Out-of-the-box dashboards for observing cloud deployments, including CPU usage, disk read/write, and network in/out.
Seamless integration with other AWS services like Lambda, S3, Athena, and QuickSight.
Capabilities to stream CloudWatch log data to Amazon Elasticsearch for real-time processing.
Cons:
Lack of memory metrics on EC2 instances in CloudWatch.
Visualization limitations out of the box, but customizable with solutions like Grafana.
Specific to AWS workloads and may not serve as an all-in-one solution for monitoring.
Usability:
Learning curve for first-time AWS users.
Effective support from AWS in addressing user queries and issues.
Support Rating:
Positive feedback on the effectiveness of AWS support, citing instances where the team provided useful recommendations for optimizing resources.
Alternatives Considered:
CloudWatch is preferred for its cost-effectiveness and seamless integration with AWS infrastructure services.
Professional Services:
Successful implementation without the use of professional services, showcasing CloudWatch's user-friendly setup.
Return on Investment:
Quick setup of log streaming, retention, and downtime alerts within a few hours.
CloudWatch's log aggregation capabilities have significantly saved time and money, outperforming some third-party solutions.
Microsoft Azure Sentinel:
Likelihood to Recommend:
Positioned as the best "cloud-native" solution for organizations with a cloud presence.
Native integration with Microsoft products, providing a single pane of glass for security monitoring.
Pros:
Native integration with Microsoft products, Azure, and Microsoft 365.
Powerful log analysis and event management using KQL and ASIM parsers.
Automation of incident response processes.
Cons:
Learning curve for installation and usage, with some challenges in connecting effectively with external PaaS systems.
Feedback on UI delays and suggestions for log display improvements.
Usability:
Easy implementation and learning curve, especially for users already within the Azure ecosystem.
Excellent support from Microsoft in assisting and solving issues.
Return on Investment:
Considered a good investment, especially when combined with other Microsoft solutions like Microsoft 365 Defender.
Provides comprehensive protection and eliminates the need for multiple platform efforts.
In summary, both Amazon AWS CloudWatch and Microsoft Azure Sentinel offer robust monitoring solutions with unique features and considerations. The choice between them depends on specific organizational needs, existing infrastructure, and preferences in terms of usability and integration capabilities.
Amazon CloudWatch is a native AWS monitoring tool for AWS programs. It provides data collection and resource monitoring capabilities. Microsoft Sentinel (formerly Azure Sentinel) is designed as a birds-eye view across the enterprise.
Azure Monitor is a native monitoring tool within the Microsoft Azure cloud platform, similar to CloudWatch in AWS. And, like CloudWatch, Azure Monitor provides monitoring for AWS and other custom data sources, on-premises data centers, and across many Azure services by default.
Azure Monitor is the native monitoring solution offered by Microsoft for Azure services. If you are a user of Azure, it is collecting data for you in the background.
Start using Microsoft Sentinel immediately, automatically scale to meet your organizational needs, and pay for only the resources you need. As a cloud-native SIEM, Microsoft Sentinel is 48 percent less expensive and 67 percent faster to deploy than legacy on-premises SIEMs.
Microsoft Sentinel is a cloud-native security information and event management (SIEM) platform that uses built-in AI to help analyze large volumes of data across an enterprise—fast.
CloudWatch Event logs describe changes in AWS resources. Some common SIEM use cases for CloudWatch logs include: Alerting when a matched event occurs in CloudWatch. Detecting any changes to security groups or network ACLs.
In general, CloudWatch charges for its Metrics service based on the number of metrics submitted to it and the frequency with which the API is called to transmit or fetch a metric. The higher your cost, the more metrics you provide to CloudWatch, and the more frequently you access the API.
The older CloudWatch Logs agent, which supports only the collection of logs from servers running Linux, is deprecated and is no longer supported. For information about migrating from the older CloudWatch Logs agent to the unified agent, see Create the CloudWatch agent configuration file with the wizard.
Azure is the finest alternative for a robust Platform-as-a-Service (PaaS) provider and even a Windows integration. If a company needs infrastructure-as-a-service (IaaS) or a wide range of tools, AWS may be the ideal option. It will be determined by the needs of the users.
CloudWatch is a secure service that offers features such as encryption of data at rest and in transit, fine-grained access control, and audit logging. Splunk provides various security features, including role-based access control, encryption, and multi-factor authentication.
What do you dislike about Microsoft Sentinel? It integrates well with other microsoft products but users find challenges when they have to integrate with non-microsoft products. Users with non technical background finds it difficult to use Microsoft Sentinel.
Azure Sentinel, renamed to Microsoft Sentinel, is a cloud native security information and event management (SIEM) and security orchestration, automation, and response (SOAR) solution that runs in the Azure cloud.
Additionally, Microsoft Sentinel includes features such as security incident management, security automation, and security orchestration. Whereas MDC is aimed at most members of an Azure administration and development team, Sentinel is intended for use by full-time information security professionals.
Sentinel (and few other modern cloud SIEM platforms) follows a different approach where - you ingest "only the logs that are needful", rather than treating it as a storage box. Logs from Log Analytics Workspace are primarily used by 3 components of Microsoft Sentinel: Analytic Rules. Workbooks.
Here are some key differences: Purpose: Microsoft Sentinel is a SIEM service that provides security analytics and threat intelligence. Azure Security Center, on the other hand, is a security management system that provides advanced threat protection and helps strengthen your security posture.
