The 5 Best Cloud Logging Services in 2024

Log management can turn out to be a complex and intimidating endeavour. Things are made somewhat simpler, thanks to the availability of high-quality log management systems but, to make things even simpler and remove much of the overhead of deploying and maintaining yet another system, many administrators and managers choose to turn to cloud logging service.

But just as there are many log management systems, there are lots of cloud logging services and picking the best one for your needs can be daunting. This is why in this article we’re happy to review some of the best cloud logging services.

What are the best cloud logging services

We’ll start off by introducing log management and discuss some of the various logging technologies that are typically encountered. We’ll then talk about the differences between log servers, log management systems, and security information and event management systems. Next, we’ll discuss the advantages of using cloud logging services as compared to locally installed log management systems before we finally get to the best part, the review of some of the very best cloud logging services.

About Log Management?

Before we start discussing logging services, let’s first try to define what logging is. A log—which is also sometimes referred to as a log entry with the term log referring to where these entries are collected and stored—is the automatically-produced and time-stamped documentation of an event pertaining to a particular system. Whenever an event takes place on a system, a log is generated. Systems and devices will generate logs for different types of events and many of these will give administrators some degree of control over which events will generate a log and which won’t.

As for log management, It is the processes and policies used to administer and facilitate the generation, transmission, analysis, storage, archiving and eventual disposal of significant amounts of log data. Log management usually implies a centralized system where logs from multiple sources are collected. Log management is not just log collection, though. It is the management part which is the most important. Log management systems often have multiple functionalities, collecting logs being just one of them.

And finally, logging services refer to external providers where organizations can outsource their log management needs. They are cloud-based, software as a service (SaaS) type of business that you can use instead of locally installed log management infrastructures. There are several advantages to using logging services as we’ll see shortly. For now, just keep in mind that a logging service is nothing more than a cloud-based offsite log management system.

Once logs are received by the log management system, they must be standardized into a common form as different systems format logs differently and include different data. Some start a log with the date and time, some start it with an event number. Some only include an event ID while others include a full-text description of the event. One of the purposes of log management systems is to ensure that all collected log entries are stored in a uniform format, no matter where they come from. This will make event correlation and searching easier.

Talking about event correlation and searching, these are two very important functions of most log management systems or logging services. Some of them feature a powerful search engine that allows administrators to zero-in on precisely what they need. Correlation functions will automatically group related events, even if they are from different sources. How—but, more importantly, how successfully—different log management system accomplish that is a major differentiating factor.

Logging Technologies

Log management—both local and cloud-based—would be much more difficult, perhaps not even possible, if it were not for logging protocols. A few of them exist. They define what data is to be included in logs, how it should be formatted and, sometimes, how it is to be transmitted between systems.

Syslog is one of the most-used logging protocols, especially in the Linux/Unix world. The technology was invented in the early eighties and has become the de-facto standard for all Unix-like systems. It is also the technology that is typically favoured by most networking equipment manufacturers. One of its greatest assets is how it facilitates the separation between the system or software that generates logs, the system that stores them, and the software that reports and analyzes them. Using the Syslog technology makes log management much easier.

Other logging technologies are also commonly used. For instance, Windows uses a proprietary logging system. One reason for that is that Microsoft operating systems and applications generate logs that typically contain far more detailed information than the Syslog technology permits. Or course, any decent log management system or logging service will support multiple logging protocols and technologies transparently.

Whether you’re using a locally installed log management tool or a logging service, one of the most important deployment steps is configuring your devices to send their logs to the system. This is different from other types of tools such as network monitoring systems which can fetch data from the systems they monitor. This configuration is usually a relatively simple task which is often accomplished by issuing a simple command. Furthermore, most lo management systems and logging services will provide detailed instructions on how to do it.

Log Management vs Log Servers

Since it has been available on every Unix-like system for a while, Syslog is often used as a log server with one computer receiving Syslog data from several others. While this centralized storage of logs has definite advantages, it is not enough to be called log management.

True Log Management Systems must include at least some of the more advanced functions. According to Wikipedia, “log management is comprised of the following functions: log collection, centralized log aggregation, long-term log storage and retention, log rotation, log analysis, log search, and reporting”. On the other hand, log servers typically only offer the log collection and storage and nothing more.

What About SIEM?

Another popular technology that is associated with logs and often confused with log management is Security Information and Event Management, or SIEM. It is a closely related technology but it is slightly different from log management but the line between the two is so thin that they are often confused and some products advertised as log management systems are actually entry-level SIEM systems while some basic SIEM systems are nothing more than advanced log management systems.

This confusion stems from the fact that log analysis—a basic component of log management—is also a component of SIEM systems which are different in that they perform log analysis with the specific objective of identifying security issues. They will, for instance, look for signs of unsuccessful logins which could be a tell-tale sign of an unauthorized intrusion attempt. While some SIEM systems do include extensive log management features, others use an external log management system and it’s not uncommon to see both running side by side. If you have a SIEM system, you’ll want to pick a logging service which can work with it.

The Advantages Of Cloud-Based Logging

There are several advantages to using cloud-based logging services. They range from security to convenience and evergreening. Let’s dig deeper. One of the main advantages of cloud-based logging is security. Other than system errors and various issues, one of the primary reasons for logging is to keep a trace of all accesses to systems and data. This is particularly true when you are under attack from a hacker and analyzing logs is often one of the primary ways of detecting such attacks. Hackers know that and they will often try to cover their tracks by quickly erasing logs pertaining to their activity. With local logs, they often already have gained access to your environment so it can be relatively easy to make their presence disappear. With cloud logging, things are a bit harder for them. They’d first have to hack your logging provider to be able to delete their traces. And logging providers often have very high security.

The convenience factor is also important in the decision to use cloud logging services. First and foremost, everything is already installed. Once your account is configured, all you need is to configure your devices to send your logs to the provider. The system is always up to date, all necessary patches are always installed, you always have the latest version. We could go on forever with similar advantages.

Cost can also be a factor. Depending on your logging level, storing logs locally could end up taking up a lot of storage space and, as you know, storage space is expensive. Of course, cloud logging costs also increase as you use more storage but it tends to be a more flexible option.
