Logs produced by your IT infrastructure contain hidden gems — information about performance, user behavior, and other data waiting to be discovered. Unlocking the value of the array of log data aggregated by organizations every day can be a gateway to uncovering all manner of efficiencies. Yet, the challenge of analyzing and managing the mountains of log data organizations have is growing more complex by the day.
Cloud adoption, application modernization, and other technology trends have put pressure on log management solutions to support a diverse infrastructure generating log data that can reach petabyte scale and beyond. As the volume of data spikes, the cost of ingesting, storing, and analyzing it does as well. Traditional log management solutions cannot keep pace with the demands of the environments many organizations are now responsible for, which forces IT teams to make decisions about log collection and retention that can hamper their ability to get the most value out of the data.
Whether they choose to buy or build their solution, the same challenges remain. The decision to develop their own solutions based on open-source tools brings new demands to allocate the engineering resources needed to maintain them. Homegrown or not, legacy architectures designed without the cloud in mind cannot handle the necessary volume of data.
This new reality requires a new approach, one that can handle the scalability, access, and analysis needs of the modern digital-minded enterprises.
A New Architecture for a New Day
Digital transformation has become more than just a buzzword; it is a concept that has touched essentially every aspect of business and IT operations. Log management is no exception. In the face of DevOps, cloud computing, and an ever-growing tsunami of structured and unstructured data, organizations have no choice but to adjust their approach to meet the needs of their increasingly cloud-first and hybrid infrastructure.
The explosion of data creates issues that cannot be solved by simply adding more storage, compute, or nodes. At certain scales, it simply becomes cost-prohibitive. The tactical impact of this reality is that it leaves insights that can be potentially gleaned from that data on the table. For example, we have seen some organizations place quotas on the logs for their DevOps teams, which can slow release cycles as developers wait for performance-related logs. This situation is a recipe for creating friction. Log management needs to be a service that reduces complexity, not an impediment to velocity or IT operations.
Increasing cost is not the only challenge facing log management for many organizations. The sheer amount of data can also make effective indexing impossible, further hurting historical data analysis and visibility. What organizations need is a way to index and analyze data in real-time and with the level of scalability they require. The larger the amount of data organizations want to regularly access is, the more capacity they will need for their hot storage tier and the higher the cost.
Object Storage Removes Scale and Cost Significant Barriers
In an ideal world, organizations would not have to make cost-driven decisions including setting quotas on what logs to send to cold storage. However, the reality many organizations face is one where compute and storage are tightly coupled, increasing the price tag attached to log management.
Separating storage and compute, however, gives organizations the scalability and flexibility to address the needs of their hybrid and cloud infrastructure. Object storage manages data as objects, eliminating the hierarchical file structure of traditional databases. Log management solutions built on top of object storage eliminate the need to manage data within storage clusters or resize it manually. Each object is organized using unique identifiers and includes customizable metadata that allows for much richer analysis. All data can be accessed via an API or UI making objects easier to query and find, and queries, reads, and writes can happen almost instantaneously.
This approach makes it easier for organizations to search out — and quickly get value from — relevant information and historical logs. The result is faster, highly optimized search queries that deliver accurate insights for high-volume log data. This capability should be further supported by analytics-driven alerting that enables organizations to proactively detect and resolve any application, infrastructure, operational, or code issue quickly. By utilizing machine learning, log management solutions can augment troubleshooting efforts by IT teams, uncovering problems by correlating and examining information about the logs in your environment.
These facts are only scratching the surface in the ways next-generation log management platforms can be transformative. Organizations need to feel secure that their log management strategy will not crumble under the stress of their IT environment. Solutions that are built using cloud-native constructs can enable each storage tier to scale up or down as needed, addressing the scalability and elasticity concerns created by the massive amounts of data from containers, microservices, Internet-of-Things (IoT) devices, and other sources.
All this, of course, must be done without compromising data hygiene. The durability of object storage is typically touted as 11 nines durable (99.999999999), which is achieved through redundancy and the use of metadata to identify any corruption. Through the use of synchronized caching, log management platforms can ensure the creation and maintenance of a single source of truth for log data throughout the environment.
Transforming Log Management
In the digital world, yesterday's solutions almost always reach a point where they can no longer solve today's problems. And tomorrow's problems? Not likely.
To address the challenges posed by today's complex IT environments requires rethinking log management for cloud-scale infrastructure. Whatever approach organizations adopt needs to deliver the flexibility and scalability necessary to deal with massive amounts of data generated. Every piece of log data can have a value if properly analyzed but realizing that potential may require IT leaders to rethink how log management is architected.
Observability has become a cornerstone of modern IT organizations, but the biggest challenge is to keep data organized so you can retrieve it efficiently. Legacy approaches have reached their breaking point. As data volumes continue to grow, the key to unlocking business value from that data will reside in adopting a strategy optimized for the cloud and the scalability needs of the modern business. Only when enterprises solve the log management conundrum will they be able to fully take advantage to improve operational efficiency, improve customer experiences to build loyalty and deliver new revenue streams to increase profitability.
