What’s New in EM4J 1.1?

Elastic Memory for Java (EM4J) 1.1 is a memory management toolkit for Java in vSphere, focused on enabling customers to confidently achieve greater memory efficiency for their Java workloads.

EM4J is a relatively new technology developed here at VMware which was created to solve the problem of memory reclamation in VMs predominantly running Java. This week, as part of the overall vFabric Suite 5.1 release, we introduced EM4J 1.1 which builds on that foundation with new monitoring capabilities in vCenter designed specifically to support Java workloads, as shown in this screenshot. First, however, if you are not familiar with EM4J, it may be helpful for a more detailed background on EM4J itself. If you are already familiar with it, you can skip to the section below on EM4J 1.1.

vFabric Usage and vFabric License Server

One change in vFabric Suite 5.1 is that the EULA now requires people to check their usage every 90 days. This is listed www.vfabric.co/eula – further below, there is an explanation on the simple way to get a report on this information:

At least once every ninety (90) days during the License Term (the ” Reporting Period”), You shall calculate, using all tools reasonably available to you, the average number of Virtual Machines in which You have run the Software during such Reporting Period (” Average Use”). If during any Reporting Period Your Average Use exceeds the number of licenses for which You have paid the applicable license fees, You shall: (i) report the excess use to VMware, within thirty (30) days of making the calculation, by providing written notice to vfabric@vmware.com; and (ii) pay to VMware, within thirty (30) days of the date of VMware’s invoice, the license fees due for such additional licenses. The day following an Average Use calculation shall begin a new Reporting Period.

The vFabric License Server makes it easy to get a quick view of license and product usage over time. The simplest way to find overall usage is to visit the web report interface. Simply enter the URL in a browser: https://host:8443/vfabric-license-server/report/create where host is the address of the computer in which you installed the vFabric License Server. You’ll see this page in your browser:

Increase performance and scalability of existing applications using SQLFire

The Challenge

Traditional databases should not be used to do things for which they were never designed; like supporting thousands of concurrent users.

The main challenge of managing Web applications on a Cloud-scale is performance. Disk-based database architectures are fine when you have a small number of users, but they lack the facilities for horizontal scaling, and, are unable to address the variable access patterns.

In contrast, SQLFire, an in-memory database from VMware, was designed specifically for these kinds of challenges. With its speed and low latency, SQLFire delivers dynamic scalability and high performance for modern, data-intensive applications, all through a familiar SQL interface.

In this post, I will demonstrate one of the ways SQLFire can increase throughput and decrease latency of your current Web applications.

Hyperic Upgrades Management of Apache Tomcat

As part of the larger vFabric 5.1 release this week, VMware’s Hyperic, the web infrastructure monitoring software bundled with the vFabric Suite, delivered on an upgrade to managing Apache Tomcat, the world’s most popular application server. As summarized in the blog post today, Hyperic upgraded support for Tomcat in three major ways:

1. Support for Apache Tomcat 7. Version 7 is gaining adoption in the marketplace, including with enterprise users. To further support this, the latest release for Hyperic adds support for Apache Tomcat 7, the latest stable release published by the Apache Software Foundation.

2. Improve Internal Use of Tomcat. Hyperic relies on Tomcat as its internal application server. The new version provides two new server configuration properties to better manage the how many threads are available to the Hyperic Server’s internal Tomcat server. The new parameters are set for deployments of less than 50 platforms, and are configurable for larger deployments to increase performance. For more details, see the complete blog post.

4 Ways VMware transforms Postgres for the Cloud

In a nutshell, relational databases weren’t built for the cloud. With vFabric Postgres, VMware customers can get a proven, enterprise database integrated with VMware virtualization and ready for cloud computing.

As announced earlier this week, vFabric Postgres (vPostgres) is now available within vFabric Suite 5.1 Advanced. With vPostgres, the well-respected, open-source database gains built in best practices, optimized configuration, and cloud-ready features.  While vFabric Postgres is synced up to PostgreSQL 9.1.3 minor release and includes all the new features of this version of the database (see PostgreSQL wiki for more), vFabric adds many features and considerable improvements in three categories:

1. Development and deployment become simpler, smarter, and cloud ready
2. Performance improvements with elastic memory and more
3. Monitoring and administration get an upgrade
4. Lower TCO and increased staff efficiency


Development and Deployment with vFabric Postgres

First, vPostgres is available in two form factors:

  • vPostgres Virtual Appliance
  • vPostgres RPMs for 64-bit Linux Servers (RHEL 6, Suse 11 sp1+)

Introducing VMware vFabric Suite 5.1: Automated Deployment, New Components, and Open Source Support

Today, VMware announced the release of VMware vFabric Suite 5.1, an integrated family of components that streamline how companies build, run and manage Java Spring applications whether on-premise or in the cloud. At VMware, we understand that smart, agile and cost-effective cloud infrastructure services are important. But ultimately, it’s about the applications that run atop that cloud infrastructure.

Demo: 7 Steps for Self-Service App Deployment with VMware Application Director

VMware vFabric Application Director is a tool for automating application deployments to infrastructure clouds – it basically automates the provisioning of infrastructure, install, and configuration processes. Once an application has been designed inside Application Director, it can also be deployed to multiple cloud environments without redesigning the application.

This blog post (and a very helpful accompanying video embedded below) will explain how Application Director’s Command Line Interface (CLI) can be used alongside VMware’s cloud stack to support a self-service portal for provisioning cloud applications.  A future blog post will outline a second key use case with Application Director – it’s use in a continuous integration development lifecycle to automate builds and migrations.

VMware software used in this Use Case:

Application Modeling in vFabric Application Director

In this video, R&D Manager Matthew Ford demonstrates for application architects and administrators  how easy it can be to do real-time application modeling with the vFabric Application Director.  Application Director supports a streamlined process to define the logical structure of virtual machines, operating systems, software, and components and create a comprehensive, graphical application model, called a blueprint.  Complete with dependency management and custom configuration, once the application blueprint is complete, the system automatically provisions the infrastructure and applications across any VMware vCloud Director registered cloud service, including public cloud services as well as private cloud infrastructures.
