Companies are handling a large amount of data every moment. They also want insights into big data. This is not possible without dedicated ecosystems capable of handling such massive data. Many frameworks are available for big data processing, such as Hadoop, Hive, Apache Spark, MapReduce, and more. Learning at least one such framework is critical for a career in big data analytics, data engineering, or machine learning. So, how do you know which framework to learn?
As per benchmarks, Apache Spark is more popular because it is cost-effective to deploy. However, there are fewer Spark experts in the job market. Comparatively, MapReduce professionals are more readily available. So if you have decided to go for big data analytics training or a career in data engineering, opt for an Apache Spark Certification as the demand is high, and it will increase your chances of career growth.
What is Apache Spark
Apache Spark is an open-source framework for processing big data workloads. Its distributed processing system executes data engineering, data science, and machine learning tasks for fast queries and batch processing for advanced analytics on the Apache Hadoop platform. It processes in-memory and processes multiple workloads in parallel. The in-memory caching speeds up algorithms that call a function on a dataset. Reuse of data through DataFrames lowers the latency, making Spark a fast processing engine.
The platform supports easy-to-use native APIs in Python, Java, Scala, and R for a developer-friendly and flexible environment. As a framework for large-scale batch processing and stream processing, MapReduce can process large data sets at high speed while distributing tasks across multiple machines. All while enabling code reuse in batch processing, graph processing, real-time streaming analytics, and interactive queries for high performance.
Why take a Spark Certification
As a fast and general-purpose cluster computing system, Spark powers large-scale data processing and analytics tasks. Its immense capabilities are world players such as Netflix, Conviva, Alibaba, Yahoo, Apple, Google, and Facebook are adopting Spark. Spark has a wide range of applications across multiple industries.
Some instances are:
- Banking: Spark can detect fraudulent transactions, analyze customer spending for recommendations, and execute pattern identification for investments.
- Healthcare: From analyzing patient data to the identification of potential health issues and diagnosis based on medical history, Spark has found many uses.
- Entertainment: Entertainment companies like movie and video streaming engines use Spark for featuring relevant ads and recommendations based on user behavior. It also helps to offer a better user experience by eliminating screen buffering.
- E-Commerce: Large data sets can be analyzed for real-time transaction details, customer browsing history, cart abandonments, etc., for customized recommendations.
- Telecom: Telecom operators use Spark to process customer data for analyzing the optimal mix of products and minimize the tariff for the bundle of products in usage.
The wide deployment of Spark across industries and the many innovative use cases make for a strong case for an Apache Spark Certification. Certification offers you the perfect opportunity to learn a leading big data and analytics platform in high demand and boost your employability.
What is MapReduce
MapReduce is a Java-based framework within the Hadoop ecosystem. It is Hadoop’s native data processing engine. Its distributed component mitigates the complexity of distributed programming with two steps to the process: Map and Reduce. While Map splits the data across parallel processing jobs, Reduce handles the aggregate data from the Map step. MapReduce uses the Hadoop Distributed File System (HDFS) for input and output and supports the building of select technologies on top of it. As a software framework, it allows applications to be written for the processing of data on large clusters of commodity hardware running in parallel. This enables scalability with hundreds and more servers in a Hadoop cluster.
Differences and Similarities between MapReduce and Spark
MapReduce differs from Spark in that it processes data on disk, whereas Spark processes and retains data in memory for ensuing steps. Consequently, for smaller workloads, Spark’s processing speed is 100x faster than that of MapReduce.
MapReduce is used for writing data into the HDFS, whereas the Spark framework is used for faster data processing. While MapReduce cannot handle real-time processing, Spark can do it with ease. Apache Spark can cache the memory data for processing, which MapReduce cannot.
However, both frameworks also have some similarities. Both are open-source frameworks for scalable distributed computing. Spark’s compatibility with various data types and data sources is similar to MapReduce.
So let us explore how MapReduce and Spark compare:
MapReduce persists data back to the disk after a map or reduce action, but Apache Spark is faster as it processes data in RAM.
However, Spark requires a lot of memory as it loads a process into memory and caches it till called. So, while processing large data that does not fit in the memory, Spark may suffer major performance setbacks. But MapReduce stores data on multiple sources, processing it in batches for smoother performance. It kills the processes right after completing the task enabling it to run together with other services with minimal performance issues.
MapReduce excels in ETL-type jobs, and Spark supports iterative computations.
Spark is the better choice where all data fits into memory and dedicated clusters. MapReduce is the alternative for when data does not fit into memory.
MapReduce allows parallel processing of large data and outperforms Spark, where the resultant dataset is larger than available RAM. However, for iterative processing and graph processing or real-time processing, Spark out does MapReduce. Spark has a built-in machine learning library, while MapReduce needs a third party for machine learning tasks.
Spark is the choice for real-time processing and live unstructured data streams, while MapReduce works well for batch processing and linear data processing.
MapReduce scales up quickly to accommodate an increase in demand via the HDFS. Spark relies on fault-tolerant HDFS for processing large volumes of data.
For rapidly growing data volume, MapReduce is the choice for its high scalability as you can add up to n different nodes.
In terms of security, MapReduce ranks higher. It applies multiple authentication and access control methods making MapReduce more secure. Spark is less advanced when compared with MapReduce. In Spark, security is set to “off” by default and makes it vulnerable to attack. Authentication via a shared secret or event logging is the security consideration. Summing up:
MapReduce is the better option when security considerations are critical.
5. Failure Tolerance
MapReduce relies on hard drives rather than RAM. So if a process crashes during execution, it can resume the processing where it left off. Whereas, in Spark, the processing must restart from the very beginning.
MapReduce is somewhat better in fault tolerance than Spark.
MapReduce uses any disk storage type for data processing, but Spark uses high RAM to spin up nodes as it depends upon in-memory computations for real-time data processing.
For processing very large quantities of data, MapReduce is cheaper because hard disk space is less expensive than memory space.
7. Ease of Use
Although MapReduce is in Java, programming is difficult as code is required for each process. Also, it lacks an interactive mode. Spark has pre-built rich APIs for Java, Scala, and Python, and also has the Spark SQL for the SQL savvy. The simple building blocks make it easy to write user-defined functions.
Although Spark is easier to program, MapReduce has several tools that simplify programming.
Both frameworks are driven by the enterprise goals of faster, scalable, and more dependable data processing. Ultimately, the choice of the big data technology stack must consider the pros and cons of Spark and MapReduce.
Apache Spark is generally the tool of choice for data scientists and analysts. However, it depends upon the quantity of data processed by the framework. Processing big data requires careful consideration before choosing the best option. Both frameworks have features that the other does not have. So one must factor which framework best fits the data analytics needs before settling upon the framework and mastering it.

Artificial Intelligence in Business Analytics: Challenges for Investors and Developers
The current state of the market of AI for Business Analytics is showing upward trends and is supported by the leaders of most companies, who are ready to increase their investments in this area. A positive attitude towards the use of AI is associated with the benefits expected: optimization of business processes, increased efficiency, and capitalization of production, logistics, and distribution schemes, as well as consumer services. Is AI the prerogative of only large companies operating in international markets? What are the areas where AI technology is helping companies build effective business schemes? We will tell you in this article.
How global players are using AI tools
There are many tools for introducing AI into Business Analytics on the market. Examples are Data Robot and Alteryx, which provide Business Analysts with a friendly interface to improve employee productivity. These solutions allow specialists to save and catalog data in a form that is universal and convenient for processing by AI algorithms so that they make the necessary decisions in the future.
Among the leading players in the AI market for Business Analytics are Amazon, IBM, Nvidia, and Microsoft; as for popular products, we can mention such systems as Dataiku, Data Splunk, H20.ai, Modzy, SignalFx, and others. Microsoft, for example, offers a whole line of applications for its cloud platform Azure, which are defined as “mission-critical” by the vendor. With the help of AI, they perform such operations in data analytics as data management and verification, search and smart sorting, work with cloud storage, etc.
How other companies are putting AI into practice
When big players in the online retail market like Amazon, AliExpress, and eBay order data processing by AI models, it sounds cut and dried. Can companies that don’t belong to the high-tech industry or don’t view data as a key priority apply AI for data analytics and strategic planning? To answer this question, let’s look through a few examples.
The use of Machine Learning algorithms helps restaurant businesses regularly analyze electronic orders, predict the dynamics of demand, and improve the speed of service. For example, Domino’s Pizza has optimized a number of its processes by using the NVIDIA DGX-1 server, an integrated computer appliance system for Deep Learning, and a Machine Learning operational platform (MLOP) – Datatron. The latter helps to track and adjust the performance of the used models in real-time.
The introduction of these technologies has enabled the chain to make its branch and online operations better, improve client service, and distribute orders more efficiently. For example, a self-learning delivery forecasting model, trained on five million orders, can predict when an order will be completed. For this purpose, the model takes into account the parameters of the order and the service department – for example, the number of employees, managers, and clients who have made an order. Powerful servers have reduced model training time to one hour, increased order prediction accuracy from 75% to 95%, and made it possible to streamline data exchange between different departments.
Zachary Fragoso, Data Science and AI Manager at Domino’s, gave the following recommendation on the application of AI technologies for a business:
“Think about how your data scientists will work together and collaborate. In our case, the DGX-1 and our data scientists are interacting in a common workspace. It was something that our team didn’t really consider when we first acquired this product and has been a real value for us.”
Satellite map creation
An example of an outstanding application of AI tools for data analytics can be seen in the Blackshark.ai platform, which also uses NVIDIA DRIVE Sim technology to create satellite 3D maps of the planet.
Satellite imagery information is used by government agencies – for example, to assess energy consumption or tax revenues, including determining the size of buildings by the visible elements of ventilation systems. Also, analysis of data from seismic areas and places of frequent floods and tsunamis helps government agencies, private companies, and insurance organizations to better calculate risk structures and damage amounts.
Semantic reconstruction of analysis results helps businesses and individuals make critical decisions. Previously, images were usually processed manually to provide visual information with explanations, and now AI algorithms are doing this at high speed, providing the necessary semantic decoding.
The use of 3D models helps to make technological forecasts for cellular companies based on the analysis of the terrain and landscape elements. They model geospatial functions and analyze the range of coverage and engineering costs for optimal ROI when placing 3G, 4G, and 5G towers.
When healthcare provider organizations work with large amounts of medical data, analytics of this data is in high demand. As an example of how AI technologies are already helping to fight the coronavirus pandemic, we will cite the development of GlobalSNS under the AID-Tes brand. The project is designed for Israeli clinics that use PCR instruments for Covid tests.
Files from these instruments are imported into the system, analyzed by a shape detector, a bias detector, and a slope checker, and are normalized using the Savitzky-Golay filter. Then, the data is passed to the Ct controller and the threshold value calculator and, if possible, the system calculates its value by passing it to the result interpreter. The built-in validator checks the accuracy of the received data in comparison with the control samples, after which the interpreter gives its evaluation of the test result: positive, weak positive, negative, invalid, or requires a re-evaluation.
Mark Malko, a Business Analyst at Andersen and a solution team member, notes:
“The product is already used in clinics in Israel. It helps to interpret test results more accurately and rapidly (previously, it was done by the laboratory staff), which now requires fewer people. Since the work is carried out quickly, the clinic promptly informs patients about the test results, which reduces the likelihood of infecting other people.”
The influence of AI systems on the banking services’ performance indicators is convincingly demonstrated by McKinsey’s analytics.
AI tools for Business Analysis services and predictive modeling are widely used in a variety of areas, being in demand among both corporations and international enterprises and small companies. At the same time, although some developments have moved from the pilot stage of implementation to commercial use, a significant part of services and applications are at the promising startup stage. These new projects require investment from businesses that are seeking to optimize the performance of their processes.
What is Book Printing?
To make a book, there are two main methods: offset printing and print-on-demand book printing. Offset printing entails printing books in large batches in one go. Self-publishers typically choose print-on-demand. Both methods can be profitable for them. In addition, each method has its own advantages and disadvantages. Read on to discover more about book printing. Listed below are some pros and cons of offset and print-on-demand book printing.
The In-feed station for book printing is the final step of the process, and the process begins by loading a spool of paper onto a spool base. The size, type, weight, and width of the paper vary depending on the type of book you are printing. The spool base serves as a drive for the paper, which passes through a chain of rollers. The paper is guided through the chain without creasing or tearing, and the feed station is designed to keep the article straight.
Smart-binders are automated systems that automatically create batches of the pre-determined number of booklets. The Smart-binders can also be configured with an optional booklet stacker BSS-10 that can produce piles up to 330mm tall. The Smart-binder offers a number of benefits, including operator-free operation. Its software tracks each sheet through to a complete booklet, even if it’s not exactly the same size as the others in the run.
Reel stands for book printing are necessary tools for the book publishing process. The printing company uses this stand for all of their printing processes. This stands allows them to print on various types of paper. They are also used for catalogs and free-standing inserts. A reel is a convenient and affordable way to store the book. The reel is an essential part of the printing process, as it makes it easy for the customer to pick up the book and take it anywhere he or she wants.
With the advent of high-speed digital presses, book printing has undergone a major transformation. Traditional, continuous-feed toner-based presses have become obsolete, and the use of water-based inks introduced new challenges regarding drying and absorption. While book printing has traditionally been a slow process, new inkjet technologies have dramatically reduced the time required for production. Read on to learn more about the latest developments in book printing.
New continuous-inkjet web presses are available from a number of companies. HP, Kodak, and Domino offer monochrome configurations.. In addition to ink-jet press technology, these printers also have the same inline finishing equipment as their predecessors.
Endpapers are the strips of paper inserted between the text block and the board. They have many purposes, from serving as the first page of a book to serving as decorative elements. Endpapers have evolved significantly over the centuries and may serve many different purposes. Traditionally, they were blank, but today, they often are decorated, and serve as the binding’s last line of support. In addition to providing support for the joint, they can also be a decorative element in and of themselves.
When printing a hardcover book, endpapers are an important aspect of the process. Not only do they help preserve the valuable text inside, but they also take the burden off the first and last pages of a book. Endpapers are typically printed on thick, uncoated paper. Some endpapers may even be embellished with blind embossing or foil stamping to increase their visual appeal.
4 Situations Where You May Need The Help Of An Employment Lawyer
Most of us have heard of criminal lawyers, tax lawyers, corporate lawyers, and civil lawyers. But not many people are aware of employment lawyers. They are legal professionals who specialize in counseling clients with job-related issues. They provide a variety of services to employers as well as employees. There are reasons why one should hire employment lawyers, but here are a few to make you understand their work:
- They give professional advice regarding legal rights and obligations.
- The employment lawyer helps the employee file the complaint in case of harassment with the agency and explains the factors related to it.
- They fight for their clients when they are treated unfairly.
- They also defend employers against discrimination, wrongful termination, etc.
- They provide immediate help if the employee is exposed to an insecure work environment.
- Employment lawyers help clients understand their pay structure and benefits packages and determine whether their legal rights were violated.
Here are some issues that employment lawyers in Los Angeles can help you with:
- Sexual Harassment Issues
Every employee or employer is entitled to a healthy, supportive, and secure work environment. And sexually harassing anyone in your office is considered a violation of the employment law. Managers, employers, and other higher authorities are restricted from behaving in any unrespectful ways towards their workers. When asked for sexual favors or sexual advances, this is one of the situations when you might need the help of an employment attorney. Informed about the mistreatment, employment lawyers in Los Angeles have a legal obligation to take action and manage the situation.
- Retaliation in the workplace
Each employee is protected by laws that restrict employers from harassing employees who participate in any protest process. This might hurt the employee’s reputation or even the worker’s career or skill advancement. They also consider how an employee is regarded by the organization’s leadership. However, these processes aren’t limited to not following discriminatory orders, reporting harassment, giving evidence in any government case against the employer, saving another worker from sexual favors, etc.
- Signing an employment agreement
An employment agreement or employment contract is a legal document that oversees the relationship between an employee and an employer. It outlines your hours of work, the terms of your employment, compensation, and several employment policies. And if you’re asked to sign such contracts, it is important to have an employment attorney review your agreement to recognize areas of concern and negotiate possible changes to make the agreement more advantageous to you. Typically, there are dozens of items in an employment agreement that may cause problems for my employees.
- Wage and hour disagreement
Employers should pay their employees an appropriate wage according to their work, and they are not entitled to withhold the earnings of their employees. The dispute over wages and hours doesn’t only claim non-payment and underpayment of wages but also addresses inadequate break times, overtime issues, offenses of break time protections for nursing mothers, fair wages, tip compensation offenses, and the privilege of receiving salaries on time.
However, there are many more situations that might need the attention of an employment lawyer. We advise you to work honestly and never fail to raise concerns when needed.
Whether you break the law on purpose or unintentionally, an employment lawyer can guide you through the process of recouping your losses. And no matter how protected you are with your rights in a working environment, there might come a time when you are stuck in a dispute which might engage higher management. In conditions like these, you might need legal protection and you should know that talking to an employment lawyer is perhaps the best idea.
