The ability to effectively use big data to gain value comes down to the ability of organizations to run analytical applications on the data, usually in the data lake. Assume that the challenges of capacity, speed, diversity, and accuracy are solved-measuring data readiness. The data is ready to pave the way for predictive analysis. Data readiness is built on the quality of the big data infrastructure used to support business and data science analysis applications. For example, any modern IT infrastructure must support data migration associated with technology upgrades, integrated systems, and applications, and can transform data into required formats and reliably integrate data into a data lake or enterprise data warehouse ability. 3 Challenges Faced by Big Data Transfer Technology Three big challenges facing big data technology, so why do so many big data infrastructures collapse early in the implementation life cycle? All this goes back to the last of McKinsey’s big data offer in 2011: “As long as the right policies and driving factors are formulated”. Some reasons why big data projects cannot be started are as follows: 1. Lack of skills Despite the increase in machine learning, artificial intelligence, and applications that can run without humans, the imagination to drive big data projects and queries is still a data scientist. These "promoters" referred to by McKinsey represent skills that are in great demand on the market and are therefore rare. Big data technology continues to affect the recruitment market. In many cases, big data developers, engineers, and data scientists are all on-the-job, learning processes. Many high-tech companies are paying more and more attention to creating and training more data-related positions to use the principles of big data. It is estimated that by 2020, 2.7 million people will be engaged in data-related jobs, and 700,000 of them will be dedicated to big data science and analysis positions to highly competitive and expensive employees. 2. Cost The value of the big data analytics industry is nearly $125 billion, and it is only expected to grow. For big data implementation projects, this means expensive costs, including installation fees and regular subscription fees. Even with the advancement of technology and the reduction of barriers to entry, the initial cost of big data may make the project impossible. Investment may require traditional consulting, outsourcing analysis, internal staffing, and storage and analysis software tools and applications. Various cost models are either too expensive, or provide the functionality of the minimum viable product, and cannot provide any actual results. But first, a company that wants to properly implement big data must prioritize architecture and infrastructure. 3. Data integration and data ingestion Before performing big data analysis, data integration must be performed first, which means that various data need to be sourced, moved, transferred, and provisioned into big data storage applications using technologies that ensure security. Control during the entire process. Modern integration technologies that connect systems, applications, and cloud technologies can help organizations produce reliable data gateways to overcome data movement problems. Companies striving to modernize their systems and deploy strategies to integrate data from various sources should tend to adopt a B2B-led integration strategy that ultimately drives the development of partner ecosystems, applications, data storage, and big data analysis platforms To provide better business value.

Data collection is not comprehensive, data storage is not standardized, data interaction is not timely, and the value of data is difficult to dig. Data problems are currently faced by small and medium-sized enterprises. In the Internet era, data is growing exponentially. If enterprises hope that data can be utilized to the greatest extent, for business value, or to guide the future development direction of the company, rapid data interaction, secure storage, and comprehensive collection are essential. For many small and medium-sized enterprises with an insufficient budget for informatization, it is the easiest way to deploy software that meets the needs of enterprise informatization construction. With the help of the mature process and simple operation of the transfer software, the process of data collection, cleaning, integration, and analysis is realized. The current high-speed large file transfer solution has powerful file transfer performance and financial-level security. The transfer speed is hundreds of times faster than FTP and HTTP. Run full bandwidth to improve file transfer efficiency; Based on SSL encrypted transfer protocol, financial-grade AES-256 encrypted transfer technology to ensure data security; Meticulous authority control mechanism, allowing appropriate permissions to be used by appropriate people; Support third-party cloud storage platforms, data storage safety is guaranteed. The use of these products is to take advantage of its cloud storage space and file transfer technical strength, and the enterprise itself does not need to build a computer room and set up specialized technical personnel to maintain it.

The value of any organization's technology integration depends to a large extent on the quality of its big data for digital transformation machines. In short: big data can achieve digital transformation, anyway, this is the goal. So how can big data technology bring success to enterprises in the grand plan of things? It turns out that it is not as good as hope. Optimistic expectations for big data may exceed our ability to actually execute big data. The latest research on the UK online consulting and consulting platform shows that 70% of big data projects in the UK have failed. The study goes on to say that almost half of all organizations in the UK are trying to carry out some kind of big data project or plan. However, nearly 80% of these companies cannot fully process data. However, this is not news. About three years ago, Gartner, a leading research and consulting company, reported similar situations on a global scale and predicted that 60% of big data projects in 2017 would fail the early implementation stage. Worse, this forecast is too conservative, because 85% of big data projects that year ended up flat. So why do so many initiatives fail to meet expectations? When trying to drive value through big data projects, what measures can be taken to increase the likelihood of measurable success? The promise of big data, despite the fact that so many organizations are still working on big data projects, there are some reasons. Volume and speed——Data explosion: exponential data from more sources from increasing speed of creation Diversity——Mobile and IoT terminals, the proliferation of traditional data types and the massive increase in the amount of unstructured data Accuracy——As the saying goes: "Garbage in, garbage out." Big data projects are only as good as providing data. Value——The white rabbit of big data. Discovering influential insights or new value streams for the organization is the biggest challenge. It is a symbol of differences in potential income and competition. Value is the reason for entering big data in the first place. The continued potential of analytics and the prospect of deliverables have turned big data into a multi-billion dollar technology industry in less than a decade. This has a lot to do with McKinsey Global Institute’s 2011 bold prediction of big data: “Big data will become the key basis for competition, providing support for a new round of productivity growth, innovation, and consumer surplus, as long as there are correct policies. And the driving force is in place." The idea is that almost every company in every industry is located in the large diverse, scattered, and disorganized enterprise data left in traditional systems and infrastructure. In the gold mine. Generated by a business. In order to obtain this treasure trove of information, each company needs specialized access and analysis tools to properly connect, organize, and ultimately transform it into a digestible and analyzable form. Assuming success, the big data infrastructure is expected to provide: Connect and unify all data sources Generate powerful business insights Allow predictive decisions Build a more efficient supply chain Provide a meaningful return on investment Comprehensively change every industry Although the potential of big data has been proven to be successful in many cases , the final state of big data required by most organizations has proven to be a difficult problem.

File synchronization is the process of ensuring that computer files in two or more locations are updated by certain rules. About file synchronization In one-way file synchronization , the updated files are copied from the "source" location to one or more "target" locations, but no files are copied back to the source location. In two-way file synchronization, updated files are copied in both directions, usually to keep the two locations the same. Nowadays, general file synchronization usually refers to two-way file synchronization. The general file synchronization system has the following functions: Encryption to ensure security, especially when compressing any data sent through the network when synchronizing via the Internet. Conflict detection modifies the location of the file on two sources instead of on one source. Undetected conflicts may result in overwriting the copy of the file with the latest version, resulting in data loss. For conflict detection, the synchronization software needs to keep a database of synchronized files. Distributed conflict detection can use the version vector to copy the data or application files in use or exclusively locked database files, "open file support" can ensure data integrity; Especially supports the use of intermediate storage devices to synchronize two computers. Most synchronization programs can be used in this way, but providing specific support for this can reduce the amount of data stored on the device;The ability to preview any changes before the change; The ability to view the differences in individual files; Backups between operating systems and Transmission between network computers; At present, more and more people have multiple intelligent terminal devices, which greatly facilitates people's work and life. The popularization of intelligent terminal equipment brings convenience to people but also brings new challenges to people's file management. How to ensure data consistency among multiple devices and how to efficiently synchronize files have become the focus of attention. When we want to process some work files when we get home, file synchronization can play a great role, and we can process work things at home just like in a company. Methods of file synchronization Tools used for file synchronization are, for example, Raysync, FreeFileSync, Syncthing, Dropbox, FileGee, GoodSync, etc. Let's look at a few of these methods! Raysync Enterprise-level Reliability Raysync can transfer large files on a full-bandwidth basis, which allows organizations to transfer files intact over any distance and network environment Mass-scale Synchronization It leverages the architecture to synchronize millions of small files or petabytes-sized files, and supports multiple concurrent sessions, clusters and 10 Gigabit transmission speed. Efficient Synchronization Efficient identification of file update status to avoid retransmission of the same file and reduce unnecessary synchronization Flexible Configuration Support Multiple Operations: one-way and two-way synchronization, timed synchronization, encrypted or unencrypted, keep modification time, transfer only source files, synchronized deletion, etc. Syncthing The biggest feature is the use of P2P distributed technology similar to Resilio Sync , which allows multiple devices to synchronize files with each other in real-time without a central server. The function is very close to Resilio Sync / BT Sync, but it says It seems to be a server software or cloud storage service application used to build network disks. Compared to server tools such as Seafile and NextCloud, Syncthing is actually more like a file/folder synchronization tool. Dropbox It is a free network file synchronization tool. It is an online storage service operated by Dropbox. It synchronizes files on the Internet through cloud computing. Users can store and share files and folders. Dropbox provides free and paid services. Dropbox's paid services include Dropbox Pro and Dropbox for Business. There is client software under different operating systems, and there are web clients. Realizing the safe synchronization of files can reduce the time spent on file backup and storage for freelancers and independent employees. The version backtracking function provides unparalleled convenience for some misoperations or version comparison. So that workers can focus more on work instead of documents. For enterprises, file synchronization is more convenient for managers to understand and control the progress of the entire project.

Transnational file transfer software is a problem that multinational companies need to face because it involves cross-regional transfer methods, then it will be interfered with by various factors, such as network speed, policy, security, etc. Below is our list of top 5 Transnational file transfer software. Cloud Network Disk This includes *Dropbox/GoogleDrive/Microsoft OneDrive/WeTransfer*. It is not difficult to see that these are some of the more commonly used network disks, but there will be some file size restrictions. Microsoft OneDrive Microsoft OneDrive supports 5GB storage space, if it is a single file, the maximum upload limit is 10GB, under normal circumstances, domestic users to transfer files overseas, the speed is normal. OneDrive has client software, supports file synchronization, and transmission supports breakpoint resumes. WeTransfer WeTransfer has no storage space limitation. The maximum limit of a single file is 2GB. The file will automatically expire after 7 days of storage. If it is accessed in China, the speed is slower, and the average is about 150KB. Currently only supports Web page upload, does not support file synchronization, does not support breakpoint resume, if the transmission is interrupted, you need to try again, limited to small file transmission better. Network disk system You need to build a network disk system yourself, which can support file synchronization. In the free version, it can support 3 clients. You need to apply for a server to install the software. There is no storage space limit, and there is no limit on the size of a single file transfer, but if you need to go from abroad If it is transmitted domestically, the transmission speed will be slower. Raysync Raysync is a professional open-source file transfer system independently developed by domestic companies. It can support large file transmission and file synchronization. The large file transfer software is better optimized for cross-border transmission. This data transfer method is suitable for enterprise users to transfer large files or cross-regional, cross-border transmission. Raysync transmission optimizes the existing network bandwidth and provides stable, secure transnational data transmission services. Other file transfer software exist in the market, but we can vouch for these 5. Ensure to take advantage of these data transmission services to improve your experience.

1. MQTT data encryption transfer algorithm An improved MQTT protocol data transfer encryption algorithm MQTT-EA is proposed. In this algorithm, the IoT device side and the server-side randomly generate their private keys, then notify each other of their private keys and combine them into the final session master key through the algorithm, which is encrypted and decrypted by DES to transmit secure data. The attack on the data transfer process by adversaries A and B is simulated, and it is verified that MQTT-EA is safe under the premise that the session key generation algorithm is not leaked. 2. Summary of key protocols and application scenarios of time-sensitive networks With the development of information technology, there is an increasing demand for scenarios where things and things are the main body of communication, such as factory automation control, automatic driving, etc. The requirements for data transfer delay of this type of communication far exceed the controllable range of traditional Ethernet. , The time-sensitive network came into being.

After testing, the system can accurately monitor agricultural environmental data in real-time, is stable and reliable, and can meet the needs of agricultural environmental monitoring.

Data movement is exactly what it sounds like: moving data from one place to another. We rely on various channels to communicate online, so we leave too much data behind, including data, files, etc. These become our important assets, so data to be moved is very important. In this article, we will analyze the definition of moving data, risks and challenges, and introduce some common data movement solutions. What's data movement? Data movement, is the ability to move data from one location to another within an organization using techniques, such as Extract, Transform, Load, Extract, Load, Transform , Data Replication, and Change Data Capture , Its purpose is mainly for data migration and data warehousing. The principle and importance of moving data In generally, the are two ways: replication and synchronization. Replication Provides a reliable and cost-effective way to create an accurate and up-to-date copy of your data from one or more sources that can be made available to anyone who needs access to it, no matter when or where they work. You can maintain control of the replicated database with flexible configurations for archiving and retention rules, data movement and breathing, and storage. Your data remains available for use in the original application or with analytics tools installed. Synchronization Keep replicated data up to date so users and applications have the best information available when working with it. You can update the replicated database in a batch or live configuration. For many relational databases, you can use the Change Data Capture feature to instantly synchronize new data. What are the risks and challenges of data movement? Because data is so valuable, it’s important to carefully plan and execute its migration. Issues during data movement can corrupt data, causing errors and inefficiency when it finally reaches its destination. Data Security Security is another common concern when dealing with data, especially for organizations that handle sensitive personal information like addresses, medical history, and the like. Make sure you take the necessary steps to ensure a secure data transfer. For an online movement, that could mean data encryption. Data Loss Risk During the data migration process, data loss can occur. When the data is migrated to the new system or target system, some of the data may not migrate over from the source system. Extended Downtime Risk The risk of extended downtime comes when the data migration process takes longer than expected. During the migration process, the source system is not active, so this poses potential risks for organizations and stakeholders. Capacity Issues Some businesses also run into trouble if they try to fit in data migration on top of their regular day-to-day work. Data migration can seem straightforward, but it’s still a very important undertaking that needs to be taken seriously.

Employees are a valuable asset of an enterprise and the cornerstone of its development. With the development of science and technology, there are more and more Internet offices, and employees can work through computers and mobile phones, which significantly improves office efficiency. At the same time, the disadvantages of Internet collaborative work are also highlighted in the process of the rapid development of enterprises. The flow of personnel is a common occurrence, but due to the popularity of Internet collaborative office, employees can obtain internal information anytime and anywhere, which poses an increasing threat to the internal information and core data of enterprises. In some resignation cases, we can see that some employees delete their own historical documents after resignation, which leads to business failure and delays work progress. In case of departing employees who steal the internal core secrets of the enterprise, take away the key technologies of the enterprise or resell information for competitors to obtain higher benefits, the enterprise will be hit hard and seriously affect the development of the enterprise. In order to protect the information security of enterprises, we have made a lot of efforts. Today, we analyze two aspects: people and information, hoping to help enterprises pay attention to the hidden dangers of information security brought by personnel mobility and protect the security of assets. Responsibility supervision Background investigation: Job seekers need background investigation, which can be carried out after both parties agree. The main purpose of the investigation is to screen out employees with bad reputation records or threats to enterprises and do preliminary prevention work. Signing Agreement: Enterprises can sign Confidentiality Agreement or Non-Competition Agreement when hiring employees, specify confidentiality content, responsible subject, confidentiality period, confidentiality obligation and liability for breach of contract, and strengthen employees' sense of responsibility. On-the-job training: Carry out "confidential knowledge training" for new employees entering the company, and create clear and comprehensive strategies to accurately outline which information, data, and documents are the property of the company, emphasize the importance of information security, clarify the consequences of data leakage, and strengthen employees' sense of confidentiality. Safe exit: Employees who leave the company are required to hand over all access rights to information and equipment to the company. In case of termination of work in HR's on-the-job employee platform, the IT department should quickly intervene and quickly cut off the equipment that may be used for authentication or allow the departing employee to connect. Similar security measures should be taken for the third-party organizations, partners, or suppliers that the company cooperates with, and quick measures are the basis for the company to avoid heavy losses. Data protection We can take responsibility for supervision for people and enterprises, and at the same time, we can also carry out protection measures for enterprises' own data and information. Permission setting: E-mail, data documents, and other forms of Internet leakage account for a large proportion of data leakage incidents. In this respect, enterprises can divide the data types, grades, and employee permissions, and manage the access, download, edit, copy, delete, and other fine settings in terms of permissions. Here, we can refer to the scientific design of identity authentication, user grouping, file outgoing monitoring, etc. File backup: In the era of big data, small groups, enterprises, companies, and large groups all produce a large amount of data in the process of development. Backup is the most direct protection for enterprises to deal with data loss and external attacks. In other words, there are traces of backup files. Security of office environment: the emergence of mobile office software is both convenient and risky for employees. For employees who carry office equipment or need to use office equipment outside the company to work, enterprises should strengthen the encryption protection of sensitive data and monitor the data flow.
