We design systems with redundancy and built-in failover mechanisms. Depending on the goals and budgets, we utilize a wide range of logic and hardware solutions to ensure the requested uptime. For regular projects, we successfully utilize out-of-the-box tools provided by Azure, AWS, or Google. Commonly, it's enough to ensure less than an hour of downtime monthly, which is suitable for 99% of websites and applications. For more complicated products, that require even more redundancy, our DevOps team utilizes tools such as Azure Availability Zones spreading the workload between several physical facilities with independent technical maintenance, preventing downtime caused by physical damage to data centers. Then, if anything happens, we leverage backup vaults and other powerful recovery solutions to restore normal work as soon as possible. If you still have any questions about building the infrastructure that can withstand literally anything, from hacker attacks to natural disasters and even alien invasions, talk to our DevOps experts!
