What is source IP hash?
What is source IP hash?
Source IP Hash load balancing uses an algorithm that takes the source and destination IP address of the client and server to generate a unique hash key. This key is used to allocate the client to a particular server.
What is source IP affinity?
Source IP Affinity (also known as session affinity or client IP affinity), an Azure load balancer distribution mode, ties connections from a single client to a single Azure-hosted server, rather than distributing each client connection dynamically to different Azure-hosted servers (the default load balancer behavior).
What is a 5 tuple hash?
A 5-tuple refers to a set of five different values that comprise a Transmission Control Protocol/Internet Protocol (TCP/IP) connection. It includes a source IP address/port number, destination IP address/port number and the protocol in use.
What is source IP persistence in load balancer?
When source IP persistence is configured, the load balancing virtual server uses the configured load balancing method to select a service for the initial request, and then uses the source IP address (client IP address) to identify subsequent requests from that client and send them to the same service.
What is Port hashing?
Port Hashing. The Port Hashing option, when enabled, determines which source and destination ports are to be taken into consideration. When the Hashing Dispatch Method is selected and the Port Hashing option is enabled, LinkProof selects a server for a session using a hash function.
What is session IP hash?
Session persistence With ip-hash, the client’s IP address is used as a hashing key to determine what server in a server group should be selected for the client’s requests. This method ensures that the requests from the same client will always be directed to the same server except when this server is unavailable.
What is 5 tuple load-balancing?
By default, Load Balancer uses a 5-tuple hash composed of source IP address, source port, destination IP address, destination port, and IP protocol number to map flows to available servers. You can choose to create affinity to a specific source IP address by opting into a 2- or 3-tuple hash for a given rule.
What is a floating IP?
A Floating IP is an IP address that can be instantly moved from one Droplet to another Droplet in the same datacenter. Part of a highly available infrastructure is being able to immediately point an IP address to a redundant server. This is now possible with the addition of Floating IPs.
What is load balancer?
A load balancer is a device that acts as a reverse proxy and distributes network or application traffic across a number of servers. Load balancers are used to increase capacity (concurrent users) and reliability of applications.
What is Private IP in Azure?
Azure assigns private IP addresses to resources from the address range of the virtual network subnet where the resource is. Azure reserves the first four addresses in each subnet address range. The addresses can’t be assigned to resources. For example, if the subnet’s address range is 10.0. 0.0/16, addresses 10.0.
What is the difference between source IP and cookie based persistence?
Source address persistence will persist on the incoming source address immediately on receiving a TCP connection. Cookie persistence, on the other hand, relies on return HTTP traffic – and will inject the cookie into the HTTP response sent back to the client.
What is a sticky session?
Session stickiness, a.k.a., session persistence, is a process in which a load balancer creates an affinity between a client and a specific network server for the duration of a session, (i.e., the time a specific IP spends on a website).
