Ethernet, WANs use techniques such as IP / MPLS (Multiprotocol Label Switching), PDH ( Plesiochronous Digital Hierarchy), SDH (Synchronous Digital Hierarchy), SONET (Synchronous Optical Network), ATM (Asynchronous Transfer Mode) and still rarely the obsolete X.25.

Extended networks owned by an organization or company and are therefore privately or rented. Also, ISPs use WANs to connect local area networks of companies and customers to the Internet.

Global Area Network (GAN)

A global network like the Internet is also called Globe Area Network (GAN ). The Internet is not the only computer network of its kind. Internationally active companies also maintain isolated networks that span multiple WANs and thereby connect corporate computers worldwide. GANs use the fiber optic infrastructures of wide-area networks and combine them with international submarine cables or satellite transmissions.

Virtual Private Network (VPN)

A  virtual private network (VPN) is a virtual communication network that uses the infrastructure of a physical interface to logically connected computer systems. It can be any network detailed above; however, the Internet is the most commonly used means of transmission. It connects almost all computers around the world and remains available for free as opposed to the private operation of a MAN or WAN. The data transferred within a virtual tunnel built between a VPN client and a VPN server.

What does a field engineer do?

Service technicians for heavy vehicles and mobile equipment, also called mechanics inspect, service and repair vehicles and machinery used in construction, agriculture, rail, and other industries.

Description of the field technician position

Service Engineer Job Description is to install equipment, repair errors, maintain and repair. These include electronic products, telecommunications equipment or devices. Retailers, cable companies and service companies employ field technicians who generally work full time during the first shift of the week. Field technicians travel to clients' homes and businesses to repair and install equipment and usually work independently and with little supervision. Finally, the field technicians inform the service manager.

Duties

The day-to-day tasks of field technicians vary depending on the team they work with and the number of service requests they receive during the day. However, these essential tasks are the same in most companies:

Install the equipment

Field technicians install devices and show customers how to operate them.

Troubleshooting and repairing devices

Field technicians solve equipment problems to determine the cause of the issues reported. Once the problem is detected, the device will be corrected to restore its full functionality. They also perform routine preventative maintenance.

Maintain newspapers

Field technicians write logs of each service call they make and add notes to customer records.

Advise Clients

Field technicians tell customers how to use the equipment and advise them on best practices for their equipment to work correctly.

Maintain stock

Field technicians manage inventory of their service vehicles and order new items when inventory levels are exhausted.

Maintenance of service vehicle

Retail service technicians keep their service vehicles clean and organized and refuel as required.

Service technicians repair and maintain a heavy and mobile plant, hydraulic systems, transmission and electrical systems for agricultural, industrial, construction and railway equipment. As the Field Technician Jobs are essential. They ensure the performance and safety of fuel lines, brakes and other systems.

Maintenance technicians use computers and diagnostic equipment to identify problems and to make necessary adjustments or repairs. For example, use an oscilloscope to look for signs produced by electronic components. Service technicians also use many power tools and various machine tools, including air wrenches, lathes, and welding equipment. A pneumatic tool is a pneumatic tool, as an impact key, powered by compressed air.

Service technicians also use many different hand tools such as screwdrivers, pliers, and wrenches to work in small and hard to reach places. Usually, they buy these tools during their careers and often invest thousands of dollars in their inventory.

After service technicians identify faulty equipment, they repair, replace and calibrate components such as hydraulic pumps and spark plugs. This may include the preparation and reconstruction of essential pieces of equipment or making adjustments employing an onboard computer program.

Farm machinery mechanics and service technicians repair and repair a farm service such as tractors and pickers. They also work with lawn and garden tractors with less consumer protection. Most businesses work for dealer repairs, where farmers provide their equipment for more and more maintenance.

Mechanics of heavy mobile equipment for the repair and maintenance of construction and open machineries, such as bulldozers, cranes, graders, and excavators. Most work for governments, loan and leasing companies, as well as large construction and mining companies.

Repairs to rail vehicles specialize in maintaining rail locomotives, subways, and other cars. They usually work for railway companies, public and private transport companies, and rail vehicle manufacturers.
