Instead, enterprises manage individual containers on virtual machines (VMs). In FaaS environments, providers manage all the hardware. Alternatively, in a CaaS model, businesses can directly access and manage containers on hardware. Instead, CaaS solutions are often divided into different classes: Individual VM containers.

Streaming services, for example, run mission-critical systems in which excessive downtime could result in significant financial and reputational losses for the business. Without enough infrastructure (physical or virtualized servers, networking, etc.), there cannot be high availability. What is fault tolerance?

Defining high availability In general terms, high availability refers to the continuous operation of a system with little to no interruption to end users in the event of hardware or software failures, power outages, or other disruptions. If a primary server fails, a backup server can take over and continue to serve requests.
