How to choose hardware for Big Data processing

Computer processing of information has been used for decades, but the term "big data" – Big Data – had only become widespread by 2011. Big data has enabled companies to quickly extract business value from a wide variety of sources, including social networks, geolocation data transmitted by phones and other roaming devices, publicly available information from the Internet, and sensor readings embedded in cars, buildings and other objects.

What is VVV model?

Analysts use the 3V / VVV model to define the essence of big data. The designation is an acronym for the three key principles of Big Data: volume, velocity, and variety, respectively.

  • Volume means that Big Data analyses large amounts of information – from 10TB.
  • Velocity means that information for Big Data is generated and changed very quickly (just think of the speed at which new hashtags spread on Twitter).
  • Variety means that data in multiple formats comes from multiple sources (e.g. text and video messages from social networks, readings from geolocation services).

Where Big Data is used

Big Data is arrays of diverse information that is often generated, updated and provided by multiple sources. This is used by modern companies to work more efficiently, create new products, and ultimately become more competitive. Big Data accumulates every second – even as you're reading this, someone is collecting information about your preferences and browsing activities. Most companies use Big Data to improve customer service, while others use it to improve operational data and predict risk.

For example, VISA uses Big Data to reduce fraudulent transactions, World of Tanks game developers use it to reduce gamer churn, the German Ministry of Labour uses it to analyse unemployment benefit applications, and major retailers compile large-scale marketing campaigns to sell as many products as possible.

What does working with Big Data look like?

It can be divided into the following stages:

  • Data collection. This can be open-source or internal. The former include: data from government services, publicly available commercial information, social networks, and online services. The latter are analytics, online transaction data). Standard application interfaces and protocols are used for transmission of information.
  • Data integration. Dedicated systems convert it into a format suitable for storage, or monitor it continuously for important triggers.
  • Processing and analysis. Operations are performed in real time, except when information is stored as functions for later processing. Popular analysis techniques: associative rule learning, classification, cluster and regression analysis, data mixing and integration, machine learning, pattern recognition and others.

An important element of working with Big Data is search, which allows you to get the information you need in different ways. In the simple case, it works in the same way as Google does. Data is available to internal and external parties for a fee or for free – it all depends on the terms of ownership. Big Data is in demand from app and service developers, trading companies and telecommunications companies. For business users, information is offered in a visualised, easy-to-understand form. If the format is text, it will be concise lists and excerpts, if it is graphical – diagrams, charts and animations.

How to choose a platform for working with Big Data?

he handling of Big Data involves the use of a specific infrastructure focused on parallel processing and distributed storage of large volumes of data. But there is no one-size-fits-all solution for this purpose. Although a huge number of factors influence the choice of hardware, the only important factor is the software for Big Data collection and analysis. Accordingly, the process of purchasing hardware for a company will be as follows:

  • Choosing a Big Data software provider.
  • Researching the infrastructure requirements of the software developers.
  • Selection of hardware solutions based on these requirements.
  • Purchase of necessary hardware.

Thus, each project will be unique in its own way, and the equipment for its deployment will depend on the software chosen. Let's take for example two server solutions which are adapted to work with Big Data.

If you've been following Microsoft news, there's a good chance you've heard of Microsoft Azure, formerly known as Windows Azure. This cloud computing service is a big part of Microsoft's business, and it competes with similar services from Amazon and Google.

Microsoft Azure and the concept of cloud computing

Microsoft Azure is a cloud computing service that operates similarly to Amazon Web Services (AWS) and Google's cloud platform.

What is Microsoft Azure

By 'cloud computing' we do not mean the vague term often applied to consumer services that store your data on a remote server. We mean actual computing as a service for companies, organisations and even individuals who want to take advantage of it.

Traditionally, businesses and other organisations host their own infrastructure. A business would have its own web server (or mail server or whatever) on its own hardware. If more capacity was needed, the business would have to buy more server hardware. The business would also have to pay someone to administer this equipment and pay for a reliable Internet connection to serve its customers. In addition, there are hosting companies that host your services on some of their hardware in their data centres, for a fee.

Cloud computing works a little differently. Instead of running your own hardware or paying to use certain hardware in someone else's data centre, you simply pay for access to a huge pool of computing resources provided by Microsoft (or Amazon, or Google). This allows you to host web servers, email servers, databases, file storage servers, virtual machines, user directories or whatever else you may need. When you need more computing resources, you don't need to buy physical hardware. "The cloud shares the hardware and automatically assigns work as needed. You pay for as many computing resources as you need, not a specific number of hardware servers in a rack.

The services you deploy in this way can either be public servers available to all, or part of a 'private cloud' that is used only within the organisation.

What makes sense

When you use cloud computing, your initial costs are greatly reduced. You don't have to invest a lot of money in setting up your own data centre, buying hardware for it and paying for staff. There's no risk of overpaying for too much equipment, or buying too little and not having what you need.

Instead, you put everything you need to host it "in the cloud" provided by a service such as Microsoft Azure. You only pay for the computing resources you use. If you need more, it can scale instantly to meet demand. If you need less, you don't pay more than you need.

For this reason, everything from a company's internal email system to public websites and mobile app services are increasingly being hosted on cloud platforms.

What Microsoft Azure can do

The Microsoft Azure website provides a catalogue of hundreds of different services that you can use, including full virtual machines, databases, file storage, backups and services for mobile and web applications.

The service was originally called 'Windows Azure' but has been renamed 'Microsoft Azure' because it can do so much more than just Windows. For example, you can run Windows or Linux virtual machines in Azure – whichever you prefer.

Digging into those hundreds of services, you'll find you can do just about anything. And for anything Azure doesn't offer in a simple service, you can set up a Windows or Linux virtual machine that hosts whatever software you want to use. You can even host a Windows or Linux desktop in the cloud in a virtual machine and connect to it remotely. It's just another way to use remote computing resources.

A lot of what Azure does is not exclusive to Azure. Amazon, Microsoft and Google compete. Amazon Web Services, for example, is the leader in this area, ahead of Microsoft and Google's offerings.

Azure Active Directory and Windows 10

Microsoft also uses Azure to extend Windows in several important ways. Traditionally, organizations that wanted to have a central user directory and management of their PCs needed to run their own Microsoft Active Directory server. Now, in addition to traditional Active Directory software that can be installed on a Windows server, an organisation can use Azure Active Directory.

Azure AD is the same but hosted by Microsoft Azure. This allows organizations to have all of these functions centrally administered without requiring them to host their own Active Directory server (and configuring the often complex infrastructure and access permissions needed to run it remotely).

These services are not identical, but Microsoft is clearly betting that Azure AD is the future. Windows 10 users can join Azure Active Directory via Work Access, and Microsoft's Office 365 service uses Azure Active Directory to authenticate users.

Desktop or laptop? A desktop computer has many advantages: it's more powerful, it's cheaper, it's easier to upgrade and repair, it has a better keyboard, more ports, a bigger screen, and more. And only one drawback – the lack of mobility. So, what is the best laptop for hacking?

Panel Self-refresh is a technology by which the display displays a picture when there is no video signal, and changes it at the request of the GPU.

eDP also supports the integration of additional digital packages into the video signal, which allows other interfaces to be implemented on the display board. For example, you can add a microphone, webcam, touch surface, USB hub. This reduces the number of conductors in the cable to connect to the system board and reduces the cost of parts and maintenance.

Unlike LVDS, eDP reduces the total number of lines required for data transmission. And all without loss of quality and with clarity control!

In the next few years, I think the eDP standard will push outdated LVDS from the market. For clarity, I will give a table comparing the technical characteristics of interfaces.

Full HD matrices on the eDP interface are much cheaper than those with LVDS support. This also needs to be taken into account, but for me the choice was not so simple.

In the meantime, I settled on a 15.6-inch diagonal matrix.


Now you need to select the motherboard. It is she who will dictate her rules for supporting (or lack thereof) interface and other equally important connectors.

To choose a motherboard, you need to decide on its form factor. The mini-ITX, Mini-STX and thin mini-ITX formats are best suited to a fifteen-inch matrix.

Mini-ITX implies a motherboard with dimensions of 170 × 170 mm and support for desktop RAM. These boards have a 24-pin power connector from a standard ATX power supply, and the height of the interface connectors is about 4 cm.

Mini-STX is a fairly new motherboard form factor. Significantly smaller than mini-ITX at 147 x 140mm. The advantages include power supply from an external 19 V power supply. Disadvantage: the RAM slots are located vertically relative to the board, the connectors on the rear panel are made in two rows, which increases its size. Of course, they can be soldered, but this contradicts the original requirements for universality.

Thin mini-ITX – 170 x 170mm, same size as mini-ITX. But unlike it, the height here is one interface connector. In addition, such a board can be powered by an external 19 V power supply. My choice fell on the ASRock H110TM-ITX R2.0 motherboard.

HP Pavilion 15

HP Pavilion 15 is an ultraportable laptop that provides high performance, has a 15.6 inch full HD display, very useful for professionals who work in cybersecurity and hacking. The notebook supports many types of connections, including 1x USB 3.1 Type C Gen 1, 2x USB 3.1 Gen 1, 1x HDMI, etc. Pavilion 15 has an integrated webcam with a dual array camera, a digital microphone. Bydefault, the laptop comes with Microsoft Windows 10 Home 64-Bit operating system.

The weight is 4.08 pounds, so it’s quite easy to carry from place to another. This HP laptop has a built-in webcam with a dual array, a digital microphone. The laptop has a backlit keypad and numeric pad, helping you to type comfortably. The HP notebook comes with a solid state drive of 512 GB, which helps in penetration testing tasks. It also supports wireless communication standards like Bluetooth and Memory type like DDR4 SODIMM. The laptop has Intel Uhd Graphics with shared graphics memory, which helps in running a dual OS like Windows 10 and Kali Linux.

Lenovo IdeaPad

Lenovo IdeaPad is a good laptop to work on Kali Linux. It is one of the best options to have 14.0″ LED with an anti-glare display. This machine is AMD Ryzen 5 3500U processor that enables hackers to work seamlessly without any hassle.

When we talk about storage, such a laptop has SSD of 256GB and RAM of 8GB. It is sufficient for storing high-quality images and videos. Furthermore, you do not need an external hard drive. However, if you like to increase internal storage space, you can easily do it later on.

The design of this Lenovo IdeaPad is quite impressive compared to other laptops. Its weight is 3.3 pounds, and hence you can carry anywhere you want.

The battery life of Lenovo IdeaPad has 7 hours of battery life that enables you to work without interruption. You do not need a GPU for playing high-quality video as this laptop is equipped with AMD Radeon Vega 8 Graphics.

Podcasts are one of the simplest types of content. Unlike vlogging, you don't need expensive equipment. Let's talk about the best way to start by choosing the best laptops for podcasting.

Best laptops for podcasting 2022

How to record your first podcast: choosing equipment and software

Today, many people call podcasts the new radio. There is some truth in this: podcasts are attracting an ever-larger audience, they are listened to at home, in the car, on the subway on the way to work. The most important difference between a podcast and radio is that anyone can create their own, and for this you don’t even need special expensive equipment. We tell you how to choose the right equipment and software for recording podcasts, how much it can cost.

Computer or laptop: do not chase performance

Of course, you can also record a podcast from your smartphone, but this will give you a very entry-level product at the output. For better recording, a computer is indispensable. Unlike, for example, streaming, a podcast does not need powerful and productive equipment – it is enough to limit yourself to a simple and reliable laptop. The requirements for the characteristics are not high: for example, you can not pay much attention to the video card and be content with the integrated chip, it will not affect the recording of the podcast in any way.

The processor does not have to break performance records either, an Intel Celeron / Intel Pentium Silver chip (or a similar model from AMD) is enough to record a podcast. When choosing the amount of RAM, it is better to give preference to a laptop with 8 GB of memory (in extreme cases, at least 6 GB) – so the computer can easily cope with multitasking.

If you're planning on recording podcasts outside of your home, the portability of your laptop will also be important, so opt for a lighter model so you can comfortably move around the city with it. There are many models weighing around 1 kg – you will definitely have plenty to choose from. For example, Acer Swift 1 weighs only 1.3 kg and has a thickness of 1.5 cm – it will fit in almost any bag or backpack. Plus, the laptop has a well-implemented cooling system: it is quiet even under load, so no heart-rending howl of fans will be recorded.

Microphone: a simple buttonhole is enough

Almost everything depends on the sound quality in a podcast — you won’t be able to keep the audience even with the most interesting topic and the coolest guest if your conversation is accompanied by crackling, noises and echoes. The sound quality is directly affected by the microphone – let's talk about them in more detail.
For starters, there should be as many microphones as there are people in the conversation. If you're new to the world of podcasting, don't buy a port studio or mixing console right away: if your new hobby doesn't get you going, you'll be sorry for the money spent.

Start with a simpler solution – a USB microphone or a regular lavalier. Fundamentally, except for the form factor and connection method, they do not differ from each other: both start at about a thousand rubles for a decent entry-level model. Among lavalier microphones, for example, Boya BY-M1 can be distinguished – this is a budget and fairly high-quality device that will cost you about 1,500 rubles.
Pay attention to the interface: if you are going to write podcasts through a laptop, options with a regular 3.5 mm jack will do, if on a smartphone, it is better to look for a suitable USB or Lightning option.

However, microphones differ not only in connection method, but also in design: dynamic and condenser microphones can be distinguished here. For a beginner, it is definitely better to stop at the first option: such microphones have low sensitivity, therefore they “eat up” extraneous sounds, noises and echoes. Condenser microphones are extremely demanding on sound quality and room acoustics.

There is no universal advice on a microphone brand – you can look at the products of Audio-Technica, Behringer, Sennheiser, AKG.

Are you thinking of beginning your career as a podcaster for enjoyment? It is likewise suitable for spreading information. In order to start podcasting you will require a powerful computer and some other gear for that. So, nowadays I am reviewing some best laptops for podcast recording for you so you can choose one for yourself. You will need an ideal computer with great storage, a proper size display screen, and an effective processor for podcasting. But this is not all. Additionally, you should take into consideration some other factors as well such as battery life, memory space, and price. So, check them all out!
