INDUSTRY INTELLIGENCE for the end-user ' s network , the system employs special routing based on IP addresses or Autonomous System Numbers identifying specific network groups . This guides users to optimal resources , minimising latency and ensuring peak performance .
With a comprehensive tool set for load balancing and routing optimisation , CloudDNS guarantees minimal latency and enhances user experiences by swiftly providing tailored resources for users accessing ManageEngine ' s services . This commitment to performance optimisation gives ManageEngine a competitive edge in delivering exceptional online experiences worldwide .
Integrating health monitoring checks
The integrated health monitoring system of CloudDNS keeps running proactive monitoring checks at frequent intervals using various protocols , including website protocols such as HTTPS and HTTP , TCP , DNS and ICMP ( Ping ). It diligently monitors the network for active failover events from multiple vital vantage points .
Upon detecting any unhealthy resources during monitoring , the health monitor promptly updates DNS failover configurations with robust , healthy resource replicas .
This process significantly minimises latencies that may arise for the endusers accessing ManageEngine services from anywhere around the globe to the point where these latencies are either negligible or entirely imperceptible .
Dedicated VMs for latency-sensitive workloads
Resource contentions easily arise when colocated applications pathologically
The most prevalent long-tail latency challenge affecting the holistic performance of data centres manifests as an elongated spectrum of variable latencies .
compete for resources in shared environments that service multiple applications . This can cause pending transactions to take longer to complete than expected , which ultimately may be experienced as excessive tail latency .
Specifically , task mixing or coscheduling CPU-intensive workloads with latency-sensitive workloads results in instances of poor neighbouring , which contributes invariably to longtail latencies . ManageEngine deploys dedicated VMs to isolate and execute latency-sensitive workloads .
Tolerating tails over taming tails
It is possible to tame tail latencies by controlling the outliers and enhancing the workload predictability .
This can be achieved by instrumenting the data centre resources with embedded hardware and supplementary software that facilitate real-time collection and distribution of real-time debugging information along with highgranularity performance monitoring and system-wide insights .
Though it is possible to tame tail latencies with such integrated solutions that proactively prevent workload clashes without altering the core infrastructure , it is not feasible to sweep away all the sources of latencies from actively functioning data centres , like the ones hosting ManageEngine services .
At ManageEngine , its approach solely revolves around practising tail-tolerant techniques to enhance the capabilities of its data centres in addressing a wide range of latency challenges , all while delivering reliable responses for end-users . � www . intelligentdatacentres . com
