There is an ever-increasing number of IT infrastructures making their way onto public clouds like Microsoft Azure, Amazon Web Services and Google Cloud. As this type of movement becomes more and more prominent, the importance of security tools for public clouds and centralised logs grows. It is getting to the point now where they are absolutely essential.
Performance issues in the cloud
In any cloud-based infrastructure, it is extremely difficult to reach the point of performance isolation. This is particularly true when systems are quite heavily loaded. The way virtual machines perform in the cloud can fluctuate substantially based on the specific infrastructure servers, loads, environments and quantities of active users. Consequently, issues like node failures and general reliability can become significant.
With centralised logging platforms, all of these infrastructure issues can be monitored and managed simultaneously. And this is just one feature - an ELK system for centralised logging can also process operating system logs, server logs that enable web traffic and SEO analysis, application logs and more all in one handy, centralised place.
The full power of analytics
In any context, people like system administrators, DevOps engineers, developers and site reliability engineers can all use the centralised logging system for the purpose of making better decisions based on the data compiled. The concept of 'big data analytics' is becoming an increasingly important part of all IT services for a variety of reasons, most importantly when it comes to cloud operations.
Big data is driving decision-makers in organisations of all shapes and sizes, and the future of this looks to be some sort of hybrid between on-site and cloud resources. This is why certain 'big data' frameworks are now being made to operate on the cloud as well as physical machines, and cloud analytics platforms are focusing on creating a more stable and secure environment. And with the cheaper computational power, engineers are able to create new machine-learning algorithms to perform predictive analytics in the cloud.
ELK done right
The ELK stack is a powerful tool for centralised logging. And with the implementation of a production-grade ELK stack, which requires the expertise of a professional, the power of log analysis can be unlocked. This makes centralised logging an even more essential component of a successful IT infrastructure, and one that can work to optimise and improve operations in any number of industries.
