FAQs
What is Virtuozzo Application Management?It is a Platform as a Service (PaaS) for building, deploying, and managing applications.
What does the platform do?It simplifies application deployment, scaling, and management through automation and containerization. It acts as an orchestration layer that is responsible for:
- Provisioning
- Templates configuration and clustering binding
- Environment’s lifecycle management
- Applications deployment
- Scalability management
- Handling requests via Shared Resolver
- Logs and statistics
- Billing
- Business analysis tools
- Monitoring and health checking
- and more.
What are the fundamental concepts of the Virtuozzo Application Management?Here are key components that make up the platform, organized from smallest to largest: cloudlets > containers > layers > environments > applications > hosts > regions > platform.
The following components are managed by the user:
- cloudlets: the main resource unit (128 MiB RAM + 400 MHz CPU)
- containers: isolated instances for specific services (capacity is primarily defined in cloudlets)
- layers: groups of the same type containers that work together
- environments: collections of services (layers and containers) that form a complete application
- applications: complex solutions that require multiple environments
The following components are managed by the service provider:
- hosts: physical servers that run containers
- regions: geographically distributed data centers hosting multiple physical servers
- platform: the overall infrastructure and services provided by Virtuozzo Application Management
What is a cloudlet?A
cloudlet is the smallest platform infrastructure resource unit that equals 128 MiB of RAM and 400 MHz of CPU power simultaneously. This high granularity ensures fair
usage-based pricing where you only pay for resources you actually consume.
What's the difference between reserved and dynamic cloudlets?Reserved Cloudlets are allocated in advance and charged whether you use them or not. They provide automatic discounts and are recommended for applications with steady, predictable loads.
Dynamic Cloudlets scale automatically with your application’s demand. They’re added when load increases and removed when it decreases, making them ideal for applications with variable or unpredictable resource needs.
For detailed information on how to configure both types, see the Cloudlet documentation.
