Cloud Computing

Hi Manisha,
Cloud computing is the delivery of computing and storage capacity as a service to a community of end-recipients. The name comes from the use of a cloud-shaped symbol as an abstraction for the complex infrastructure it contains in system diagrams. Cloud computing entrusts services with a user's data, software and computation over a network.There are three types of cloud computing:
1.Infrastructure as a Service (IaaS),
2.Platform as a Service (PaaS), and
3.Software as a Service (SaaS).
Employers will want you to have exposure to or experience working with the technologies of one of the four big cloud computing companies: Amazon, Google, Microsoft or Salesforce.com, and/or experience working with virtualization technologies such as that of VMWare.
Other requirements may include:
BA/BS degree in engineering, computer science or related field;
Network and security architecture experience;
Experience with a cloud migration, data center migration, or server consolidation project;
Knowledge of and experience with technologies such as Java, Web services, SOAP and Ajax;
communication, teamwork and problem-solving skills.

The Training and Placement Unit of the Institute is responsible for providing world class job opportunities to the undergraduate and postgraduate students after graduation for suitable jobs in the industry and various private and public sector organizations. No institute can guarantee you placements. It's just purely based on how you utilize your abilities and skills at the right time.
Salary is a function of various factors - i.e. (i) the institute where you have completed your B.Tech + M.Tech. e.g. a graduate from a top institute will command a higher salary. (ii) Your work experience - organization and type of work profile (iii) city - a metropolitan city will have higher salaries as compared to smaller cities and towns. (iv) Your current organization - i.e. where you will be joining - an MNC usually has higher salaries as compared to other organization.
Hope this information helps.
Wish You Luck!

Hi Gunjan,
There are various challenges related to cloud computing data security, listed below are some of them :
1. Multi-tenancy - makes it easier for a hacker to steal the data of all business customers who share the same cloud database.
2. Threats of data loss and data leakage -the threat of data leakage increases when employees use their mobile devices to access and share corporate documents via cloud storage services such as DropBox, Box etc.,
3. Insecure APIs - Most Cloud service providers do not pay attention to the security of their APIs which can pose risks to an enterprise data with regards to privacy and data integrity.
4. Encryption - Most government regulations (HIPAA, PCI) require that data encryption. Although encryption is widely used, it is often implemented poorly. Many companies depend on the cloud provider for encrypting data which means that have control of the key & can access the data anytime.
All the Best
