The average data center may already appear to be heavily automated. In one sense, this is accurate. Many of the common operations carried out in a data center have already been configured in standard ways such that the network will function smoothly without human intervention.
In another sense, however, many data centers do need manual fine-tuning on a regular basis. Tasks that are essential to good network management such as disaster recovery as well as ongoing maintenance and provisioning are often done through manual intervention. In some businesses, in fact, any change to the standard configuration must be done manually.
Some of these needed changes are predictable, however. Intervention tasks such as adding on new services, changing passwords, or altering a routing table can be automated so that less human intervention is required. A managed services model for IT support is one that generally takes advantage of additional levels of automation so that costs can be as reasonable as possible for the service.
Businesses can automate more processes on their own, but allowing a computer to make changes by itself can be quite tricky. Great experience and expertise is needed to avoid a situation in which automated changes actually cause havoc. For this reason, it is preferable that additional automation takes place in the context of an overall managed services model because this approach guarantees that personnel highly experienced in automation will be the ones to implement it.
Like many issues in IT, automation is best performed by experts.
