General

Dedicated (static) IP address

Assigns every load balancer a dedicated static IP address that you can selectively share with other load balancers under a single account. IP addresses are persistent and won't change while a load balancer is active.

SSL termination

Offloads CPU-intensive public key encryption and decryption from application servers to the load balancer. Also provides HTTP to HTTPS redirect to help ensure transactions between the load balancer and client are secured.

Multiple protocols

Supports a variety of load balancing protocols on internal and public interfaces, including HTTP, HTTPS, LDAP, LDAPS, IMAP, FTP, POP3, POP3S, SMTP, TCP, TCP Client-First, UDP, SFTP and MySQL

Advanced access control

Enables you to easily manage who can and can't access the services that are exposed through the load balancer.

Connection logging

Simplifies log management by enabling Apache-style access logs (for HTTP-based protocol traffic) or connection and transfer logging (for all other traffic). Automatically sorts and aggregates log data, and sends the results to your Cloud Files account. This makes it convienent to access your raw data for performance tuning or web analytics.

Traffic Management

Advanced algorithmic routing

Cloud Load Balancers route traffic to backend nodes in the most optimal way for your application. Algorithm support includes round-robin, weighted round-robin, least connections, weighted least connections, and random.

Session persistence

Directs future requests to the same node in your load balancing pool. This can be enabled for all protocols.

Connection throttling

Imposes user-defined limits on the number of connections per IP address to mitigate malicious or abusive traffic to your application or website.

Primary/secondary node management

Prevents downtime by seamlessly routing traffic to the secondary node when there is a problem with the primary node.

Performance

High availability

Cloud Load Balancers have high-availability functionality built in. You only need to buy one load balancer to get high availability at no additional cost.

Health check

Uses synthetic transaction monitoring to inspect an HTTP response code and body content to determine if your workload is healthy.

Content caching

Improves website performance by temporarily storing recently accessed data.

High throughput

Each Cloud Load Balancer host machine has 20Gbps of highly available network throughput.

API

The Cloud Load Balancer API is a RESTful web service interface that lets you customize and automate load balancer management.

Simplified task management

Easily perform tasks like creating and removing load balancers, adding servers to a pool, or removing servers from a pool.

Token-based authentication

Allows seamless access between products and services.

Persistent connections

Reduces CPU/memory usage and network congestion by using a single connection to send and receive multiple requests.

Supports SSL termination

Increases the performance of high-volume SSL traffic by allowing SSL termination at the load balancer.

Gzip compression

Accelerates interactive performance of API calls and responses by encoding request and response body data.

Supports JSON and XML data serialization

Provides flexibility by supporting multiple data serialization types.

Regionalized load balancers

Improves performance speed by making it simple to localize your load balancer.
