What is LTM load balancer?
The Local Traffic Managers (LTM) and Enterprise Load Balancers (ELB) provide load balancing services between two or more servers/applications in the event of a local system failure. Global Traffic Managers (GTM) provide load balancing services between two or more sites or geographic locations.
F5® BIG-IP® Local Traffic Manager™ (LTM) helps you deliver applications to your users in a reliable, secure, and optimized way. You get the extensibility and flexibility of application services with the programmability you need to manage your physical, virtual, and cloud infrastructure.
Load balancing methods fall into one of two distinct categories: static or dynamic. Static load balancing methods distribute incoming connections in a uniform and predictable manner regardless of load factor or current conditions.

The real power of the LTM is it's a Full Proxy, allowing you to augment client and server side connections. All while making informed load balancing decisions on availability, performance, and persistence.
Last twelve months (LTM) refers to the timeframe of the immediately preceding 12 months. It is also commonly designated as trailing twelve months (TTM). LTM is often used in reference to a financial metric used to evaluate a company's performance, such as revenues or debt to equity (D/E).
F5 BIG-IP® Local Traffic Manager™ (LTM) helps you deliver your applications to users in a reliable, secure, and optimized way. By making intelligent traffic decisions that adapt to the changing demands of your applications, BIG-IP LTM ensures their consistent availability and scalability.
The LTM and GTM can work together or they can be totally independent. If your organization owns both modules it's usually using them together, and that's where the real power comes in. They do this via a proprietary protocol called iQuery.
A load balancer acts as the “traffic cop” sitting in front of your servers and routing client requests across all servers capable of fulfilling those requests in a manner that maximizes speed and capacity utilization and ensures that no one server is overworked, which could degrade performance.
Elastic Load Balancing supports the following types of load balancers: Application Load Balancers, Network Load Balancers, and Classic Load Balancers. Amazon ECS services can use these types of load balancer. Application Load Balancers are used to route HTTP/HTTPS (or Layer 7) traffic.

What is a load balancing algorithm? A load balancer is a software or hardware device that keeps any one server from becoming overloaded. A load balancing algorithm is the logic that a load balancer uses to distribute network traffic between servers (an algorithm is a set of predefined rules).
The default IP address for the TPS device is 192.168.0.1/24
Note that the Management Port supports static routing only.
F5 load balancer ensures seamless failover in cases where a server is down or overloaded. It redirects the traffic to other servers that could handle the load. HA deployment consists of two BIG-IP (like other load balancers) systems, synchronized with the same configuration: An active system that processes traffic.
An iRule is a script that you write if you want to make use of some of the extended capabilities of the BIG-IP that are unavailable via the CLI or GUI. iRules allow you to more directly interact with the traffic passing through the device.
It works by having a Virtual IP (VIP) in front of real servers with IPs (RIPs). The load balancer is the VIP and behind the VIP is a series of real servers. The VIP then chooses which RIP to send the traffic to depending on different variables, such as server load and if the real server is up.
- Go to Local Traffic >> Pools >> www_pool. Under Configuration, move the active monitor to Available.
- Go to Monitors and click on http. Click the Test tab. Under Address plug in 10.1.20.11 and in the port field plug in 80. Click Test. Go back to Local Traffic >> Pools >> www_pool.
Global Traffic Management (GTM) is designed so that Internet users can more reliably get to your websites or any other IP application. It applies an Internet-centric approach to global load balancing to provide high site availability and responsiveness to online user requests.
Lifetime maximum benefit – or maximum lifetime benefit – is the maximum dollar amount a health plan will pay in benefits to an insured individual during that individual's lifetime.
Limited Time Modes or LTMs are events in Battle Royale. LTMs feature modifications to the rules set and mechanics, such as a limited loot pool or even 50 vs. 50 combat.
What are the two types of load balancer?
Elastic Load Balancing supports the following types of load balancers: Application Load Balancers, Network Load Balancers, and Classic Load Balancers. Amazon ECS services can use these types of load balancer. Application Load Balancers are used to route HTTP/HTTPS (or Layer 7) traffic.
LTM load balances servers and also does caching, compression, persistence, etc. GTM load balances data centers. In a typical deployment, a customer will have 2 data centers, each with GTM and LTM devices. For GTM to work properly, customers delegate DNS resolution to GTM.
Load balancers improve application availability and responsiveness and prevent server overload. Each load balancer sits between client devices and backend servers, receiving and then distributing incoming requests to any available server capable of fulfilling them.
