As companies come to terms with big data, they have also come to accept that conventional data processing systems simply can’t keep up with its demanding requirements. Big data and AI have come a long way, and it has benefited companies and industries that rely on data to ensure smooth business operations. Without the proper tools, however, data processing and management can be extremely time-consuming and computationally demanding. The way data is used by different organizations depends on a number of contextual factors, since it can be used in a myriad of ways depending on the nature of the business. It also doesn’t end with collecting data, organizations need to find a way to abstract it to a form that can be processed by available data processing frameworks.
The main challenge with big data is the high velocity at which data is generated and its variety; this means that data should be processed quickly while considering the fact that it could include structured, unstructured, and semi-structured data. This is where Apache Hadoop and Apache Spark come in. Through parallel processing and distributed processing, they can help simplify data processing tasks when volume gets too high. Although both parallel processing and distributed processing involve breaking up computing processes into smaller parts, there is an essential difference between them: distributed processing is disk-based and parallel processing is not. Distributed processing “distributes” the workload by using several computers, while parallel processing accesses the same memory space but uses more than one processor.
One of the top big data frameworks still in use today, Hadoop’s reputation as the first ever big data framework ever released precedes the platform itself. It enjoys wide adoption because it has its own ecosystem of tools, the most popular of which, include Hive, Flume, Pig, and HDFS. Considered by many as the simplest of all available frameworks, Hadoop processes data logically. It’s highly fault-tolerant and isn’t dependent on hardware for availability. Designed to detect faults at the application layer, Hadoop replicates data across a computer cluster so it can build the missing parts in case a piece of hardware fails.
Hadoop uses the MapReduce algorithm to split data into blocks that can be assigned to different nodes within a cluster. MapReduce then processes the blocks in parallel so the pieces can be combined into the desired result. Although Hadoop started with MapReduce, it also has the capability to go beyond the algorithm through the use of certain tools, most notable of which, is YARN. YARN is considered the Hadoop ecosystem resource management layer responsible for job scheduling and management of computing resources.
Spark was created to address the “need for speed” of many organizations. Since Hadoop is disk-based, it performs noticeably slower than Spark, which uses in-memory processing. As such, Hadoop is ideal for batch processing and Spark, for iterative processing. Spark is also designed to address the limitations imposed by the linear data flow of the MapReduce algorithm. This allows for a more flexible pipeline and provides an ideal framework for Spark’s machine learning library, tightly integrated machine learning, MLib, and distributed modeling. Spark can also perform a variety of other big data workloads, including graph computations, interactive queries, and real-time stream processing.
Although some consider Spark as a Hadoop competitor, the two frameworks can actually work to complement each other and replace MapReduce completely. Using Spark in conjunction with Hadoop can free you from the limitations of the aging MapReduce paradigm, allowing you to leverage new technologies to enable faster data processing and filling in the gaps commonly found when working with Spark or Hadoop alone.
Which Big Data Framework is for You?
Hadoop and Spark are two open-source frameworks with key differences. Spark is designed to be fast, uses in-memory processing, and has libraries that can accommodate big data analytics. It doesn’t have a distributed file storage system, however, which Hadoop has. This file system is highly scalable, and needs only the addition of servers and machines to accommodate growing volumes of data and increasing workloads. In the era of big data, the key difference between Hadoop and Spark is in their design. Hadoop is designed for efficient batch processing and is, therefore, a high-latency framework without an interactive mode. On the other hand, Spark is designed to handle real-time data and minimize read/write cycles to disk, increasing overall data processing speeds. Spark is also easier to use than Hadoop because it doesn’t require coding and comes with user-friendly API’s that can be used in Scala, Spark SQL, Java, and Python. Despite Spark’s high data processing speeds, Hadoop still has the upper hand if the resulting dataset is larger than the available RAM. In such cases, the MapReduce algorithm will still outperform Spark.
While choosing the right enterprise database systems can be a challenge and will largely depend on the needs of the business, it’s a choice that has to be made so that the business can take a strategic approach toward data processing and management. Spark may be a newer and more modern solution, but Hadoop remains a relevant and major player when it comes to big data analytics. Ultimately, the decision will boil down to what your business needs are—and what you’re prepared to accept as a computing solution’s shortcomings.
Why SSD Disks Make Data Recovery Difficult
New storage units as an alternative to hard drives have become widespread in recent times: these are SSDs or solid state drives.
Unlike conventional hard drives, SSDs lack moving components, such as magnetic platters, read heads, or motors. Thus, the only element that SSDs usually have in common with conventional disks is the electronic controller and also, in most cases, a connection interface such as SATA.
SSD drives are based on flash memory technology. USB memories and SD cards, storage devices that are already part of our daily lives, also work with this technology.
How are SSDs better than conventional hard drives?
It can be said that the main advantage of SSDs over conventional hard drives is their response speed.
Standard hard drives need substantial time getting up and running. When starting, the motor should start to rotate to move the plates to the optimum speed; the reading heads must leave their parking area and move until they are positioned correctly. Then, for each operation, the heads must wait for the rotation of the plates and position themselves in the relevant area.
However, on an SSD disk, by working exclusively with flash memory, reading or writing data is much faster. The time it takes for the drive to wake up and be ready to go, almost instantly, is also much shorter.
Pros and cons of SSD drives
There is no doubt that SSDs have a much better performance, and that without a doubt, in the not too distant future, they will gradually replace conventional hard drives in large part of our computer equipment.
But not everything is advantageous with this type of device, with price and capacity being its main disadvantages. An SSD is more expensive than a standard disk of the same size. In addition, the maximum capacity that we can find today in the market for SSDs is much lower than that available in conventional disks.
One must keep in mind that SSD units are known to experience defects in their firmware or their controllers; These malfunctions can render the disk unusable and cause us to lose our data.
Most SSD models are programmed to permanently erase the free space that remains unused in the file system. Unfortunately, this has profound implications for accidental deletion of files or folders or when they disappear due to a logical error. So there’s a high risk that the disk will delete any remaining deleted or lost files, causing them to be irretrievably lost.
What to do in case of data loss
If you know that your computer uses an SSD disk and you encounter a situation of file loss or accidental deletion, we recommend that you immediately shut down your computer and put your SSD in the hands of professionals to carry out data recovery.
If the machine is still on –either by working with it, or by trying to recover the data at home–, for every moment that more data passes, it will be irretrievably erased by the device itself, making it difficult to recover the data.
This particularity of SSD disks can be considered a good security measure for those who want that no one can recover their deleted or old information, but it can also represent a great problem in case of loss of information by accident.
We end by remembering, as always, that the best prevention is to have one or more backup copies, updated and verified, so as not to find ourselves in need to request a data recovery.

Ways to Hire Services of IT Agencies
Many companies can bring marketing expertise in-house, which can be a significant advantage for keeping a hold on resourcing costs, maintaining control, and building a solid team for the great future. However, this approach also has some downfalls, mainly around the attraction of creative talent and the lack of independent, outside perspective that IT agencies bring to a creative brief.
There are many benefits to working with IT Support companies to partner on strategy, campaign planning, and skills building. Once you decide to hire the services of an IT agency, then the next steps in the process kick in. You can get digital marketing agency services to expand your business and boost it up.
Ways to Recruitment Services of IT Agencies:
In today’s fast world, no matter which business area your company operates in, it is virtually guaranteed that you will use technology at some point. It could be something straightforward, like primary electronic storage to keep all the data of your customer and the information of sales are well organized and easily accessible by all corporate team members.
It could be tons of intricate computer networks and devices, all of which are essential to keeping your company on the successful track. However, no matter how much technology you use, it will require the services of IT Support Companies at one point or another. There are lots of benefits of hiring a digital marketing agency. That’s the reason we will provide you with some ways to hire the services of IT agencies.
When you need to hire services of IT agencies, you must select the agencies who will give you the best rates of their services. Of course, you need quality work, but you can’t deny the fact that you don’t want to break the bank. Therefore it is vital when hiring services of IT agencies to select the one who provides you quality services in your budget.
Another thing that you must consider when hiring services of IT Support Companies is that ask about the working strategy of the IT agency for IT services. For example, do the IT Support Companies want to hire monthly retainers, or are they project-based? Since you are not paying for the benefits, your main focus is on whether you spend your money on the right IT agency.
Monthly retainers are more formalized and allow for better working conditions, as you can hire them only for large campaigns. Project-based work can cause disturbance because the IT agency will likely have to fit it around their stable retainer work. However, this will help you to check your relationships without long-term contracts.
Speed of Work:
It is also one of the essential points to consider when hiring services of IT Support Companies. Considering time is equally important as cost and quality. The reason is that you need efficiency, but you also don’t want the quality to suffer. Therefore, when you hire services of IT agencies, ask them, will they set you up on the monthly or yearly plan? How will the deliverables break down over a month or a year? How macho do you want to be? All these things are significant to ask from the IT agency before hiring their services.
Ask for Sample Work:
Before hiring the services of any IT agency, ask to show their prior work as a sample. For example, ask to see the web development work of previous clients they do, or you can also ask for the handles of accounts they have managed in the past. Not all IT agencies are created equally. Sample of previous campaigns or work the IT Agency has done will help you to decide quickly.
Before taking your decision to hire IT Support Companies for your business, it is imperative to consider all these above mention things.
Business Laptop Buying Guide
Currently, most equipped business laptops run 9549 or more. Most high-end laptops cost $ 750 or more, depending on how many bells and whistles you want to use with your product. Personalized laptops can improve your productivity.
When buying a business laptop, the first thing to keep in mind is that size does matter also to check buyerdirection. If you travel regularly or need something for the office, you should keep location in mind and buying a laptop will reflect that. Most business laptops are up to 12-17 inches in size, depending on the screen size, so you can pick up dirt when shopping for a business laptop.
Business systems require you to have a secure and fast hard drive. A hard drive under 7200 RPM is practically useless, so make sure you include something nice and big in your budget when shopping. Compare hard drives to other laptops and you might get some surprises.
Integrated graphics are required, but 3D graphics are optional, so you can choose in this area as well. If you are using a laptop for basic applications such as Word and Excel programs, built-in graphics will save you a lot of money. The more multimedia applications you have, the more graphics means more variety.
When shopping for a business laptop, along with size and graphics, security is very important. Check the options before buying and compare the product’s security benefits. One of the most interesting security features you can find in even the most affordable laptops is the fingerprint reader, which ensures that you can only access your laptop.
Size, security, graphics and hard drive space are the most important considerations when buying a business laptop. You can find a wide variety of units at different prices, so take your time and compare when shopping.
Finding the right laptop is frustrating as there are so many options, categories and unusual models to choose from. To help you get there, we have simple laptop buying guidelines to help you.
Who are you ?: Most laptop users fall into five main categories: students, business travelers, designers / photographers, game fans, and home users. If you are one of those people, it will make things easier because most laptops are classified according to their users. If you are not sure what to read.
Students: The average student’s budget is very small. He needs something portable, lightweight, and it can run for hours on a single charge. 11-inch network with 6-cell battery and 1GB of RAM is a great laptop for a student using Intel Atom. However, it does not have the processing power to run two or three applications at the same time, or to play games and watch HD movies.
Business travelers. Business travelers usually have a large budget, travel regularly for business, and transfer important information/files to a laptop. These users want very safe and durable laptops that can handle the offers and the hardships of travel. A laptop with a 12 ” to 15 ” display with Intel Wipro and TPM functions pays off. Most manufacturers such as Lenovo and Dell offer these laptops, while others offer shockproof, dustproof, and sealed laptops.
Designers / photographers. All photographers and designers work with multimedia. They need a little more processing power to store multimedia files, special graphics for image and video processing, and at least 500 GB of disk space. They also want large screens, and 15 to 17-inch laptops like the Apple MacBook Pro make them ideal for users.
