클라우드 관리자는 VMware Avi Load Balancer 리소스를 활용하여 인프라를 구축할 수 있습니다. 할당 도우미를 사용하여 Avi Load Balancer 리소스에 대한 할당 논리를 제공할 수도 있습니다.
시작하기 전에
템플릿 예제를 시작하기 전에 Automation Assembler에서 Avi Load Balancer 클라우드 계정을 생성하고, 프로젝트를 생성하고, 클라우드 영역을 추가해야 합니다. 자세한 내용은 VMware Avi Load Balancer 클라우드 계정 생성에서 참조하십시오.
단순 LBaaS 템플릿
이 샘플 템플릿은 최소 입력으로 가상 서비스, 풀 및 가상 IP 리소스를 생성하는 방법을 보여줍니다.
이 예에 사용된 모든 Avi Load Balancer 리소스는 Avi Load Balancer 컨트롤러를 가리키는 Avi Load Balancer 구조를 나타냅니다.
이 템플릿에 프로비저닝된 시스템이나 서버가 없습니다. 지속적으로 업데이트할 수 있는 서버 목록을 가져옵니다.
템플릿은 기본적으로 빈 풀로 설정되지만 실제 IP를 입력할 수 있도록 양식과 입력이 설정되어 일반 풀이 생성됩니다.

고급 LBaaS 템플릿
이 샘플 템플릿은 클라우드 영역 할당 도우미와 함께 기존 네트워크에 연결된 가상 서비스, 풀 및 가상 IP 리소스를 생성하는 방법을 보여줍니다. 또한 풀은 시스템 HTTP 상태 모니터로 구성됩니다.

간단한 웹 서버 템플릿
이 샘플 템플릿은 기존 네트워크에 연결된 가상 서비스, 풀, 가상 IP 및 2개의 웹 서버 가상 시스템 리소스를 생성하는 방법을 보여줍니다. 풀은 라운드 로빈 알고리즘을 사용하여 포트 80을 모니터링하도록 구성됩니다.
