The application server has been the centerpiece of modern architectures for web-based applications for over a decade. However, there are trends in technology that make us rethink how we use application servers and how we can get the most value out of them.
Over the years enterprises have built up considerable technical debt. This debt is made up of outdated processes, legacy applications, and stale technologies. We are all familiar with the types of headaches caused by older apps:
Development is slow.
Costs continue to rise, not fall.
Business needs are increasing in speed and complexity.
The good news are there are solutions today that solve all of these challenges. This post and accompanying video are aimed straight at helping you understand what will help you evolve your applications to a modern approach that will benefit your company and your customers alike. Using VMware and open source technologies such as Spring, Apache Tomcat, vSphere, Spring Insight and Hyperic we will explain to you how these tools and methodologies come together with tc Server to evolve your development organization and applications to tap into the full potential of lean development and cloud computing.
With the launch of the VMware Cloud Applications Marketplace just two weeks ago, VMware is adding some extra incentives for developers to join our program. Several bounties ranging in reward values from $500 to $1500 are available for both Spring Insight and Hyperic.
The Bounty Program is designed to complement the VMware Cloud Applications Marketplace, where completed and approved solutions are listed and ready-to-use. The Bounty Program, on the other hand, is a place where companies, including VMware itself, can request and reward community members for creating any original work, including plug-ins, patches, tools, specifications, documentation, or sample code. Customers and Open Source users of both Hyperic and Spring Insight are encouraged to list their own plugins in the forum. To list a bounty, you only need to be a member of the forums, which is free.

Planning the Upgrade
We know platform changes can make an upgrade more difficult and certainly raise eyebrows. So, we’ve taken measures to help make the migration as seamless and simple as possible. So far, the cases we’ve seen take about an hour. As with any data migration, the greater the volume of database records, the longer it can take. Continue reading →
VMware customers are realizing the potential for the Software Defined Datacenter (SDDC), where infrastructure is delivered as a service through automated data center management. At VMworld Europe earlier this year, we announced that vFabric Application Director was becoming part of the vCloud Suite, VMware’s comprehensive cloud infrastructure solution that integrates VMware’s leading virtualization, cloud infrastructure and management portfolio into a single SKU, placing it easily within reach of virtualization infrastructure architects to deliver private cloud Platform-as-a-Service (PaaS). Today, VMware announces three major releases that further advance customers toward making the SDDC a reality.
VMware has released an open marketplace, called the VMware Cloud Applications Marketplace, where partners, developers and VMware can easily publish and download many of the pre-built components application teams need to build their apps.
It’s been 4 years and one week since we’ve changed the first number in the application version number for vFabric Hyperic and the open source version, Hyperic HQ. In that time, a lot has happened, including being acquired by VMware. This latest release, marks the culmination of 4 years of integrating Hyperic into VMware’s processes and product lines, and establishes it as a fully integrated part of VMware’s vFabric cloud application platform.
The next release of Hyperic is coming up soon and the biggest change is to the backend. In the next release, we will only support one database, namely PostgreSQL. Those of you who have been with Hyperic for a while as long as I have may be surprised considering our history with PostgreSQL, but, as you read though this blog, it will start to make sense.
History of PostgreSQL and Hyperic
For the last few years Hyperic has supported only two databases for production use at scale—Oracle and MySQL. This in itself was a big change since at one point, PostgreSQL was our bread and butter. Hyperic was originally designed on PostgreSQL 7.x. As an open source project, PostgreSQL has a very easy license for distribution. As a startup company we had to get our product out into the marketplace quickly and affordably, so therefore PostgreSQL made sense.

Today is a new kind of birthday for me—it’s the day I started at Hyperic 6 years ago. It’s a journey that has been nothing short of surprising. My first meeting with then CEO Javier Soltero started the pace of what was to come: I had no idea it was an interview walking in, and was even more surprised when I walked out of that same interview accepting a job that same night. That sets the tone for the next 6 years.
It’s been an exciting journey riding the waves of technology changes these past 6 years, and sitting, in my opinion, in the perfect spot to see some of the biggest disruptors unfold. I have literally had the privilege to work with the most interesting companies in technology along the way. Most of the biggest companies on the web, many of the biggest companies on the stock market, and some incredibly innovative startups have used our software, partnered with us, and in two cases—acquired us. From this vantage point, I have seen some impressive changes in our industry along the way. Here are some of the highlights: Continue reading →
vFabric Suite 5.2 has been released and is now available for VMware customers to download and deploy. Considered a minor release, this update fulfills VMware’s desire to update the 13 different application components that comprise the suite every six months. The improvements across the products for this version focus on improving standardization and consistency across products, an important maintenance effort as several of the products are relatively new to the vFabric product portfolio. Customers will universally benefit from standardization across products on five fronts:
For those sysadmins who manage 24/7/365, mission-critical systems, or global operations, a “follow-the-sun” model is part of the job. But when you are NOT on duty, you would prefer not to receive any notifications. So, an important function of alerts is the ability to alert different people depending on the schedule of who is on duty. Schedule-based alerts are useful even in during a single shift as you can plan coverage for lunches, regular meetings or temporarily disable alerts to allow focused time to work on special projects.
With vFabric Hyperic, you can set-up “follow-the-sun” notifications in a few steps.
The High-Level Steps:
Essentially, to enable follow the sun alerting we simply need to set up roles and schedules for our sysadmins. However, those schedules are only useful when put in context of setting up an alert. So we will take you through the full process of setting up a globally enabled alert. Those steps include:
1. Decide on your Alert
2. Set Up the Condition and Action for the Alert
3. Set Up Roles with Alert Calendars (this specifies who gets noticed around the clock)
4. Set Up the Escalation Scheme
Today’s modern applications are built from an ever growing number of moving parts (e.g. queues, caches, services connecting different application tiers, and outgoing calls to external services). These parts are also dynamic—layers grow or shrink to scale, are load balanced, and since they are virtual or in the cloud, they can also physically move quickly. Transactions can literally pass through hundreds of different paths in your average application. These are spaghetti transactions.
Every piece of spaghetti has a start and an end, but how each one passes is difficult to see when it’s in a pile. Understanding spaghetti transactions, and how they flow between all the parts of the application’s topology has become more time consuming than ever.
Efficient management of these applications requires a new approach – moving from individually managing the health of each server, operating system, and the workload it runs, to managing applications and multi-tier transactions. Continue reading →
