Elasticity of Cloud Resources — A Response to Volatility in Demand for Public Services

In July 2019, the rapid growth in the number of active users of digital portals threatened the stability of traditional server architectures. Periods of active reporting, applicant registration, or mass requests for social assistance create peak loads that static departmental data centers often cannot handle. The challenge lies in transitioning from a model of owning limited “hardware” to a concept of dynamic resource consumption in cloud environments.

The IQusion team is a leading expert in developing cloud strategies for the public sector, where the key principle is the continuity of service provision regardless of external circumstances. We emphasize that infrastructure scalability must be automatic and imperceptible to the end-user. IQusion IT LLC focuses its efforts on creating hybrid models that combine the high level of security of local storage with the flexibility of cloud computing.

The Problem of Seasonal Loads and Limited Physical Infrastructure

The traditional approach to IT capacity planning involves purchasing equipment for the maximum possible load, which leads to expensive hardware sitting idle on normal days. In 2019, this model became inefficient due to the rapid digitalization of new registers, where predicting the number of requests is becoming increasingly difficult. IQusion sees a solution in implementing virtualization technologies that allow computing power to be redistributed among different tasks within a single pool.

IQusion IT LLC emphasizes the risks of system failures at moments of highest social significance for services, which undermines citizens’ trust in digital reforms. Physical servers have a limited performance threshold, and their expansion usually requires weeks for procurement and configuration, whereas the cloud allows obtaining the necessary resources in a matter of minutes. Such acceleration of reaction to market demands is a critical advantage for building a service-oriented state.

The implementation of cloud technologies also solves the problem of disaster recovery, as data can be replicated between several remote sites. IQusion specialists develop scenarios for automatic load switching in case of technical failures in the central node, guaranteeing 24/7 service availability. This creates a reliable foundation for integration with MobileID and other systems that require an instant response from authentication servers.

Hybrid Model as a Balance Between Security and Flexibility

For government agencies in 2019, the optimal path is to use hybrid clouds, where the most critical registry data remains within the protected perimeter of the agency, while front-office applications scale in the cloud. IQusion IT LLC offers architectural gateways that ensure secure data transit between these segments without the risk of confidential information leakage. This distribution allows handling millions of user interface requests without creating excessive pressure on the database core.

IQusion uses advanced microservice architecture methods that allow scaling not the entire system, but only those components that experience the heaviest load. For example, during the application submission period, the power of the file upload module can be increased, leaving other parts of the system in basic resource consumption mode. This provides unprecedented flexibility in managing state IT assets and significantly optimizes operational costs.

An important element of the hybrid strategy is ensuring full compatibility between different cloud platforms, which prevents vendor lock-in. IQusion IT LLC implements interoperability standards that allow instant migration of workloads between clouds in case of changes in tariff policy or security requirements. We build an architecture that remains under the full control of the state, regardless of the chosen infrastructure provider.

Elastic Matrix of Distributed Computing

To solve the problem of instant scaling, we propose implementing a specialized system for managing containerized applications, which acts as an intelligent resource orchestrator. This architectural model allows automatically creating new instances of services when a certain processor or memory load threshold is reached. IQusion sees this as a path to creating a self-regulating infrastructure that adapts to user behavior in real-time.

IQusion IT LLC integrates deep monitoring tools into this ecosystem, which allow predicting load spikes based on historical data and analysis of current traffic. Thanks to this, the system can begin capacity expansion several minutes before users experience a slowdown in portal operation. Such a level of automation is a basic condition for supporting integration with the “Trembita” bus, where the speed of message exchange between registers must remain stable under all conditions.

The use of an elastic resource model also increases the cyber resilience of the system, as a distributed architecture better withstands DDoS attacks and attempts of unauthorized interference. IQusion ensures the isolation of each container and implements automatic security rules that scale with the application. IQusion IT LLC creates an environment where the technological perfection of cloud computing works to strengthen national security in the digital space.

Cost Optimization and Cyber Resilience in a Cloud Environment

The transition to cloud capacities allows the state to abandon capital investments in hardware in favor of an operational payment model only for actually used resources. IQusion helps agencies develop transparent mechanisms for budgeting IT expenditures, where each spent hryvnia corresponds to the real volume of services provided to citizens. This significantly increases the economic efficiency of public administration and allows funds to be directed towards the development of new functionalities.

IQusion IT LLC pays special attention to the legal aspects of cloud usage, ensuring that solutions comply with information protection and personal data legislation. We implement multi-level encryption and access control systems that guarantee that even the cloud service provider does not have the technical ability to view data of national importance. Security in the cloud becomes not an obstacle, but an additional layer of protection thanks to professional platform administration.

The completion of the migration phase of key services to an elastic infrastructure in 2019 opens the way for global digital transformation. The IQusion team provides support for this process, training customer specialists in new methods of managing cloud assets. IQusion IT LLC remains a reliable partner in building digital sovereignty, where scaling technologies become a guarantor of the stability of state institutions.
