Whitepaper The 3 Things You MUST Get Right with Cloud Management to Avoid Dysfunction Replication Charles Araujo Principal Analyst, Intellyx April 2020 Sitting in on a tech company sales pitch these days can seem a little bit like a scene from My Big Fat Greek Wedding — no matter what your ailment, Cloud (instead of Windex) is the answer! In fairness, there's no question that the cloud is already a significant part of the enterprise technology stack and will play an even more substantial role in the future of any enterprise IT function. Still, the pervasiveness of cloud adoption does not come without a healthy dose of irony. While much of the pitch about anything cloud-related focuses on its inherent modernity, and with it, the implication that it will solve IT’s dysfunctional woes of the past, cloud management practices are increasingly replicating those very dysfunctions. Far from realizing a holistic management purview of their newly cloudified technology assets, enterprises are, instead, creating a whole new host of management silos. Cloud performance monitoring, one silo. Cloud cost and bill analysis — another. And capacity and workload management? Most organizations aren’t even scratching the surface of that one. 3 The 3 Things You MUST Get Right with Cloud Management to Avoid Dysfunction Replication When cloud initiatives were in their early let’s-test-this-and-see-what- happens modes of operating, this situation was all manageable enough. All it required was a little elbow grease. That’s no longer the situation. If enterprise leaders do not want to replicate the dysfunctions of the past, they are going to need to take a fresh look at cloud management — and make sure they get these three things right.

A vital component of cloud management is the migration of workloads from traditional, on-premises environments to the cloud. And, this is the first place that many organizations start to go off the rails. At the very beginning of the shift toward cloud architectures, there was often very little analysis — if any. In part, this was because many initial cloud workloads were for so-called greenfield applications. They were brand spanking new, so there was little analysis to be done. As organizations began moving production workloads to the cloud, however, complications almost immediately arose. Operations leaders responded by doing some superficial analysis, but as cloud deployments mature and grow, that's proving to be insufficient. While the first cut at analysis was adequate to keep cloud migrations from crashing and burning, the lack of in-depth analysis often served to bury the problem, making it that much harder to surface later on. ©2020 Intellyx LLC. https://intellyx.com 5 The 3 Things You MUST Get Right with Cloud Management to Avoid Dysfunction Replication The first thing that organizations need to get right if they are to avoid cloud management dysfunction, therefore, is workload rightsizing — and they need to get it right at the point of migration. To do so, you must dig deeper and analyze the full-stack resource utilization of your target workloads. This analysis should include CPU, memory, I/O, network, and storage — and with enough depth and granularity that it will enable you to do comprehensive what-if analysis as you assess your deployment options. Most importantly, you need to adopt a workload-centric perspective — rather than a systems-centric perspective — as you employ this analysis. Not all workloads are created equal. This fact is particularly important as you attempt to strike the right balance between performance and cost optimization during cloud migrations. Likewise, as you complete this full-stack analysis and seek to rightsize your target environments accordingly, you may find that not all workloads are, in fact, viable targets for a cloud migration, or that you should prioritize and sequence migrations differently. The point is that an effective rightsizing capability will allow you to approach cloud migrations with your eyes wide open — a sure way to minimize dysfunction down the road.

While moving a workload to the cloud comes with many benefits, it also brings a set of challenges. Ironically, many of those challenges are a direct function of the benefits the cloud offers. The ability to configure cloud environments in countless ways and employing so many different and nuanced configuration options gives the enterprise immense flexibility and agility — but it also makes the job of monitoring and optimizing those deployments a significant challenge. The ability to configure cloud environments in countless ways and employing so many different and nuanced configuration options gives the enterprise immense flexibility and agility — but it also makes the job of monitoring and optimizing those deployments a significant challenge. To add fuel to the fire, most of the configuration options exist on each of the various public cloud providers — but each provider has implemented and configured them in different ways. As most organizations have adopted a multi-cloud strategy, that means that you must stay up-to-date on these countless configuration options across these different platforms. ©2020 Intellyx LLC. https://intellyx.com 7 The 3 Things You MUST Get Right with Cloud Management to Avoid Dysfunction Replication While this complexity is a challenge from a broad management perspective, operations Achieving this type of holistic teams that are responsible for monitoring and operational performance optimizing cloud workloads may feel it most acutely. management demands that you move beyond simple reports and It is imperative, however, that organizations get operational performance right if they are take advantage of advanced to avoid replicating the dysfunctions of the performance management past and, instead, manage their cloud approaches. environments as part of a cohesive hybrid strategy. Achieving this type of holistic operational performance management demands that you move beyond simple reports and take advantage of advanced performance management approaches. These approaches should allow you to bring together sophisticated detection techniques with the appropriate context to enable you to assess the situation in this dynamic environment more accurately. For instance, some modern cloud management systems are leveraging advanced anomaly detection techniques and pre- configured alerting policies (based on industry best practices) to identify potential performance problems in cloud environments. They are then adding context to allow operations leaders to readily assess the situation. ©2020 Intellyx LLC. https://intellyx.com 8 The 3 Things You MUST Get Right with Cloud Management to Avoid Dysfunction Replication An example of this contextual analysis is the detection of an increase in CPU cycles. By itself, it may be insignificant, but if an increase in the number of processes waiting for CPU cycles accompanies it, it is much more likely to indicate a performance issue. Most importantly, organizations must build an operational performance management capability that is optimized for the various configuration options in the cloud, that allows for the cloud's dynamic nature, and which is application- centric in its foundation. The goal of this performance management capability must be to integrate into the existing operational management model, provide visibility to potentially impacted operational teams, and enable automated scaling (when possible) to maintain workload performance and avoid application disruption.

While those configuration options offer organizations all the flexibility and agility they seek, each option also comes with different cost attributes. This fact makes balancing operational performance and costs a delicate and intricate dance. Adding to the challenge, this dance is something for which most enterprises are ill- prepared. On-premises environments have generally represented sunk costs. An organization made a substantial investment in a technology stack. As a result of that tremendous up-front investment, configuration
