Real-time monitoring and management in monolith environments
Resource management and monitoring are important in monolith environments as well. In monolith environments, infrastructure engineers often pipe the output of Linux tools such as top, ntop, and htop to data visualization tools in order to monitor the state of VMs. In managed environments, built-in tools such as Amazon CloudWatch and Azure Resource Manager help to monitor resource usage.
In addition to resource monitoring, infrastructure engineers proactively allocate minimum resource requirements and usage limits for processes and other entities. This ensures that sufficient resources are available to services. Furthermore, resource management ensures that misbehaving or malicious processes do not hog resources and prevent other processes from working. For monolith deployments, resources such as CPU, memory, and spawned processes are capped for different processes. On Linux, process limits can be capped using prlimit:
