Back to Basics: Least Connections Is Not Least Loaded
When load balancing, "least connections" does not mean "least loaded"

Performance is important, and that means it's important that our infrastructure support the need for speed. Load balancing algorithms are an integral piece of the performance equation and can both improve - or degrade - performance.

That's why it's important to understand more about the algorithms than their general selection mechanism. Understanding that round robin is basically an iterative choice, traversing a list one by one is good - but understanding what that means in terms of performance and capacity on different types of applications and application workloads is even better.

We last checked out "fastest response time" and today we're diving into "least connections" which, as stated above, does not mean "least loaded."

INTRA-APPLICATION WORKLOADS 

The industry standard "Least connections" load balancing algorithm uses the number of current connections to each application instance (member) to make its load balancing decision. The member with the least number of active connections is chosen. Pretty simple, right?

The premise of this algorithm is a general assumption that fewer connections (and thus fewer users) means less load and therefore better performance. That's operational axiom #2 at work - if performance decreases as load increases it stands to reason that performance increases as load decreases.

That would be true (and in the early days of load balancing it was true) if all intra-application workloads required the same resources. Unfortunately, that's no longer true and the result is uneven load distribution that leads to unpredictable performance fluctuations as demand increases.

Consider a simple example: a user logging into a system takes at least one if not more database queries to validate credentials and then update the system to indicate the activity. Depending on the nature of the application, other intra-application activities will require different quantities of resources. Some are RAM heavy, others CPU heavy, others file or database heavy. Furthermore, depending on the user in question, the usage pattern will vary greatly. One hundred users can be logged into the same system (requiring at a minimum ten connections) but if they're all relatively idle, the system will be lightly loaded and performing well.

Conversely, another application instance may boast only 50 connections, but all fifty users are heavily active with database queries returning large volumes of data. The system is far more heavily loaded and performance may be already beginning to suffer.

When the next request comes in, however, the load balancer using a "least connections" algorithm will choose the latter member, increasing the burden on that member and likely further degrading performance.

The premise of the least connections algorithm is that the application instance with the fewest number of connections is the least loaded. Except, it's not.

The only way to know which application instance is the least loaded is to monitor its system variables directly, gathering CPU utilization and memory and comparing it against known maximums. That generally requires either SNMP, agents, or other active monitoring mechanisms that can unduly tax the system in and of itself by virtue of consuming resources.

This is a quandary for operations, because "application workload" is simply too broad a generalization. Certainly some applications are more I/O heavy than others, still others are more CPU or connection heavy. But all applications have both a general workload profile and an intra-application workload profile. Understanding the usage patterns - the intra-application workload profile - of an application is critical to being able to determine how best to not only choose a load balancing algorithm but specify any limitations that may provide better overall performance and use of capacity during execution.

As always, being aware of the capabilities and the limitations of a given load balancing algorithm will assist in choosing one that is best able to meet the performance and availability requirements of an application (and thus the business).

Cloud Expo - Cloud Looms Large on SYS-CON.TV


Cloud Expo 2013 East Opening Keynote by IBM
In this Cloud Expo Keynote, Danny Sabbah, CTO & General Manager, Next Generation Platform, will detail the critical architectural considerations and success factors organizations must internalize to successfully implement, optimize and innovate using next generation architectures.
Lisa Larson, Vice President of Enterprise Cloud Solutions of Rackspace Hosting Live From New York City
In the old world of IT, if you didn't have hardware capacity or the budget to buy more, your project was dead in the water. Budget constraints can leave some of the best, most creative and most ingenious innovations on the cutting room floor. It's a true dilemma for developers and innovators – why spend the time creating, when a project could be abandoned in a blink? That was the old world. In the new world of IT, developers rule. They have access to resources they can spin up instantly. A hybrid cloud ignites innovation and empowers developers to focus on what they need. A hybrid cloud blends the best of all worlds, public cloud, private cloud and dedicated servers to fit the needs of developers and offer the ideal environment for each app and workload without the constraints of a one-size-fits-all cloud.

Keynote: Driving Cloud Innovation: SSDs Change Cloud Storage Paradigm
Cloud is a transformational shift in computing that can have a powerful effect on enterprise IT when designed correctly and used to its full potential. Join Citrix in a discussion that centers on building, connecting and empowering users with cloud services and hear examples of how enterprises are solving real-world business challenges with an architecture and solution purpose-built for the cloud.

What do you get when you combine Big Data technologies….like Pig and Hive? A flying pig? No, you get a “Logical Data Warehouse.” In 2012, Infochimps (now CSC) leveraged its early use of stream processing, NoSQLs, and Hadoop to create a design pattern which combined real-time, ad-hoc, and batch analytics. This concept of combining the best-in-breed Big Data technologies will continue to advance across the industry until the entire legacy (and proprietary) data infrastructure stack will be replaced with a new (and open) one.
While unprecedented technological advances have been made in healthcare in areas such as genomics, digital imaging and Health Information Systems, access to this information has been not been easy for both the healthcare provider and the patient themselves.

Everyone talks about a cloud-first or mobile-first strategy. It's the trend du jour, and for good reason as these innovative technologies have revolutionized an industry and made savvy companies a lot of money. But consider for a minute what's emerging with the Age of Context and the Internet of Things. Devices, interfaces, everyday objects are becoming endowed with computing smarts. This is creating an unprecedented focus on the Application Programming Interface (API) as developers seek to connect these devices and interfaces to create new supporting services and hybrids. I call this trend the move toward an API-first business model and strategy.
We live in a world that requires us to compete on our differential use of time and information, yet only a fraction of information workers today have access to the analytical capabilities they need to make better decisions. Now, with the advent of a new generation of embedded business intelligence (BI) platforms, cloud developers are disrupting the world of analytics. They are using these new BI platforms to inject more intelligence into the applications business people use every day. As a result, data-driven decision-making is finally on track to become the rule, not the exception.

It was just two years ago, in March of 2013, that the PaaS company dotCloud decided to open-source its container technology under the name "Docker." Docker quickly became a hit, with Docker Meetups spawning weekly worldwide and downloads occurring at record-breaking rates. The dotCloud team quickly changed direction, renamed the company "Docker," and brought in new CEO Ben Golub in July 2013 to lead the new business model. At the time, Docker was about a twenty-person company. Fast-forward to today, and Docker has north of 120 people, has made a handful of strategic acquisitions, and has integ...
What’s hot in today’s cloud computing world? Containers are fast becoming a viable alternative to virtualization for the right use cases. But to understand why containers can be a better option, we need to first understand their origins. In basic terms, containers are application-centric environments that help isolate and run workloads far more efficiently than the traditional hypervisor technology found in commodity cloud Infrastructure as a Service. Modern operating systems (Linux, Windows, etc.) are made up of two basic parts: kernel space and user space. As its name implies, Kernel space ...
Those from a dev-centric background might discount monitoring from their DevOps approach. But if you're already automating deployment and testing, why wouldn't you use the right set of tools to avoid manual performance monitoring? Of course, you do performance tests each time you release changes to pre-production. You're checking for response time, processor utilization, memory occupation, I/O activity and so on, but how can you ensure normal behavior without a reference point? In other words - despite your good intentions - aren't you using critical production as a first level of benchmark? ...
We’re living in exciting but demanding technological times. Big Data, Internet of Things, Apple Watch, ubiquitous computing, smart machines, robotics, and home automation . . . things that were the talk of science fiction only a few short years ago are on every CIOs wish list today. But to the point, the revolution in technology has led to major shifts in how organizations today ideate, plan, develop, and deploy software solutions. It used to be that software release cycles would take upwards of 18-24 months or more. Now, with the innovations spurred on by the consumerization of IT and heighte...
John Zachman, Chairman and CEO of Zachman International, and originator of the Zachman Framework, examines the role and benefits of how EA frameworks can co-exist well.

And what should organizations do as they seek a best approach to operating with multiple EA frameworks?
SDN is a still simmering trend. It's not boiling over like cloud did in its early years but rather it's slowly, steadily continuing to move forward as more organizations evaluate, pilot and implement pockets of SDN within their organization. stage of sdn deployment 2015 But it's not all rainbows and unicorns. A mere 8% of organizations in our State of Application Delivery 2015 reported having SDN deployed in production. Another 8% were in their initial implementation, but a whopping 43% had no plans to deploy at all.
I recently wrote about how Amazon’s new Dash service embodies the Stackato vision; in that post I discussed how Dash reflects the Business Agility portion of our vision. As the image to the left shows, Dash is a service that offers a small button; when pressed, magic happens and an order is placed for the product (in this example, Tide detergent), which is eventually delivered to the customer. Dash presents a very different model of retailing, changing the purchase execution from a physical retail outlet or an online website to the very location of product consumption. With this service, Ama...
Last week we announced the release of “Enabling the Future of Applications: The Stackato Vision.” This video describes how the nature of information technology is changing – from automating business-supporting processes to being the business offering itself. Using IDC’s Third Platform concept as a framework, we identify the critical success factors necessary to be a Third Platform company and present examples like Uber and Airbnb. If you’re not familiar with IDC’s Third Platform, it represents the confluence of four technology trends – social, mobile, Big Data, and cloud computing – that in ...
This is a no-hype, pragmatic post about why I think you should consider architecting your next project the way SOA and/or microservices suggest. No matter if it’s a greenfield approach or if you’re in dire need of refactoring. Please note: considering still keeps open the option of not taking that approach. After reading this, you will have a better idea about whether building multiple small components instead of a single, large component makes sense for your project. This post assumes that you have experience with software architecture and services (you’ll find some words about my experience...
Dorothy the CIO was walking the yellow brick road of planning. She was on her way to the Emerald City to ask the great wizard of the agile data center for advice. Along the way she met two other CIOs who joined her on the journey, nicknamed Tin Man and Scarecrow. Their travels brought them to the edge of the dark forest of datacenter hype and fear. ‘‘Do you think we’ll meet any wild technologies and fears in there?’’ she asked her companions. ‘‘We might.’’ responded Tin Man. ‘One’s that devour IT projects?’’ whispered Scarecrow. ‘‘Possibly.’ said the Tin Man, ‘‘but mostly containers, an...
In this 4-part blog series, I am exposing DevOps best practices using a metaphor inspired by the famous 6th century Chinese manuscript: “The Art of War.” It is worth reminding that Sun Tzu, just like me, considered war as a necessary evil, which must be avoided whenever possible. What are we fighting for here? Ultimately, we’re fighting for the absolute best services and features that we can deliver to our customers as quickly as we possibly can, and to eliminate the “War Room” scenario we are all so familiar with.
Online tax companies go from an absolute standstill to 100 mph in a matter of days. How do these companies do it? Tax laws change every year, so that online application is basically a brand new release when users start pounding away at it in February. What is it like to test the performance of a website that sees a higher traffic spike than an eCommerce site on Black Friday – with no warm-up period preceding it? How do they get performance right the first time that they face an onslaught of users?
As we approach the next @ThingsExpo, to be held June 9-11 at the Javits Center in New York, my thoughts naturally turn to the Internet of Things. The IoT is a leviathan—in the best possible sense of the term—that will sweep up most everything in the ocean of data and technology being created today and tomorrow. But rather than try to grasp all of its possible uses, for today I'm looking at “just” the Industrial Internet part. I just read a long paper co-authored by Tim Berners-Lee about the possibility of describing a “web science,” that is, discipline that combines the study involved ...
Infrastructure and Operations Management may seem like just so many blinking lights in the back room, as parallel shadow projects are launched by department heads who can't wait on IT. Today, these shadow projects are more prevalent than ever as more non-tech managers look for easy access to tech functionality.
