Load balancing features improve performance

Cloud Load Balancers include an array of technologies that help ensure your websites and applications are online and highly responsive, while guaranteeing 99.99% uptime.

Dedicated (static) IP Address

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

SSL termination

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

High Availability

Built in high availability

Our Cloud Load Balancer solution has high-availability functionality built in. You only need to buy one load balancer to get high availability at no additional cost.

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.

High throughput

Each Cloud Load Balancer host machine has 20Gb per second of highly available network throughput.

Advanced algorithms

Ensures traffic is properly routed to back-end nodes in the most optimal way for your application. Algorithm support includes round-robin, weighted round-robin, least connections, weighted least connections, and random.

Health check

Uses Synthetic transaction monitoring to inspect an HTTP response code and body content to determine if the application or website is healthy.

Advanced access control

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

Session persistence

Ensures subsequent requests are directed to the same node in your load balancing pool. This can be enabled for all protocols.

Connection logging

Simplifies log management by allowing Apache-style access logs (for HTTP-based protocol traffic) or connection and transfer logging (for all other traffic) to your Cloud Files™ account. If you need raw data in one place for performance tuning or web analytics, connection logging sorts, aggregates, and delivers logs to Cloud Files.

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.

Content caching

Improves website performance by temporarily storing recently accessed data.

Primary/secondary node management via API

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

Programmatic access via API

The Cloud Load Balancer API is implemented using a RESTful web service interface. You can use this full-featured API to perform tasks like creating and removing load balancers, adding servers to a pool, or removing servers from a pool.

  • REST-based API: Lets you customize solutions to automate Cloud Load Balancer management.
  • Token-based authentication: Allows seamless access between products and services.
  • Persistent connections: Reduces CPU and 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.

Riverbed® technology

Utilizing Riverbed's load balancing technology, our Cloud Load Balancers service directs traffic for your applications and makes decisions about where to route that traffic. In the event of a node failure, a health check can proactively remove a node from rotation to ensure maximum availability. You can adjust the configuration of the load balancer on-demand through the control panel or programmatically through the API.
