What cloud security platforms provide the best real-time monitoring and alerting capabilities?

Oh ! Server getting down due to high CPU/Memory utilisation, My Web-Domain SSL is going to be expired in next week......there are so many event that we need to give attention immediately and work on it. So Cloud based native services like Amazon CloudWatch ,Azure Monitor and different cloud native and open source services continuously monitor different metrics, Creates Logs of multiple event under different severity.

Azure Sentinel and AWS Cloudwatch are among the leaders of security for cloud apps, data, and networks. It is able to collect a lot of relevant information about the behavior and report them on dashboards.

AWS CloudWatch, Google Cloud Monitoring, Azure Monitor, Datadog, and Sumo Logic offer customizable, real-time monitoring and alerting for prompt security incident detection in cloud environments.

For cloud provider services, the best and sometimes only way to do "real-time" monitoring is to rely on the built-in observability tooling. For example, datadog pulls in cloudwatch metrics but these can be up to 20minutes delayed.

Creating Alert and setting Alert thresholds is challenging task for any Organisation. Need to consider Infrastructure capability, user interaction , Customer SLA, Service SLA, Budget ; Based on that need to define correct threshold . Based on metrics and as per application requirements one creates different alerts/ alarms of multiple threshold , can also creates alerts on log based metrics to identify specific event analysis. Further this will be informed to email, mobile-SMS/Call or may be integrated with slack channel.

Analysis on metrics data, recorded log and further decision plays important role in business and web analytics. We can easily integrate with incident management tool like pagerDuty, ZenDuty which aggregating and transforming data into real-time insight and action. We can also integrates various In real time, SIEM tools likes splunk, datadog are collecting, aggregating and analysing the volume of data from an organisation's applications, devices, servers or users so that security teams can detect and prevent attacks.

For real time monitoring of website or application running on cloud based platform we have multiple cloud native as well agnostic tool and custom option as per organisation needs. We can create custom dashboard which will focus on required matrix and can create alerting for multiple thresholds and could send notification to multiple stakeholders and platforms ass severity.

Scalability is biggest advantage of Cloud native platform for deployed application and websites.As per traffic /Request services scale out and scale and end user can experience seamlessly. Such autoscaling is continuously monitored under given specification and corresponding metrics gives their complete insight. If autoscaling cross it's threshold or any change in their configuration could be triggered view alerting system.
