Conference Paper
Full-text available
Presentation includes the following discussion themes. – What to scale: servers, databases, containers, load balancers. – How to scale: horizontally/rightsizing, vertically, manually, automatically, ML based, predictive, serverless. – Where to scale: AWS (ASG,ECS, EKS, ELB), AZURE, GCP, K8s. – Why to scale: cost optimization, incidents avoidance,...
Conference Paper

All cloud objects (EC2, RDS, EBS, ECS/Fargate, K8s, Lambda) are elastic and ephemeral. It is a real problem to understand, analyze and predict their behavior. But it is really needed for Cost optimization and Capacity management. The essential requirement to do that is the system performance data. The raw data is collected by observability tools (...
Conference Paper
Full-text available
The research field of data analytics has grown significantly with the increase of gathered and available data. Accordingly, a large number of tools, metrics, and best practices have been proposed to make sense of this vast amount of data. To this end, benchmarking and standardization are needed to understand the proposed approaches better and conti...

Presentation was published at www.CMGimpact.com conference in 2022 and it is about the public cloud servers rightsizing method adjustment for seasonality.
Conference Paper

Commits to the MongoDB software repository trigger a collection of automatically run tests. Here, the identification of commits responsible for performance regressions is paramount. Previously, the process relied on manual inspection of time series graphs to identify significant changes, later replaced with a threshold-based detection system. Howev...

I will be presenting at CMG'21 conference https://cmgimpact.com/cloud-resources-workload-profiling/ How to be sure a cloud object’s (e.g, AWS EC2, RDS or EBS) workload fits the rightsized resources (Compute, RAM, IO/s and Network traffic)? It is very difficult to do using raw system performance data from monitoring tools. The best way to do that...

That is the presentation made in Russian for "BIG DATA and Advanced Analytics ‘20" in Minsk, Belarus (ИИТ БГУИР Минский Университет)
Preprint
Full-text available
The presentation starts with the short overview of the classical SPC based anomaly detection techniques and tools including MASF [1]; SETDS, Exception Value (EV) meta-metric based Change Point Detection [2]; Control Chart [3]; business driven massive prediction [4] and methods of using them to manage large-scale systems such as on-prem servers flee...
Presentation

The public cloud has unlimited capacity if you have unlimited budget to buy it. But if the budget is tight, one needs to do Rightsizing of the cloud objects to stop wasting money on capacity that are not used....
Presentation

The paper shares some challenges the Online Banking Capacity Management team had and overcame during the Solaris to AIX migration. The raw capacity estimation model was build to estimate AIX frames capacity needs. The Capacity planning process was adjusted to virtualized environment. The essential system, middleware and database metrics to monitor...

"This disclosure relates generally to system modeling, and more particularly to systems and methods for modeling computer resource metrics. In one embodiment, a processor-implemented computer resource metric modeling method is disclosed. The method may include detecting one or more statistical trends in aggregated interaction data for one or more i...

Capacity Management and Availability Management are two interconnected services. This connection is getting more important in the current era of virtualization, clustering, and especially cloud computing. It is obvious that IT customers want not only sufficient capacity for their applications, but even more importantly they want this capacity to be...

That is a deck for my workshop "Power of Control Charts" I ran a few times in 2009-2010 in US. The paper was written based on the workshop.
Article
Full-text available
The Control Chart is one of the main Six Sigma tools to optimize business processes. After some adjustments it is used now as visualization tool in IT Capacity Management especially in “behavior learning” products to underline performance and capacity usage anomalies. This review answers the following questions. What is the Control Chart and how to...
Conference Paper
Full-text available
Statistical Exception Detection System (SEDS) is one of the variations of learning behavior based performance analysis methodology developed, implemented and published by the Authors. This paper takes the main SEDS tools – IT-Control Chart and Exceptions (Anomalies) Detector-and shows how they can be built by Open Source type of Business Intelligen...

CMG 2009 workshop
Conference Paper
Full-text available
How often does the need arises for modeling and forecasting? Should it be done manually by ad-hoc, by project requests or automatically? What tools and techniques are best for that? When is trending forecast enough and when is a correlation with business drivers required? The answers to these questions are presented in this session. The capacity ma...
Conference Paper

The paper describes one site's experience of using Multivariate Adaptive Statistical Filtering (MASF) to recognize automatically some common computer system defects such as run-away processes on one or multiple CPUs and memory leaks. A home made SEDS (Statistical Exception Detection System) that captures any global and application level statistical...
Conference Paper

The paper describes one site's experience of using Multivariate Adaptive Statistical Filtering (MASF) to produce web-based exception reports against SAS/ITSV performance databases for a large, multi-platform environment. In addition to global exceptions, the system can capture application level exceptions by using standard workload characterization...

Thesis
Full-text available
The main idea of that work was to find the way to calculate a some set of initial grasping (or assembling) object coordinates that would warrant the successful grasping (or assembling) process (operation). I named that "Area of Normal Functioning - ANF" (Область Нормального Функционирования -ОНФ). If grasping or assembling process starts with param...
