What is Cloud Monitoring? Definition and Best Practices

As organizations increasingly migrate operations to the cloud —whether it's to host a website, run applications, or store data—they need a way to keep tabs on performance, security, and costs. Cloud monitoring tools offer real-time insights into these aspects, enabling administrators to identify issues before they become critical problems.

This article explains everything you need to know about cloud monitoring, best practices, benefits, and the potential challenges organizations encounter on the path to cloud maturity.

What Is Cloud Monitoring?

Cloud monitoring is the practice of tracking and evaluating all aspects of a cloud-based infrastructure. It provides insights into performance, resource utilization, availability, and costs to help businesses optimize operations and enhance security.

A vital aspect of cloud monitoring is that data is aggregated in real time. This provides IT staff with the ability to make immediate changes when and where necessary. Cloud monitoring also helps identify trends so that issues are predicted before even before they arise. Furthermore, data-driven reports help decision-makers implement changes that avoid downtime, prevent security and compliance breaches, improve user experience, and lead to better business outcomes.

Types of Cloud Monitoring

Cloud monitoring is categorized into different types based on the aspect of the cloud it focuses on. By observing, managing, and analyzing different elements of their cloud operations, companies get a detailed view of the health, performance, and security of their cloud environment.

Here are several types of cloud monitoring.

Infrastructure Monitoring

Infrastructure monitoring tracks the health and performance of physical servers, virtual machines, storage, and network devices. It measures and expresses the results of its analysis through metrics such as CPU usage, disk space, and memory utilization.

To be effective, infrastructure monitoring must be proactive. Administrators set up real-time alerts to notify them about key performance indicators and any anomalies. This automatic alerting system enables teams to resolve issues before they escalate into significant problems that could lead to downtime or degraded performance.

Network Monitoring

Network monitoring focuses on tracking the health and performance of network components such as switches, routers, firewalls, and load balancers. It is crucial for providing and maintaining network availability and reliability. Network monitoring utilizes metrics such as latency, packet loss, and bandwidth usage to detect potential problems within a network and optimize its efficiency.

Network monitoring tools are usually equipped with network security features designed to detect and thwart outside threats. These can include intrusion detection systems (IDS), intrusion prevention systems (IPS), and traffic analysis. By identifying unusual activity patterns within the network, these tools speed up response times in case of a cyber attack and mitigate potential damage.

Application Performance Monitoring

Application performance monitoring (APM) evaluates the performance of cloud-hosted software applications. It offers insights into every aspect of an application's performance, from server-side to client-side interactions, helping teams understand how their applications respond to user requests.  

APM tracks potential snags in the software stack, codes, or external services to determine the reasons for slow page loads, application update problems, or other issues that might affect user experience. Understanding how these distributed elements interact and impact application performance makes the difference between a well-functioning application and one that frustrates users and negatively impacts desired business outcomes.

Security Monitoring

Cloud security monitoring focuses on safeguarding cloud-based resources and data and is a critical component of cloud management. It goes beyond traditional security measures by providing continuous oversight of cloud environments, detecting, analyzing, and responding to potential security threats in real time.

Security monitoring identifies security threats such as unauthorized access attempts, malware attacks, and data breaches. It conducts vulnerability assessments and monitors for suspicious activity to produce a quick incident response.

In addition to real-time alerts, security monitoring provides historical data that can be essential evidence during compliance audits and investigations following a breach. Monitoring tools create a trail that shows who accessed what resource, at what time, and what actions were taken, helping organizations understand the nature and extent of a security incident. Over time, this type of historical data also identifies security trends and vulnerabilities, enabling organizations to improve their security posture through proactive measures.

Database Monitoring

Database monitoring analyzes the health and performance of databases in the cloud. It focuses on metrics such as query performance, availability, network latency, and read-and-write operations to ensure optimal database management. Other specialized metrics can be tracked, depending on the type of database used (e.g., SQL, NoSQL, or NewSQL).

A database monitoring tool goes beyond these basic benefits by tracking queries, displaying real-time usage data, and ensuring data integrity. By keeping tabs on database access requests, tracking unauthorized access and data exfiltration attempts, the tool enhances security measures.

Database monitoring also plays an important role in capacity planning and cost management. Administrators can make data-backed decisions about whether they need to scale the database vertically or horizontally by keeping track of resource utilization. This helps to optimize performance while managing costs.

Cost Monitoring

Cost monitoring, also known as cloud financial management, involves tracking the costs of cloud services and how they change over time. The metrics analyzed include data transfer costs, instance usage hours, storage costs, and costs associated with various managed services. The goal is to identify spending patterns, wasteful resource utilization, and unanticipated cost spikes.

Cost monitoring helps organizations create a budgeting plan and align cloud expenditures with their business objectives. By closely tracking how different departments or projects consume cloud resources, companies analyze costs more accurately and ensure that investment in the cloud is providing value.

Compliance Monitoring

Compliance monitoring ensures that an organization’s cloud infrastructure, applications, and data management practices follow relevant legal, regulatory, and industry-specific standards. This type of monitoring is vital for businesses that must adhere to compliance frameworks such as GDPR in Europe, HIPAA in the U.S., or PCI-DSS for companies handling credit card information.

Following these requirements not only maintains data integrity and operational efficiency within the cloud environment, it also ensures the organization avoids the penalties and legal repercussions of non-compliance. Furthermore, compliance monitoring enhances customer trust by demonstrating a commitment to data privacy and security in industries where data sensitivity is a concern.  

Storage Monitoring

Storage monitoring in cloud environments ensures that data is accessible, protected, and optimized for performance. It detects data growth, disk usage, read-write speed, and input/output operations. These metrics provide a comprehensive view of how storage resources are used. This helps administrators identify bottlenecks, anticipate capacity requirements, and optimize data placement for optimal performance.

Storage monitoring is important for both security and compliance reasons as these tools observe access patterns and file modifications. In this way, unauthorized or suspicious activities that could indicate a data breach or misuse are identified before they cause greater harm. In industries that mandate data encryption, this type of monitoring confirms if data is being encrypted both at rest and in transit.

How Does Cloud Monitoring Work?

Cloud monitoring relies on a carefully curated step-by-step solution that ensures the efficiency, security, and optimal performance of cloud-based operations.

Here are the 7 phases of cloud monitoring:

1. Data collection: Data is collected from various cloud sources, such as CPU usage, disk space, input/output speed, etc.
