High availability (HA) techniques in cloud infrastructure management are the main topic of this study since they are essential to maintaining service delivery in the modern digital economy. The requirement for strong and resilient systems has increase as a result of businesses growing reliance on cloud-based platforms. The goal of high availability is to reduce downtime and ensure that s that services and application are still available even it the event of network outages, hardware malfunctions or other unforeseen interruptions. In order to analyze various architectural strategies including load balancing, clustering, auto- scaling, and database replication, the study first goes over the basic concepts of high availability in cloud environments. It also look at the integrated features that top cloud service provides offer to help with HA projects. A realistic application that and tests a small-scale cloud infrastructure for resilience against simulated failures bolsters the theoretical foundation. The study illustrates how technology integration and strategic planning may greatly improve system stability through the use of tools like Kubenetes for container orchestration and HAPoxy for load balancing response time, recovery speed and downtime percentage.

The result show that obtaining high availability in cloud infrastructure requires proactine planning, automation and redundancy. In addition to discussing new developments like seeverless computing and AI-driven fault management which are expected to influence the development of highly available cloud system in future, the study ends with suggestions for best practices in HA design.
