What is IBM Cloud Load Balancer
IBM Cloud Load Balancer is a managed load balancing service on IBM Cloud that distributes inbound traffic across multiple backend instances to improve availability and support horizontal scaling. It is used by teams running internet-facing or internal applications on IBM Cloud Virtual Servers and related IBM Cloud networking. The service provides configurable listeners, health checks, and routing policies through the IBM Cloud console and APIs, with options for public or private load balancers depending on network design.
Managed IBM Cloud integration
The service is operated and maintained by IBM Cloud, reducing the need to deploy and patch self-managed load balancer software. It integrates with IBM Cloud networking constructs (such as VPC and subnets) and is provisioned through the IBM Cloud console, CLI, and APIs. This fits teams that want load balancing as a platform service rather than managing their own proxies.
Public and private options
IBM Cloud Load Balancer supports both internet-facing and internal load balancing patterns, enabling separation of external and east-west traffic. This helps implement common architectures such as private service tiers behind a public edge. It also supports multi-backend distribution with health checks to remove unhealthy targets from rotation.
Standard L4/L7 capabilities
The product provides core load balancing functions such as listeners, backend pools, and health monitoring. These capabilities cover typical web and API workloads without requiring a separate reverse proxy deployment. For many IBM Cloud-hosted applications, this can be sufficient for baseline traffic distribution and failover.
IBM Cloud platform dependency
IBM Cloud Load Balancer is designed for workloads hosted on IBM Cloud and is not a portable component that can be deployed across multiple infrastructure providers. Organizations pursuing a single configuration across multiple clouds may need additional tooling or different products for consistency. This can increase operational variation across environments.
Less extensible than self-managed
Compared with self-managed load balancers and ingress controllers, a managed service typically exposes fewer low-level tuning knobs and extension points. Advanced traffic management features (custom plugins, bespoke routing logic, or deep proxy customization) may not be available or may require additional IBM Cloud services. Teams with specialized edge requirements may outgrow the built-in feature set.
Feature set varies by offering
IBM Cloud has multiple load balancing-related offerings across different IBM Cloud networking models, and capabilities can differ by region, generation, or deployment type. This can complicate standardization when migrating between environments or accounts. Buyers often need to validate exact protocol support, limits, and observability integrations for their specific IBM Cloud setup.
Plan & Pricing
Pricing model: Pay-as-you-go Free tier/trial: Product does not advertise a permanently free "Lite" tier. IBM Cloud provides a new-account credit (USD 200 for 30 days) that can be used for IBM Cloud services, including Load Balancers. Pricing metrics (official IBM documentation):
- Instance hours per month — measures number of hours the load balancer is used.
- Data processed (GB per month) — measures GB processed by the load balancer.
- Bandwidth usage (GB per month) — multiple pricing tiers apply. Notes: IBM's official product documentation (Load Balancer docs and catalog) describes the usage-based pricing model and points users to the cost estimator on the provisioning/catalog pages to calculate costs. However, the official public product pages and docs do not publish explicit unit rates (USD per instance-hour or USD per GB) that are directly visible without using the IBM Cloud cost estimator or the provisioning UI.
