5 Characteristics of a Modern Mainframe Cloud App – Avoid Tornado IT

No one likes being rushed into bad decisions.

Yet, the pace of information technology often forces IT executives to do that.

In today’s world, mainframe-to-cloud decisions need solid thinking or we risk a technology tornado. This article outlines some key lessons learned at the front-line of IT decision-making.

As previously discussed, it’s possible to “modernize” mainframe legacy applications to the cloud. You can get there with little to no modification by using a “lift-and-shift” strategy.  Several of my clients have taken this approach to quickly satisfy a “cloud mandate”. The results have been less than desirable:

  • Without the use of pooled resources, the applications do not scale well.
  • Timely user provisioning and access from any device is still a challenge because the apps do not provide on-demand, ubiquitous access.
  • In addition, utility-based pricing/costing is performed manually, with little accuracy to the realities of actual usage.
  • Most importantly, the applications continue to have monolithic, stove-piped architectures, which are difficult and expensive to maintain and enhance.

These “cloud” applications are more like funnel cloud apps or tornoado apps—waiting to cause IT organizations extreme havoc. Assuming you want to avoid funnel clouds and IT tornadoes, consider applying the following five application architecture and design principles indicative of a true cloud application: Continue reading

Q&A with Shay Banon: 10 “Bonsai Cool” Things About elasticsearch

We are very fortunate to post an interview with Shay Banon, the founder of elasticsearch. Elasticsearch is technology that is very popular among some of the coolest companies on the web today, including  SoundCloud, StumbleUpon, Mozilla and Klout. These companies use elasticsearch to help them deploy powerful search capabilities in their applications that are easy to set up, scalable and built for the cloud.  In this interview, we get to learn all kinds of cool things:

  1. How Shay got into search
  2. How he came up with the idea for elasticsearch
  3. Why elastic search is different than other OSS search projects
  4. Example elasticsearch users like Foursquare, Brewster, GitHub, Sony, and Klout
  5. About the elasticsearch architecture for big data
  6. The strategy behind JSON over HTTP for search
  7. Connecting elasticsearch with RabbitMQ
  8. Connecting elasticsearch with Spring
  9. Connecting elasticsearch with GemFire
  10. Running elasticsearch on virtualized infrastructure

Without further ado, here is the interview.

Q1. So, how did you end up getting into search?
About 10 years ago, I moved from Israel to London because my wife was going to study to be a chef at the Cordon Bleu. I had no job. I was in a new country. I was unemployed. So, I started to get into the latest, cool, new technologies. Continue reading

NanoTrader: Now The SpringTrader Reference Architecture

What is SpringTrader?

Back in August, we provided a sneak peak at NanoTrader, VMware’s vFabric Reference Architecture.  It was referenced in several posts and then featured in a session at SpringOne recently.  The application has now been named SpringTrader, and we wanted to a) share more information about the SpringTrader app including some updated architecture graphics, b) provide a new tool (a version you can log into online), and c) share the location of the Spring Trader bits for download.

If you haven’t heard, the SpringTrader reference architecture is used to help Java-based application architects, developers, infrastructure, and operations teams advance their application roadmaps and provide reusable patterns.  Some might also consider how vFabric Application Director can be used with the SpringTrader app to enable continuous deployment or automatically provision and scale the app in a completely virtual data center (i.e. a software defined data center). As well, vFabric Application Performance Manager can be used to monitor the entire stack and trigger automated scaling events like adding a new JVM and tc Server to the SpringTrader app’s production environment.

Updated vFabric GemFire 7 Delivers Fast, Reliable Data at Cloud-Scale

Doubling-down on in-memory data

Download GemFire 7Memory is faster than disk. People realize that when they need to support high performance on-line applications. Recently many traditional database providers latched onto this and started “washing” their offerings with in-memory variations. At the same time, new companies are jumping into the In-Memory Data Grid (IMDG) space with unproven offerings. However, enterprise data is not something many are willing to experiment on.

VMware has virtually pioneered the IMDG, even before it was a category. Its vFabric GemFire team has been at this for a while now with a proven, production-grade offering called vFabric GemFire. In its latest release, vFabric GemFire 7.0 brings a couple of key enhancements for developers and IT pros alike:

  • Improving developer productivity
  • Increasing operational efficiencies

These improvements are in addition to the already proven data consistency and reliability that many have come to expect form vFabric GemFire in their scale-out data architectures. Once more, VMware has shown, both the technical knowhow and the necessary experience in enterprise-grade in-memory data to support on Cloud-scale.

JavaOne Architect Viewpoint: The Inexorable March toward Simplicity

Here is a quick field report from JavaOne!

We’ve talked to dozens of people, and the theme we keep hearing is simplicity, simplicity, simplicity.

Many amazingly bright application architects have stopped by to understand and learn more about the vFabric application architecture, and these folks hail from a number of industries – giant telecom manufacturers, government ministries of defense, and multi-industry service companies to name a few.

 

These conversations with architects have tended to fall into one of the falling categories: Continue reading

Powering Mobile Architecture with vFabric

Mobile is driving a lot of new application development. But, how can vFabric help?

We’ve all heard the incredible growth trends of mobile. As an example, “The Future of Mobile” presentation by Henry Blodget, CEO of Business Insider (2012), shows how mobile apps are now a $10B market and growing at 100% per year. See below.

This has led a number of companies, including Google, to adopt “mobile first” development strategies: build first for smartphones, then for laptops and desktops. At other companies, such as Urbanspoon, mobile growth is outpacing their desktop web traffic. It’s said that if Facebook were built today, it would be a mobile app.

The Mobile UI Development Dilemma

The challenge facing mobile application developers is that there are three major mobile UI technology stacks – iOS, Android Java, and HTML5 (mobile web), each with their own pros and cons. Continue reading
