To help you understand its features and functionalities, we’ve compiled a list of frequently asked questions. Here, you will find answers to common inquiries that will guide you in leveraging this product to its fullest potential.
1. What is a Flexible Load Balancer on Kloudbean?
KloudBean’s Flexible Load Balancer (FLB) is designed to optimize traffic management and application performance across various cloud environments. It supports multiple cloud providers, enabling seamless traffic distribution across regions and providers, ensuring enhanced reliability and availability. Additionally, FLB allows for the configuration of multiple virtual load balancers on a single physical server, providing a cost-effective solution for agencies and developers. With its intuitive, one-click setup and simplified endpoint pool management, KloudBean’s FLB makes load balancing easy and accessible, even for users with minimal cloud infrastructure experience.
2. How does KloudBean’s Flexible Load Balancer work?
KloudBean’s Flexible Load Balancer is designed to efficiently route web traffic across multiple servers, ensuring optimal performance and minimal downtime. It uses advanced algorithms to intelligently distribute traffic, typically in a round-robin fashion, to the available servers where the application is running. If any endpoint becomes faulty or unresponsive, the load balancer automatically stops sending requests to that server, ensuring zero downtime and maintaining high availability for the application. This dynamic traffic management enhances reliability and ensures that users always receive fast, uninterrupted service.
3. What is a Virtual Load Balancer on Kloudbean?
A Virtual Load Balancer on KloudBean allows you to configure multiple load balancers on a single Flexible Load Balancer. This feature is particularly useful in microservices architectures, where different services require separate traffic management. By enabling multiple virtual load balancers on a single physical server, it becomes both cost-effective and efficient, eliminating the need for purchasing separate load balancers for each service. This setup simplifies management and reduces operational costs while maintaining optimal traffic distribution across your services.
4. How many Virtual Load Balancer can I create with single FLB?
The number of Virtual Load Balancers you can create with a single Flexible Load Balancer (FLB) depends on the size of the FLB you choose:
- Lightweight Load Balancer: Supports up to 4 virtual load balancers, designed for smaller applications or moderate traffic demands, handling up to 3,000 requests per second.
- Thunder Medium Load Balancer: Supports up to 8 virtual load balancers, offering a good balance for medium-sized applications or services with higher traffic demands, capable of handling up to 10,000 requests per second.
- Heavy Duty Load Balancer: Supports up to 12 virtual load balancers, ideal for high-performance applications or large-scale environments, capable of handling up to 25,000 requests per second.
These options provide flexibility based on your traffic needs, allowing you to scale and optimize your load balancing effectively.
5. Is the Flexible Load Balancer easy to configure?
Yes, KloudBean’s Flexible Load Balancer is super easy to configure. It’s a simple, few-step process that doesn’t require you to add or test any complex configurations. The user-friendly interface allows you to set up and manage your load balancing needs with minimal effort, making it accessible even to users with little to no experience in cloud infrastructure.
6. Can I use KloudBean’s Flexible Load Balancer with my existing infrastructure?
If your infrastructure, including servers and applications, is hosted on KloudBean, then you are good to use the Flexible Load Balancer (FLB). However, it is not possible to use the FLB with infrastructure that is not hosted or managed by KloudBean. The load balancer is specifically designed to work within KloudBean’s environment for optimal integration and performance.
7. Does KloudBean provide automatic scaling with the Flexible Load Balancer?
No, currently KloudBean does not provide an automatic scaling process with the Flexible Load Balancer. However, you do have the option to monitor traffic on your app and manually scale resources as needed. This can be done with just a few clicks on a demand-basis, allowing you to adjust capacity when traffic spikes or drops, ensuring your application runs smoothly without manual intervention for every change.
8. What happens if one of my servers fails?
If any of your servers or applications fail or stop responding, KloudBean’s Flexible Load Balancer (FLB) will ensure that no traffic is sent to the faulty endpoint until it is fixed. This proactive approach guarantees zero downtime for your users, as the FLB will automatically reroute traffic to healthy endpoints. Additionally, you can monitor your application’s health status through the Virtual Load Balancer Management section.
9. How can I exercise Blue Green deployment using Kloudbean FLB?
Yes, Blue-Green deployment is a fantastic feature offered by KloudBean’s Flexible Load Balancer (FLB). The process involves the following steps:
- Create an application replica: Set up a replica of your application to deploy new features or updates.
- Update code or features: Apply the recent code changes or new features to a few application nodes or the new application replicas.
- Add Blue applications to the virtual load balancer pool: Add the newly updated application replicas (Blue version) to the virtual load balancer’s application pool.
- Monitor performance: Once requests start flowing to these Blue application nodes, monitor them closely to check if there are any issues with the new features or updates.
- Rollback if necessary: If any breaking issues are observed, you can easily remove the problematic application replica from the virtual load balancer pool, effectively rolling back the deployment.
- Deploy if successful: If everything works fine, proceed with deploying the new features or updates to the other application nodes (Green version).
This process ensures zero downtime during deployment and allows you to safely test new features while minimizing the risk of introducing bugs into your production environment.
10. Can I use SSL certificates with KloudBean’s Flexible Load Balancer?
Yes, KloudBean offers both free and custom SSL certificates for your custom domain with the Flexible Load Balancer. For default endpoints, you do not need to provide your own certificates, as KloudBean provides a free SSL certificate for these endpoints. This ensures secure communication for both custom and default domains, simplifying SSL management for your applications.
11. What types of traffic can the Flexible Load Balancer handle?
The Flexible Load Balancer on KloudBean can handle HTTP and HTTPS traffic only. This makes it ideal for managing web applications and services that require secure and standard web protocols for communication.
12. How do I choose a region for the Flexible Load Balancer (FLB)?
When choosing a region for your Flexible Load Balancer (FLB), it’s best to select a region that is closest to your application servers and where you have the majority of your audience. This helps minimize latency and ensures faster response times for your users. By choosing a region that aligns with your infrastructure and target audience, you can optimize both performance and user experience.
13. How is billing handled for the Flexible Load Balancer?
Billing for the Flexible Load Balancer (FLB) is straightforward and transparent. There are no hidden fees or unexpected charges. FLB has a fixed cost, making it easy to understand and manage your expenses without worrying about fluctuating prices. This simple and clear billing structure ensures that you can easily plan your budget and costs for using the service.
