The article presents the structure of information technology to automate the development and deployment of a virtual cloud environment based on a serverless architecture. The process of creating information technology for automation of development and deployment of a virtual cloud environment based on serverless architecture is presented, the presented metamodel for prototype case study is evaluated and possible future directions of improvement are suggested. Although many software tools are available for deploying and managing complex cloud services, users often have to specify IaC solutions using low-level scenarios. Instead, known solutions require the developer to specify program components, such as a web application, and preferably the framework would automatically convert them to expandable code. To solve these problems and implement the desired capabilities, a modeled and scalable, fast-supply structure called Information Technology for Automating the Development and Deployment of a Virtual Cloud Environment Based on a Serverless Architecture (ІТаррх) is proposed. ITarrch meets the requirements of the topology specification for cloud applications, which allows you to create portable and interoperable templates for cloud services. The use of OpenTOSCA provides standardization of the delimitation of software applications and their dependencies on the specifications of the cloud platform.. The main contributions to this acticle are that the key elements of ІТаррх modeling are presented, which automates and masks the low-level details of application component specifications and cloud service provider specifications, and instead offers high-level intuitive representations; the use of an extended knowledge base and algorithms for automatic execution of IaC transformations is proposed; made a specific implementation of ІТаррх and its verification in the context of actual use cases.

The article discusses directions for improving the immunity of signals of control channels of unmanned aircraft complexes using complex signals. In order to implement the adaptation mode, it is proposed to use such devices for forming and processing signals of control channels that are rebuilt on command. This allows you to change: the parameters of a complex signal such as the base of a complex signal, the structure of the signal by pre-selecting it from the general ensemble, to perform a transition from one type of complex signal to another in accordance with the interference situation. These types of signal can be a discrete phase-manipulated signal, a discrete frequency-manipulated signal, i.e. with a pseudo-random frequency adjustment, or a combination thereof. It was determined that various types of complex signals have excellent capabilities in the fight against intentional jamming, which realize such properties as counteracting the suppression of the signal by jamming and concealment of its transmission to prevent parameter reconnaissance and eliminate the possibility of targeting jamming. To evaluate the effectiveness of complex signals, the selected indicator is the coefficient of suppression of interference by a complex signal based on the obtained analytical expressions for the values of the dispersion of the interference at the output of the correlation receiver after convolution of the complex signal. The second indicator of efficiency is the entropy hiddenness of a complex signal, which also varies for different types of signals. Such an indicator determines both energy and structural stealth, which significantly affects the time of exploration of the parameters of a complex signal. A conclusion was made about the expediency of using two parametric efficiency criteria, which comprehensively evaluates the main properties of a complex signal and allows to compare the types of signals for use in modems of the most effective control channels.
