  • IBM India Private Limited: Update on Material Event
    October 20, 2020 IBM India Private Limited: Update on Material Event Summary of rating action Instrument* Rated Amount (Rs. crore) Rating outstanding [ICRA]AAA (Stable) / [ICRA]A1+; Long-term/Short-term – Proposed facilities 150.00 outstanding Short-term - Non-fund Based 20.00 [ICRA]A1+; outstanding Long-term (Interchangeable) (20.00) [ICRA]AAA (Stable); outstanding Total 170.00 Material Event On October 8, 2020, International Business Machines Corporation, USA (IBM Corporation; rated A2/stable/P1 by Moody’s) has announced its decision to spin off its managed infrastructure services unit of global technology services (GTS) division into a separate public company by the end of 2021, subject to regulatory approvals. The spin-off is to sharpen its focus on high-margin open hybrid cloud platform and artificial intelligence (AI) capabilities. Subsequently, on October 10, 2020, based on media articles, it is noted that the Indian operations, which are currently carried on under IBM India Private Limited (IBM India), would be restructured as well and around one-fourth of its employees will be part of the new entity catering to the needs of managed IT infrastructure services. Impact of the Material Event IBM India is one of the key global delivery centres for IBM Corporation with over 70% of its revenues being derived from export of services to the parent entity and its fellow subsidiaries, as part of the outsourcing business model. The company derives over 20% of its revenues from technology services, cloud platform and global business services division, wherein IBM India provides infrastructure services and technology support services to its clients.

  • IBM India Private Limited: Ratings of [ICRA]AAA (Stable)/ [ICRA]A1+ Assigned
    September 23, 2020 IBM India Private Limited: Ratings of [ICRA]AAA (Stable)/ [ICRA]A1+ assigned Summary of rating action Current Rated Amount Instrument* Rating Action (Rs. crore) Long-term/Short-term – Proposed facilities 150.00 [ICRA]AAA (Stable) / [ICRA]A1+; assigned Short-term - Non-Fund based 20.00 [ICRA]A1+; assigned Long-term (Interchangeable) (20.00) [ICRA]AAA (Stable); assigned Total 170.00 Rationale The assigned ratings favourably factor in the strong parentage of IBM India Private Limited (IBM India), being a step- down subsidiary of International Business Machines Corporation, USA (IBM Corporation; rated A2/stable/P1 by Moody’s), experienced management team, strong operational and strategic linkages with IBM Corporation, and its healthy financial and operational profile with presence across various end-user industries. Being part of IBM Corporation, a global leader in providing information technology (IT)-related services and products, IBM India has access to the strong expertise and capabilities in the business of the latter. India is a key market for IBM Corporation, although its share in the overall revenues is less (<5%) because of the demographic advantage of availability of low-cost labour and large, skilled talent pool. The company is one of the key global delivery centres at the Group level and derived over 70% of its revenues in FY2020 from export of services to its parent and fellow subsidiaries on a cost- plus model. IBM India’s credit profile is characterised by its large scale of operations, stable earnings and cashflows, net debt-free status and strong liquidity profile. The Covid-19 pandemic has adversely impacted the Indian and global IT services industry, causing disruption to both supply (restriction of movement of employees) and demand (like delayed offtake of new projects, reduced discretionary spend and IT budget cuts).

  • A Complete Survey on Software Architectural Styles and Patterns
    Available online at www.sciencedirect.com ScienceDirect Procedia Computer Science 70 ( 2015 ) 16 – 28 4th International Conference on Eco-friendly Computing and Communication Systems, ICECCS 2015 A Complete Survey on Software Architectural Styles and Patterns Anubha Sharmaa*,Manoj Kumarb, Sonali Agarwalc a,b,cIndian Institute of Information Technology,Allahabad 211012,India Abstract Software bought revolutionary change making entrepreneurs fortunate enough to make money in less time with least effort and correct output. SDLC (Software development life cycle) is responsible for software’s reliability, performance, scalability, functionality and maintainability. Although all phases of SDLC have their own importance but Software architecture serves as the foundation for other phases of SDLC. Just like sketch of a building helps constructor to correctly construct the building, software architecture helps software developer to develop the software properly. There are various styles available for software architecture. In this paper, clear picture of all important software architecture styles are presented along with recent advancement in software architecture and design phases. It could be helpful for a software developer to select an appropriate style according to his/her project’s requirement. An architectural style must be chosen correctly to get its all benefits in the system. All the architectural styles are compared on the basis of various quality attributes. This paper also specifies the application area, advantages and disadvantages of each architectural style. © 20152015 The The Authors. Authors. Published Published by byElsevier Elsevier B.V. B.V.

  • Innovative Feedback System Based on Ibm Bluemix Cloud Service
    INNOVATIVE FEEDBACK SYSTEM BASED ON IBM BLUEMIX CLOUD SERVICE P.P.N.G. Phani Kumar1, N. Anil Chakravarthy2, D.V.S.Ravi Varma3, M.Y.V.Nagesh4 1,2,3,4 Assistant Professor, Department of CSE, Raghu Engineering College, Visakhapatnam, (India). ABSTRACT Getting the right feedback at right time is most important for any organization or an institution. Getting the feedback from the users will help an organization or institution to provide better services to the users or students. Ongoing interaction with users can improve the efficiency of an organization and enable them to provide better service to the users. Until now, several feedback systems are in use which are mostly manual. We propose an efficient feedback system using cloud based computing to generate the report of the faculty performance. In the proposed system all the activities will be done by the use of cloud application Platform as a Service, through the use of IBM Bluemix. Keywords: Android, Bluemix, Cloud Computing, Paas (Platform As A Services) I INTRODUCTION Cloud Computing[1] is a popular technology in which internet and central remote servers are used to store and maintain the data, applications. Cloud computing allows people to use applications without installation of any specialized software and access the required computing facilities from anywhere via internet. By using Cloud computing we can achieve much more efficient computing power by centralizing data storage, processing and bandwidth. Cloud can be available as various services Software as a service (SaaS), Platform as a service (PaaS), Infrastructure as a service (IaaS) 1.1 Services Fig.1: Cloud Computing Services 260 | P a g e Software as a service (SaaS): Software as a service is one type of cloud service in which an application software is installed and manage in the cloud.
