Chapter 4. Service Scheduling and Management Frameworks
This chapter introduces several Mesos-based scheduling and management frameworks or applications that are required for the easy deployment, discovery, load balancing, and failure handling of long-running services. These so-called metaframeworks take care of the housekeeping activities of other frameworks and applications, such as service discovery (that is, keeping track of the instances on which a particular service is running) and load balancing (ensuring an equitable workload distribution among the instances), apart from configuration management, automated job scheduling, application scaling, and failure handling. The frameworks that we'll explore here include:
- Marathon: This is used to launch and manage long-running applications on Mesos
- Chronos: This is a cluster scheduler
- Apache Aurora: This is a framework for long-running services and cron jobs
- Singularity: This is a platform-as-a-service (PaaS) for running services...
