2.3 Incident Management CherryRoad offers 24×7 support to our cloud customers. All incidents and service requests must be accompanied by a ServiceNow ticket generated by the CherryRoad Help Desk. CherryRoad`s support service is the single point of contact for authorized users of the customer for incidents that involve events that cause or may cause service interruption or restriction. 1.3. “maintenance time,” the time the subscription service is not available due to service maintenance. Availability SLAs are then translated by THE IT department or service provider into affordable data loss and unforeseen downtime. Recovery Point Objective (RPO) and recovery time (RTO) are two of the main constructions of an ALS and represent these objectives. In small organizations, especially in organizations without formal regulation, you will be faced with empty looks when you ask for business for RPO and RTO times for your SDDC or Cloud solution. There is no ALS. As an architect, you have to explain these KPIs and agree with them. 2.2 Disaster Recovery CherryRoad is responsible for disaster recovery for the technology contained in the subscription service and the customer is responsible for continuous business functions. Emergency recovery is determined by a point recovery goal (RPO) and a recovery time goal (RTO).
A Service Level Agreement (ALS) is a contract between the customer, end user, department or organization and a service provider (possibly internal technical staff or an outsourced company) that describes the availability of an application, infrastructure or business. As a general rule, there are mechanisms to ensure that ALS can be met and sanctions are described if not. Service credits apply only to fees paid for the service, service or service rate for which a level of service has not been met. In cases where service levels apply to individual service resources or separate service levels, service credits apply only to fees paid for the service resource or level. The service credits granted in one month of billing for a given service or service resource do not exceed your monthly service charge for that service or service resource, if any, during the billing month. 1.6. “Recovery Point Objective” (RPO) is defined as the maximum period during which data may be lost by a service provided due to a major incident. The recovery point is determined by the time stamping of the latest backup or database protocol file that has been successfully restored or applied to the emergency recovery environment. AVAILABILITy SLAs often come with different stages like gold, silver and bronze or levels I, II and III. This allows you to differentiate your solution and take different steps. Especially within a SDDC, it is quite possible to provide different SLAs for the workloads performed in this SDDC. For example, temporary test systems generally don`t need PFTT and SFTT redundancy, so why replicate data multiple times in your vSAN cluster? Systems with built-in data replication, z.B.
databases or MS Exchange, may not require memory redundancy. Modern applications, run on sites behind a stateless GLSB, may not need an alternative to site rehabilitation at the infrastructure level.
