Transcript

  • 1.  Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. NIST Shared Infrastructure Dynamic Provisioning Managed Metering Network Access
  • 2. Cloud computing is an evolving paradigm. It is a potential technology to change IT Services. The elasticity of resources plays an important part in cloud computing. Cloud computing provides, OnDemand Services Broad Network Access Measured Services Resource Rapid Pooling Elasticity

  • 5. Easy Connectivity Inexpensive Efficient Storage and Computing Widespread Availability Reliable and Redundant
  • 6.  Cloud computing makes eminent sense for small scale enterprises. With no upfront investment; it allows SMEs a cost effective solution with their capital.  It just a flat monthly rate and you’re sorted; no need to worry about buying those expensive hardware solutions or to take care of scalability issues.  As per your business demands; you can scale up and down. Cloud computing provides better functionality then a conventional solutions which are so expensive.
  • 7.  Cloud computing provides mobility; be it your office or a comfort of your own home, you can access your business software and all you need to do is ‘Login’.  Cloud computing makes sharing a cake walk. It expands your business boundaries.  Better resilience and security is a key feature of cloud computing which SMEs couldn’t afford otherwise.  Cloud computing effectively cuts down the labor cost up to 15-20%.
  • 8.  When it comes to implying mission-critical application; large scale enterprise gives cloud system a second thought.  As the mission-critical application has sensitive information, vulnerability issues are higher; that’s the main reason for large scale enterprise to not adapt cloud computing as it still contains some deficiencies.  Though the scenario is changing these days, especially after Microsoft office 365 adopted cloud computing.
  • 9.  Hybrid cloud is a solution for large scale enterprises when affordability of public cloud and security of private cloud is needed.  Cloud computing provides best breed of services if it is managed well by the large scale enterprises.  Cloud computing implies “Green approach”, we are not just talking about environment; cloud computing also cuts down the expenditures of large scale enterprise by 30%. Energy cost goes tremendously down by adapting cloud computing.
  • 10.  Cloud computing has several security loopholes which makes it vulnerable.  Cloud computing is yet to adhere several regulatory requirements and security laws.  As cyber policy differs from country to country, there are some legal issues in cloud computing.  Confidentiality is the major issue in cloud system, as all the information is stored at remote location.  Another big issue with cloud system is encryption; it is very essential for ensuring the security of data which is yet to be implemented.
  • 11.  Denial of Service attack: Denial of service attacks are the most common hacking attacks. Hackers flood network host by invalid requests that occupies all the resources. This ultimately affects in responding the legitimate requests.  Authentication attack: In hosted and virtual services, authentication is a weak point. The methods and mechanism used to secure the authentication process are frequently targeted.  Side channel attack: Malicious virtual machine in close proximity to host system is placed in host system. Side channel attack has emerged as effective security threat targeting systems. Hence resilience to side channel attack is important.  Man in middle attack: In man in middle attack, attacker gets in the middle of our interactions with others and eavesdrops on data coming back and forth.
  • 12. Research is being done on security issues in cloud computing system. Researchers are still discovering the security issues that are needed to be resolved in order to provide reliable and robust solutions.
