Complex and voluminous sets of different information represent Big Data.
But in their raw form, they do not make any sense, and to extract valuable information from them, they must go through the analytic process.
This helps identify trends, market preferences, and patterns of customer behaviors in the data, influencing more effective decisions concerning the business.
The complexity of big data urges new analytical tools such as machine learning, predictive and streaming analytics, and such techniques as database and cluster analysis.
In this article, we will analyze the benefits of big data analytics, how to hire a Cisco Spark developer, and what is the role of different engineers in big data analytics.
Useful Information About Big Data Analysis
Big data can be defined by four Vs:
- Volume for large amounts of data
- Velocity for frequency of incoming data
- Variety for many different forms of data, unstructured and structured
- Veracity for the credibility of the data
Among the advantages of solutions for the analysis of big data are the following:
1- Visibility
A robust big data analytics platform enables users to discover invisible trends and patterns in large and complex datasets that facilitate faster identification of strategic opportunities and threats.
2- A unified view of business
With a unified data architecture, companies are provided with a large, consistent, and comprehensive data window that improves decision making and enables users to work with the most accurate and timely information.
3- The fastest time for action
Big data analytics improves decision-making productivity by enabling anyone in the company to anticipate situations and opportunities, ask relevant and timely questions, and receive answers that lead to decisive action.

There Are Four Main Methods Of Big Data Analysis:
1- Descriptive analytics answers the question “What happened?” Analyzes real-time data and historical data. The main goal is to determine the reasons and patterns of success or failure in a particular area to use this data for the most effective models. Descriptive analytics use essential math functions. A typical example is case studies or web statistics data that a company receives through Google Analytics.
2- Predictive analytics helps predict the most likely course of events based on the available data. To do this, use ready-made templates based on any objects or phenomena with a similar set of characteristics. Using predictive (or predictive, predictive) analytics, you can, for example, calculate the collapse or change in prices in the stock market. Or evaluate the potential borrower’s ability to repay the loan.
3- Prescriptive analytics – the next level compared to predictive. With the help of Big Data and modern technologies, it is possible to identify problem points in business or any other activity and calculate in which scenario they can be avoided in the future.
4- Diagnostic analytics – uses data to analyze the reasons for what happened. This helps to identify anomalies and random connections between events and actions.

The more we know about a specific object or phenomenon, the more accurately we comprehend the essence and predict the future. By capturing and processing data streams from sensors, the Internet, and transactional operations, companies can reasonably expect the demand for products and emergency services can prevent man-made disasters. Here are some examples of how big data technologies are used:
- Healthcare. More knowledge about diseases, more treatment options, more information about medicines – all this allows us to fight infections that were considered incurable 40-50 years ago.
- Law enforcement agencies. Big data is used to predict crime spikes in different countries and to take deterrent measures where the situation calls for it.
- Public administration. Exploration and analysis of big data helps governments make decisions in areas such as health, employment, economic regulation, crime and security, emergency response;
- Industry. The implementation of Big Data tools helps to increase the transparency of industrial processes and introduce “predictive production”, which allows more accurately predicting the demand for products and, accordingly, planning the use of resources;
- Retail. The development of network and e-commerce is impossible to imagine without Big Data-based solutions – this is how stores personalize assortment and delivery.
- Internet of Things. Big Data and the Internet of Things are inextricably linked. Industrial and household appliances connected to the Internet of Things collect a vast amount of data, based on the analysis of which the operation of these devices is subsequently regulated;
- Real estate market. Developers use Big Data technologies to collect and analyze the entire array of information and then present the most exciting options to the user.

How to Find and Hire Such a Specialist
There are several options for hiring an engineer: in-house, dedicated team model, freelancer. We will look at all three options and analyze which one is most suitable for different businesses.
- Freelancer
A freelance engineer should be entrusted with tasks that are not core to the company. This is because such specialists work quite often remotely, which means they do not have the opportunity to fully integrate into the team, except that it also consists entirely of freelancers. We recommend resorting to the services of freelancers for all types of business. However, take into account the geographic remoteness of this specialist.

- Dedicated team model
The Dedicated Team Model is a financial engagement business model that is increasingly used in outsourcing and software testing. A dedicated team is a model of collaboration between customers and service providers. By signing an agreement to work on the “dedicated team” model, the client gets at his disposal specialists selected, taking into account the requirements for a specific product.
A dedicated team focuses entirely on the IT solution, while the client controls the workflow and can shift their focus to high-level tasks. The service provider is responsible for recruiting new talent and administering the team. Companies often choose DTM when they need to increase the size of the group within the company, but there is no time or opportunity to hire a Spark developer and train him.
- In-house engineer
Hiring a local development team means working with people who share the same culture and beliefs. This helps employees integrate effectively into the company, allowing them to add value to their work. The decision to hire a Cisco Spark developer as an in-house engineer is beneficial for large companies with a well-developed onboarding and corporate culture.
