How are load balancers configured?
You must provide a basic configuration for your load balancer, such as a name, a network, and a listener. It is configured with a protocol and a port for front-end (client to load balancer) connections and a protocol and a port for back-end (load balancer to instance) connections.
How do you manage load balancing?
Load Balancing Algorithms
- Round Robin – Requests are distributed across the group of servers sequentially.
- Least Connections – A new request is sent to the server with the fewest current connections to clients.
- Least Time – Sends requests to the server selected by a formula that combines the.
What is OCI load balancer?
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.
What is Alb and NLB?
Application Load Balancer (ALB) should be used to balance Layer 7 traffic across multiple services. Operating at Layer 7 it offers the most flexible routing based on a number of options like path-based routing. Network Load Balancer (NLB) should be used to balance Layer 4 traffic across multiple services.
What is load balancer how it works?
A load balancer acts as a ‘reverse-proxy’ to represent the application servers to the client through a virtual IP address (VIP). The load balancer works to steer the traffic to a pool of available servers through various load balancing algorithms. If more resources are needed, additional servers can be added.
Which protocols does OCI load balancers support?
The load balancing service supports TLS 1.0, TLS 1.1 and TLS 1.2 protocols. You can choose from one of the Oracle-provided cipher suites or create your own custom cipher suite with specific ciphers.
Which three protocols are supported by the OCI network load balancer?
Network Load Balancer service supports three primary network load balancer policy types:
- 5-Tuple Hash: Routs incoming traffic based on 5-Tuple (source IP and port, destination IP and port, protocol) Hash.
- 3-Tuple Hash: Routs incoming traffic based on 3-Tuple (source IP, destination IP, protocol) Hash.
