SOA filling the Gaps

Recently, I was interviewed by  Pcon   (unfortunately the link points to an Hebrew only site) as part of debriefing on Legacy Systems.  Pcon is an Israeli company investigating IT topics by quoting professional articles and interviewing experts. They publish the results of the investigations including practical recommendations. This post is mainly about topics raised by me during the interview, but not included in the debriefing, which will be published.    What are Legacy Systems? The term Legacy Systems refers to old application systems and/or veteran technologies still in use.  Usually, the term Legacy Systems is associated with: 1. Mainframe Hardware e.g. IBM System z and its Operating Systems or Proprietary Servers and Operating Systems such as HP Alpha and OpenVMS Operating System, IBM AS/400 and OS/400   Operating System. 2. Development and Production Environments, e.g. COBOL , Natural and DBMS systems such as Adabas  ...

In a previous post titled Hyped Cloud Technologies Platform as a Service (PaaS) and Infrastructure as a Service (IaaS) tied in the fourth place in a ReadWrite Cloud survey of Hyped Cloud Technologies. Yesterday, I read a Forrester Research Note about PaaS, which may explain why it is rated as one of the most Hyped Cloud Technologies.    Simply, PaaS is immature technology.  Immature technologies related to in the spotlight topic such as Cloud Computing , are natural hype candidates.     PaaS and IaaS PaaS and IaaS are related concepts: both provide technology for development and deployment of applications in the Cloud. IaaS solutions such as Amazon EC2 or Amazon S3 provide basic platform for Application Development and Application Deployment.  It is only infrastructure. Unlike IaaS, PaaS provides a complete Application Platform which includes Development Tools (e.g     Integrated Development Environment ), Runtime Environmen...

What are the most Hyped Cloud Technologies? This was the question asked in a survey of ReadWrite Cloud readers.  As no details about the sample characteristics are disclosed the results couls be misleading. The results could be biased due to some of the following factors: 1. the number of people surveyed is unknown and could be too small for supporting any conclusion. 2. The sample could be biased. Do not forget that the site is sponsored by Intel and VMware and therefore you may find relatively more customers of these companies. 3. No sample characteristics were defined, so the people answering the survey questions voluntarily may not represent the whole population. The Results The most hyped Cloud technologies were in decending order: 1. NOSQL 2. Software as a Service (SaaS) 3. Private Clouds 4-5. Infrastructure as a Service (IaaS) 4-5. Platform as a Service (PaaS) Least Hyped technologies were Infrastructure Apps and API and Data as a Service . Acco...

Seasonal Greetings to all of you. It is time to summarize 2009. As far is SOA is concerned, the most important developments in 2009 are: 1.  " SOA is dead Long Live Services" a post in Anne Thomas Mannes's blog. Anne Thomas Mannes is a Burton Group Vice President and Research Director majored in SOA. This post his blog post is important because it brought forward the mistakes in many SOA implementations and the misuse of the three letters S O A. It also catalyzed many responses of leading expert disagreeing with her opinions.  Most of the experts participated in ebizQ SOA forum agreed with me that "SOA is Dead" was important. You can read all the answers submitted to the question:  What Developments in SOA Are You Most Thankful For This Year? 2.     SOA is becomes the dominant paradigm SOA is real. The term Services is used very often. Most surveys show that at least 50% of the organizations are already implementing SOA. Most of the other en...

Created by Sam Johnston using OminGroup 's OmniGraffle and Inkscape (includes Computer.svg by Sasa Stefanovic ) I participated on December, 2nd in the first day of IGT2009 The World Summit of Cloud Computing . The interesting event is organized by T he Israeli Grid Association which organized a similar event in 2008. The event's agenda includes presentations by global vendors ( Amazon , IBM , Microsoft , eBay , Netapp , Sun Microsystems ), local companies (e.g., Matrix) Analyst ( Bitcurrent ) an enterprise ( Intel ), local and international Guru ( Yossi Vardi ). In addition an Executives Panel and workshops took place. This post does not summarize the presentations, which will be available in IGT's Web site. It is my take. Enterprise Services vs. Social Computing Most presenters talked about Enterprise Cloud Services. Yossi Vardi's message was: people are the Killing Application of Cloud Computing . He presented examples ...

This post is another post in the Vendors Survival series following posts on Microsoft , Google , HP and Sun . I read a post by Jason Hiner the Editor in Chief of TechRepublic in his Zdnet blog. The post presents 7 possible vendors' acquisitions and merges during 2009. EMC is a player in hypothesis number 1: Dell and EMC merge and in hypothesis number 2: Cisco buys Vmware . I do not think these two hypotheses will be realized. I do think that EMC management team will not make these two mistakes in 2009, if the company would like to survive until 2018. Why EMC should not sell Vmware? Jason Hiner wrote "EMC, the world’s leading storage vendor, is flush with cash and has the opportunity to make a big move". If a company has a big amount of cash, it should have a good reason for selling a company it owns. I do not find any reasonable Business Case for selling Vmware. It is true that Vmware is no longer the only leader in Virtualization functionality, ...
