Performance of Enterprise Web Applications in Docker Containers on VMware vSphere 6.5

Docker containers are growing in popularity as a deployment platform for enterprise applications. However, the performance impact of running these applications in Docker containers on virtualized infrastructures is not well understood. A new white paper is available that uses the open source Weathervane performance benchmark to investigate the performance of an enterprise web application running in Docker containers in VMware vSphere 6.5 virtual machines (VMs).  The results show that an enterprise web application can run in Docker on a VMware vSphere environment with not only no degradation of performance, but even better performance than a Docker installation on bare-metal.

Weathervane is used to evaluate the performance of virtualized and cloud infrastructures by deploying an enterprise web application on the infrastructure and then driving a load on the application.  The tests discussed in the paper use three different deployment configurations for the Weathervane application.

  • VMs without Docker containers: The application runs directly in the guest operating systems in vSphere 6.5 VMs, with no Docker containers.
  • VMs with Docker containers: The application runs in Docker containers, which run in guest operating systems in vSphere 6.5 VMs.
  • Bare-metal with Docker containers: The application runs in Docker containers, but the containers run in an operating system that is installed on a bare-metal server.

The figure below shows the peak results achieved when running the Weathervane benchmark in the three configurations.  The results using Docker containers include the impact of tuning options that are discussed in detail in the paper.

Some important things to note in these results:

  • The performance of the application using Docker containers in vSphere 6.5 VMs is almost identical to that of the same application running in VMs without Docker.
  • The application running in Docker containers in VMs outperforms the same application running in Docker containers on bare metal by about 5%. Most of this advantage can be attributed to the sophisticated algorithms employed by the vSphere 6.5 scheduler.

The results discussed in the paper, along with the results of previous investigations of Docker performance on vSphere, show that vSphere 6.5 is an ideal platform for deploying applications in Docker containers.

Introducing VMmark3: A highly flexible and easily deployed benchmark for vSphere environments

VMmark 3.0, VMware’s multi-host virtualization benchmark is generally available here.  VMmark3 is a free cluster-level benchmark that measures the performance, scalability, and power of virtualization platforms.

VMmark3 leverages much of previous VMmark generations’ technologies and design.  It continues to utilize a unique tile-based heterogeneous workload application design. It also deploys the platform-level workloads found in VMmark2 such as vMotion, Storage vMotion, and Clone & Deploy.  In addition to incorporating new and updated application workloads and infrastructure operations, VMmark3 also introduces a new fully automated provisioning service that greatly reduces deployment complexity and time.

Introducing TPCx-HS Version 2 – An Industry Standard Benchmark for Apache Spark and Hadoop clusters deployed on premise or in the cloud

Since its release on August 2014, the TPCx-HS Hadoop benchmark has helped drive competition in the Big Data marketplace, generating 23 publications spanning 5 Hadoop distributions, 3 hardware vendors, 2 OS distributions and 1 virtualization platform. By all measures, it has proven to be a successful industry standard benchmark for Hadoop systems. However, the Big Data landscape has rapidly changed over the last 30 months. Key technologies have matured while new ones have risen to prominence in an effort to keep pace with the exponential expansion of datasets. One such technology is Apache Spark.

spark-logo-trademarkAccording to a Big Data survey published by the Taneja Group, more than half of the respondents reported actively using Spark, with a notable increase in usage over the 12 months following the survey. Clearly, Spark is an important component of any Big Data pipeline today. Interestingly, but not surprisingly, there is also a significant trend towards deploying Spark in the cloud. What is driving this adoption of Spark? Predominantly, performance.

Today, with the widespread adoption of Spark and its integration into many commercial Big Data platform offerings, I believe there needs to be a straightforward, industry standard way in which Spark performance and price/performance could be objectively measured and verified. Just like TPCx-HS Version 1 for Hadoop, the workload needs to be well understood and the metrics easily relatable to the end user.

Continuing on the Transaction Processing Performance Council’s commitment to bringing relevant benchmarks to the industry, it is my pleasure to announce TPCx-HS Version 2 for Spark and Hadoop. In keeping with important industry trends, not only does TPCx-HS support traditional on premise deployments, but also cloud.

I envision that TPCx-HS will continue to be a useful benchmark standard for customers as they evaluate Big Data deployments in terms of performance and price/performance, and for vendors in demonstrating the competitiveness of their products.

Oracle Database Performance on vSphere 6.5 Monster Virtual Machines

We have just published a new whitepaper on the performance of Oracle databases on vSphere 6.5 monster virtual machines. We took a look at the performance of the largest virtual machines possible on the previous four generations of four-socket Intel-based servers. The results show how performance of these large virtual machines continues to scale with the increases and improvements in server hardware.

In addition to vSphere 6.5 and the four-socket Intel-based servers used in the testing, an IBM FlashSystem A9000 high performance all flash array was used. This array provided extreme low latency performance that enabled the database virtual machines to perform at the achieved high levels of performance.

Please read the full paper, Oracle Monster Virtual Machine Performance on VMware vSphere 6.5, for details on hardware, software, test setup, results, and more cool graphs.  The paper also covers performance gain from Hyper-Threading, performance effect of NUMA, and best practices for Oracle monster virtual machines. These best practices are focused on monster virtual machines, and it is recommended to also check out the full Oracle Databases on VMware Best Practices Guide.

Some similar tests with Microsoft SQL Server monster virtual machines were also recently completed on vSphere 6.5 by my colleague David Morse. Please see his blog post  and whitepaper for the full details.

This work on Oracle is in some ways a follow up to Project Capstone from 2015 and the resulting whitepaper Peeking at the Future with Giant Monster Virtual Machines . That project dealt with monster VM performance from a slightly different angle and might be interesting to those who are also interested in this paper and its results.

Weathervane, a benchmarking tool for virtualized infrastructure and the cloud, is now open source.

Weathervane is a performance benchmarking tool developed at VMware.  It lets you assess the performance of your virtualized or cloud environment by driving a load against a realistic application and capturing relevant performance metrics.  You might use it to compare the performance characteristics of two different environments, or to understand the performance impact of some change in an existing environment.

Weathervane is very flexible, allowing you to configure almost every aspect of a test, and yet is easy to use thanks to tools that help prepare your test environment and a powerful run harness that automates almost every aspect of your performance tests.  You can typically go from a fresh start to running performance tests with a large multi-tier application in a single day.

Weathervane supports a number of advanced capabilities, such as deploying multiple independent application instances, deploying application services in containers, driving variable loads, and allowing run-time configuration changes for measuring elasticity-related performance metrics.

Weathervane has been used extensively within VMware, and is now open source and available on GitHub at https://github.com/vmware/weathervane.

The rest of this blog gives an overview of the primary features of Weathervane.

vCenter 6.5 Performance: what does 6x mean?

At the VMworld 2016 Barcelona keynote, CTO Ray O’Farrell proudly presented the performance improvements in vCenter 6.5. He showed the following slide:

6x_slide

Slide from Ray O’Farrell’s keynote at VMworld 2016 Barcelona, showing 2x improvement in scale from 6.0 to 6.5 and 6x improvement in throughput from 5.5 to 6.5.

As a senior performance engineer who focuses on vCenter, and as one of the presenters of VMworld Session INF8108 (listed in the top-right corner of the slide above), I have received a number of questions regarding the “6x” and “2x scale” labels in the slide above. This blog is an attempt to explain these numbers by describing (at a high level) the performance improvements for vCenter in 6.5. I will focus specifically on the vCenter Appliance in this post.
