Quasar AEP on AWS

Challenges

Telecom providers face mounting challenges due to rapid technological changes and the increasing need to integrate with new business domains and models. Maintaining legacy services, such as SMS and voicemail, creates operational complexity and strains resources, even though these services no longer drive significant revenue. Integrating these outdated systems with modern technologies is difficult, often leading to a disjointed network structure. Legacy systems also limit flexibility, making it hard to implement changes in business logic or adapt to evolving customer expectations. Additionally, balancing a consistent customer experience across both legacy and new services remains a persistent challenge for Mobile Network Operators (MNOs).

Our Solution

Quasar Application Engine Platform (AEP) a modular, model-based, and event-driven platform specifically crafted for the creation, deployment, and operation of real-time applications within carrier-grade environments. Deployment of Quasar can be done in 2 modes a) on - prem and b) on Cloud - AWS platform. Providing a central interface that integrates drag-and-drop functionality, AI support, and the flexibility to “bring your own code” plus robust automation capabilities, it empowers users to manage the complete service lifecycle of critical applications – design, build, operate – with ease. The features provided by our platform (visual service design, automated test generation, concurrent service versions, multi-tenant, advanced session tracing, overload protection) allows MNOs to migrate safely the legacy services and develop new services iteratively, exploring possibilities and adjusting to emerging standards or business models.

• Model based - Same visual model shared during design and runtime
• Domain Specific - Use a customizable domain specific language via drag-n-drop
• Event Driven - Simplified state-charts as model during design and executed during runtime
• Platform - Dealing with synchronization, timers, scalability, overload, high availability, etc
• Deployment - AWS Cloud

Key Features

Augmented Development

• Low code features merged with AI/LLM assistance enable building a visual unified model for each service; this model is directly executed without any further translations, exactly as it is, by runtime.
• Domain experts can easily reason about the application based on the visual model and they can make changes without involving software development teams
• The model is used to execute the application, to generate Web UIs when needed, and to build tests automatically

Efficient Operations

• Deploy applications from your CI/CD pipeline via exposed management APIs or from web UI at one click button
• Day time upgrades, no downtime for your service; promote versions to production or revert changes instantly
• Build and execute test cases, capture and compare results; simulate any external integration out-of-the-box
• Use call-by-call detailed tracing with possibility to export entire call trace and replay it in a different environment
• Out-of-the-box high availability, fault recovery, overload protection with degraded mode, session replication

Full Flexibility

• Bring your own code to the platform; simple interfaces to deploy third party functions and components

Unmatched Performance

• Low latency (<12ms for 99% of calls) with horizontal scalability
• Less than 9000 TPS for calls and messages
