2016

In Japan, 50 million "smart things" use Linter DBMS

In December, the Japanese company Brycen, a partner of the Voronezh company RELEX, told^[3]various options for the embedded version of the Linter DBMS already use over 50 million smart things of varying degrees of intelligence. RELEX representatives explained that there are two main options for the operation of their DBMS in class M2M or Industrial Internet of Things (IIoT) systems. In ^[4]

In the first of them, sensors located on relatively simple end devices (for example, video surveillance systems; devices for metering water, heat, gas or electricity) send their information to a node through wired or wireless protocols, where the DBMS reliably stores and quickly processes it and stores the processing results in the cloud.

If the "smart thing" (for example, a car, unmanned aerial vehicle or robot) is equipped not only with sensors, but also with actuators, then based on the data obtained as a result of the functioning of the Linter DBMS, these actuators can be controlled.

Of course, the built-in versions of the Linter DBMS do not work on their own, but under the control of any operating system (OS). The developers claim that their brainchild is currently compatible with more than two dozen different operating systems, including Rasbian OS (OS based on the Debian distribution) of the Raspberry Pi single-board microcomputer, which is often used in IoT projects. They say: "The advantages of LINTER are that this DBMS is not resource-intensive and allows you to practically not sacrifice functionality with very strict requirements for the amount of memory occupied."

Using the LINTER® M2M platform enables simple development of M2M systems without the need to develop communication control / operation management functionality in both the server side and device side applications. Installing the application DB on both the device side and server side improves the usability of the device, and improves the security of the data against situations such as power loss.

LINTER Bastion tested with EU2015-Terem

On February 18, 2016, I-Teco and RELEX announced the completion of the integration and testing of the LINTER Bastion database management system on the EC2015-Terem corporate virtualization software and hardware complex.

The purpose of testing is to create a platform for organizing corporate VDI/VPS systems based on the Russian technology stack. The companies began working in this direction in 2015. Specialists of partner companies conducted a set of compatibility tests of DBMS LINTER Bastion and PAC EC2015-Terem in the most popular operating environments: Linux (CentOS 7) and Windows (Windows Server 2008 R2 x86_64).

author = Vitaly Maksimov, Deputy General Director of RELEX Dependence on foreign computer manufacturers and software developers inevitably leads to vulnerability of information systems of Russian enterprises. Our task is to offer users secure platforms that will ensure normal operation without looking at foreign vendors. The experience of cooperation with I-Teco is another step towards the creation of domestic software and hardware solutions, the presence of which is extremely important today to ensure the safety and technological independence of Russian consumers.

To assess the effectiveness of the complex as part of DBMS LINTER and EC2015-Terem, at the final stage of work, comparative testing of a virtual platform with similar physical servers was carried out. As part of this stage, OLTP, OLAP and mixed DBMS load profiles were tested. The obtained experimental data was demonstrated - the EU2015-Terem virtual infrastructure provides performance comparable to systems on physical servers of the corresponding configuration, and in some cases exceeds their results.

author = Nikolay Parfyonov, Head of Ai-Teko CJSC As a result of successful tests, partner companies are ready to offer the IT market a high-performance PAC as a basis for building information systems using a domestic high-tech software product - DBMS LINTER. The goal of the project is to provide customers with the opportunity, relying on domestic developments, to build production and corporate IT systems, reducing dependence on foreign proprietary virtualization software, databases and hardware, reducing operating costs and building a strategic perspective for maintaining investments. Aiming at long-term mutually beneficial cooperation "I-Teco" and, RELEX we are already positioning the PAC "" - EC2015-Terem" DBMS LINTER Bastion" bundle as a component that ensures high reliability not only of the Russian, but also of the developing Eurasian software platform, complementing the joint product with new specifications and guarantees of compatibility with popular application systems. Recommending the enterprise virtualization platform "" and EC2015-Terem DBMS LINTER for joint use, we invite Russian enterprises to test this solution in application to their own production tasks.
