Oracle Cloud Infrastructure Load Balancing

Oracle Cloud Infrastructure (OCI) Flexible Load Balancing enables customers to distribute web requests across a fleet of servers or automatically route traffic across fault domains, availability domains, or regions—yielding high availability and fault tolerance for any application or data source. The portfolio comprises two services—Oracle Cloud Infrastructure Flexible Load Balancer (OCI Load Balancer) and Oracle Cloud Infrastructure Flexible Network Load Balancer (OCI Network Load Balancer).

OCI Flexible Load Balancer primarily manages HTTP/HTTPS traffic and provides advanced routing features that distribute the requests based on the requests’ contents. In contrast, OCI Flexible Network Load Balancer performs at low latency, offering extreme performance.

Load Balancing features

Balance network traffic and workloads, either publicly or privately, to support scaling, high availability, and ensure application responsiveness.

Gain high availability

OCI Flexible Load Balancer offers a public IP address to front-end internet traffic within a single availability domain or across regions, ensuring applications are always available during peak demand.

Optimize traffic routing

Match your load balancing policy to your application requirements and optimize efficiency and reliability. Customers choose from round-robin, least connections, IP hash load balancing, or customized policies.

Multiple protocol flexibility

Customers use rules to define routing policies to balance incoming traffic with supported protocols such as TCP, HTTP, HTTP/2, and WebSockets. Automate load balancing tasks via API or web console.

TLS termination/SSL offloading

Transport Layer Security (TLS) termination decrypts SSL-encrypted data traffic (think of TLS as providing the ‘S’ in HTTPS). SSL termination also works to increase site and web application performance by reducing the workload scope of back-end servers. Customers can handle very high throughput SSL handshakes with the 8 Gbps load balancer shape.

Security built-in

Gain support for the modern TLS 1.2 protocol along with strong cipher suite for a secure front end to your application tier. Protect all traffic to your cloud with TLS encryption, and offload TLS handshakes to the load balancer. Leverage security lists to configure inbound and outbound access policies at the infrastructure level.

Low global pricing

Customer spend on load balancing is transparent and predictable, thanks to consistent global pricing, which offers savings of 100% or more in some geographies relative to competitors. For example, AWS ELB Network Load Balancer in Tokyo Japan is priced at 115% more ($0.0243 per Load Balancer-hour) than OCI Load Balancing ($0.0113 per Load Balancer-hour). OCI Flexible Network Load Balancer is offered at no cost to the customer.

Flexible performance

Create load balancers that will meet the performance you need and don’t be afraid of a surprise bill. OCI Flexible Load Balancer provides instant readiness for your workloads with minimum bandwidth and autoscales bandwidth based on the client traffic up to the defined maximum bandwidth. OCI Flexible Network Load Balancer scales up elastically based on incoming client traffic with no bandwidth configuration required.

Pass-through layer 4 (TCP/UDP) load balancing

Flexible Network Load Balancer preserves the original client packet (IP/Port) characteristics and load-balances them as is, without terminating the client session. The load-balancing decision is based on a hash of source/destination IP/Port and protocol information. It can provide network flow connection persistence based on client source IP and ensure that the subsequent requests from a client session are sent to the same back-end server.

Managed service provider gains competitive advantage and lowers costs by 30%

Data Intensity realized they could gain cost savings by migrating non-production and disaster recovery environments to Oracle Cloud Infrastructure. Their move resulted in 10X faster deployment and a 30% reduction in infrastructure costs. Data Intensity now runs customers' Oracle E-Business Suite workloads on Oracle Cloud Infrastructure Compute and Block Volumes, and they leverage Oracle’s highly scalable OCI File Storage for shared file systems during deployments to help optimize capacity consumption.
