What is Gslb and how does it work?

Global server load balancing (GSLB) is the act of load balancing across globally distributed servers. This allows distribution of traffic to be performed efficiently across application servers that are dispersed geographically.

How does Gslb Citrix work?

GSLB receives a DNS query, and then GSLB sends back an IP address, which is exactly how a DNS server works. The user then connects to the returned IP, which doesn’t even need to be on a NetScaler ADC. GSLB is only useful if you have a single DNS name that could resolve to two or more IP addresses.

What is the purpose of Gslb?

Global server load balancing (GSLB) refers to the intelligent distribution of traffic across server resources located in multiple geographies. The servers can be on premises in a company’s own data centers, or hosted in a private cloud or the public cloud.

How does DNS work with Gslb?

The GSLB DNS server gives the IP address to direct the user to the datacenter according to GSLB distribution algorithm selected. The user connects to the IP address communicated by the GSLB’s DNS service. The application server is answering directly to the user.

How do you implement Gslb?

To access the wizard, navigate to Configuration > Traffic Management > GSLB and then click Get Started. You can also access this wizard from the GSLB dashboard. Navigate to Configuration > Traffic Management > GSLB > Dashboard and then click Configure GSLB.

How does Gslb work with DNS?

What is Gslb in AWS?

Global Server Load Balancing (GSLB) is typically used to provide data center failover or to enhance end user performance by directing users to their closest data centers using geolocation. GSLB is a DNS based system that manipulates the DNS response based on the availability and performance profile of the data centers.

What are the options to route traffic with Gslb?

GSLB methods

• Round Robin.
• Least Connections.
• Least Response Time.
• Least Bandwidth.
• Least Packets.
• Source IP Hash.
• Custom Load.
• Round Trip Time (RTT)

How does Gslb load balancer work?

To perform this function, a GSLB system typically monitors the health, availability, and loading for each data center; calculates client geographical locations based on their ISP DNS server address; and applies any other policies that have been configured around regulatory requirements and content localization.

How many load balancers do I need?

How many load balancers do I need? As a best practice, you want at least two load balancers in a clustered pair. If you only have a single load balancer and it fails for any reason, then your whole system will fail. This is known as a Single Point of Failure (SPOF).
