Wdrożenie programu AWS EC2 zapewnia, że jego zastosowanie jest remasywne i że jego skuteczność jest niewystarczająca. Proper designn involves difficing resources across multiple zone and implementing failover strategies two minimize downtime.

Design Principles for High Availability

Key principles include reduncy, fault tolerance, and load balancing. Distributing EC2 invences across multiple Avavability Zone reduces the risk of a single point of failure. Load balancers direct traffic to healty instances, maintaing service continuity.

Architektury

Ta architektura typical for high vavarability involves:

  • Multiple EC2 invences in different zone
  • Elastic Load Balancer (ELB) to difficie traffic
  • Auto Scaling Groups to automatically replacee unhealty entances
  • Health checks to monitor instance status

Kalkulacje for Capacity Planning

Capacity planning involves estimating the requests per minute and each instance can handle 200 requests, at leaast five instances are needed. Adding a buffer for faisover, typically 20- 30%, preventes the count to six or seven instances.

Dodatek, consider the failover time and thee auto scaling policies to o ensure quick recovery from failures. Regular testing of the failover process helps verify the high availability setup.
