Why Monitoring Is Needed for Infrastructure

Infrastructure refers to the collection of virtual or physical resources which support the complete IT environment - storage, server and network. It provides the basic platform for transfer of data from one place to another. A suitable platform must be provided by the infrastructure, for all necessary IT applications as well as functions for an individual or the concerned organization.

Monitoring infrastructure becomes a need to mitigate risks, reduce costs and support the optimal performance of business. Monitoring systems are fast becoming a necessity to avoid any adverse situations that ensure that preventive measures could have been deployed before the crash of the network, leading to business loss in a direct manner.

Why is IT Infrastructure Monitoring Essential?

IT monitoring is crucial for the virtual, physical and cloud systems alike, to ensure the availability and for providing service which is efficient. It is highly recommended to conduct consistent monitoring of infrastructure, by most reputable IT consulting firms. This is emphasized so that it can be ensured that everything is working as it should.

7 Key Benefits of IT Infrastructure Monitoring

• Reliability - Infrastructure monitoring helps in keeping track of critical software as well as appliances. It helps in predetermining problems before these become problems which impact users. Due to this practice, a proactive approach towards dealing with issues is ensured. This is better, opposed to users contacting with a problem.

• Troubleshooting - With IT infrastructure monitoring, identification of problem causing devices becomes fast and easy and hence limits the downtime or the time wasted in the attempt to diagnose the problem.

• Planning for changes and upgrades - In case any device in the infrastructural system constantly runs near its limit, it may be an indicator for change. IT infrastructure monitoring helps in identifying such devices to plan upgrading required.

• Capacity - Thoroughly understanding how the devices are functioning and being used allows the proactive identification of the regions that require extra storage capacity.

• Trend Tracking - There are certain issues that arise intermittently or at specific peak time which can pose difficulty in being pin pointed immediately. On - going monitoring reports allow identify as well as understand these trends.

• Save Money - Noticeable reduction in the downtime and time spent for investigations, means lesser amount of money spent when any issue arises and greater productivity.

Increased profits - Avoiding the financial losses which may be caused due to undetected failure of systems is the ultimate result of proactive monitoring of infrastructure. When all services run as smoothly as they should, it definitely indicates an increase in profit statements.

The meaning and extent of infrastructure had witnessed expansion over time. More devices have connected to the basic infrastructure. Hence, as a matter of fact, regarding measurement and monitoring devices as well as other point specific items as being external to the IT infrastructure is better.

Why Fedora used by Red Hat Linux



Fedora is a Red Hat Linux code based OS that provides users latest free and open source software. It provides this software in a stable, easily manageable and secure form. It is one of the software created by the Fedora project funded by Red Hat Linux. Online Linux training invariably includes Fedora as a part of the curriculum. Why is it so?

Well Fedora focuses on innovation, integration of new technologies and works with many Linux developing communities. Being freely distributed with updates every six months it is the most evolving OS in the Linux community. Continuous upgrade means it is loaded with the newest technologies which makes it the best technology for experimentation. This is the reason it is a part of beginner Linux and rhce training as well. The cutting edge technology which is stable is the USP of Fedora and the reason behind it being part of Red hat Linux basics.

Is Fedora being used as a test platform for Red Hat Linux?


 Red Hat Linux community is promoting Fedora for development of new technology is indeed true. However it is not true that it is only Red Hat Linux that uses and contributes to the development of Fedora. There are many other contributors and just like some technology of Fedora is being used by the Red Hat Linux Enterprise, other distributors are also using it. Another thing is that Fedora though is upgraded every 6 months is a very stable and pre-tested software. So it is quite safe to use Fedora to learn new things. This is why it is being used by most online Linux training as a part of Linux introduction for beginners.

Red Hat Linux Enterprise and Fedora relationship


Red Hat Linux Enterprise and Fedora project have a relationship which is mutually beneficial for both. It ensures rapid innovation for Red Hat Linux and Fedora gets the sponsorship and feedback on issues with the new technologies. When the new tested technology migrates to Red Hat Linux it is available to a broader community which makes the technology robust for users. So Fedora is the incubator for latest technologies and innovation in Linux.
online linux training

In fact Red Hat Linux always tries to make Fedora rich with features which make handling computers much easier. Various features of Fedora like Network manager and Pulse Audio make it an enjoyable experience with the option of experimentation. After all Linux is open source which benefits from the feedback from its users and developers community. This is the reason for Fedora being part of Linux essentials and rhcsa training.

Ubuntu and Fedora


Now let us discuss the question of choice of Linux Operating system. Ubuntu is the most popular and user friendly while Fedora is loaded with the latest technology. So which one to choose? Well it depends on the use. If the user is just using the computer for office jobs which does not include programming then Ubuntu is of course the better deal. However with latest technology and regular development Fedora scores over Ubuntu in benchmarking tests. So it largely depends on the use of the software. If the question is to migrate from Windows Ubuntu is the obvious choice and if you are a serious programming nerd then Fedora is the best bet. Linux foundation recommends learning both Ubuntu and Fedora for a complete experience of Linux.

Why Linux command line is powerful tool



Before getting to understand why Linux command line is a powerful tool, let us try and know what a command line is. When you start off your online Linux training the command line invariably is the first thing you will see on the screen. It is a means to interact with the computer and ask it to do something.

Command Line Interface was the way to interact unless the development of Graphic User Interface system developed. Still it is the fastest and the most effective way to interact mainly used by computer professionals. Casual users now mostly use GUI (Graphic User Interface). However if you want to partake the Linux Administration Training command line knowledge is a must. This is what they start with at Red Hat Linux boot camp.

The main reason of the Linux command Line still remaining a powerful tool for developers, researchers and engineers is:
 Red hat training institutes
Quick and easy – If you are not using command line the commands may seem a bit difficult to remember, but it is the quickest way of operations. Graphic User Interface will take at least 100 times more time to execute the same task. For example take a simple task of rearranging the files, takes about 2 to 3 minutes to execute through a GUI. With a command line it hardly takes 30 seconds.

Can be customized – A window or a Mac has a GUI which runs in particular way and you cannot change it unless the change you want comes in the next update. Remember the boot time of Windows VISTA. However with Linux command line you can group commands together as per your need. You have to learn the commands, but to drive a car you need to learn too.

Great for programming – Command lines makes it easy to build programs at the kernel level which is impossible with GUI. That is the reason Linux command lines are among the most powerful tools.
Linux Fundamentals training 
Makes you learn how the computer works – While working with Windows or Mac GUI you would never have the idea how a computer works. While you learn the operation of Linux command in LinuxFundamentals training how the computer works and organizes. You will be surprised that the tasks you perform daily with the mouse are quicker when using a command line.

When you enroll for Linux Admin Certification Courses, make sure you have experimented with the Linux command line. You will learn quickly whether in a Linux coaching or Linux Course Online.
