Important topics for the Layer-4 vs Layer-7 Load Balancing ; What is Layer-4 Load Balancing? ; What is Layer-7 Load Balancing? ; How Does the Layer-4 Load Balancing is different from the Layer-7 Load Balancing? ; When to use Layer-4 Load Balancing over Layer-7 Load Balancing?
L4-7 load balancers manage traffic based on a set of network services across ISO layer 4 through layer 7 that provide data storage, manipulation, and comm services.
Learn about Layer 4 load balancing, how it differs from Layer 7 load balancing, and why it matters.
부하분산 또는 로드 밸런싱(load balancing) 은 컴퓨터 네트워크 기술의 일종으로 둘 혹은 셋이상의 중앙처리장치 혹은 저장장치와 같은 컴퓨터 자원들에게 작업을 나누는 것을 의미한다. 이로써 가용성 및 응답시간을 최적화 시킬 수 있습니다. 이 기술은 보통 내부 네트워크를 이용한 병렬처리(특히, 고가용성의 병렬처리)에 사용된다. 부하분산을 위한 대부분의 응용 프로그램은 다...
Security: It can offer an extra level of security to the internal structure of a network and can also prevent Distributed Denial of Service (DDoS) attacks. ; Protocol Agnostic: Differentiates traffic based on the help of IP address and port number which does not distinguish between the type of traffic. ; Web Traffic Distribution: Enables proper distribution of incoming web traffic to the multiple web servers that are available to enhance the availability and response time of the websites. ; Content-Based Routing: Filters traffic based on the content of the HTTP request which can be the path, the headers or the cookies.
Layer 4 Load balancingLayer 4 Load balancer는 TCP 연결을 양쪽에 하나씩만 유지합니다.그래서 모든 Segment들을 해당 연결로만 전달을 합니다. 1. Load balancer와 Backend 서버들간에 TCP Pool을 미리 연결해둡니다. 2. Client로부터 요청이 들어와서 TCP Connection을 합니다...
어떠한 서비스를 구축할때 우리는 대용량 트래픽을 처리하기위한 방법 중 하나로 로드밸런싱(https://aws.amazon.com/ko/what-is/load-balancing/)을 한다. 로드밸런싱을 제공 하는 요소(소프트웨어 혹은 하드웨어)를 로드밸런서라고 하며, 대표적으로 L4/L7 스위치가 있다. L4/L7 스위치의 'L'은 OSI 7Layer의...

Content-aware routing · We balance HTTP and HTTPS requests to your servers using granular content-aware routing decisions and allow you to create custom rules to route traffic using various request aspects. This lets you better support your application architecture and optimize client responses before delivery. Highly configurable · Our dynamic server functionality allows you to programmatically add, delete, or modify your servers. Instant convergence means you won’t have to wait for time-...
Layer 4 & Layer 7 load balancers base their routing decisions on different criteria. Read on to learn more about how they are different & why it matters.
