The Future For Java Has Never Been Brighter

In this episode of the TPM podcast show Gennaro Marrazzo, a Technical Development Engineer, explains how the fragmentation of the Java platform is not a weakness, but actually one of its greatest strengths. There are flavours of Java available for everything from front-end UIs to real-time computing and mobile devices. Gennaro sees no clouds in Java’s future now that Oracle has acquired it. After all, it is in Oracle’s interest to keep Java as a vibrant development environment.

The emergence of new platforms like Python and Ruby may erode some of the niches where Java had previously flourished but Gennero believes that Java’s best days are still ahead.

Visual Studio Takes The “Integration” Of Ides Further Than Ever

In this episode of the TPM podcast show Ryan Berry, an Application Development Manager, explains how the breadth of integration in Microsoft’s Visual Studio IDE greatly simplifies the life of developers and increases productivity. When using Visual Studio Ryan can automatically file bugs, see notes from other developers, and even publish his apps to the cloud. Visual Studio features like Intellisense and XAML UI editing (new in VS 2012) take the pain out of getting things right the first time and reduce the amount of context switching developers have to go through when using lots of different tools.

Ryan is particularly happy to use Visual Studio 2012 with its closer integration with Team Foundation Server and Azure. He can easily manage his apps through the entire life-cycle, letting TFS publish his app for testing, integration with other developers and then to the Azure cloud. Ryan does point out that all this IDE automation comes at a cost. He tells about one company that ran into trouble building an app that used the .NET Entity Framework rich text field for storing pictures. The app choked under heavy load with lots of pictures loaded. The simplicity of the VS tools made it easy to walk into a problem like this, without understanding what was actually happening under the covers.

GIS and the cloud – the perfect marriage

In this episode of the Uhuru podcast show Ming Lee, the manager of on-line operations at ESRI UK, talks about the tremendous benefits his company has seen in taking their Global Information Systems (GIS) software to the cloud. By moving to virtual machines on hosting services like Amazon Ming has reduced IT costs and increased capacity to handle large amounts of traffic and processing all at the same time. Ming can spin up new machines as fast as he wants, and take them down when no longer needed. Ming has looked as Platforms as a Service (PaaS) but found that the highly customized apps he supports won’t run well on them. However, new GIS apps are being written with the cloud in mind from the start (such as not relying on the OS for state) which will enable even more productivity improvements in the future.
Be sure and check out the GIS web site Ming helped make possible that tracks Diamond Jubilee events throughout the UK, in celebration of Queen Elizabeth

The clouds are different down under

In this episode of the Uhuru podcast show Pabich Pawel, a Senior Consultant at Readify, talks about his experiences helping companies in Australia bring their web applications to the cloud. Unfortunately, the dearth of local cloud computing services often means that Australian companies have to put up with barely tolerable latencies accessing off-shore clouds. The closest Azure hosting service is in Singapore. It also doesn’t help that many of the services Pabich’s customers want, like Microsoft’s MSMQ, aren’t even available on the cloud (just try and find MSMQ on Azure).
In other respects, migrating to the cloud is no different for Australian IT professionals than anyone else. Moving to virtualized environments on the cloud is always a good first step since you can easily move existing apps no matter how messy they are that way. As more and more apps are built to be cloud friendly the Platform as a Service offerings (PaaS) become more practical. Pabich likes using AppHarbor for his personal projects. The Git integration on AppHarbor is a big plu

Creating a School of Excellence: Admissions vs. Demissions

An effective student selection process is central to creating a great private school environment, but not sufficient. When the atmosphere or social dynamics of the student body deteriorate, it is easy to point fingers at admissions, blaming them for accepting unqualified students. While admissions can make mistakes, or even take unsuccessful gambles on marginal applicants, it is imperative to have a clear process for identifying students who don’t belong and counseling them out.

Many schools count exclusively on the admissions filtering to manage the student body, excepting extreme cases like felonies on campus. When, inevitably, a few students prove themselves a nefarious influence on the student body, they must be exit, both to eliminate their influence on others and to set a clear example that such behavior is not tolerated. A school must maintain clear academic and behavioral standards and apply them consistently.

Parents who send their children to private schools are not only paying for quality academics, but for a filtered environment where their children will be surrounded by quality students. The less effective the filtering, the less value there is in paying a premium over quality public alternatives.

The same principle applies to faculty. In spite of the fact that many private schools issue annual contracts to their faculty with no extended commitment, they hesitate to ask mediocre faculty not to return. Further, as pay is often based exclusively on a combination of seniority and education levels, there is little built-in incentive for faculty to maintain their vigor after they have established themselves. As long as they perform above the minimum requirements, they can focus their extra energies on their families and personal interests. This creates an environment of mediocrity.

The pass/fail assessment of faculty is in stark contrast with the graduated grading system used habitually for students. Honors ceremonies unite the entire student body to celebrate the students who make the dean’s list and who achieve great grades, but teachers are usually only celebrated for seniority or external accolades. That sends the signal that teachers are better off conserving their energy in order to last longer and thus move higher up the salary ladder.

The majority of students and faculty respond positively to effective incentives, raising the standards of the entire school. In a school employing such incentives, performance would improve such that few students and faculty would need to leave, and they would be motivated to constantly give their full efforts.

Identifying clear values and expectations and creating consistently enforced incentives to propagate those values among both faculty and students creates an environment of excellence. Quality admissions and hiring solve only part of the solution. Quality on-going incentives within the community keep it vigorous and healthy.

Does your desktop belong in the cloud?

In this episode of the Uhuru podcast show Brian Byrne, the founder of MeshIP, tells about the benefits of running desktops in the cloud. For the same reasons that cloud computing makes sense for web servers, there are compelling reasons to run your personal productivity and desktop tools in the cloud as well. Brian’s company offers a VDI hosted solution which allows centralized management and backups. Running your desktop in the cloud might not be cheaper than buying a low cost PC for your desk, but when you add in the reliability improvements and IT management savings, the advantages of desktop hosting in the cloud are substantial.

Not all .NET roads lead to Microsoft

In this episode of the Uhuru podcast Troy Hunt, a software architect and Microsoft MVP for developer security, talks about his great experience using the AppHarbor Platform as a Service to host his .NET applications. He has looked at Microsoft’s Azure PaaS but found the requirements to rewrite his .NET apps to be prohibitive. Moreover, the AppHarbor integration with GitHub offers source control management that Troy hasn’t seen anywhere else.
The .NET PaaS takes away all the pain of having to manage servers. There is no going back to traditional hosting on virtual machines for Troy.

Is Vendor Lock-in Unavoidable When Building An App?

In our continuing series of SEP group Practical Software podcast interviews, Bishop Greg, an expert in Model Driven software projects at Inegranova, talks about how organizations building their own internal applications are increasingly finding themselves locked into particular vendors and technology stacks similar to the ‘80s and ‘90s when people were building applications on custom systems from companies like DEC and IBM. In Greg’s experience these lock-ins can be avoided by working at high level models which can be easily transposed onto varying underlying technology stacks without too much trouble. One example Greg gives is a customer of his who swiftly moved a custom app to support Web Sphere and DB2.

Maybe every organization has to bite the bullet and take a dependency on specific technologies at some point. For example, trying to build a cross-platform mobile app can sometimes wind up with software that is mediocre, not really taking advantage of any of the key features on individual mobile devices.

How do you think technology lock-in should be avoided?

RavenDB – the NoSQL database for the rest of us

RavenDB – the NoSQL database for the rest of us
In this episode of the Uhuru podcast show Oren Eini, a software developer and avid blogger, tells about his passion of bringing NoSQL database technology to Windows that led him to become a major contributor to the Open Source RavenDB project. While the NoSQL database offerings on Linux are pioneering a lot of great ideas they are inflexible and extremely difficult to configure and use. RavenDB is different. Almost anyone can get RavenDB up and running quickly and it doesn’t require an immersion in esoteric configuration settings to tune.
Since RavenDB uses simple REST APIs it can be used by any applications, whether they are on Linux or Windows. RavenDB runs well on cloud infrastructure services like Amazon Web Services and is also available in a dedicated service.

The most common mistakes in selling a cloud service

In this episode of the Uhuru podcast show Peter Cohen, the founder ofSaaS Marketing Strategy Advisors, explains how selecting the right technologies for a cloud service requires a good dose of business and marketing acumen to succeed. Picking the right technology or platform to build a cloud service is just one piece of the puzzle.
Peter has seen wanna-be internet businesses make all manner of rookie mistakes such as under spending on marketing (who knew) and selling on cost alone (you’re dead if your only differentiator  is price). Unfortunately, there is no silver bullet for success as a cloud service. Good marketing and pricing strategies will vary based on the specific business. Just make sure you are flexible and measure, measure, measure, results of everything you do.

Shadow IT and the cloud – Déjà vu all over again

In this episode of the Uhuru podcast show Brian Gracely, Director of solutions at EMC and host of the CloudCast podcast, reminisces on how cloud computing is filling the same role of empowering users as the PC and LANs did back in the ’80s and ’90s. With this phenomena of “shadow IT” developers and small departments are able to take advantage of cloud services and completely bypass traditional IT departments. All this empowerment does come with risks. Putting critical data on insecure cloud services with little traceability can come back to haunt you. There is still value in involving IT with cloud projects. Of course, forward thinking IT departments should show their users that they bring value to their cloud initiatives if they don’t want to see themselves shut out of even grass roots initiatives.
Brian also cautions that you shouldn’t expect cloud services to suddenly reduce bottom line costs. The cloud may offer unprecendented flexibility and start up velocity but they aren’t always as cheap as you think.

Cloud Foundry Bridges the Clouds

In this episode of the Uhuru podcast, Dekel Tankel, a Cloud Foundry marketing manager at VMware, explains how one of the things that interested him most about Cloud Foundry was it’s ability to cross the chasm between clouds, allowing customers to easily move their applications between cloud service providers. To Dekel Cloud Foundry is all about giving more choices to developers without locking people into a particular service or technology.
Developers can start with the Cloud Foundry micro-cloud as they build their app prototypes, running locally on a laptop, and then deploy to a cloud service when their code has matured. No other cloud service offers this degree of flexibility ranging from the private to public clouds.
At times the enthusiasm for Cloud Foundry is daunting to Dekel (they had 10,000 developers register in the first 72 hours of launch) and the volume of Open Source contributions is hard to keep up with. It would be easier to control and contain the progress of Cloud Foundry if it had been closed and followed a proprietary architecture, but it’s all been worth it.

Taking .NET to the cloud is a process

In this episode of the Uhuru podcast show Michael Collier, an architect at Neudesic, shares his experiences in bringing .NET applications to the Azure Platform as a Service (PaaS). Michael explains how migrating existing .NET apps to a PaaS is a process. Managers have to be educated about the cloud so they feel comfortable using it. He has often had to rewrite parts of the .NET apps to make them compatible with the Azure PaaS. The migration process is different for each app, depending on how it was built. .NET apps that follow best practices can run on a PaaS with almost no changes at all (e.g. not storing state on the server, etc). Other apps can be much more difficult to migrate (e.g. using COM, relying on server state, etc).
In the end, the migration to the cloud is well worth it. Developers can focus on what they love doing: writing great apps!

The Stateless App

In this episode of the Uhuru podcast Andy Piper, a Cloud Foundry developer advocate at VMware, talks about how to build great apps for the cloud. In his work with developers Andy has found that stateless apps are the easiest to transition to cloud platforms such as Cloud Foundry. Looking for particular files or settings on a server prevents your apps from being able to benefit from the automatic deployment scaling or redundancy features of new hosted Platforms of a Service. Luckily, many apps are ready to run on a PaaS already. At recent hackathons Andy has that many of the existing apps deployed on Cloud Foundry without any changes at all.

When The PaaS Isn’t Enough

In this episode of the Uhuru podcast Andrey Cherkasin tells about his decision to abandon a Platform as a Service and move to a custom hosting solution. Andrey was an early adopter of the Cloud Foundry PaaS technology, and was thrilled with being able to setup his own private PaaS. Unfortunately, Andrey’s needs for support of numerous Ruby platforms made it impractical for his needs. He now relies on a custom cloud solution using Chef Scripts and a smart OS.

The Long Path To The Cloud

In this episode of the Uhuru podcast Jason Nappi, a software developer with SmartPak, talks about the journey he has been on to move his .NET application to the cloud. Everything is now running in virtualized instances that can be easily replicated to handle additional load, but the monolithic database model used by his software doesn’t lend itself well to most cloud platforms. It would be nice to utilize the scalability possible on Azure, but that just won’t be possible without re-architecting the database. Jason is closely watching technologies like database auto-sharding to find ways to further improve the performance of his apps in the cloud.

Gimme That PaaS Source Code!

In this episode of the Uhuru podcast show Krum Bakalsky, a software engineer, shares his passion of participating in Open Source projects. In particular, VMware’s decision to place Cloud Foundry into Open Source has inspired Krum to become a significant contributor to the community effort. The Cloud Foundry community has been the perfect place for Krum to learn about the guts of building enterprise class software and to gain real experience as a participant. The fragmented nature of the Open Source world can be frustrating at times, such as when Krum discovered other programmers had already been working on something he was doing, but the collaborative environment more than makes up for these deficiencies.

Medical Imaging In the Cloud – Just a Matter of Time

In this episode of the Uhuru podcast Dr Victor Fang, a research scientist with Riverain Technology, talks about how the medical industry is well on its path to moving IT to the cloud. While medical diagnostic images (like x-rays and MRIs) are still stored locally today, most companies are looking at ways of putting them in the cloud. It has just taken a while for cloud services to reach the level of security and privacy needed to comply with government regulations. At conferences Dr Fang has attended recently he has noticed the explosion in businesses offering cloud hosting, which is just one indicator of where the medical industry is moving. Dr Fang also couldn’t help but notice that hospitals where he’s worked are typically behind in adopting stateless web applications, relying primarily on traditional Windows-based client/server solutions that are harder to move to the cloud.
The health care industry can move slowly at times, but it makes huge waves when it does move, and the cloud is just around the corner.

Everyone Needs a Cloud – Even If They Don’t Think They Do

In this Uhuru podcast episode Jonathan Schnittger, a senior developer atiQuate, talks about even companies where cloud computing doesn’t make sense for their own products can still benefit from back-office cloud services like e-mail, file sharing, etc. Jonathan’s company creates security scanning software that has to be run on local networks which precludes cloud hosting. Many of his customers are using cloud services like Amazon. Even the large enterprises he works with are hosting more and more of their applications on the cloud. Desktop replacement with cloud services is another hot area Jonathan sees organizations adopting, but the solutions for this are still immature.

Pioneer Of The PaaS

In this Uhuru podcast episode Wely Lau, a software architect at NCS Private Ltd, talks about his pioneering work with the Azure Platform as a Service (PaaS). He was using Azure as an early tester even before it was released! There have been growing pains along the way, but today Wely is building complex applications on Azure that save his customers loads of money. He describes one fascinating project where he reduced the time to process thousands of records to prioritize work for a shipping company from over 4 hours to 2 minutes by dynamically spinning up additional application instances as needed. This is the dream of the cloud – pay for what you need, when you need it, rather than having large sunk costs in systems that are only used on a periodic basis. Wely is also closely following other PaaS services such as Amazon’s new Beanstalk, and now the Uhuru AppCloud (of course!).
