Product Overview
MCCS (Mantech Continuous Cluster Server) is a High Availability (HA) Duplexing Solution for continuous service of corporate computer systems.
Service interruptions due to natural disasters, system errors, operator errors, etc. cause enormous cost losses and affect a company's social image and economic value. Additionally, planned service interruptions such as system changes and backups also incur cost losses. MCCS minimizes downtime in these situations and provides infrastructure stability that maximizes service availability by automatically restoring the same level of service in the event of a failure.
Key terms
- Resource: Minimum unit of hardware/software managed by MCCS
- Resource group: A set of resources required to operate as a single service.
- Node: Unit of cluster configuration, virtual/physical server with MCCS installed
- Two Node Cluster: A "Two node cluster" is a cluster consisting of two nodes. The two nodes are composed of an operation node and a standby node and operate like a single system.
- Single Node Cluster: A "Single node cluster" is a cluster of one node. Unlike a double node cluster, it consists of one node, so failure detection is only possible.
- Heartbeat: Communication act of transferring status information and commands between duplicated nodes
- Failover: The act of allowing the service to operate on a standby node in the event of an operating node failure.
Among the various resources that can be configured in MCCS, the three resources below are for allocating IPs that enable communication between cluster nodes to VM instances in the AWS environment.
You can register the AWS functions below as MCCS resources and detect when status abnormalities occur.
- AWS Overlay IP (OIP) Resource
This is a resource that allows MCCS to manage AWS by creating a routing destination address (Destination) on the AWS network interface with a specified virtual IP address. https://docs.aws.amazon.com/vpc/latest/userguide/VPC_Route_Tables.html - AWS Secondary Private IP (SIP) Resources
This is a resource that allows MCCS to manage AWS by specifying the secondary private IP address of the AWS network interface with the specified virtual IP address. https://docs.aws.amazon.com/vpc/latest/userguide/vpc-eips.html - AWS Elastic IP (EIP) Resource
This is a resource that allows MCCS to manage AWS by specifying an Elastic IP address allocated using the AWS Elastic IP feature to a network interface. https://docs.aws.amazon.com/vpc/latest/userguide/vpc-eips.html
