21) Is Big Data only for large enterprise? How do small enterprises leverage Big Data?
Whether you run a small business with just a few employees or you a large multinational enterprise you can benefit from big data. The constant stream of data flowing to and from us through everyday devices and products generates more market data than ever before. The amount of data we’re producing is growing at an incredibly rapid rate. In less than five years from today (2015), experts predict that our annual data creation will be in excess of 45 trillion gigabytes. With the amount of data available to individuals, corporations, and governments, there is no question that your business needs a Big Data Strategy.
When we say Big Data Strategy what is required is a focused, data-driven strategy that will not just collect information but to use that information in the most effective ways possible to help your business overcome existing business challenges but also help improve your bottom line.
To define your Big Data strategy you should first have answers to these questions.
1) What is the biggest challenge for my enterprise/business today?
2) How can I know my customer better?
3) If I have better understanding of my data will it help to address business challenges?
4) How can I use analytics to get insights about my customers and their buying and spending patterns?
Once you have answered these questions you know what is the expected outcome of your BD Strategy and then you shall be able to define the strategy for Big Data for your business (you might take help from an expert). Big Data is not just for big businesses with huge amount of data and it can help small business to strategize and increase their customer base and retain customers.
Take this example of a family owned small company that helped tourist find cheap and comfortable accommodation with homeowners. Company helps around 700+ homeowners to generate additional income by renting their spare rooms. The small company used an analytics tool to tap into data ranging from spreadsheets to databases and make the analysis available to home owners and contractors. The predictive analysis helped company save a large amount of money by better planning and demand/supply management. The company had expected the Big Data spending to provide returns in 3 years but they realized returns in 2 years. There are many more examples and I will share few of them in coming days.

20) Tackling Top Telco Fraud's with Big Data and Complex Event Processing - Part- II
I am going to share a sample architecture that will help implement solutions to prevent fraud. The architecture combines Big Data technologies with Complex Event Processing (CEP) to provide a Smarter, Proactive system along with a Dashboard that will 'show relevant fraud events or potential fraud events' which will help prevent fraud.
The high level diagram of the Big Data-Complex Event Processing solution is self explanatory and the key points to be noted are :
1) Technologies & products implemented in sample solution
2) Real Time Architecture to handle large amount of data
2) The way data in ingested, filtered & crunched
3) The way events are 'acted on' on-the-fly
4) The operations dashboard that will provide alerts and notifications so manual checking will be reduced
5) How analytics is going to be plugged into this architecture
Please feel free to mail me if you have questions.

19) Tackling Top Telco Fraud's with Big Data and Complex Event Processing - Part- I
Those of you who have not worked for a telecom company would be surprised to learn about the 'different type of fraud' faced by the telecom industry. Frauds are biggest cause of revenue loss to telecom companies and in general the top 5 types of fraud that a telecom faces are as follows (priority might differ for different telcom companies)-
2) Subscription Fraud Using Fake Identity:
Subscription fraud involves the acquisition of telecommunications services using stolen or false credentials and/or identity with no intention of paying. With subscription fraud, service providers lose revenue.
3) Roaming Data Fraud :
Delay in getting Customer Roaming Call Data from roaming partner to home network paves the way for fraudsters to make roaming calls resulting in financial loss for the CSP, which is categorized a roaming fraud.
4) Internal fraud activity :
Internal manipulation of the system, Account adjustments via Voucher Administration Terminal & Tampering with billing/rating systems are frauds that can be done by people who have access to systems
5) Frauds related to prepaid telecom services:
A retail agent or call center agent may attach a value-added service (VAS) to an unsuspecting subscriber. For example, a ringtone can be added without the customer’s knowledge or permission, resulting in a commission for the agent. Currently there is no effective means to analyze the data and detect such kind of fraud.
1) Sim Card Cloning Fraud :
Fraud happens because there is no efficient way to check cloning, CSP have to perform manual checks to detect cloning, not efficient2) Subscription Fraud Using Fake Identity:
Subscription fraud involves the acquisition of telecommunications services using stolen or false credentials and/or identity with no intention of paying. With subscription fraud, service providers lose revenue.
3) Roaming Data Fraud :

18) Telcos, challenge of Big Data & even Bigger Challenge of Telecom Fraudsters
Big Data brings an interesting set of technologies like Hadoop, Sentiment Analytics, Predictive Analytics. Big Data also brought a new generation of solutions. The only challenge as I have mentioned before is that technology & business need to sit together to analyze and identify the 'right' use cases before investing in Big Data.
I have implemented Complex integration solution for telcom companies and realized that telco is a world by itself. An outsider will never realize the complex working of a telco and the huge volume of data that they generate! Telcom companies have always been in forefront of adopting latest technology innovations and rightly so. The ever growing customer base & network of Telco world generates humongous amount of data. Telcos requires their software to crunch data faster, filter out the noise & process faster. Big Data makes way for Distributed Data Processing hubs for various Telco use cases. I am listing a few use cases that I have discussed with some of the top think tanks and innovators of Telcos.
One of the biggest challenge faced by telecom companies is fraud. Telecom companies loose more money to fraud then one can imagine. The fraudster use innovative technology to commit fraud so to detect and prevent fraud we need to use Predictive Analysis coupled with Big Data Processing on the large data generated by each phone, each switch, each tower, every second.
1.Telecom fraud is estimated at $40 B globally and it is the single biggest cause of revenue loss for operators, costing them between 3% and 5% of their annual revenue. With rising competition & extremely low average revenue per user (ARPU), detecting fraud and plugging revenue leaks have become extremely important to reduce costs.
2.One study reports that the internal fraud (40.3%), roaming fraud (11.4%), pre-paid (10.8%), subscription (11.6%) and premium (13.1%) are the most important in terms of losses by values.
3.Fraud connected to prepaid accounts is much easier to commit and harder to combat, since there is very little information on the subscriber, unlike postpaid accounts, where a credit check is usually done. Entry-level fraudulent activities such as subscription and impersonation are very serious since the cost is coming straight from the bottom line in the form of commissions and incentives.
4.The fraud management becomes more and more important as the new methods of access become available such as Cable networks, Wireless networks, DSL, Satellite, Metropolitan Optical Networks running Ethernet, Broadband Wireless Systems (radio, microwave, or infrared).
5.Although there is an abundance of data generated by mobile devices and systems a large amount of data is not processed in real time.
6.Telco would like to detect critical events and patterns across all its data sources in real time, perform advanced in-memory analysis in real time and take preventive or corrective action in real time to providing better service to its customer and reducing the financial looses

'Google Now' Commands that you should try on your Android Phone : Tried & Tested
As most of us are aware the command 'Ok Google' on an Android phone invokes an interactive voice assistant that can understand a vocabulary of commands. So when you
pick up your Android phone and say “OK Google” your phone goes in a listening mode and you can do things without touching the phone. So what do you say to your
phone? What can you say to your phone? What all can Google assistant do for you?
I tried exploring the commands and here’s a list of just about everything you can say to Google Now. Another interesting thing, if Google Now doesn’t get your spoken commands right, you can correct it by saying “No, I said...” and trying the phrase again. The text in braces [] can is not part of the command and can be changed to customize the command.

17) Smarter Border Security using Big Data
I have worked on designing Big Data solutions for various industries. My area of particular interest has been Border Security Solutions. There is immense scope to improve the border security solutions by use of various traditional & Big Data sources & make the security solutions smarter, more robust & predictive.
Any country's border can be penetrated by land, air & water through legal and illegal means. So a border security solution needs to consider more non-traditional data sources apart from the existing data sources.
1) Collection of critical surveillance data using sensor technology - Today various types of sensors, videos camera and connectivity solutions have become far more affordable and the data can be collected remotely, transmitted to a central server and processed in a speedy manner to get insights into various security factors that need to be analyzed for security of borders.
2) Telecom Data- Call Data Records, Tower Data & User Data from telecommunication providers can be monitored and analyzed for identifying and tracking 'potential security threats'.
3) Voice & Data Analysis - Analysis of voice & data in the border areas can provide information about potential threats and breaches in the border area and most of the borders area already use this data for intercepting threat
communication.
4) Social Media Data- Analysis of data from social-media, blogs and internet call services can help in identifying discussions and profiles that could be involved in objectionable activities related to border areas.
5) Transport Data - Knowledge of vehicle owners & tracking of vehicles in the border areas can provide additional data that can be related to various security breaches and identify any new vehicle in the area. Will this information a mechanism can be defined to sanitize vehicle moving in and across borders.
6) People Data - Biometrics data of the residents of border areas should be used to identify 'new people' who have moved in the area. People movement along with various other threat data can be used to identify security threats and also help predict potential security breaches in border area
7) GPS data is collected by border security agencies and used for various objectives. A big Data solution can help analyze the GPS data to potential security threats as well as to help position security personal on the border thus enabling optimum use of security infrastructure
) Finally Big Data Analytics of the said data sources should help build a comprehensive analytics dashboard that can be used by border agency as well as the security personal that protect the borders using hand held devices. I would like to discuss Big Data Analytics and Mobile devices in more detail because this is one of the fastest growing areas of Big Data & Mobile.

What are the SOA Design Patterns every architect should know?
When I meet architects and developers at different forums I see some people consider SOA to be a independent optional discipline. The fact is tears back there was a time when concept of SOA was new and people had to decide if they should do changes to their application to make them SOA compliant. Today we are convinced about the benefits of SOA and it is defacto design principle. I would go to the extent of stating that if you are not following SOA Principles when designing and coding applications i any technology, any programming language then you are doing something very wrong.
My past employer Accenture was a pioneer in SOA implementation and innovation for SOA. I got opportunity to lead the SOA Practice, work with industry leaders and implement multiple projects as a SOA Architect for some of the top clients. The best way to learn is to implement solutions for the most demanding fortune 500 clients and I was fortunate to get the opportunity as the lead SOA architect for Accenture. One of my innovations SOA Service Bench won 1st prize in Accenture wide innovation contest and I was honored by Accenture CTO Don Rippert which probably is the most rewarding thing an architect wants in his career.
This post is about some basic SOA Design Patterns that you should be familiar with. You can evaluate your existing application to see if they implement these patterns and if not then analyze the benefits of implementing the SOA Design patterns to make the applications SOA complaint. I assure you the benefits are immense in terms of maintainability, simplicity, loose coupling, reuse and atomic code. If you require any guidance feel free to write to me. I usually respond to queries on weekend.
1. Agnostic Services
Service capabilities derived from specific concerns may not be useful to multiple service consumers, thereby reducing the re-usability potential of the agnostic services. Agnostic services implement logic that is common to multiple business problems. Separating agnostic logic into discrete services facilitates service reuse and composability.
2. Service Declaration
Agnostic services should explicitly declare that they are agnostic. This makes it clear to future designers and builders which services are designed to be reused.
3. Atomic Service Transaction
Services can be wrapped in atomic transactions with a rollback feature that reverses all actions and changes. Transaction management services can be implemented in the component layer and reused by multiple services.
4. Enterprise Service Bus (ESB)
An ESB acts as a message broker between consumers and services. The ESB can perform message transformations, routing and connect to applications via a variety of communication protocols. YOu can use open source ESB products.
5. Service Façade
The service façade sits between a service and a contract. It eliminates the tight coupling between the service and its contract. This is intended to minimize changes to the service if the contract changes. A service can have multiple service façades to support multiple contracts.
6. Long Running Services & Service Callback
A service requires its consumers to call it asynchronously. If the consumer needs a response it provides a callback address. When the service reaches some milestone in processing it messages the consumer with a response. This approach frees resources and is useful when services are expected to be long running.
7. Backward Compatibility & Multiple Service Contracts
A service may support multiple contracts concurrently. This can be done to support backward compatibility (so that when a service changes all the consumers do not have to be updated). It is also done to provide different views to the service for different purposes (thus facilitating reuse).
8. Authentication Broker
In an enterprise scenario an authentication broker assumes responsibility for authenticating consumers. Consumers are issued a token they can use to access services.
9. Message Origin Authentication
Digital certificates are used to authenticate enterprise clients.
10. Message Filtering
Messages are filtered for harmful data before processing.

16) What implementation should an enterprise prioritize - Mobile Applications,SaaS or Big Data?
Mobile Revolution, SaaS & Big Data followed in succession. Each of these technologies changed the playing field and churned the markets. Yet their are over 70% enterprises that have not implemented mobile platforms, over 90% enterprises that have not leveraged SaaS and over 99% enterprises that have not taken any Big Data initiative as yet. Don't worry about the accuracy of numbers because this is my conservative estimate and real numbers could vary by a huge 20% but the proportion of implementation should be very close.
And for the enterprises that have yet to implement any of these 3 technologies it is quite a clallenge, There are enterprises that were on the verge of building their mobile platforms and suddenly got hit by the SaaS wave and then the Big Data wave.
Mobile Platform roll out is a challenge by itself and I have worked on projects that have gone back and forth on mobility platform at times because of lack of understanding of the mobility architecture and at other times due to their rigid service layer which would have to be rebuilt to cater to the mobile platform because of the 'Different Nature & Requirements of Mobile User Interface'. The challenge is around using your existing architecture ad capabilities to support the Mobile Application instead of replicating and rebuilding applications for mobile & we can say the challenge is to implement a classic Service Oriented Architecture to reuse the existing services of the enterprise applications.
SaaS or Software as a Service is value proposition and the need of the hour but it will take some time for enterprises to move to SaaS. To implement SaaS in true sense, apart from the challenges faced by Mobile implementation there are additional challenges across architecture layers. The good part is that three are multiple 'Multi-Tenancy Models' and an enterprise can implement SaaS incrementally and still derive the benefits of the shared model. My opinion is enterprise should start Mobile & SaaS implementation in parallel. Of course the need an experienced architect to guide them and the 1st step of each implementation would be to build a working prototype.It is also very important to educate the employee of the structural and cultural changes that come along adapting these 2 technologies but that is something we will not discuss here.
Finally Big Data, the Big Daddy everybody wants to tell the world that they have Got It Tamed but nobody knows whats will be the end result. No kidding! Ask Apple, Amazon, Bestbusy, IBM, Telstra, AT&T and many other who got started with a humble goal. This is because unless you have a clear understanding of the varacity of Bog Data for your enterprise and its applicability to various areas of business it does not make sense to invest in Big Data. So first things first is to study the changing industry landscape, revisit the enterprise vision and update it and then define the Big Data Vision. I think it is clear that Big Data implementation can follow as you start implementing Mobility and SaaS or even better have all three programs run in parallel if you can. I will be happy to exchange learning's with these technologies if you drop me a mail. Cheers!

15) Tribute to my Idol Scientist & Ex President APJ Abdul Kalam (aka. Father of Indian Nuclear Program & Missile Man)
Most hard working people retire at age of 75 and enjoy a relaxed lifestyle. Those who are fit like to travel across the globe visiting countries & enjoying life and there are few 84 years old people like Indian Ex-President APJ Abdul Kalam who continue to work 24/7, sharing their vision & experience with the youth and guiding them. It is interesting that at the age of 84 Mr Kalam would share his personal email-id at a press conferences & invites people to write to him and guarantees a reply with 24 hours. I have been proud of the fact that I always reply to my business emails, the same day I receive them but I cannot imagine myself sharing my email-id with entire India and replying to any question on any subject 24/7 like Kalam did, it takes Mr.Kalam to Just Do It.
I become Mr.Kalam's fan when I heard his interview after 'Pokhran' nuclear test which made India became a nuclear power under his leadership. Most people don't realize the impact of becoming a Nuclear power and if you read last few years of history you will realize the change in world's outlook towards India pre/post becoming a Nuclear power. Interestingly it took two most honest and non-violent people Atal Bihari Vajpaye & Dr Kalam to finally make it happen. When a reporter asked him 'Why does India need a nuclear bomb?' Dr.Kalam's reply was ' Today the world's top 4 nations are nuclear power and if India wants to be 'Heard as a leader' we cannot sit and do Tapas ( Tapas or Tapsya meaning Doing Penance)'. To be heard as a leader India needs to be one of the top 5 powerful nations and that is why India had to develop its nuclear program.' If you have heard his lectures would know that Dr. Kalam approach was always Practical, Precise and to the Point and he conveyed his ideas in a very polite way. I like his examples of what a good leader should be like. He said a good leader should face the world and own teams failures & when the team succeeds the leader should let the team take the center stage and he himself should take a back seat - I wish we had more and more leaders following his example. There are far too many leaders who are too eager to own the credit that at times rightfully belongs to someone else or the entire team. He said leaders are watched by people and followed so their integrity should be beyond question and at 84th year of his life he enjoys the popularity because of his honesty, integrity & character. Kalam said a leader should be courageous and should be able to take difficult decisions. I have seen leaders who have been scared of taking tough decisions even when the risk was minimal and the leader fails to understand that a wrong decision put his team back by ages. I wish Indian political leaders would start following Kalam's principles if only to become popular and succeed like Dr.Kalam because no Indian has tasted success like Dr.Kalam in recent years.
I can think of few leadership principles that may not be part of Dr Kalam's speeches but I have observed these qualities in Mr.Kalam and many other good leaders.
1) A leader should be friendly and approachable to everybody in his team - remember Mr.Kalam himself used to read emails sent by anybody & ever body even after he retired.
2) A leader should regularly communicate with his team. Leader's communication should be crisp and to the point and he should listen to the spoken and unspoken.
3) Leader should seek opportunity to appreciate his team rather than finding faults in his team and the team will work hard to seek his appreciation
I did not have the fortune to meet the great APJ but I always felt I had a connect with the man. I guess each patriotic Indian today feels that he has a connect with APJ Abdul Kalam and that is what makes him People's President - a loving title that no other president in the world has been bestowed with by the people. I am happy my son has a modern Indian Idol to follow and I can tell him stories of the great Dr APJ Abdul Kalam.
Rest in peace Sir, Dr Avul Pakir Jainulabdeen Abdul Kalam. You will always be loved and remembered by India
I become Mr.Kalam's fan when I heard his interview after 'Pokhran' nuclear test which made India became a nuclear power under his leadership. Most people don't realize the impact of becoming a Nuclear power and if you read last few years of history you will realize the change in world's outlook towards India pre/post becoming a Nuclear power. Interestingly it took two most honest and non-violent people Atal Bihari Vajpaye & Dr Kalam to finally make it happen. When a reporter asked him 'Why does India need a nuclear bomb?' Dr.Kalam's reply was ' Today the world's top 4 nations are nuclear power and if India wants to be 'Heard as a leader' we cannot sit and do Tapas ( Tapas or Tapsya meaning Doing Penance)'. To be heard as a leader India needs to be one of the top 5 powerful nations and that is why India had to develop its nuclear program.' If you have heard his lectures would know that Dr. Kalam approach was always Practical, Precise and to the Point and he conveyed his ideas in a very polite way. I like his examples of what a good leader should be like. He said a good leader should face the world and own teams failures & when the team succeeds the leader should let the team take the center stage and he himself should take a back seat - I wish we had more and more leaders following his example. There are far too many leaders who are too eager to own the credit that at times rightfully belongs to someone else or the entire team. He said leaders are watched by people and followed so their integrity should be beyond question and at 84th year of his life he enjoys the popularity because of his honesty, integrity & character. Kalam said a leader should be courageous and should be able to take difficult decisions. I have seen leaders who have been scared of taking tough decisions even when the risk was minimal and the leader fails to understand that a wrong decision put his team back by ages. I wish Indian political leaders would start following Kalam's principles if only to become popular and succeed like Dr.Kalam because no Indian has tasted success like Dr.Kalam in recent years.

Session Token In URL Vulnerability
The HTTP protocol and web servers are stateless by nature. This means that there is no way for them to track user activity. The web server treats every request as a new one. For this reason, browsers and web servers need to use session tokens. Session tokens are unique pieces of information shared between the browser and the server. They make it possible to track user activity and differentiate between users. For example, an e-commerce application may use a session token to identify the shopping cart that belongs to a particular user.
There are different ways to share session tokens. They are most commonly included in cookies but alternative methods are quite widespread as well. Such methods include sending the session tokens directly in URLs, in dynamically rewritten URLs, or hidden in the HTML source of the web page. These methods are also often combined and on the rise because users often disable cookies in web browsers due to privacy concerns.
Why Is Using Session Tokens in URLs a Bad Idea?
The easiest method of sharing session tokens is placing one directly in the URL, for example, http://www.example.com/account.php?token=12345. Using such an URL, a user who was authenticated earlier can access their account. This method is not inherently insecure but if the session token is not validated by the server, it could lead to potentially high-risk vulnerabilities.
If you place a session token directly in the URL, it increases the risk of an attacker capturing and exploiting it. Anyone who follows that URL inherits the session. When you connect to the web server using HTTPS the risk is less than if you use HTTP but it is still a threat.
HTTPS URLs are encrypted during transmission but they are often stored in server logs. Anyone who gains access to the logs can exploit these tokens. In the worst case, this can lead to session fixation or session hijacking. Therefore, even though we classify the Session Token in URL vulnerability as low severity, you should not take it lightly.
What Are the Alternatives?
Applications should use alternative methods of sharing session tokens, for example, HTTP cookies. You should also encrypt such applications because it is possible to retrieve session tokens from unencrypted applications.If you cannot use cookies, you can send session tokens using hidden input fields. Unfortunately, this is also not foolproof. Attackers may explore the HTML source code to identify and hack hidden fields used to send these tokens. For more on Session hacking read my post about

13) How Big Data Can Fuel Bigger Growth for Your Company
Why should you care about Big Data?
In today’s challenging environment, how will companies grow? The answer is the most valuable yet untapped asset - Customer Information. Consider how companies are using 'sensors & telematics systems' in cars to offers lower insurance premiums to its car customers, How online retailers are integrating social media to understand the customer sentiments, how credit card companies are Customer Behavior data to target direct marketers. It is clear that companies are opening new organic revenue streams by tapping their data & building an information services growth engine.What can companies do about it?
Before launching a new information business, companies should assess whether they have enough information to differentiate themselves in the marketplace, have data elements that are difficult to replicate in the marketplace, and can combine their data with information from others sources & use sophisticated analysis to create differentiated products. If the assessment reveals there is sufficient revenue potential from an information services business, companies should consider :- Consider the best applications of your data (Ex- Marketing, Risk Management, R&D, Operational effectiveness)
- Compare the attractiveness of the information service to the service offered by existing players (also validate the information services strategy with potential strategic customers)
- Understand which important capabilities or assets they will need to win business in the information services
- Assess the legal, privacy and policy implications of monetizing information assets
- Design the most appropriate go-to market approach
- Use an accelerated prototyping approach to get the new offers into the market quickly
How do you get the started on the journey?
Focus on following 7 step could help companies get started on using Big Data to build a information service business
- To what extent does your organization use customer data to drive growth?
- Have you launched new products, services, or businesses focused on the value of your customer information? If so, how successful have those offers been in the marketplace?
- Do you feel your customer information-based offers are sufficiently differentiated?
- Do you have a detailed information management strategy tailored to your organization’s unique requirements?
- How does your organization prioritize information sources as they relate to corporate strategy?
- With the proper analysis of data from multiple sources, could you develop more innovative and competitive offerings?
- How much potential insight do you think is locked up in inaccessible data sources?
