Role of SMAC in evolution of Digital India

Introduction:

Digital technologies which include Social, Mobility, Analytics and Cloud applications have emerged as a catalyst for rapid economic growth and citizen empowerment across the globe. This vision is to empower every citizen of the country of Bharat (India) with access to digital services, knowledge and information. Department of Electronics and Information Technology (DeitY) has taken the collaborative approach towards achieving the three visions and 9 pillars of Digital India. DeitY has launched a digitally enabled platform called “MyGov” (mygov.in) to provide collaborative and participating governance.

 

The three visions digital India programs are

· Digital infrastructure as a utility to every citizen (Vision-1)

· Governance and services on demand (Vision-2)

· Digital empowerment of citizen (Vision-3)

 

There are Nine pillars of digital India program. They are as follows.

· Broadband highways

· Universal access to mobile connectivity

· Public internet access program

· e-Governance- Reforming government through technology

· eKranti- Electronic delivery of services

· Information for all

· Electronic manufacturing

· IT for jobs

· Early harvest programs

 

The Role of Social:

Social media like Facebook, Twitter, LinkedIn allows people to connect to share views, likeness, opinions anywhere and anytime without any delay. These interaction benefits corporate and the government analyze the data and make decisions regarding products and services. For this we require high speed internet so that as many as people from rural and urban areas can connect with each other and access various services online. While accessing any service their digital identity will be identify through Aadhar card. Since English is the official language of India accessing any service people from rural and urban areas will face problems. Therefore digital resources/services will be available in Indian languages so that human-machine interaction takes place without language barriers. This will create multilingual knowledge resources. Therefore social media will be basically used for marketing, internal collaboration and data analysis.

 

The Role of Mobility:

Mobility is the critical part of national e-Governance (NeGP) projects in India currently being implemented under Central and State levels. NeGP has performed various works such as stack holder needs analysis, project planning and measurement, process reforms etc. Perform survey and stockholder need analysis involve need of citizens at rural and urban areas, need of business, need of government employees at state and central level.

Based on the above survey and analysis central and state government perform large scale e-Governance project planning of service delivery through mobile phones, making the mobile phone the central of service delivery. This results participation of people from urban and rural areas in digital and financial space through mobile and banking, seamlessly integrated services, single window access to services, services in real time online and mobile platforms, digital transformed services for improving ease of doing business, making financial transactions online through internet banking, Rupay debit card etc. no cash transaction, leveraging GIS for decision support system, universal digital literacy at individual level etc.

Apart from this different services provided in rural and urban areas as mobile as the central point of delivery of all services given as follows-

· m-health (mobile based health and medicine consultancy)

· m-education (mobile based virtual education classrooms in local languages at all levels)

· m-biometric identity authentication (mobile based identity through Aadhar)

· m-agriculture (mobile based monitoring management, agri-extension advice and sale)

· m-elections (mobile based online voting based authentication)

· m-rural development (mobile based various rural development projects based on mobile)

· m-panchayat (mobile based panchayat services delivered on mobile)

 

The Role of Analytics:

Analytics refers to Big data. Big data means data available in both structured and unstructured form integrated with multiple, diverse, dynamic sources of information. In fact big data is defined as data that exhibit the 4V properties- value, volume, velocity and veracity. Analyzing this huge amount of data to get the pattern and relevant useful information is called analytics. Big data based analytics can be used in many of the campaigns and election results.

Availability of digital information in India is growing very fast. Data available in enterprise, the volume of data available by the government is also increasing. There are government funded initiatives such as data portal India or Aadhar which are promising directions to enable big data applications relevant to India.

 

There are many challenges to handle large set of data such as

· Efficient architecture and infrastructure of data capturing, data analytics, data delivery, data visualization and data management

· Making data driven decisions

· Data analytics from specification of e-Health, e-Education, e-Governance etc. are yet to be identified

· Integrating big data platform (such as Hadoop) into existing data warehouses

· Security and privacy issues of data being shared for analysis or public consumption are also important to address

· Discovering patterns, predictive analytics and other insights from big data is a non-trivial problem and provides lots of opportunities to innovate in the algorithm innovation

 

The Role of Cloud:

According to NIST definition Cloud Computing is a model for enabling, convenient, ubiquitous on-demand network access to a shared resources (e.g., networks, servers, storage, applications, and services) that can be gradually provisioned and launched with minimal management and service provider interaction. Cloud has five essential properties like on demand self-service, broad network access, resource pooling, rapid elasticity and measured service.Apart from this Cloud Computing has three cloud service models (IaaS, PaaS, and SaaS), and four cloud deployment models (private, public, hybrid, and community).

Through digital India initiatives sharable public Cloud will be available through digital lockers or Digilocker. It enables the people to digitally keep their important documents like PAN card, passport, mark sheets and degree certificates. Digital locker also provide secure accessibility to Government issued documents. It uses authentication services provided by Aadhaar.

 

Cloud Computing has several challenges in India. They are outlined as follows:

· Achieve global leadership in India in Cloud Computing uses, services, offerings and innovation.

· Accelerate national adoption in Cloud Computing technologies, driven by local expertise.

· Develop an innovative framework for Cloud Computing initiatives in India.

· Different other aspects like interoperability, privacy and security.

· Create an environment for multi-stack holder partnership and joint progress.

 

There are also six trends of Cloud Computing.

1. Multinational companies are looking for new business growth opportunities using modern information technology solution. The SMAC has created interesting use cases for businesses. Therefore business growth and IT cost reduction is the ultimate goal.

2. Many leading IT industries in different fields are taking the entire business like Amazon- the World’s largest book store, iTune- the World’s largest music company, Facebook- the World’s largest social site etc.

3. Cloud is becoming a major evolution step in IT market. Its adoption basically depends upon client cost, service, multi-tenant technology and multi-shared delivery model.

4. Enterprise boundaries are getting redefined. Cloud based IT solutions integrated with social media and analytics bring higher value. Therefore IT companies need to integrate with their partners, suppliers and other areas of ecosystem.

5. Make in India initiatives will drive innovation relevant to India Cloud market. Since 2010 70% of India software is developed based on Cloud platform. These products can provide globalize solutions.

6. The combined Cloud service market (public and private) was $0.9 billion in 2011 while in 2015 it has increased up-to U.S $4.5 billion accounting to more than 3% of the global market.

 

Conclusion:

SMAC based IT solutions are identified as a multi-billion dollar prospect for the IT sectors in the world. The corporate and governments are increasingly adopting these technologies, as they become more agile with resource sharing within organization and seek more awareness about their customers to serve them better. Global IT market is being flourishing hugely with SMAC strategies fulfilling the needs in a well-organized manner and promising the prospects of the future of Digital India program. Last but not the list it is just the beginning of a digital revolution, and it will create more job opportunities in IT sector in next 5 years in India.
