SOA filling the Gaps

  More than 4 years ago I was asked if Public Cloud Core Banking is a Hype or a Short Term Reality? If you had read the post, you would probably find the answer that it was probably Hype and not Short Term Reality . This post Revisits the same issue. Size Matters The issue is a major issue for Large Banks. Those banks use IBM Mainframe for executing their Core Banking systems.  Smaller Banks used two decades ago UNIX based Core Banking Packages.  The Systems Availability, Scalability and Security was not as high as the Mainframe based Core Banking Systems, but it was probably good enough. My very limited Study I looked for real Case Studies of deployments of Core Banking system in the Public Cloud . I looked for articles and Research Notes by Googling. I did not find much. No real Case Studies of Large Banks transforming their Core Banking to Cloud Based systems. I refer to the following articles: Mckinsey's  Core systems strategy for banks   Deloitte's Cloud ...

  Ten years ago, I wrote a post titled: Cloud Computing and the Security Paradox . In this ancient post I argued that the claim of insufficient Security of the Public Clouds systems is based on a perception that what is not controlled by the Enterprise within its Data Center is less secured. However, Public Clouds Security was better than assumed  based on our perception.  Sometimes it was better than the Security of Data and Systems located within the Enterprise's Data center.  The COVID-10 magnified the Security Risks and the Public Clouds are more Secured than many Private systems. The enhanced Threats landscape   The COVID-19 Pandemic restrictions changed dramatically the way people collaborate and interact. The Security measures, Procedures, Policies and tools should be adapted to the new  interaction  style. Adaptation is a continuos Process therefore the vulnerability is higher than before COVID-19.  Main reasons for the higher vulnerabilit...

IBM's headquarter in Armonk, New York Source: Wikipedia I wrote   the first post on IBM's Survival on 2017. Issues appearing in the post were not resolved yet by IBM.  To quote my post " The problem is that IBM does not lead any significant new technologies market ." The market that IBM should be one of the Leaders is the Public Cloud market. Unfortunately for IBM, it failed to lead this market. On 2018 I wrote another post:  First Take: IBM's Red Hat Acquisition: Is it too late?   IBM's position was even worse than in 2017.  "Is it too late?" refers to the Cloud market. Like HP, few years ago , IBM plans to split its business into two companies at the end of 2021.  IBM (currently 59 billion revenues until June 30 2020) will focus on Hybrid Clouds.  "New CO" (currently 19 billion revenues) will focus on infrastructure services.  the new IBM The new IBM will focus on Public Hybrid Clouds. Mainly integrating clouds of Amazon's AWS and ...

Red Hat logo. Source: Wikipedia IBM is acquiring Software Company Red Hat for 34 billion USDs . It is IBM's largest acquisition ever. According to Business Insider some of the key points are: 1. Red Hat will join IBM's Hybrid Cloud Team as a distinct unit preserving the Independence and neutrality of Red Hat's Open Source development heritage and commitment, current products portfolio and go to ,market strategy and unique development culture.  My Take: RED Hat will continue selling its Linux Operating System and services to IBM's Cloud competitors such as Amazon, Microsoft and Google. 2. IBM will remain committed  to Red Hat's Open Governance, Open Source contributions, participation in the Open Source Community and development model. My Take: IBM is also committed to Open Source and its Cloud is based on Open Stack. with IBM's long tradition of Open Source usage and contributions it is easy for IBM to preserve Red Hat's Open Source ...

Capability Analysis Source: English Wikipedia Micro Services is a new architectural style based upon independent Services.  The terms Micro Services and Micro Services Architecture are often used. It is an architecture based on independent relatively small components named  Micro Services . Some people may think that Micro Services Architecture is a new and improved Service Oriented Architecture (SOA). It is not. Martin Fowler is the first name mentioned in articles about Micro Services. Fowler is a British Software Engineer specialized in Software development.  I read the article: Microservices in Fowler's Web site. I am more confused about Micro Services characteristics after reading the article. The article was written by James Lewis and Martin Fowler. What Micro Service Architecture is and what Micro Service is? The articles discussed the following characteristics of Micro Service Architecture and Micro Services: 1. It is a new Architectural s...

The Public Cloud is a promise. A promise for a new model without an Information Technology department.  Unlike the Public Cloud, the Private Cloud is nothing to write home about. Utility Computing disguised in modern and attractive name.  Reality is not as simple as described in the paragraphs above.  If you read the article Tectonic shift as Public Cloud giants acknowledge the private deployment options , you will discover that even Amazon and Google admit that Public Cloud is not a magical solution for all problems. There is a necessity for Private Clouds. There are systems for which Public Cloud is not adequate.  Private Cloud It is relatively easy to define Public Cloud. There are various different definitions of Private Cloud.  The main definitions could be categorized as follows: 1. Cloud which is located within the Enterprise boundaries.  Utility Computing may fit to this definition. If the organization provides Information Technol...

In previous posts such as  Cloud Computing: Hype, Vision or Reality? ,  Hyped Cloud Technologies ,  PAAS is not Mainstream yet ,  SaaS is going Mainstream ,  Future applications: SaaS or traditional?   I discussed Cloud Computing. Recently I read  Joe McKendrick 's interesting article titled: Cloud Computing Market Hot, But How Hot? Estimates are All Over the Map Joe's views and predictions are similar to mine. However, he base his opinions on actual survey done by him, as part of his work with  Unisphere Research / Information Today Inc and on leading Analyst firms predictions. I recommend reading Joe's article.  The following bullets quote few highlights: Market Research Media ,cited  in the Bloomberg report, says the cloud market will reach $270 billion in 2020. Forrester is a tad less optimistic,  predicting  last year that the market will hit $241 billion by that time.   Research firm IDC  says...
